It seems to be a consequnce of the code from r222869. The test_tsc()
does not trust the P-state invariant report and explicitely check for
the family. Your CPU family is 0x14, while code only bumps TSC priority
for family 0x15+.
Currently, tsc_is_invariant is set when CPU reports AMDPM_TSC_INVARIANT,
or for some models. Should we bump TSC timecounter priority is smp
test passed and AMDPM_TSC_INVARIANT is set ?
For now, you could just set TSC as timecounter.
Thanks, changing to kern.timecounter.hardware=TSC also brings back
performance to where it was
