Daniel Vetter d472fcc837 drm/i915: Disallow pin ioctl completely for kms drivers ... The problem here is that SNA pins batchbuffers to etch out a bit more performance. Iirc it started out as a w/a for i830M (which we've implemented in the kernel since a long time already). The problem is that the pin ioctl wasn't added in commit d23db88c3a Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Fri May 23 08:48:08 2014 +0200 drm/i915: Prevent negative relocation deltas from wrapping Fix this by simply disallowing pinning from userspace so that the kernel is in full control of batch placement again. Especially since distros are moving towards running X as non-root, so most users won't even be able to see any benefits. UMS support is dead now, but we need this minimal patch for backporting. Follow-up patch will remove the pin ioctl code completely. Note to backporters: You must have both commit b45305fce5 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Mon Dec 17 16:21:27 2012 +0100 drm/i915: Implement workaround for broken CS tlb on i830/845 which laned in 3.8 and commit c4d69da167 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Mon Sep 8 14:25:41 2014 +0100 drm/i915: Evict CS TLBs between batches which is also marked cc: stable. Otherwise this could introduce a regression by disabling the userspace w/a without the kernel w/a being fully functional on i830/45.
