drm_format_...v_semiplanar(9)

💖 drm_format_info_is_yuv_semiplanar(9) — the NAME section, bestie

okay so this is a page from the Kernel API Manual, section 9, and the page itself is called drm_format_...v_semiplanar(9) (yes the title got truncated by the manpage formatter, it's giving cursed filename energy, we move). 💅

🌸 NAME

drm_format_info_is_yuv_semiplanar — the little function that checks whether a format info actually matches a YUV format with data laid in two planes (that's luminance and chrominance, iykyk ✨).

✨ SYNOPSIS ✨

bool drm_format_info_is_yuv_semiplanar (const struct drm_format_info
*info );

lowkey the whole vibe in one line: you hand it format info, it hands you back a bool. 🫶

🎀 ARGUMENTS

• info — the format info. that's it, that's the argument. one (1) bestie coming in. 💖

🔥 RETURN

A boolean indicating whether the format info matches a semiplanar YUV format. so like… yes or no. true if it's giving semiplanar YUV, false if it is not. no cap, that's the whole return value situation. ⭐

💀 reminder bestie: this page is about checking the format info, not mutating anything. it returns a bool and goes home. don't be weird about it. 🙈
