* gpu: nvgpu: Cleanup generic MM code in gk20a/mm_gk20a.cAlex Waterman2017-10-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move much of the remaining generic MM code to a new common location: common/mm/mm.c. Also add a corresponding <nvgpu/mm.h> header. This mostly consists of init and cleanup code to handle the common MM data structures like the VIDMEM code, address spaces for various engines, etc. A few more indepth changes were made as well. 1. alloc_inst_block() has been added to the MM HAL. This used to be defined directly in the gk20a code but it used a register. As a result, if this register hypothetically changes in the future, it would need to become a HAL anyway. This path preempts that and for now just defines all HALs to use the gk20a version. 2. Rename as much as possible: global functions are, for the most part, prepended with nvgpu (there are a few exceptions which I have yet to decide what to do with). Functions that are static are renamed to be as consistent with their functionality as possible since in some cases function effect and function name have diverged.

* gpu: nvgpu: Convert VIDMEM work_struct to threadAlex Waterman2017-10-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert the work_struct used by the vidmem background clearing to a thread to make it more cross platform. The thread waits on a condition variable to determine when work needs to be done. The signal comes from the DMA API when it enqueues a new nvgpu_mem that needs clearing. Add logic for handling suspend: the CE cannot be accessed while the GPU is suspended. As such the background thread must be paused while the GPU is suspended and the CE is not available. Several other changes were also made: o Move the code that enqueues a nvgpu_mem from the DMA API code to a function in the VIDMEM code. o Move nvgpu_vidmem_get_pending_alloc() to the Linux specific code as this function is only used there. It's a trivial function that QNX can easily implement as well. o Remove the was_empty logic from the enqueue. Now just always signal the condition variable when anew nvgpu_mem comes in. o Move CE suspend to after MM suspend.

* gpu: nvgpu: Move dma_buf usage from mm_gk20a.cAlex Waterman2017-10-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move most of the dma_buf usage present in the mm_gk20a.c code out to Linux specific code and some commom/mm code. There's two primary groups of code: 1. dma_buf priv field code (for holding comptag data) 2. Comptag usage that relies on dma_buf pointers For (1) the dma_buf code was simply moved to common/linux/dmabuf.c since most of this code is clearly Linux specific. The comptag code was a bit more complicated since there is two parts to the comptag code. Firstly there's the code that manages the comptag memory. This is essentially a simple allocator. This was moved to common/mm/comptags.c since it can be shared across all chips. The second set of code is moved to common/linux/comptags.c since it is the interface between dma_bufs and the comptag memory. Two other fixes were done as well: - Add struct gk20a to the comptag allocator init so that the proper nvgpu_vzalloc() function could be used. - Add necessary includes to common/linux/vm_priv.h.

When an iGPU is behind and IOMMU it can pick whether to use that IOMMU for translation by adding a bit to physical addresses. This function takes care of that. However, this required an abstracted nvgpu_iommuable() API to check whether a GPU is behind an IOMMU. This patch adds that API for Linux.

* 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.
