From: Arnd Bergmann <arnd@arndb.de>
The virt_to_bus/bus_to_virt interface has been deprecated for
decades. After Jakub Kicinski put a lot of work into cleaning out the
network drivers using them, there are only a couple of other drivers
left, which can all be removed or otherwise cleaned up, to remove the
old interface for good.
Any out of tree drivers using virt_to_bus() should be converted to
using the dma-mapping interfaces, typically dma_alloc_coherent()
or dma_map_single()).
There are a few m68k and ppc32 specific drivers that keep using the
interfaces, but these are all guarded with architecture-specific
Kconfig dependencies, and are not actually broken.
There are still a number of drivers that are using virt_to_phys()
and phys_to_virt() in place of dma-mapping operations, and these
are often broken, but they are out of scope for this series.

From: Arnd Bergmann <arnd@arndb.de>
This is one of four remaining drivers using the ancient
virt_to_bus() interface instead of the dma-mapping interface,
making it incompatible with most modern machines.
As nobody has cleaned this up, there is a high chance that this
driver has no actual users. The chip was introduced in 1997 and
only supports 32-bit legacy PCI. It was replaced by TSI148 in
2004, but that chip has since been discontinued, while a version
of the older Universe II remains in production after 25 years.
The vme_vmivme7805 board uses Universe-II, so this also gets
removed in the process, but PCI add-on cards based on TSI148
can still work in theory.
If there are users of the Universe-II driver after all, it is
of course possible to revert this patch and fix it to use the
dma-mapping interface like the tsi148 driver does.

* [PATCH 1/6] vme: remove ca91cx42 Universe-II support
@ 2022-06-06 8:41 ` Arnd Bergmann

From: Arnd Bergmann <arnd@arndb.de>
This is one of four remaining drivers using the ancient
virt_to_bus() interface instead of the dma-mapping interface,
making it incompatible with most modern machines.
As nobody has cleaned this up, there is a high chance that this
driver has no actual users. The chip was introduced in 1997 and
only supports 32-bit legacy PCI. It was replaced by TSI148 in
2004, but that chip has since been discontinued, while a version
of the older Universe II remains in production after 25 years.
The vme_vmivme7805 board uses Universe-II, so this also gets
removed in the process, but PCI add-on cards based on TSI148
can still work in theory.
If there are users of the Universe-II driver after all, it is
of course possible to revert this patch and fix it to use the
dma-mapping interface like the tsi148 driver does.

* [PATCH 1/6] vme: remove ca91cx42 Universe-II support

From: Arnd Bergmann <arnd@arndb.de>
This is one of four remaining drivers using the ancient
virt_to_bus() interface instead of the dma-mapping interface,
making it incompatible with most modern machines.
As nobody has cleaned this up, there is a high chance that this
driver has no actual users. The chip was introduced in 1997 and
only supports 32-bit legacy PCI. It was replaced by TSI148 in
2004, but that chip has since been discontinued, while a version
of the older Universe II remains in production after 25 years.
The vme_vmivme7805 board uses Universe-II, so this also gets
removed in the process, but PCI add-on cards based on TSI148
can still work in theory.
If there are users of the Universe-II driver after all, it is
of course possible to revert this patch and fix it to use the
dma-mapping interface like the tsi148 driver does.

From: Arnd Bergmann <arnd-r2nGTMty4D4@public.gmane.org>
This is one of four remaining drivers using the ancient
virt_to_bus() interface instead of the dma-mapping interface,
making it incompatible with most modern machines.
As nobody has cleaned this up, there is a high chance that this
driver has no actual users. The chip was introduced in 1997 and
only supports 32-bit legacy PCI. It was replaced by TSI148 in
2004, but that chip has since been discontinued, while a version
of the older Universe II remains in production after 25 years.
The vme_vmivme7805 board uses Universe-II, so this also gets
removed in the process, but PCI add-on cards based on TSI148
can still work in theory.
If there are users of the Universe-II driver after all, it is
of course possible to revert this patch and fix it to use the
dma-mapping interface like the tsi148 driver does.

From: Arnd Bergmann <arnd@arndb.de>
The VME subsystem graduated from staging into a top-level subsystem in
2012, with commit db3b9e990e75 ("Staging: VME: move VME drivers out of
staging") stating:
The VME device drivers have not moved out yet due to some API
questions they are still working through, that should happen soon,
hopefully.
However, this never happened: maintenance of drivers/vme effectively
stopped in 2017, with all subsequent changes being treewide cleanups.
No hardware driver remains in staging, only the limited user-level
access, and I just removed one of the two bridge drivers and the only
remaining board.
drivers/staging/vme/devices/ was recently moved to
drivers/staging/vme_user/, but as the vme_user driver is the only one
remaining for this subsystem, it is easier to just move the remaining
three source files into this directory rather than keeping the original
hierarchy.

* [PATCH 2/6] vme: move back to staging
@ 2022-06-06 8:41 ` Arnd Bergmann

From: Arnd Bergmann <arnd@arndb.de>
The VME subsystem graduated from staging into a top-level subsystem in
2012, with commit db3b9e990e75 ("Staging: VME: move VME drivers out of
staging") stating:
The VME device drivers have not moved out yet due to some API
questions they are still working through, that should happen soon,
hopefully.
However, this never happened: maintenance of drivers/vme effectively
stopped in 2017, with all subsequent changes being treewide cleanups.
No hardware driver remains in staging, only the limited user-level
access, and I just removed one of the two bridge drivers and the only
remaining board.
drivers/staging/vme/devices/ was recently moved to
drivers/staging/vme_user/, but as the vme_user driver is the only one
remaining for this subsystem, it is easier to just move the remaining
three source files into this directory rather than keeping the original
hierarchy.

From: Arnd Bergmann <arnd-r2nGTMty4D4@public.gmane.org>
The VME subsystem graduated from staging into a top-level subsystem in
2012, with commit db3b9e990e75 ("Staging: VME: move VME drivers out of
staging") stating:
The VME device drivers have not moved out yet due to some API
questions they are still working through, that should happen soon,
hopefully.
However, this never happened: maintenance of drivers/vme effectively
stopped in 2017, with all subsequent changes being treewide cleanups.
No hardware driver remains in staging, only the limited user-level
access, and I just removed one of the two bridge drivers and the only
remaining board.
drivers/staging/vme/devices/ was recently moved to
drivers/staging/vme_user/, but as the vme_user driver is the only one
remaining for this subsystem, it is easier to just move the remaining
three source files into this directory rather than keeping the original
hierarchy.

From: Arnd Bergmann <arnd@arndb.de>
This driver does not use the virt_to_bus() function, though it
depends on x86 specific fixups in the swiotlb code, which was
last rewritten in commit e380a0394c36 ("x86/PCI: sta2x11: use
default DMA address translation").
It is possible that the driver still fails to build on some
architectures that are missing CONFIG_VIRT_TO_BUS, but it is
always set on x86 machines with the STA2X11 platform enabled.
More likely though is that it was never meant to depend on
CONFIG_VIRT_TO_BUS, and the Kconfig dependency was kept from
an out-of-tree version when the driver was originally merged.
Fixes: efeb98b4e2b2 ("[media] STA2X11 VIP: new V4L2 driver")

From: Arnd Bergmann <arnd@arndb.de>
The dpt_i2o driver was fixed to stop using virt_to_bus() in 2008 but
it a stale reference in a broken error handling code path that could
never work.
Fix it up to build without VIRT_TO_BUS and remove the Kconfig dependency.
The alternative to this would be to just remove the driver, as it is
clearly obsolete. The i2o driver layer was removed in 2015 with commit
4a72a7af462d ("staging: remove i2o subsystem"), but the even older
dpt_i2o scsi driver stayed around.
The last non-cleanup patches I could find were from Miquel van
Smoorenburg and Mark Salyzyn back in 2008, they might know if
there is any chance of the hardware still being used anywhere.

From: Arnd Bergmann <arnd@arndb.de>
The BusLogic driver is the last remaining driver that relies on the
deprecated bus_to_virt() function, which in turn only works on a few
architectures, and is incompatible with both swiotlb and iommu support.
Before commit 391e2f25601e ("[SCSI] BusLogic: Port driver to 64-bit."),
the driver had a dependency on x86-32, presumably because of this
problem. However, the change introduced another bug that made it still
impossible to use the driver on any 64-bit machine.
This was in turn fixed in commit 56f396146af2 ("scsi: BusLogic: Fix
64-bit system enumeration error for Buslogic"), 8 years later.
The fact that this was found at all is an indication that there are
users, and it seems that Maciej, Matt and Khalid all have access to
this hardware, but if it took eight years to find the problem,
it's likely that nobody actually relies on it.
Remove it as part of the global virt_to_bus()/bus_to_virt() removal.
If anyone is still interested in keeping this driver, the alternative
is to stop it from using bus_to_virt(), possibly along the lines of
how dpt_i2o gets around the same issue.

-Introduction
-============
-
-BusLogic, Inc. designed and manufactured a variety of high performance SCSI
-host adapters which share a common programming interface across a diverse
-collection of bus architectures by virtue of their MultiMaster ASIC technology.
-BusLogic was acquired by Mylex Corporation in February 1996, but the products
-supported by this driver originated under the BusLogic name and so that name is
-retained in the source code and documentation.
-
-This driver supports all present BusLogic MultiMaster Host Adapters, and should
-support any future MultiMaster designs with little or no modification. More
-recently, BusLogic introduced the FlashPoint Host Adapters, which are less
-costly and rely on the host CPU, rather than including an onboard processor.
-Despite not having an onboard CPU, the FlashPoint Host Adapters perform very
-well and have very low command latency. BusLogic has recently provided me with
-the FlashPoint Driver Developer's Kit, which comprises documentation and freely
-redistributable source code for the FlashPoint SCCB Manager. The SCCB Manager
-is the library of code that runs on the host CPU and performs functions
-analogous to the firmware on the MultiMaster Host Adapters. Thanks to their
-having provided the SCCB Manager, this driver now supports the FlashPoint Host
-Adapters as well.
-
-My primary goals in writing this completely new BusLogic driver for Linux are
-to achieve the full performance that BusLogic SCSI Host Adapters and modern
-SCSI peripherals are capable of, and to provide a highly robust driver that can
-be depended upon for high performance mission critical applications. All of
-the major performance features can be configured from the Linux kernel command
-line or at module initialization time, allowing individual installations to
-tune driver performance and error recovery to their particular needs.
-
-The latest information on Linux support for BusLogic SCSI Host Adapters, as
-well as the most recent release of this driver and the latest firmware for the
-BT-948/958/958D, will always be available from my Linux Home Page at URL
-"http://sourceforge.net/projects/dandelion/".
-
-Bug reports should be sent via electronic mail to "lnz@dandelion.com". Please
-include with the bug report the complete configuration messages reported by the
-driver and SCSI subsystem at startup, along with any subsequent system messages
-relevant to SCSI operations, and a detailed description of your system's
-hardware configuration.
-
-Mylex has been an excellent company to work with and I highly recommend their
-products to the Linux community. In November 1995, I was offered the
-opportunity to become a beta test site for their latest MultiMaster product,
-the BT-948 PCI Ultra SCSI Host Adapter, and then again for the BT-958 PCI Wide
-Ultra SCSI Host Adapter in January 1996. This was mutually beneficial since
-Mylex received a degree and kind of testing that their own testing group cannot
-readily achieve, and the Linux community has available high performance host
-adapters that have been well tested with Linux even before being brought to
-market. This relationship has also given me the opportunity to interact
-directly with their technical staff, to understand more about the internal
-workings of their products, and in turn to educate them about the needs and
-potential of the Linux community.
-
-More recently, Mylex has reaffirmed the company's interest in supporting the
-Linux community, and I am now working on a Linux driver for the DAC960 PCI RAID
-Controllers. Mylex's interest and support is greatly appreciated.
-
-Unlike some other vendors, if you contact Mylex Technical Support with a
-problem and are running Linux, they will not tell you that your use of their
-products is unsupported. Their latest product marketing literature even states
-"Mylex SCSI host adapters are compatible with all major operating systems
-including: ... Linux ...".

-94555, USA and can be reached at 510/796-6100 or on the World Wide Web at

-Driver Features
-===============
-
-Configuration Reporting and Testing
------------------------------------
-
- During system initialization, the driver reports extensively on the host
- adapter hardware configuration, including the synchronous transfer parameters
- requested and negotiated with each target device. AutoSCSI settings for
- Synchronous Negotiation, Wide Negotiation, and Disconnect/Reconnect are
- reported for each target device, as well as the status of Tagged Queuing.
- If the same setting is in effect for all target devices, then a single word
- or phrase is used; otherwise, a letter is provided for each target device to
- indicate the individual status. The following examples
- should clarify this reporting format:
-
- Synchronous Negotiation: Ultra
-
- Synchronous negotiation is enabled for all target devices and the host
- adapter will attempt to negotiate for 20.0 mega-transfers/second.
-
- Synchronous Negotiation: Fast
-
- Synchronous negotiation is enabled for all target devices and the host
- adapter will attempt to negotiate for 10.0 mega-transfers/second.
-
- Synchronous Negotiation: Slow
-
- Synchronous negotiation is enabled for all target devices and the host
- adapter will attempt to negotiate for 5.0 mega-transfers/second.
-
- Synchronous Negotiation: Disabled
-
- Synchronous negotiation is disabled and all target devices are limited to
- asynchronous operation.
-
- Synchronous Negotiation: UFSNUUU#UUUUUUUU
-
- Synchronous negotiation to Ultra speed is enabled for target devices 0
- and 4 through 15, to Fast speed for target device 1, to Slow speed for
- target device 2, and is not permitted to target device 3. The host
- adapter's SCSI ID is represented by the "#".
-
- The status of Wide Negotiation, Disconnect/Reconnect, and Tagged Queuing
- are reported as "Enabled", Disabled", or a sequence of "Y" and "N" letters.
-
-Performance Features
---------------------
-
- BusLogic SCSI Host Adapters directly implement SCSI-2 Tagged Queuing, and so
- support has been included in the driver to utilize tagged queuing with any
- target devices that report having the tagged queuing capability. Tagged
- queuing allows for multiple outstanding commands to be issued to each target
- device or logical unit, and can improve I/O performance substantially. In
- addition, BusLogic's Strict Round Robin Mode is used to optimize host adapter
- performance, and scatter/gather I/O can support as many segments as can be
- effectively utilized by the Linux I/O subsystem. Control over the use of
- tagged queuing for each target device as well as individual selection of the
- tagged queue depth is available through driver options provided on the kernel
- command line or at module initialization time. By default, the queue depth
- is determined automatically based on the host adapter's total queue depth and
- the number, type, speed, and capabilities of the target devices found. In
- addition, tagged queuing is automatically disabled whenever the host adapter
- firmware version is known not to implement it correctly, or whenever a tagged
- queue depth of 1 is selected. Tagged queuing is also disabled for individual
- target devices if disconnect/reconnect is disabled for that device.
-
-Robustness Features
--------------------
-
- The driver implements extensive error recovery procedures. When the higher
- level parts of the SCSI subsystem request that a timed out command be reset,
- a selection is made between a full host adapter hard reset and SCSI bus reset
- versus sending a bus device reset message to the individual target device
- based on the recommendation of the SCSI subsystem. Error recovery strategies
- are selectable through driver options individually for each target device,
- and also include sending a bus device reset to the specific target device
- associated with the command being reset, as well as suppressing error
- recovery entirely to avoid perturbing an improperly functioning device. If
- the bus device reset error recovery strategy is selected and sending a bus
- device reset does not restore correct operation, the next command that is
- reset will force a full host adapter hard reset and SCSI bus reset. SCSI bus
- resets caused by other devices and detected by the host adapter are also
- handled by issuing a soft reset to the host adapter and re-initialization.
- Finally, if tagged queuing is active and more than one command reset occurs
- in a 10 minute interval, or if a command reset occurs within the first 10
- minutes of operation, then tagged queuing will be disabled for that target
- device. These error recovery options improve overall system robustness by
- preventing individual errant devices from causing the system as a whole to
- lock up or crash, and thereby allowing a clean shutdown and restart after the
- offending component is removed.
-
-PCI Configuration Support
--------------------------
-
- On PCI systems running kernels compiled with PCI BIOS support enabled, this
- driver will interrogate the PCI configuration space and use the I/O port
- addresses assigned by the system BIOS, rather than the ISA compatible I/O
- port addresses. The ISA compatible I/O port address is then disabled by the
- driver. On PCI systems it is also recommended that the AutoSCSI utility be
- used to disable the ISA compatible I/O port entirely as it is not necessary.
- The ISA compatible I/O port is disabled by default on the BT-948/958/958D.
-
-/proc File System Support
--------------------------
-
- Copies of the host adapter configuration information together with updated
- data transfer and error recovery statistics are available through the
- /proc/scsi/BusLogic/<N> interface.
-
-Shared Interrupts Support
--------------------------
-
- On systems that support shared interrupts, any number of BusLogic Host
- Adapters may share the same interrupt request channel.
-
-

