drm/nouveau/fault: add explicit control over fault buffer interrupts
The GPU will continually fire interrupts while a fault buffer GET != PUT,
and to stop the spurious interrupts while the handler does its thing, we
were disabling the fault buffer temporarily.
This is not actually a great idea to begin with, and made worse by Volta
resetting GET/PUT when it's reactivated. So, let's not do that.

drm: Add a new plane property to send damage during plane update
FB_DAMAGE_CLIPS is an optional plane property to mark damaged regions
on the plane in framebuffer coordinates of the framebuffer attached to
the plane.
The layout of blob data is simply an array of "struct drm_mode_rect".
Unlike plane src coordinates, damage clips are not in 16.16 fixed point.
As plane src in framebuffer cannot be negative so are damage clips. In
damage clip, x1/y1 are inclusive and x2/y2 are exclusive.
This patch also exports the kernel internal drm_rect to userspace as
drm_mode_rect. This is because "struct drm_clip_rect" is not sufficient
to represent damage for current plane size.
Driver which are interested in enabling FB_DAMAGE_CLIPS property for a
plane should enable this property using drm_plane_enable_damage_clips.
v2:
- Input validation on damage clips against framebuffer size.
- Doc update, other minor changes.

Update the ipu-v3 mem2mem image-convert code, with some fixes for race
conditions, alignment issues, and visual artifacts due to tile alignment
and scaling factor issues when scaling images larger than hardware
limitations in multiple tiles. This will allow the V4L2 mem2mem scaler
driver to write output images larger than 1024x1024 pixels.
Also switch drm/imx source files to SPDX license identifiers, constify
struct clk_ops in imx-tve, and add a timeout warning to the busy wait in

drm/i915/icl: fix transcoder state readout

Use a bitmask for iterating and logging transcoders, because the allowed

drm/i915: Allocate a common scratch page
Currently we allocate a scratch page for each engine, but since we only
ever write into it for post-sync operations, it is not exposed to
userspace nor do we care for coherency. As we then do not care about its
contents, we can use one page for all, reducing our allocations and
avoid complications by not assuming per-engine isolation.
For later use, it simplifies engine initialisation (by removing the
allocation that required struct_mutex!) and means that we can always rely
on there being a scratch page.

drm/i915: Introduce per-engine workarounds
We stopped re-applying the GT workarounds after engine reset since commit
59b449d5c82a ("drm/i915: Split out functions for different kinds of
workarounds").
Issue with this is that some of the GT workarounds live in the MMIO space
which gets lost during engine resets. So far the registers in 0x2xxx and
0xbxxx address range have been identified to be affected.
This losing of applied workarounds has obvious negative effects and can
even lead to hard system hangs (see the linked Bugzilla).
Rather than just restoring this re-application, because we have also
observed that it is not safe to just re-write all GT workarounds after
engine resets (GPU might be live and weird hardware states can happen),
we introduce a new class of per-engine workarounds and move only the
affected GT workarounds over.
Using the framework introduced in the previous patch, we therefore after
engine reset, re-apply only the workarounds living in the affected MMIO
address ranges.
