💅 gaokun_ec_ucsi_get_reg — a Kernel API Manual moment ✨

okay so bestie, welcome to the Kernel API Manual entry for gaokun_ec_ucsi_get_reg(9) — she's a little function, she's lowkey the whole vibe, and she's about to make so much sense to you. sit down, grab a snack 🍓, and let's go.

🌸 NAME 🌸

gaokun_ec_ucsi_get_reg — literally just: get the UCSI register from the EC. that's it. that's the whole job. no cap 💅

✨ SYNOPSIS ✨

int gaokun_ec_ucsi_get_reg (struct gaokun_ec *ec , struct
       gaokun_ucsi_reg *ureg );

she takes two things and gives you back an int. iconic behavior honestly 🫶

🎀 ARGUMENTS 🎀

  • ec — the gaokun_ec structure. your main character struct, the one everything else hangs off of ✨
  • ureg — the gaokun UCSI register. this is where the register data ends up, so like… she's the destination, the moment, the whole point 💖

🦋 DESCRIPTION 🦋

she gets the UCSI register data — and yes, she's used by the UCSI subdriver, so she's got people depending on her. very main character energy if you think about it 👑

⭐ RETURN ⭐

  • 0 on success 🎉 — slay, everything worked
  • a negative error code if it didn't 😭 — no further detail given, that's just how she is

🔥 SEE ALSO 🔥

the kernel file she lives in, for when you need to go straight to the source:

Kernel file ./drivers/platform/arm64/huawei-gaokun-ec.c

and her whole friend group, fr fr — all of these are absolutely worth a read:

and that's the page, bestie 🌈 this cutie came out of ./drivers/platform/arm64 back in October 2026 — so when you're out here reading gaokun_ec_ucsi_get_reg(9), just know she's been serving register data since then 💜 mwah 💋
