problems getting AMD C-70 APU working with powerd/cpufreq

[tech-lists]

Hi,

I have a netbook with amd c-70 cpu and am trying to get powerd
to work with it. Will this chip not work with cpufreq/powerd?

system: FreeBSD 11.1-STABLE #0 r324342

# sysctl debug.cpufreq.verbose=1
debug.cpufreq.verbose: 0 -> 1
# kldload cpufreq
#
# powerd -vv
powerd: no cpufreq(4) support -- aborting: No such file or directory

# sysctl -a | grep cpu