-driver media and documentation that are not provided with bare boards.
-
-
-FlashPoint Installation Notes
-=============================
-
-RAIDPlus Support
-----------------
-
- FlashPoint Host Adapters now include RAIDPlus, Mylex's bootable software
- RAID. RAIDPlus is not supported on Linux, and there are no plans to support
- it. The MD driver in Linux 2.0 provides for concatenation (LINEAR) and
- striping (RAID-0), and support for mirroring (RAID-1), fixed parity (RAID-4),
- and distributed parity (RAID-5) is available separately. The built-in Linux
- RAID support is generally more flexible and is expected to perform better
- than RAIDPlus, so there is little impetus to include RAIDPlus support in the
- BusLogic driver.
-
-Enabling UltraSCSI Transfers
-----------------------------
-
- FlashPoint Host Adapters ship with their configuration set to "Factory
- Default" settings that are conservative and do not allow for UltraSCSI speed
- to be negotiated. This results in fewer problems when these host adapters
- are installed in systems with cabling or termination that is not sufficient
- for UltraSCSI operation, or where existing SCSI devices do not properly
- respond to synchronous transfer negotiation for UltraSCSI speed. AutoSCSI
- may be used to load "Optimum Performance" settings which allow UltraSCSI
- speed to be negotiated with all devices, or UltraSCSI speed can be enabled on
- an individual basis. It is recommended that SCAM be manually disabled after
- the "Optimum Performance" settings are loaded.
-
-
-BT-948/958/958D Installation Notes
-==================================
-
-The BT-948/958/958D PCI Ultra SCSI Host Adapters have some features which may
-require attention in some circumstances when installing Linux.
-
-PCI I/O Port Assignments
-------------------------
-
- When configured to factory default settings, the BT-948/958/958D will only
- recognize the PCI I/O port assignments made by the motherboard's PCI BIOS.
- The BT-948/958/958D will not respond to any of the ISA compatible I/O ports
- that previous BusLogic SCSI Host Adapters respond to. This driver supports
- the PCI I/O port assignments, so this is the preferred configuration.
- However, if the obsolete BusLogic driver must be used for any reason, such as
- a Linux distribution that does not yet use this driver in its boot kernel,
- BusLogic has provided an AutoSCSI configuration option to enable a legacy ISA
- compatible I/O port.
-
- To enable this backward compatibility option, invoke the AutoSCSI utility via
- Ctrl-B at system startup and select "Adapter Configuration", "View/Modify
- Configuration", and then change the "ISA Compatible Port" setting from
- "Disable" to "Primary" or "Alternate". Once this driver has been installed,
- the "ISA Compatible Port" option should be set back to "Disable" to avoid
- possible future I/O port conflicts. The older BT-946C/956C/956CD also have
- this configuration option, but the factory default setting is "Primary".
-
-PCI Slot Scanning Order
------------------------
-
- In systems with multiple BusLogic PCI Host Adapters, the order in which the
- PCI slots are scanned may appear reversed with the BT-948/958/958D as
- compared to the BT-946C/956C/956CD. For booting from a SCSI disk to work
- correctly, it is necessary that the host adapter's BIOS and the kernel agree
- on which disk is the boot device, which requires that they recognize the PCI
- host adapters in the same order. The motherboard's PCI BIOS provides a
- standard way of enumerating the PCI host adapters, which is used by the Linux
- kernel. Some PCI BIOS implementations enumerate the PCI slots in order of
- increasing bus number and device number, while others do so in the opposite
- direction.
-
- Unfortunately, Microsoft decided that Windows 95 would always enumerate the
- PCI slots in order of increasing bus number and device number regardless of
- the PCI BIOS enumeration, and requires that their scheme be supported by the
- host adapter's BIOS to receive Windows 95 certification. Therefore, the
- factory default settings of the BT-948/958/958D enumerate the host adapters
- by increasing bus number and device number. To disable this feature, invoke
- the AutoSCSI utility via Ctrl-B at system startup and select "Adapter
- Configuration", "View/Modify Configuration", press Ctrl-F10, and then change
- the "Use Bus And Device # For PCI Scanning Seq." option to OFF.
-
- This driver will interrogate the setting of the PCI Scanning Sequence option
- so as to recognize the host adapters in the same order as they are enumerated
- by the host adapter's BIOS.
-
-Enabling UltraSCSI Transfers
-----------------------------
-
- The BT-948/958/958D ship with their configuration set to "Factory Default"
- settings that are conservative and do not allow for UltraSCSI speed to be
- negotiated. This results in fewer problems when these host adapters are
- installed in systems with cabling or termination that is not sufficient for
- UltraSCSI operation, or where existing SCSI devices do not properly respond
- to synchronous transfer negotiation for UltraSCSI speed. AutoSCSI may be
- used to load "Optimum Performance" settings which allow UltraSCSI speed to be
- negotiated with all devices, or UltraSCSI speed can be enabled on an
- individual basis. It is recommended that SCAM be manually disabled after the
- "Optimum Performance" settings are loaded.
-
-
-Driver Options
-==============
-
-BusLogic Driver Options may be specified either via the Linux Kernel Command
-Line or via the Loadable Kernel Module Installation Facility. Driver Options
-for multiple host adapters may be specified either by separating the option
-strings by a semicolon, or by specifying multiple "BusLogic=" strings on the
-command line. Individual option specifications for a single host adapter are
-separated by commas. The Probing and Debugging Options apply to all host
-adapters whereas the remaining options apply individually only to the
-selected host adapter.
-
-The BusLogic Driver Probing Options comprise the following:
-
-NoProbe
-
- The "NoProbe" option disables all probing and therefore no BusLogic Host
- Adapters will be detected.
-
-NoProbePCI
-
- The "NoProbePCI" options disables the interrogation of PCI Configuration
- Space and therefore only ISA Multimaster Host Adapters will be detected, as
- well as PCI Multimaster Host Adapters that have their ISA Compatible I/O
- Port set to "Primary" or "Alternate".
-
-NoSortPCI
-
- The "NoSortPCI" option forces PCI MultiMaster Host Adapters to be
- enumerated in the order provided by the PCI BIOS, ignoring any setting of
- the AutoSCSI "Use Bus And Device # For PCI Scanning Seq." option.
-
-MultiMasterFirst
-
- The "MultiMasterFirst" option forces MultiMaster Host Adapters to be probed
- before FlashPoint Host Adapters. By default, if both FlashPoint and PCI
- MultiMaster Host Adapters are present, this driver will probe for
- FlashPoint Host Adapters first unless the BIOS primary disk is controlled
- by the first PCI MultiMaster Host Adapter, in which case MultiMaster Host
- Adapters will be probed first.
-
-FlashPointFirst
-
- The "FlashPointFirst" option forces FlashPoint Host Adapters to be probed
- before MultiMaster Host Adapters.
-
-The BusLogic Driver Tagged Queuing Options allow for explicitly specifying
-the Queue Depth and whether Tagged Queuing is permitted for each Target
-Device (assuming that the Target Device supports Tagged Queuing). The Queue
-Depth is the number of SCSI Commands that are allowed to be concurrently
-presented for execution (either to the Host Adapter or Target Device). Note
-that explicitly enabling Tagged Queuing may lead to problems; the option to
-enable or disable Tagged Queuing is provided primarily to allow disabling
-Tagged Queuing on Target Devices that do not implement it correctly. The
-following options are available:
-
-QueueDepth:<integer>
-
- The "QueueDepth:" or QD:" option specifies the Queue Depth to use for all
- Target Devices that support Tagged Queuing, as well as the maximum Queue
- Depth for devices that do not support Tagged Queuing. If no Queue Depth
- option is provided, the Queue Depth will be determined automatically based
- on the Host Adapter's Total Queue Depth and the number, type, speed, and
- capabilities of the detected Target Devices. Target Devices that
- do not support Tagged Queuing always have their Queue Depth set to
- BusLogic_UntaggedQueueDepth or BusLogic_UntaggedQueueDepthBB, unless a
- lower Queue Depth option is provided. A Queue Depth of 1 automatically
- disables Tagged Queuing.
-
-QueueDepth:[<integer>,<integer>...]
-
- The "QueueDepth:[...]" or "QD:[...]" option specifies the Queue Depth
- individually for each Target Device. If an <integer> is omitted, the
- associated Target Device will have its Queue Depth selected automatically.
-
-TaggedQueuing:Default
-
- The "TaggedQueuing:Default" or "TQ:Default" option permits Tagged Queuing
- based on the firmware version of the BusLogic Host Adapter and based on
- whether the Queue Depth allows queuing multiple commands.
-
-TaggedQueuing:Enable
-
- The "TaggedQueuing:Enable" or "TQ:Enable" option enables Tagged Queuing for
- all Target Devices on this Host Adapter, overriding any limitation that
- would otherwise be imposed based on the Host Adapter firmware version.
-
-TaggedQueuing:Disable
-
- The "TaggedQueuing:Disable" or "TQ:Disable" option disables Tagged Queuing
- for all Target Devices on this Host Adapter.
-
-TaggedQueuing:<Target-Spec>
-
- The "TaggedQueuing:<Target-Spec>" or "TQ:<Target-Spec>" option controls
- Tagged Queuing individually for each Target Device. <Target-Spec> is a
- sequence of "Y", "N", and "X" characters. "Y" enables Tagged Queuing, "N"
- disables Tagged Queuing, and "X" accepts the default based on the firmware
- version. The first character refers to Target Device 0, the second to
- Target Device 1, and so on; if the sequence of "Y", "N", and "X" characters
- does not cover all the Target Devices, unspecified characters are assumed
- to be "X".
-
-The BusLogic Driver Miscellaneous Options comprise the following:
-
-BusSettleTime:<seconds>
-
- The "BusSettleTime:" or "BST:" option specifies the Bus Settle Time in
- seconds. The Bus Settle Time is the amount of time to wait between a Host
- Adapter Hard Reset which initiates a SCSI Bus Reset and issuing any SCSI
- Commands. If unspecified, it defaults to BusLogic_DefaultBusSettleTime.
-
-InhibitTargetInquiry
-
- The "InhibitTargetInquiry" option inhibits the execution of an Inquire
- Target Devices or Inquire Installed Devices command on MultiMaster Host
- Adapters. This may be necessary with some older Target Devices that do not
- respond correctly when Logical Units above 0 are addressed.
-
-The BusLogic Driver Debugging Options comprise the following:
-
-TraceProbe
-
- The "TraceProbe" option enables tracing of Host Adapter Probing.
-
-TraceHardwareReset
-
- The "TraceHardwareReset" option enables tracing of Host Adapter Hardware
- Reset.
-
-TraceConfiguration
-
- The "TraceConfiguration" option enables tracing of Host Adapter
- Configuration.
-
-TraceErrors
-
- The "TraceErrors" option enables tracing of SCSI Commands that return an
- error from the Target Device. The CDB and Sense Data will be printed for
- each SCSI Command that fails.
-

-
- The "Debug" option enables all debugging options.
-
-The following examples demonstrate setting the Queue Depth for Target Devices
-1 and 2 on the first host adapter to 7 and 15, the Queue Depth for all Target
-Devices on the second host adapter to 31, and the Bus Settle Time on the
-second host adapter to 30 seconds.
-
-Linux Kernel Command Line::
-
- linux BusLogic=QueueDepth:[,7,15];QueueDepth:31,BusSettleTime:30

-INSMOD Loadable Kernel Module Installation Facility::
-
- insmod BusLogic.o \
- 'BusLogic="QueueDepth:[,7,15];QueueDepth:31,BusSettleTime:30"'
-
-
-.. Note::
-
- Module Utilities 2.1.71 or later is required for correct parsing
- of driver options containing commas.

-
-Driver Installation
-===================
-
-This distribution was prepared for Linux kernel version 2.0.35, but should be
-compatible with 2.0.4 or any later 2.0 series kernel.
-
-To install the new BusLogic SCSI driver, you may use the following commands,
-replacing "/usr/src" with wherever you keep your Linux kernel source tree::
-
- cd /usr/src
- tar -xvzf BusLogic-2.0.15.tar.gz
- mv README.* LICENSE.* BusLogic.[ch] FlashPoint.c linux/drivers/scsi
- patch -p0 < BusLogic.patch (only for 2.0.33 and below)
- cd linux
- make config
- make zImage
-
-Then install "arch/x86/boot/zImage" as your standard kernel, run lilo if
-appropriate, and reboot.

- MYLEX INTRODUCES LINUX OPERATING SYSTEM SUPPORT FOR ITS
- BUSLOGIC FLASHPOINT LINE OF SCSI HOST ADAPTERS
-
-
- FREMONT, CA, -- October 8, 1996 -- Mylex Corporation has expanded Linux
- operating system support to its BusLogic brand of FlashPoint Ultra SCSI
- host adapters. All of BusLogic's other SCSI host adapters, including the
- MultiMaster line, currently support the Linux operating system. Linux
- drivers and information will be available on October 15th at
- http://sourceforge.net/projects/dandelion/.
-
- "Mylex is committed to supporting the Linux community," says Peter Shambora,
- vice president of marketing for Mylex. "We have supported Linux driver
- development and provided technical support for our host adapters for several
- years, and are pleased to now make our FlashPoint products available to this
- user base."
-
-The Linux Operating System
-==========================
-
-Linux is a freely-distributed implementation of UNIX for Intel x86, Sun
-SPARC, SGI MIPS, Motorola 68k, Digital Alpha AXP and Motorola PowerPC
-machines. It supports a wide range of software, including the X Window
-System, Emacs, and TCP/IP networking. Further information is available at
-http://www.linux.org and http://www.ssc.com/.
-
-FlashPoint Host Adapters
-========================
-
-The FlashPoint family of Ultra SCSI host adapters, designed for workstation
-and file server environments, are available in narrow, wide, dual channel,
-and dual channel wide versions. These adapters feature SeqEngine
-automation technology, which minimizes SCSI command overhead and reduces
-the number of interrupts generated to the CPU.
-
-About Mylex
-===========
-
-Mylex Corporation (NASDAQ/NM SYMBOL: MYLX), founded in 1983, is a leading
-producer of RAID technology and network management products. The company
-produces high performance disk array (RAID) controllers, and complementary
-computer products for network servers, mass storage systems, workstations
-and system boards. Through its wide range of RAID controllers and its

