SubjectPCI bus mastering in userland
Hi folks,
I am programming a driver for a evaluation board from AMCC.
The kernel module is OK, with or without bus mastering and irq support.
But one of my great concerns is to offer a user-mode driver, too;
FIFO programming is quite easy, and what about bus mastering transfers in
user-mode ?
I need a buffer in user-mode which is:
1) not swappable -- a physical memory
2) i need to convert this a physical address to write on the proper
register of my board (which knows only phys memory, i suppose)

thanks in advance
