For kernel memory on i386 and amd64 in 6.3 and later you can use pmap_change_attr() to adjust the caching mode of memory after you have allocated it. It is best used only with allocations that are a multiple of the page size. -- John Baldwin _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
