* gpu: nvgpu: move header location of gk20a.hDebarshi Dutta2018-09-25
| | | | | | | | | | | | | | | | | | | | | | | 1) Update header path of gk20a.h files present in os/ to <nvgpu/gk20a.h> 2) os_fence_android_sema.c indirectly was dependent on gk20a.h via semaphore.h. So, added #include <nvgpu/gk20a.h> in os_fence_android_sema.c and replaced the header with forward declaration of struct gk20a in semaphore.h Jira NVGPU-597 Change-Id: I96e23befeb80713f3a399071eb5498f6f580211d Signed-off-by: Debarshi Dutta <ddutta@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1842868 Reviewed-by: svc-misra-checker <svc-misra-checker@nvidia.com> GVS: Gerrit_Virtual_Submit Reviewed-by: Konsta Holtta <kholtta@nvidia.com> Reviewed-by: Automatic_Commit_Validation_User Reviewed-by: Alex Waterman <alexw@nvidia.com> Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
* gpu: nvgpu: changing page_idx from int to u64Sai Nikhil2018-09-07
| | | | | | | | | | | | | | | | | | | | | page_idx is an element of the struct nvgpu_semaphore_pool, defined in include/nvgpu/semaphore.h file. page_idx can not be negative so changing it from int to u64 and its related changes in various files. This also fixes MISRA 10.4 violations in these files.

* gpu: nvpgu: Rename Linux specific vidmem codeTerje Bergstrom2018-07-06
| | | | | | | | | | | | | | | | Rename os/linux/vidmem.c to os/linux/dmabuf_vidmem.c. The code is mainly dealing with interfacing with Linux dmabuf framework and its responsibilities got confused with common/mm/vidmem.c. Also move the header include/nvgpu/linux/vidmem.h to os/linux/dmabuf_vidmem.h. It does not expose any interface to outside Linux code.

* gpu: nvgpu: Implement common nvgpu_mem_rd* functionsTerje Bergstrom2018-07-02
| | | | | | | | | | | | | | | | | nvgpu_mem_rd*() functions were implemented per OS. They also used nvgpu_pramin_access_batched() and implemented a big portion of logic for using PRAMIN in OS specific code. Make the implementation for the functions generic. Move all PRAMIN logic to PRAMIN and simplify the interface provided by PRAMIN.
