* gpu: nvgpu: Move sim support to its own fileTerje Bergstrom2017-03-21
| | | | | | | | | | | Simulator support is intermixed with the rest of code in gk20a.c. Move that code away from gk20a.c to an own file.

* gpu: nvgpu: Implement get_rate/set_rate as GPU opTerje Bergstrom2017-03-16
| | | | | | | | | | | | | | | | | | | Move clock APIs from gk20a_platform to gpu_ops. At the same time allow use of internal get_rate/set_rate for querying both GPCCLK and PWRCLK on iGPU. At the same time we can replace calls to clk framework with the new HAL and drop direct dependency to clk framework. gp10b ops were replaced as a whole at HAL initialization. That replaces anything set in platform probe stage, so reduce that to touch only clock gating regs.

* gpu: nvgpu: Generalize BIOS codeTerje Bergstrom2017-02-17
| | | | | | | | | | | | | | | | | | Most of BIOS parsing code is not specific to any particular GPU. Move most of the code to generic files, and leave only chip specific parts dealing with microcontroller boot into chip specific files. As most of the parsing is generic, they do not need to be called via HALs so remove the HALs and change the calls into direct function calls. All definitions meant to be used outside BIOS code itself are now in <nvgpu/bios.h> Change-Id: Id48e94c74511d6e95645e90e5bba5c12ef8da45d Signed-off-by: Terje Bergstrom <tbergstrom@nvidia.com> Reviewed-on: http://git-master/r/1302222 GVS: Gerrit_Virtual_Submit

* gpu: nvgpu: Organize semaphore_gk20a.[ch]Alex Waterman2017-02-13
| | | | | | | | | | | | | | | | | | | | | | | Move semaphore_gk20a.c drivers/gpu/nvgpu/common/ since the semaphore code is common to all chips. Move the semaphore_gk20a.h header file to drivers/gpu/nvgpu/include/nvgpu and rename it to semaphore.h. Also update all places where the header is inluced to use the new path. This revealed an odd location for the enum gk20a_mem_rw_flag. This should be in the mm headers. As a result many places that did not need anything semaphore related had to include the semaphore header file. Fixing this oddity allowed the semaphore include to be removed from many C files that did not need it.

* gpu: nvgpu: Move kmem_caches to allocatorAlex Waterman2017-02-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of using a single static kmem_cache for each type of data structure the allocators may want to allocate each allocator now has its own instance of the kmem_cache. This is done so that each GPU driver instance can accurately track how much memory it is using. In order to support this on older kernels a new NVGPU API has been made, nvgpu_kmem_cache_create(struct gk20a *g, size_t size) To handle the possibility that caches cannot be created with the same name. This patch also fixes numerous places where kfree() was wrongly used to free kmem_cache allocs.

| | | | | | | | | | | | | | | | | | | Move the GPU allocators to common/mm/ since the allocators are common code across all GPUs. Also rename the allocator code to move away from gk20a_ prefixed structs and functions. This caused one issue with the nvgpu_alloc() and nvgpu_free() functions. There was a function for allocating either with kmalloc() or vmalloc() depending on the size of the allocation. Those have now been renamed to nvgpu_kalloc() and nvgpu_kfree().

It works by allocating chunks from an underlying buddy allocator and collating the chunks together (similar to what an sgt does in the wider Linux kernel). This handles the ability to get large buffers in potentially fragmented memory. The GMMU can then obviously map the physical vidmem into contiguous GVA spaces.
