STRUCT GSC_FMT(9)

🎀 struct gsc_fmt(9) 🎀

okay so bestie, welcome to the Kernel API Manual ✨ — this little page is all about struct gsc_fmt, which is literally the driver's own internal color format data. no cap, it's the glow-up blueprint the driver keeps for itself 💅

---

💖 NAME 💖

struct gsc_fmt — the driver's internal color format data 🎨🦋

---

✨ SYNOPSIS ✨

here's the whole struct, character for character, don't touch a thing:

struct gsc_fmt {
    u32 mbus_code;
    u32 pixelformat;
    u32 color;
    u32 yorder;
    u32 corder;
    u16 num_planes;
    u16 num_comp;
    u8 depth[VIDEO_MAX_PLANES];
    u32 flags;
 };

like… she's giving main character energy, honestly 👑

🌸 Members 🌸

okay so let's meet the cast, one field at a time 🫶

• mbus_code — the Media Bus pixel code 🎀. it's -1 if it's not applicable, so if you see -1 just know she's sitting this one out.
• pixelformat — the fourcc code for this format, and it's 0 if not applicable 🙈.
• color — the color encoding 🌈.
• yorder — the Y/C order ⭐.
• corder — the Chrominance order control 🎚️.
• num_planes — how many data planes are physically non-contiguous (yes, the scattered girlies) 💀.
• num_comp — how many data planes are physically contiguous 🧚.
• depth — per-plane, a driver's private "number of bits per pixel" 👑. it's an array, VIDEO_MAX_PLANES of them, so it's per plane, iykyk.
• flags — the flags saying which operation mode this format applies to 🚩.
