* gpu: nvgpu: replace __alloc_fd with tegra_fd_allocSri Krishna chowdary2017-04-26
| | | | | | | | | | | | | | nvgpu is being modularized for kernel-4.4 and newer kernels. __alloc_fd() can't be used on modules as it is not exported. So, use a wrapper tegra_fd_alloc() instead of __alloc_fd() bug 200290850 Change-Id: I0e63307d429774440753698643ba7620c1e1f9f6 Signed-off-by: Sri Krishna chowdary <schowdary@nvidia.com> Reviewed-on: http://git-master/r/1469313 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
* gpu: nvgpu: Move semaphore impl to nvgpu_memAlex Waterman2017-04-25
| | | | | | | | | | | | | | | | | | | Use struct nvgpu_mem for DMA allocations (and the corresponding nvgpu_dma_alloc_sys()) instead of custom rolled code. This migrates away from using linux scatter gather tables directly. Instead this is hidden in the nvgpu_mem struct. With this change the semaphore.c code no longer has any direct Linux dependencies.

It is useful for making nvgpu_mems that represent carveouts or other things like that.

* gpu: nvgpu: Add sub-nvgpu_memAlex Waterman2017-04-25
| | | | | | | | | | | | | | | | | | | | | | Add an API for creating a special sub-nvgpu_mem struct. This struct comes with some fairly important caveats but is very useful for the semaphore code. Also, make sure that in nvgpu_mem_begin() and nvgpu_mem_end() no additional mappings are made if not necessary. More importantly during nvgpu_mem_end() it would be possible to vunmap() a CPU mapping of a DMA allocation that does not expect this to happen.

* gpu: nvgpu: Fix submit profiling stat reportingPeter Boonstoppel2017-04-17
| | | | | | | | | | | | | | | | | | | The debugfs submit profiling stats report the distribution of submit times at different percentiles. The original code reports the lowest entry in every percentile-bin as being representative for that bin. This means that where debugfs reports the 50th percentile, it actually reports the ~45.001th percentile. This is especially inconveniant when looking at the 100th percentile, which does not in fact reflect the maximum. This patch changes the code to instead report the highest entry in every percentile-bin.
