STRUCT IPU3_UAPI_STATS_3A(9)

🎀 NAME 🎀

struct ipu3_uapi_stats_3a — bestie, this is the 3A statistics struct, and yes it's from the Kernel API Manual, welcome to the group chat 💖

---

✨ SYNOPSIS ✨

okay so here's the whole vibe, literally copy this exactly:

struct ipu3_uapi_stats_3a {
    struct ipu3_uapi_awb_raw_buffer awb_raw_buffer;
    struct ipu3_uapi_ae_raw_buffer_aligned ae_raw_buffer[IPU3_UAPI_MAX_STRIPES];
    struct ipu3_uapi_af_raw_buffer af_raw_buffer;
    struct ipu3_uapi_awb_fr_raw_buffer awb_fr_raw_buffer;
    struct ipu3_uapi_4a_config stats_4a_config;
    __u32 ae_join_buffers;
    __u8 padding[28];
    struct ipu3_uapi_stats_3a_bubble_info_per_stripe stats_3a_bubble_per_stripe;
    struct ipu3_uapi_ff_status stats_3a_status;
 };

🌸 DESCRIPTION 🌸

💅 Members 💅

• awb_raw_buffer — the auto white balance meta data, typed ipu3_uapi_awb_raw_buffer. she's the moment, honestly 🫶
• ae_raw_buffer — auto exposure raw data, ipu3_uapi_ae_raw_buffer_aligned. ⚠️ but heads up bestie: current Imgu does not output the auto exposure statistics to ae_raw_buffer, so the user — like a 3A algorithm — can use the RGB table in ipu3_uapi_awb_raw_buffer to do auto-exposure instead. lowkey iconic workaround ngl 💅
• af_raw_buffer — ipu3_uapi_af_raw_buffer for auto focus meta data 🔥
• awb_fr_raw_buffer — value as specified by ipu3_uapi_awb_fr_raw_buffer ✨
• stats_4a_config — the 4a statistics config, as defined by ipu3_uapi_4a_config 🎀
• ae_join_buffers — 1 to use ae_raw_buffer. just 1. that's the whole thing 🦋
• padding — padding config, doing her little __u8 thing, 28 of them, no notes 💀
• stats_3a_bubble_per_stripe — a ipu3_uapi_stats_3a_bubble_info_per_stripe, yes that's the actual name, i didn't make it up 😭
• stats_3a_status — 3a statistics status, set in ipu3_uapi_ff_status 👑
