[PATCH 0/6] drm/msm: GPU debugging enhancements

[Rob Clark <robdclark-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

Something that I've been using locally for a while, and found quite
helpful for debugging gallium driver issues:

 1) Better messages about what process triggered a crash, which is
    in particular particularly useful for piglit
 2) Mechanism to dump just submits which triggered GPU hangs.

Eventually I want to extend #2 to also dump submits that trigger
faults, but this is going to require spiffing out IOMMU framework
somewhat.. in particular we can't dump from IRQ context, so a
workqueue is needed, but we want to keep the IOMMU stalled until
after we dump the submit.  Maybe we'll get something useable out
of the currently discussed SVM patches.

Rob Clark (6):
  drm/msm: show task cmdline in gpu recovery messages
  drm/msm: add special _get_vaddr_active() for cmdstream dumps
  drm/msm: split rd debugfs file
  drm/msm/rd: allow adding addition msg to top of dump
  drm/msm: preserve IOVAs in submit's bo table
  drm/msm: dump submits which triggered gpu hang
