🎀 get_subsampling(9) 🎀

okay bestie, welcome to the Kernel API Manual — this is the page for get_subsampling(9), and it's literally all about grabbing the subsampling divisor value on a specific direction. no cap. 💅

✨ NAME ✨

get_subsampling — get the subsampling divisor value on a specific direction ✨

🦋 SYNOPSIS 🦋

int get_subsampling (const struct drm_format_info *format , enum pixel_read_direction direction );

💅 ARGUMENTS 💅

• format — the format to extract the subsampling from. (the source page spells it extarct, and honestly? iconic 💀 but you know what it means.)
• direction — the direction of the subsampling requested, bestie. 🧚
