STRUCT DMUB_CURSOR_OFFLOAD_PIPE_DATA_V1(9)

💅 struct dmub_cursor_offload_pipe_data_v1

okay so bestie, welcome to the Kernel API Manual, section 9 — we're looking at struct dmub_cursor_offload_pipe_data_v1, and the name literally tells you everything: it's the per pipe data for cursor offload 🎯 that's the whole vibe.

---

🌸 NAME

struct dmub_cursor_offload_pipe_data_v1 — per pipe data for cursor offload. that's it, that's the girl. she holds the cursor-offload data for one pipe, and she's been doing it since v1 ✨

---

🦋 SYNOPSIS

here's her whole lewk, copy it exactly okay, no typos, she's sensitive about that:

struct dmub_cursor_offload_pipe_data_v1 {
    union {
      struct dmub_cursor_offload_pipe_data_dcn30_v1 dcn30;
      struct dmub_cursor_offload_pipe_data_dcn401_v1 dcn401;
      struct dmub_cursor_offload_pipe_data_dcn60_v1 dcn60;
      uint8_t payload[96];
    };
 };

like… it's giving "one struct, four faces" 💀 it's a union, so all those members are chilling in the same spot — dcn30, dcn401, dcn60, and a uint8_t payload[96] raw-bytes option. pick your era, bestie 🎀

---

👑 Members

• {unnamed_union} — anonymous 🙈 that's genuinely what the manpage says: the union has no name. she's mysterious. she's unnamed. no handle to grab, no label to call her by — the union is just anonymous. iconic honestly.

ngl bestie, that's genuinely the entire page — no options, no exit statuses, no environment variables, nothing hiding. just a union, a 96-byte payload, and a lot of see-also links. slay. 🫶

and that's a wrap! 💖 this lil page came from <pink>./drivers/gpu/drm/amd/display/...</pink> and it's dated October 2026 — so yeah, she's from the future and still showing up in the Kernel API Manual, section 9, exactly as struct dmub_cursor_offload_pipe_data_v1(9). periodt 🌈⭐
