marcel 2007-07-30 22:52:52 UTC FreeBSD src repository Modified files: sys/ia64/ia64 exception.S Log: o Switch to physical addressing before dereferencing the VHPT bucket pointer. The virtual mapping may not be present in the translation cache. This will result in a nested TLB fault at a place we don't handle (and don't want to handle). o Make sure there's a stop after the rfi instruction, otherwise its behaviour is undefined. o Make sure we switch back to virtual addressing before doing a rfi. Behaviour is undefined otherwise. Approved by: re (blanket) Revision Changes Path 1.61 +62 -37 src/sys/ia64/ia64/exception.S
