drm/msm: drop return from gpu->submit() 2016-05-08T14:22:18+00:00 Rob Clark robdclark@gmail.com 2016-05-03T13:46:49+00:00 1193c3bcb581807d58dd7df90528ec744af387a9 At this point, there is nothing left to fail. 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>

drm/msm: introduce msm_fence_context 2016-05-08T14:19:51+00:00 Rob Clark robdclark@gmail.com 2016-03-15T21:22:13+00:00 ca762a8ae7f453978a4769af9dcd3cb08e45b932 Better encapsulate the per-timeline stuff into fence-context. 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: restart queued submits after hang 2015-06-11T17:11:06+00:00 Rob Clark robdclark@gmail.com 2015-06-07T17:46:04+00:00 1a370be9ac51129e40b0ed7fa71d2b2b92bc47e5 Track the list of in-flight submits. 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.

drm/msm: adreno a306 support 2015-06-11T17:11:01+00:00 Rob Clark robdclark@gmail.com 2015-05-06T17:14:30+00:00 de558cd2ae2e9999d0b6328c22c398ff85b6327c As found in apq8016 (used in DragonBoard 410c) and msm8916. Note that numerically a306 is actually 307 (since a305c already claimed 306). Nice and confusing. Signed-off-by: Rob Clark <robdclark@gmail.com>

drm/msm: clarify downstream bus scaling 2015-06-11T17:11:01+00:00 Rob Clark robdclark@gmail.com 2015-06-04T14:26:37+00:00 6490ad47404539b479ca33f96793c4624bef2924 A few spots in the driver have support for downstream android CONFIG_MSM_BUS_SCALING. This is mainly to simplify backporting the driver for various devices which do not have sufficient upstream kernel support. But the intentionally dead code seems to cause some confusion. Rename the #define to make this more clear. Signed-off-by: Rob Clark <robdclark@gmail.com>
