I'd like to develop a kernel module for FreeBSD, able to read & write directly to VGA text-mode screen buffer. I know that this buffer is located at 0xB8000 in physical address space. But in kernel I must address it using kernel virtual address space.
Thus, the question is: how can I _correctly_ convert physical address into kernel virtual address? Now I use the following trick: 0xC0000000 + 0xB8000, but I want to use more correct method. :) thanks.
