Ventura Series controller are Tri-mode. The controller and
firmware are capable of supporting NVMe devices and
PCIe switches to be connected with the controller. This
patch set adds driver level support for NVMe devices and
PCIe switches.
mpt3sas v4 patset:
1) Removed code which detects gaps/holes in IO data buffers.
2) Added Patch 14, This has sparse warning fixes.
mpt3sas v3 patset:
Posting version v3. This accommodates below changes
over v2 patch.
1. In the MPI header files patch, Reformatted headers to have type
and variable on one line as suggested.
2. As suggested, started using blk_queue_virt_boundary() API
for NVMe drives and simplified the PRP formation.
3. Removed 'TODO' comments.
Suganath Prabu S (14):
mpt3sas: Update MPI Header
mpt3sas: Add nvme device support in slave alloc, target alloc and
probe
mpt3sas: SGL to PRP Translation for I/Os to NVMe devices
mpt3sas: Added support for nvme encapsulated request message.
mpt3sas: API 's to support NVMe drive addition to SML
mpt3sas: API's to remove nvme drive from sml
mpt3sas: Handle NVMe PCIe device related events generated
from firmware.
mpt3sas: Set NVMe device queue depth as 128
mpt3sas: scan and add nvme device after controller reset
mpt3as: Add-Task-management-debug-info-for-NVMe-drives.
mpt3sas: NVMe drive support for BTDHMAPPING ioctl command and log info
mpt3sas: Fix nvme drives checking for tlr.
mpt3sas: Update mpt3sas driver version.
mpt3sas: Fix sparse warning

From: root <root@dhcp-135-24-192-103.dhcp.avagotech.net>
1) Added support for probing pcie device and adding NVMe drives to
SML and driver's internal list pcie_device_list.
2) Added support for determing NVMe as boot device.
3) Added nvme device support for call back functions scan_finished
target_alloc,slave_alloc,target destroy and slave destroy.
a) During scan, pcie devices are probed and added to SML to drivers
internal list.
b) target_alloc & slave alloc API's allocates resources for
(MPT3SAS_TARGET & MPT3SAS_DEVICE) private datas and holds
information like handle, target_id etc.
c) slave_destroy & target_destroy are called when driver unregisters
or removes device. Also frees allocated resources and info.

^ permalink raw reply related [flat|nested] 50+ messages in thread* [PATCH v4 02/14] mpt3sas: Add nvme device support in slave alloc, target alloc and probe
@ 2017-08-21 13:32 ` Suganath Prabu S
0 siblings, 0 replies; 50+ messages in thread
From: Suganath Prabu S @ 2017-08-21 13:32 UTC (permalink / raw)
From: root <root@dhcp-135-24-192-103.dhcp.avagotech.net>
1) Added support for probing pcie device and adding NVMe drives to
SML and driver's internal list pcie_device_list.
2) Added support for determing NVMe as boot device.
3) Added nvme device support for call back functions scan_finished
target_alloc,slave_alloc,target destroy and slave destroy.
a) During scan, pcie devices are probed and added to SML to drivers
internal list.
b) target_alloc & slave alloc API's allocates resources for
(MPT3SAS_TARGET & MPT3SAS_DEVICE) private datas and holds
information like handle, target_id etc.
c) slave_destroy & target_destroy are called when driver unregisters
or removes device. Also frees allocated resources and info.

* Added support for translating the SGLs associated with incoming
commands either to IEE SGL or NVMe PRPs for NVMe devices.
* The hardware translation of IEEE SGL to NVMe PRPs has limitation
and if a command cannot be translated by hardware then it will go
to firmware and the firmware needs to translate it. And this will
have a performance reduction. To avoid that driver proactively
checks whether the translation will be done in hardware or not,
if not then driver try to translate inside the driver.

