* gpu: nvgpu: Correction in allow_all flag usagesujeet baranwal2015-06-06
| | | | | | | | | | | | | | | | | The allow_all flag is used to avoid any kind of register's offset being validate when called through regops. but the current implementation was flawed. It printed error messages and set the status of each operation invalid, even when allow_all was set.

* gpu: nvgpu: ioctl for flushing GPU L2sujeet baranwal2015-04-04
| | | | | | | | | | | | | | CUDA devtools need to be able to flush the GPU's cache in a sideband fashion and so cannot use methods. This change implements an nvgpu_gpu_ioctl to flush and optionally invalidate the GPU's L2 cache and flush fb.

* gpu: nvgpu: validate reg ops alwaysKonsta Holtta2015-04-04
| | | | | | | | | | | | | | | Call validate_reg_ops() even when allow_all is set, since that function takes care of counting ctxsw regops which would not be executed without the counters set.
