...mc can use these helpers. Future directions: with these changes, the respective drivers can also share some of their mode-setting or fbdev code. GEM VRAM could implement PRIME helpers, which would allow for using the generic fbcon. The patch set is against a recent drm-tip. v2: * rename |struct drm_gem_ttm_object| to |struct drm_gem_vram_object| * rename |struct drm_simple_ttm| to |struct drm_vram_mm| * make drm_is_gem_ttm() an internal helper * add drm_gem_vram_kmap_at() * return is_iomem from kmap functions * redefine TTM placement flags for public interface * add drm_vram_mm_mmap() helper * replac...
