[Intel-gfx] [PATCH 03/20] drm/i915/fbc: Nuke lots of crap from intel_fbc_state_cache
Ville Syrjala
ville.syrjala at linux.intel.com
Wed Nov 24 11:36:35 UTC 2021
From: Ville Syrjälä <ville.syrjala at linux.intel.com>
There's no need to store all this stuff in intel_fbc_state_cache.
Just check it all against the plane/crtc states and store only
what we need. Probably more should get nuked still, but this
is a start.
So what we'll do is:
- each plane will check its own state and update its local
no_fbc_reason
- the per-plane no_fbc_reason (if any) then gets propagated
to the cache->no_fbc_reason while doing the actual update
- fbc->no_fbc_reason gets updated in the end with either
the value from the cache or directly from frontbuffer
tracking
It's still a bit messy, but should hopefuly get cleaned up
more in the future. At least now we can observe each plane's
reasons for rejecting FBC now more consistently, and we don't
have so mcuh redundant state store all over the place.
v2: store no_fbc_reason per-plane instead of per-pipe
