[PATCH 2/2] drm/ttm: Provide ttm_bo_global_{init/release}() for struct ttm_bo_global
So far, struct ttm_bo_global_ref was the only way of initializing a struct
ttm_bo_global. Providing separate initializer and release functions for
struct ttm_bo_global gives drivers the option of implementing their own
init and release callbacks for drm_global_references of type
DRM_GLOBAL_TTM_BO.
The original functions for i...

[PATCH 0/2][RESEND] Provide init/release functions for struct ttm_bo_global
TTM uses global memory and BO for backing graphics buffers. These are
represented by struct ttm_mem_global and struct ttm_bo_global.
Currently, struct ttm_bo_global can only be initialized and released through
struct ttm_bo_global_ref. This is a workaround for passing an instance of
ttm_mem_global to the BO global initialization code.
The use of struct ttm_bo_global_ref makes driver code unnecessary hard to
understand. At the...

[PATCH 1/2] drm/ttm: Rename ttm_bo_global_{init, release}() to ttm_bo_global_ref_{, }()
The functions ttm_bo_global_init() and ttm_bo_global_release() do not
receive an argument of type struct ttm_bo_global. Both take a struct
drm_global_reference that contains points to a struct ttm_bo_global_ref.
Renaming them reflects this.
