UNION EFL_RNM_CTL_STATUS(9)

💅 efl_rnm_ctl_status(9) — Kernel API Manual 💅

okay bestie, this page is for union efl_rnm_ctl_status, and it’s literally the RNM Control and Status Register. It’s a union, it’s got a struct, and it’s giving endian-conditional bitfield energy. Let’s go 🫶

🌸 NAME 🌸

union efl_rnm_ctl_status — RNM Control and Status Register. That’s the whole name, no cap.

✨ SYNOPSIS ✨

Here’s the exact layout, copied with love and zero changes:

union efl_rnm_ctl_status {
    u64 value;
    struct {
  #if (defined(__BIG_ENDIAN_BITFIELD));
      u64 raz_9_63 : 55;
      u64 ent_sel : 4;
      u64 exp_ent : 1;
      u64 rng_rst : 1;
      u64 rnm_rst : 1;
      u64 rng_en : 1;
      u64 ent_en : 1;
  #else;
      u64 ent_en : 1;
      u64 rng_en : 1;
      u64 rnm_rst : 1;
      u64 rng_rst : 1;
      u64 exp_ent : 1;
      u64 ent_sel : 4;
      u64 raz_9_63 : 55;
  #endif;
    } s;
};

The page has a Members section, but it doesn’t list any member entries under it. The fields are the ones in the struct above — that’s the tea. 🍵
