We need a solution to use an Ethernet PHY that is not the first device
on the MDIO bus (device 0 on MDIO bus).
As an example with the i.MX6UL the NXP SOC has 2 Ethernet devices but
only one MDIO bus on which the 2 related PHY are connected but at unique
addresses.

Introduce a new property defining a reserved region:
<low address>:<high address>:<type>.
This will be used to encode reserved IOVA regions.
For instance, in virtio-iommu use case, reserved IOVA regions
will be passed by the machine code to the virtio-iommu-pci
device (an array of those). The type of the reserved region
will match the virtio_iommu_probe_resv_mem subtype value:
- VIRTIO_IOMMU_RESV_MEM_T_RESERVED (0)
- VIRTIO_IOMMU_RESV_MEM_T_MSI (1)
on PC/Q35 machine, this will be used to inform the
virtio-iommu-pci device it should bypass the MSI region.
The reserved region will be: 0xfee00000:0xfeefffff:1.
On ARM, we can declare the ITS MSI doorbell as an MSI
region to prevent MSIs from being mapped on guest side.

This patch implements the PROBE request. At the moment,
only THE RESV_MEM property is handled. The first goal is
to report iommu wide reserved regions such as the MSI regions
set by the machine code. On x86 this will be the IOAPIC MSI
region, [0xFEE00000 - 0xFEEFFFFF], on ARM this may be the ITS
doorbell.
In the future we may introduce per device reserved regions.
This will be useful when protecting host assigned devices
which may expose their own reserved regions

Hi Eric -- Coverity points out (CID 1430180) that this new case
has neither a 'break' nor a /* fallthrough */ comment. Which is correct?

When translating an address we need to check if it belongs to
a reserved virtual address range. If it does, there are 2 cases:
- it belongs to a RESERVED region: the guest should neither use
this address in a MAP not instruct the end-point to DMA on
them. We report an error
- It belongs to an MSI region: we bypass the translation.

The machine may need to pass reserved regions to the
virtio-iommu-pci device (such as the MSI window on x86
or the MSI doorbells on ARM).
So let's add an array of Interval properties.
Note: if some reserved regions are already set by the
machine code - which should be the case in general -,
the length of the property array is already set and
prevents the end-user from modifying them. For example,
attempting to use:
-device virtio-iommu-pci,\
len-reserved-regions=1,reserved-regions[0]=0xfee00000:0xfeefffff:1
would result in the following error message:
qemu-system-aarch64: -device virtio-iommu-pci,addr=0xa,
len-reserved-regions=1,reserved-regions[0]=0xfee00000:0xfeefffff:1:
array size property len-reserved-regions may not be set more than once
Otherwise, for example, adding two reserved regions is achieved
using the following options:
-device virtio-iommu-pci,addr=0xa,len-reserved-regions=2,\
reserved-regions[0]=0xfee00000:0xfeefffff:1,\
reserved-regions[1]=0x1000000:100ffff:1

At the moment the virtio-iommu translates MSI transactions.
This behavior is inherited from ARM SMMU. The virt machine
code knows where the guest MSI doorbells are so we can easily
declare those regions as VIRTIO_IOMMU_RESV_MEM_T_MSI. With that
setting the guest will not map MSIs through the IOMMU and those
transactions will be simply bypassed.
Depending on which MSI controller is in use (ITS or GICV2M),
we declare either:
- the ITS interrupt translation space (ITS_base + 0x10000),
containing the GITS_TRANSLATOR or
- The GICV2M single frame, containing the MSI_SETSP_NS register.

Where is "len-reserved-regions" declared?
Since qdev_prop_set_uint32() uses &error_abort, isn't this call
aborting the process? I am confused how this code path is exercised,
what am I missing?

The call path is:
qdev_prop_set_uint32 ->
object_property_set_int ->
object_property_set_qobject ->
object_property_set ->
object_property_find_err
So QEMU should abort displaying:
"Property 'virtio-iommu-pci.len-reserved-regions' not found".

DEFINE_PROP_ARRAY("reserved-regions", ...)
does this. For an array property "foo" the machinery creates an integer
property "foo-len", which must be set first. Setting that
then creates properties "foo[0]", "foo[1]", ... which can be set.

