* gpu: nvgpu: gk20a: Update perfmon initPrashant Malani2015-03-18
| | | | | | | | | | | | | | | | | Make the perfmon sampling configurable, by adding an 'enabled' flag. This is set according to the CONFIG initially. Modify the perfmon event handler to not touch clock rates. Add a counter to count the number of perfmon events. Also add debugfs entries for the above.

* gpu: nvgpu: Remove redundant locked variableArto Merilainen2015-03-18
| | | | | | | | | | | | | | | | Queue locked variable holds entirely redundant information about the queue status and having the variable causes a race between lock() and unlock() functions. This patch removes the locked variable.
