The Linux AGP driver has the same code. It appears to be forcing a read of the TLB registers to force prior writes to clear the TLB entries to flush perhaps? I'm not sure why you are getting a panic. What kind of fault did you get? (The original kernel panic messages would be needed.) -- John Baldwin _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
