DRM client buffers are permanently mapped throughout their lifetime. This prevents us from using generic framebuffer emulation for devices with small dedicated video memory, such as ast or mgag200. With fb buffers permanently mapped, such devices often won't have enougth space left to display other content (e.g., X11). This patch set introduces unmappable DRM client buffers for framebuffer

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
