Why does some systems on RHEL8.5 showintel_cpufreqas scaling driver instead ofintel_pstatein the output ofcpupower frequency-info? When system is booted with RHEL8.4,intel_pstategets loaded, while when same system booted with RHEL8.5 kernel,intel_cpufreqdriver is seen to be loaded. Raw anal...

Root Cause cpupower frequency-inforeports the CPU frequency for theintel_pstateandacpi_cpufreqdrivers as provided by hardware to the kernel. Theintel_pstatedriver is able to report the turboboost frequency limit incpupoweras turboboost is a feature of the Intel CPU. The actual frequency being...
1 According to the above observations, why can Intel-pstate really change a cpu's frequency but other cpufreq drivers cannot (by "really", I mean the changing effect should be observed by running a test program)? 2 With turbo boost enabled, is each core's frequenc...
这是Intel 近几代 CPU 独享的 moment,内核开启 intel pstate 后(V23 内核默认开启)你会发现在 policy<x>文件夹下多了几个文件: 我们只需要关注: energy_performance_available_perference : 可用的 pstate 电源调度 energy_performance_perference : 当前选定的 pstate 电源调度,可以更改此文件内容来更改电源调度...

> IMHO, this patch fix this bug in kernel 6.10.11-1. the patch I created was applied upstream now (https://git.kernel.org/linus/8b4865cd904650cbed7f2407e653934c621b8127) and will be part of 6.12-rc2. Is it worth backporting this patch to bookworm (assuming 6.1 is ...
