UNION IONIC_DEV_IDENTITY(9)

💖 union ionic_dev_identity(9) 💖

okay so welcome to the Kernel API Manual page for union ionic_dev_identity, bestie. This is literally the device identity info bundle — all the provisioned counts, interrupt-coalescing math, timestamp scaling, and capabilities side of things. It's giving “I contain multitudes, but make it a union.” ✨

🦋 NAME 🦋

union ionic_dev_identity — device identity information. No cap, this is the identity tea for the device. 💅

🎀 SYNOPSIS 🎀

union ionic_dev_identity {
    struct {
      u8 version;
      u8 type;
      u8 rsvd[2];
      u8 nports;
      u8 rsvd2[3];
      __le32 nlifs;
      __le32 nintrs;
      __le32 ndbpgs_per_lif;
      __le32 intr_coal_mult;
      __le32 intr_coal_div;
      __le32 eq_count;
      __le64 hwstamp_mask;
      __le32 hwstamp_mult;
      __le32 hwstamp_shift;
      __le64 capabilities;
    };
    __le32 words[478];
 };

🌸 Members 🌸

• {unnamed_struct} — it's anonymous, and honestly? mysterious main-character energy. 🫶
• version — the Version of device identify. That's the wording, bestie; we keep it. 💖
• type — Identify type, with 0 for now.
• rsvd — reserved byte(s). We do not touch. We respect the reserved byte(s). 🎀
• nports — Number of ports provisioned.
• rsvd2 — reserved byte(s), round two. Still reserved, still iconic.
• nlifs — Number of LIFs provisioned.
• nintrs — Number of interrupts provisioned.
• ndbpgs_per_lif — Number of doorbell pages per LIF.
• intr_coal_mult — Interrupt coalescing multiplication factor. It scales a user-supplied interrupt coalescing value in usecs to device units using: device units = usecs * mult / div
• intr_coal_div — Interrupt coalescing division factor. Same scaling situation, bestie: it scales a user-supplied interrupt coalescing value in usecs to device units using: device units = usecs * mult / div
• eq_count — Number of shared event queues.
• hwstamp_mask — Bitmask for subtraction of hardware tick values.
• hwstamp_mult — Hardware tick to nanosecond multiplier.
• hwstamp_shift — Hardware tick to nanosecond divisor (power of two).
• capabilities — Device capabilities. Slay. 🔥
• words — word access to struct contents.