- ANNOUNCEMENT
- BusLogic FlashPoint LT/BT-948 Upgrade Program
- 1 February 1996
-
- ADDITIONAL ANNOUNCEMENT
- BusLogic FlashPoint LW/BT-958 Upgrade Program
- 14 June 1996
-
- Ever since its introduction last October, the BusLogic FlashPoint LT has
- been problematic for members of the Linux community, in that no Linux
- drivers have been available for this new Ultra SCSI product. Despite its
- officially being positioned as a desktop workstation product, and not being
- particularly well suited for a high performance multitasking operating
- system like Linux, the FlashPoint LT has been touted by computer system
- vendors as the latest thing, and has been sold even on many of their high
- end systems, to the exclusion of the older MultiMaster products. This has
- caused grief for many people who inadvertently purchased a system expecting
- that all BusLogic SCSI Host Adapters were supported by Linux, only to
- discover that the FlashPoint was not supported and would not be for quite
- some time, if ever.
-
- After this problem was identified, BusLogic contacted its major OEM
- customers to make sure the BT-946C/956C MultiMaster cards would still be
- made available, and that Linux users who mistakenly ordered systems with
- the FlashPoint would be able to upgrade to the BT-946C. While this helped
- many purchasers of new systems, it was only a partial solution to the
- overall problem of FlashPoint support for Linux users. It did nothing to
- assist the people who initially purchased a FlashPoint for a supported
- operating system and then later decided to run Linux, or those who had
- ended up with a FlashPoint LT, believing it was supported, and were unable
- to return it.
-
- In the middle of December, I asked to meet with BusLogic's senior
- management to discuss the issues related to Linux and free software support
- for the FlashPoint. Rumors of varying accuracy had been circulating
- publicly about BusLogic's attitude toward the Linux community, and I felt
- it was best that these issues be addressed directly. I sent an email
- message after 11pm one evening, and the meeting took place the next
- afternoon. Unfortunately, corporate wheels sometimes grind slowly,
- especially when a company is being acquired, and so it's taken until now
- before the details were completely determined and a public statement could
- be made.
-
- BusLogic is not prepared at this time to release the information necessary
- for third parties to write drivers for the FlashPoint. The only existing
- FlashPoint drivers have been written directly by BusLogic Engineering, and
- there is no FlashPoint documentation sufficiently detailed to allow outside
- developers to write a driver without substantial assistance. While there
- are people at BusLogic who would rather not release the details of the
- FlashPoint architecture at all, that debate has not yet been settled either
- way. In any event, even if documentation were available today it would
- take quite a while for a usable driver to be written, especially since I'm
- not convinced that the effort required would be worthwhile.
-
- However, BusLogic does remain committed to providing a high performance
- SCSI solution for the Linux community, and does not want to see anyone left
- unable to run Linux because they have a Flashpoint LT. Therefore, BusLogic
- has put in place a direct upgrade program to allow any Linux user worldwide
- to trade in their FlashPoint LT for the new BT-948 MultiMaster PCI Ultra
- SCSI Host Adapter. The BT-948 is the Ultra SCSI successor to the BT-946C
- and has all the best features of both the BT-946C and FlashPoint LT,
- including smart termination and a flash PROM for easy firmware updates, and
- is of course compatible with the present Linux driver. The price for this
- upgrade has been set at US $45 plus shipping and handling, and the upgrade
- program will be administered through BusLogic Technical Support, which can
- be reached by electronic mail at techsup@buslogic.com, by Voice at +1 408
- 654-0760, or by FAX at +1 408 492-1542.
-
- As of 14 June 1996, the original BusLogic FlashPoint LT to BT-948 upgrade
- program has now been extended to encompass the FlashPoint LW Wide Ultra
- SCSI Host Adapter. Any Linux user worldwide may trade in their FlashPoint
- LW (BT-950) for a BT-958 MultiMaster PCI Ultra SCSI Host Adapter. The
- price for this upgrade has been set at US $65 plus shipping and handling.
-
- I was a beta test site for the BT-948/958, and versions 1.2.1 and 1.3.1 of
- my BusLogic driver already included latent support for the BT-948/958.
- Additional cosmetic support for the Ultra SCSI MultiMaster cards was added
- subsequent releases. As a result of this cooperative testing process,
- several firmware bugs were found and corrected. My heavily loaded Linux
- test system provided an ideal environment for testing error recovery
- processes that are much more rarely exercised in production systems, but
- are crucial to overall system stability. It was especially convenient
- being able to work directly with their firmware engineer in demonstrating
- the problems under control of the firmware debugging environment; things
- sure have come a long way since the last time I worked on firmware for an
- embedded system. I am presently working on some performance testing and
- expect to have some data to report in the not too distant future.
-
- BusLogic asked me to send this announcement since a large percentage of the
- questions regarding support for the FlashPoint have either been sent to me
- directly via email, or have appeared in the Linux newsgroups in which I
- participate. To summarize, BusLogic is offering Linux users an upgrade
- from the unsupported FlashPoint LT (BT-930) to the supported BT-948 for US
- $45 plus shipping and handling, or from the unsupported FlashPoint LW
- (BT-950) to the supported BT-958 for $65 plus shipping and handling.
- Contact BusLogic Technical Support at techsup@buslogic.com or +1 408
- 654-0760 to take advantage of their offer.

- are used by recent versions of the MultiMaster Firmware, as well as by the

- Units. Since 64 Logical Units are unlikely to be needed in practice, and

- 5 bits simplifies the CCB structure definition, this driver only supports

* [PATCH 5/6] scsi: remove stale BusLogic driver

From: Arnd Bergmann <arnd@arndb.de>
The BusLogic driver is the last remaining driver that relies on the
deprecated bus_to_virt() function, which in turn only works on a few
architectures, and is incompatible with both swiotlb and iommu support.
Before commit 391e2f25601e ("[SCSI] BusLogic: Port driver to 64-bit."),
the driver had a dependency on x86-32, presumably because of this
problem. However, the change introduced another bug that made it still
impossible to use the driver on any 64-bit machine.
This was in turn fixed in commit 56f396146af2 ("scsi: BusLogic: Fix
64-bit system enumeration error for Buslogic"), 8 years later.
The fact that this was found at all is an indication that there are
users, and it seems that Maciej, Matt and Khalid all have access to
this hardware, but if it took eight years to find the problem,
it's likely that nobody actually relies on it.
Remove it as part of the global virt_to_bus()/bus_to_virt() removal.
If anyone is still interested in keeping this driver, the alternative
is to stop it from using bus_to_virt(), possibly along the lines of
how dpt_i2o gets around the same issue.

-Introduction
-============
-
-BusLogic, Inc. designed and manufactured a variety of high performance SCSI
-host adapters which share a common programming interface across a diverse
-collection of bus architectures by virtue of their MultiMaster ASIC technology.
-BusLogic was acquired by Mylex Corporation in February 1996, but the products
-supported by this driver originated under the BusLogic name and so that name is
-retained in the source code and documentation.
-
-This driver supports all present BusLogic MultiMaster Host Adapters, and should
-support any future MultiMaster designs with little or no modification. More
-recently, BusLogic introduced the FlashPoint Host Adapters, which are less
-costly and rely on the host CPU, rather than including an onboard processor.
-Despite not having an onboard CPU, the FlashPoint Host Adapters perform very
-well and have very low command latency. BusLogic has recently provided me with
-the FlashPoint Driver Developer's Kit, which comprises documentation and freely
-redistributable source code for the FlashPoint SCCB Manager. The SCCB Manager
-is the library of code that runs on the host CPU and performs functions
-analogous to the firmware on the MultiMaster Host Adapters. Thanks to their
-having provided the SCCB Manager, this driver now supports the FlashPoint Host
-Adapters as well.
-
-My primary goals in writing this completely new BusLogic driver for Linux are
-to achieve the full performance that BusLogic SCSI Host Adapters and modern
-SCSI peripherals are capable of, and to provide a highly robust driver that can
-be depended upon for high performance mission critical applications. All of
-the major performance features can be configured from the Linux kernel command
-line or at module initialization time, allowing individual installations to
-tune driver performance and error recovery to their particular needs.
-
-The latest information on Linux support for BusLogic SCSI Host Adapters, as
-well as the most recent release of this driver and the latest firmware for the
-BT-948/958/958D, will always be available from my Linux Home Page at URL
-"http://sourceforge.net/projects/dandelion/".
-
-Bug reports should be sent via electronic mail to "lnz@dandelion.com". Please

-Mylex has been an excellent company to work with and I highly recommend their
-products to the Linux community. In November 1995, I was offered the
-opportunity to become a beta test site for their latest MultiMaster product,
-the BT-948 PCI Ultra SCSI Host Adapter, and then again for the BT-958 PCI Wide
-Ultra SCSI Host Adapter in January 1996. This was mutually beneficial since
-Mylex received a degree and kind of testing that their own testing group cannot
-readily achieve, and the Linux community has available high performance host
-adapters that have been well tested with Linux even before being brought to
-market. This relationship has also given me the opportunity to interact
-directly with their technical staff, to understand more about the internal
-workings of their products, and in turn to educate them about the needs and
-potential of the Linux community.
-
-More recently, Mylex has reaffirmed the company's interest in supporting the
-Linux community, and I am now working on a Linux driver for the DAC960 PCI RAID
-Controllers. Mylex's interest and support is greatly appreciated.
-
-Unlike some other vendors, if you contact Mylex Technical Support with a
-problem and are running Linux, they will not tell you that your use of their
-products is unsupported. Their latest product marketing literature even states
-"Mylex SCSI host adapters are compatible with all major operating systems
-including: ... Linux ...".

-Driver Features
-===============
-
-Configuration Reporting and Testing
------------------------------------
-
- During system initialization, the driver reports extensively on the host
- adapter hardware configuration, including the synchronous transfer parameters
- requested and negotiated with each target device. AutoSCSI settings for
- Synchronous Negotiation, Wide Negotiation, and Disconnect/Reconnect are
- reported for each target device, as well as the status of Tagged Queuing.
- If the same setting is in effect for all target devices, then a single word
- or phrase is used; otherwise, a letter is provided for each target device to
- indicate the individual status. The following examples
- should clarify this reporting format:
-
- Synchronous Negotiation: Ultra
-
- Synchronous negotiation is enabled for all target devices and the host
- adapter will attempt to negotiate for 20.0 mega-transfers/second.
-
- Synchronous Negotiation: Fast
-
- Synchronous negotiation is enabled for all target devices and the host
- adapter will attempt to negotiate for 10.0 mega-transfers/second.
-
- Synchronous Negotiation: Slow
-
- Synchronous negotiation is enabled for all target devices and the host
- adapter will attempt to negotiate for 5.0 mega-transfers/second.
-
- Synchronous Negotiation: Disabled
-
- Synchronous negotiation is disabled and all target devices are limited to
- asynchronous operation.
-
- Synchronous Negotiation: UFSNUUU#UUUUUUUU
-
- Synchronous negotiation to Ultra speed is enabled for target devices 0
- and 4 through 15, to Fast speed for target device 1, to Slow speed for
- target device 2, and is not permitted to target device 3. The host
- adapter's SCSI ID is represented by the "#".
-
- The status of Wide Negotiation, Disconnect/Reconnect, and Tagged Queuing
- are reported as "Enabled", Disabled", or a sequence of "Y" and "N" letters.
-
-Performance Features
---------------------
-
- BusLogic SCSI Host Adapters directly implement SCSI-2 Tagged Queuing, and so
- support has been included in the driver to utilize tagged queuing with any
- target devices that report having the tagged queuing capability. Tagged
- queuing allows for multiple outstanding commands to be issued to each target
- device or logical unit, and can improve I/O performance substantially. In
- addition, BusLogic's Strict Round Robin Mode is used to optimize host adapter
- performance, and scatter/gather I/O can support as many segments as can be
- effectively utilized by the Linux I/O subsystem. Control over the use of
- tagged queuing for each target device as well as individual selection of the
- tagged queue depth is available through driver options provided on the kernel
- command line or at module initialization time. By default, the queue depth
- is determined automatically based on the host adapter's total queue depth and
- the number, type, speed, and capabilities of the target devices found. In
- addition, tagged queuing is automatically disabled whenever the host adapter
- firmware version is known not to implement it correctly, or whenever a tagged
- queue depth of 1 is selected. Tagged queuing is also disabled for individual
- target devices if disconnect/reconnect is disabled for that device.
-
-Robustness Features
--------------------
-
- The driver implements extensive error recovery procedures. When the higher
- level parts of the SCSI subsystem request that a timed out command be reset,
- a selection is made between a full host adapter hard reset and SCSI bus reset
- versus sending a bus device reset message to the individual target device
- based on the recommendation of the SCSI subsystem. Error recovery strategies
- are selectable through driver options individually for each target device,
- and also include sending a bus device reset to the specific target device
- associated with the command being reset, as well as suppressing error
- recovery entirely to avoid perturbing an improperly functioning device. If
- the bus device reset error recovery strategy is selected and sending a bus
- device reset does not restore correct operation, the next command that is
- reset will force a full host adapter hard reset and SCSI bus reset. SCSI bus
- resets caused by other devices and detected by the host adapter are also
- handled by issuing a soft reset to the host adapter and re-initialization.
- Finally, if tagged queuing is active and more than one command reset occurs
- in a 10 minute interval, or if a command reset occurs within the first 10
- minutes of operation, then tagged queuing will be disabled for that target
- device. These error recovery options improve overall system robustness by
- preventing individual errant devices from causing the system as a whole to
- lock up or crash, and thereby allowing a clean shutdown and restart after the
- offending component is removed.
-
-PCI Configuration Support
--------------------------
-
- On PCI systems running kernels compiled with PCI BIOS support enabled, this
- driver will interrogate the PCI configuration space and use the I/O port
- addresses assigned by the system BIOS, rather than the ISA compatible I/O
- port addresses. The ISA compatible I/O port address is then disabled by the
- driver. On PCI systems it is also recommended that the AutoSCSI utility be
- used to disable the ISA compatible I/O port entirely as it is not necessary.
- The ISA compatible I/O port is disabled by default on the BT-948/958/958D.
-
-/proc File System Support
--------------------------
-
- Copies of the host adapter configuration information together with updated
- data transfer and error recovery statistics are available through the
- /proc/scsi/BusLogic/<N> interface.
-
-Shared Interrupts Support
--------------------------
-
- On systems that support shared interrupts, any number of BusLogic Host
- Adapters may share the same interrupt request channel.
-
-

