* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
