STRUCT QAIC_WAIT(9)

👑 struct qaic_wait(9) — a vibe check on the Kernel API Manual, bestie

okay so picture this: you're out here in kernel land, and you need something to actually wait for your BO to finish doing its little execution thing. That's literally what this struct is. It's the "hold up, don't go anywhere yet" of the qaic world. no cap. 🎀

✨ NAME ✨

struct qaic_wait — it defines a blocking wait for BO execution. that's it, that's the whole personality 💅

🦋 SYNOPSIS 🦋

struct qaic_wait {
    __u32 handle;
    __u32 timeout;
    __u32 dbc_id;
    __u32 pad;
 };

like, look at her. four little fields. main character energy fr fr 🌸

💖 Members 💖

• handle — In. the GEM handle of the BO you're waiting on. this is the one you're obsessed with, the whole reason you're here 🫶
• timeout — In. max time in ms to wait for that BO. your patience, quantified ⏳
• dbc_id — In. the DBC that the BO gets submitted to. gotta know where she's going ✨
• pad — structure padding. must be 0. not "should", not "maybe", must. don't be chaotic about it, bestie 💀
