STRUCT SSAM_CDEV_NOTIFIER_DESC(9)

🌸 struct ssam_cdev_notifier_desc(9) 🌸

okay bestie, so this is a page straight out of the Kernel API Manual — it's the struct ssam_cdev_notifier_desc page, section 9, and it's literally just a tiny little descriptor struct. small but iconic. let's get into it 💅

---

✨ NAME ✨

struct ssam_cdev_notifier_desc — the Notifier descriptor. that's it, that's the name. 🎀

---

🦋 SYNOPSIS 🦋

here's the whole struct, copied exactly, no cap:

struct ssam_cdev_notifier_desc {
    __s32 priority;
    __u8 target_category;
};

two members, both little cuties, both explained below 👇

---

💖 Members 💖

• priority — this is a priority value, and it decides the order in which notifier callbacks get called. higher value = higher priority, which means the associated callback runs earlier than the other callbacks with lower priority. so yeah, bigger number, first in line, main character energy 👑
• target_category — the event target category that this notifier should be receiving events for. basically it's the "which events are for me" filter 🎯

---

🌈 Description 🌈

so the whole vibe of this struct is: it specifies the notifier that should be registered or unregistered — specifically with which priority, and for which target category of events. that's the tea. it's giving "registration paperwork for a notifier" and honestly? we love a clean spec 🫶

---

⭐ SEE ALSO ⭐

go look at these if you wanna keep the lore going:

• Kernel file ./include/uapi/linux/surface_aggregator/cdev.h
• enum ssam_cdev_request_flags(9)
• struct ssam_cdev_request(9)
• struct ssam_cdev_event_desc(9)
• struct ssam_cdev_event(9)

---

💀 reminder bestie: keep the struct exactly as written. no renaming fields, no "improving" the types, no merging the two members into one creative vibe. __s32 and __u8 are staying right where they are, periodt.

and that's the page!! mwah 😭💜 huge sign-off energy: this came from ./include/uapi/linux/surface_a... and it's dated October 2026, so go forth and register your notifiers with the correct priority, bestie. slay 🧚‍♀️🌸
