Hello All,
We're working on a driver for a PCI card, we're currently running into a
problem that's symptomatic of a cache coherency problem. We have a area of
memory that we manipulate and pass a physical address to our card. In other
OS's (Linux, NT), before we manipulate this memory area, we mark the area as
non-cachable. Are there similar operations/system calls we can use in
FreeBSD? Are there any FAQ's, Docs or man-pages that explain memory
usage/attributes?
Thanks very much!
Chris
