💖 zynqmp_ipi_mbox_get_buf_res(9) 💖

okay so this is a page from the Kernel API Manual, bestie — like, the actual kernel docs, and we're about to make it make sense. Sit down, hydrate, let's go 🫶

---

✨ NAME ✨

zynqmp_ipi_mbox_get_buf_res — literally just grabs a buffer resource out of the IPI dev node. that's the whole vibe ✨

---

🌸 SYNOPSIS 🌸

int zynqmp_ipi_mbox_get_buf_res (struct device_node *node , const char
*name , struct resource *res );

yes queen, it returns an int, and it takes three things. we'll get to those 💅

---

🎀 ARGUMENTS 🎀

• node — the IPI mbox device child node. like, the child node specifically, not the parent. don't play yourself 🙈
• name — the name of the IPI buffer. it's giving "which buffer tho" energy.
• res — a pointer to where the resource information is gonna be stored. you gotta hand it somewhere to put the goods 🍓

---

⭐ RETURN ⭐

• 0 for success — slay, we ate 💅
• negative value for failure — not the vibe, but that's how you'll know 😭
