STRUCT DRM_VC4_LABEL_BO(9)

💅 struct drm_vc4_label_bo(9) 💅

okay bestie, welcome to the Kernel API Manual — yes that's the manual name, we're fancy here ✨ — and today's main character is struct drm_vc4_label_bo. Buckle up, it's short but it's iconic.

---

🌸 NAME 🌸

struct drm_vc4_label_bo — literally just "Attach a name to a BO for debug purposes." That's the whole job. That's the assignment. No cap 💅

✨ SYNOPSIS ✨

struct drm_vc4_label_bo {
    __u32 handle;
    __u32 len;
    __u64 name;
 };

okay so it's giving very minimal, very demure. three fields. that's it. type them exactly like that, bestie, down to the underscores on __u32 and __u64 🫶

🎀 Members 🎀

so this page has a Members section and then… nothing in it 😭 not a single member description. the struct's fields are listed up in the synopsis — handle, len, and name — but ngl this manpage is not spilling the tea on what each one does individually. so I'm not gonna invent lore for you. we keep it honest in this group chat 💀

fr fr: no member descriptions are given here. if you need them, the SEE ALSO crew below is your next stop.

🦋 SEE ALSO 🦋

bestie the cross-references ATE, look at this list:

• the kernel file ./include/uapi/drm/vc4_drm.h — that's the source of truth, the mothership, the origin story 👑
• struct drm_vc4_submit_cl(9)
• struct drm_vc4_wait_seqno(9)
• struct drm_vc4_wait_bo(9)
• struct drm_vc4_create_bo(9)
• struct drm_vc4_mmap_bo(9)
• struct drm_vc4_create_shader_bo(9)

like, that's a whole friend group right there 💜 go say hi to each of them, they all have their own pages.

💡 a tiny vibe check: this whole struct exists for debug purposes — the name says "label", the description says "for debug purposes", the math is mathing. don't go treating it like a production API, iykyk 🧚

mwah, that's a wrap! 🍓 this lil beauty lives in ./include/uapi/drm, and the version tag on it is October 2026 — so yes, a future queen 💅 mark your calendars, screenshot it, put it on the fridge. slay, periodt. 🌈⭐
