Subject: thinking about graphics programming Date: Tue, 14 Jan 1992 19:36:45 EST From: "Derek Lieber" <derek@watson.ibm.com>
With all this talk about X servers and such, I was thinking about
writing some graphics programs which would be able to do their work
outside the kernel, by accessing video memory directly. Does linux
let one establish a mapping between a region of a process's virtual
address space and a region of physical memory (I'm thinking of
something like the shmxxx" family of system calls for dealing with
shared memory)?
