full_update_required is too strict at update_planes_and_stream_state,
causing a performance regression due to too many updates being full.

dc_check_update_surfaces_for_stream should not have access to entire

to run independently of one another, without risk of changing state.

Separating the panic allocation from framebuffer allocation in commit
729c5f7ffa ("drm/{i915,xe}/panic: move framebuffer allocation where it

The fix is two-fold. First, free the panic structure in
intel_user_framebuffer_destroy() in the general case. Second, move the
panic allocation later to intel_framebuffer_init() to not leak the panic
structure in error paths (if any, now or later) between
intel_framebuffer_alloc() and intel_framebuffer_init().

v2: Rebase

When mapping the pages of a BO, either a heap type at page fault time or
else a non-heap BO at object creation time, if the ARM page table mapping
function fails, we unmap what had been mapped so far and bail out.

3d7c626716 drm/panfrost: Check sgt to know whether pages are already mapped
In the MMU's page fault ISR for a heap object, determine whether the
faulting address belongs to a 2MiB block that was already mapped by
checking its corresponding sgt in the Panfrost BO.

This is done in preparation for a future commit in which the MMU mapping
helper might fail, but the page array is left populated, so this cannot
be used as a check for an early bail-out.

616c5b6fe3 drm/panfrost: Handle job HW submit errors
Avoid waiting for the DRM scheduler job timedout handler, and instead, let
the DRM scheduler core signal the error fence immediately when HW job
submission fails.

That means we must also decrement the runtime-PM refcnt for the device,
because the job will never be enqueued or inflight.

5c0c825ae4 drm/panfrost: Replace DRM driver allocation method with newer one
Drop the deprecated DRM driver allocation method in favour of
devm_drm_dev_alloc(). Overall just make it the same as in Panthor.
Also discard now superfluous generic and platform device pointers inside
the main panfrost device structure.

Some ancient checkpatch issues unearthed as a result of these changes
were also fixed, like lines too long or double assignment in one line.

4bfaa85bb5 drm/rockchip: Declare framebuffer width/height bounds
The VOP2 has limitations on its input and output sizes. The clipped
display region must be at least 4px in each dimension for both
framebuffer source and plane destination, and the clipped source region
must be no greater than a per-version limit.

It is never valid for VOP2 to have a framebuffer which is less than four
pixels in either dimension, so declare that as our min width/height,
enforced by AddFB failing if the user tries. It can theoretically be
valid to have a single large framebuffer of which only certain clipped
regions are shown, but this is a very uncommon case. Declaring to
userspace that the framebuffer's maximum width and height is the maximum
source clip helps it make better decisions as to which mode to use,
instead of trying unsupported sizes and having to fall back.

A plane check failing is a normal and expected condition, as userspace
isn't aware of the specific constraints and will try any and every
combination until one succeeds. Push this down to a debug message, so
users can see it if they want to, but make sure we don't spam the log
during normal operation.
