      drm/i915: Fix random aux transactions failures. · 14e01889
      Rodrigo Vivi 提交于
      Mainly aux communications on sink_crc
      were failing a lot randomly on recent platforms.
      The first solution was to try to use intel_dp_dpcd_read_wake, but then
      it was suggested to move retries to drm level.
      
      Since drm level was already taking care of retries and didn't want
      to through random retries on that level the second solution was to
      put the retries at aux_transfer layer what was nacked.
      
      So I realized we had so many retries in different places and
      started to organize that a bit. During this organization I noticed
      that we weren't handing at all the case were the message size was
      zeroed. And this was exactly the case that was affecting sink_crc.
      
      Also we weren't respect BSPec who says this size message = 0 or > 20
      are forbidden.
      
      It is a fact that we still have no clue why we are getting this
      forbidden value there. But anyway we need to handle that for now
      so we return -EBUSY and drm level takes care of the retries that
      are already in place.
      
      v2: Print debug messsage when this case is reached as suggested
          by Jani.
      v3: This patch is crucial to make PSR test cases reliably working
          on SKL. So split this patch from the aux re-org series and add
          a FIXME as a promisse to continue that effort besides reminding
          to remove the sleep when that is merged.
      v4: Use a bigger usleep range so kernel doesn't need to be interrupted
          on a exact time, as suggested by Paulo.
          But anyway we should discuss the better time
          ranges on the EBUSY handle re-org at drm level since this one here
          is temporary.
      v5: s/1000,1500/1000, 1500/ (by Paulo).
