💅 ni_tio_set_bits(9) 💅

okay so bestie, welcome to the Kernel API Manual entry for ni_tio_set_bits — yes the (9) means it's a kernel function, we're in the big leagues now 🎀

---

✨ NAME ✨

ni_tio_set_bits — write a counter register safely. like, no cap, safely. that's the whole vibe 🔥

---

🌸 SYNOPSIS 🌸

void ni_tio_set_bits (struct ni_gpct *counter , enum ni_gpct_register
reg , unsigned int mask , unsigned int value );

look at that signature, it's giving very proper kernel function 💜 copy it exactly, don't freestyle it, i'm begging 🫶

---

🦋 ARGUMENTS 🦋

• counter — a struct ni_gpct counter. that's your little guy, your main character 💫
• reg — the register you wanna write to. choose wisely ✨
• mask — the bits you're changing. literally just the bits, bestie 🎯
• value — the new value for those bits. the new era, the glow-up 🌈

---

💖 DESCRIPTION 💖

so here's the tea ☕ — you use this to write to a register, and update the software copy of it.

but like, why do you need a special function for that? because the register's bits might get twiddled in interrupt context 😭 or the software copy might be read in interrupt context. so this is the safe little wrapper so nothing goes sideways. highkey important, ngl 👑

bestie this is exactly the kind of thing where you don't wanna be clever and hand-roll it. interrupt context does not care about your feelings 💀
