STRUCT RKISP1_CIF_ISP_LSC_CONFIG(9)

💖 struct rkisp1_cif_isp_lsc_config (9) 💖

okay so bestie, welcome to the Kernel API Manual — yes, that's the manual name, and yes, we're reading kernel headers together like it's a group chat at 2am 🫶 this one's a struct, it lives in ./include/uapi/linux/rkisp1-config.h, and it is literally the configuration used by Lens shading correction. lens shading?? like when your camera pic is dark in the corners and the vibes are uneven?? yeah, this struct is the fix. iconic behavior honestly 💅

✨ NAME ✨

struct rkisp1_cif_isp_lsc_config — the configuration used by Lens shading correction. that's it, that's the whole name section, she's concise 💖

🦋 SYNOPSIS 🦋

struct rkisp1_cif_isp_lsc_config {
    __u16
r_data_tbl[RKISP1_CIF_ISP_LSC_SAMPLES_MAX][RKISP1_CIF_ISP_LSC_SAMPLES_MAX];
    __u16
gr_data_tbl[RKISP1_CIF_ISP_LSC_SAMPLES_MAX][RKISP1_CIF_ISP_LSC_SAMPLES_MAX];
    __u16
gb_data_tbl[RKISP1_CIF_ISP_LSC_SAMPLES_MAX][RKISP1_CIF_ISP_LSC_SAMPLES_MAX];
    __u16
b_data_tbl[RKISP1_CIF_ISP_LSC_SAMPLES_MAX][RKISP1_CIF_ISP_LSC_SAMPLES_MAX];
    __u16 x_grad_tbl[RKISP1_CIF_ISP_LSC_SECTORS_TBL_SIZE];
    __u16 y_grad_tbl[RKISP1_CIF_ISP_LSC_SECTORS_TBL_SIZE];
    __u16 x_size_tbl[RKISP1_CIF_ISP_LSC_SECTORS_TBL_SIZE];
    __u16 y_size_tbl[RKISP1_CIF_ISP_LSC_SECTORS_TBL_SIZE];
    __u16 config_width;
    __u16 config_height;
 };

look at her. ten members. all __u16. no cap, every single one is an unsigned 16-bit lil guy 🌸

🎀 Members 🎀

the glow-up tour, field by field, no skipping, we do not skip in this house ✨

• r_data_tbl — sample table red. that's the red samples, bestie 🔴
• gr_data_tbl — sample table green (red). green-red, iykyk 🟢
• gb_data_tbl — sample table green (blue). green-blue, the other green 🟢
• b_data_tbl — sample table blue. blue samples, blue like your fave's text bubbles 🔵
• x_grad_tbl — gradient table x. the gradient, but horizontal 💫
• y_grad_tbl — gradient table y. the gradient, but vertical 💫
• x_size_tbl — size table x. horizontal sizes, queen of widths 👑
• y_size_tbl — size table y. vertical sizes, equally queen 👑
• config_width — not used at the moment. she's sitting there, being decorative, we respect her anyway 🙈
• config_height — not used at the moment. matching energy, also decorative, also respected 🙈

lowkey the four *_data_tbl ones are [RKISP1_CIF_ISP_LSC_SAMPLES_MAX][RKISP1_CIF_ISP_LSC_SAMPLES_MAX] — that's a 2D table, not a vibe, an entire grid, and the four x_grad_tbl / y_grad_tbl / x_size_tbl / y_size_tbl ones are [RKISP1_CIF_ISP_LSC_SECTORS_TBL_SIZE]. keep those macros exactly as-is, do not touch, they are not decorative 💀

not me reading that entire list out loud like a roll call 💀 but every single one of them is in the index, no cap, no omissions, we ate 🔥
