STRUCT RPPX1_WBMEAS_STATS(9)

💅 struct rppx1_wbmeas_stats(9) — the AWB statistics one 🎀

okay bestie, so this is a page from the Kernel API Manual, and it's all about struct rppx1_wbmeas_stats, which is lowkey just… AWB statistics. Auto white balance tea. ✨ Let's get into it.

✨ SYNOPSIS ✨

struct rppx1_wbmeas_stats {
    struct v4l2_isp_block_header header;
    __u32 cnt;
    __u32 mean_y_or_g;
    __u32 mean_cb_or_b;
    __u32 mean_cr_or_r;
 };

that's the whole struct, no cap. five fields and we're done. 🫶

🌸 MEMBERS 🌸

• header — the block header, and its type is RPPX1_STATS_BLOCK_TYPE_WBMEAS_POST 👑 that's literally the whole vibe of this field.
• cnt — how many pixels matched. the headcount, the attendance list, the "who showed up" number 💀
• mean_y_or_g — the mean Y value, or the mean G value if you're in RGB mode. it's a 24-bit number. so in RGB mode it's giving G, otherwise it's giving Y. iykyk 💜
• mean_cb_or_b — the mean Cb value, or the mean B value if RGB mode is on. also 24-bit. yes bestie, the naming is doing that thing where it lists both lives 🦋
• mean_cr_or_r — the mean Cr value, or the mean R value when you're in RGB mode. 24-bit again. three little means, all matching the same energy 🌈

so many friends, omg. this struct does NOT exist in a vacuum, bestie. go say hi to:
