drm/amd/display: reprogram VM config when system resume

2019-10-07T16:58:56+00:00

[ Upstream commit e5382701c3520b3ed66169a6e4aa6ce5df8c56e0 ]

[Why]
The vm config will be clear to 0 when system enter S4. It will
cause hubbub didn't know how to fetch data when system resume.
The flip always pending because earliest_inuse_address and
request_address are different.

[How]
Reprogram VM config when system resume

drm/amd/display: fix issue where 252-255 values are clipped

2019-10-07T16:58:53+00:00

[ Upstream commit 1cbcfc975164f397b449efb17f59d81a703090db ]

[Why]
When endpoint is at the boundary of a region, such as at 2^0=1
we find that the last segment has a sharp slope and some points
are clipped at the top.

[How]
If end point is 1, which is exactly at the 2^0 region boundary, we
need to program an additional region beyond this point.

drm/amd/display: add monitor patch to add T7 delay

2019-10-07T16:58:31+00:00

[ Upstream commit 88eac241a1fc500ce5274a09ddc4bd5fc2b5adb6 ]

[Why]
Specifically to one panel,
TCON is able to accept active video signal quickly, but
the Source Driver requires 2-3 frames of extra time.

It is a Panel issue since TCON needs to take care of
all Sink requirements including Source Driver. But in
this case it does not.

Customer is asking to add fixed T7 delay as panel
workaround.

[How]
Add monitor specific patch to add T7 delay

drm/amd/display: readd -msse2 to prevent Clang from emitting libcalls to undefined SW FP routines

2019-10-01T07:01:36+00:00

[ Upstream commit 0f0727d971f6fdf8f1077180d495ddb9928f0c8b ]

arch/x86/Makefile disables SSE and SSE2 for the whole kernel.  The
AMDGPU drivers modified in this patch re-enable SSE but not SSE2.  Turn
on SSE2 to support emitting double precision floating point instructions
rather than calls to non-existent (usually available from gcc_s or
compiler_rt) floating point helper routines for Clang.

This was originally landed in:
commit 10117450735c ("drm/amd/display: add -msse2 to prevent Clang from emitting libcalls to undefined SW FP routines")
but reverted in:
commit 193392ed9f69 ("Revert "drm/amd/display: add -msse2 to prevent Clang from emitting libcalls to undefined SW FP routines"")
due to bugreports from GCC builds. Add guards to only do so for Clang.

drm/amd/display: Increase size of audios array

2019-08-16T08:11:02+00:00

[ Upstream commit 7352193a33dfc9b69ba3bf6a8caea925b96243b1 ]

[Why]
The audios array defined in "struct resource_pool" is only 6 (MAX_PIPES)
but the max number of audio devices (num_audio) is 7. In some projects,
it will run out of audios array.

[How]
Incraese the audios array size to 7.

drm/amd/display: Only enable audio if speaker allocation exists

2019-08-16T08:11:02+00:00

[ Upstream commit 6ac25e6d5b2fbf251e9fa2f4131d42c815b43867 ]

[Why]

In dm_helpers_parse_edid_caps, there is a corner case where no speakers
can be allocated even though the audio mode count is greater than 0.
Enabling audio when no speaker allocations exists can cause issues in
the video stream.

[How]

Add a check to not enable audio unless one or more speaker allocations
exist (since doing this can cause issues in the video stream).

drm/amd/display: Fix dc_create failure handling and 666 color depths

2019-08-16T08:11:01+00:00

[ Upstream commit 0905f32977268149f06e3ce6ea4bd6d374dd891f ]

[Why]
It is possible (but very unlikely) that constructing dc fails
before current_state is created.

We support 666 color depth in some scenarios, but this
isn't handled in get_norm_pix_clk. It uses exactly the
same pixel clock as the 888 case.

[How]
Check for non null current_state before destructing.

Add case for 666 color depth to get_norm_pix_clk to
avoid assertion.

drm/amd/display: put back front end initialization sequence

[ Upstream commit feb7eb522e0a7a22c1e60d386bd3c3bfa1d5e4f7 ]

[Why]
Seamless boot optimization removed proper front end power off sequence.
In driver disable enable case, this causes driver to power gate hubp
and dpp while there is still memory fetching going on, this can cause
invalid memory requests to be generated which will hang data fabric.

[How]
Put back proper front end power off sequence
