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>
