WebIncluded below are historic documents describing assorted CPU performance scaling drivers. They are reproduced verbatim, with the original white space formatting and indentation preserved, except for the added leading space character in every line of text. AMD PowerNow! Drivers WebIntroduction. amd-pstate is the AMD CPU performance scaling driver that introduces a new CPU frequency control mechanism on modern AMD APU and CPU series in Linux kernel. The new mechanism is based on Collaborative Processor Performance Control (CPPC) which provides finer grain frequency management than legacy ACPI hardware P-States.

WebFeb 20, 2024 · So in RHEL-7, the available CPU governors on Intel CPUs > will depend on CPU model. More precisely, it depends on the scaling driver that is used (/sys/devices/system/cpu/cpu*/cpufreq/scaling_driver). With the intel_pstate driver you get the powersave and performance driver. WebNext, the scaling driver’s ->init() callback is invoked with the policy pointer of the new CPU passed to it as the argument. That callback is expected to initialize the performance scaling hardware interface for the given CPU (or, more precisely, for the set of CPUs sharing the hardware interface it belongs to, represented by its policy ... littelfuse class t fuse
