And submit already has a fence assigned and is added to the submit_list. Any problems from here on out are asynchronous (ie. hangcheck/recovery). Signed-off-by: Rob Clark <robdclark@gmail.com>

For now there is just a single fence-context, but eventually we'll also have one per-CRTC to enable fully explicit fencing. Signed-off-by: Rob Clark <robdclark@gmail.com>

drm/msm/gpu: simplify tracking in-flight bo's 2016-05-08T14:16:03+00:00 Rob Clark robdclark@gmail.com 2016-03-16T20:07:38+00:00 7d12a279d421255792f2092f68262a79e3311dc2 Since we already track the array of bo's in the submit object, just unconditionally take and drop ref's per submit (rather than only taking ref's if bo is not already active). This simplifies later patches. Signed-off-by: Rob Clark <robdclark@gmail.com>

If the gpu hangs, retire up to an including the offending submit, and then re-submit the remainder. This way, for concurrently running piglit tests (for example), one failing test doesn't cause unrelated tests to fail simply because it's submit was queued up after one that triggered a hang.
