Although "multi-tile" and "multiple GTs per tile" are mutually-exclusive
characteristics on all of our platforms today, this may not always be
true. Assign GT IDs according to xe->info.max_gt_per_tile in a way that
should work even if future platforms have different configurations.
This patch should not change the behavior of current platforms; it only
future-proofs for potential future designs.
v2:
- Re-calculate gt_count if tile count gets reduced by MTCFG. (PVC CI)

Add a simple kunit test to ensure each platform's GT per tile count is
non-zero and does not exceed the global XE_MAX_GT_PER_TILE definition.
We need to move 'struct xe_subplatform_desc' from the .c file to the
types header to ensure it is accessible from the kunit test.
v2:
- Rebase on latest xe_pci test rework from Michal and convert to
a parameterized test that runs on each PCI ID supported by the
driver.

Today all of our platforms fall into one of three cases:
* Single tile platforms with a single (primary) GT
* Single tile platforms with two GTs (primary + media)
* Two-tile platforms with a single GT (primary) in each
Our numbering of GTs has been a bit inconsistent between platforms
(e.g., GT1 is the media GT on some platforms, but the second tile's
primary GT on others). In the future we'll likely have platforms that
are both multi-tile and multi-GT, which will make the situation more
confusing. We could also wind up with more than just two types of GTs
at some point in the future.
Going forward we should standardize the way we assign uapi GT IDs to
internal GT structures. Let's declare that for userspace GT ID n,
GT[n]'s tile = n / (max gt per tile)
GT[n]'s slot within tile = n % (max gt per tile)
We don't want the GT numbering to change for any of our current
platforms since the current IDs are part of our ABI contract with
userspace so this means we should track the 'max gt per tile' value on a
per-platform basis rather than just using a single value across the
driver. Encode this into device descriptors in xe_pci.c and use the
per-platform number for various checks in the code. Constant
XE_MAX_GT_PER_TILE will remain just as the maximum across all platforms
for easy of sizing array allocations.

xe_step_name() is used by xe_assert(), so adding assertions to functions
like xe_device_get_gt() will result in

If we fail to allocate a workqueue we will leak kzalloc'ed group
object since it was designed to be kfree'ed in the drmm cleanup
action, but we didn't have a chance to register this action yet.
To avoid this leak allocate a group object using drmm_kzalloc()
and start using predefined drmm action to release the workqueue.

Prefer the register read specific wait function over i915 wait_for_us().
The existing condition is quite complicated. Simplify by checking for
requesters first, and determine timeout based on that. Refresh
requesters in case of timeouts, should one have popped up during the
wait. The downside is that this does not cut the wait short if
requesters show up *during* the wait, but we're talking about 1 ms so
shouldn't be an issue.

Drop the unused MIPI_DSI_MODE_VSYNC_FLUSH flag. Whether or not a display
FIFO flush on vsync is required to avoid sending garbage to the panel is

Always flush the display FIFO on vsync pulse, even if not explicitly
requested by the panel via MIPI_DSI_MODE_VSYNC_FLUSH mode_flag.
The display FIFO should be empty at vsync. Flushing it at vsync pulses
helps to remove garbage that may have entered the FIFO during startup
(if synchronisation between upstream display controller and Samsung DSIM
is lacking) and that may persist in form of last frame's leftovers on
subsequent frames. Flushing the display FIFO if it is already empty
should have no effect.
This will allow to remove the MIPI_DSI_MODE_VSYNC_FLUSH flag, which is
only used by the Samsung DSIM bridge driver. Arguably this flag doesn't
belong in the panel configuration at all: flushing the display FIFO on
vsync is a workaround for issues with the integration between display
controller and DSI bridge, not a property of the DSI link between bridge
and panel. No panel actually has a requirement to receive garbage or old
frame content after vsync.
I wonder if host controller FIFO resets are mentioned by the MIPI DSI
specification at all. This patch is based on the assumption that the
MIPI_DSI_MODE_VSYNC_FLUSH flag only exists because the DSIM_MFLUSH_VS
bit happens to be located in the same register as the bits controlling
the DSI mode.

MEI GSC interrupt comes from i915. It has top half and bottom half.
Top half is called from i915 interrupt handler. It should be in
irq disabled context.
With RT kernel, by default i915 IRQ handler is in threaded IRQ. MEI GSC
top half might be in threaded IRQ context. generic_handle_irq_safe API
could be called from either IRQ or process context, it disables local
IRQ then calls MEI GSC interrupt top half.
This change fixes A380/A770 GPU boot hang issue with RT kernel.

[WHY]
On DCN314, using full screen application with enabled scaling like 150%,
175%, with overlay cursor, causes a second cursor to appear when changing
planes. Dpp cache is used to track the HW cursor enable. Since power gate
is disabled for hubp & dpp in DCN314, dpp_reset() zero'ed the dpp struct,
while the dpp hardware was not power gated.
So, when plane is changed in a full screen app, and the overlay cursor is
enabled, the cache is cleared, so the cache does not represent the actual
cursor state.
[HOW]
Added conditionals for dpp & hubp reset and their pg_control functions
only if according power_gate flags are enabled.

patch dd64956685fa ("drm/amdgpu: Remove duplicated "context still

Instead of testing import_attach for imported GEM buffers, invoke
drm_gem_is_imported() to do the test.
