* gpu: nvgpu: Cleanup usage of bypass_smmuAlex Waterman2018-02-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The GPU has multiple different operating modes in respect to IOMMU'ability. As such there needs to be a clean way to tell the driver whether it is IOMMU'able or not. This state also does not always reflect what is possible: all becasue the GPU can generate IOMMU'ed memory requests doesn't mean it wants to. The nvgpu_iommuable() API has now existed for a little while which is a useful way to convey whether nvgpu should consider the GPU as IOMMU'able. However, there is also the g->mm.bypass_smmu flag which used to be able to override what the GPU decided it should do. Typically it was assigned the same value as nvgpu_iommuable() but that was not necessarily a requirment. This patch removes all the usages of g->mm.bypass_smmu and instead uses the nvgpu_iommuable() function. All places where the check against g->mm.bypass_smmu have been replaced with nvgpu_iommuable(). The code should now be much cleaner. Subsequently other checks can also be placed in the nvgpu_iommuable() function. For example, when NVLINK comes online and the GPU should no longer consider DMA addresses and instead use scatter-gather lists directly the ngpu_iommuable() function will be able to check the state of NVLINK and then act accordingly.

* gpu: nvgpu: Add translation for NVGPU MM flagsAlex Waterman2017-11-17
| | | | | | | | | | | | | | | | | | | | | | | Add a translation layer to convert from the NVGPU_AS_* flags to to new set of NVGPU_VM_MAP_* and NVGPU_VM_AREA_ALLOC_* flags. This allows the common MM code to not depend on the UAPI header defined for Linux. In addition to this change a couple of other small changes were made: 1. Deprecate, print a warning, and ignore usage of the NVGPU_AS_MAP_BUFFER_FLAGS_MAPPABLE_COMPBITS flag. 2. Move the t19x IO coherence flag from the t19x UAPI header to the regular UAPI header.
