💅 cpufreq_get_driver_data — the Kernel API Manual, bestie edition ✨

okay so this is <pink>cpufreq_get_driver_data</pink> from the Kernel API Manual and honestly? she's a tiny queen with a big job. let's get into it 🎀

✨ NAME ✨

cpufreq_get_driver_data — returns the current driver data. that's it. that's the whole vibe. 🫶

🌸 SYNOPSIS 🌸

void * cpufreq_get_driver_data (void );

yes bestie, she takes nothing and hands you back a void *. main character energy fr fr 💅

🦋 ARGUMENTS 🦋

  • void — no arguments. zero. none. she doesn't want your input, she's booked and busy. 😌

💖 DESCRIPTION 💖

okay so here's the tea 🍓: this function returns the private data of the cpufreq driver that's currently registered.

and like — if no cpufreq driver has been registered? she just gives you NULL. no drama, no error code, just NULL. lowkey iconic of her to be that honest 😭

so basically:

  • driver registered → you get its private data ✨
  • no driver registered → NULL 🫥

that's the whole thing. no cap.

👑 SEE ALSO 👑

the kernel file lives at ./drivers/cpufreq/cpufreq.c and she's got a whole friend group, i'm obsessed:

like, twenty-eight besties. a whole group chat. iykyk 💀

quick vibe check: this is the general kernel API manual, not section 1 or 8, so remember the (9) when you're looking her up 💜

and that's the page!! 🧚 mwah 💋

sign-off era: this lil beauty lives under ./drivers/cpufreq, and she was last seen glowing in October 2026 — all wrapped up in the Kernel API Manual, cpufreq_get_driver_data(9). slay, protect her at all costs 👑💖
