719423f670 drm/amdgpu: wait for all rings to drain before runtime suspending
Add a safety check to runtime suspend to make sure all outstanding
fences have signaled before we suspend.  Doesn't fix any known issue.

We already do this via the fence driver suspend function, but we
just force completion rather than bailing.  This bails on runtime
suspend so we can try again later once the fences are signaled to
avoid missing any outstanding work.

5a7489a7e1 drm/amdgpu: fix KIQ ring test fail in TDR of SRIOV
issues:
MEC is ruined by the amdkfd_pre_reset after VF FLR done

fix:
amdkfd_pre_reset() would ruin MEC after hypervisor finished the VF FLR,
the correct sequence is do amdkfd_pre_reset before VF FLR but there is
a limitation to block this sequence:
if we do pre_reset() before VF FLR, it would go KIQ way to do register
access and stuck there, because KIQ probably won't work by that time
(e.g. you already made GFX hang)

so the best way right now is to simply remove it.

6426745427 drm/amd/display: fix missing cursor on some rotated SLS displays
[Why]
Cursor disappears for some SLS displays that are rotated 180
and 270 degrees.  This occurs when there is no pipe split being
done ( ex. 3 or more displays ).  The cursor calculations assume
pipe splitting is done so when it calculates the new cursor
position in hwss.set_cursor_position(), it is out-of-bounds so
it disables the cursor in hubp.set_cursor_position().

[How]
In non pipe split cases, calculate cursor using viewport size
( width or height ) instead of viewport size * 2 ( the two
because pipe splitting divides the rectangle into two ).

89d07b662f drm/amd/display: fix 270 degree rotation for mixed-SLS mode
[Why]
When we rotate 270 in mixed SLS mode, the recouts occupy the
right side of the display.  So all the recout_skip_v values
are relative to the left side of the display.  This causes
adjust_vp_and_init_for_seamless_clip() to incorrectly increase
the data->viewport.height for that recout.  The rotation looks
like the bottom half is duplicated twice.

[How]
recout.x values are being adjusted based on
stream->timing.h_border_left.  Instead of using h_border_left,
use dst.x to represent the border.  Shift dst.x by the amount of
stream->timing.h_border_left and set
stream->timing.h_border_left to 0.  Do all the calculations
and then revert stream->timing.h_border_left and
stream->dst.x back to their original values.
When calculating pipe_ctx->plane_res.scl_data.h_active,
make sure to use the original stream->timing.h_border_left
value.

1380c1bf5b drm/amd/display: Remove reliance on pipe indexing
[Why]
In certain instances, there was a reliance on pipe indexing being accurate. However, this
assumption fails with harvesting of pipes 1 or 2, which can occur in production B6 parts.
HW hang would occur as a result.

[How]
Use hubp index for mpcc, and do mpc_init for all theoretical pipes (including disabled ones).

8c7aea404d drm/amd/display: Perform DMUB hw_init on resume
[Why]
The DMUB is put into reset on suspend and is not running on resume,
disabling PSR/ABM features.

[How]
Move the allocation of the framebuffer to sw_init.

Do DMUB hardware init and framebuffer filling only from hw_init.

On resume the contents of the framebuffer will be invalid so those
should be cleared.
