✨ gaokun_ec_ucsi_read — the kernel API manual, bestie edition ✨

Okay so picture this: it's gaokun_ec_ucsi_read(9), a real one from the Kernel API Manual, and honestly? She's giving "small function, big responsibilities." Let's get into it 💅

🌸 NAME 🌸

gaokun_ec_ucsi_read — literally just reads UCSI data from the EC. That's the whole vibe. No cap. 💖

🦋 SYNOPSIS 🦋

int gaokun_ec_ucsi_read (struct gaokun_ec *ec , u8
resp[GAOKUN_UCSI_READ_SIZE] );

Look at her signature. Iconic. Notice the return type is int, and yes we will be talking about that in the RETURN section, so stay with me 🎀

🎀 ARGUMENTS 🎀

  • ec — the gaokun_ec structure. Your main character struct, fr fr. 👑
  • resp — the buffer where the response sequence gets stored. She's the designated receptacle for the goods. 🍓

⭐ DESCRIPTION ⭐

So what does she actually do? She reads CCI and MSGI, and those are the ones used by the UCSI subdriver. That's it, that's the whole description, and honestly sometimes less is more, iykyk. 🧚

Ngl, that's the entire documented behavior. Don't go inventing extra powers for her — she's not that kind of function. 💀

🔥 RETURN 🔥

0 on success, or a negative error code if things went sideways. So like... check her return value, bestie. Always. 🙈

🌈 SEE ALSO 🌈

The kernel file lives right here: ./drivers/platform/arm64/huawei-gaokun-ec.c — go read the source, it's giving lore.

And here's the whole friend group, all of them cross-referenced and accounted for:

💜 THE SIGN-OFF 💜

This little baddie came out of ./drivers/platform/arm64 and is dated October 2026 — mark your calendars, she's from the future apparently. Anyways bestie, go forth and read your UCSI data responsibly 🫶💖✨
