ti_sci_inta_xlate_irq(9)

💅 ti_sci_inta_xlate_irq(9) — from the Kernel API Manual, bestie 🎀

okay so picture this: you're deep in the kernel, you've got a hardware irq number, and you need to know what its parent is speaking. that's the whole vibe of ti_sci_inta_xlate_irq. it's the translator girlie of the irqchip world ✨

---

🌸 NAME 🌸

ti_sci_inta_xlate_irq — literally just translates a hwirq into its parent's hwirq 🦋

---

⭐ SYNOPSIS ⭐

int ti_sci_inta_xlate_irq (struct ti_sci_inta_irq_domain *inta , u16
vint_id );

---

🫶 ARGUMENTS 🫶

• inta — the IRQ domain that corresponds to the Interrupt Aggregator. she's the main character here 👑
• vint_id — the hardware irq that corresponds to that irq domain up there. the little number you're trying to place 💫

---

🔥 DESCRIPTION 🔥

so like, it returns the parent irq number if the translation is available — and if it's not? bestie, you get -ENOENT. no translation, no irq, periodt 💀

ngl this one's short but she ate. call it, get a parent irq or get -ENOENT, that's the whole story 🙈
