* gpu: nvgpu: add NO_KERNEL_MAPPING for alloc_map_vidKonsta Holtta2017-03-27
| | | | | | | | | | | | | | | | | | Commit 8f3875393e7a6bd0fc03afdb1fa99b7e33b71576 ("abstract away dma alloc attrs") added an implicit NVGPU_DMA_NO_KERNEL_MAPPING for the function that allocates vidmem buffers, but the functions gk20a_gmmu_alloc_map_vid and gk20a_gmmu_alloc_map got overlooked and use no flags which now triggers a warning. Make those cases alloc the vidmem buffer with the no kernel mapping flag as it should have been, because kernel mappings of vidmem are not supported.

* gpu: nvgpu: Use nvgpu_timeout for all loopsTerje Bergstrom2017-03-27
| | | | | | | | | | | | | | | | | | | | There were still a few remaining loops where we did not use nvgpu_timeout and required Tegra specific functions for detecting if timeout should be skipped. Replace all of them with nvgpu_timeout and remove including chip-id.h where possible. FE power mode timeout loop also used wrong delay value. It always waited for the whole max timeout instead of looping with smaller increments. If SEC2 ACR boot fails to halt, we should not try to check ACR result from mailbox. Add an early return for that case. JIRA NVGPU-16 Change-Id: I9f0984250d7d01785755338e39822e6631dcaa5a Signed-off-by: Terje Bergstrom <tbergstrom@nvidia.com> Reviewed-on: http://git-master/r/1323227

* gpu: nvgpu: refactor teardown to support unbindDavid Nieto2017-03-25
| | | | | | | | | | | | | | | | | | | | | | | | This change refactors the teardown in remove to ensure that it is possible to unload the driver while leaving fds open. This is achieved by making sure that the SW state is kept alive till all fds are closed and by checking that subsequent calls to ioctls after the teardown fail. Normally, this would be achieved ny calls into gk20a_busy(), but in kickoff we dont call into that to reduce latency, so we need to check the driver status directly, and also in some of the functions as we need to make sure the ioctl does not dereference the device or platform struct bug 200277762 JIRA: EVLR-1023 Change-Id: I163e47a08c29d4d5b3ab79f0eb531ef234f40bde Signed-off-by: David Nieto <dmartineznie@nvidia.com> Reviewed-on: http://git-master/r/1320219 Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com> Reviewed-by: svccoveritychecker <svccoveritychecker@nvidia.com> Reviewed-by: Shreshtha Sahu <ssahu@nvidia.com> Reviewed-by: Vijayakumar Subbu <vsubbu@nvidia.com>

* gpu: nvgpu: abstract away dma alloc attrsKonsta Holtta2017-03-21
| | | | | | | | | | | | | | | | | | | | | | | | Don't use enum dma_attr in the gk20a_gmmu_alloc_attr* functions, but define nvgpu-internal flags for no kernel mapping, force contiguous, and read only modes. Store the flags in the allocated struct mem_desc and only use gk20a_gmmu_free, remove gk20a_gmmu_free_attr. This helps in OS abstraction. Rename the notion of attr to flags. Add implicit NVGPU_DMA_NO_KERNEL_MAPPING to all vidmem buffers allocated via gk20a_gmmu_alloc_vid for consistency. Fix a bug in gk20a_gmmu_alloc_map_attr that dropped the attr parameter accidentally.
