ti_sci_set_device_state(9)

💖 NAME 💖

okay so bestie, welcome to the Kernel API Manual — this page is ti_sci_set_device_state(9), and it is literally the Set device state helper. that's the whole name, that's the vibe, we move 💅.

✨ SYNOPSIS ✨

here's the exact signature, no cap — keep it character-for-character:

int ti_sci_set_device_state (const struct ti_sci_handle *handle , u32 id
, u32 flags , u8 state );

🎀 ARGUMENTS 🎀

• handle — pointer to TI SCI handle. your little entry pass to the TI SCI universe 🫶.
• id — Device identifier. the device's name tag, basically.
• flags — flags to setup for the device. set them up, bestie ✨.
• state — State to move the device to. where the device is going on its little journey 💫.

🦋 RETURN 🦋

returns 0 if all went well, else returns appropriate error value. so 0 is the slay, and anything else means the universe is telling you something's off. periodt 💀.

mwah 💋 — this cutie comes from ./drivers/firmware, dated October 2026, and the page title is still ti_sci_set_device_state(9). bye bestie, go set some device states responsibly 🫶✨
