Mark xe driver as BROKEN if kernel page size is not 4kB
This driver, for the time being, assumes that the kernel page size is 4kB,
so it fails on loong64 and aarch64 with 16kB pages, and ppc64el with 64kB
pages.

drm/xe: Support for I2C attached MCUs
Adding adaption/glue layer where the I2C host adapter
(Synopsys DesignWare I2C adapter) and the I2C clients (the
microcontroller units) are enumerated.

The microcontroller units (MCU) that are attached to the GPU
depend on the OEM. The initially supported MCU will be the
Add-In Management Controller (AMC).

f86ad0ed62 drm/gpusvm, drm/pagemap: Move migration functionality to drm_pagemap
The migration functionality and track-keeping of per-pagemap VRAM
mapped to the CPU mm is not per GPU_vm, but rather per pagemap.
This is also reflected by the functions not needing the drm_gpusvm
structures. So move to drm_pagemap.

With this, drm_gpusvm shouldn't really access the page zone-device-data
since its meaning is internal to drm_pagemap. Currently it's used to
reject mapping ranges backed by multiple drm_pagemap allocations.
For now, make the zone-device-data a void pointer.

Alter the interface of drm_gpusvm_migrate_to_devmem() to ensure we don't
pass a gpusvm pointer.

Rename CONFIG_DRM_XE_DEVMEM_MIRROR to CONFIG_DRM_XE_PAGEMAP.

Matt is listed as author of this commit since he wrote most of the code,
and it makes sense to retain his git authorship.
Thomas mostly moved the code around.

v3:
- Kerneldoc fixes (CI)
- Don't update documentation about how the drm_pagemap
  migration should be interpreted until upcoming
  patches where the functionality is implemented.
  (Matt Brost)
v4:
- More kerneldoc fixes around timeslice_ms
  (Himal Ghimiray, Matt Brost)
v6:
- Fix an uninitialized pagemap pointer (CI)

2182f358fb drm/xe/vsec: fix CONFIG_INTEL_VSEC dependency
The XE driver can be built with or without VSEC support, but fails to link as
built-in if vsec is in a loadable module:

x86_64-linux-ld: vmlinux.o: in function `xe_vsec_init':
(.text+0x1e83e16): undefined reference to `intel_vsec_register'

The normal fix for this is to add a 'depends on INTEL_VSEC || !INTEL_VSEC',
forcing XE to be a loadable module as well, but that causes a circular
dependency:

        symbol DRM_XE depends on INTEL_VSEC
        symbol INTEL_VSEC depends on X86_PLATFORM_DEVICES
        symbol X86_PLATFORM_DEVICES is selected by DRM_XE

The problem here is selecting a symbol from another subsystem, so change
that as well and rephrase the 'select' into the corresponding dependency.
Since X86_PLATFORM_DEVICES is 'default y', there is no change to
defconfig builds here.

Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Print the actual delay time in pci_bridge_wait_for_secondary_bus()
     instead of assuming it was 1000ms (Wilfred Mallawa)

   - Revert 'iommu/amd: Prevent binding other PCI drivers to IOMMU PCI
     devices', which broke resume from system sleep on AMD platforms and
     has been fixed by other commits (Lukas Wunner)

  Resource management:

   - Remove mtip32xx use of pcim_iounmap_regions(), which is deprecated
     and unnecessary (Philipp Stanner)

   - Remove pcim_iounmap_regions() and pcim_request_region_exclusive()
     and related flags since all uses have been removed (Philipp
     Stanner)

   - Rework devres 'request' functions so they are no longer 'hybrid',
     i.e., their behavior no longer depends on whether
     pcim_enable_device or pci_enable_device() was used, and remove
     related code (Philipp Stanner)

   - Warn (not BUG()) about failure to assign optional resources (Ilpo
     Järvinen)

  Error handling:

   - Log the DPC Error Source ID only when it's actually valid (when
     ERR_FATAL or ERR_NONFATAL was received from a downstream device)
     and decode into bus/device/function (Bjorn Helgaas)

   - Determine AER log level once and save it so all related messages
     use the same level (Karolina Stolarek)

