🌸 NAME 🌸

okay so bestie, welcome to libnvme(9) — yes, the manual page itself — and the icon we're serving today is struct nvme_phy_rx_eom_log, aka the Physical Interface Receiver Eye Opening Measurement Log. It's literally the blueprint for that log, and we're about to go member by member. no skipping, periodt. ✨

🦋 SYNOPSIS 🦋

Here's the whole struct, copied exactly because we do not mess with the source, ever:

struct nvme_phy_rx_eom_log {
    __u8 lid;
    __u8 eomip;
    __le16 hsize;
    __le32 rsize;
    __u8 eomdgn;
    __u8 lr;
    __u8 odp;
    __u8 lanes;
    __u8 epl;
    __u8 lspfc;
    __u8 li;
    __u8 rsvd15[3];
    __le16 lsic;
    __le32 dsize;
    __le16 nd;
    __le16 maxtb;
    __le16 maxlr;
    __le16 etgood;
    __le16 etbetter;
    __le16 etbest;
    __u8 rsvd36[28];
    struct nvme_eom_lane_desc descs[];
};

💅 Members 💅

okay bestie, vibe check on every single member, in order, no cap:
