* gpu: nvgpu: vgpu: add freq capping supportSachit Kadle2017-06-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently callbacks from the PM_QOS framework (for thermal events), result in a RPC call to set GPU frequency. Since the governor will now be responsible for setting desired rate, the max PM_QOS callback will now cap the possible GPU frequency w/ a new RPC call to the server. The server is responsible for setting the ultimate frequency based on the cap & desired rates.

* gpu: nvgpu: hal for timestamps correlationThomas Fleury2017-06-15
| | | | | | | | | | | | | | | | | | | | | | | | In order to perform timestamps correlation for FECS traces, we need to collect GPU / GPU timestamps samples. In virtualization case, it is possible for a guest to get GPU timestamps by using read_ptimer. However, if the CPU timestamp is read on guest side, and the GPU timestamp is read on vm-server side, then it introduces some latency that will create an artificial offset for GPU timestamps (~2 us in average). For better CPU / GPU timestamps correlation, Added a command to collect all timestamps on vm-server side.

| | | | | | | | | | | | | | | | | | | | | | Begin removing all of the myriad flag variables in struct gk20a and replace that with one API that checks for flags being enabled or disabled. The API is as follows: bool nvgpu_is_enabled(struct gk20a *g, int flag); bool __nvgpu_set_enabled(struct gk20a *g, int flag, bool state); These APIs allow many of the gk20a flags to be replaced by defines. This makes flag usage consistent and saves a small amount of memory in struct gk20a. Also it makes struct gk20a easier to read since there's less clutter scattered through out.

| | | | | | | | | | | | | | | | Implement kmem abstraction and tracking in nvgpu. The abstraction helps move nvgpu's core code away from being Linux dependent and allows kmem allocation tracking to be done for Linux and any other OS supported by nvgpu.

* gpu: nvgpu: add worker for watchdog and job cleanupKonsta Holtta2017-03-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement a worker thread to replace the delayed works in channel watchdog and job cleanups. Watchdog runs by polling the channel states periodically, and job cleanup is performed on channels that are appended on a work queue consumed by the worker thread. Handling both of these two in the same thread makes it impossible for them to cause a deadlock, as has previously happened. The watchdog takes references to channels during checking and possibly recovering channels. Jobs in the cleanup queue have an additional reference taken which is released after the channel is processed. The worker is woken up from periodic sleep when channels are added to the queue. Currently, the queue is only used for job cleanups, but it is extendable for other per-channel works too. The worker can also process other periodic actions dependent on channels. Neither the semantics of timeout handling or of job cleanups are yet significantly changed - this patch only serializes them into one background thread. Each job that needs cleanup is tracked and holds a reference to its channel and a power reference, and timeouts can only be processed on channels that are tracked, so the thread will always be idle if the system is going to be suspended, so there is currently no need to explicitly suspend or stop it.