   - Use KERN_WARNING, not KERN_ERR, when logging PCIe Correctable
     Errors (Karolina Stolarek)

   - Ratelimit PCIe Correctable and Non-Fatal error logging, with sysfs
     controls on interval and burst count, to avoid flooding logs and
     RCU stall warnings (Jon Pan-Doh)

  Power management:

   - Increment PM usage counter when probing reset methods so we don't
     try to read config space of a powered-off device (Alex Williamson)

   - Set all devices to D0 during enumeration to ensure ACPI opregion is
     connected via _REG (Mario Limonciello)

  Power control:

   - Rename pwrctrl Kconfig symbols from 'PWRCTL' to 'PWRCTRL' to match
     the filename paths. Retain old deprecated symbols for
     compatibility, except for the pwrctrl slot driver
     (PCI_PWRCTRL_SLOT) (Johan Hovold)

   - When unregistering pwrctrl, cancel outstanding rescan work before
     cleaning up data structures to avoid use-after-free issues (Brian
     Norris)

  Bandwidth control:

   - Simplify link bandwidth controller by replacing the count of Link
     Bandwidth Management Status (LBMS) events with a PCI_LINK_LBMS_SEEN
     flag (Ilpo Järvinen)

   - Update the Link Speed after retraining, since the Link Speed may
     have changed (Ilpo Järvinen)

  PCIe native device hotplug:

   - Ignore Presence Detect Changed caused by DPC.

     pciehp already ignores Link Down/Up events caused by DPC, but on
     slots using in-band presence detect, DPC causes a spurious Presence
     Detect Changed event (Lukas Wunner)

   - Ignore Link Down/Up caused by Secondary Bus Reset.

     On hotplug ports using in-band presence detect, the reset causes a
     Presence Detect Changed event, which mistakenly caused teardown and
     re-enumeration of the device. Drivers may need to annotate code
     that resets their device (Lukas Wunner)

  Virtualization:

   - Add an ACS quirk for Loongson Root Ports that don't advertise ACS
     but don't allow peer-to-peer transactions between Root Ports; the
     quirk allows each Root Port to be in a separate IOMMU group (Huacai
     Chen)

  Endpoint framework:

   - For fixed-size BARs, retain both the actual size and the possibly
     larger size allocated to accommodate iATU alignment requirements
     (Jerome Brunet)

   - Simplify ctrl/SPAD space allocation and avoid allocating more space
     than needed (Jerome Brunet)

   - Correct MSI-X PBA offset calculations for DesignWare and Cadence
     endpoint controllers (Niklas Cassel)

   - Align the return value (number of interrupts) encoding for
     pci_epc_get_msi()/pci_epc_ops::get_msi() and
     pci_epc_get_msix()/pci_epc_ops::get_msix() (Niklas Cassel)

   - Align the nr_irqs parameter encoding for
     pci_epc_set_msi()/pci_epc_ops::set_msi() and
     pci_epc_set_msix()/pci_epc_ops::set_msix() (Niklas Cassel)

  Common host controller library:

   - Convert pci-host-common to a library so platforms that don't need
     native host controller drivers don't need to include these helper
     functions (Manivannan Sadhasivam)

  Apple PCIe controller driver:

   - Extract ECAM bridge creation helper from pci_host_common_probe() to
     separate driver-specific things like MSI from PCI things (Marc
     Zyngier)

   - Dynamically allocate RID-to_SID bitmap to prepare for SoCs with
     varying capabilities (Marc Zyngier)

   - Skip ports disabled in DT when setting up ports (Janne Grunau)

   - Add t6020 compatible string (Alyssa Rosenzweig)

   - Add T602x PCIe support (Hector Martin)

   - Directly set/clear INTx mask bits because T602x dropped the
     accessors that could do this without locking (Marc Zyngier)

   - Move port PHY registers to their own reg items to accommodate
     T602x, which moves them around; retain default offsets for existing
     DTs that lack phy%d entries with the reg offsets (Hector Martin)

   - Stop polling for core refclk, which doesn't work on T602x and the
     bootloader has already done anyway (Hector Martin)

