[Intel-gfx] [PATCH 0/4] Enable FBC on SKL

[Paulo Zanoni]

Hi

Here's a patch series to workaround the current SKL FBC problems, then try to
enable it by default.

Between patch 2/4 and the DDX patch, we only need one of them for things to
work. We'll also be fine if we merge both, but we need at least one.

No IGT changes are needed due to the automatic workaround disable during
dirtyfb/sw_finish.

Thanks,
Paulo

  drm/i915/fbc: update busy_bits even for GTT and flip flushes
  drm/i915/fbc: sanitize i915.enable_fbc during FBC init
  drm/i915: opt-out CPU and WC mmaps from FBC
  drm/i915/fbc: enable FBC on SKL too
