* gpu: nvgpu: Fix more pmu circular dependenciesAlex Waterman2017-02-07
| | | | | | | | | | | | | | | | Similar to patch 67fc4629892ab60d6335752b93d883ef690f1ea4 fix more circular dependencies arising from #include'ing gk20a.h for no apparent reason. Bug 200192125 Coverity ID 2011397 Coverity ID 2011398 Change-Id: I75bcb3e4e66b680498b0e20d645ab9543aae6697 Signed-off-by: Alex Waterman <alexw@nvidia.com> Reviewed-on: http://git-master/r/1296947 Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com>
* gpu: nvgpu: Remove circular dependency in PMU includesTerje Bergstrom2017-01-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove including gk20a.h from pmu_gk20a.h. This causes a fallout as some #includes were missing. gr_gp10b.h uses mem_desc, but did not include mm_gk20a.h. Add the include. Including mm_gk20a.h in gr_gp10b.h causes recursive include, as mm_gk20a.h has some gr defines. Move the defines to gr_gk20a.h to remove the dependency. gr_ctx_gk20a.h used struct gk20a pointers, but did not forward declare it. Add a forward declaration. gr_gk20a.h uses dbg_session_gk20a, but was missing forward declaration. gr_gk20a.h did not include nvgpu.h but it uses preemption types from that header. Add include.

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().

* gpu: nvgpu: Support multiple types of allocatorsAlex Waterman2016-07-19
| | | | | | | | | | | | | | | | | | | | | | Support multiple types of allocation backends. Currently there is only one allocator implementation available: a buddy allocator. Buddy allocators have certain limitations though. For one the allocator requires metadata to be allocated from the kernel's system memory. This causes a given buddy allocation to potentially sleep on a kmalloc() call. This patch has been created so that a new backend can be created which will avoid any dynamic system memory management routines from being called.

* gpu: nvgpu: use vidmem by default in gmmu_alloc variantsKonsta Holtta2016-07-08
| | | | | | | | | | | | | | | | | | For devices that have vidmem available, use the vidmem allocator in gk20a_gmmu_alloc{,attr,_map,_map_attr}. For others, use sysmem. Because all of the buffers haven't been tested to work in vidmem yet, rename calls to gk20a_gmmu_alloc{,attr,_map,_map_attr} to have _sys at the end to declare explicitly that vidmem is used. Enabling vidmem for each now is a matter of removing "_sys" from the function call.