-
-
-FlashPoint Installation Notes
-=============================
-
-RAIDPlus Support
-----------------
-
- FlashPoint Host Adapters now include RAIDPlus, Mylex's bootable software
- RAID. RAIDPlus is not supported on Linux, and there are no plans to support
- it. The MD driver in Linux 2.0 provides for concatenation (LINEAR) and
- striping (RAID-0), and support for mirroring (RAID-1), fixed parity (RAID-4),
- and distributed parity (RAID-5) is available separately. The built-in Linux
- RAID support is generally more flexible and is expected to perform better
- than RAIDPlus, so there is little impetus to include RAIDPlus support in the
- BusLogic driver.
-
-Enabling UltraSCSI Transfers
-----------------------------
-
- FlashPoint Host Adapters ship with their configuration set to "Factory
- Default" settings that are conservative and do not allow for UltraSCSI speed
- to be negotiated. This results in fewer problems when these host adapters
- are installed in systems with cabling or termination that is not sufficient
- for UltraSCSI operation, or where existing SCSI devices do not properly
- respond to synchronous transfer negotiation for UltraSCSI speed. AutoSCSI
- may be used to load "Optimum Performance" settings which allow UltraSCSI
- speed to be negotiated with all devices, or UltraSCSI speed can be enabled on
- an individual basis. It is recommended that SCAM be manually disabled after
- the "Optimum Performance" settings are loaded.
-
-
-BT-948/958/958D Installation Notes
-==================================
-
-The BT-948/958/958D PCI Ultra SCSI Host Adapters have some features which may
-require attention in some circumstances when installing Linux.
-
-PCI I/O Port Assignments
-------------------------
-
- When configured to factory default settings, the BT-948/958/958D will only
- recognize the PCI I/O port assignments made by the motherboard's PCI BIOS.
- The BT-948/958/958D will not respond to any of the ISA compatible I/O ports
- that previous BusLogic SCSI Host Adapters respond to. This driver supports
- the PCI I/O port assignments, so this is the preferred configuration.
- However, if the obsolete BusLogic driver must be used for any reason, such as
- a Linux distribution that does not yet use this driver in its boot kernel,
- BusLogic has provided an AutoSCSI configuration option to enable a legacy ISA
- compatible I/O port.
-
- To enable this backward compatibility option, invoke the AutoSCSI utility via
- Ctrl-B at system startup and select "Adapter Configuration", "View/Modify
- Configuration", and then change the "ISA Compatible Port" setting from
- "Disable" to "Primary" or "Alternate". Once this driver has been installed,
- the "ISA Compatible Port" option should be set back to "Disable" to avoid
- possible future I/O port conflicts. The older BT-946C/956C/956CD also have
- this configuration option, but the factory default setting is "Primary".
-
-PCI Slot Scanning Order
------------------------
-
- In systems with multiple BusLogic PCI Host Adapters, the order in which the
- PCI slots are scanned may appear reversed with the BT-948/958/958D as
- compared to the BT-946C/956C/956CD. For booting from a SCSI disk to work
- correctly, it is necessary that the host adapter's BIOS and the kernel agree
- on which disk is the boot device, which requires that they recognize the PCI
- host adapters in the same order. The motherboard's PCI BIOS provides a
- standard way of enumerating the PCI host adapters, which is used by the Linux
- kernel. Some PCI BIOS implementations enumerate the PCI slots in order of
- increasing bus number and device number, while others do so in the opposite
- direction.
-
- Unfortunately, Microsoft decided that Windows 95 would always enumerate the
- PCI slots in order of increasing bus number and device number regardless of
- the PCI BIOS enumeration, and requires that their scheme be supported by the
- host adapter's BIOS to receive Windows 95 certification. Therefore, the
- factory default settings of the BT-948/958/958D enumerate the host adapters
- by increasing bus number and device number. To disable this feature, invoke
- the AutoSCSI utility via Ctrl-B at system startup and select "Adapter
- Configuration", "View/Modify Configuration", press Ctrl-F10, and then change
- the "Use Bus And Device # For PCI Scanning Seq." option to OFF.
-
- This driver will interrogate the setting of the PCI Scanning Sequence option
- so as to recognize the host adapters in the same order as they are enumerated
- by the host adapter's BIOS.
-
-Enabling UltraSCSI Transfers
-----------------------------
-
- The BT-948/958/958D ship with their configuration set to "Factory Default"
- settings that are conservative and do not allow for UltraSCSI speed to be
- negotiated. This results in fewer problems when these host adapters are
- installed in systems with cabling or termination that is not sufficient for
- UltraSCSI operation, or where existing SCSI devices do not properly respond
- to synchronous transfer negotiation for UltraSCSI speed. AutoSCSI may be
- used to load "Optimum Performance" settings which allow UltraSCSI speed to be
- negotiated with all devices, or UltraSCSI speed can be enabled on an
- individual basis. It is recommended that SCAM be manually disabled after the
- "Optimum Performance" settings are loaded.
-
-
-Driver Options
-==============
-
-BusLogic Driver Options may be specified either via the Linux Kernel Command
-Line or via the Loadable Kernel Module Installation Facility. Driver Options
-for multiple host adapters may be specified either by separating the option
-strings by a semicolon, or by specifying multiple "BusLogic=" strings on the
-command line. Individual option specifications for a single host adapter are
-separated by commas. The Probing and Debugging Options apply to all host
-adapters whereas the remaining options apply individually only to the
-selected host adapter.
-
-The BusLogic Driver Probing Options comprise the following:
-
-NoProbe
-
- The "NoProbe" option disables all probing and therefore no BusLogic Host
- Adapters will be detected.
-
-NoProbePCI
-
- The "NoProbePCI" options disables the interrogation of PCI Configuration
- Space and therefore only ISA Multimaster Host Adapters will be detected, as
- well as PCI Multimaster Host Adapters that have their ISA Compatible I/O
- Port set to "Primary" or "Alternate".
-
-NoSortPCI
-
- The "NoSortPCI" option forces PCI MultiMaster Host Adapters to be
- enumerated in the order provided by the PCI BIOS, ignoring any setting of
- the AutoSCSI "Use Bus And Device # For PCI Scanning Seq." option.
-
-MultiMasterFirst
-
- The "MultiMasterFirst" option forces MultiMaster Host Adapters to be probed
- before FlashPoint Host Adapters. By default, if both FlashPoint and PCI
- MultiMaster Host Adapters are present, this driver will probe for
- FlashPoint Host Adapters first unless the BIOS primary disk is controlled
- by the first PCI MultiMaster Host Adapter, in which case MultiMaster Host
- Adapters will be probed first.
-
-FlashPointFirst
-
- The "FlashPointFirst" option forces FlashPoint Host Adapters to be probed
- before MultiMaster Host Adapters.
-
-The BusLogic Driver Tagged Queuing Options allow for explicitly specifying
-the Queue Depth and whether Tagged Queuing is permitted for each Target
-Device (assuming that the Target Device supports Tagged Queuing). The Queue
-Depth is the number of SCSI Commands that are allowed to be concurrently
-presented for execution (either to the Host Adapter or Target Device). Note
-that explicitly enabling Tagged Queuing may lead to problems; the option to
-enable or disable Tagged Queuing is provided primarily to allow disabling
-Tagged Queuing on Target Devices that do not implement it correctly. The
-following options are available:
-
-QueueDepth:<integer>
-
- The "QueueDepth:" or QD:" option specifies the Queue Depth to use for all
- Target Devices that support Tagged Queuing, as well as the maximum Queue
- Depth for devices that do not support Tagged Queuing. If no Queue Depth
- option is provided, the Queue Depth will be determined automatically based
- on the Host Adapter's Total Queue Depth and the number, type, speed, and
- capabilities of the detected Target Devices. Target Devices that
- do not support Tagged Queuing always have their Queue Depth set to
- BusLogic_UntaggedQueueDepth or BusLogic_UntaggedQueueDepthBB, unless a
- lower Queue Depth option is provided. A Queue Depth of 1 automatically
- disables Tagged Queuing.
-
-QueueDepth:[<integer>,<integer>...]
-
- The "QueueDepth:[...]" or "QD:[...]" option specifies the Queue Depth
- individually for each Target Device. If an <integer> is omitted, the
- associated Target Device will have its Queue Depth selected automatically.
-
-TaggedQueuing:Default
-
- The "TaggedQueuing:Default" or "TQ:Default" option permits Tagged Queuing
- based on the firmware version of the BusLogic Host Adapter and based on
- whether the Queue Depth allows queuing multiple commands.
-
-TaggedQueuing:Enable
-
- The "TaggedQueuing:Enable" or "TQ:Enable" option enables Tagged Queuing for
- all Target Devices on this Host Adapter, overriding any limitation that
- would otherwise be imposed based on the Host Adapter firmware version.
-
-TaggedQueuing:Disable
-
- The "TaggedQueuing:Disable" or "TQ:Disable" option disables Tagged Queuing
- for all Target Devices on this Host Adapter.
-
-TaggedQueuing:<Target-Spec>
-
- The "TaggedQueuing:<Target-Spec>" or "TQ:<Target-Spec>" option controls
- Tagged Queuing individually for each Target Device. <Target-Spec> is a
- sequence of "Y", "N", and "X" characters. "Y" enables Tagged Queuing, "N"
- disables Tagged Queuing, and "X" accepts the default based on the firmware
- version. The first character refers to Target Device 0, the second to
- Target Device 1, and so on; if the sequence of "Y", "N", and "X" characters
- does not cover all the Target Devices, unspecified characters are assumed
- to be "X".
-
-The BusLogic Driver Miscellaneous Options comprise the following:
-
-BusSettleTime:<seconds>
-
- The "BusSettleTime:" or "BST:" option specifies the Bus Settle Time in
- seconds. The Bus Settle Time is the amount of time to wait between a Host
- Adapter Hard Reset which initiates a SCSI Bus Reset and issuing any SCSI
- Commands. If unspecified, it defaults to BusLogic_DefaultBusSettleTime.
-
-InhibitTargetInquiry
-
- The "InhibitTargetInquiry" option inhibits the execution of an Inquire
- Target Devices or Inquire Installed Devices command on MultiMaster Host
- Adapters. This may be necessary with some older Target Devices that do not
- respond correctly when Logical Units above 0 are addressed.
-
-The BusLogic Driver Debugging Options comprise the following:
-
-TraceProbe
-
- The "TraceProbe" option enables tracing of Host Adapter Probing.
-
-TraceHardwareReset
-
- The "TraceHardwareReset" option enables tracing of Host Adapter Hardware
- Reset.
-
-TraceConfiguration
-
- The "TraceConfiguration" option enables tracing of Host Adapter
- Configuration.
-
-TraceErrors
-
- The "TraceErrors" option enables tracing of SCSI Commands that return an
- error from the Target Device. The CDB and Sense Data will be printed for
- each SCSI Command that fails.
-
-Debug
-
- The "Debug" option enables all debugging options.
-
-The following examples demonstrate setting the Queue Depth for Target Devices
-1 and 2 on the first host adapter to 7 and 15, the Queue Depth for all Target
-Devices on the second host adapter to 31, and the Bus Settle Time on the
-second host adapter to 30 seconds.
-
-Linux Kernel Command Line::
-
- linux BusLogic=QueueDepth:[,7,15];QueueDepth:31,BusSettleTime:30
-
-LILO Linux Boot Loader (in /etc/lilo.conf)::
-
- append = "BusLogic=QueueDepth:[,7,15];QueueDepth:31,BusSettleTime:30"
-
-INSMOD Loadable Kernel Module Installation Facility::
-
- insmod BusLogic.o \
- 'BusLogic="QueueDepth:[,7,15];QueueDepth:31,BusSettleTime:30"'
-
-
-.. Note::
-
- Module Utilities 2.1.71 or later is required for correct parsing
- of driver options containing commas.
-
-
-Driver Installation
-===================
-
-This distribution was prepared for Linux kernel version 2.0.35, but should be
-compatible with 2.0.4 or any later 2.0 series kernel.
-
-To install the new BusLogic SCSI driver, you may use the following commands,
-replacing "/usr/src" with wherever you keep your Linux kernel source tree::
-
- cd /usr/src
- tar -xvzf BusLogic-2.0.15.tar.gz
- mv README.* LICENSE.* BusLogic.[ch] FlashPoint.c linux/drivers/scsi
- patch -p0 < BusLogic.patch (only for 2.0.33 and below)
- cd linux
- make config
- make zImage
-
-Then install "arch/x86/boot/zImage" as your standard kernel, run lilo if
-appropriate, and reboot.
-

- ANNOUNCEMENT
- BusLogic FlashPoint LT/BT-948 Upgrade Program
- 1 February 1996
-
- ADDITIONAL ANNOUNCEMENT
- BusLogic FlashPoint LW/BT-958 Upgrade Program
- 14 June 1996
-
- Ever since its introduction last October, the BusLogic FlashPoint LT has
- been problematic for members of the Linux community, in that no Linux
- drivers have been available for this new Ultra SCSI product. Despite its
- officially being positioned as a desktop workstation product, and not being
- particularly well suited for a high performance multitasking operating
- system like Linux, the FlashPoint LT has been touted by computer system
- vendors as the latest thing, and has been sold even on many of their high
- end systems, to the exclusion of the older MultiMaster products. This has
- caused grief for many people who inadvertently purchased a system expecting
- that all BusLogic SCSI Host Adapters were supported by Linux, only to
- discover that the FlashPoint was not supported and would not be for quite
- some time, if ever.
-
- After this problem was identified, BusLogic contacted its major OEM
- customers to make sure the BT-946C/956C MultiMaster cards would still be
- made available, and that Linux users who mistakenly ordered systems with
- the FlashPoint would be able to upgrade to the BT-946C. While this helped
- many purchasers of new systems, it was only a partial solution to the
- overall problem of FlashPoint support for Linux users. It did nothing to
- assist the people who initially purchased a FlashPoint for a supported
- operating system and then later decided to run Linux, or those who had
- ended up with a FlashPoint LT, believing it was supported, and were unable
- to return it.
-
- In the middle of December, I asked to meet with BusLogic's senior
- management to discuss the issues related to Linux and free software support
- for the FlashPoint. Rumors of varying accuracy had been circulating
- publicly about BusLogic's attitude toward the Linux community, and I felt
- it was best that these issues be addressed directly. I sent an email
- message after 11pm one evening, and the meeting took place the next
- afternoon. Unfortunately, corporate wheels sometimes grind slowly,
- especially when a company is being acquired, and so it's taken until now
- before the details were completely determined and a public statement could
- be made.
-
- BusLogic is not prepared at this time to release the information necessary
- for third parties to write drivers for the FlashPoint. The only existing
- FlashPoint drivers have been written directly by BusLogic Engineering, and
- there is no FlashPoint documentation sufficiently detailed to allow outside
- developers to write a driver without substantial assistance. While there
- are people at BusLogic who would rather not release the details of the
- FlashPoint architecture at all, that debate has not yet been settled either
- way. In any event, even if documentation were available today it would
- take quite a while for a usable driver to be written, especially since I'm
- not convinced that the effort required would be worthwhile.
-
- However, BusLogic does remain committed to providing a high performance
- SCSI solution for the Linux community, and does not want to see anyone left
- unable to run Linux because they have a Flashpoint LT. Therefore, BusLogic
- has put in place a direct upgrade program to allow any Linux user worldwide
- to trade in their FlashPoint LT for the new BT-948 MultiMaster PCI Ultra
- SCSI Host Adapter. The BT-948 is the Ultra SCSI successor to the BT-946C
- and has all the best features of both the BT-946C and FlashPoint LT,
- including smart termination and a flash PROM for easy firmware updates, and
- is of course compatible with the present Linux driver. The price for this
- upgrade has been set at US $45 plus shipping and handling, and the upgrade
- program will be administered through BusLogic Technical Support, which can
- be reached by electronic mail at techsup@buslogic.com, by Voice at +1 408
- 654-0760, or by FAX at +1 408 492-1542.
-
- As of 14 June 1996, the original BusLogic FlashPoint LT to BT-948 upgrade
- program has now been extended to encompass the FlashPoint LW Wide Ultra
- SCSI Host Adapter. Any Linux user worldwide may trade in their FlashPoint
- LW (BT-950) for a BT-958 MultiMaster PCI Ultra SCSI Host Adapter. The
- price for this upgrade has been set at US $65 plus shipping and handling.
-
- I was a beta test site for the BT-948/958, and versions 1.2.1 and 1.3.1 of
- my BusLogic driver already included latent support for the BT-948/958.
- Additional cosmetic support for the Ultra SCSI MultiMaster cards was added
- subsequent releases. As a result of this cooperative testing process,
- several firmware bugs were found and corrected. My heavily loaded Linux
- test system provided an ideal environment for testing error recovery
- processes that are much more rarely exercised in production systems, but
- are crucial to overall system stability. It was especially convenient
- being able to work directly with their firmware engineer in demonstrating
- the problems under control of the firmware debugging environment; things
- sure have come a long way since the last time I worked on firmware for an
- embedded system. I am presently working on some performance testing and
- expect to have some data to report in the not too distant future.
-
- BusLogic asked me to send this announcement since a large percentage of the
- questions regarding support for the FlashPoint have either been sent to me
- directly via email, or have appeared in the Linux newsgroups in which I
- participate. To summarize, BusLogic is offering Linux users an upgrade
- from the unsupported FlashPoint LT (BT-930) to the supported BT-948 for US
- $45 plus shipping and handling, or from the unsupported FlashPoint LW
- (BT-950) to the supported BT-958 for $65 plus shipping and handling.
- Contact BusLogic Technical Support at techsup@buslogic.com or +1 408
- 654-0760 to take advantage of their offer.

