AMD Core Performance Boost For Linux Getting Per-CPU Core Controls
For the past several months AMD Linux engineers have been working on AMD Core Performance Boost support for their P-State CPU frequency scaling driver
These patches have been for handling Core Performance Boost within the AMD P-State driver and also the ability to toggle the feature via the/sys/devices/system/cpu/amd_pstate/cpb_boost interface.
