STRUCT IPU3_UAPI_AWB_FR_CONFIG_S(9)

💖 NAME 💖

struct ipu3_uapi_awb_fr_config_s — AWB filter response config. That's the name, bestie, and it's serving exactly that. periodt. ✨

Also hi, welcome to the struct ipu3_..._fr_config_s(9) page from the Kernel API Manual — yes, that's the manual-name vibe folded in right here. 🫶

✨ SYNOPSIS ✨

okay so the struct itself is literally this, and yes, copy it exactly because we do not freestyle kernel definitions in this group chat 💅:

struct ipu3_uapi_awb_fr_config_s {
    struct ipu3_uapi_grid_config grid_cfg;
    __u8 bayer_coeff[6];
    __u16 reserved1;
    __u32 bayer_sign;
    __u8 bayer_nf;
    __u8 reserved2[7];
 };

• grid_cfg — grid config, default 16x16. That's the whole vibe.
• bayer_coeff — 1D Filter 1x11 center symmetry/anti-symmetry. the coefficients default to { 0, 0, 0, 0, 0, 128 }. Applied on whole image for each Bayer channel separately by a weighted sum of its 11x1 neighbors. obsessed with the specificity, ngl.
• reserved1 — reserved. no notes. literally reserved. 💅
• bayer_sign — sign of filter coefficients, default 0.
• bayer_nf — normalization factor for the convolution coeffs, to make sure total memory needed is within pre-determined range. NF should be the log2 of the sum of the abs values of the filter coeffs, range [7, 14], default 7. highkey important, lowkey iconic. 🎀
• reserved2 — reserved. also reserved, matching energy. 🦋
