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

2018-02-28 Thread 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_CON
