      drm/radeon: add locking around atombios scratch space usage · 1c949842
      Dave Airlie authored
      While developing MST support I noticed I often got the wrong data
      back from a transaction, in a racy fashion. I noticed the scratch
      space wasn't locked against concurrent users.
      
      Based on a patch by Alex, but I've made it a bit more obvious when
      things are locked.

      drm/i915: Fix obj->map_and_fenceable across tiling changes · e9d784d5
      Chris Wilson authored
      As obj->map_and_fenceable computation has changed to only be set when
      the object is bound inside the global GTT (and is suitable aligned to a
      fence region) we need to accommodate those changes when the tiling is
      adjusted. The easiest solution is to unbind from the global GTT if we
      are currently fenceable, but will not be after the tiling change.
      
      The bug has been exposed by
      
      commit f8fcadba218fe6d23b2e353fea1cf0a4be4c9454

          drm/i915: Only mark as map-and-fenceable when bound into the GGTT
      
      which tried to fix an oversight from
      
      commit e6a84468
      Author: Chris Wilson <chris@chris-wilson.co.uk>
      Date:   Mon Aug 11 12:00:12 2014 +0200
      
          drm/i915: Force CPU relocations if not GTT mapped
      
      which changed the handling of obj->map_and_fenceable.
      
      Note that the alignment check is a vestige from our attempts to reduce
      the alignment requirements of tiled but unfenced buffers on
      gen2/3. Also, that was when unbinding from the GTT meant UC writes and
      clflushing, so we went to great pains to avoid such.
      
      That leaves the actual bug of setting map_and_fenceable to true if we're
      not bound to ggtt, which violates the change introduced in the above
      patch. Unbinding in that case really looks like the simplest and safest
      option, we have to do it anyway.

       "Running the ftracetests on a machine that had the debugfs file system
        mounted in two locations caused the ftracetests to fail.  This is
        because the ftracetests script does a grep of the /proc/mounts file to
        find where the debugfs file system is mounted.  If it is mounted
        twice, then the grep returns two lines instead of just one.  This
        causes the ftracetests to get confused and fail.
