STRUCT S5P_JPEG_FMT(9)

💅 NAME

struct s5p_jpeg_fmt — bestie, this is the driver's own internal lil' dossier on a color format 🎀 like it's the receipts the s5p-jpeg driver keeps on every pixel layout it fucks with.

This page lives in the Kernel API Manual, section 9 (iykyk, that's the kernel-API girlies) ✨

🌸 SYNOPSIS

struct s5p_jpeg_fmt {
    u32 fourcc;
    int depth;
    int colplanes;
    int memplanes;
    int h_align;
    int v_align;
    int subsampling;
    u32 flags;
 };

That's the whole vibe, no cap — eight fields, one iconic little struct 🫶

💖 MEMBERS

okay so let's go through the whole cast, one by one, main character energy only:

• fourcc — the fourcc code, fr fr. And if it's 0? That means it's not applicable, so don't come for it 💀
• depth — how many bits per pixel. literally just the bit count, that's the whole thing 🌈
• colplanes — the number of color planes. packed formats? that's 1, periodt 💅
• memplanes — the number of memory planes. also 1 for the packed formats, she's consistent ✨
• h_align — horizontal alignment order. so you align to 2^h_align, okay? the exponent is doing the work here, not the raw number 👑
• v_align — vertical alignment order, same situation: you align to 2^v_align. twin to h_align but vertical, we love a matched set 🦋
• subsampling — the subsampling of a raw format or a JPEG. yes it does both, she contains multitudes 🌸
• flags — the flags that describe the format's applicability. ie: what this format is actually good for 🎀

lowkey a whole squad, ngl. go read 'em all, they're short 🫶

okay that's the page!! sourced straight from ./drivers/media/platform/samsung/s5p-jpeg/jpeg-core.h, dated October 2026, and yes the footer was giving struct s5p_jpeg_fmt(9) 💜 mwah, go forth and encode ✨🧚
