Ah, that's so lovely, thanks Jung-uk; I feel that our support for AMD
fam. 15h CPUs is lacking.  E.g. only four P-states are reported for my
A8-5550M, while it supports boosted P-states per BKDG, and reading MSRs
directly via `sysutils/amdmsrtweaker' reports eight of them (P0 .. P7),
with three turbo P-states P0 P1 P2.

Since you have A10-6800 you might try to reproduce what I see here with
A8-5550M.