From: Arnd Bergmann <arnd-r2nGTMty4D4@public.gmane.org>
The BusLogic driver is the last remaining driver that relies on the
deprecated bus_to_virt() function, which in turn only works on a few
architectures, and is incompatible with both swiotlb and iommu support.
Before commit 391e2f25601e ("[SCSI] BusLogic: Port driver to 64-bit."),
the driver had a dependency on x86-32, presumably because of this
problem. However, the change introduced another bug that made it still
impossible to use the driver on any 64-bit machine.
This was in turn fixed in commit 56f396146af2 ("scsi: BusLogic: Fix
64-bit system enumeration error for Buslogic"), 8 years later.
The fact that this was found at all is an indication that there are
users, and it seems that Maciej, Matt and Khalid all have access to
this hardware, but if it took eight years to find the problem,
it's likely that nobody actually relies on it.
Remove it as part of the global virt_to_bus()/bus_to_virt() removal.
If anyone is still interested in keeping this driver, the alternative
is to stop it from using bus_to_virt(), possibly along the lines of
how dpt_i2o gets around the same issue.

-Introduction
-============
-
-BusLogic, Inc. designed and manufactured a variety of high performance SCSI
-host adapters which share a common programming interface across a diverse
-collection of bus architectures by virtue of their MultiMaster ASIC technology.
-BusLogic was acquired by Mylex Corporation in February 1996, but the products
-supported by this driver originated under the BusLogic name and so that name is
-retained in the source code and documentation.
-
-This driver supports all present BusLogic MultiMaster Host Adapters, and should
-support any future MultiMaster designs with little or no modification. More
-recently, BusLogic introduced the FlashPoint Host Adapters, which are less
-costly and rely on the host CPU, rather than including an onboard processor.
-Despite not having an onboard CPU, the FlashPoint Host Adapters perform very
-well and have very low command latency. BusLogic has recently provided me with
-the FlashPoint Driver Developer's Kit, which comprises documentation and freely
-redistributable source code for the FlashPoint SCCB Manager. The SCCB Manager
-is the library of code that runs on the host CPU and performs functions
-analogous to the firmware on the MultiMaster Host Adapters. Thanks to their
-having provided the SCCB Manager, this driver now supports the FlashPoint Host
-Adapters as well.
-
-My primary goals in writing this completely new BusLogic driver for Linux are
-to achieve the full performance that BusLogic SCSI Host Adapters and modern
-SCSI peripherals are capable of, and to provide a highly robust driver that can
-be depended upon for high performance mission critical applications. All of
-the major performance features can be configured from the Linux kernel command
-line or at module initialization time, allowing individual installations to
-tune driver performance and error recovery to their particular needs.
-
-The latest information on Linux support for BusLogic SCSI Host Adapters, as
-well as the most recent release of this driver and the latest firmware for the
-BT-948/958/958D, will always be available from my Linux Home Page at URL
-"http://sourceforge.net/projects/dandelion/".
-
-Bug reports should be sent via electronic mail to "lnz-Jy8Lyc2Oj6yaMJb+Lgu22Q@public.gmane.org". Please
-include with the bug report the complete configuration messages reported by the
-driver and SCSI subsystem at startup, along with any subsequent system messages
-relevant to SCSI operations, and a detailed description of your system's
-hardware configuration.
-
-Mylex has been an excellent company to work with and I highly recommend their
-products to the Linux community. In November 1995, I was offered the
-opportunity to become a beta test site for their latest MultiMaster product,
-the BT-948 PCI Ultra SCSI Host Adapter, and then again for the BT-958 PCI Wide
-Ultra SCSI Host Adapter in January 1996. This was mutually beneficial since
-Mylex received a degree and kind of testing that their own testing group cannot
-readily achieve, and the Linux community has available high performance host
-adapters that have been well tested with Linux even before being brought to
-market. This relationship has also given me the opportunity to interact
-directly with their technical staff, to understand more about the internal
-workings of their products, and in turn to educate them about the needs and
-potential of the Linux community.
-
-More recently, Mylex has reaffirmed the company's interest in supporting the
-Linux community, and I am now working on a Linux driver for the DAC960 PCI RAID
-Controllers. Mylex's interest and support is greatly appreciated.
-
-Unlike some other vendors, if you contact Mylex Technical Support with a
-problem and are running Linux, they will not tell you that your use of their
-products is unsupported. Their latest product marketing literature even states
-"Mylex SCSI host adapters are compatible with all major operating systems
-including: ... Linux ...".

-Driver Features
-===============
-
-Configuration Reporting and Testing
------------------------------------
-
- During system initialization, the driver reports extensively on the host
- adapter hardware configuration, including the synchronous transfer parameters
- requested and negotiated with each target device. AutoSCSI settings for
- Synchronous Negotiation, Wide Negotiation, and Disconnect/Reconnect are
- reported for each target device, as well as the status of Tagged Queuing.
- If the same setting is in effect for all target devices, then a single word
- or phrase is used; otherwise, a letter is provided for each target device to
- indicate the individual status. The following examples
- should clarify this reporting format:
-
- Synchronous Negotiation: Ultra
-
- Synchronous negotiation is enabled for all target devices and the host
- adapter will attempt to negotiate for 20.0 mega-transfers/second.
-
- Synchronous Negotiation: Fast
-
- Synchronous negotiation is enabled for all target devices and the host
- adapter will attempt to negotiate for 10.0 mega-transfers/second.
-
- Synchronous Negotiation: Slow
-
- Synchronous negotiation is enabled for all target devices and the host
- adapter will attempt to negotiate for 5.0 mega-transfers/second.
-
- Synchronous Negotiation: Disabled
-
- Synchronous negotiation is disabled and all target devices are limited to
- asynchronous operation.
-
- Synchronous Negotiation: UFSNUUU#UUUUUUUU
-
- Synchronous negotiation to Ultra speed is enabled for target devices 0
- and 4 through 15, to Fast speed for target device 1, to Slow speed for
- target device 2, and is not permitted to target device 3. The host
- adapter's SCSI ID is represented by the "#".
-
- The status of Wide Negotiation, Disconnect/Reconnect, and Tagged Queuing
- are reported as "Enabled", Disabled", or a sequence of "Y" and "N" letters.
-
-Performance Features
---------------------
-
- BusLogic SCSI Host Adapters directly implement SCSI-2 Tagged Queuing, and so
- support has been included in the driver to utilize tagged queuing with any
- target devices that report having the tagged queuing capability. Tagged
- queuing allows for multiple outstanding commands to be issued to each target
- device or logical unit, and can improve I/O performance substantially. In
- addition, BusLogic's Strict Round Robin Mode is used to optimize host adapter
- performance, and scatter/gather I/O can support as many segments as can be
- effectively utilized by the Linux I/O subsystem. Control over the use of
- tagged queuing for each target device as well as individual selection of the
- tagged queue depth is available through driver options provided on the kernel
- command line or at module initialization time. By default, the queue depth
- is determined automatically based on the host adapter's total queue depth and
- the number, type, speed, and capabilities of the target devices found. In
- addition, tagged queuing is automatically disabled whenever the host adapter
- firmware version is known not to implement it correctly, or whenever a tagged
- queue depth of 1 is selected. Tagged queuing is also disabled for individual
- target devices if disconnect/reconnect is disabled for that device.
-
-Robustness Features
--------------------
-
- The driver implements extensive error recovery procedures. When the higher
- level parts of the SCSI subsystem request that a timed out command be reset,
- a selection is made between a full host adapter hard reset and SCSI bus reset
- versus sending a bus device reset message to the individual target device
- based on the recommendation of the SCSI subsystem. Error recovery strategies
- are selectable through driver options individually for each target device,
- and also include sending a bus device reset to the specific target device
- associated with the command being reset, as well as suppressing error
- recovery entirely to avoid perturbing an improperly functioning device. If
- the bus device reset error recovery strategy is selected and sending a bus
- device reset does not restore correct operation, the next command that is
- reset will force a full host adapter hard reset and SCSI bus reset. SCSI bus
- resets caused by other devices and detected by the host adapter are also
- handled by issuing a soft reset to the host adapter and re-initialization.
- Finally, if tagged queuing is active and more than one command reset occurs
- in a 10 minute interval, or if a command reset occurs within the first 10
- minutes of operation, then tagged queuing will be disabled for that target
- device. These error recovery options improve overall system robustness by
- preventing individual errant devices from causing the system as a whole to
- lock up or crash, and thereby allowing a clean shutdown and restart after the
- offending component is removed.
-
-PCI Configuration Support
--------------------------
-
- On PCI systems running kernels compiled with PCI BIOS support enabled, this
- driver will interrogate the PCI configuration space and use the I/O port
- addresses assigned by the system BIOS, rather than the ISA compatible I/O
- port addresses. The ISA compatible I/O port address is then disabled by the
- driver. On PCI systems it is also recommended that the AutoSCSI utility be
- used to disable the ISA compatible I/O port entirely as it is not necessary.
- The ISA compatible I/O port is disabled by default on the BT-948/958/958D.
-
-/proc File System Support
--------------------------
-
- Copies of the host adapter configuration information together with updated
- data transfer and error recovery statistics are available through the
- /proc/scsi/BusLogic/<N> interface.
-
-Shared Interrupts Support
--------------------------
-
- On systems that support shared interrupts, any number of BusLogic Host
- Adapters may share the same interrupt request channel.
-

-driver media and documentation that are not provided with bare boards.
-
-
-FlashPoint Installation Notes
-=============================
-
-RAIDPlus Support
-----------------
-
- FlashPoint Host Adapters now include RAIDPlus, Mylex's bootable software
- RAID. RAIDPlus is not supported on Linux, and there are no plans to support
- it. The MD driver in Linux 2.0 provides for concatenation (LINEAR) and
- striping (RAID-0), and support for mirroring (RAID-1), fixed parity (RAID-4),
- and distributed parity (RAID-5) is available separately. The built-in Linux
- RAID support is generally more flexible and is expected to perform better
- than RAIDPlus, so there is little impetus to include RAIDPlus support in the
- BusLogic driver.
-
-Enabling UltraSCSI Transfers
-----------------------------
-
- FlashPoint Host Adapters ship with their configuration set to "Factory
- Default" settings that are conservative and do not allow for UltraSCSI speed
- to be negotiated. This results in fewer problems when these host adapters
- are installed in systems with cabling or termination that is not sufficient
- for UltraSCSI operation, or where existing SCSI devices do not properly
- respond to synchronous transfer negotiation for UltraSCSI speed. AutoSCSI
- may be used to load "Optimum Performance" settings which allow UltraSCSI
- speed to be negotiated with all devices, or UltraSCSI speed can be enabled on
- an individual basis. It is recommended that SCAM be manually disabled after
- the "Optimum Performance" settings are loaded.
-
-
-BT-948/958/958D Installation Notes
-==================================
-
-The BT-948/958/958D PCI Ultra SCSI Host Adapters have some features which may
-require attention in some circumstances when installing Linux.
-
-PCI I/O Port Assignments
-------------------------
-
- When configured to factory default settings, the BT-948/958/958D will only
- recognize the PCI I/O port assignments made by the motherboard's PCI BIOS.
- The BT-948/958/958D will not respond to any of the ISA compatible I/O ports
- that previous BusLogic SCSI Host Adapters respond to. This driver supports
- the PCI I/O port assignments, so this is the preferred configuration.
- However, if the obsolete BusLogic driver must be used for any reason, such as
- a Linux distribution that does not yet use this driver in its boot kernel,
- BusLogic has provided an AutoSCSI configuration option to enable a legacy ISA
- compatible I/O port.
-
- To enable this backward compatibility option, invoke the AutoSCSI utility via
- Ctrl-B at system startup and select "Adapter Configuration", "View/Modify
- Configuration", and then change the "ISA Compatible Port" setting from
- "Disable" to "Primary" or "Alternate". Once this driver has been installed,
- the "ISA Compatible Port" option should be set back to "Disable" to avoid
- possible future I/O port conflicts. The older BT-946C/956C/956CD also have
- this configuration option, but the factory default setting is "Primary".
-
-PCI Slot Scanning Order
------------------------
-
- In systems with multiple BusLogic PCI Host Adapters, the order in which the
- PCI slots are scanned may appear reversed with the BT-948/958/958D as
- compared to the BT-946C/956C/956CD. For booting from a SCSI disk to work
- correctly, it is necessary that the host adapter's BIOS and the kernel agree
- on which disk is the boot device, which requires that they recognize the PCI
- host adapters in the same order. The motherboard's PCI BIOS provides a
- standard way of enumerating the PCI host adapters, which is used by the Linux
- kernel. Some PCI BIOS implementations enumerate the PCI slots in order of
- increasing bus number and device number, while others do so in the opposite
- direction.
-
- Unfortunately, Microsoft decided that Windows 95 would always enumerate the
- PCI slots in order of increasing bus number and device number regardless of
- the PCI BIOS enumeration, and requires that their scheme be supported by the
- host adapter's BIOS to receive Windows 95 certification. Therefore, the
- factory default settings of the BT-948/958/958D enumerate the host adapters
- by increasing bus number and device number. To disable this feature, invoke
- the AutoSCSI utility via Ctrl-B at system startup and select "Adapter
- Configuration", "View/Modify Configuration", press Ctrl-F10, and then change
- the "Use Bus And Device # For PCI Scanning Seq." option to OFF.
-
- This driver will interrogate the setting of the PCI Scanning Sequence option
- so as to recognize the host adapters in the same order as they are enumerated
- by the host adapter's BIOS.
-
-Enabling UltraSCSI Transfers
-----------------------------
-
- The BT-948/958/958D ship with their configuration set to "Factory Default"
- settings that are conservative and do not allow for UltraSCSI speed to be
- negotiated. This results in fewer problems when these host adapters are
- installed in systems with cabling or termination that is not sufficient for
- UltraSCSI operation, or where existing SCSI devices do not properly respond
- to synchronous transfer negotiation for UltraSCSI speed. AutoSCSI may be
- used to load "Optimum Performance" settings which allow UltraSCSI speed to be
- negotiated with all devices, or UltraSCSI speed can be enabled on an
- individual basis. It is recommended that SCAM be manually disabled after the
- "Optimum Performance" settings are loaded.
-
-
-Driver Options
-==============
-
-BusLogic Driver Options may be specified either via the Linux Kernel Command
-Line or via the Loadable Kernel Module Installation Facility. Driver Options
-for multiple host adapters may be specified either by separating the option
-strings by a semicolon, or by specifying multiple "BusLogic=" strings on the
-command line. Individual option specifications for a single host adapter are
-separated by commas. The Probing and Debugging Options apply to all host
-adapters whereas the remaining options apply individually only to the
-selected host adapter.
-
-The BusLogic Driver Probing Options comprise the following:
-
-NoProbe
-
- The "NoProbe" option disables all probing and therefore no BusLogic Host
- Adapters will be detected.
-
-NoProbePCI
-
- The "NoProbePCI" options disables the interrogation of PCI Configuration
- Space and therefore only ISA Multimaster Host Adapters will be detected, as
- well as PCI Multimaster Host Adapters that have their ISA Compatible I/O
- Port set to "Primary" or "Alternate".
-
-NoSortPCI
-
- The "NoSortPCI" option forces PCI MultiMaster Host Adapters to be
- enumerated in the order provided by the PCI BIOS, ignoring any setting of
- the AutoSCSI "Use Bus And Device # For PCI Scanning Seq." option.
-
-MultiMasterFirst
-
- The "MultiMasterFirst" option forces MultiMaster Host Adapters to be probed
- before FlashPoint Host Adapters. By default, if both FlashPoint and PCI
- MultiMaster Host Adapters are present, this driver will probe for
- FlashPoint Host Adapters first unless the BIOS primary disk is controlled
- by the first PCI MultiMaster Host Adapter, in which case MultiMaster Host
- Adapters will be probed first.
-
-FlashPointFirst
-
- The "FlashPointFirst" option forces FlashPoint Host Adapters to be probed
- before MultiMaster Host Adapters.
-
-The BusLogic Driver Tagged Queuing Options allow for explicitly specifying
-the Queue Depth and whether Tagged Queuing is permitted for each Target
-Device (assuming that the Target Device supports Tagged Queuing). The Queue
-Depth is the number of SCSI Commands that are allowed to be concurrently
-presented for execution (either to the Host Adapter or Target Device). Note
-that explicitly enabling Tagged Queuing may lead to problems; the option to
-enable or disable Tagged Queuing is provided primarily to allow disabling
-Tagged Queuing on Target Devices that do not implement it correctly. The
-following options are available:
-
-QueueDepth:<integer>
-
- The "QueueDepth:" or QD:" option specifies the Queue Depth to use for all
- Target Devices that support Tagged Queuing, as well as the maximum Queue
- Depth for devices that do not support Tagged Queuing. If no Queue Depth
- option is provided, the Queue Depth will be determined automatically based
- on the Host Adapter's Total Queue Depth and the number, type, speed, and
- capabilities of the detected Target Devices. Target Devices that
- do not support Tagged Queuing always have their Queue Depth set to
- BusLogic_UntaggedQueueDepth or BusLogic_UntaggedQueueDepthBB, unless a
- lower Queue Depth option is provided. A Queue Depth of 1 automatically
- disables Tagged Queuing.
-
-QueueDepth:[<integer>,<integer>...]
-
- The "QueueDepth:[...]" or "QD:[...]" option specifies the Queue Depth
- individually for each Target Device. If an <integer> is omitted, the
- associated Target Device will have its Queue Depth selected automatically.
-
-TaggedQueuing:Default
-
- The "TaggedQueuing:Default" or "TQ:Default" option permits Tagged Queuing
- based on the firmware version of the BusLogic Host Adapter and based on
- whether the Queue Depth allows queuing multiple commands.
-
-TaggedQueuing:Enable
-
- The "TaggedQueuing:Enable" or "TQ:Enable" option enables Tagged Queuing for
- all Target Devices on this Host Adapter, overriding any limitation that
- would otherwise be imposed based on the Host Adapter firmware version.
-
-TaggedQueuing:Disable
-
- The "TaggedQueuing:Disable" or "TQ:Disable" option disables Tagged Queuing
- for all Target Devices on this Host Adapter.
-
-TaggedQueuing:<Target-Spec>
-
- The "TaggedQueuing:<Target-Spec>" or "TQ:<Target-Spec>" option controls
- Tagged Queuing individually for each Target Device. <Target-Spec> is a
- sequence of "Y", "N", and "X" characters. "Y" enables Tagged Queuing, "N"
- disables Tagged Queuing, and "X" accepts the default based on the firmware
- version. The first character refers to Target Device 0, the second to
- Target Device 1, and so on; if the sequence of "Y", "N", and "X" characters
- does not cover all the Target Devices, unspecified characters are assumed
- to be "X".
-
-The BusLogic Driver Miscellaneous Options comprise the following:
-
-BusSettleTime:<seconds>
-
- The "BusSettleTime:" or "BST:" option specifies the Bus Settle Time in
- seconds. The Bus Settle Time is the amount of time to wait between a Host
- Adapter Hard Reset which initiates a SCSI Bus Reset and issuing any SCSI
- Commands. If unspecified, it defaults to BusLogic_DefaultBusSettleTime.
-
-InhibitTargetInquiry
-
- The "InhibitTargetInquiry" option inhibits the execution of an Inquire
- Target Devices or Inquire Installed Devices command on MultiMaster Host
- Adapters. This may be necessary with some older Target Devices that do not
- respond correctly when Logical Units above 0 are addressed.
-
-The BusLogic Driver Debugging Options comprise the following:
-
-TraceProbe
-
- The "TraceProbe" option enables tracing of Host Adapter Probing.
-
-TraceHardwareReset
-
- The "TraceHardwareReset" option enables tracing of Host Adapter Hardware
- Reset.
-
-TraceConfiguration
-
- The "TraceConfiguration" option enables tracing of Host Adapter
- Configuration.
-
-TraceErrors
-
- The "TraceErrors" option enables tracing of SCSI Commands that return an
- error from the Target Device. The CDB and Sense Data will be printed for
- each SCSI Command that fails.
-
-Debug
-
- The "Debug" option enables all debugging options.
-
-The following examples demonstrate setting the Queue Depth for Target Devices
-1 and 2 on the first host adapter to 7 and 15, the Queue Depth for all Target
-Devices on the second host adapter to 31, and the Bus Settle Time on the
-second host adapter to 30 seconds.
-
-Linux Kernel Command Line::
-
- linux BusLogic=QueueDepth:[,7,15];QueueDepth:31,BusSettleTime:30
-
-LILO Linux Boot Loader (in /etc/lilo.conf)::
-
- append = "BusLogic=QueueDepth:[,7,15];QueueDepth:31,BusSettleTime:30"
-
-INSMOD Loadable Kernel Module Installation Facility::
-
- insmod BusLogic.o \
- 'BusLogic="QueueDepth:[,7,15];QueueDepth:31,BusSettleTime:30"'
-
-
-.. Note::
-
- Module Utilities 2.1.71 or later is required for correct parsing
- of driver options containing commas.
-
-
-Driver Installation
-===================
-
-This distribution was prepared for Linux kernel version 2.0.35, but should be
-compatible with 2.0.4 or any later 2.0 series kernel.
-
-To install the new BusLogic SCSI driver, you may use the following commands,
-replacing "/usr/src" with wherever you keep your Linux kernel source tree::
-
- cd /usr/src
- tar -xvzf BusLogic-2.0.15.tar.gz
- mv README.* LICENSE.* BusLogic.[ch] FlashPoint.c linux/drivers/scsi
- patch -p0 < BusLogic.patch (only for 2.0.33 and below)
- cd linux
- make config
- make zImage
-
-Then install "arch/x86/boot/zImage" as your standard kernel, run lilo if
-appropriate, and reboot.
-

