* gpu: nvgpu: hold power ref for deterministic channelsKonsta Holtta2017-06-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To support deterministic channels even with platforms where railgating is supported, have each deterministic-marked channel hold a power reference during their lifetime, and skip taking power refs for jobs in submit path for those. Previously, railgating blocked deterministic submits in general because of gk20a_busy()/gk20a_idle() calls in submit path possibly taking time and more significantly because the gpu may need turning on which takes a nondeterministic and long amount of time. As an exception, gk20a_do_idle() can still block deterministic submits until gk20a_do_unidle() is called. Add a rwsem to guard this. VPR resize needs do_idle, which conflicts with deterministic channels' requirement to keep the GPU on. This is documented in the ioctl header now. Make NVGPU_GPU_FLAGS_SUPPORT_DETERMINISTIC_SUBMIT_NO_JOBTRACKING always set in the gpu characteristics now that it's supported. The only thing left now blocking NVGPU_GPU_FLAGS_SUPPORT_DETERMINISTIC_SUBMIT_FULL is the sync framework. Make the channel debug dump show which channels are deterministic.

* gpu: nvgpu: expose deterministic submit supportKonsta Holtta2017-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | Add these bits in the gpu characteristics flags: NVGPU_GPU_FLAGS_SUPPORT_DETERMINISTIC_SUBMIT_NO_JOBTRACKING - fast submits with no in-kernel job tracking are supported. NVGPU_GPU_FLAGS_SUPPORT_DETERMINISTIC_SUBMIT_FULL - deterministic submits also with job tracking and num_inflight_jobs set are supported. Either of these may get disabled if the particular channel or submit still requires features that block these. Make gk20a_channel_sync_needs_sync_framework() take a gk20a pointer instead of a channel pointer so that it can be called without a channel. It does not need any per-channel data.

* gpu: nvgpu: remove fence dependency trackingKonsta Holtta2017-04-11
| | | | | | | | | | | | | | | | | | | | In preparation for better abstraction in job synchronization, drop support for the dependency fences tracked via submit pre-fences in semaphore-based syncs. This has only worked for semaphores, not nvhost syncpoints, and hasn't really been used. The dependency was printed in the sync framework's sync pt value string. Remove also the userspace-visible gk20a_sync_pt_info which is not used and depends on this feature (providing a duration since the dependency fence's timestamp).

NVGPU_CHANNEL_GR_ERROR_SW_METHOD (12), NVGPU_CHANNEL_GR_EXCEPTION(13) and NVGPU_CHANNEL_FECS_ERR_UNIMP_FIRMWARE_METHOD (37) are new error notifiers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change makes the invocation of the deferred job clean-up mechanism conditional. For submissions that require job tracking, deferred clean-up is only required if any of the following conditions are met: 1) Channel's deterministic flag is not set 2) Rail-gating is enabled 3) Channel WDT is enabled 4) Buffer refcounting is enabled 5) Dependency on Sync Framework In case deferred clean-up is not needed, we clean-up a single job tracking resource in the submit path. For deterministic channels, we do not allow deferred clean-up to occur and fail any submits that require it.
