I'm trying to do some debugging related to interrupts, and I thought I would try getting the interrupt counts (I'm especially interested in knowing what Schizo thinks.) So I thought I would try vmstat -i.
On my two systems, the only devices which are reported by vmstat -i are a) the system clock, b) the audio chips, and c) the floppy controller. This is almost completely useless. Reading vmstat.c, it appears that all that is needed is for the various drivers/devices to export kstat interrupts. Is there any chance of getting this added to Solaris? Even if we started with the top level (I'd start with hard cpu interrupts, and work my way down to nexus drivers, etc.) it would be incredibly useful in debugging certain kinds of problems. I'd be willing to modify my own afe driver to export interrupt kstats as well, but again, nexus driver interrupts are much more interesting to me at the moment. -- Garrett D'Amore, Principal Software Engineer Tadpole Computer / Computing Technologies Division, General Dynamics C4 Systems http://www.tadpolecomputer.com/ Phone: 951 325-2134 Fax: 951 325-2191 _______________________________________________ opensolaris-code mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/opensolaris-code
