💅 get_convers..._to_argb_u16(9) 💅

Okay bestie, welcome to the Kernel API Manual page for get_convers..._to_argb_u16(9) — yes, the header abbreviates it like that, and yes, the full name is spelled out below. This one is lowkey iconic: it retrieves the correct yuv to rgb conversion matrix for a given encoding and range. That's the whole plot. 🎀

✨ NAME ✨

get_conversion_matrix_to_argb_u16 — retrieve the correct yuv to rgb conversion matrix for a given encoding and range. Slay. 💖

✨ SYNOPSIS ✨

Here's the signature, copied exactly so nobody comes for me:

void get_conversion_matrix_to_argb_u16 (u32 format , enum
       drm_color_encoding encoding , enum drm_color_range range , struct
       conversion_matrix *matrix );

🎀 ARGUMENTS 🎀

• format — a DRM_FORMAT_* value, and it's the one you're obtaining a conversion function for (see [drm_fourcc.h]). Go peep the header if you need the format lore. 🦋
• encoding — a DRM_COLOR_* value; this is what you're obtaining a conversion matrix for. ✨
• range — a DRM_COLOR_*_RANGE value; also for obtaining that conversion matrix. 🌸
• matrix — pointer to store the value into. That's the storage spot, bestie. 📥
