💅 mei_me_trc_status — kernel API manual, but make it make sense

okay so bestie, welcome to the mei_me_trc_status(9) page ✨ this is a kernel API manual page (section 9, the "fun one" for kernel devs, iykyk) and it's honestly so short, we can absolutely get through it together 🫶

🌸 NAME 🌸

mei_me_trc_status — literally just: read the trc status register 💖

that's it. that's the whole name section. iconic behavior, no notes.

🎀 SYNOPSIS 🎀

here's the vibe check on the actual signature:

int mei_me_trc_status (struct mei_device *dev , u32 *trc );

so it takes two things and gives you back an int. main character energy fr 💅

🦋 ARGUMENTS 🦋

okay so when you call it, these are the two besties you gotta bring along:

  • dev — the mei device 🌈 like, the actual device struct you're working with
  • trc — the trc status register value, and yes it's a pointer (u32 *) so it can hand the value back out to you 💖

⭐ RETURN ⭐

  • 0 on success 👑
  • error otherwise 😭 (that's the whole spec, no cap — the page doesn't get more specific than that, so don't come for me)

🧚 SEE ALSO 🧚

okay this is the part where the manpage goes absolutely feral and lists EVERYTHING. it's giving "tag yourself, I'm mei_me_pg_legacy_enter_sync(9)" 💀

first up, the kernel file it lives in: ./drivers/misc/mei/hw-me.c 🍓 and then the whole extended friend group:

like I said. feral. but every single one is here because I would never do you dirty like that 🙈💜

lowkey a note: this is a kernel API page, so it's describing the function for people writing/reviewing kernel code — not a command you run in your shell. just so we're clear, bestie 💅

okay and finally, the cute little sign-off corner 🎀 this page lives in ./drivers/misc/mei, dated October 2026, and it's filed under mei_me_trc_status(9) — slay, go read the register, you're gonna do amazing 🌈✨💖
