Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Define PCIE_RESET_CONFIG_DEVICE_WAIT_MS for the generic 100ms
required after reset before config access (Kevin Xie)
- Define PCIE_T_RRS_READY_MS for the generic 100ms required after
reset before config access (probably should be unified with
PCIE_RESET_CONFIG_DEVICE_WAIT_MS) (Damien Le Moal)
Resource management:
- Rename find_resource() to find_resource_space() to be more
descriptive (Ilpo Järvinen)
- Export find_resource_space() for use by PCI core, which needs to
learn whether there is available space for a bridge window (Ilpo
Järvinen)
- Prevent double counting of resources so window size doesn't grow on
each remove/rescan cycle (Ilpo Järvinen)
- Relax bridge window sizing algorithm so a device doesn't break
simply because it was removed and rescanned (Ilpo Järvinen)
- Evaluate the ACPI PRESERVE_BOOT_CONFIG _DSM in
pci_register_host_bridge() (not acpi_pci_root_create()) so we can
unify it with similar DT functionality (Vidya Sagar)
- Extend use of DT "linux,pci-probe-only" property so it works
per-host bridge as well as globally (Vidya Sagar)
- Unify support for ACPI PRESERVE_BOOT_CONFIG _DSM and the DT
"linux,pci-probe-only" property in pci_preserve_config() (Vidya
Sagar)
Driver binding:

BAR resources (Philipp Stanner)
- Deprecate pcim_iomap_table() because uses like
"pcim_iomap_table()[0]" have no good way to return errors (Philipp
Stanner)

pci_request_region() and similar, which are sometimes managed
depending on whether pcim_enable_device() has been called
previously (Philipp Stanner)
- Reimplement pcim_set_mwi() so it doesn't need to keep store MWI
state (Philipp Stanner)
- Add pcim_intx() for use instead of pci_intx(), which is sometimes

- Detect if a device was removed or replaced during system sleep so
we don't assume a new device is the one that used to be there
(Lukas Wunner)
Virtualization:
- Add an ACS quirk for Broadcom BCM5760X multi-function NIC; it
prevents transactions between functions even though it doesn't
advertise ACS, so the functions can be attached individually via
VFIO (Ajit Khaparde)
Peer-to-peer DMA:
- Add a "pci=config_acs=" kernel command-line parameter to relax

Prior to commit dc6fcaaba5 ("drm/omap: Allow build with
COMPILE_TEST=y"), it was only possible to build the omapdrm driver with
a 4KB page size. After that change, when the PAGE_SIZE is 64KB or
larger, clang points out that the driver has some assumptions around the
page size implicitly by passing PAGE_SIZE to a parameter with a type of
u16:
drivers/gpu/drm/omapdrm/omap_gem.c:758:7: error: implicit conversion from 'unsigned long' to 'u16' (aka 'unsigned short') changes value from 65536 to 0 [-Werror,-Wconstant-conversion]

758 | PAGE_SIZE);

2 errors generated.
As there is a lot of use of a u16 type throughout this driver and it
will only ever be run on hardware that has a 4KB page size, just
restrict compile testing to when the page size is less than 64KB (as no
other issues have been discussed and it keeps compile testing relatively
more available).

When the PCI devres API was introduced to this driver, it was wrongly
assumed that initializing the device with pcim_enable_device() instead of
pci_enable_device() will make all PCI functions managed.
This is wrong and was caused by the quite confusing PCI devres API in which
some, but not all, functions become managed that way.
The function pci_iomap_range() is never managed.
Replace pci_iomap_range() with the managed function pcim_iomap_range().
Fixes: 8558de401b ("drm/vboxvideo: use managed pci functions")

The caching mode for buffer objects with VRAM as a possible
placement was forced to write-combined, regardless of placement.
However, write-combined system memory is expensive to allocate and
even though it is pooled, the pool is expensive to shrink, since
it involves global CPU TLB flushes.
Moreover write-combined system memory from TTM is only reliably
available on x86 and DGFX doesn't have an x86 restriction.
So regardless of the cpu caching mode selected for a bo,
internally use write-back caching mode for system memory on DGFX.
Coherency is maintained, but user-space clients may perceive a
difference in cpu access speeds.
v2:
- Update RB- and Ack tags.
- Rephrase wording in xe_drm.h (Matt Roper)
v3:
- Really rephrase wording.

In Xe, the perf layer allows capture of HW counter streams. These HW
counters are generally performance related but don't have to be necessarily
so. Also, the name "perf" is a carryover from i915 and is not preferred.
Here we propose the name "observation" for this common layer which allows
capture of different types of these counter streams.
v2: Rename observability layer to observation layer (Lucas/Rodrigo)
v3: Rename sysctl file to "observation_paranoid" (Jose)

(cherry picked from commit 320debca1b)
The problem case is as follows:
1. GPU A triggers a gpu ras reset, and GPU A drives
GPU B to also perform a gpu ras reset.
2. After gpu B ras reset started, gpu B queried a DE
data. Since the DE data was queried in the ras reset
thread instead of the page retirement thread, bad
page retirement work would not be triggered. Then
even if all gpu resets are completed, the bad pages
will be cached in RAM until GPU B's bad page retirement
work is triggered again and then saved to eeprom.
This patch can save the bad pages to eeprom in time after gpu
ras reset is completed.
v2:
1. Add the above description to code comments.
2. Reuse existing function.

Why:
If the reg mmMP1_SMN_C2PMSG_90 is being written to during amdgpu driver
load or driver unload, subsequent amdgpu driver load will fail at
smu_hw_init. The default of mmMP1_SMN_C2PMSG_90 register at a clean
environment is 0x1 and if value differs from expected, amdgpu driver
load will fail.
How to fix:
Ignore the initial value in smu response register before the first smu
message is sent,if smc in SMU_FW_INIT state, just proceed further to
send the message. If register holds an unexpected value after smu message
was sent set, smc_state to SMU_FW_HANG state and no further smu messages
will be sent.
v2:
Set SMU_FW_INIT state at the start of smu hw_init/resume.
Check smc_fw_state before sending smu message if in hang state skip
sending message.
Set SMU_FW_HANG only in case unexpected value is detected

Add qxl_bo_pin_and_vmap() that pins and vmaps a buffer object in one
step. Update callers of the regular qxl_bo_vmap(). Fixes a bug where
qxl accesses an unpinned buffer object while it is being moved; such
as with the monitor-description BO. An typical error is shown below.

Commit b33651a5c9 ("drm/qxl: Do not pin buffer objects for vmap")
removed the implicit pin operation from qxl's vmap code. This is the
correct behavior for GEM and PRIME interfaces, but the pin is still
needed for qxl internal operation.
Also add a corresponding function qxl_bo_vunmap_and_unpin() and remove
the old qxl_bo_vmap() helpers.
Future directions: BOs should not be pinned or vmapped unnecessarily.
The pin-and-vmap operation should be removed from the driver and a
temporary mapping should be established with a vmap_local-like helper.
See the client helper drm_client_buffer_vmap_local() for semantics.
v2:
- unreserve BO on errors in qxl_bo_pin_and_vmap() (Dmitry)
