I was just given an HP machine that shows a little quirk in 'sysctl
hw.setperf':
hw.machine=amd64
hw.model=Pentium(R) Dual-Core CPU E5200 @ 2.50GHz
hw.ncpu=2
hw.byteorder=1234
hw.pagesize=4096
hw.disknames=sd0,cd0
hw.diskcount=2
hw.cpuspeed=2493
hw.setperf=99
hw.vendor=Hewlett-Packard
hw.product=HP Compaq dc7900 Ultra-Slim Desktop
hw.serialno=2UA9461120
hw.uuid=32ef50ee-e109-de11-bbda-5548b4800026
hw.physmem=1015681024
hw.usermem=1015603200
hw.ncpufound=2
None of my other machines have ever shown hw.setperf=99; they always boot
up at 100. It's not a problem, just a little quirk. The machine runs fine
and SpeedSteps properly with apmd. Running 'sysctl hw.setperf=100' bumps
up hw.cpuspeed to a displayed value of 2500. Has anyone seen this kind of
behavior before?
