Given the user-space virtual address of a page, is there a way to convert this into a physical address (ensuring that the page is swapped in, etc)?
I have a PCI bus master which can perform dma transfers and I want to set up the dma registers on the device to write directly to my user space [it is a a video capture card and I want to write directly to an X shared memory image]
Cheers, Ian
