STRUCT IPU3_UAPI_YUVP1_CHNR_CONFIG(9)
πΈ struct ipu3_uapi_yuvp1_chnr_config (9) β like, the Kernel API Manual page you actually want to read π
okay so bestie, welcome to the Kernel API Manual β¨ and to one (1) struct that handles chroma noise reduction config π for the Intel IPU3. it's giving "small struct, four whole vibes inside". no cap, let's go π
β¨ NAME β¨
struct ipu3_uapi_yuvp1_chnr_config β Chroma noise reduction config π
like literally, that's the whole thing. it's the config package for chroma noise reduction, and it holds four sub-configs inside it like lil matryoshka dolls πͺ
π¦ SYNOPSIS π¦
here's the shape of it, exactly as it lives, copy it byte for byte please π
struct ipu3_uapi_yuvp1_chnr_config {
struct ipu3_uapi_yuvp1_chnr_enable_config enable;
struct ipu3_uapi_yuvp1_chnr_coring_config coring;
struct ipu3_uapi_yuvp1_chnr_sense_gain_config sense_gain;
struct ipu3_uapi_yuvp1_chnr_iir_fir_config iir_fir;
};
four members, all structs, all doing their own little main-character thing π«
π Members π
π enable
chroma noise reduction enable β see ipu3_uapi_yuvp1_chnr_enable_config. it's the on/off of it all, the vibe check of the whole struct, ykwim? π«Ά
π coring
coring config for chroma noise reduction β see ipu3_uapi_yuvp1_chnr_coring_config. the coring. the config. the coring config. iconic of it π
πΈ sense_gain
sensitivity config for chroma noise reduction β see ipu3_uapi_yuvp1_chnr_sense_gain_config. it's the sensitivity era, and honestly? slay β¨
π§ iir_fir
iir and fir config for chroma noise reduction β see ipu3_uapi_yuvp1_chnr_iir_fir_config. two filters, one member, zero notes π₯
fr fr bestie, each of these four points at its own doc page β tap in on those if you want the full lore, because this page is just the container π
π SEE ALSO π
okay this is the part where I hold up the entire friend group π every single one of these, no skips, no cuts:
- the Kernel file
./drivers/staging/media/ipu3/include/uapi/intel-ipu3.hβ the source of truth, go say hi π
