      dma-buf: Rename struct fence to dma_fence · f54d1867
      Chris Wilson authored
      I plan to usurp the short name of struct fence for a core kernel struct,
      and so I need to rename the specialised fence/timeline for DMA
      operations to make room.
      
      A consensus was reached in
      https://lists.freedesktop.org/archives/dri-devel/2016-July/113083.html
      
      
      that making clear this fence applies to DMA operations was a good thing.
      Since then the patch has grown a bit as usage increases, so hopefully it
      remains a good thing!
      
      (v2...: rebase, rerun spatch)
      v3: Compile on msm, spotted a manual fixup that I broke.
      v4: Try again for msm, sorry Daniel

      drm/vmwgfx: Replace the hw mutex with a hw spinlock · 496eb6fd
      Thomas Hellstrom authored
      
      
      Fixes a case where we call vmw_fifo_idle() from within a wait function with
      task state !TASK_RUNNING, which is illegal.
      
      In addition, make the locking fine-grained, so that it is performed once
      for every read- and write operation. This is of course more costly, but we
      don't perform much register access in the timing critical paths anyway. Instead
      we have the extra benefit of being sure that we don't forget the hw lock around
      register accesses. I think currently the kms code was quite buggy w r t this.
      
      This fixes Red Hat Bugzilla Bug 1180796

      drivers: gpu: Mark functions as static in vmwgfx_fence.c · 94844cf0

      Mark functions as static because they are not used outside the file
      drm/vmwgfx/vmwgfx_fence.c.
      
      This eliminates the following warnings in drm/vmwgfx/vmwgfx_fence.c:
      drivers/gpu/drm/vmwgfx/vmwgfx_fence.c:274:6: warning: no previous prototype for ‘vmw_fences_perform_actions’ [-Wmissing-prototypes]

      drm/ttm: ttm object security fixes for render nodes · 05efb1ab
      Thomas Hellstrom authored
      
      
      When a client looks up a ttm object, don't look it up through the device hash
      table, but rather from the file hash table. That makes sure that the client
      has indeed put a reference on the object, or in gem terms, has opened
      the object; either using prime or using the global "name".
      
      To avoid a performance loss, make sure the file hash table entries can be
      looked up from under an RCU lock, and as a consequence, replace the rwlock
      with a spinlock, since we never need to take it in read mode only anymore.
      
      Finally add a ttm object lookup function for the device hash table, that is
      intended to be used when we put a ref object on a base object or, in  gem terms,
      when we open the object.
