X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6bda10d152735c22baf1dcd92937420b4b0a359a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Completely disable fence pipelining. I'm still seeing tiling corruption of PutImage and CopyArea (I think) under mutter on pnv, so obviously the pipelining logic is deeply flawed.
