STRUCT AMDXDNA_DRM_GET_BO_INFO(9)

💅 struct amdxdna_drm_get_bo_info — Kernel API Manual, but make it make sense

okay so bestie, welcome to the kernel API manual for struct amdxdna_drm_get_bo_info. Yes that's a long name, yes it's the whole vibe, no we are not abbreviating it. 🎀

---

✨ NAME ✨

struct amdxdna_drm_get_bo_info — literally just here to Get buffer object information. That's it. That's the whole job. 🫶

---

🦋 SYNOPSIS 🦋

struct amdxdna_drm_get_bo_info {
    __u64 ext;
    __u64 ext_flags;
    __u32 handle;
    __u32 pad;
    __u64 map_offset;
    __u64 vaddr;
    __u64 xdna_addr;
 };

look at her. seven fields, all accounted for, no notes. 💜

🌸 Members 🌸

okay so let's go field by field, iykyk:

• ext — MBZ. that's it, that's the entry. do not put anything in there, she said what she said 💀
• ext_flags — MBZ too. icon behaviour honestly, zero obligations ✨
• handle — the DRM buffer object handle. like the little name tag your buffer wears at the party 🎀
• pad — MBZ. padding, must be zero, minding its own business 🙈
• map_offset — returned DRM fake offset for mmap. yes "fake", no that's not shady, that's just what it's called, we don't ask questions 💅
• vaddr — returned user VA of the buffer. and here's the tea: it's 0 in case the user needs mmap. so if you see a zero, that's your cue, bestie 😭
• xdna_addr — returned XDNA device virtual address. the actual device-side address, returned, slaying 🔥

ngl the MBZ fields are MBZ. all three of them. don't get creative, it's not the moment 👑
