STRUCT IPU3_UAPI_AE_RAW_BUFFER(9)

💖 NAME 💖

struct ipu3_uapi_ae_raw_buffer — the AE global weighted histogram, bestie ✨ (this is from the Kernel API Manual, and yes we're getting into it)

---

🌸 SYNOPSIS 🌸

struct ipu3_uapi_ae_raw_buffer {
    __u32 vals[IPU3_UAPI_AE_BINS * IPU3_UAPI_AE_COLORS];
 };

okay so it's literally just one array, one struct, and honestly? she's lowkey iconic for that 🎀

---

🎀 Members 🎀

• vals — the sum of IPU3_UAPI_AE_COLORS in cell, fr fr 🫶

---

🦋 DESCRIPTION 🦋

so the way this works: every histogram contains IPU3_UAPI_AE_BINS bins 👑 and each bin holds a 24 bit unsigned value, which is what's counting the number of the pixel. that's it, that's the vibe 💅

ngl, that's the whole description. tiny struct, huge main character energy 🌟

✨ SEE ALSO ✨

the kernel file lives right here, bestie: ./drivers/staging/media/ipu3/include/uapi/intel-ipu3.h 📂

and because she's that girl, here's the full squad of neighbours — literally all of them, no skips, no cuts 😭💜
