STRUCT MPI3MR_LOGDATA_ENTRY(9)

💅 struct mpi3mr_logdata_entry(9) — Kernel API Manual, bestie edition ✨

okay so welcome to the glow-up of the mpi3mr_logdata_entry page, straight out of the Kernel API Manual 💖 no cap, this one's a little baby struct but she's got a job to do.

---

🎀 NAME 🎀

struct mpi3mr_logdata_entry — the log data entry that gets cached by the driver, periodt. 💅

---

✨ SYNOPSIS ✨

here's the whole vibe, verbatim, don't touch a single character bestie:

struct mpi3mr_logdata_entry {
    __u8 valid_entry;
    __u8 rsvd1;
    __u16 rsvd2;
    __u8 data[1];
 };

---

🦋 Members 🦋

lowkey a tiny cast of characters, but every single one matters:

• valid_entry — is the entry valid? that's it, that's the whole job, this one little field tells you whether you should actually trust what you're looking at 🔥
• rsvd1 — Reserved. she's just sitting there, don't touch her 🙈
• rsvd2 — Reserved too. more reserved energy, respect the padding 💀
• data — the actual payload: variable length log entry data, so she stretches however long the entry needs to be 🌈

🫶 reminder bestie: rsvd1 and rsvd2 are Reserved — like, do not repurpose them, do not get creative. leave them alone.
