+## 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](https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c22760885fd6) und in der Dokumentation unter `Documentation/admin-guide/pm/amd-pstate.rst` verfügbar
