STRUCT RKISP1_STAT_BUFFER(9)

💅 struct rkisp1_stat_buffer(9) 💅

okay bestie so this page comes straight out of the Kernel API Manual and it's all about struct rkisp1_stat_buffer — the Rockchip ISP1 Statistics Meta Data situation ✨ it is literally the little envelope your image signal processor uses to hand you back "here's what I saw this frame" receipts. it's giving behind-the-scenes main character energy 🎀

🌸 NAME 🌸

struct rkisp1_stat_buffer — Rockchip ISP1 Statistics Meta Data 💖

🦋 SYNOPSIS 🦋

struct rkisp1_stat_buffer {
    __u32 meas_type;
    __u32 frame_id;
    struct rkisp1_cif_isp_stat params;
 };

👑 Members 👑

• meas_type — the measurement types, and yes it's the RKISP1_CIF_ISP_STAT_* definitions holding it down. this field is the "what are we even measuring rn" of it all 💫
• frame_id — the frame ID, there purely for sync. so you can match your stats back to the exact frame they belong to, no cap 🫶
• params — the statistics data itself. the actual payload, the reason we're all here 🙈

ngl bestie, this page is a reference and nothing more — it documents the struct, its three members and where it lives. no flags, no defaults, no exit codes to memorize here, you're safe 🫶

and that's a wrap! this cutie came to you from the source path ./include/uapi/linux and it's dated October 2026, filed under the struct rkisp1_stat_buffer(9) header. mwah 💋✨ stay slay, go read your stats 🦋🌸
