    Phoronix: AMD Posts P-State EPP v9 Driver That Aims To Be Ready For Linux 6.3

    While the Linux 6.2 kernel merge window just wrapped up, AMD's P-State EPP driver was deemed not ready for making it this cycle. However, with AMD having now iterated it to a ninth revision, it's looking like this P-State "Energy Performance Preference" functionality over the existing P-State driver support will be ready for merging come Linux 6.3...

        Some of the recent P-state changes removed the need to use additional boot command-line parameters (such as amd_pstate=legacy_cppc and amd_pstate.replace=1), so now simply using amd-pstate=active is enough to enable it, even with CPUs that don't have full MSR support (like desktop Zen 3 CPUs)!

          Let's hope this one will finally make it, and no intel people will block it. It might be a reasoned rejection but as we say here it does have a "Gschm├Ąckle" (a certain subtle by-taste/flavor/overtone) once an engineer from a competing enterprise rejects a patch from the other company.
          Otherwise 6.2. is already a release to look forward to.
          Stop TCPA, stupid software patents and corrupt politicians!

            Did this make it into 6.3-rc1?
