* gpu: nvgpu: sync_framework cleanupsDebarshi Dutta2018-04-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch deals with cleanups meant to make things simpler for the upcoming os abstraction patches for the sync framework. This patch causes some substantial changes which are listed out as follows. 1) sync_timeline is moved out of gk20a_fence into struct nvgpu_channel_linux. New function pointers are created to facilitate os independent methods for enabling/disabling timeline and are now named as os_fence_framework. These function pointers are located in the struct os_channel under struct gk20a. 2) construction of the channel_sync require nvgpu_finalize_poweron_linux() to be invoked before invocations to nvgpu_init_mm_ce_context(). Hence, these methods are now moved away from gk20a_finalize_poweron() and invoked after nvgpu_finalize_poweron_linux(). 3) sync_fence creation is now delinked from fence construction and move to the channel_sync_gk20a's channel_incr methods. These sync_fences are mainly associated with post_fences. 4) In case userspace requires the sync_fences to be constructed, we try to obtain an fd before the gk20a_channel_submit_gpfifo() instead of trying to do that later. This is used to avoid potential after effects of duplicate work submission due to failure to obtain an unused fd.

* gpu: nvgpu: support per-channel wdt timeoutsKonsta Holtta2018-03-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace the padding in nvgpu_channel_wdt_args with a timeout value in milliseconds, and add NVGPU_IOCTL_CHANNEL_WDT_FLAG_SET_TIMEOUT to signify the existence of this new field. When the new flag is included in the value of wdt_status, the field is used to set a per-channel timeout to override the per-GPU default. Add NVGPU_IOCTL_CHANNEL_WDT_FLAG_DISABLE_DUMP to disable the long debug dump when a timed out channel gets recovered by the watchdog. Printing the dump to serial console takes easily several seconds. (Note that there is NVGPU_TIMEOUT_FLAG_DISABLE_DUMP about ctxsw timeout separately for NVGPU_IOCTL_CHANNEL_SET_TIMEOUT_EX as well.) The behaviour of NVGPU_IOCTL_CHANNEL_WDT is changed so that either NVGPU_IOCTL_CHANNEL_ENABLE_WDT or NVGPU_IOCTL_CHANNEL_DISABLE_WDT has to be set. The old behaviour was that other values were silently ignored. The usage of the global default debugfs-controlled ch_wdt_timeout_ms is changed so that its value takes effect only for newly opened channels instead of in realtime. Also, zero value no longer means that the watchdog is disabled; there is a separate flag for that after all. gk20a_fifo_recover_tsg used to ignore the value of "verbose" when no engines were found. Correct this.

* 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.

| | | | | | | | | | | | | | | | | | | | This patch begins splitting out the VM implementation from mm_gk20a.c and moves it to common/linux/vm.c and common/mm/vm.c. This split is necessary because the VM code has two portions: first, an interface for the OS specific code to use (i.e userspace mappings), and second, a set of APIs for the driver to use (init, cleanup, etc) which are not OS specific. This is only the beginning of the split - there's still a lot of things that need to be carefully moved around.
