Add new unit common/gr/subctx.c to manage GR subcontext This unit provides interfaces to allocate/free/load GR subcontext Add new header file include/nvgpu/gr/subctx.h to declare all the interfaces. Right now channel_gk20a structure directly includes a nvgpu_mem for context header. Declare a new structure nvgpu_gr_subctx for subcontext and include this from channel_gk20a Make all necessary changes to refer ctx_header from subctx instead of directly referencing it from channel Jira NVGPU-1613 Change-Id: I9eb1ee8f26fa88d2881f9b294935b65e9cbcc9b4 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1990129 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
