STRUCT OPTEE_CALL_QUEUE(9)

💅 struct optee_call_queue(9) — like, the OP-TEE call queue management era

okay so bestie, welcome to the Kernel API Manual page for struct optee_call_queue, and no cap, this lil struct is the whole group chat moderator for OP-TEE calls. it's giving backstage-pass energy. let's get into it 💖

---

✨ NAME ✨

struct optee_call_queue — OP-TEE call queue management. that's it, that's the vibe. she manages the queue, she runs the queue, she is the queue 🎀

---

🌸 SYNOPSIS 🌸

here's the whole struct, exactly as she comes, no edits, no notes:

struct optee_call_queue {
    struct mutex mutex;
    struct list_head waiters;
    int total_thread_count;
    int free_thread_count;
    int sys_thread_req_count;
 };

like, gaze upon her. five fields. immaculate. 🔥

👑 Members 👑

okay so each of these is a whole personality, let's meet the cast:

• mutex — serializes access to this struct. she's the bouncer at the door fr, one thread in at a time, no cutting the line 💅
• waiters — list of threads waiting to enter OP-TEE. literally the line outside the club, everybody hoping to get let in 🙈
• total_thread_count — overall number of thread context in OP-TEE, or 0. so it's the full headcount, and yes, 0 is a valid answer, she can be empty 🫶
• free_thread_count — number of threads context free in OP-TEE. the available ones. the unoccupied ones. the "come on in, we have room" ones ✨
• sys_thread_req_count — number of registered system thread sessions. the system thread girlies who signed up and are officially on the list 🦋
