sourced | Linux-Kerneltreiber für das Power Management von AMD-Prozessoren über die CPPC-Schnittstelle; löst acpi-cpufreq ab. |
amd-pstate
Typ: technology
Beschreibung
amd-pstate ist ein Linux-Kerneltreiber, der in Version 5.17 eingeführt wurde und Energieverwaltung für AMD-Prozessoren mithilfe der CPPC-Schnittstelle (Collaborative Processor Performance Control) bietet. Er ersetzt den älteren ACPI-basierten Ansatz mit einem feingranularerem und effizienteren Mechanismus zur Steuerung von CPU-Leistung und Stromverbrauch.
Kerndaten
- Zweck: CPU-Energieverwaltung für AMD-Prozessoren
- Status: Aktiv (eingeführt in Linux 5.17)
- Typ: Kerneltreiber
- Schnittstelle: sysfs
- Hardware-Anforderung: AMD-CPUs mit CPPC-Unterstützung (neuere Generationen, sowie einige Zen2- und Zen3-Modelle)
- Kernel-Commit: c22760885fd6
- Dokumentation: Documentation/admin-guide/pm/amd-pstate.rst
Beziehungen
5.17+
- Implementiert: CPPC (Collaborative Processor Performance Control) für AMD-CPUs auf unterstützter Hardware (schedutil, ondemand) auf inkompatiblen Systemen
- Verglichen in: amd-pstate vs acpi-cpufreq
Details
Funktionen
- Feinere Granularität: Bietet präzisere Kontrolle über CPU-Leistungszustände im Vergleich zu den 3 P-States, die acpi-cpufreq anbietet
- Hardware-Hinweise: CPPC-Hardware bietet Leistungsziele und Hinweise, die Governor auswerten können
- Dynamische Regulierung: Ermöglicht feingranulare Systemregulation basierend auf Workload und Stromanforderungen
- Energieeffizienz: Reduziert Stromverbrauch, besonders vorteilhaft für mobile Geräte, wo es die Akkulaufzeit verlängert
Kompatibilität
- Unterstützte Hardware: Neuere AMD-CPU-Generationen, sowie einige Zen2- und Zen3-Modelle
- Fallback-Mechanismus: Wenn amd-pstate nicht initialisiert werden kann oder auf inkompatible Hardware läuft, fällt der Kernel automatisch auf acpi-cpufreq zurück
- Governor-Unterstützung: Funktioniert mit vorhandenen Kernel-Governoren wie schedutil und ondemand
Verwendung
Der Treiber stellt seine Konfiguration und Status über die sysfs-Schnittstelle bereit und ermöglicht:
- Anzeigen von aktuellen Leistungszuständen
- Anpassung von Energieverwaltungsparametern
- Überwachung von CPPC-bezogenen Metriken
Historie
- 2022-03-20: Eingeführt in Linux Kernel 5.17
- 2022: Initiale Bereitstellung auf AMD Zen2- und Zen3-Prozessoren
