STRUCT CROS_EC_COMMAND(9)

💖 struct cros_ec_command(9) 💖

okay so bestie, welcome to the Kernel API Manual page for struct cros_ec_command — yes that's the manual name, it's giving "I live in the kernel docs now" and honestly? iconic. this one's all about the info that describes a ChromeOS EC command. let's get into it 🦋

✨ NAME ✨

struct cros_ec_command — literally just the info about a ChromeOS EC command. that's the whole vibe. no cap. 💅

🌸 SYNOPSIS 🌸

struct cros_ec_command {
    uint32_t version;
    uint32_t command;
    uint32_t outsize;
    uint32_t insize;
    uint32_t result;
    uint8_t data[];
};

look at her. five uint32_ts and one gorgeous flexible uint8_t data[] array. main character struct fr fr 👑

🎀 Members 🎀

• version — the command version number (often 0, so don't stress it bestie 🫶).
• command — the actual command to send, and it's an EC_CMD_... one, iykyk.
• outsize — the outgoing length, in bytes. how much you're yeeting out the door.
• insize — the max number of bytes to accept from the EC. like a little bouncer at the club, strictly capping what comes back in 💀
• result — the EC's response to the command. and yes, this is separate from a communication failure — so a bad result and a broken chat are two different problems, keep that straight 🙈
• data — where the incoming data from the EC goes, and where the outgoing data to the EC comes from. both directions, one spot, she's doing double duty and slaying it ✨

go read those, they're all part of the same friend group bestie 💜

anyway that's the whole page, mwah 💋 — this came from ./include/linux/platform_data, dated October 2026, and it's struct cros_ec_command(9) forever and always. periodt. 🌈
