STRUCT C3_ISP_AE_STATS(9)

💅 struct c3_isp_ae_stats(9) — the Kernel API Manual glow-up ✨

okay so bestie, buckle up — this is struct c3_isp_ae_stats, straight out of the Kernel API Manual, and it's literally the blueprint for Exposure statistics information. ngl, it's giving main character energy in the auto-exposure world 🎀

---

✨ NAME ✨

struct c3_isp_ae_stats — Exposure statistics information. that's it, that's the vibe 🫶

---

🌸 SYNOPSIS 🌸

struct c3_isp_ae_stats {
    struct c3_isp_ae_zone_stats stats[C3_ISP_AE_MAX_ZONES];
    __u32 reserved[2];
    __u32 hist[1024];
 };

like, look at her. she's compact, she's iconic, she's a whole struct. 💜

---

🦋 Members 🦋

• stats — the array of auto exposure block statistics. every zone pulls up with its own stats, fr fr 👑
• reserved — undefined buffer space. do not touch, do not ask, it's just chillin' 🙈
• hist — a 1024-bin histogram for the entire image. yes, all 1024 bins, no skimping 💀✨

---

🌈 Description 🌈

so the AE statistical information is made up of all blocks information and a 1024-bin histogram. that's the whole tea ☕ — blocks on blocks on blocks, plus the histogram doing its thing for the whole image. lowkey elegant, highkey essential. 💅

bestie if you're implementing against this, please please PLEASE leave reserved alone — it's undefined buffer space and it will not hesitate to ruin your day 😭

okay that's the page!! 💖 this one lives at ./include/uapi/linux/media/aml... (yeah the path got cut off, iykyk) and it's dated October 2026 — so like, future-core but make it kernel. slay, bye! 🧚‍♀️⭐🍓
