[PATCH] drm/i915/gen9: Disable FBC on planes with a misaligned Y-offset

[PATCH] drm/i915/gen9: Disable FBC on planes with a misaligned Y-offset

[Imre Deak]

Enabling FBC on a plane having a Y-offset that isn't dividable by 4 may
cause pipe FIFO underruns and flickers, so disable FBC on such a config.

I tried to the followings to work around the issue:
- enable each HW work around in ILK_DPFC_CHICKEN
- disable each compression algorithm in ILK_DPFC_CONTROL
- disable low-power watermarks
None of the above got rid of the problem. I haven't found this issue in
the Bspec/WA database either.

Besides the igt testcase below (yet to be merged) an easy way to
reproduce the issue is to enable a plane with FBC and a plane Y-offset
not aligned to 4 and then just enable/disable FBC in a loop, keeping the
plane enabled.

I could trigger the problem on BXT/GLK/SKL, so assume for now that it's
only present on GEN9.

IS_GEN9()?

I do wonder about gen10+ however. GLK display pipes/planes did come
from CNL after all so it seems at least possible tht CNL suffers from
the same issue.

The patch seems sensible either way so

Ok, will fix those.

Hm, right. I thought to enable the WA on CNL in case the same happens in
CI once the igt test is merged. It happens with the testcase somewhat
sporadically though but easy to repro with the FBC on/off method, so
I'll give it a go tomorrow on CNL as well.

I wonder if adding a better testcase doing only FBC on/off would make
sense (without the current delay during FBC enabling).

[PATCH v2] drm/i915/gen9, gen10: Disable FBC on planes with a misaligned Y-offset

[Imre Deak]

Enabling FBC on a plane having a Y-offset that isn't divisible by 4 may
cause pipe FIFO underruns and flickers, so disable FBC on such a config.

I tried the followings to work around the issue:
- enable each HW work around in ILK_DPFC_CHICKEN
- disable each compression algorithm in ILK_DPFC_CONTROL
- disable low-power watermarks
None of the above got rid of the problem. I haven't found this issue in
the Bspec/WA database either.

Besides the igt testcase below (yet to be merged) an easy way to
reproduce the issue is to enable a plane with FBC and a plane Y-offset
not aligned to 4 and then just enable/disable FBC in a loop, keeping the
plane enabled.

I could trigger the problem on BXT/GLK/SKL/CNL, so assume for now that it's
only present on GEN9 and GEN10.

v2: (Ville)
- Run the test/apply the WA on CNL as well.
- Use IS_GEN() instead of INTEL_GEN().
- Fix spelling.
