cm_control(9)

💅 cm_control(9)

okay so this is a page straight out of the Kernel API Manual, and it's literally the tiniest little function ever, but she's iconic so let's talk about her 🎀

---

✨ NAME ✨

cm_control — the girl whose whole job is updating the CM_CTRL register. that's it. that's the gig. 💅

---

🌸 SYNOPSIS 🌸

void cm_control (u32 mask , u32 set );

returns void, meaning she gives you nothing back — no return value, no little gift, no nothing. she just does the thing and dips 🦋

---

🎀 ARGUMENTS 🎀

• mask — the bits you wanna change, bestie. this is your little selection of which bits are even invited to the party 💖
• set — the bits you actually wanna set. the chosen ones. the main characters 👑

so like, mask says "these are the ones we're touching" and set says "and here's what they become" — two besties working together fr fr 🫶
