Several simple framebuffer drivers copy most of the TTM code from each other. The implementation is always the same; except for the name of some data structures. As recently discussed, this patch set provides generic memory-management code for simple framebuffers with dedicated video memory. It further converts the respective drivers to the generic code. The shared code is basically the same

VRAM MM and GEM VRAM are only used with each other. This patch set moves VRAM MM into GEM VRAM source files and cleans up the helper's public interface. Thomas Zimmermann (4): drm/vram: Move VRAM memory manager to GEM VRAM implementation drm/vram: Have VRAM MM call GEM VRAM functions directly drm/vram: Unexport internal functions of VRAM MM drm/vram: Unconditonally set BO call-back

VRAM MM and GEM VRAM are only used with each other. This patch set moves VRAM MM into GEM VRAM source files and cleans up the helper's public interface. Version 2 of the patch set doesn't contain functional changes. I'm reposting due to the rebasing onto the debugfs patches. v2: * updated for debugfs support * fixed typos in comments Thomas Zimmermann (4): drm/vram: Move VRAM
