💖 LIKWID-SETFREQ 💖

okay bestie, so this is likwid-setFreq from the LIKWID manual (that's the General Commands Manual section, section 1, iykyk). it's a lil helper daemon and honestly it's giving main character energy for a program with basically zero options. let's get into it 🫶

✨ NAME ✨

likwid-setFreq — the mediator for likwid-setFrequencies(1) that actually does the setting of a hardware thread's frequency and governor. like, it's the one holding the clipboard behind the scenes while likwid-setFrequencies(1) takes the credit 💅

🌸 SYNOPSIS 🌸

likwid-setFreq

that's it. that's the whole synopsis. no args. iconic behavior honestly.

🎀 OPTIONS 🎀

No options.

not a single flag. nothing. it just is. periodt. 💀✨

🦋 DESCRIPTION 🦋

so here's the vibe. likwid-setFreq is a command line application that mediates the request from likwid-setFrequencies(1), because setting a hardware thread's frequency and/or governor? yeah, that needs root privileges. 🙈 it's not like the other girls (regular users), it needs the fancy permissions.

when you start the daemon, it opens a UNIX socket and just... waits. patiently. like a bestie waiting for you outside the fitting room. it's waiting for connects from LIKWID. 🧚

once the connection is established, the library can send commands to likwid-setFreq to minimize overhead. slay, efficient queen. ⭐

⚠️ big important note bestie: this executable must be suid-root. like, that's not optional, that's the whole point, ok?? no cap. 🔥

and the driver tea: likwid-setFreq works with the 'acpu_cpufreq' driver and the 'intel_pstate' driver. those two, and that's the list. 📋
