Speaking of which, why is it some devices are not always present (same with systat -vmstat) eg on one machine v2% vmstat -i interrupt total rate stray irq7 2 0 hifn0 irq10 15680 0 fxp0 irq11 259067 2 mux irq15 378597 3 atkbd0 irq1 1 0 sio0 irq4 178 0 clk irq0 11466632 99 rtc irq8 14677398 127 Total 26797555 233 yet on another, offsite# vmstat -i interrupt total rate fxp0 irq11 29547828 61 mux irq15 453753 0 sio0 irq4 177 0 clk irq0 48204090 99 rtc irq8 61701185 127 Total 139907033 290 offsite#=20 offsite# dmesg | grep hifn hifn0 mem 0xe9802000-0xe9802fff,0xe9801000-0xe9801fff irq 10 at device 0.0 on pci1 hifn0: Hifn 7951, rev 0, 128KB sram, 193 sessions offsite#=20 How come the hifn does not show up ? I have noticed this with other devices as well ---Mike On Wed, 19 Nov 2003 09:46:02 +0100, in sentex.lists.freebsd.hackers you wrote: >ISTR there is a tool (other than systat -vmstat) that shows interrupt >statistics for all interrupts, but I can't find anything except the >hw.intrnames and hw.intrcnt sysctls, which aren't directly human- >readable.
