I'm working on a DRI implementation for a graphic chip, which has PCI DMA capability 
but without any GART functions.  In its implementation, I tried to get DMA buffers, 
but it just required to flush memory cache before starting DMA.  Is it supposed to 
work that way, or have I missed something?

I used drmAddBufs with flags == 0.

As I'm a newbie DRI developoer, any help is welcome.  Thanks in advance.
