Hello. This is related to master. I have AMD FX-4170 CPU with 6 P-states.
For some reason, DragonFlyBSD can work with maximum of 5 for some CPUs.

See
http://gitweb.dragonflybsd.org/dragonfly.git/blob/HEAD:/sys/platform/pc64/acpica/acpi_pstate_machdep.c

I get a message "cpu3: only P0-P4 is allowed" and there are no frequency
related sysctls in hw.acpi.cpu

I suggest an attached patch, which works for me. Further testing requested.

wbr, Vasily.
