* gpu: nvgpu: Dump offending push buffer fragmentTerje Bergstrom2015-03-18
| | | | | | | | | | | | | | When outputting debug dump, print the contents of current push buffer segment. Also changes the debug dump to use pr_cont when applicable, and dumps state before recovering in case channel was not loaded to an engine.

* gpu: nvgpu: Support semaphore sync when aborting jobsLauri Peltonen2015-03-18
| | | | | | | | | | | | | | | | | | | | | | | | | When aborting jobs on channel error situations, we manually set the channel syncpoint's min == max in gk20a_disable_channel_no_update. Nvhost will notice this manual syncpoint increment, and will call back to gk20a_channel_update, which will clean up the job. With semaphore synchronization, we don't have anybody calling back to gk20a_channel_update, so we need to call it ourselves. Release job semaphores (the equivalent of set_min_eq_max) on gk20a_disable_channel_no_update, and if any semaphores were released, call gk20a_channel_update afterwards. Because we are actually calling gk20a_channel_update in some situations, gk20a_disable_channel_no_update is no longer an appropriate name for the function. Rename it to gk20a_channel_abort.

* gpu: nvgpu: Set ch error before channel disableTerje Bergstrom2015-03-18
| | | | | | | | | | | | | | | | | | | In error case we first disabled the channel, and reset sync point to max. After this we set channel error state. This causes a race if channel is closed between setting sync point and setting channel state. Rearrange the code so that error state is set first, and only then channel is disabled.

* gpu: nvgpu: Fault engines on PBDMA errorTerje Bergstrom2015-03-18
| | | | | | | | | | | | | | | | On PBDMA error even though the engine might not be wedged, we need to kick the channel out of engine. Add that logic. Also when channel is not in engine, we need to remove it from runlist.