Oh indeed now I see the array prefix:
#define PROP_ARRAY_LEN_PREFIX "len-"
Not obvious to realize while grepping.
Thanks for the quick answer!

On ARMv7 & ARMv8 some load/store instructions might trigger a data abort
exception with no valid ISS info to be decoded. The lack of decode info
makes it at least tricky to emulate those instruction which is one of the
(many) reasons why KVM will not even try to do so.
Add support for handling those by requesting KVM to inject external
dabt into the quest.

Injecting external data abort through KVM might trigger
an issue on kernels that do not get updated to include the KVM fix.
For those and aarch32 guests, the injected abort gets misconfigured
to be an implementation defined exception. This leads to the guest
repeatedly re-running the faulting instruction.
Add support for handling that case.

The flash device is exclusively for the host-controlled firmware, so
we should not expose it to the OS. Exposing it risks the OS messing
with it, which could break firmware runtime services and surprise the
OS when all its changes disappear after reboot.
As firmware needs the device and uses DT, we leave the device exposed
there. It's up to firmware to remove the nodes from DT before sending
it on to the OS. However, there's no need to force firmware to remove
tables from ACPI (which it doesn't know how to do anyway), so we
simply don't add the tables in the first place. But, as we've been
adding the tables for quite some time and don't want to change the
default hardware exposed to versioned machines, then we only stop
exposing the flash device tables for 5.1 and later machine types.

The temp that gets assigned to clean_addr has been allocated with
new_tmp_a64, which means that it will be freed at the end of the
instruction. Freeing it earlier leads to assertion failure.
The loop creates a complication, in which we allocate a new local
temp, which does need freeing, and the final code path is shared
between the loop and non-loop.
Fix this complication by adding new_tmp_a64_local so that the new
local temp is freed at the end, and can be treated exactly like
the non-loop path.

In bcm2835_fb_mbox_push(), Coverity complains (CID 1429989) that we
pass a pointer to a local struct to another function without
initializing all its fields. This is a real bug:
bcm2835_fb_reconfigure() copies the whole of our new BCM2385FBConfig
struct into s->config, so any fields we don't initialize will corrupt
the state of the device.
Copy the two fields which we don't want to update (pixo and alpha)
from the existing config so we don't accidentally change them.

The spitz board has been around a long time, and still has a fair number
of hard-coded tab characters in it. We're about to do some work on
this source file, so start out by expanding out the tabs.
This commit is a pure whitespace only change.

To: qemu-devel
For the four Spitz-family machines (akita, borzoi, spitz, terrier)
create a proper abstract class SpitzMachineClass which encapsulates
the common behaviour, rather than having them all derive directly
from TYPE_MACHINE:
* instead of each machine class setting mc->init to a wrapper
function which calls spitz_common_init() with parameters,
put that data in the SpitzMachineClass and make spitz_common_init
the SpitzMachineClass machine-init function
* move the settings of mc->block_default_type and
mc->ignore_memory_transaction_failures into the SpitzMachineClass
class init rather than repeating them in each machine's class init
(The motivation is that we're going to want to keep some state in
the SpitzMachineState so we can connect GPIOs between devices created
in one sub-function of the machine init to devices created in a
different sub-function.)

SSI devices and the SCPs, so we want to keep hold of a pointer to
those; putting the MPU into the struct allows us to pass just
one thing to spitz_ssp_attach() rather than two.
We have to retain the setting of the global "max1111" variable
for the moment as it is used in spitz_adc_temp_on(); later in
this series of commits we will be able to remove it.

Keep pointers to scp0, scp1 in SpitzMachineState, and just pass
that to spitz_scoop_gpio_setup().
(We'll want to use some of the other fields in SpitzMachineState
in that function in the next commit.)

Currently the Spitz board uses a nasty hack for the GPIO lines
that pass "bit5" and "power" information to the LCD controller:
the lcdtg realize function sets a global variable to point to
the instance it just realized, and then the functions spitz_bl_power()
and spitz_bl_bit5() use that to find the device they are changing
the internal state of. There is a comment reading:
FIXME: Implement GPIO properly and remove this hack.
which was added in 2009.

