UNION ECC_ERROR_INFO(9)

✨ union ecc_error_info(9) ✨

okay so bestie, welcome to the Kernel API Manual — this is the page for union ecc_error_info, and it's literally the little data blob that holds your ECC error log info 💅 no cap, it's giving "tiny struct, big responsibilities."

🌸 NAME 🌸

union ecc_error_info — ECC error log information. that's it, that's the whole vibe 🎀

---

🦋 SYNOPSIS 🦋

union ecc_error_info {
    struct {
      u32 burstpos:3;
      u32 lrank:4;
      u32 rank:2;
      u32 group:3;
      u32 bank:2;
      u32 col:11;
      u32 row:7;
      u32 rowhi;
    };
    u64 i;
 };

look at her. she's a union, she's got a bitfield struct inside, she's got a u64 — main character energy fr fr 🔥

• lrank — Logical Rank number.
• rank — Rank number.
• group — Group number.
• bank — Bank number.
• col — Column number.
