UNION EMU_AE_ENABLE(9)

💖 union emu_ae_enable(9) 💖

okay so bestie, this is the Kernel API Manual page for union emu_ae_enable — the EMU Asymmetric engines situation. It’s a C union, and the whole vibe is bitfield layout energy. Let’s get into it 💅

✨ NAME ✨

union emu_ae_enable — EMU Asymmetric engines.

🦋 SYNOPSIS 🦋

       union emu_ae_enable {
           u64 value;
           struct {
         #if (defined(__BIG_ENDIAN_BITFIELD));
             u64 raz : 44;
             u64 enable : 20;
         #else;
             u64 enable : 20;
             u64 raz : 44;
         #endif;
           } s;
        };

okay so quick read: there’s a u64 value; and an anonymous struct s. The #if checks defined(__BIG_ENDIAN_BITFIELD); on that branch s has u64 raz : 44; then u64 enable : 20;, and on the #else branch it flips to u64 enable : 20; then u64 raz : 44;. Both are u64 bitfields — raz is 44 bits and enable is 20 bits. periodt 💅

👑 Members 👑

this section is empty in the original page — literally zero members listed here, no cap. The actual fields live in the SYNOPSIS code above: value and the struct s. don’t come for me, I’m not inventing extra stuff 🙈
