      drm/nouveau/kms/nve4-nv108: Limit cursors to 128x128 · d3999c1f
      Lyude Paul 提交于
      While Kepler does technically support 256x256 cursors, it turns out that
      Kepler actually has some additional requirements for scanout surfaces that
      we're not enforcing correctly, which aren't present on Maxwell and later.
      Cursor surfaces must always use small pages (4K), and overlay surfaces must
      always use large pages (128K).
      
      Fixing this correctly though will take a bit more work: as we'll need to
      add some code in prepare_fb() to move cursor FBs in large pages to small
      pages, and vice-versa for overlay FBs. So until we have the time to do
      that, just limit cursor surfaces to 128x128 - a size small enough to always
      default to small pages.
      
      This means small ovlys are still broken on Kepler, but it is extremely
      unlikely anyone cares about those anyway :).

      drm/i915: Fix the GT fence revocation runtime PM logic · 8840e3bd
      Imre Deak 提交于
      To optimize some task deferring it until runtime resume unless someone
      holds a runtime PM reference (because in this case the task can be done
      w/o the overhead of runtime resume), we have to use the runtime PM
      get-if-active logic: If the runtime PM usage count is 0 (and so
      get-if-in-use would return false) the runtime suspend handler is not
      necessarily called yet (it could be just pending), so the device is not
      necessarily powered down, and so the runtime resume handler is not
      guaranteed to be called.
      
      The fence revocation depends on the above deferral, so add a
      get-if-active helper and use it during fence revocation.
      
      v2:
      - Add code comment explaining the fence reg programming deferral logic
        to i915_vma_revoke_fence(). (Chris)
      - Add Cc: stable and Fixes: tags. (Chris)
      - Fix the function docbook comment.
