STRUCT FIMC_CTX(9)

💖 struct_fimc_ctx(9) 💖

okay so bestie, welcome to the Kernel API Manual — specifically the page for struct fimc_ctx, and honestly? it's giving "the whole vibe of one camera pipeline, packaged into a single C struct." no cap. this is the device context data, and it's a lot, so grab a strawberry drink 🍓 and let's go through it field by field. i promise i'll keep it readable 💅

✨ NAME ✨

struct fimc_ctx — the device context data

like, the entire context blob for a device. one struct, all the state. iconic behavior honestly 👑

---

🌸 SYNOPSIS 🌸

struct fimc_ctx {
    struct fimc_frame       s_frame;
    struct fimc_frame       d_frame;
    u32 out_order_1p;
    u32 out_order_2p;
    u32 in_order_1p;
    u32 in_order_2p;
    enum fimc_datapath      in_path;
    enum fimc_datapath      out_path;
    struct fimc_scaler      scaler;
    struct fimc_effect      effect;
    int rotation;
    unsigned int            hflip:1;
    unsigned int            vflip:1;
    u32 flags;
    u32 state;
    struct fimc_dev         *fimc_dev;
    struct v4l2_fh          fh;
    struct fimc_ctrls       ctrls;
 };

look at her. twenty lines of pure main character energy. let's break down every single member because we do NOT skip 💀

🎀 Members 🎀

• s_frame — source frame properties. the "before" picture, literally ✨
• d_frame — destination frame properties. the "after" picture, the glow-up 🦋
• out_order_1p — output 1-plane YCBCR order
• out_order_2p — output 2-plane YCBCR order
• in_order_1p — input 1-plane YCBCR order
• in_order_2p — input 2-plane YCBCR order

(note how the 1p/2p pairs are just matching sets, in and out. they're twins. they're the moment. anyway 💅)

• in_path — input mode (DMA or camera)
• out_path — output mode (DMA or FIFO)
• scaler — image scaler properties. she resizes, she serves 💁‍♀️
• effect — image effect
• rotation — image clockwise rotation in degrees. clockwise ONLY, bestie, don't @ me 🙈
• hflip — indicates image horizontal flip if set
• vflip — indicates image vertical flip if set
• flags — additional flags for image conversion
• state — flags to keep track of user configuration. lowkey the struct's little diary of what you've configured 📓
• fimc_dev — the FIMC device this context applies to. her home. her origin story 🏠
• fh — v4l2 file handle
• ctrls — v4l2 controls structure

fr fr, that's every single member — nothing skipped, nothing merged, that's the whole roster 🫶

<s>and that's the whole page, periodt.</s> no wait — one more thing 🧚

this lil masterpiece comes from ./drivers/media/platform/samsu... and it's dated October 2026, so like... future-coded of it, honestly ⭐ thank you for coming to my ted talk, go configure something pretty 💖🌈
