STRUCT SDCA_ENTITY_XU(9)

💅 struct sdca_entity_xu(9) — like, the whole glow-up

okay so bestie, this is the kernel API manual page for struct sdca_entity_xu(9), and it's basically the little info packet that's specific to XU Entities. no cap, that's the whole NAME section. it's giving "small struct, big lore" ✨

🌸 SYNOPSIS 🌸

struct sdca_entity_xu {
    unsigned int max_delay;
    enum sdca_xu_reset_mechanism reset_mechanism;
 };

that's it. two members. iconic minimalism, honestly 🎀

✨ Members ✨

• max_delay — the maximum time, in microseconds, that the Device is allowed to take while changing the ownership from Device to Host. so like, the patience window before things get awkward 😭
• reset_mechanism — tells you which type of reset can be requested at the end of an FDL. the vibe check for how we're resetting. 🦋

👑 SEE ALSO 👑

also in Kernel file ./include/sound/sdca_function.h — and honestly the friend-group here is huge, so buckle up 🫶:

like I said. huge friend group. go say hi 💖

ngl bestie, max_delay is in microseconds and reset_mechanism is an enum sdca_xu_reset_mechanism — keep those exact, they're not vibes, they're facts. 🔥

and that's the whole page, periodt. 🌈 this one lives in the kernel source over at ./include/sound, and it's dated October 2026 — so yeah, it's a whole future era of manpage, main character energy only 👑💜
