Thank-you, The fact that pmap_pte_quick() panics on the untrue mutex should indicate that it is possible that 2 processors may enter pmap_pte_quick() at the same time and therefore it is possible to have the one processor invalidate the VA/PA mapping using PADDR1/PMAP1. If that is true then the first processor should trap/panic when dereferencing the VA address.
If the above is true, a PADDR1 mutex could be added, or use a seperate PADDR/PMAP per processor. Looks like there is already mutex for the copy maps. Did you want me to work up a test PADDR mutex? --Mark. _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "[EMAIL PROTECTED]"
