* gpu: nvgpu: rename has_timedout and make it thread safeSeema Khowala2019-02-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently has_timedout variable is protected by wmb at places where it is being set and there is no correspoding rmb whenever has_timedout variable is read. This is prone to errors for concurrent execution. This change is supposed to fix this issue. Rename has_timedout variable of channel struct to ch_timedout. Also to avoid rmb every time ch_timedout is read, ch_timedout_spinlock is added to protect ch_timedout variable for taking care of concurrent execution.

* gpu: nvgpu: replace input param chid with pointer to channelDebarshi Dutta2019-02-11
| | | | | | | | | | | | | | | | | | | | | | | | | preempt_channel needs to use the channel to pass it to other public functions, get access to a tsg etc. This qualifies it to take a pointer to a channel as an input parameter instead of a chid. Increment the channel ref counter using the function gk20a_channel_from_id in functions where we get the chid from the h/w registers directly. Once the prempt_channel function call is done, use a gk20a_channel_put on the referenced channel.

* gpu: nvgpu: add safe channel id lookupKonsta Holtta2019-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add gk20a_channel_from_id() to retrieve a channel, given a raw channel ID, with a reference taken (or NULL if the channel was dead). This makes it harder to mistakenly use a channel that's dead and thus uncovers bugs sooner. Convert code to use the new lookup when applicable; work remains to convert complex uses where a ref should have been taken but hasn't. The channel ID is also validated against FIFO_INVAL_CHANNEL_ID; NULL is returned for such IDs. This is often useful and does not hurt when unnecessary. However, this does not prevent the case where a channel would be closed and reopened again when someone would hold a stale channel number. In all such conditions the caller should hold a reference already. The only conditions where a channel can be safely looked up by an id and used without taking a ref are when initializing or deinitializing the list of channels.

* gpu: nvgpu: fix double handling in timeoutKonsta Holtta2019-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The context switch timeout works by triggering a hardware timeout at 10 Hz. When handling these, we check whether a channel has actually timed out. Currently the timeout limit can be shorter than the 10 Hz interval which always causes us to recover a channel but would also cause detection of progress if there was any in the interval. Handling both situations at the same time would reuse the channel pointer local to the function after a loop has finished and would cause memory corruption. Fix this by making the two branches mutually exclusive, and move the recover case to happen first because that's how our tests assume things to work.

* gpu: nvgpu: Standardize HAS_SYNCPOINTs checkAlex Waterman2018-09-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Nvgpu uses many ways to check if sync points are enabled. The four ways used to be: platform->has_syncpoints g->has_syncpoints nvgpu_is_enabled(g, NVPGU_HAS_SYNCPOINTS) gk20a_platform_has_syncpoints() This patch standardizes all usage to now be nvgpu_has_syncpoints() which is based on gk20a_platform_has_syncpoints() - just renamed to be general to nvgpu. All usage of the other forms have now been consolidated. However, under the hood nvgpu_has_syncpoints() does check the is_enabled flag. This flag is now set where g->has_syncpoints used to be set based on the platform data. The basic dependency chain is this: nvgpu_has_syncpoints -> NVGPU_HAS_SYNCPOINTS -> platform->has_syncpoints However, note: there are several places where syncpoints can be disabled if some other driver initialization fails (for ex. host1x). Also note that nvgpu_has_syncpoints() also considers a disable variable set by debugfs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch constructs clk_arbiter specific code for gp10b as well as gv11b and does the necessary plumbing in the clk_arbiter code. The changes made are as follows. 1) Constructed clk_arb_gp10b.* files which add support for clk_arb related HALS including the nvgpu_clk_arb_init and nvgpu_clk_arb_cb. This doesn't have support for debugfs nor the VFUpdateEvent yet and consequently no support for arb->notifications. 2) Added gpcclk specific variables corresponding to every gpc2clk in a given clk_arb related struct. 3) Linux specific support_clk_freq_controller is assigned true in platform_gp10b.c and platform_gv11b.c files. 4) Incremented the clk_arb_worker.put atomic variable during worker_deinit so as to allow the worker thread to be stopped. 5) Added the flag clk_arb_events_supported as part of struct nvgpu_clk_arb. This flag is used to selectively account for the extra refcounting present in OS specific code i.e. nvgpu_clk_arb_commit_request_fd. For igpus, the extra refcount is reduced during nvgpu_clk_arb_release_completion_dev.