+ * _base_build_nvme_prp - This function is called for NVMe end devices to build
+ * a native SGL (NVMe PRP). The native SGL is built starting in the first PRP
+ * entry of the NVMe message (PRP1). If the data buffer is small enough to be
+ * described entirely using PRP1, then PRP2 is not used. If needed, PRP2 is
+ * used to describe a larger data buffer. If the data buffer is too large to
+ * describe using the two PRP entriess inside the NVMe message, then PRP1
+ * describes the first data memory segment, and PRP2 contains a pointer to a PRP
+ * list located elsewhere in memory to describe the remaining data memory
+ * segments. The PRP list will be contiguous.
+
+ * The native SGL for NVMe devices is a Physical Region Page (PRP). A PRP
+ * consists of a list of PRP entries to describe a number of noncontigous
+ * physical memory segments as a single memory buffer, just as a SGL does. Note
+ * however, that this function is only used by the IOCTL call, so the memory
+ * given will be guaranteed to be contiguous. There is no need to translate
+ * non-contiguous SGL into a PRP in this case. All PRPs will describe
+ * contiguous space that is one page size each.
+ *
+ * Each NVMe message contains two PRP entries. The first (PRP1) either contains
+ * a PRP list pointer or a PRP element, depending upon the command. PRP2
+ * contains the second PRP element if the memory being described fits within 2
+ * PRP entries, or a PRP list pointer if the PRP spans more than two entries.
+ *
+ * A PRP list pointer contains the address of a PRP list, structured as a linear
+ * array of PRP entries. Each PRP entry in this list describes a segment of
+ * physical memory.
+ *
+ * Each 64-bit PRP entry comprises an address and an offset field. The address
+ * always points at the beginning of a 4KB physical memory page, and the offset
+ * describes where within that 4KB page the memory segment begins. Only the
+ * first element in a PRP list may contain a non-zero offest, implying that all
+ * memory segments following the first begin at the start of a 4KB page.
+ *
+ * Each PRP element normally describes 4KB of physical memory, with exceptions
+ * for the first and last elements in the list. If the memory being described
+ * by the list begins at a non-zero offset within the first 4KB page, then the
+ * first PRP element will contain a non-zero offset indicating where the region
+ * begins within the 4KB page. The last memory segment may end before the end
+ * of the 4KB segment, depending upon the overall size of the memory being
+ * described by the PRP list.
+ *
+ * Since PRP entries lack any indication of size, the overall data buffer length
+ * is used to determine where the end of the data memory buffer is located, and
+ * how many PRP entries are required to describe it.

From: Suganath Prabu S @ 2017-08-21 13:32 UTC (permalink / raw)
From: root <root@dhcp-135-24-192-103.dhcp.avagotech.net>
* Added support for translating the SGLs associated with incoming
commands either to IEE SGL or NVMe PRPs for NVMe devices.
* The hardware translation of IEEE SGL to NVMe PRPs has limitation
and if a command cannot be translated by hardware then it will go
to firmware and the firmware needs to translate it. And this will
have a performance reduction. To avoid that driver proactively
checks whether the translation will be done in hardware or not,
if not then driver try to translate inside the driver.

/**
+ * _base_build_nvme_prp - This function is called for NVMe end devices to build
+ * a native SGL (NVMe PRP). The native SGL is built starting in the first PRP
+ * entry of the NVMe message (PRP1). If the data buffer is small enough to be
+ * described entirely using PRP1, then PRP2 is not used. If needed, PRP2 is
+ * used to describe a larger data buffer. If the data buffer is too large to
+ * describe using the two PRP entriess inside the NVMe message, then PRP1
+ * describes the first data memory segment, and PRP2 contains a pointer to a PRP
+ * list located elsewhere in memory to describe the remaining data memory
+ * segments. The PRP list will be contiguous.
+
+ * The native SGL for NVMe devices is a Physical Region Page (PRP). A PRP
+ * consists of a list of PRP entries to describe a number of noncontigous
+ * physical memory segments as a single memory buffer, just as a SGL does. Note
+ * however, that this function is only used by the IOCTL call, so the memory
+ * given will be guaranteed to be contiguous. There is no need to translate
+ * non-contiguous SGL into a PRP in this case. All PRPs will describe
+ * contiguous space that is one page size each.
+ *
+ * Each NVMe message contains two PRP entries. The first (PRP1) either contains
+ * a PRP list pointer or a PRP element, depending upon the command. PRP2
+ * contains the second PRP element if the memory being described fits within 2
+ * PRP entries, or a PRP list pointer if the PRP spans more than two entries.
+ *
+ * A PRP list pointer contains the address of a PRP list, structured as a linear
+ * array of PRP entries. Each PRP entry in this list describes a segment of
+ * physical memory.
+ *
+ * Each 64-bit PRP entry comprises an address and an offset field. The address
+ * always points at the beginning of a 4KB physical memory page, and the offset
+ * describes where within that 4KB page the memory segment begins. Only the
+ * first element in a PRP list may contain a non-zero offest, implying that all
+ * memory segments following the first begin at the start of a 4KB page.
+ *
+ * Each PRP element normally describes 4KB of physical memory, with exceptions
+ * for the first and last elements in the list. If the memory being described
+ * by the list begins at a non-zero offset within the first 4KB page, then the
+ * first PRP element will contain a non-zero offset indicating where the region
+ * begins within the 4KB page. The last memory segment may end before the end
+ * of the 4KB segment, depending upon the overall size of the memory being
+ * described by the PRP list.
+ *
+ * Since PRP entries lack any indication of size, the overall data buffer length
+ * is used to determine where the end of the data memory buffer is located, and
+ * how many PRP entries are required to describe it.

