ti_sci_set_irq(9)

💫 ti_sci_set_irq (9) — Kernel API Manual 💫

okay so bestie, welcome to the Kernel API Manual page for ti_sci_set_irq(9) — it's the helper api that configures the irq route between the source you asked for and the destination you asked for 🎀 like it literally just wires up the interrupt road trip, iykyk.

---

✨ NAME ✨

ti_sci_set_irq — Helper api to configure the irq route between the requested source and destination 🦋

---

🌸 SYNOPSIS 🌸

int ti_sci_set_irq (const struct ti_sci_handle *handle , u32
valid_params , u16 src_id , u16 src_index , u16 dst_id , u16
dst_host_irq , u16 ia_id , u16 vint , u16 global_event , u8
vint_status_bit , u8 s_host );

no cap, that's a lot of parameters, but every single one is doing its little job 💅

---

🎀 ARGUMENTS 🎀

• handle — Pointer to TISCI handle. your main character struct, fr fr 🫶
• valid_params — Bit fields defining the validity of certain params. it's giving "which of my friends actually showed up to the group chat" energy ⭐
• src_id — Device ID of the IRQ source. where the interrupt is coming from 💜
• src_index — IRQ source index within the source device. the little slot number inside that device, yep 🍓
• dst_id — Device ID of the IRQ destination. where it's headed 💖
• dst_host_irq — IRQ number of the destination device. the specific irq number on the destination side 🔥
• ia_id — Device ID of the IA, if the IRQ flows through this IA. only relevant when it passes through, okay? 🌸
• vint — Virtual interrupt to be used within the IA. the virtual one 🌈
• global_event — Global event number to be used for the requesting event. the event's global passport number ngl 🦋
• vint_status_bit — Virtual interrupt status bit to be used for the event. literally the status bit 🎀
• s_host — Secondary host ID to which the irq/event is being requested for. yes it ends in a period in the original and yes we respect it 💅

---

⭐ RETURN ⭐

0 if all went fine, else return appropriate error. that's it, that's the vibe check — zero means slay, anything else means something's up 😭

bestie, this page lives in ./drivers/firmware and it's dated October 2026 — so go configure those irq routes and absolutely slay the day, mwah 💋✨🎀
