This provides control over the caching of memory, which makes write-combined IO possible. Graphics drivers can use this to transfer data at a much higher rate to the video memory. The implementation is a bit hacky but it'll do for now. It provides enough support for the experimental VBE driver to work on the real computers I tested it on, even if the BIOS uses screwed up default MTRRs. The virtual memory layer now automatically uses the PAT feature if available but in a backwards compatible manner and otherwise just tries to approximate PAT features if they are asked for. |
