93b6bd307a drm/amd/display: change zstate allow msg condition
[Why]
PMFW message which previously thought to only control Z9 controls both
Z9 and Z10. Also HW design team requested that Z9 must only be supported
on eDP due to content protection interop.

[How]
Change zstate support condition to match updated policy

Buffer can be used as extended memory for P State change latency hiding.
The maximum number of lines is increased to 32 lines. Finally,
LB_MEMORY_CONFIG_1 (LB memory piece 1) and LB_MEMORY _CONFIG_2 (LB

d7940911fc drm/amd/display: Fix max vstartup calculation for modes with borders
[Why]
Vertical and horizontal borders in timings are treated as increasing the
active area - vblank and hblank actually shrink.

Our input into DML does not include these borders so it incorrectly
assumes it has more time than available for vstartup and tmdl
calculations for some modes with borders.

An example of such a timing would be 640x480@72Hz:

h_total: 832
h_border_left: 8
h_addressable: 640
h_border_right: 8
h_front_porch: 16
h_sync_width: 40
v_total: 520
v_border_top: 8
v_addressable: 480
v_border_bottom: 8
v_front_porch: 1
v_sync_width: 3
pix_clk_100hz: 315000

[How]
Include borders as part of destination vactive/hactive.

This change DCN20+ so it has wide impact, but the destination vactive
and hactive are only really used for vstartup calculation anyway.

Most modes do not have vertical or horizontal borders.

scaled up in an irregular way. Reverting the commit or applying this

0abb33bfca drm/i915/gtt: drop the page table optimisation
We skip filling out the pt with scratch entries if the va range covers
the entire pt, since we later have to fill it with the PTEs for the
object pages anyway. However this might leave open a small window where
the PTEs don't point to anything valid for the HW to consume.

When for example using 2M GTT pages this fill_px() showed up as being
quite significant in perf measurements, and ends up being completely
wasted since we ignore the pt and just use the pde directly.

Anyway, currently we have our PTE construction split between alloc and
insert, which is probably slightly iffy nowadays, since the alloc
doesn't actually allocate anything anymore, instead it just sets up the
page directories and points the PTEs at the scratch page. Later when we
do the insert step we re-program the PTEs again. Better might be to
squash the alloc and insert into a single step, then bringing back this
optimisation(along with some others) should be possible.

2feeb52859 drm/i915/gt: Fix -EDEADLK handling regression
The conversion to ww mutexes failed to address the fence code which
already returns -EDEADLK when we run out of fences. Ww mutexes on
the other hand treat -EDEADLK as an internal errno value indicating
a need to restart the operation due to a deadlock. So now when the
fence code returns -EDEADLK the higher level code erroneously
restarts everything instead of returning the error to userspace
as is expected.

To remedy this let's switch the fence code to use a different errno
value for this. -ENOBUFS seems like a semi-reasonable unique choice.
Apart from igt the only user of this I could find is sna, and even
there all we do is dump the current fence registers from debugfs
into the X server log. So no user visible functionality is affected.
If we really cared about preserving this we could of course convert
back to -EDEADLK higher up, but doesn't seem like that's worth
the hassle here.

Not quite sure which commit specifically broke this, but I'll
just attribute it to the general gem ww mutex work.

c010efb7f0 drm/amdgpu/display - only update eDP's backlight level when necessary
[Why]
The original logic is to update eDP's backlight level
on every amdgpu dm atomic commit, which causes excessive
DMUB write. As a result, when playing game or moving window
around, DMUB timeout and system lagging are observed.

[How]
We only need to update eDP's backlight level when current level
doesn't match requested level.

e9cfe00ba8 drm/amd/display: Fix updating infoframe for DCN3.1 eDP
[Why]
We're only treating TMDS as a valid target for infoframe updates which
results in PSR being unable to transition from state 4 to state 5.

[How]
Also allow infoframe updates for DCN3.1 - following how we handle
this path for earlier ASIC as well.

43a44c5322 drm/amdgpu: Return error if no RAS
In amdgpu_ras_query_error_count() return an error
if the device doesn't support RAS. This prevents
that function from having to always set the values
of the integer pointers (if set), and thus
prevents function side effects--always to have to
set values of integers if integer pointers set,
regardless of whether RAS is supported or
not--with this change this side effect is
mitigated.

Also, if no pointers are set, don't count, since
we've no way of reporting the counts.

Also, give this function a kernel-doc.

ffe000217c dma-buf/sync_file: Don't leak fences on merge failure
Each add_fence() call does a dma_fence_get() on the relevant fence.  In
the error path, we weren't calling dma_fence_put() so all those fences
got leaked.  Also, in the krealloc_array failure case, we weren't
freeing the fences array.  Instead, ensure that i and fences are always
zero-initialized and dma_fence_put() all the fences and kfree(fences) on
every error path.
