* gpu: nvgpu: Use coherent aperture flagAlex Waterman2018-02-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using a coherent DMA API wee must make sure to program any aperture fields with the coherent aperture setting. To do this the nvgpu_aperture_mask() function was modified to take a third aperture mask argument, a coherent setting, so that code can use this function to generate coherent aperture settings. The aperture choice is some what tricky: the default version of this function uses the state of the DMA API to determine what aperture to use for SYSMEM: either coherent or non-coherent internally. Thus a kernel user need only specify the normal nvgpu_mem struct and the correct mask should be chosen. Due to many uses of nvgpu_mem structs not created directly from the DMA API wrapper it's easier to translate SYSMEM to SYSMEM_COH after creation. However, the GMMU mapping code, will encounter buffers from userspace with difference coerency attributes than the DMA API. Thus the __nvgpu_aperture_mask() really respects the aperture setting passed in regardless of the DMA API state. This aperture setting is pulled from NVGPU_VM_MAP_IO_COHERENT since this is either passed in from userspace or set by the kernel when using coherent DMA. The aperture field in attrs is upgraded to coh if this flag is set. This change also adds a coherent sysmem mask everywhere that it can. There's a couple places that do not have a coherent register field defined yet. These need to eventually be defined and added. Lastly the aperture mask code has been mvoed from the Linux vm.c code to the general vm.c code since this function has no Linux dependencies. Note: depends on https://git-master.nvidia.com/r/1664536 for new register fields.
