Dear all, I run CURRENT on a laptop with an AMD Carrizo (A12-8800B) which should have multiple boost states (Pb) according to the official specifications (see [1] and [2] pages 59 and 63). CURRENT fails to enumerate them and therefore only runs at base clock. A thread on freebsd-acpi [3] did unfortunately not help much, so I am hoping that the wider audience here may help? Thanks a lot for your time!
