UNION LBC_INVAL_CTL(9)

🌸 NAME 🌸

okay bestie, we're in the Kernel API Manual and this page is union lbc_inval_ctl(9) — the LBC invalidation control register. that's the whole NAME section, short and iconic. 💅

---

✨ SYNOPSIS ✨

here's the union in all its bitfield glory, copied exactly so you don't have to squint at the original:

       union lbc_inval_ctl {
           u64 value;
           struct {
         #if (defined(__BIG_ENDIAN_BITFIELD));
             u64 raz2 : 48;
             u64 wait_timer : 8;
             u64 raz1 : 6;
             u64 cam_inval_start : 1;
             u64 raz0 : 1;
         #else;
             u64 raz0 : 1;
             u64 cam_inval_start : 1;
             u64 raz1 : 6;
             u64 wait_timer : 8;
             u64 raz2 : 48;
         #endif;
           } s;
        };

yes, both endian branches are really there — don't @ me, that's the original vibe. 🦋

🎀 Members 🎀

not me opening the Members section and finding it literally empty 😭. the original page has no member descriptions here — none, zero, nada. all the member names and shapes live in the SYNOPSIS above, and i'm not about to invent lore.

the fields in that struct include value, s, raz0, cam_inval_start, raz1, wait_timer, and raz2. periodt. 🫶
