* gpu: nvgpu: fix NVGPU_COND_WAIT_INTERRUPTIBLEThomas Fleury2019-10-11
| | | | | | | | | | | | | | | | | | | | | | | | When called with timeout=0, NVGPU_COND_WAIT_INTERRUPTIBLE macro ignores the return code from wait_event_interruptible. As a result we do not detect when the call is interrupted, and the calling process hangs. Use wait_event_interruptible return code in case of infinite timeout.

* gpu: nvgpu: Fix PMU destroy sequenceAbhiroop Kaginalkar2019-09-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A call to exit the PMU state machine/kthread must be prioritized over any other state change. It was possible to set the state as PMU_STATE_EXIT, signal the kthread and overwrite the state before the kthread has had the chance to exit its loop. This may lead to a "lost" signal, resulting in indefinite wait during the destroy sequence. Faulting sequence: 1. pmu_state = PMU_STATE_EXIT in nvgpu_pmu_destroy() 2. cond_signal() 3. pmu_state = PMU_STATE_LOADING_PG_BUF 4. PMU kthread wakes up 5. PMU kthread processes PMU_STATE_LOADING_PG_BUF 6. PMU kthread sleeps 7. nvgpu_pmu_destroy() waits indefinitely This patch adds a sticky flag to indicate PMU_STATE_EXIT, irrespective of any subsequent changes to pmu_state. The PMU PG init kthread may wait on a call to NVGPU_COND_WAIT_INTERRUPTIBLE, which requires a corresponding call to nvgpu_cond_signal_interruptible() as the core kernel code requires this task mask to wake-up an interruptible task.

* nvgpu: don't report max load when counter overflowLeon Yu2019-08-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This is to prevent GPU (and thus EMC) frequency from being boosted from time to time when system is completely idle. It's caused by max GPU load being incorrectly reported by perfmon. When the issue happens, it can be observed that max load is reported but busy_cycles read from PMU is actually zero. Even though busy and total cycles returned by PMU may not be completely accurate when counter overflows, the counters accumulated so far still have some value that we shouldn't ignore. OTOH, returning max load could be the least accurate approximation in such cases. So let's just clear the interrupt status and let rest of the code handle the exception cases.

* gpu: nvgpu: use vpr resize APIVedashree Vidwans2019-08-30
| | | | | | | | | | | | | | | | | | | | This patch adds nvgpu API in linux and qnx to query vpr resize. The new API nvgpu_is_vpr_resize_enabled() is used in nvgpu_submit_channel_gpfifo(). Previously, if non-deterministic channel has timeout disabled and GPU cannot railgate on some platform, then channel doesn't power ref count and results in video freeze. This requires non-determinstic channel job tracking to be enabled if vpr resize is supported or if GPU can railgate.

* gpu: nvgpu: fix race for channel sync read/writeVedashree Vidwans2019-08-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CTS test dEQP-VK.api.object_management.max_concurrent.device_group crashes with invalid userspace memory access. Currently, nvgpu_submit_prepare_syncs() races with gk20a_channel_clean_up_jobs() and this race condition is exposed when aggressive_sync_destroy_thresh is set to non-zero value. nvgpu_submit_prepare_syncs() gets ref for c->sync to submit job and releases channel sync_lock immediately. Meanwhile, gk20a_channel_worker_process() triggers gk20a_channel_clean_up_jobs(), which destroys ref'd c->sync pointer. Channel sync is deleted by gk20a_channel_clean_up_jobs() only if aggressive_sync_destroy_thresh is non-zero. So, gk20a_channel_clean_up_jobs() and nvgpu_submit_prepare_syncs() will race only in this scenario. Hence, if aggressive_sync_destroy_thresh value is non-zero, this patch protects channel's sync pointer by holding channel sync_lock during complete execution of nvgpu_submit_prepare_syncs().

* gpu: nvgpu: Fix the race between runtime PM and L2 flushDebarshi Dutta2019-08-02
| | | | | | | | | | | | | | | | | | | | | | | | | | gk20a_mm_l2_flush flushes the L2 cache when "struct gk20a->power_on" is true. But it doesn't acquire power lock when doing that, which creates a race that runtime PM might suspend the GPU in the middle of L2 flush. The FB flush looks having the same issue with L2 flushing. This patch fixes that by calling pm_runtime_get_if_in_use at the beginning of the ioctl. This API from PM does a compare and add to the usage count. If the device was not in use, it simply returns without incrementing the usage count as its unnecessary to wake up the GPU(using e.g. a call to gk20a_busy()) as the caches are flushed when the device would be resumed anyways.

May be ctxsw already finished for the context for which ctxsw timeout intr was triggered. Possible Causes: a) On hitting engine reset, h/w drops the ctxsw_status to INVALID in fifo_engine_status register. Also while the engine is held in reset h/w passes busy/idle straight through. fifo_engine_status registers are correct in that there is no context switch outstanding as the CTXSW is aborted when reset is asserted. This is just a side effect of how gv100 and earlier versions of ctxsw_timeout behave. With gv10b and later, h/w snaps the context at the point of error so that s/w can see the tsg_id which caused the HW timeout. b) If engines are not busy and ctxsw state is valid then intr occurred in the past and if the ctxsw state has moved on to VALID from LOAD or SAVE, it means that whatever timed out eventually finished anyways. The problem with this is that s/w cannot conclude which context caused the problem as maybe more switches occurred before intr is handled.

* gpu: nvgpu: fix invalid TSG pointerDeepak Nibade2019-04-01
| | | | | | | | | | | | | | | | | | | | | | | | | | In gr_gp10b_set_cilp_preempt_pending() we already extract TSG pointer by calling tsg_gk20a_from_ch() which safely returns correct TSG or NULL in error case But before calling g->ops.fifo.post_event_id() we again extract TSG by directly accessing g->fifo.tsg array, and this could result in getting invalid TSG pointer Fix this by removing direct TSG extraction through g->fifo.tsg Bug 2444819 Jira NVGPU-1601 Change-Id: I9d49b5309c74e162828e7cb7d97556aae939a07c Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1984954 (cherry picked from commit dcd3778b5ea4e01ab1e5d2dab2b087b8da67b21e) Reviewed-on: https://git-master.nvidia.com/r/2077313 Reviewed-by: Automatic_Commit_Validation_User GVS: Gerrit_Virtual_Submit Reviewed-by: Bharat Nihalani <bnihalani@nvidia.com> Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>

| | | | | | | | | | | | | | | | | | | Multiple threads could be unbinding different channels from the same tsg at the same time. At the point where we remove the channel from the tsg's channel list, call disable_channel again, in case another thread had re-enabled the channel after we had disabled it.
