Nate,

Thanks for the hard work on cpufreq!  I am running an AMD64 3400 CPU in
my lappy, and I don't see any difference in dev.cpu with cpufreq and/or
acpi_perf loaded.  This is all I have:

dev.cpu.0.%desc: ACPI CPU (2 Cx states)
dev.cpu.0.%driver: cpu
dev.cpu.0.%location: handle=\_PR_.CPU0
dev.cpu.0.%pnpinfo: _HID=none _UID=0
dev.cpu.0.%parent: acpi0

The above is the same for the following conditions:

 o cpufreq AND acpi_perf NOT loaded
 o cpufreq (without acpi_perf) loaded
 o acpi_perf (without cpufreq) loaded
 o cpufreq AND acpi_perf loaded

The acpi_ppc module does continue to work for me, however, yielding the
following additional OIDs from hw.acpi:

----------8<--------------
# sysctl hw.acpi.cpu
hw.acpi.cpu.cx_supported: C1/0 C2/80
hw.acpi.cpu.cx_lowest: C2
hw.acpi.cpu.cx_usage: 2.36% 97.63%

# kldload acpi_ppc

# sysctl hw.acpi.cpu
hw.acpi.cpu.cx_supported: C1/0 C2/80
hw.acpi.cpu.cx_lowest: C2
hw.acpi.cpu.cx_usage: 2.32% 97.67%
hw.acpi.cpu.px_control: -1
hw.acpi.cpu.px_highest: 0
hw.acpi.cpu.px_lowest: 2
hw.acpi.cpu.px_current: 2
hw.acpi.cpu.px_supported: 2200 1800 800
hw.acpi.cpu.px_usage: 3.33% 3.33% 93.33%
----------8<--------------

All the stuff you would normally ask for can be found here:

Also, I had to build the cpufreq and acpi_perf modules manually, as they
weren't built automatically.  Maybe they aren't "connected" to the build
for AMD64?

Thanks again, great work!
