STRUCT IPU3_UAPI_RAD_FAR_W(9)
π struct ipu3_uapi_rad_far_w(9) β from the Kernel API Manual, bestie β¨
okay so you opened a manpage and it's literally a struct in the Kernel API Manual and it's giving "tiny but important" π this one is the Radial FAR sub-group, and yes it's as niche as it sounds but we're gonna slay it together π«Ά
πΈ NAME πΈ
struct ipu3_uapi_rad_far_w β the Radial FAR sub-group β¨ (that's the whole name, she's concise, we respect it π)
π¦ SYNOPSIS π¦
here's the whole vibe, character for character, don't touch anything:
struct ipu3_uapi_rad_far_w {
__u32 rad_dir_far_sharp_w:8;
__u32 rad_dir_far_dns_w:8;
__u32 rad_ndir_far_dns_power:8;
__u32 reserved:8;
};
four bitfields, 8 bits each, all cozy in one __u32. it's giving "small struct, big feelings" π
π Members π
rad_dir_far_sharp_wβ ngl bestie this is the weight of wide direct sharpening, formatted asu1.6, range[0, 64], and the default is64. so she comes out of the box at MAX crisp π₯ (u1.6 means you've got 6 fractional bits, iykyk)rad_dir_far_dns_wβ this one is the weight of wide direct denoising, alsou1.6, range[0, 64], but default0. so no denoising unless you ask for it πrad_ndir_far_dns_powerβ the power of non-direct sharpening (yes, sharpening, even though the field name says dns, that's literally what the page says, don't come for me π).u1.6, range[0, 64], default0.reservedβ reserved. that's it. that's the description. she's a mystery, we leave her alone π§
fr fr: keep an eye on those ranges β[0, 64]every single time, andu1.6every single time. the defaults are64,0,0, and then there's reserved doing absolutely nothing iconic π
