Nvgpu submit path has a lot of dependency on Linux framework e.g. use of copy_from_user, use of structures defined in uapi/nvgpu headers, dma_buf_* calls for trace support etc Hence to keep common code independent of Linux code, move submit path to Linux directory Move below APIs to common/linux/channel.c trace_write_pushbuffer() trace_write_pushbuffer_range() gk20a_submit_prepare_syncs() gk20a_submit_append_priv_cmdbuf() gk20a_submit_append_gpfifo() gk20a_submit_channel_gpfifo() Move below APIs to common/linux/ce2.c gk20a_ce_execute_ops() Define gk20a_ce_execute_ops() in common/linux/ce2.c, and declare it in gk20a/ce2_gk20a.h since it is needed in common/mm code too Each OS needs to implement this API separately gk20a_channel_alloc_gpfifo() use sizeof(nvgpu_gpfifo) to get size of one gpfifo entry, but structure nvgpu_gpfifo is linux specific Define new nvgpu_get_gpfifo_entry_size() in linux specific code and use it in gk20a_channel_alloc_gpfifo() to get gpfifo entry size Each OS needs to implement this API separately Export some APIs from gk20a/ce2_gk20a.h and gk20a/channel_gk20a.h that are needed in linux code Jira NVGPU-259 Jira NVGPU-313 Change-Id: I360c6cb8ce4494b1e50c66af334a2a379f0d2dc4 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1586277 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
