STRUCT RKISP1_EXT_PARAMS_COMPAND_CURVE_CONFIG(9)
π NAME
struct rkisp1_ext_params_compand_curve_config β the RkISP1 extensible params Compand curve config, bestie. That's the whole vibe, no cap β¨
So like, quick context: the manual this lives in is the Kernel API Manual (yes, the big one), and this page is literally just about one struct. One. Struct. And it's iconic. π
β¨ SYNOPSIS β¨
struct rkisp1_ext_params_compand_curve_config {
struct rkisp1_ext_params_block_header header;
struct rkisp1_cif_isp_compand_curve_config config;
};
That's it, that's the whole shape of it. Two members, zero drama π¦
π«Ά MEMBERS π«Ά
headerβ the RkISP1 extensible parameters header, k? It's the little intro card that every block carries around. Seerkisp1_ext_params_block_header. πconfigβ the actual Companding curve configuration, i.e. the good stuff. Seerkisp1_cif_isp_compand_curve_config. π
πΈ DESCRIPTION πΈ
Okay so this struct is the RkISP1 extensible parameters Companding configuration block β and before you ask, yes, it's hiding both the expand curve and the compression curve in there. Two curves, one block, main character energy fr fr π
How do you know which flavor you got? It gets ID'd by one of these two block types:
RKISP1_EXT_PARAMS_BLOCK_TYPE_COMPAND_EXPANDRKISP1_EXT_PARAMS_BLOCK_TYPE_COMPAND_COMPRESS
That's the vibe check for compand blocks, iykyk. β¨

Literally the whole family tree, ngl β go read these too, they're all linked from Kernel file ./include/uapi/linux/rkisp1-config.h π¦

π real talk: that's a lot of SEE ALSO. But like, you clicked on the compand curve page, so respectfullyβ¦ you're already in this deep. Slay. π
okay bye bestie, go configure some curves π