- ANNOUNCEMENT
- BusLogic FlashPoint LT/BT-948 Upgrade Program
- 1 February 1996
-
- ADDITIONAL ANNOUNCEMENT
- BusLogic FlashPoint LW/BT-958 Upgrade Program
- 14 June 1996
-
- Ever since its introduction last October, the BusLogic FlashPoint LT has
- been problematic for members of the Linux community, in that no Linux
- drivers have been available for this new Ultra SCSI product. Despite its
- officially being positioned as a desktop workstation product, and not being
- particularly well suited for a high performance multitasking operating
- system like Linux, the FlashPoint LT has been touted by computer system
- vendors as the latest thing, and has been sold even on many of their high
- end systems, to the exclusion of the older MultiMaster products. This has
- caused grief for many people who inadvertently purchased a system expecting
- that all BusLogic SCSI Host Adapters were supported by Linux, only to
- discover that the FlashPoint was not supported and would not be for quite
- some time, if ever.
-
- After this problem was identified, BusLogic contacted its major OEM
- customers to make sure the BT-946C/956C MultiMaster cards would still be
- made available, and that Linux users who mistakenly ordered systems with
- the FlashPoint would be able to upgrade to the BT-946C. While this helped
- many purchasers of new systems, it was only a partial solution to the
- overall problem of FlashPoint support for Linux users. It did nothing to
- assist the people who initially purchased a FlashPoint for a supported
- operating system and then later decided to run Linux, or those who had
- ended up with a FlashPoint LT, believing it was supported, and were unable
- to return it.
-
- In the middle of December, I asked to meet with BusLogic's senior
- management to discuss the issues related to Linux and free software support
- for the FlashPoint. Rumors of varying accuracy had been circulating
- publicly about BusLogic's attitude toward the Linux community, and I felt
- it was best that these issues be addressed directly. I sent an email
- message after 11pm one evening, and the meeting took place the next
- afternoon. Unfortunately, corporate wheels sometimes grind slowly,
- especially when a company is being acquired, and so it's taken until now
- before the details were completely determined and a public statement could
- be made.
-
- BusLogic is not prepared at this time to release the information necessary
- for third parties to write drivers for the FlashPoint. The only existing
- FlashPoint drivers have been written directly by BusLogic Engineering, and
- there is no FlashPoint documentation sufficiently detailed to allow outside
- developers to write a driver without substantial assistance. While there
- are people at BusLogic who would rather not release the details of the
- FlashPoint architecture at all, that debate has not yet been settled either
- way. In any event, even if documentation were available today it would
- take quite a while for a usable driver to be written, especially since I'm
- not convinced that the effort required would be worthwhile.
-
- However, BusLogic does remain committed to providing a high performance
- SCSI solution for the Linux community, and does not want to see anyone left
- unable to run Linux because they have a Flashpoint LT. Therefore, BusLogic
- has put in place a direct upgrade program to allow any Linux user worldwide
- to trade in their FlashPoint LT for the new BT-948 MultiMaster PCI Ultra
- SCSI Host Adapter. The BT-948 is the Ultra SCSI successor to the BT-946C
- and has all the best features of both the BT-946C and FlashPoint LT,
- including smart termination and a flash PROM for easy firmware updates, and
- is of course compatible with the present Linux driver. The price for this
- upgrade has been set at US $45 plus shipping and handling, and the upgrade
- program will be administered through BusLogic Technical Support, which can
- be reached by electronic mail at techsup-p+6rfT8T97tWk0Htik3J/w@public.gmane.org, by Voice at +1 408
- 654-0760, or by FAX at +1 408 492-1542.
-
- As of 14 June 1996, the original BusLogic FlashPoint LT to BT-948 upgrade
- program has now been extended to encompass the FlashPoint LW Wide Ultra
- SCSI Host Adapter. Any Linux user worldwide may trade in their FlashPoint
- LW (BT-950) for a BT-958 MultiMaster PCI Ultra SCSI Host Adapter. The
- price for this upgrade has been set at US $65 plus shipping and handling.
-
- I was a beta test site for the BT-948/958, and versions 1.2.1 and 1.3.1 of
- my BusLogic driver already included latent support for the BT-948/958.
- Additional cosmetic support for the Ultra SCSI MultiMaster cards was added
- subsequent releases. As a result of this cooperative testing process,
- several firmware bugs were found and corrected. My heavily loaded Linux
- test system provided an ideal environment for testing error recovery
- processes that are much more rarely exercised in production systems, but
- are crucial to overall system stability. It was especially convenient
- being able to work directly with their firmware engineer in demonstrating
- the problems under control of the firmware debugging environment; things
- sure have come a long way since the last time I worked on firmware for an
- embedded system. I am presently working on some performance testing and
- expect to have some data to report in the not too distant future.
-
- BusLogic asked me to send this announcement since a large percentage of the
- questions regarding support for the FlashPoint have either been sent to me
- directly via email, or have appeared in the Linux newsgroups in which I
- participate. To summarize, BusLogic is offering Linux users an upgrade
- from the unsupported FlashPoint LT (BT-930) to the supported BT-948 for US
- $45 plus shipping and handling, or from the unsupported FlashPoint LW
- (BT-950) to the supported BT-958 for $65 plus shipping and handling.
- Contact BusLogic Technical Support at techsup-p+6rfT8T97tWk0Htik3J/w@public.gmane.org or +1 408
- 654-0760 to take advantage of their offer.

From: Arnd Bergmann <arnd@arndb.de>
All architecture-independent users of virt_to_bus() and bus_to_virt()
have been fixed to use the dma mapping interfaces or have been
removed now. This means the definitions on most architectures, and the
CONFIG_VIRT_TO_BUS symbol are now obsolete and can be removed.
The only exceptions to this are a few network and scsi drivers for m68k
Amiga and VME machines and ppc32 Macintosh. These drivers work correctly
with the old interfaces and are probably not worth changing.
On alpha and parisc, virt_to_bus() were still used in asm/floppy.h.
alpha can use isa_virt_to_bus() like x86 does, and parisc can just
open-code the virt_to_phys() here, as this is architecture specific
code.
I tried updating the bus-virt-phys-mapping.rst documentation, which
started as an email from Linus to explain some details of the Linux-2.0
driver interfaces. The bits about virt_to_bus() were declared obsolete
backin 2000, and the rest is not all that relevant any more, so in the
end I just decided to remove the file completely.

-==========================================================
-How to access I/O mapped memory from within device drivers
-==========================================================
-
-:Author: Linus
-
-.. warning::
-
- The virt_to_bus() and bus_to_virt() functions have been
- superseded by the functionality provided by the PCI DMA interface
- (see Documentation/core-api/dma-api-howto.rst). They continue
- to be documented below for historical purposes, but new code
- must not use them. --davidm 00/12/12
-
-::
-
- [ This is a mail message in response to a query on IO mapping, thus the
- strange format for a "document" ]
-
-The AHA-1542 is a bus-master device, and your patch makes the driver give the
-controller the physical address of the buffers, which is correct on x86
-(because all bus master devices see the physical memory mappings directly).
-
-However, on many setups, there are actually **three** different ways of looking
-at memory addresses, and in this case we actually want the third, the
-so-called "bus address".
-
-Essentially, the three ways of addressing memory are (this is "real memory",
-that is, normal RAM--see later about other details):
-
- - CPU untranslated. This is the "physical" address. Physical address
- 0 is what the CPU sees when it drives zeroes on the memory bus.
-
- - CPU translated address. This is the "virtual" address, and is
- completely internal to the CPU itself with the CPU doing the appropriate
- translations into "CPU untranslated".
-
- - bus address. This is the address of memory as seen by OTHER devices,
- not the CPU. Now, in theory there could be many different bus
- addresses, with each device seeing memory in some device-specific way, but
- happily most hardware designers aren't actually actively trying to make
- things any more complex than necessary, so you can assume that all
- external hardware sees the memory the same way.
-
-Now, on normal PCs the bus address is exactly the same as the physical
-address, and things are very simple indeed. However, they are that simple
-because the memory and the devices share the same address space, and that is
-not generally necessarily true on other PCI/ISA setups.
-
-Now, just as an example, on the PReP (PowerPC Reference Platform), the
-CPU sees a memory map something like this (this is from memory)::
-
- 0-2 GB "real memory"
- 2 GB-3 GB "system IO" (inb/out and similar accesses on x86)
- 3 GB-4 GB "IO memory" (shared memory over the IO bus)
-
-Now, that looks simple enough. However, when you look at the same thing from
-the viewpoint of the devices, you have the reverse, and the physical memory
-address 0 actually shows up as address 2 GB for any IO master.
-
-So when the CPU wants any bus master to write to physical memory 0, it
-has to give the master address 0x80000000 as the memory address.
-
-So, for example, depending on how the kernel is actually mapped on the
-PPC, you can end up with a setup like this::
-
- physical address: 0
- virtual address: 0xC0000000
- bus address: 0x80000000
-
-where all the addresses actually point to the same thing. It's just seen
-through different translations..
-
-Similarly, on the Alpha, the normal translation is::
-
- physical address: 0
- virtual address: 0xfffffc0000000000
- bus address: 0x40000000
-
-(but there are also Alphas where the physical address and the bus address
-are the same).
-
-Anyway, the way to look up all these translations, you do::
-
- #include <asm/io.h>
-
- phys_addr = virt_to_phys(virt_addr);
- virt_addr = phys_to_virt(phys_addr);
- bus_addr = virt_to_bus(virt_addr);
- virt_addr = bus_to_virt(bus_addr);
-
-Now, when do you need these?
-
-You want the **virtual** address when you are actually going to access that
-pointer from the kernel. So you can have something like this::
-
- /*
- * this is the hardware "mailbox" we use to communicate with
- * the controller. The controller sees this directly.
- */
- struct mailbox {
- __u32 status;
- __u32 bufstart;
- __u32 buflen;
- ..
- } mbox;
-
- unsigned char * retbuffer;
-
- /* get the address from the controller */
- retbuffer = bus_to_virt(mbox.bufstart);
- switch (retbuffer[0]) {
- case STATUS_OK:
- ...
-
-on the other hand, you want the bus address when you have a buffer that
-you want to give to the controller::
-
- /* ask the controller to read the sense status into "sense_buffer" */
- mbox.bufstart = virt_to_bus(&sense_buffer);
- mbox.buflen = sizeof(sense_buffer);
- mbox.status = 0;
- notify_controller(&mbox);
-
-And you generally **never** want to use the physical address, because you can't
-use that from the CPU (the CPU only uses translated virtual addresses), and
-you can't use it from the bus master.
-
-So why do we care about the physical address at all? We do need the physical
-address in some cases, it's just not very often in normal code. The physical
-address is needed if you use memory mappings, for example, because the
-"remap_pfn_range()" mm function wants the physical address of the memory to
-be remapped as measured in units of pages, a.k.a. the pfn (the memory
-management layer doesn't know about devices outside the CPU, so it
-shouldn't need to know about "bus addresses" etc).
-
-.. note::
-
- The above is only one part of the whole equation. The above
- only talks about "real memory", that is, CPU memory (RAM).
-
-There is a completely different type of memory too, and that's the "shared
-memory" on the PCI or ISA bus. That's generally not RAM (although in the case
-of a video graphics card it can be normal DRAM that is just used for a frame
-buffer), but can be things like a packet buffer in a network card etc.
-
-This memory is called "PCI memory" or "shared memory" or "IO memory" or
-whatever, and there is only one way to access it: the readb/writeb and
-related functions. You should never take the address of such memory, because
-there is really nothing you can do with such an address: it's not
-conceptually in the same memory space as "real memory" at all, so you cannot
-just dereference a pointer. (Sadly, on x86 it **is** in the same memory space,
-so on x86 it actually works to just deference a pointer, but it's not
-portable).
-
-For such memory, you can do things like:
-
- - reading::
-
- /*
- * read first 32 bits from ISA memory at 0xC0000, aka
- * C000:0000 in DOS terms
- */
- unsigned int signature = isa_readl(0xC0000);
-
- - remapping and writing::
-
- /*
- * remap framebuffer PCI memory area at 0xFC000000,
- * size 1MB, so that we can access it: We can directly
- * access only the 640k-1MB area, so anything else
- * has to be remapped.
- */
- void __iomem *baseptr = ioremap(0xFC000000, 1024*1024);
-
- /* write a 'A' to the offset 10 of the area */
- writeb('A',baseptr+10);
-
- /* unmap when we unload the driver */
- iounmap(baseptr);
-
- - copying and clearing::
-
- /* get the 6-byte Ethernet address at ISA address E000:0040 */
- memcpy_fromio(kernel_buffer, 0xE0040, 6);
- /* write a packet to the driver */
- memcpy_toio(0xE1000, skb->data, skb->len);
- /* clear the frame buffer */
- memset_io(0xA0000, 0, 0x10000);
-
-OK, that just about covers the basics of accessing IO portably. Questions?
-Comments? You may think that all the above is overly complex, but one day you
-might find yourself with a 500 MHz Alpha in front of you, and then you'll be
-happy that your driver works ;)
-
-Note that kernel versions 2.0.x (and earlier) mistakenly called the
-ioremap() function "vremap()". ioremap() is the proper name, but I
-didn't think straight when I wrote it originally. People who have to
-support both can do something like::
-
- /* support old naming silliness */
- #if LINUX_VERSION_CODE < 0x020100
- #define ioremap vremap
- #define iounmap vfree
- #endif
-
-at the top of their source files, and then they can use the right names
-even on 2.0.x systems.
-
-And the above sounds worse than it really is. Most real drivers really
-don't do all that complex things (or rather: the complexity is not so
-much in the actual IO accesses as in error handling and timeouts etc).
-It's generally not hard to fix drivers, and in many cases the code
-actually looks better afterwards::
-
- unsigned long signature = *(unsigned int *) 0xC0000;
- vs
- unsigned long signature = readl(0xC0000);
-
-I think the second version actually is more readable, no?

