* gpu: nvgpu: Remove sg_phys() from GMMU codeAlex Waterman2017-10-04
| | | | | | | | | | | | | | | | | | Remove the last sg_phys() call from the GMMU code and replace it with a generic nvgpu_mem API. This new API, nvgpu_mem_get_phys_addr(), returns the physical address of an nvgpu_mem struct. Also, implement this new API in the Linux specific nvgpu_mem code since it requires access to the underlying SGT/SGL.

* gpu: nvgpu: SGL passthrough implementationSunny He2017-09-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | The basic nvgpu_mem_sgl implementation provides support for OS specific scatter-gather list implementations by simply copying them node by node. This is inefficient, taking extra time and memory. This patch implements an nvgpu_mem_sgt struct to act as a header which is inserted at the front of any scatter- gather list implementation. This labels every struct with a set of ops which can be used to interact with the attached scatter gather list. Since nvgpu common code only has to interact with these function pointers, any sgl implementation can be used. Initialization only requires the allocation of a single struct, removing the need to copy or iterate through the sgl being converted.

* gpu: nvgpu: nvgpu SGL implementationAlex Waterman2017-09-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The last major item preventing the core MM code in the nvgpu driver from being platform agnostic is the usage of Linux scattergather tables and scattergather lists. These data structures are used throughout the mapping code to handle discontiguous DMA allocations and also overloaded to represent VIDMEM allocs. The notion of a scatter gather table is crucial to a HW device that can handle discontiguous DMA. The GPU has a MMU which allows the GPU to do page gathering and present a virtually contiguous buffer to the GPU HW. As a result it makes sense for the GPU driver to use some sort of scatter gather concept so maximize memory usage efficiency. To that end this patch keeps the notion of a scatter gather list but implements it in the nvgpu common code. It is based heavily on the Linux SGL concept. It is a singly linked list of blocks - each representing a chunk of memory. To map or use a DMA allocation SW must iterate over each block in the SGL. This patch implements the most basic level of support for this data structure. There are certainly easy optimizations that could be done to speed up the current implementation. However, this patches' goal is to simply divest the core MM code from any last Linux'isms. Speed and efficiency come next.

| | | | | | | | | | | | | | | | | | | | | | | | | Make the kmem debugging prints much more easily usable. Previously the prints would only take effect if the full tracking was enabled: CONFIG_NVGPU_TRACK_MEM_USAGE However, there are many times when just the debug prints would be nice to have by simply setting the log mask bit in the log mask. echo 0x80000 > /sys/kernel/debug/<gpu>/log_mask Also this change now uses the real nvgpu_log() function instead of the legacy nvgpu_dbg() function. This makes the logging appear with proper GPU printing as well.

In particular, in this mode, the userspace will tell the kernel whether the kind is compressible, and if so, what is the incompressible fallback kind. By supplying only the compressible kind, the userspace can require that the map kind will not be demoted to the incompressible fallback kind in case of comptag allocation failure. Add also a GPU characteristics flag NVGPU_GPU_FLAGS_SUPPORT_MAP_DIRECT_KIND_CTRL to signal whether direct kind control is supported. Fix indentation of nvgpu_as_map_buffer_ex_args header comment.
