STRUCT TI_SCI_MSG_REQ_SET_IO_ISOLATION(9)

💅 struct ti_sci_msg_req_set_io_isolation(9) 💅

okay bestie, welcome to the Kernel API Manual — yes, that's the manual name, and yes, this page is a little struct in it. Buckle up, it's a short one but it's lowkey important 🫶

---

✨ NAME ✨

struct ti_sci_msg_req_set_io_isolation — it's literally the request for TI_SCI_MSG_SET_IO_ISOLATION. That's it, that's the whole name. Periodt 💅

---

🌸 SYNOPSIS 🌸

here's the whole shape of it, no cap:

struct ti_sci_msg_req_set_io_isolation {
    struct ti_sci_msg_hdr hdr;
    u8 state;
 };

look at her. two members. main character energy, minimal effort 💖

---

🎀 Members 🎀

• hdr — the generic header, the little backpack every TI-SCI message carries around 🎒
• state — the deseared state of the IO isolation. yep, that's what the original says, we don't editorialise, we just report 🫡

---

🦋 Description 🦋

so this message is the one you send when you want to enable or disable IO isolation for low power modes ✨ like, it's the "hey can we isolate the IO pretty please" note.

and the response? it's just a generic ACK / NACK message. that's it. no essay back, just a thumbs up or a thumbs down 😭

genuine question: is that not the longest SEE ALSO you've ever seen?? go off king 👑
