STRUCT LEAPRAID_SEP_REQ(9)

💖 NAME 💖

okay so this is struct leapraid_sep_req, bestie — it's the SEP (SCSI Enclosure Processor) request struct. that's it, that's the whole name. no cap.

✨ SYNOPSIS ✨

here's the whole shape of it, literally verbatim, don't @ me:

struct leapraid_sep_req {
    __le16 dev_hdl;
    u8 chain_offset;
    u8 func;
    u8 act;
    u8 flg;
    u8 r1;
    u8 msg_flag;
    u8 r2[4];
    __le32 slot_status;
    u8 r3[12];
    __le16 slot;
    __le16 enc_hdl;
 };

🌸 MEMBERS 🌸

okay so let's go member by member, no skips, we're doing the whole tour 🫶

• dev_hdl — the device handle. that's the whole vibe, it's how you know which device we're talking about 💅
• chain_offset — offset for the chained SGE. chained. SGE. yep ✨
• func — function code. the what are we even doing field.
• act — action to perform. the okay but actually do it field 🎀
• flg — flags.
• r1 — reserved. as in, hands off, it's not for you 🙈
• msg_flag — message flags.
• r2 — reserved again. yes there's more of them.
• slot_status — slot status.
• r3 — reserved. again. there are a lot of these, it's giving "we saved seats for our friends" 💀
• slot — the slot number.
• enc_hdl — enclosure handle. the enclosure in question 🦋

ok and one last thing before you go — this whole page lives in ./drivers/scsi/leapraid, and it's dated October 2026. so it's from the future, kind of iconic of it honestly 👑✨ go read the header file, it ate 💅
