Some chips can't use system memory as dma buffer(or vertex buffer),for pci card,it will use video memory as dma/vertex buffer. But drmAddBufs/drmMapBufs can't handle this case.
Created attachment 1127 [details] [review] The patch makes drmAddBufs/drmMapBufs can handle buffers in video memory The attached patch adds a new buffer type DRM_FB_BUFFER. It works like AGP memory but uses video memory.
I've commited this to the DRM CVS...
