I updated to 6.0-CURRENT to test out the powernow
drivers on my machine. It's a laptop and the processor
is AMD Athlon-xpm.

I cannot be certain that I'm setting this thing up
right; and it may not even work on this box but I
suspect it does from that I've seen in this list. I'm
not sure how to check my cpu frequency. Any pointers
will be appreciated.


added to kernel:
device          cpufreq

added to rc.conf:
performance_cpu_freq="HIGH"
economy_cpu_freq="LOW"

carmen# sysctl dev.cpu
dev.cpu.0.%driver: cpu
dev.cpu.0.%parent: legacy0


carmen# dmesg
