* gpu: nvgpu: support gk20a virtualizationAingara Paramakuru2015-03-18
| | | | | | | | | | | | | The nvgpu driver now supports using the Tegra graphics virtualization interfaces to support gk20a in a virtualized environment. Bug 1509608 Change-Id: I6ede15ee7bf0b0ad8a13e8eb5f557c3516ead676 Signed-off-by: Aingara Paramakuru <aparamakuru@nvidia.com> Reviewed-on: http://git-master/r/440122 Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com> Tested-by: Terje Bergstrom <tbergstrom@nvidia.com>
* gpu: nvgpu: clear sparse in space freeKevin Huang2015-03-18
| | | | | | | | | | | | | | Gk20a unmaps the addresses binding to dummy page to clear sparse. On Gm20b, we need to free the allocated page table entry for sparse memory.

* gpu: nvgpu: Always initialize system vmTerje Bergstrom2015-03-18
| | | | | | | | | | | | | | | PMU, FECS and GPCCS use the same address space. We used to initialize the address space only if PMU is enabled. Create the system address space always. FECS and GPCCS used to have slower bit bang and faster DMA method for loading ucode. Slower method is needed when FECS and GPCCS do not have an address space. Remove the slower method as not anymore needed. Change-Id: I155619741ecc36aa6bf13a9c1ccb03c7c1330f0a Signed-off-by: Terje Bergstrom <tbergstrom@nvidia.com> Reviewed-on: http://git-master/r/406771

One thread starting an invalidate allows another thread to submit before invalidate is completed.
