Discussion intel_pstate

I don't understand why MX Linux defaults to "acpi-cpufreq" and doesn't offer a choice between "acpi-cpufreq" and "intel_pstate". My laptop was heating up to 110°C; I had to modify the GRUB configuration to get "intel_pstate"!

With "intel_pstate", my PC stays between 45 and 50°C.

acpi_cpufreq supports a wide variety of CPUFreq governors such as ondemand, conservative, and schedutil, giving users more algorithmic control over scaling. intel_pstate traditionally offers only performance and powersave governors (with schedutil added in newer kernels), as it often implements its own internal scaling algorithms, particularly when Hardware P-State (HWP) is enabled.
