STRUCT DMUB_CMD_CURSOR_OFFLOAD_INIT_DATA(9)

💅 STRUCT DMUB_CMD_CURSOR_OFFLOAD_INIT_DATA(9) — the kernel API manual, but make it make sense 🎀

okay so this is a page from the Kernel API Manual (that's the manual name bestie, we're not copying the whole header line, we're folding it in like a secret), and it's all about this one little struct. Buckle up, it's short but it's iconic. ✨

---

🌸 NAME 🌸

struct dmub_cmd_cursor_offload_init_data — literally just the payload for the cursor offload init command. that's it. that's the whole vibe. 💅

---

🦋 SYNOPSIS 🦋

here's the shape of it, exactly as it is, no cap:

struct dmub_cmd_cursor_offload_init_data {
    union dmub_addr state_addr;
    uint32_t state_size;
 };

look at her. two members. main character energy. 👑

---

🧚 MEMBERS 🧚

so the page has a Members section and ngl… it's empty. like, nothing in there. a whole heading with no content. she said "I'm here" and then said nothing else. 😭

but the struct itself (up in the synopsis, you saw it) has these two, so you know what you're working with:

• union dmub_addr state_addr; — first member, exactly like it's spelled up there 💜
• uint32_t state_size; — second member, ditto 🫶

if you want the actual descriptions of those members, the manpage isn't giving them to us. we do not invent. we do not guess. we simply observe. 🔥

⭐ SEE ALSO ⭐

okay this is the part where the page goes absolutely feral and lists basically the entire dmub_cmd.h friend group. every single one. here we go, no skipping, bestie:

🍓 a lil sign-off 🍓

this page came out of the kernel source tree at ./drivers/gpu/drm/amd/display/..., and it's dated October 2026 in the footer — yes, the future, we don't ask questions — and the whole thing is served up as struct dmub_...ad_init_data(9) (the truncated name is not a typo bestie, that's genuinely how the footer renders it, and we are not fixing it). 🌈

go read dmub_cmd.h and slay. periodt. 👑💖
