From: Ville Syrjälä <[email protected]>
Avoid all the FBC frontbuffer vs. atomic commit raciness
by not doing any FBC nukes while a flip is pending. Allows
us to remove the last locks from the i9xx plane code.
I also want to explore the idea of always generating DSB
batches for pipe commits and just excuting them on the
CPU if no DSB hardware is available. Locked register writes
(and any register reads, of which there are still a few)
prevent me from doing that.
Ville Syrjälä (7):
drm/i915/fbc: Eliminate possible_framebuffer_bits
drm/i915/fbc: Streamline frontbuffer busy bits handling
drm/i915/fbc: Skip nuke when flip is pending
drm/i915: Remove remaining locks from i9xx plane udpates
drm/i915/fbc: Remove intel_fbc_global_disable()
drm/i915/fbc: Introduce intel_fbc_sanitize()
drm/i915/fbc: Call intel_fbc_activate() directly from frontbuffer
