STRUCT QAIC_MANAGE_TRANS_PASSTHROUGH(9)

🎀 NAME 🎀

okay so bestie, welcome to the Kernel API Manual page for struct qaic_manage_trans_passthrough(9) — the header up top literally renders the manual name as struct qaic_..._passthrough(9) (ellipsis and all, iykyk 💅). Its whole personality? Defines a passthrough transaction. That's the job, and it ate. ✨

✨ SYNOPSIS ✨

the exact shape, no cap:

struct qaic_manage_trans_passthrough {
    struct qaic_manage_trans_hdr hdr;
    __u8 data[];
};

note the data[] — brackets exactly as shown, we are not out here editorializing the syntax. 🫶

💖 Members 💖

• hdr — In. Header to identify this transaction. it's the little ID badge so everyone knows which transaction is which — honestly iconic. 🏷️
• data — In. Payload of this transaction. Opaque to the driver — yes, literally opaque, that's the spec word, bestie. Userspace must encode in little endian and align/pad to 64-bit. This is a must-must, not a maybe: little endian, then align/pad to 64-bit, periodt. 🔥

⚠️ vibe check on data: the page says it's opaque to the driver, and userspace must encode in little endian and align/pad to 64-bit. Do not freestyle the endianness or the padding, fr fr. 🙈
