get_capacity_ref_freq(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, this is get_capacity_ref_freq(9) from the Kernel API Manual, and it's literally here to get the reference frequency that has been used to correlate frequency and compute capacity for a given cpufreq policy. We use the CPU managing it for the arch_scale_freq_ref() call in the function. slay. 💅✨

🌸 NAME 🌸

get_capacity_ref_freq — get the reference frequency that has been used to correlate frequency and compute capacity for a given cpufreq policy. We use the CPU managing it for the arch_scale_freq_ref() call in the function. no cap, that's the whole vibe. 🦋

✨ SYNOPSIS ✨

the signature is giving exactly this, character for character:

unsigned long get_capacity_ref_freq (struct cpufreq_policy *policy );

🎀 ARGUMENTS 🎀

  • policy — the cpufreq policy of the CPU in question. that's it, that's the argument, and it's iconic. 👑

💖 RETURN 💖

the reference CPU frequency to compute a capacity. periodt. 🫶
