| | | | | | | | | | | | | Conditionally compile debug_kmem.c in the Makefile since the entire file is not needed when CONFIG_NVGPU_TRACK_KMEM_USAGE is not enabled. Removing as many conditional compilation flags from the C code itself is highly desirable from a code complexity standard.

* gpu: nvgpu: Add nvgpu/errno.hAlex Waterman2017-10-10
| | | | | | | | | | | | | | | | Add an <nvgpu/errno.h> header file to explicitly include the -E* error messages. Useful for header files with static inlines that return error messages. In actual C code normally enough Linux/QNX headers bleed in to get the error messages but header files with sparse includes do not have this luxury.

| | | | | | | | | | | | | | | | | | | | __nvgpu_gmmu_do_update_page_table() uses nvgpu_sgt_for_each_sgl to loop through the entries of a buffer to be mapped, so when continue is used, the sgl entry must not be reassigned again like it was before with a pure while-and-update loop. Delete a reassignment to fix a case where sgl = sgl->next could happen twice.

* gpu: nvgpu: Combine VIDMEM and SYSMEM map pathsAlex Waterman2017-10-04
| | | | | | | | | | | | | | | | | | | | | | | | Combine the VIDMEM and SYSMEM GMMU mapping paths into one single function. With the proper nvgpu_sgt abstraction in place the high level mapping code can treat these two types of maps identically. The benefits of this are immediate: a change to the mapping code will have much more testing coverage - the same code runs on both vidmem and sysmem. This also makes it easier to make changes to mapping code since the changes will be testable no matter what type of mem is being mapped.
