📦 version 7.3.1, in nixpkgs unstable

💅 ti_sci_cmd_proc_handover — the Kernel API Manual, bestie edition 🎀

okay so real quick — this page lives in the Kernel API Manual, section 9, and it's about one function: ti_sci_cmd_proc_handover. It's giving "let me pass the aux cord" but for a whole physical processor. 🧚

✨ NAME ✨

ti_sci_cmd_proc_handover — the command that hands over control of a physical processor to a host that's in that processor's access control list. literally passing the crown 👑 to someone who's already on the VIP list.

🌸 SYNOPSIS 🌸

int ti_sci_cmd_proc_handover(const struct ti_sci_handle *handle, u8 proc_id, u8 host_id);

that's the whole vibe check. three args, one int back. slay. ✨

🦋 ARGUMENTS 🦋

  • handle — pointer to the TI SCI handle. it's the main character you're handing to the driver so it knows who it's talking to 🫶
  • proc_id — the processor ID this request is for. which processor are we doing all this for, bestie? 👀
  • host_id — the host ID that's getting control of the processor. the one getting the keys 🔑

💖 RETURN 💖

0 if everything went well — iconic, no notes 💅 — otherwise it returns the appropriate error value. so if it's not 0, something went sideways and you should lowkey pay attention 😭

🎀 SEE ALSO 🎀

bestie. buckle up. this list is long but every single one of these is required reading, fr fr — no skipping, i'm watching 🙈

ngl that's a lot of cross-refs but that's the whole ti_sci cinematic universe right there 🌈 eat your heart out, MCU.

aaaand that's the page, bestie 🍓 this gem dropped October 2026 and it lives in ./drivers/firmware — go touch some kernel source, ily, bye 💜✨
