[PATCH v2 00/21] Convert all remaining drivers to GEM object functions
The GEM and PRIME related callbacks in struct drm_driver are deprecated in
favor of GEM object functions in struct drm_gem_object_funcs. This patchset
converts the remaining drivers to object functions and removes most of the
obsolete interfaces.
Patches #1 to #16 and #18 to #19 convert DRM drivers to GEM object functions,
one by one. Each patch moves existing callbacks from struct drm_driver to

[PATCH v3 0/7] 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