   - Use gpiod_set_value_cansleep() when asserting PERST# in probe
     because we're allowed to sleep there (Hector Martin)

  Cadence PCIe controller driver:

   - Drop a runtime PM 'put' to resolve a runtime atomic count underflow
     (Hans Zhang)

   - Make the cadence core buildable as a module (Kishon Vijay Abraham I)

   - Add cdns_pcie_host_disable() and cdns_pcie_ep_disable() for use by
     loadable drivers when they are removed (Siddharth Vadapalli)

  Freescale i.MX6 PCIe controller driver:

   - Apply link training workaround only on IMX6Q, IMX6SX, IMX6SP
     (Richard Zhu)

   - Remove redundant dw_pcie_wait_for_link() from
     imx_pcie_start_link(); since the DWC core does this, imx6 only
     needs it when retraining for a faster link speed (Richard Zhu)

   - Toggle i.MX95 core reset to align with PHY powerup (Richard Zhu)

   - Set SYS_AUX_PWR_DET to work around i.MX95 ERR051624 erratum: in
     some cases, the controller can't exit 'L23 Ready' through Beacon or
     PERST# deassertion (Richard Zhu)

   - Clear GEN3_ZRXDC_NONCOMPL to work around i.MX95 ERR051586 erratum:
     controller can't meet 2.5 GT/s ZRX-DC timing when operating at 8
     GT/s, causing timeouts in L1 (Richard Zhu)

   - Wait for i.MX95 PLL lock before enabling controller (Richard Zhu)

   - Save/restore i.MX95 LUT for suspend/resume (Richard Zhu)

  Mobiveil PCIe controller driver:

   - Return bool (not int) for link-up check in
     mobiveil_pab_ops.link_up() and layerscape-gen4, mobiveil (Hans
     Zhang)

  NVIDIA Tegra194 PCIe controller driver:

   - Create debugfs directory for 'aspm_state_cnt' only when
     CONFIG_PCIEASPM is enabled, since there are no other entries (Hans
     Zhang)

  Qualcomm PCIe controller driver:

   - Add OF support for parsing DT 'eq-presets-<N>gts' property for lane
     equalization presets (Krishna Chaitanya Chundru)

   - Read Maximum Link Width from the Link Capabilities register if DT
     lacks 'num-lanes' property (Krishna Chaitanya Chundru)

   - Add Physical Layer 64 GT/s Capability ID and register offsets for
     8, 32, and 64 GT/s lane equalization registers (Krishna Chaitanya
     Chundru)

   - Add generic dwc support for configuring lane equalization presets
     (Krishna Chaitanya Chundru)

   - Add DT and driver support for PCIe on IPQ5018 SoC (Nitheesh Sekar)

  Renesas R-Car PCIe controller driver:

   - Describe endpoint BAR 4 as being fixed size (Jerome Brunet)

   - Document how to obtain R-Car V4H (r8a779g0) controller firmware
     (Yoshihiro Shimoda)

  Rockchip PCIe controller driver:

   - Reorder rockchip_pci_core_rsts because

e4931f8be3 drm/xe/vsec: fix CONFIG_INTEL_VSEC dependency
The XE driver can be built with or without VSEC support, but fails to link as
built-in if vsec is in a loadable module:

x86_64-linux-ld: vmlinux.o: in function `xe_vsec_init':
(.text+0x1e83e16): undefined reference to `intel_vsec_register'

The normal fix for this is to add a 'depends on INTEL_VSEC || !INTEL_VSEC',
forcing XE to be a loadable module as well, but that causes a circular
dependency:

        symbol DRM_XE depends on INTEL_VSEC
        symbol INTEL_VSEC depends on X86_PLATFORM_DEVICES
        symbol X86_PLATFORM_DEVICES is selected by DRM_XE

The problem here is selecting a symbol from another subsystem, so change
that as well and rephrase the 'select' into the corresponding dependency.
Since X86_PLATFORM_DEVICES is 'default y', there is no change to
defconfig builds here.

