STRUCT SSAM_CDEV_EVENT_DESC(9)

💖 struct ssam_cdev_event_desc(9) 💖

okay bestie, welcome to the Kernel API Manual entry for struct ssam_cdev_event_desc — aka the little glow-up struct that tells the kernel which event you want to enable or disable and how to do it. she's giving "event descriptor" main character energy and honestly? iconic. 🎀

✨ SYNOPSIS ✨

struct ssam_cdev_event_desc {
    struct {
      __u8 target_category;
      __u8 target_id;
      __u8 cid_enable;
      __u8 cid_disable;
    } reg;
    struct {
      __u8 target_category;
      __u8 instance;
    } id;
    __u8 flags;
 };

no cap, that's the whole vibe. she's got two nested anonymous structs and one lone flags byte just chilling at the end. periodt. 💅

🌸 MEMBERS 🌸

• reg — the registry that the event gets enabled/disabled through. this is the ✨ how ✨ of the whole operation, fr fr.
  • reg.target_category — target category for the event registry requests. basically the filing cabinet label for the request. 🗂️
  • reg.target_id — target ID for the event registry requests. the specific drawer inside that cabinet. iykyk.
  • reg.cid_enable — the command ID for the event-enable request. this is the "turn it ON" button. 🔥
  • reg.cid_disable — the command ID for the event-disable request. and this is the "turn it OFF" button. 💀
• id — the ID that specifies which event we're talking about. the ✨ who ✨, if you will.
  • id.target_category — target category of the event source. which category of thing is generating this event.
  • id.instance — instance ID of the event source. which specific one of them it is, because sometimes there's a whole friend group of them. 🫶
• flags — the flags used for enabling the event. lowkey the seasoning on top of the whole struct. 🧂

🦋 DESCRIPTION 🦋

so the actual lore: this struct specifies which event should be enabled/disabled, and how to do that. that's it, that's the gig. she's a two-for-one deal — the target (id) plus the mechanism (reg) plus a sprinkle of flags. genuinely so efficient of her. 👑

🍓 little sign-off from the group chat: this page came from ./include/uapi/linux/surface_a... and it's dated October 2026, and it's still filed under struct ssam_cdev_event_desc(9). slay, and goodnight. ⭐
