[PATCH libdrm] drm: Remove create_handle() drm_framebuffer "virtual".
Because all drivers currently use gem objects for framebuffer planes,
the virtual create_handle() is not required. This change adds a
struct drm_gem_object *gems[4] field to drm_framebuffer and removes
create_handle() function pointer from drm_framebuffer_funcs. The
corresponding *_create_handle() function is removed from each driver.
In many cases this change eliminates a struct *_framebuffer object,
as the only need for the derived struct is th...

[PATCH v2 06/21] drm/i915: Introduce GEM object functions
GEM object functions deprecate several similar callback interfaces in
struct drm_driver. This patch replaces the per-driver callbacks with
per-instance callbacks in i915.
v2:
* move object-function instance to i915_gem_object.c (Jani)

[PATCH v6 00/10] Support GEM object mappings from I/O memory
DRM's fbdev console uses regular load and store operations to update
framebuffer memory. The bochs driver on sparc64 requires the use of
I/O-specific load and store operations. We have a workaround, but need
a long-term solution to the problem.
This patchset changes GEM's vmap/vunmap interfaces to forward pointers
of type struct dma_buf_map and updates the generic fbdev emulation to
use
