Rodrigo Vivi 1d73c2a8f2 drm/i915: Minimize the huge amount of unecessary fbc sw cache clean. ... The sw cache clean on BDW is a tempoorary workaround because we cannot set cache clean on blt ring with risk of hungs. So we are doing the cache clean on sw. However we are doing much more than needed. Not only when using blt ring. So, with this extra w/a we minimize the ammount of cache cleans and call it only on same cases that it was being called on gen7. The traditional FBC Cache clean happens over LRI on BLT ring when there is a frontbuffer touch happening. frontbuffer tracking set fbc_dirty variable to let BLT flush that it must clean FBC cache. fbc.need_sw_cache_clean works in the opposite information direction of ring->fbc_dirty telling software on frontbuffer tracking to perform the cache clean on sw side. v2: Clean it a little bit and fully check for Broadwell instead of gen8. v3: Rebase after frontbuffer organization. v4: Wiggle confused me. So fixing v3!