* [PATCH 6/6] arch/*/: remove CONFIG_VIRT_TO_BUS

From: Arnd Bergmann <arnd@arndb.de>
All architecture-independent users of virt_to_bus() and bus_to_virt()
have been fixed to use the dma mapping interfaces or have been
removed now. This means the definitions on most architectures, and the
CONFIG_VIRT_TO_BUS symbol are now obsolete and can be removed.
The only exceptions to this are a few network and scsi drivers for m68k
Amiga and VME machines and ppc32 Macintosh. These drivers work correctly
with the old interfaces and are probably not worth changing.
On alpha and parisc, virt_to_bus() were still used in asm/floppy.h.
alpha can use isa_virt_to_bus() like x86 does, and parisc can just
open-code the virt_to_phys() here, as this is architecture specific
code.
I tried updating the bus-virt-phys-mapping.rst documentation, which
started as an email from Linus to explain some details of the Linux-2.0
driver interfaces. The bits about virt_to_bus() were declared obsolete
backin 2000, and the rest is not all that relevant any more, so in the
end I just decided to remove the file completely.

-==========================================================
-How to access I/O mapped memory from within device drivers
-==========================================================
-
-:Author: Linus
-
-.. warning::
-
- The virt_to_bus() and bus_to_virt() functions have been
- superseded by the functionality provided by the PCI DMA interface
- (see Documentation/core-api/dma-api-howto.rst). They continue
- to be documented below for historical purposes, but new code
- must not use them. --davidm 00/12/12
-
-::
-
- [ This is a mail message in response to a query on IO mapping, thus the
- strange format for a "document" ]
-
-The AHA-1542 is a bus-master device, and your patch makes the driver give the
-controller the physical address of the buffers, which is correct on x86
-(because all bus master devices see the physical memory mappings directly).
-
-However, on many setups, there are actually **three** different ways of looking
-at memory addresses, and in this case we actually want the third, the
-so-called "bus address".
-
-Essentially, the three ways of addressing memory are (this is "real memory",
-that is, normal RAM--see later about other details):
-
- - CPU untranslated. This is the "physical" address. Physical address
- 0 is what the CPU sees when it drives zeroes on the memory bus.
-
- - CPU translated address. This is the "virtual" address, and is
- completely internal to the CPU itself with the CPU doing the appropriate
- translations into "CPU untranslated".
-
- - bus address. This is the address of memory as seen by OTHER devices,
- not the CPU. Now, in theory there could be many different bus
- addresses, with each device seeing memory in some device-specific way, but
- happily most hardware designers aren't actually actively trying to make
- things any more complex than necessary, so you can assume that all
- external hardware sees the memory the same way.
-
-Now, on normal PCs the bus address is exactly the same as the physical
-address, and things are very simple indeed. However, they are that simple
-because the memory and the devices share the same address space, and that is
-not generally necessarily true on other PCI/ISA setups.
-
-Now, just as an example, on the PReP (PowerPC Reference Platform), the
-CPU sees a memory map something like this (this is from memory)::
-
- 0-2 GB "real memory"
- 2 GB-3 GB "system IO" (inb/out and similar accesses on x86)
- 3 GB-4 GB "IO memory" (shared memory over the IO bus)
-
-Now, that looks simple enough. However, when you look at the same thing from
-the viewpoint of the devices, you have the reverse, and the physical memory
-address 0 actually shows up as address 2 GB for any IO master.
-
-So when the CPU wants any bus master to write to physical memory 0, it
-has to give the master address 0x80000000 as the memory address.
-
-So, for example, depending on how the kernel is actually mapped on the
-PPC, you can end up with a setup like this::
-
- physical address: 0
- virtual address: 0xC0000000
- bus address: 0x80000000
-
-where all the addresses actually point to the same thing. It's just seen
-through different translations..
-
-Similarly, on the Alpha, the normal translation is::
-
- physical address: 0
- virtual address: 0xfffffc0000000000
- bus address: 0x40000000
-
-(but there are also Alphas where the physical address and the bus address
-are the same).
-
-Anyway, the way to look up all these translations, you do::
-
- #include <asm/io.h>
-
- phys_addr = virt_to_phys(virt_addr);
- virt_addr = phys_to_virt(phys_addr);
- bus_addr = virt_to_bus(virt_addr);
- virt_addr = bus_to_virt(bus_addr);
-
-Now, when do you need these?
-
-You want the **virtual** address when you are actually going to access that
-pointer from the kernel. So you can have something like this::
-
- /*
- * this is the hardware "mailbox" we use to communicate with
- * the controller. The controller sees this directly.
- */
- struct mailbox {
- __u32 status;
- __u32 bufstart;
- __u32 buflen;
- ..
- } mbox;
-
- unsigned char * retbuffer;
-
- /* get the address from the controller */
- retbuffer = bus_to_virt(mbox.bufstart);
- switch (retbuffer[0]) {
- case STATUS_OK:
- ...
-
-on the other hand, you want the bus address when you have a buffer that
-you want to give to the controller::
-
- /* ask the controller to read the sense status into "sense_buffer" */
- mbox.bufstart = virt_to_bus(&sense_buffer);
- mbox.buflen = sizeof(sense_buffer);
- mbox.status = 0;
- notify_controller(&mbox);
-
-And you generally **never** want to use the physical address, because you can't
-use that from the CPU (the CPU only uses translated virtual addresses), and
-you can't use it from the bus master.
-
-So why do we care about the physical address at all? We do need the physical
-address in some cases, it's just not very often in normal code. The physical
-address is needed if you use memory mappings, for example, because the
-"remap_pfn_range()" mm function wants the physical address of the memory to
-be remapped as measured in units of pages, a.k.a. the pfn (the memory
-management layer doesn't know about devices outside the CPU, so it
-shouldn't need to know about "bus addresses" etc).
-
-.. note::
-
- The above is only one part of the whole equation. The above
- only talks about "real memory", that is, CPU memory (RAM).
-
-There is a completely different type of memory too, and that's the "shared
-memory" on the PCI or ISA bus. That's generally not RAM (although in the case
-of a video graphics card it can be normal DRAM that is just used for a frame
-buffer), but can be things like a packet buffer in a network card etc.
-
-This memory is called "PCI memory" or "shared memory" or "IO memory" or
-whatever, and there is only one way to access it: the readb/writeb and
-related functions. You should never take the address of such memory, because
-there is really nothing you can do with such an address: it's not
-conceptually in the same memory space as "real memory" at all, so you cannot
-just dereference a pointer. (Sadly, on x86 it **is** in the same memory space,
-so on x86 it actually works to just deference a pointer, but it's not
-portable).
-
-For such memory, you can do things like:
-
- - reading::
-
- /*
- * read first 32 bits from ISA memory at 0xC0000, aka
- * C000:0000 in DOS terms
- */
- unsigned int signature = isa_readl(0xC0000);
-
- - remapping and writing::
-
- /*
- * remap framebuffer PCI memory area at 0xFC000000,
- * size 1MB, so that we can access it: We can directly
- * access only the 640k-1MB area, so anything else
- * has to be remapped.
- */
- void __iomem *baseptr = ioremap(0xFC000000, 1024*1024);
-

- memcpy_fromio(kernel_buffer, 0xE0040, 6);
- /* write a packet to the driver */
- memcpy_toio(0xE1000, skb->data, skb->len);
- /* clear the frame buffer */
- memset_io(0xA0000, 0, 0x10000);
-
-OK, that just about covers the basics of accessing IO portably. Questions?
-Comments? You may think that all the above is overly complex, but one day you
-might find yourself with a 500 MHz Alpha in front of you, and then you'll be
-happy that your driver works ;)
-
-Note that kernel versions 2.0.x (and earlier) mistakenly called the
-ioremap() function "vremap()". ioremap() is the proper name, but I
-didn't think straight when I wrote it originally. People who have to
-support both can do something like::
-
- /* support old naming silliness */
- #if LINUX_VERSION_CODE < 0x020100
- #define ioremap vremap
- #define iounmap vfree
- #endif
-
-at the top of their source files, and then they can use the right names
-even on 2.0.x systems.
-
-And the above sounds worse than it really is. Most real drivers really
-don't do all that complex things (or rather: the complexity is not so
-much in the actual IO accesses as in error handling and timeouts etc).
-It's generally not hard to fix drivers, and in many cases the code
-actually looks better afterwards::
-
- unsigned long signature = *(unsigned int *) 0xC0000;
- vs
- unsigned long signature = readl(0xC0000);
-
-I think the second version actually is more readable, no?

From: Arnd Bergmann <arnd@arndb.de>
All architecture-independent users of virt_to_bus() and bus_to_virt()
have been fixed to use the dma mapping interfaces or have been
removed now. This means the definitions on most architectures, and the
CONFIG_VIRT_TO_BUS symbol are now obsolete and can be removed.
The only exceptions to this are a few network and scsi drivers for m68k
Amiga and VME machines and ppc32 Macintosh. These drivers work correctly
with the old interfaces and are probably not worth changing.
On alpha and parisc, virt_to_bus() were still used in asm/floppy.h.
alpha can use isa_virt_to_bus() like x86 does, and parisc can just
open-code the virt_to_phys() here, as this is architecture specific
code.
I tried updating the bus-virt-phys-mapping.rst documentation, which
started as an email from Linus to explain some details of the Linux-2.0
driver interfaces. The bits about virt_to_bus() were declared obsolete
backin 2000, and the rest is not all that relevant any more, so in the
end I just decided to remove the file completely.

