* gpu: nvgpu: Standardize HAS_SYNCPOINTs checkAlex Waterman2018-09-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Nvgpu uses many ways to check if sync points are enabled. The four ways used to be: platform->has_syncpoints g->has_syncpoints nvgpu_is_enabled(g, NVPGU_HAS_SYNCPOINTS) gk20a_platform_has_syncpoints() This patch standardizes all usage to now be nvgpu_has_syncpoints() which is based on gk20a_platform_has_syncpoints() - just renamed to be general to nvgpu. All usage of the other forms have now been consolidated. However, under the hood nvgpu_has_syncpoints() does check the is_enabled flag. This flag is now set where g->has_syncpoints used to be set based on the platform data. The basic dependency chain is this: nvgpu_has_syncpoints -> NVGPU_HAS_SYNCPOINTS -> platform->has_syncpoints However, note: there are several places where syncpoints can be disabled if some other driver initialization fails (for ex. host1x). Also note that nvgpu_has_syncpoints() also considers a disable variable set by debugfs.

* 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: move channel header to commonKonsta Holtta2018-09-05
| | | | | | | | | | | | | channel_gk20a is clear from chip specifics and from most dependencies, so move it under the common directory.

* gpu: nvgpu: Changed enum gmmu_pgsz_gk20a into macrosAmulya2018-08-22
| | | | | | | | | | | | | | | | | | Changed the enum gmmu_pgsz_gk20a into macros and changed all the instances of it. The enum gmmu_pgsz_gk20a was being used in for loops, where it was compared with an integer. This violates MISRA rule 10.4, which only allows arithmetic operations on operands of the same essential type category. Changing this enum into macro will fix this violation.

* gpu: nvgpu: Update Linux side VM code for API solidificationAlex Waterman2018-06-22
| | | | | | | | | | | | | | | | | | | | | | Update the Linux specific code to match the MM API docs in the previous patch. The user passed page size is plumbed through the Linux VM mapping calls but is ultimately ignored once the core VM code is called. This will be handled in the next patch. This also adds some code to make the CDE page size picking happen semi-intelligently. In many cases the CDE buffers can be mapped with large pages.

* gpu: nvgpu: Move Linux files away from commonTerje Bergstrom2018-06-15
Move all Linux source code files to drivers/gpu/nvgpu/os/linux from drivers/gpu/nvgpu/common/linux. This changes the meaning of common to be OS independent.
