💖 ti_sci_inta_alloc_irq(9) 💖

okay so bestie, welcome to the Kernel API Manual entry for ti_sci_inta_alloc_irq(9) — yes the whole page is literally named after the function, iconic behavior honestly ✨

---

🌸 NAME 🌸

ti_sci_inta_alloc_irq — Allocate an irq within INTA domain 🎀

---

🦋 SYNOPSIS 🦋

struct ti_sci_inta_event_desc * ti_sci_inta_alloc_irq (struct irq_domain
*domain , u32 hwirq );

like, that's the whole signature, no cap 💅

---

⭐ ARGUMENTS ⭐

• domain — irq_domain pointer corresponding to INTA 🫶
• hwirq — hwirq of the input event 👑

---

🔥 NOTE 🔥

okay so Allocation happens in the following manner: — here's the tea, step by step:

• Find a free bit available in any of the vints available in the list. 🔍
• If not found, allocate a vint from the vint pool. 🧚
• Attach the free bit to input hwirq. Return event_desc if all went ok else appropriate error value. 😭

fr fr, if everything slays you get the event_desc, and if it doesn't you get the appropriate error value back. no skipping steps, bestie 💀
