ENUM DRM_ETHOSU_BO_FLAGS(9)

💅 enum drm_ethosu_bo_flags(9) — the Kernel API Manual, but make it make sense 🎀

okay so bestie, this is a page from the Kernel API Manual and it's literally just a baby little enum. no cap, it's tiny, but it's important so pay attention 🫶

---

✨ NAME ✨

enum drm_ethosu_bo_flags — it's giving "buffer object flags, passed at creation time." that's the whole vibe 💖

---

🌸 SYNOPSIS 🌸

here's the whole thing, exactly as written, no edits, we respect the source:

enum drm_ethosu_bo_flags {
    DRM_ETHOSU_BO_NO_MMAP

};

yes bestie, there's exactly one (1) member in there. she's an icon, she's the main character 🌈

---

👑 Constants 👑

⭐ DRM_ETHOSU_BO_NO_MMAP

the whole meaning of this one: the buffer object will never be CPU-mapped in userspace.</italic> never ever. not once. periodt 💅

so like, if you're setting this flag, you're telling the kernel "bestie i promise i will not be mapping this thing to the CPU from userspace," and it takes you at your word 🔥

ngl this page is short but she ate. one flag, zero filler, maximum clarity 💯

and that's a wrap! this lil gem lives in ./include/uapi/drm, it's dated October 2026, and its manual name is enum drm_ethosu_bo_flags(9). bye bestie, go forth and don't CPU-map that buffer 💜🧚✨
