The patch set replaces code in hibmc with generic implementation. Version 3 of the patchset only adds fixes. I'm reposting the whole thing for possible testers.
Patches 1 to 4 replace fbdev emuation, framebuffer and creation of dumb buffers with respective code from DRM helpers. Patch 5 adds an additional interface to debugfs that displays the allocated and free areas in video memory.
The patches have only been compile-tested. Further testing is appreciated.
v3: * only do power-of-2 test if pitch_align is given * update mgag200 for changes to drm_gem_vram_fill_create_dumb() v2: * split [3/4] into vram and hibmc changes * verify that pitch_align is power of two
