STRUCT IPU3_UAPI_UNSHARP_COEF0(9)
πΈ NAME πΈ
struct ipu3_uapi_unsharp_coef0 β the unsharp mask coefficients, bestie. Yeah, that's literally it. This is a page from the Kernel API Manual.
β¨ SYNOPSIS β¨
okay so here's the whole struct, exactly as it lives, no cap:
struct ipu3_uapi_unsharp_coef0 {
__u32 c00:9;
__u32 c01:9;
__u32 c02:9;
__u32 reserved:5;
};
look at those bitfields. nine bits, nine bits, nine bits, five reserved. it's giving packed. π

c00β Coeff11, s0.8, range[-255, 255], default1. yes that's the default, it's a whole 1, iconic.c01β Coeff12, s0.8, range[-255, 255], default5. five. that's the vibe.c02β Coeff13, s0.8, range[-255, 255], default9. nine, main character energy honestly.reservedβ reserved π«Ά (leave it alone, it's reserved, that's the whole personality)
π¦ Description π¦
Configurable registers for common sharpening support. that's the whole description. short and slay. it's the coefficient registers the unsharp mask uses, and they're configurable, periodt. β¨
