* gpu: nvgpu: Use busy looping on memory opsTerje Bergstrom2015-04-04
| | | | | | | | | | | | Use busy looping on L2 and TLB maintenance operations. This speeds them up by an order of magnitude. Add also trace points to measure performance for memory ops and interrupt processing.

* gpu: nvgpu: Per-chip interrupt processingTerje Bergstrom2015-03-18
Move accesses to MC registers under HAL so that they can be reimplemented per chip. Do chip detection and HAL initialization only once. Bug 1567274 Change-Id: I20bf2f439d267d284bfd536f1a1dfb5d5a2dce4c Signed-off-by: Terje Bergstrom <tbergstrom@nvidia.com> Reviewed-on: http://git-master/r/590385
