Zusammenfassung
Dieser deutschsprachige technische Artikel von heise.de beschreibt die neuen AMD-Stromverwaltungsfunktionen, die in Linux Kernel 5.17 eingeführt wurden. Der Hauptfokus liegt auf dem neuen amd-pstate-Treiber, der "Collaborative Processor Performance Control" (CPPC) für AMD-Prozessoren implementiert und eine feiner abgestufte Stromverwaltung im Vergleich zum traditionellen ACPI-basierten Ansatz bietet.
Kernaussagen
- Linux Kernel 5.17 führt den amd-pstate-Treiber für AMD-Prozessoren ein
- CPPC (Collaborative Processor Performance Control) ist eine Hardware-Funktion, die präzisere Stromverwaltung ermöglicht
- Der vorherige acpi-cpufreq-Treiber verwendete nur 3 P-States (Performance States) für AMD-CPUs
- amd-pstate ersetzt P-States durch einen feiner abgestuften Mechanismus, der über die sysfs-Schnittstelle bereitgestellt wird
- Kernel-Governoren wie schedutil und ondemand können nun CPPC-Leistungsziele und Hinweise auswerten
- Dies ermöglicht eine feinere Stromverwaltung, reduziert den Energieverbrauch und verlängert die Akkulaufzeit auf mobilen Geräten
- amd-pstate erfordert AMD-Hardware mit CPPC-Unterstützung (neuere Generationen, plus einige Zen2- und Zen3-Modelle)
- Der Kernel wechselt automatisch zu acpi-cpufreq auf inkompatiblen Systemen
- Zusätzliche technische Details sind im Kernel Commit und in der Dokumentation unter
Documentation/admin-guide/pm/amd-pstate.rstverfügbar
