💖 alchemy_gpio2_enable_int(9) — the kernel API manual, bestie edition 🎀

okay so you found the alchemy_gpio2_enable_int(9) page in the Kernel API Manual — congrats, this one's a ✨macro✨ and it's lowkey iconic once you get the vibe. sit down, grab a strawberry drink 🍓, and let's get into it.

✨ NAME ✨

alchemy_gpio2_enable_int — turn on a GPIO2 pin's contribution to the shared irq. that's it, that's the whole thing, but the details are where it gets juicy 💅

---

🌸 SYNOPSIS 🌸

void alchemy_gpio2_enable_int (int gpio2 );

---

🦋 ARGUMENTS 🦋

• gpio2 — the GPIO2 pin you wanna activate, fr fr. valid range is 200...215 💖

---

👑 DESCRIPTION 👑

okay so here's the lore 🫶: GPIO208-215 all share one interrupt line going to the INTC. they get and'ed with a per-pin enable bit, and then finally or'ed together to make a single irq request — which is genuinely so useful for active-high sources, no cap ⭐

with this function you can enable a pin's individual contribution to that int request. cute, right? BUT — and this is the main character energy part — like all other GPIO-based interrupts, the INTC also has to be programmed to accept the GPIO208_215 interrupt. it's a two-party situation, you can't just show up alone 🙈

---

💀 NOTE 💀

• calling this macro is only necessary for GPIO208-215. every other GPIO2-based interrupt has its own request to the INTC, so they don't need this 💜
• please, please consult your Alchemy databook for more information! it's giving required reading 📚
• on the Au1550, GPIOs 201-205 also have a shared interrupt request line to the INTC, GPIO201_205. this function works for those too — slay 🎀
• (200-215 by default). no sanity checks are made, — so yeah, it will not vibe check your input for you. you're on your own there 😭🔥

bestie warning: no sanity checks means no sanity checks. bad input does not get caught. periodt.
