| | | | | | | | | | | | | | | | | | | | | | Change nvgpu_kalloc() to nvgpu_big_[mz]alloc(). This is necessary since the natural free function name for this is nvgpu_kfree() but that conflicts with nvgpu_k[mz]alloc() (implemented in a subsequent patch). This API exists becasue not all allocation sizes can be determined at compile time and in some cases sizes may vary across the system page size. Thus always using kmalloc() could lead to OOM errors due to fragmentation. But always using vmalloc() is wastful of memory for small allocations. This API tries to alleviate those problems.

* 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.