Add some QOM properties to the max111x ADC device to allow the
initial values to be configured. Currently this is done by
board code calling max111x_set_input() after it creates the
device, which doesn't work on system reset.
This requires us to implement a reset method for this device,
so while we're doing that make sure we reset the other parts
of the device state.

The max111x is a proper qdev device; we can use dc->vmsd rather than
directly calling vmstate_register().
It's possible that this is a migration compat break, but the only
boards that use this device are the spitz-family ('akita', 'borzoi',
'spitz', 'terrier').

Add an ssi_realize_and_unref(), for the benefit of callers
who want to be able to create an SSI device, set QOM properties
on it, and then do the realize-and-unref afterwards.
The API works on the same principle as the recently added
qdev_realize_and_undef(), sysbus_realize_and_undef(), etc.

Use the new max111x qdev properties to set the initial input
values rather than calling max111x_set_input(); this means that
on system reset the inputs will correctly return to their initial
values.

The max111x ADC device model allows other code to set the level on
the 8 ADC inputs using the max111x_set_input() function. Replace
this with generic qdev GPIO inputs, which also allow inputs to be set
to arbitrary values.
Using GPIO lines will make it easier for board code to wire things
up, so that if device A wants to set the ADC input it doesn't need to
have a direct pointer to the max111x but can just set that value on
its output GPIO, which is then wired up by the board to the
appropriate max111x input.

Create a header file for the hw/misc/max111x device, in the
usual modern style for QOM devices:
* definition of the TYPE_ constants and macros
* definition of the device's state struct so that it can
be embedded in other structs if desired
* documentation of the interface
This allows us to use TYPE_MAX_1111 in the spitz.c code rather
than the string "max1111".

To: qemu-devel
Currently we have a free-floating set of IRQs and a function
spitz_out_switch() which handle some miscellaneous GPIO lines for the
spitz board. Encapsulate this behaviour in a simple QOM device.
At this point we can finally remove the 'max1111' global, because the
ADC battery-temperature value is now handled by the misc-gpio device
writing the value to its outbound "adc-temp" GPIO, which the board
code wires up to the appropriate inbound GPIO line on the max1111.
This commit also fixes Coverity issue CID 1421913 (which pointed out
that the 'outsignals' in spitz_scoop_gpio_setup() were leaked),
because it removes the use of the qemu_allocate_irqs() API from this
code entirely.

Instead of logging guest accesses to invalid register offsets in this
device using zaurus_printf() (which just prints to stderr), use the
usual qemu_log_mask(LOG_GUEST_ERROR,...).
Since this was the only use of the zaurus_printf() macro outside
spitz.c, we can move the definition of that macro from sharpsl.h
to spitz.c.

Instead of using printf() for logging guest accesses to invalid
register offsets in the pxa2xx PIC device, use the usual
qemu_log_mask(LOG_GUEST_ERROR,...).
This was the only user of the REG_FMT macro in pxa.h, so we can
remove that.

The QOM types "spitz-lcdtg" and "corgi-ssp" are missing the
usual QOM TYPE and casting macros; provide and use them.
In particular, we can safely use the QOM cast macros instead of
FROM_SSI_SLAVE() because in both cases the 'ssidev' field of
the instance state struct is the first field in it.

The FROM_SSI_SLAVE() macro predates QOM and is used as a typesafe way
to cast from an SSISlave* to the instance struct of a subtype of
TYPE_SSI_SLAVE. Switch to using the QOM cast macros instead, which
have the same effect (by writing the QOM macros if the types were
previously missing them.)
(The FROM_SSI_SLAVE() macro allows the SSISlave member of the
subtype's struct to be anywhere as long as it is named "ssidev",
whereas a QOM cast macro insists that it is the first thing in the
subtype's struct. This is true for all the types we convert here.)
This removes all the uses of FROM_SSI_SLAVE() so we can delete the
definition.

Deprecate our TileGX target support:
* we have no active maintainer for it
* it has had essentially no contributions (other than tree-wide cleanups
and similar) since it was first added
* the Linux kernel dropped support in 2018, as has glibc
Note the deprecation in the manual, but don't try to print a warning
when QEMU runs -- printing unsuppressable messages is more obtrusive
for linux-user mode than it would be for system-emulation mode, and
it doesn't seem worth trying to invent a new suppressible-error
system for linux-user just for this.
