peter 96/12/02 17:23:44 Modified: i386/i386 pmap.c Log: Add optional SMP_INVLTLB code. Note that this appears to work, but I think it's not going to be the final form. I suspect that only a minority invltlb() and invltlb_1pg()/2pg() calls need to be propagated to all cpu's. (eg: only kernel mapping changes and changes for processes actually running on another cpu). Also, watching this on the serial trace shows that we do a hell of a lot of invltlb's... (peaking at several hundred per second from what I've seen, but this is a subjective estimate and not actually measured) Revision Changes Path 1.30 +34 -24 sys/i386/i386/pmap.c