From: root <root@dhcp-135-24-192-103.dhcp.avagotech.net>
* Mpt3sas driver uses the NVMe Encapsulated Request message to
send an NVMe command to an NVMe device attached to the IOC.
* Normal I/O commands like reads and writes are passed to the
controller as SCSI commands and the controller has the ability
to translate the commands to NVMe equivalent.
* This encapsulated NVMe command is used by applications to send
direct NVMe commands to NVMe drives or for handling unmap where
the translation at controller/firmware level is having
performance issues.

From: root <root@dhcp-135-24-192-103.dhcp.avagotech.net>
* Mpt3sas driver uses the NVMe Encapsulated Request message to
send an NVMe command to an NVMe device attached to the IOC.
* Normal I/O commands like reads and writes are passed to the
controller as SCSI commands and the controller has the ability
to translate the commands to NVMe equivalent.
* This encapsulated NVMe command is used by applications to send
direct NVMe commands to NVMe drives or for handling unmap where
the translation at controller/firmware level is having
performance issues.

From: root <root@dhcp-135-24-192-103.dhcp.avagotech.net>
* The controller firmware sends separate events for NVMe devices and
PCIe switches similar to existing SAS events.
* NVMe device detection, addition and removal are reported by the
firmware through PCIe Topology Change list events.
* The PCIe device state change events are sent when the firmware
detects any abnormal conditions with a NVMe device or switch.
* The enumeration event are sent when the firmware starts PCIe device
enumeration and stops.
* This patch has the code change to handle the events and add/remove
NVMe devices in driver's inventory.

^ permalink raw reply related [flat|nested] 50+ messages in thread* [PATCH v4 07/14] mpt3sas: Handle NVMe PCIe device related events generated from firmware.
@ 2017-08-21 13:32 ` Suganath Prabu S
0 siblings, 0 replies; 50+ messages in thread
From: Suganath Prabu S @ 2017-08-21 13:32 UTC (permalink / raw)
From: root <root@dhcp-135-24-192-103.dhcp.avagotech.net>
* The controller firmware sends separate events for NVMe devices and
PCIe switches similar to existing SAS events.
* NVMe device detection, addition and removal are reported by the
firmware through PCIe Topology Change list events.
* The PCIe device state change events are sent when the firmware
detects any abnormal conditions with a NVMe device or switch.
* The enumeration event are sent when the firmware starts PCIe device
enumeration and stops.
* This patch has the code change to handle the events and add/remove
NVMe devices in driver's inventory.

Suganath,
> mpt3sas: SGL to PRP Translation for I/Os to NVMe devices
I'm still confused about this patch.
- I don't understand why you go through all these hoops to decide
whether to use PRPs or IEEE scatterlists. If the firmware translation
is slow, why even bother with the SG format in the first place? Set
the max I/O size to match MDTS and you're done.
- What's the benefit of using SG for regular I/O commands?
- If the unmap translation in firmware is slow, why don't you translate
WRITE SAME/w UNMAP set to DSM DEALLOCATE without requiring
applications to do encapsulated passthrough?
Also make sure you attribute your patches correctly (From: root
<root@dhcp-135-24-192-103.dhcp.avagotech.net>). And you don't need that
long CC: list. Just send the patch series to linux-scsi@vger.kernel.org.
Thanks!

is slow, why even bother with the SG format in the first place? Set

blk_queue_max_hw_sectors(). As of now, we see correct MDTS value is
being set to block layer via VPD page 0xb0 (Block limits VPD page )
response from FW for NVME device.

