Hardware PM State Control 默认为Disable 更改为Native mode。 保存BIOS配置,重启服务器,运行cpupower frequency-info检查,结果可以正常睿频到2.80G: analyzing CPU 0: driver: intel_pstate CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0...
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...

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 used under...

> 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 ...
2) If I enable Intel-pstate in grub and use the above method "b)" (Note: now "a)" cannot be used because there is no "userspace" governor when "scaling_driver" is "intel_pstate") to change cpu1's max frequency, the test program's run time changed signific...

I don't know the advantages and disadvantages of setting energy_performance_preference to balance_performance vs performance so I don't know if this is a good solution. Briefly looking through the kernel documentation for intel_pstate, their is nothing saying why when setting the scaling_governor...
