40  * This AGP memory type is required by some hardware like i810 video
41  * card, which need physical contiguous pages to setup hardware cursor.
42  * Usually, several tens of kilo bytes are needed in this case.
43  * We use DDI DMA interfaces to allocate such memory in agpgart driver,
44  * and it can not be exported to user applications directly by calling mmap
45  * on agpgart driver. The typical usage scenario is as the following:
46  * Firstly, Xserver get the memory physical address by calling AGPIOC_ALLOCATE
47  * on agpgart driver. Secondly, Xserver use the physical address to mmap
48  * the memory to Xserver space area by xsvc driver.