8fe743b5eb PCI: Add CONFIG_MMU dependency
It turns out that there are no platforms that have PCI but don't have an
MMU, so adding a Kconfig dependency on CONFIG_PCI simplifies build testing
kernels for those platforms a lot, and avoids a lot of inadvertent build
regressions.

Add a dependency for CONFIG_PCI and remove all the ones for PCI specific
device drivers that are currently marked not having it.

There are a few platforms that have an optional MMU, but they usually
cannot have PCI at all. The one exception is Coldfire MCF54xx, but this is
mainly for historic reasons, and anyone using those chips should really use
the MMU these days.

drm: handle HAS_IOPORT dependencies
In a future patch HAS_IOPORT=n will disable inb()/outb() and friends at
compile time. We thus need to add HAS_IOPORT as dependency for those
drivers using them. In the bochs driver there is optional MMIO support
detected at runtime, warn if this isn't taken when HAS_IOPORT is not
defined.

There is also a direct and hard coded use in cirrus.c which according to
the comment is only necessary during resume.  Let's just skip this as
for example s390 which doesn't have I/O port support also doesen't
support suspend/resume.

drm/xe: select DRM_DISPLAY_DSC_HELPER
The Xe driver shares display code with the i915 driver, pulling in the
dependency on the DSC helpers this way. However when working on
separating DRM_DISPLAY_DSC_HELPER this was left unnoticed. Add missing
dependency.

Revert "drm: Switch DRM_DISPLAY_HELPER to depends on"
This reverts commit e075e496f5, as helper
code should always be selected by the driver that needs it, for the
convenience of the final user configuring a kernel.

The user who configures a kernel should not need to know which helpers
are needed for the driver he is interested in.  Making a driver depend
on helper code means that the user needs to know which helpers to enable
first, which is very user-unfriendly.

81e058a3e7 drm/xe: Introduce helper to populate userptr
Introduce a helper function xe_userptr_populate_range to populate

drm: Switch DRM_DISPLAY_HDMI_HELPER to depends on

Indeed, select doesn't select a dependency's dependencies, and thus

We do this by recompiling i915/display code twice.
Now that i915 has been adapted to support the Xe build, we can add
the xe/display support.

This initial work is a collaboration of many people and unfortunately
this squashed patch won't fully honor the proper credits.
But let's try to add a few from the squashed patches:

08987a8b68 drm/xe: Fix build with KUNIT=m
Due to the current integration between "live" xe kunit tests and kunit,
it's not possible to have a build with the following combination:

	CONFIG_DRM_XE=y
	CONFIG_KUNIT=m

... even if kconfig doesn't block it. The reason for the failure is that
some compilation units are pulled in xe.ko:

	drivers/gpu/drm/xe/xe_bo.c:#include "tests/xe_bo.c"
	drivers/gpu/drm/xe/xe_dma_buf.c:#include "tests/xe_dma_buf.c"
	drivers/gpu/drm/xe/xe_migrate.c:#include "tests/xe_migrate.c"
	drivers/gpu/drm/xe/xe_pci.c:#include "tests/xe_pci.c"

Those files shouldn't use symbols from kunit, which should be reserved
to the tests/*_test.c files. Detangling this dependency doesn't seem
very straightforward, so fix the immediate issue instructing kconfig to
block the problematic configuration.

d490ecf577 drm/xe: Rework xe_exec and the VM rebind worker to use the drm_exec helper
Replace the calls to ttm_eu_reserve_buffers() by using the drm_exec
helper instead. Also make sure the locking loop covers any calls to
xe_bo_validate() / ttm_bo_validate() so that these function calls may
easily benefit from being called from within an unsealed locking
transaction and may thus perform blocking dma_resv locks in the future.

For the unlock we remove an assert that the vm->rebind_list is empty
when locks are released. Since if the error path is hit with a partly
locked list, that assert may no longer hold true we chose to remove it.

v3:
- Don't accept duplicate bo locks in the rebind worker.
v5:
- Loop over drm_exec objects in reverse when unlocking.
v6:
- We can't keep the WW ticket when retrying validation on OOM. Fix.

