I am looking for the most current (blessed) structure for mapping PCI memory to a user process. One that allows both PIO and busmastering to work on a common block of PCI RAM. I am not concerned with backporting to older kernels but it would be nice if the solution wasn't ibm specific.
My problem is a 64M window into a frame buffer that I would like to map into user space. I am more than willing to put forth the effort, I just want to make sure I'm heading in the right direction.
Is there a better forum for posting this? Regards, J. Deas
RH9.0 2.4.20-6smp kernel and above.
