ti_sci_intr_xlate_irq(9)

💅 ti_sci_intr_xlate_irq 💅

okay so bestie, welcome to the Kernel API Manual ✨ — today's main character is ti_sci_intr_xlate_irq(9), and she is literally here to translate hardware IRQs into her parent's IRQ number. no cap, that's the whole gig 🎀

---

🌸 NAME 🌸

ti_sci_intr_xlate_irq — translate hwirq to parent's hwirq 🦋

like… she takes a hwirq and tells you what it is in parent-speak. it's giving translator app but for interrupts 💅

---

✨ SYNOPSIS ✨

int ti_sci_intr_xlate_irq (struct ti_sci_intr_irq_domain *intr , u32 irq );

yup, that's the whole signature. two args, one int coming back at you 🫶

---

🎀 ARGUMENTS 🎀

• intr — the IRQ domain corresponding to the Interrupt Router 👑 like, this is the domain you're translating out of, bestie, so don't hand her a random one or it's gonna be a whole thing 😭
• irq — the hardware irq corresponding to the above irq domain 🌈 (yes, the above one — they're a matched set, iykyk)

---

💖 DESCRIPTION 💖

so here's the tea ☕: this function returns the parent irq number if a translation is available. that's it, that's the slay ✨

but if the translation isn't available? she returns -ENOENT 💀 no parent irq for you, bestie. not found, not today, go home 🙈

quick vibe check: the return value is either the parent irq number (a real, usable number, iconic) or -ENOENT (the "nope, no translation available" answer). those are your two outcomes — don't go inventing a third one 🧚