V12:
   - Rebase
V11:
   - Make engine_get_prop_minmax and enforce_sched_limit static - Matt
   - use enum in place of string in engine_get_prop_minmax - Matt
   - no need to use enforce_sched_limit or no need to filter min/max
     per user type in sysfs - Matt
V10:
   - Add kernel doc for non-static func
   - Make helper to get min/max for range validation - Matt
   - Filter min/max per user type
V9 :
   - Rebase to use s/xe_engine/xe_hw_engine/ - Matt
V8 :
   - fix enforce_sched_limit and avoid code duplication - Niranjana
   - Make sure min < max - Niranjana
V7 :
   - Rebase to replace hw engine with eclass interface
   - return EINVAL in place of EPERM
   - Use some APIs to avoid code duplication
V6 :
   - Rebase changes to reflect per engine class props interface - MattB

   - Remove MAX_SCHED_TIMEOUT check as range validation is enough
V5 :
   - Rebase to resolve conflicts - CI
V4 :
   - Rebase
   - Update commit to reflect tile addition
   - Use XE_HW macro directly as they are already filtered
     for CONFIG checks - Niranjana
   - Add CONFIG for enable/disable min/max limitation
     on elevated user. Default is enable - Matt/Joonas
V3 :
   - Resolve CI hooks warning for kernel-doc

b06d47be7c drm/xe: Port Xe to GPUVA
Rather than open coding VM binds and VMA tracking, use the GPUVA
library. GPUVA provides a common infrastructure for VM binds to use mmap
/ munmap semantics and support for VK sparse bindings.

The concepts are:

1) xe_vm inherits from drm_gpuva_manager
2) xe_vma inherits from drm_gpuva
3) xe_vma_op inherits from drm_gpuva_op
4) VM bind operations (MAP, UNMAP, PREFETCH, UNMAP_ALL) call into the
GPUVA code to generate an VMA operations list which is parsed, committed,
and executed.

v2 (CI): Add break after default in case statement.
v3: Rebase
v4: Fix some error handling
v5: Use unlocked version VMA in error paths
v6: Rebase, address some review feedback mainly Thomas H
v7: Fix compile error in xe_vma_op_unwind, address checkpatch

e799485044 drm/xe: Introduce the dev_coredump infrastructure.
The goal is to use devcoredump infrastructure to report error states
captured at the crash time.

The error state will contain useful information for GPU hang debug, such
as INSTDONE registers and the current buffers getting executed, as well
as any other information that helps user space and allow later replays of
the error.

The proposal here is to avoid a Xe only error_state like i915 and use
a standard dev_coredump infrastructure to expose the error state.

For our own case, the data is only useful if it is a snapshot of the
time when the GPU crash has happened, since we reset the GPU immediately
after and the registers might have changed. So the proposal here is to
have an internal snapshot to be printed out later.

Also, usually a subsequent GPU hang can be only a cause of the initial
one. So we only save the 'first' hang. The dev_coredump has a delayed
work queue where it remove the coredump and free all the data within a
few moments of the error. When that happens we also reset our capture
state and allow further snapshots.

Right now this infra only print out the time of the hang. More information
will be migrated here on subsequent work. Also, in order to organize the
dump better, the goal is to propose dev_coredump changes itself to allow
multiple files and different controls. But for now we start Xe usage of
it without any dependency on dev_coredump core changes.

v2: Add dma_fence annotation for capture that might happen during long
    running. (Thomas and Matt)
    Use xe->drm.primary->index on drm_info msg. (Jani)
v3: checkpatch fixes
v4: Fix building and locking issues found by Francois.
    Actually let's kill all of the locking in here. gt_reset serialization
    already guarantee that there will be only one capture at the same time.
    Also, the devcoredump has its own locking to protect the free and reads
    and drivers don't need to duplicate it.
    Besides this, the dma_fence locking was pushed to a following patch
    since it is not needed in this one.
    Fix a use after free identified by KASAN: Do not stash the faulty_engine
    since that will be freed somewhere else.
v5: Fix Uptime - ktime_get_boottime actually returns the Uptime. (Francois)
