Hello All,
What is the correct change in code/mindset needed to replace the
kiovec/kiobuf routines? I am currently using there routines to do a
scatter gather DMA from a user space buffer to/from a PCI video frame
buffer device. Should I approach this problem differently? The user
space buffer can be up to 8MB in size.
Thanks,
Jason

Direct use of get_user_pages() seems to be working OK for that sort of thing.
