[PATCH 0/8] Improvements for IB handling V9

[Alex Deucher <alexander.deucher@amd.com>]

This set contains a number of bug fixes and cleanups for
IB handling that I worked on over the holidays.  Many of
the original patches have landed now.  These are the
remaining patches.

Patch 1:
Rework the backup and reemit code for per ring reset so that
we can safely reemit repeatedly.  This removes the current
single reemit limit currently in place.  V9 moves this to the start
of the series as its dependencies have been reviewed and
applied.

Patches 2-4:
Removes the direct submit path for IBs and requires
that all IB submissions use a job structure.  This
greatly simplifies the IB submission code. V2 uses
GFP_ATOMIC when in reset.  V3 sqaushes all of the
IP changes into one patch.  Not sure there is much
value breaking this out per IP. V4 uses the pool type
to determine the alloc flags. No changes in V8.
V9 fixes some typos in the gfx9 RAS IB handling.

Patches 5-8:
Improvements for adapter resets.  Properly add the bad job
back to the pending list so we can stop calling
drm_sched_stop/start().  Return the proper error number
in the CS IOCTL when the context is guilty.  Now that that
is handled properly we can call drm_sched_increase_karma()
for ring resets as well.  Properly set the error on the the
timedout fence for adapter resets.  These changes also resulted
in a small clean up the the VCN reset helpler.  No changes in
V9.

Alex Deucher (8):
  drm/amdgpu: rework ring reset backup and reemit v9
  drm/amdgpu/job: use GFP_ATOMIC while in gpu reset
  drm/amdgpu: switch all IPs to using job for IBs
  drm/amdgpu: require a job to schedule an IB
  drm/amdgpu: plumb timedout fence through to force completion
  drm/amdgpu: simplify VCN reset helper
  drm/amdgpu/cs: return -ETIME for guilty contexts
  drm/amdgpu: Call drm_sched_increase_karma() for ring resets
