UNION LBC_INVAL_STATUS(9)

💅 NAME 💅

okay so bestie, this is union lbc_inval_status — the LBC Invalidation status register — from the Kernel API Manual. The page name is literally union lbc_inval_status(9), and it's giving very "hardware register but make it a union" energy. 💖

✨ SYNOPSIS ✨

Here's the whole definition, copied exactly so you can trust it, no cap:

       union lbc_inval_status {
           u64 value;
           struct {
         #if (defined(__BIG_ENDIAN_BITFIELD));
             u64 raz3 : 23;
             u64 cam_clean_entry_complete_cnt : 9;
             u64 raz2 : 7;
             u64 cam_clean_entry_cnt : 9;
             u64 raz1 : 5;
             u64 cam_inval_state : 3;
             u64 raz0 : 5;
             u64 cam_inval_abort : 1;
             u64 cam_rst_rdy : 1;
             u64 done : 1;
         #else;
             u64 done : 1;
             u64 cam_rst_rdy : 1;
             u64 cam_inval_abort : 1;
             u64 raz0 : 5;
             u64 cam_inval_state : 3;
             u64 raz1 : 5;
             u64 cam_clean_entry_cnt : 9;
             u64 raz2 : 7;
             u64 cam_clean_entry_complete_cnt : 9;
             u64 raz3 : 23;
         #endif;
           } s;
        };

There's a u64 value; and a nested struct { ... } s; inside the union. The struct has two preprocessor branches — one under #if (defined(__BIG_ENDIAN_BITFIELD)); and one under #else; — and each branch lists its bitfields exactly as shown. Those semicolons on the preprocessor lines are in the original too; I did not touch them. 💅
