* gpu: nvgpu: move debugfs code to linux moduleDeepak Nibade2017-06-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since all debugfs code is Linux specific, remove it from common code and move it to Linux module Debugfs code is now divided into below module specific files : common/linux/debug.c common/linux/debug_cde.c common/linux/debug_ce.c common/linux/debug_fifo.c common/linux/debug_gr.c common/linux/debug_mm.c common/linux/debug_allocator.c common/linux/debug_kmem.c common/linux/debug_pmu.c common/linux/debug_sched.c Add corresponding header files for above modules too And compile all of above files only if CONFIG_DEBUG_FS is set Some more details of the changes made - Move and rename gk20a/debug_gk20a.c to common/linux/debug.c - Move and rename gk20a/debug_gk20a.h to include/nvgpu/debug.h - Remove gm20b/debug_gm20b.c and gm20b/debug_gm20b.h and call gk20a_init_debug_ops() directly from gm20b_init_hal() - Update all debug APIs to receive struct gk20a as parameter instead of receiving struct device pointer - Update API gk20a_dmabuf_get_state() to receive struct gk20a pointer instead of struct device - Include <nvgpu/debug.h> explicitly in all files where debug operations are used - Remove "gk20a/platform_gk20a.h" include from HAL files which no longer need this include - Add new API gk20a_debug_deinit() to deinitialize debugfs and call it from gk20a_remove() - Move API gk20a_debug_dump_all_channel_status_ramfc() to gk20a/fifo_gk20a.c Jira NVGPU-62 Change-Id: I076975d3d7f669bdbe9212fa33d98529377feeb6 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1488902 Reviewed-by: svccoveritychecker <svccoveritychecker@nvidia.com> GVS: Gerrit_Virtual_Submit Reviewed-by: Bharat Nihalani <bnihalani@nvidia.com>
* gpu: nvgpu: Last fixes for kmem usageAlex Waterman2017-05-14
| | | | | | | | | | | | | | | Remove the last usage of vmalloc() that slipped through the cracks. This was possible because depsite not including the vmalloc.h header directly it was implicitly included. Subsequent patches in this series fix the includes in the kmem header files such that this type of mistake will now be much harder.

* gpu: nvgpu: Remove unused variable and do_div()Alex Waterman2017-05-02

* gpu: nvgpu: Put debugfs dependencies inside #ifdefTerje Bergstrom2017-04-24
| | | | | | | | | | | | | | | | | | | Put all debugfs dependencies inside #ifdef CONFIG_DEBUG_FS. This includes some functions in allocators that were used only for debugging. Remove include of linux/debugfs.h on files that do not deal with debugfs. linux/debugfs.h implicitly included linux/fs.h, which we relied on. Add explicit include of linux/fs.h for all files where this is the case.

* gpu: nvgpu: Remove last Linux kmem usageAlex Waterman2017-04-04
| | | | | | | | | | | | | | | | | | Replace the last of the Linux kmem API usage with nvgpu kmem calls instead. Several places are left alone - allocating the struct gk20a in particular. Also one function was updated in the clk code to take a struct gk20a as an argument so that it could use nvgpu_kmalloc().

* gpu: nvgpu: Move allocators to common/mm/Alex Waterman2017-01-09
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().
