STRUCT OPTEE_CALL_WAITER(9)

💅 NAME

ok so bestie, gather round — struct optee_call_waiter is literally just the lil waiting-room ticket for TEE entry, because sometimes your call has to wait for a free TEE thread to open up. no cap, that's the whole vibe. 🎟️✨

(this is from the Kernel API Manual, and yes we're talking about struct optee_call_waiter(9) — say hi 👋)

---

✨ SYNOPSIS ✨

here's the whole shape of it, exactly as it lives, no edits from me 🫶

struct optee_call_waiter {
    struct list_head list_node;
    struct completion c;
    bool sys_thread;
 };

---

🎀 Members 🎀

ok so three fields, three lil personalities:

• list_node — this is the reference in the waiters list. it's how your waiter is linked up with all the other waiters hanging out in line 💫
• c — the waiting completion reference. this is the "omg are we there yet" signal right here 🌸
• sys_thread — a bool, and it's true if the waiter belongs to a system thread. yep, that's the entire criteria, iconic honestly 👑

ngl, it's a small struct but it's doing main character energy work behind the scenes — waiting for a free TEE thread is the whole point 🔥

🌈 SEE ALSO 🌈

if you wanna go down the rabbit hole (and you do, iykyk), the kernel file lives at ./drivers/tee/optee/optee_private.h, and it's friends with all of these:

• struct optee_call_queue(9)
• struct optee_supp(9)
• struct optee_pcpu(9)
• struct optee_smc(9)
• struct optee_ffa(9)
• struct optee_revision(9)
• struct optee_ops(9)
• struct optee(9)

like a whole little optee friend group fr fr 🦋💜
