      drm/i915: Stop skipping the final clflush back to system pages · 2b3c8317
      Chris Wilson authored
      When we release the shmem backing storage, we make sure that the pages
      are coherent with the cpu cache. However, our clflush routine was
      skipping the flush as the object had no pages at release time. Fix this by
      explicitly flushing the sg_table we are decoupling.
      
      Fixes: 03ac84f1 ("drm/i915: Pass around sg_table to get_pages/put_pages backend")

      drm/i915: Only wait upon the execution timeline when unlocked · 9caa34aa
      Chris Wilson authored
      In order to walk the list of all timelines, we currently require the
      struct_mutex. We are sometimes called prior to the struct_mutex being
      taken by the caller (i.e !I915_WAIT_LOCKED) in which case we can only
      trust the global execution timelines (as these are owned by the device).
      This means in the unlocked phase we can only wait upon the currently
      executing requests and not all queued.

      drm/i915: Split out i915_vma.c · b42fe9ca
      Joonas Lahtinen authored
      As a side product, had to split two other files;
      - i915_gem_fence_reg.h
      - i915_gem_object.h (only parts that needed immediate untanglement)
      
      I tried to move code in as big chunks as possible, to make review
      easier. i915_vma_compare was moved to a header temporarily.
      
      v2:
      - Use i915_gem_fence_reg.{c,h}
      
      v3:
      - Rebased
      
      v4:
      - Fix building when DEBUG_GEM is enabled by reordering a bit.
