| |
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
