aio_chip_init(9)

💖 aio_chip_init(9) — the "let's get this AIO party started" function

okay so real quick, the vibe check: this is a Kernel API Manual page, section 9, and the star of the show is aio_chip_init. Yes bestie, we're in kernel-land. Buckle up 🎀

✨ NAME ✨

aio_chip_init — initialize AIO whole settings

---

🌸 SYNOPSIS 🌸

void aio_chip_init (struct uniphier_aio_chip *chip );

---

🦋 ARGUMENTS 🦋

• chip — the AIO chip pointer. that's it, that's the whole argument list, she's low maintenance 💅

---

⭐ DESCRIPTION ⭐

so basically this function sets the AIO fixed settings and the whole device settings onto AIO. Like, all of them. The whole vibe. 🫶

The way this works: you need to call this function once at driver startup. Not twice. Not whenever you feel like it. Once. At startup. Periodt.

Here's the part where I hold your hand, bestie, because it sounds scary: the register area that gets changed by this function is shared by all modules of AIO. Shared! By everyone! But 😌 there is no race condition, because this function has always set the exact same initialize values. Every single time. Same values, no cap. So even though everybody's touching the same registers, nobody's ever writing anything different. It's giving "we all agree on the same group-chat pinned message" energy ✨
