UNION AQM_GRP_EXECMSK_HI(9)

✨ union aqm_grp_execmsk_hi(9) ✨

okay so bestie, we're diving into the Kernel API Manual for real and this one's a union — a union, not a struct, don't @ me — called union aqm_grp_execmsk_hi, and it is literally all about the Available AE engines for the group 💅

---

🌸 NAME 🌸

union aqm_grp_execmsk_hi — Available AE engines for the group 🎀

---

🦋 SYNOPSIS 🦋

union aqm_grp_execmsk_hi {
    u64 value;
    struct {
  #if (defined(__BIG_ENDIAN_BITFIELD));
      u64 raz_40_63 : 24;
      u64 exec_40_to_79 : 40;
  #else;
      u64 exec_40_to_79 : 40;
      u64 raz_40_63 : 24;
  #endif;
    };
 };

no cap, that's the whole shape of it — a u64 value that overlaps with an anonymous struct, and the bitfield order flips depending on whether __BIG_ENDIAN_BITFIELD is defined 🔥

🧚 Members 🧚

• {unnamed_struct} — anonymous, bestie. it has no name. it simply is. main character energy tbh 🙈
• exec_40_to_79 — AE engines 40 to 79 status 👑
• exec_40_to_79 — AE engines 40 to 79 status 💀

yes, it's listed twice in the source docs. not a typo on my end, i promise — that's genuinely how it's written, so i'm keeping both, fr fr. one for each endian branch mentally, iykyk.
