STRUCT SSAM_CDEV_EVENT(9)

🌸 NAME 🌸

Okay bestie, gather round: struct ssam_cdev_event is the SSAM event sent by the EC. That's the whole name vibe. This lil page is from the struct ssam_cdev_event(9) entry in the Kernel API Manual, and we're about to get into every field like it's a group-chat screenshot. 💅

✨ SYNOPSIS ✨

Here's the struct in all its glory — exact tokens, no cap:

struct ssam_cdev_event {
    __u8 target_category;
    __u8 target_id;
    __u8 command_id;
    __u8 instance_id;
    __u16 length;
    __u8 data[];
};

🎀 Members 🎀

These are the members, and yes, we're listing every single one. Obsessed with the consistency. 🫶

• target_category — target category of the event source. For the full lore, see enum ssam_ssh_tc. iykyk.
• target_id — target ID of the event source. Slay, identifier.
• command_id — command ID of the event. The command in question has a whole ID, periodt.
• instance_id — instance ID of the event source. Another ID, another icon.
• length — length of the event payload in bytes. Count the bytes, bestie.
• data — event payload data. The actual payload goodies live here. 🍓

And that's the tea 🫖: source/version is ./include/uapi/linux/surface_a..., dated October 2026, and the page is struct ssam_cdev_event(9). Byeee, go read the kernel docs bestie 💖✨
