STRUCT IPU3_UAPI_BNR_STATIC_CONFIG_LUT_CONFIG(9)

🎀 NAME 🎀

okay bestie, welcome to the struct ipu3_uapi_bnr_static_config_lut_config(9) page from the Kernel API Manual. This struct is the BNR square root lookup table, and it is literally here to hold that LUT. periodt.

✨ SYNOPSIS ✨

struct ipu3_uapi_bnr_static_config_lut_config {
    __u8 values[IPU3_UAPI_BNR_LUT_SIZE];
};

🫶 Members 🫶

• values — the pre-calculated values of the square root function. That is the whole member, no cap.

🌸 Description 🌸

This is the LUT implementation of the square root operation. like, it is the lookup-table way of doing square-root duties, and that is iconic behavior.

🌈 SEE ALSO 🌈

the whole kernel friend group is linked here, bestie — every single one:
