✨ logic_pio_to_hwaddr(9) ✨

okay so this is a page from the Kernel API Manual (yes bestie, the whole manual, we're in it) and it's literally about translating a logical PIO into a hardware address 💅

---

🎀 NAME 🎀

logic_pio_to_hwaddr — translate logical PIO to HW address

---

🌸 SYNOPSIS 🌸

resource_size_t logic_pio_to_hwaddr (unsigned long pio );

---

🦋 ARGUMENTS 🦋

• pio — the logical PIO value, like, the one you're trying to convert 🫶

---

💖 DESCRIPTION 💖

So here's the tea: it returns the HW address if it's valid, and ~0 otherwise. That's it, that's the whole mood 😭

It translates the input logical PIO into the corresponding hardware address — glow-up for your integer, honestly ✨

One thing though, and this is important bestie: the input PIO should be unique in the whole logical PIO space. Whole. Entire. Global. No duplicates, no cap 🙈 It's giving "one of a kind" main character energy and honestly respect 👑
