System is unusably slow. Plugged in, CPU correctly bursts to 3.2GHz+. Scaling driver: amd-pstate-epp (active mode) Scaling max freq: identical plugged and unplugged (5134889) Boost: enabled (returns 1) EPP: balance_performance / performance override makes no difference Tested/confirmed not the cause: - amd_pstate=3Dactive / guided / passive =E2=80=94 all throttle same - EPP forced to performance =E2=80=94 no effect - powerprofilesctl set balanced/performance =E2=80=94 no effect=20=20 - ryzenadj STAPM/PPT override =E2=80=94 no effect - amd_pmf.disable=3D1 =E2=80=94 no effect - dytc_lapmode =3D 0 (lap mode not triggered) Key dmesg evidence: amd-pmf AMDI0102:00: PMF Smart PC not advertised in BIOS!:-22 ACPI: [Firmware Bug]: BIOS _OSI(Linux) query ignored Suspicion: Firmware is applying a hard STAPM/TDP cap on battery that cannot be overridden through any Linux power management interface. The amd-pmf driver initializes in degraded mode due to Smart PC not being advertised, possibly falling back to aggressive power limiting behavior. --=20 You may reply to this email to add a comment.