- What's the benefit of using SG for regular I/O commands?
=> Broadcom's IT Tri-mode HBA hardware has a capability of
translating IEEE SGLs to PRP's only up to ~4 page block size.
If the IO block size is greater than that (along with other condition
described code base_is_prp_possible), driver has to frame the PRP's to
avoid FW intervention. Both the case is a fast path, but for smaller
IO (up to 20K) size will frame IEEE SGL and large IO size will frame
PRP format SGL. Theoretically we want to use h/w capability (to
translate IEEE to PRP) for smaller IO size to leverage h/w capability.
We are investigating if at all we can send all PRP and avoid checks in
driver, but that exercise may take time as we have many different
opinions. We prefer to use existing code as it is stable and in-line
with h/w requirement.

Nobody says we have to use the capability just because the hardware has
it.
Unlike some other operating systems, Linux will only submit I/Os to the
driver that conform to the reported underlying constraints of the
hardware. I fail to understand how letting the HBA firmware translate an
SGL to a PRP for a subset of I/Os could do anything but add latency.
Plus complexity in the hot path of the driver.

It is imperative that the common use case, Linux' discard
infrastructure, is working correctly and is as performant as any
application-driven passthrough workaround.
Unlike SCSI-to-SATA translation you have the benefit of a 1:1 mapping
between UNMAP and DEALLOCATE. I'm not even sure why there would be a
significant performance penalty in the firmware?

And yet patch 4 circumvents that statement by adding support for
encapsulated commands to bypass the FW translation...

<Suganath> In general, h/w constraints are handled. What we missed is
Fast Path h/w
which is not exposed to OS.

<Suganath> Let me explain - NVME device fast path is possible in two ways.
IEEE SGL and PRP SGL. Due to h/w constraint we choose IEEE SGL only for
smaller IO size.
Both above is true h/w Fast Path and no firmware involvement.
> Plus complexity in the hot path of the driver.
<Suganath> Agree with you. We are planning to see if we can keep only
simple Fast
Path using only PRP. It will take some time to finalize as we have to
engage h/w and f/w team. BTW - This area is h/w dependent and we do not
see further changes in this area.

Patch 4 states:
"This encapsulated NVMe command is used by applications to send direct
NVMe commands to NVMe drives or for handling unmap where the translation
at controller/firmware level is having performance issues."

The statement in description of patch 4 is added by mistake, We ll
correct the description and re sending that.

We are working on this, since there is h/w dependent, we are in
discussion with H/W & F/W team and doing experiments. If there is no
impact, and if SGL translation has to be removed, this change has to
go through some phase of testing, before we post it to upstream, since
that is not inline with H/W requirement.
The hardware translation of IEEE SGL to NVMe PRPs has limitation.
We have added the below comment in patch 3 as well:
if a command cannot be translated by hardware then it will go
to firmware and the firmware needs to translate it. And this will
have a performance reduction. To avoid that driver proactively
checks whether the translation will be done in hardware or not,
if not then driver try to translate inside the driver
Current code posted to upstream is inline with hardware requirements
and well tested internally.
SGL vs NVMe PRP building in driver is small sanity check for decision making
and it is not going to change in long run.
Also, Making all PRP buffer may or may not need FW changes (assuming
it is possible.),
we may end up into multiple FW version check.
Since this is main IO path and current driver is following H/W limitation,
we should avoid any changes in this area until and unless change is
universal acceptable in FW (for all type of work load).
Hope this clarifies.

Hi Suganath,

I don't understand how submitting an I/O that is guaranteed to honor the
constraints of the target NVMe drive could possibly cause problems for
the controller firmware. Quite the contrary, it's the best case
scenario.

This is why you need to involve the Linux community early in the design
process and not when your implementation is complete.
We could have told you right away what the correct approach would be for
your Linux driver. And that said approach works for products from other
vendors so we see no compelling reason to deviate from it.
As evidenced by Broadcom disowning the legacy mpt and megaraid drivers,
I will be stuck maintaining this mpt3sas code for a decade or more. Long
after Broadcom has ended official support and moved on to different
ASICs and programming interfaces. Consequently, I am very heavily biased
towards solutions that leverage the shared interfaces provided by the
kernel and that don't have special cases and workarounds inside the
driver.
