UNION LEAPRAID_REP_DESC_UNION(9)

💖 NAME 💖

okay so bestie, meet union leapraid_rep_desc_union(9) — the unified reply descriptor format from the Kernel API Manual. It’s giving “one descriptor, multiple little views” energy, and honestly? iconic. 🦋

✨ SYNOPSIS ✨

       union leapraid_rep_desc_union {
           struct leapraid_rep_desc {
             u8 rep_flg;
             u8 msix_idx;
             __le16 taskid;
             u8 r1[4];
           } dflt_rep;
           struct leapraid_add_rep_desc {
             u8 rep_flg;
             u8 msix_idx;
             __le16 taskid;
             __le32 rep_frame_addr;
           } addr_rep;
           __le64 words;
           struct {
             u32 low;
             u32 high;
           } u;
        };

🫶 MEMBERS 🫶

Here’s the member-by-member vibe check, no cap:

• dflt_rep — the default reply descriptor, and it’s holding the basic completion info. 💅
  • dflt_rep.rep_flg — reply flag that says what the reply type or status is. ✨
  • dflt_rep.msix_idx — MSI-X index for interrupt routing. 🎀
  • dflt_rep.taskid — task identifier that matches the submitted request. 🫶
• addr_rep — the address reply descriptor, used when firmware returns a memory address tied to the reply. 🌸
  • addr_rep.rep_flg — reply flag indicating reply type or status. ✨
  • addr_rep.msix_idx — MSI-X index for interrupt routing. 🎀
  • addr_rep.taskid — task identifier matching the submitted request. 🫶
  • addr_rep.rep_frame_addr — physical address of the reply frame. 🔥
• words — raw 64-bit representation of the reply descriptor. 👑
• u — alternative access using 32-bit low/high words. 🦋
  • u.low — lower 32 bits of the descriptor. 💜
  • u.high — upper 32 bits of the descriptor. 💜
