* gpu: nvgpu: gk20a: Add a gpfifo wait trace pointJanne Hellsten2015-04-04
| | | | | | | | | | | | | | | Add a couple of trace points for tracking when we need to wait for space in the gpfifo ring buffer. This wait can introduce significant latencies to rendering with large gpfifo entry inputs so it's good to be able to measure how often this path is taken.

| | | | | | | | | | | | | Implement NVGPU_AS_IOCTL_GET_VA_REGIONS which returns a list of GPU VA regions for different page sizes. This is required for the userspace for safe fixed-address address space allocation.

* video: tegra: host: Abstract gk20a channel synchronizationLauri Peltonen2015-03-18
| | | | | | | | | | | | | | | | Move all channel synchronization code to new channel_sync_gk20a.c/h files, and access all synchronization functions through function pointers. This is groundwork for supporting semaphore based channel synchronization.
