STRUCT OMAP3ISP_H3A_AEWB_CONFIG(9)

💅 NAME

ok so this is struct omap3isp_h3a_aewb_config — the AE AWB configuration reset values, bestie ✨ (AE = auto exposure, AWB = auto white balance, in case you were wondering, and yes we're being that girl rn).

Also tagging along in here: saturation_limit: Saturation limit. — yeah it literally shows up in the NAME section too, don't ask, that's just how this page rolls 🎀

This whole thing lives in the Kernel API Manual, section 9, if you're keeping track 🦋

🌸 SYNOPSIS

struct omap3isp_h3a_aewb_config {
    __u32 buf_size;
    __u16 config_counter;
    __u16 saturation_limit;
    __u16 win_height;
    __u16 win_width;
    __u16 ver_win_count;
    __u16 hor_win_count;
    __u16 ver_win_start;
    __u16 hor_win_start;
    __u16 blk_ver_win_start;
    __u16 blk_win_height;
    __u16 subsample_ver_inc;
    __u16 subsample_hor_inc;
    __u8 alaw_enable;
};

like, look at her. one __u32, a whole parade of __u16s, and one tiny __u8 at the end serving main character energy 👑

✨ Members ✨

okay so here's the roster, and honestly the ranges are giving "very specific for a reason" so pls respect them 🙏

• win_height — Window Height. Range 2 - 256, even values only. (odd numbers? not invited. blocked. 💀)
• win_width — Window Width. Range 6 - 256, even values only. (note the 6, not 2 — she's different, she's iconic)
• ver_win_count — Vertical Window Count. Range 1 - 128.
• hor_win_count — Horizontal Window Count. Range 1 - 36.
• ver_win_start — Vertical Window Start. Range 0 - 4095.
• hor_win_start — Horizontal Window Start. Range 0 - 4095.
• blk_ver_win_start — Black Vertical Windows Start. Range 0 - 4095.
• blk_win_height — Black Window Height. Range 2 - 256, even values only. (same even-only rule, no cap 🫶)
• subsample_ver_inc — Subsample Vertical points increment. Range 2 - 32, even values only.
• subsample_hor_inc — Subsample Horizontal points increment. Range 2 - 32, even values only.
• alaw_enable — AEW ALAW EN flag. 🚩

lowkey a heads up bestie: buf_size, config_counter and saturation_limit are in the struct up there in the SYNOPSIS but this page doesn't spell out ranges for them. saturation_limit gets its one-liner in NAME and that's literally it. don't come for me, that's just what the page says 💀
