ti_sci_inta_set_type(9)

💅 ti_sci_inta_set_type — the Kernel API Manual page, bestie edition

okay so this is ti_sci_inta_set_type(9), straight outta the Kernel API Manual ✨ it's a lil function that changes up how an irq gets triggered, and honestly? iconic behaviour.

---

🌸 NAME 🌸

ti_sci_inta_set_type — literally just updates the trigger type of the irq. that's it, that's the whole gig 💅

---

✨ SYNOPSIS ✨

int ti_sci_inta_set_type (struct irq_data *data , unsigned int type );

like, it hands you back an int and takes those two args. slay 🫶

---

🎀 ARGUMENTS 🎀

• data — a pointer to the corresponding irq_data. that's your main character right there 👑
• type — the trigger type, as specified by user. yes, that means you get to decide 🦋

---

💖 NOTE 💖

this updates the handle_irq callback for level msi. no cap, that's the actual vibe of it.

and the return? it returns 0 if all went well — else it returns the appropriate error 😭 so like, check your return value, bestie, fr fr.

ngl, if you get something that isn't 0, that's your sign something went sideways. handle it 🙈