-How to access I/O mapped memory from within device drivers

-:Author: Linus
-
-.. warning::
-
- The virt_to_bus() and bus_to_virt() functions have been
- superseded by the functionality provided by the PCI DMA interface
- (see Documentation/core-api/dma-api-howto.rst). They continue
- to be documented below for historical purposes, but new code
- must not use them. --davidm 00/12/12
-
-::
-
- [ This is a mail message in response to a query on IO mapping, thus the
- strange format for a "document" ]
-
-The AHA-1542 is a bus-master device, and your patch makes the driver give the
-controller the physical address of the buffers, which is correct on x86
-(because all bus master devices see the physical memory mappings directly).
-
-However, on many setups, there are actually **three** different ways of looking
-at memory addresses, and in this case we actually want the third, the
-so-called "bus address".
-
-Essentially, the three ways of addressing memory are (this is "real memory",
-that is, normal RAM--see later about other details):
-
- - CPU untranslated. This is the "physical" address. Physical address
- 0 is what the CPU sees when it drives zeroes on the memory bus.
-
- - CPU translated address. This is the "virtual" address, and is
- completely internal to the CPU itself with the CPU doing the appropriate
- translations into "CPU untranslated".
-
- - bus address. This is the address of memory as seen by OTHER devices,
- not the CPU. Now, in theory there could be many different bus
- addresses, with each device seeing memory in some device-specific way, but
- happily most hardware designers aren't actually actively trying to make
- things any more complex than necessary, so you can assume that all
- external hardware sees the memory the same way.
-
-Now, on normal PCs the bus address is exactly the same as the physical
-address, and things are very simple indeed. However, they are that simple
-because the memory and the devices share the same address space, and that is
-not generally necessarily true on other PCI/ISA setups.
-
-Now, just as an example, on the PReP (PowerPC Reference Platform), the
-CPU sees a memory map something like this (this is from memory)::
-
- 0-2 GB "real memory"
- 2 GB-3 GB "system IO" (inb/out and similar accesses on x86)
- 3 GB-4 GB "IO memory" (shared memory over the IO bus)
-
-Now, that looks simple enough. However, when you look at the same thing from
-the viewpoint of the devices, you have the reverse, and the physical memory
-address 0 actually shows up as address 2 GB for any IO master.
-
-So when the CPU wants any bus master to write to physical memory 0, it
-has to give the master address 0x80000000 as the memory address.
-
-So, for example, depending on how the kernel is actually mapped on the
-PPC, you can end up with a setup like this::
-
- physical address: 0
- virtual address: 0xC0000000
- bus address: 0x80000000
-
-where all the addresses actually point to the same thing. It's just seen
-through different translations..
-
-Similarly, on the Alpha, the normal translation is::
-
- physical address: 0
- virtual address: 0xfffffc0000000000
- bus address: 0x40000000
-
-(but there are also Alphas where the physical address and the bus address
-are the same).
-
-Anyway, the way to look up all these translations, you do::
-
- #include <asm/io.h>
-
- phys_addr = virt_to_phys(virt_addr);
- virt_addr = phys_to_virt(phys_addr);
- bus_addr = virt_to_bus(virt_addr);
- virt_addr = bus_to_virt(bus_addr);
-
-Now, when do you need these?
-
-You want the **virtual** address when you are actually going to access that
-pointer from the kernel. So you can have something like this::
-
- /*
- * this is the hardware "mailbox" we use to communicate with
- * the controller. The controller sees this directly.
- */
- struct mailbox {
- __u32 status;
- __u32 bufstart;
- __u32 buflen;
- ..
- } mbox;
-
- unsigned char * retbuffer;
-
- /* get the address from the controller */
- retbuffer = bus_to_virt(mbox.bufstart);
- switch (retbuffer[0]) {
- case STATUS_OK:
- ...
-
-on the other hand, you want the bus address when you have a buffer that
-you want to give to the controller::
-
- /* ask the controller to read the sense status into "sense_buffer" */
- mbox.bufstart = virt_to_bus(&sense_buffer);
- mbox.buflen = sizeof(sense_buffer);
- mbox.status = 0;
- notify_controller(&mbox);
-
-And you generally **never** want to use the physical address, because you can't
-use that from the CPU (the CPU only uses translated virtual addresses), and
-you can't use it from the bus master.
-
-So why do we care about the physical address at all? We do need the physical
-address in some cases, it's just not very often in normal code. The physical
-address is needed if you use memory mappings, for example, because the
-"remap_pfn_range()" mm function wants the physical address of the memory to
-be remapped as measured in units of pages, a.k.a. the pfn (the memory
-management layer doesn't know about devices outside the CPU, so it
-shouldn't need to know about "bus addresses" etc).
-
-.. note::
-
- The above is only one part of the whole equation. The above
- only talks about "real memory", that is, CPU memory (RAM).
-
-There is a completely different type of memory too, and that's the "shared
-memory" on the PCI or ISA bus. That's generally not RAM (although in the case
-of a video graphics card it can be normal DRAM that is just used for a frame
-buffer), but can be things like a packet buffer in a network card etc.
-
-This memory is called "PCI memory" or "shared memory" or "IO memory" or
-whatever, and there is only one way to access it: the readb/writeb and
-related functions. You should never take the address of such memory, because
-there is really nothing you can do with such an address: it's not
-conceptually in the same memory space as "real memory" at all, so you cannot
-just dereference a pointer. (Sadly, on x86 it **is** in the same memory space,
-so on x86 it actually works to just deference a pointer, but it's not
-portable).
-
-For such memory, you can do things like:
-
- - reading::
-
- /*
- * read first 32 bits from ISA memory at 0xC0000, aka
- * C000:0000 in DOS terms
- */
- unsigned int signature = isa_readl(0xC0000);
-
- - remapping and writing::
-
- /*
- * remap framebuffer PCI memory area at 0xFC000000,
- * size 1MB, so that we can access it: We can directly
- * access only the 640k-1MB area, so anything else
- * has to be remapped.
- */
- void __iomem *baseptr = ioremap(0xFC000000, 1024*1024);
-
- /* write a 'A' to the offset 10 of the area */
- writeb('A',baseptr+10);
-
- /* unmap when we unload the driver */
- iounmap(baseptr);
-
- - copying and clearing::
-
- /* get the 6-byte Ethernet address at ISA address E000:0040 */
- memcpy_fromio(kernel_buffer, 0xE0040, 6);
- /* write a packet to the driver */
- memcpy_toio(0xE1000, skb->data, skb->len);
- /* clear the frame buffer */
- memset_io(0xA0000, 0, 0x10000);
-
-OK, that just about covers the basics of accessing IO portably. Questions?
-Comments? You may think that all the above is overly complex, but one day you
-might find yourself with a 500 MHz Alpha in front of you, and then you'll be
-happy that your driver works ;)
-
-Note that kernel versions 2.0.x (and earlier) mistakenly called the
-ioremap() function "vremap()". ioremap() is the proper name, but I
-didn't think straight when I wrote it originally. People who have to
-support both can do something like::
-
- /* support old naming silliness */
- #if LINUX_VERSION_CODE < 0x020100
- #define ioremap vremap
- #define iounmap vfree
- #endif
-
-at the top of their source files, and then they can use the right names
-even on 2.0.x systems.
-
-And the above sounds worse than it really is. Most real drivers really
-don't do all that complex things (or rather: the complexity is not so
-much in the actual IO accesses as in error handling and timeouts etc).
-It's generally not hard to fix drivers, and in many cases the code
-actually looks better afterwards::
-
- unsigned long signature = *(unsigned int *) 0xC0000;
- vs
- unsigned long signature = readl(0xC0000);
-
-I think the second version actually is more readable, no?

From: Arnd Bergmann <arnd-r2nGTMty4D4@public.gmane.org>
All architecture-independent users of virt_to_bus() and bus_to_virt()
have been fixed to use the dma mapping interfaces or have been
removed now. This means the definitions on most architectures, and the
CONFIG_VIRT_TO_BUS symbol are now obsolete and can be removed.
The only exceptions to this are a few network and scsi drivers for m68k
Amiga and VME machines and ppc32 Macintosh. These drivers work correctly
with the old interfaces and are probably not worth changing.
On alpha and parisc, virt_to_bus() were still used in asm/floppy.h.
alpha can use isa_virt_to_bus() like x86 does, and parisc can just
open-code the virt_to_phys() here, as this is architecture specific
code.
I tried updating the bus-virt-phys-mapping.rst documentation, which
started as an email from Linus to explain some details of the Linux-2.0
driver interfaces. The bits about virt_to_bus() were declared obsolete
backin 2000, and the rest is not all that relevant any more, so in the
end I just decided to remove the file completely.

-==========================================================
-How to access I/O mapped memory from within device drivers
-==========================================================
-
-:Author: Linus
-
-.. warning::
-
- The virt_to_bus() and bus_to_virt() functions have been
- superseded by the functionality provided by the PCI DMA interface
- (see Documentation/core-api/dma-api-howto.rst). They continue
- to be documented below for historical purposes, but new code
- must not use them. --davidm 00/12/12
-
-::
-
- [ This is a mail message in response to a query on IO mapping, thus the
- strange format for a "document" ]
-
-The AHA-1542 is a bus-master device, and your patch makes the driver give the
-controller the physical address of the buffers, which is correct on x86
-(because all bus master devices see the physical memory mappings directly).
-
-However, on many setups, there are actually **three** different ways of looking
-at memory addresses, and in this case we actually want the third, the
-so-called "bus address".
-
-Essentially, the three ways of addressing memory are (this is "real memory",
-that is, normal RAM--see later about other details):
-
- - CPU untranslated. This is the "physical" address. Physical address
- 0 is what the CPU sees when it drives zeroes on the memory bus.
-
- - CPU translated address. This is the "virtual" address, and is
- completely internal to the CPU itself with the CPU doing the appropriate
- translations into "CPU untranslated".
-
- - bus address. This is the address of memory as seen by OTHER devices,
- not the CPU. Now, in theory there could be many different bus
- addresses, with each device seeing memory in some device-specific way, but
- happily most hardware designers aren't actually actively trying to make
- things any more complex than necessary, so you can assume that all
- external hardware sees the memory the same way.
-
-Now, on normal PCs the bus address is exactly the same as the physical
-address, and things are very simple indeed. However, they are that simple
-because the memory and the devices share the same address space, and that is
-not generally necessarily true on other PCI/ISA setups.
-
-Now, just as an example, on the PReP (PowerPC Reference Platform), the
-CPU sees a memory map something like this (this is from memory)::
-
- 0-2 GB "real memory"
- 2 GB-3 GB "system IO" (inb/out and similar accesses on x86)
- 3 GB-4 GB "IO memory" (shared memory over the IO bus)
-
-Now, that looks simple enough. However, when you look at the same thing from
-the viewpoint of the devices, you have the reverse, and the physical memory
-address 0 actually shows up as address 2 GB for any IO master.
-
-So when the CPU wants any bus master to write to physical memory 0, it
-has to give the master address 0x80000000 as the memory address.
-
-So, for example, depending on how the kernel is actually mapped on the
-PPC, you can end up with a setup like this::
-
- physical address: 0
- virtual address: 0xC0000000
- bus address: 0x80000000
-
-where all the addresses actually point to the same thing. It's just seen
-through different translations..
-
-Similarly, on the Alpha, the normal translation is::
-
- physical address: 0
- virtual address: 0xfffffc0000000000
- bus address: 0x40000000
-
-(but there are also Alphas where the physical address and the bus address
-are the same).
-
-Anyway, the way to look up all these translations, you do::
-
- #include <asm/io.h>
-
- phys_addr = virt_to_phys(virt_addr);
- virt_addr = phys_to_virt(phys_addr);
- bus_addr = virt_to_bus(virt_addr);
- virt_addr = bus_to_virt(bus_addr);
-
-Now, when do you need these?
-
-You want the **virtual** address when you are actually going to access that
-pointer from the kernel. So you can have something like this::
-
- /*
- * this is the hardware "mailbox" we use to communicate with
- * the controller. The controller sees this directly.
- */
- struct mailbox {
- __u32 status;
- __u32 bufstart;
- __u32 buflen;
- ..
- } mbox;
-
- unsigned char * retbuffer;
-
- /* get the address from the controller */
- retbuffer = bus_to_virt(mbox.bufstart);
- switch (retbuffer[0]) {
- case STATUS_OK:
- ...
-
-on the other hand, you want the bus address when you have a buffer that
-you want to give to the controller::
-
- /* ask the controller to read the sense status into "sense_buffer" */
- mbox.bufstart = virt_to_bus(&sense_buffer);
- mbox.buflen = sizeof(sense_buffer);
- mbox.status = 0;
- notify_controller(&mbox);
-
-And you generally **never** want to use the physical address, because you can't
-use that from the CPU (the CPU only uses translated virtual addresses), and
-you can't use it from the bus master.
-
-So why do we care about the physical address at all? We do need the physical
-address in some cases, it's just not very often in normal code. The physical
-address is needed if you use memory mappings, for example, because the
-"remap_pfn_range()" mm function wants the physical address of the memory to
-be remapped as measured in units of pages, a.k.a. the pfn (the memory
-management layer doesn't know about devices outside the CPU, so it
-shouldn't need to know about "bus addresses" etc).
-
-.. note::
-
- The above is only one part of the whole equation. The above
- only talks about "real memory", that is, CPU memory (RAM).
-
-There is a completely different type of memory too, and that's the "shared
-memory" on the PCI or ISA bus. That's generally not RAM (although in the case
-of a video graphics card it can be normal DRAM that is just used for a frame
-buffer), but can be things like a packet buffer in a network card etc.
-
-This memory is called "PCI memory" or "shared memory" or "IO memory" or
-whatever, and there is only one way to access it: the readb/writeb and
-related functions. You should never take the address of such memory, because
-there is really nothing you can do with such an address: it's not
-conceptually in the same memory space as "real memory" at all, so you cannot
-just dereference a pointer. (Sadly, on x86 it **is** in the same memory space,
-so on x86 it actually works to just deference a pointer, but it's not
-portable).
-
-For such memory, you can do things like:
-
- - reading::
-
- /*
- * read first 32 bits from ISA memory at 0xC0000, aka
- * C000:0000 in DOS terms
- */
- unsigned int signature = isa_readl(0xC0000);
-
- - remapping and writing::
-
- /*
- * remap framebuffer PCI memory area at 0xFC000000,
- * size 1MB, so that we can access it: We can directly
- * access only the 640k-1MB area, so anything else
- * has to be remapped.
- */
- void __iomem *baseptr = ioremap(0xFC000000, 1024*1024);
-
- /* write a 'A' to the offset 10 of the area */
- writeb('A',baseptr+10);
-
- /* unmap when we unload the driver */
- iounmap(baseptr);
-
- - copying and clearing::
-
- /* get the 6-byte Ethernet address at ISA address E000:0040 */
- memcpy_fromio(kernel_buffer, 0xE0040, 6);
- /* write a packet to the driver */
- memcpy_toio(0xE1000, skb->data, skb->len);
- /* clear the frame buffer */
- memset_io(0xA0000, 0, 0x10000);
-
-OK, that just about covers the basics of accessing IO portably. Questions?
-Comments? You may think that all the above is overly complex, but one day you
-might find yourself with a 500 MHz Alpha in front of you, and then you'll be
-happy that your driver works ;)
-
-Note that kernel versions 2.0.x (and earlier) mistakenly called the
-ioremap() function "vremap()". ioremap() is the proper name, but I
-didn't think straight when I wrote it originally. People who have to
-support both can do something like::
-
- /* support old naming silliness */
- #if LINUX_VERSION_CODE < 0x020100
- #define ioremap vremap
- #define iounmap vfree
- #endif
-
-at the top of their source files, and then they can use the right names
-even on 2.0.x systems.
-
-And the above sounds worse than it really is. Most real drivers really
-don't do all that complex things (or rather: the complexity is not so
-much in the actual IO accesses as in error handling and timeouts etc).
-It's generally not hard to fix drivers, and in many cases the code
-actually looks better afterwards::
-
- unsigned long signature = *(unsigned int *) 0xC0000;
- vs
- unsigned long signature = readl(0xC0000);
-
-I think the second version actually is more readable, no?

Umm, I use it with a 32-bit system, so it would be quite an issue for me
to discover a problem with 64-bit configurations. And I quite rely on
this system for various stuff too!

Thanks for the pointer and for cc-ing me. Please refrain from removing
the driver at least for this release cycle and let me fix it. It should
be easy to mimic what I did for the defza driver: all bus addresses in the
DMA API come associated with virtual addresses, so it is just a matter of
recording those somewhere for later use rather than trying to mess up with
bus addresses to figure out a reverse mapping.

Sure, no problem. It looks like I forgot to actually Cc you on the series
as I had meant to, glad it reached you anyway.

I looked at the defza driver and that one appears simpler to me, as you
can look up the virtual address from an index, but it's possible I missed
what you do here. I meant specifically the calculation added by commit
67af2b060e02 ("[SCSI] dpt_i2o: move from virt_to_bus/bus_to_virt
to dma_alloc_coherent") in the dpt_i2o driver that can be used to
compute the virtual address. If something simpler works as well, that
is of course better.

Sure, no problem. It looks like I forgot to actually Cc you on the series
as I had meant to, glad it reached you anyway.

I looked at the defza driver and that one appears simpler to me, as you
can look up the virtual address from an index, but it's possible I missed
what you do here. I meant specifically the calculation added by commit
67af2b060e02 ("[SCSI] dpt_i2o: move from virt_to_bus/bus_to_virt
to dma_alloc_coherent") in the dpt_i2o driver that can be used to
compute the virtual address. If something simpler works as well, that
is of course better.

Yes, that's perfect, as there are no actual interdependencies with the
other drivers -- applying the last patch first would just hide the driver
I'm removing here.

I would say no to removing BusLogic driver. Virtualbox is another
consumer of this driver. This driver is very old but I would rather fix
the issues than remove it until we do not have any users.

Hi,
I'd love to say that I could fix this stuff up, however I've lacked access to
suitable hardware for a long time now and don't foresee that changing any
time soon...

Seems that's not used by any drivers, so fine to remove.

Maciej already offered to help fix the driver, so I think it will be ok.
On the other hand, it sounds like VirtualBox users should not actually try to
use the BusLogic driver with modern Linux guests. From what I can tell
from the documentation [1], VirtualBox only provides this emulation because it
was shipped with early versions of VMware and is supported by Windows 2000
and earlier, but not actually on any modern Windows guest. The VMware
documentation in turn explicitly says that BusLogic does not work with 64-bit
guests [2], presumably this applies to both Windows and Linux guests.
