[git pull] drm fixes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

Hi Linus,

A bunch of fixes:

vmware memory corruption, ttm spinlock balance,
cirrus/mgag200, work in the presence of efifb
and finally Alex and Jerome managed to track down a magic set of bits that 
on certain rv740 and evergreen cards allow the correct use of the 
complete set of render backends, this makes the cards operate correctly in 
a number of scenarios we had issues in before, it also manages to boost 
speed on benchmarks my large amounts on these specific gpus.
