58548b9110 drm/xe: Defer gt->mmio initialization until after multi-tile setup
With the recent xe_mmio redesign, tiles and GTs each have their own MMIO
accessor, with the GT inheriting some of the information (such as the
iomap pointer) from their containing tile.  Given that non-root tiles
get initialized later than the root tile (and currently after the point
at which GT MMIO is initialized for _all_ GTs), we wind up incorrectly
inheriting uninitialized pointers for the initialization of GT MMIO for
GTs that reside on non-root tiles.  This causes a driver crash on
multi-tile PVC platforms.

With the general xe_mmio redesign, it's now only necessary to do the
GT-level MMIO setup before the point we start reading/writing GT
registers.  Move initialization of gt->mmio out of xe_info_init (which
runs before non-root tiles are initialized) and to the beginning of
where we start actually accessing the GTs themselves.

The high-level initialization flow now boils down to:
 - General device init, software-only setup
 - (no register access possible yet)
 - Root tile initialization
 - (access to device/tile0 registers possible via xe_root_tile_mmio())
 - Initialization of non-root tiles
 - (access to any tile's registers possible via tile->mmio)
 - GT MMIO initialization, inheriting iomap from each GT's tile
 - (access to any GT's registers possible via gt->mmio)

501d799a47 drm/xe: Wire up device shutdown handler
The system is turning off, and we should probably put the device
in a safe power state. We don't need to evict VRAM or suspend running
jobs to a safe state, as the device is rebooted anyway.

This does not imply the system is necessarily reset, as we can
kexec into a new kernel. Without shutting down, things like
USB Type-C may mysteriously start failing.

3b1592fb78 drm/xe/lnl: Apply Wa_22019338487
This WA requires us to limit media GT frequency requests to a certain
cap value during driver load. Freq limits are restored after load
completes, so perf will not be affected during normal operations.

During normal driver operation, this WA requires dummy writes to media
offset 0x380D8C after every ~63 GGTT writes. This will ensure completion
of the LMEM writes originating from Gunit.

During driver unload(before FLR), the WA requires that we set requested
frequency to the cap value again.

v3: Do not use WA number in function name. Call WA wrapper from xe_device.
Rename some variables, check for locks in the correct function (Rodrigo).
Ensure reset path is also covered for this WA.

v4: Fix BAT failure

v5: Add a function pointer for ggtt_ops (Michal W)

1c4324793e Revert "drm/xe: make gt_remove use devm"
This reverts commit cd506a33b0.

The gt_remove function was explicitly added as part of the remove flow
instead of using drmm/devm automatic cleanup due to it being illegal
to remove a component after the driver has been detached from the pci
device; the GSC proxy component is removed as part of gt_remove, so we
need to do it in the pci cleanup flow. The function already has a
comment above it to explain this.

Note that the change to use the devm also caused an invalid pointer
deref in the gsc_proxy unbind function, but I didn't bother to debug
which pointer was bad since we shouldn't be calling the unbind that
late anyway and this revert fixes it.

Both issue were not seen in CI because the GSC loading is temporarily
disabled due to a critical bug, which means we're not binding the
component.

baa1486552 drm/xe: Cache data about user-visible engines
gt->info.engine_mask used to indicate the available engines, but that
is not always true anymore: some engines are reserved to kernel and some
may be exposed as a single engine (e.g. with ccs_mode).

Runtime changes only happen when no clients exist, so it's safe to cache
the list of engines in the gt and update that when it's needed. This
will help implementing per client engine utilization so this (mostly
constant) information doesn't need to be re-calculated on every query.

997a55caa1 drm/xe/gsc: Initialize GSC proxy
The GSC uC needs to communicate with the CSME to perform certain
operations. Since the GSC can't perform this communication directly on
platforms where it is integrated in GT, the graphics driver needs to
transfer the messages from GSC to CSME and back. The proxy flow must be
manually started after the GSC is loaded to signal to GSC that we're
ready to handle its messages and allow it to query its init data from
CSME.

Note that the component must be removed before the pci_remove call
completes, so we can't use a drmm helper for it and we need to instead
perform the cleanup as part of the removal flow.

v2: add function documentation, more targeted memory clear, clearer logs
and variable names (Alan)

Ideally this header could be included without the CONFIG_FAULT_INJECTION

So, let's temporary workaround this by moving this below and including

Another solution would be us including the linux/types.h as well, but
this creates unnecessary cases.

08dea76745 drm/xe: Move migration from GT to tile
Migration primarily focuses on the memory associated with a tile, so it
makes more sense to track this at the tile level (especially since the
driver was already skipping migration operations on media GTs).

Note that the blitter engine used to perform the migration always lives
in the tile's primary GT today.  In theory that could change if media
GTs ever start including blitter engines in the future, but we can
extend the design if/when that happens in the future.

v2:
 - Fix kunit test build
 - Kerneldoc parameter name update
v3:
 - Removed leftover prototype for removed function.  (Gustavo)
 - Remove unrelated / unwanted error handling change.  (Gustavo)

ebd288cba7 drm/xe: Move VRAM from GT to tile
On platforms with VRAM, the VRAM is associated with the tile, not the
GT.

v2:
 - Unsquash the GGTT handling back into its own patch.
 - Fix kunit test build
v3:
 - Tweak the "FIXME" comment to clarify that this function will be
   completely gone by the end of the series.  (Lucas)
v4:
 - Move a few changes that were supposed to be part of the GGTT patch
   back to that commit.  (Gustavo)
v5:
 - Kerneldoc parameter name fix.

f79ee3013a drm/xe: Add backpointer from gt to tile
Rather than a backpointer to the xe_device, a GT should have a
backpointer to its tile (which can then be used to lookup the device if
necessary).

The gt_to_xe() helper macro (which moves from xe_gt.h to xe_gt_types.h)
can and should still be used to jump directly from an xe_gt to
xe_device.

v2:
 - Fix kunit test build
 - Move a couple changes to the previous patch. (Lucas)

8846ffb457 drm/xe: Allow const propagation in gt_to_xe()
Replace the inline function with a _Generic() so gt_to_xe() can work
with a const struct xe_gt*, which leads to a const struct xe *.
This allows a const gt being passed around and when the xe device is
needed, compiler won't issue a warning that calling gt_to_xe() would
discard the const. Rather, just propagate the const to the xe pointer
being returned.

dd08ebf6c3 drm/xe: Introduce a new DRM driver for Intel GPUs
Xe, is a new driver for Intel GPUs that supports both integrated and
discrete platforms starting with Tiger Lake (first Intel Xe Architecture).

The code is at a stage where it is already functional and has experimental
support for multiple platforms starting from Tiger Lake, with initial
support implemented in Mesa (for Iris and Anv, our OpenGL and Vulkan
drivers), as well as in NEO (for OpenCL and Level0).

The new Xe driver leverages a lot from i915.

As for display, the intent is to share the display code with the i915
driver so that there is maximum reuse there. But it is not added
in this patch.

This initial work is a collaboration of many people and unfortunately
the big squashed patch won't fully honor the proper credits. But let's
get some git quick stats so we can at least try to preserve some of the
credits:
