STRUCT MTK_MDP_CTX(9)

✨ NAME ✨

okay so bestie, this is the manual page for struct mtk_mdp_ctx — literally the device context data structure, from the Kernel API Manual. it's giving "the main character data structure for MediaTek MDP" energy 💅

🌸 SYNOPSIS 🌸

struct mtk_mdp_ctx {
    struct list_head                list;
    struct mtk_mdp_frame            s_frame;
    struct mtk_mdp_frame            d_frame;
    u32 flags;
    u32 state;
    int id;
    int rotation;
    u32 hflip:1;
    u32 vflip:1;
    struct mtk_mdp_dev              *mdp_dev;
    struct v4l2_m2m_ctx             *m2m_ctx;
    struct v4l2_fh                  fh;
    struct v4l2_ctrl_handler        ctrl_handler;
    struct mtk_mdp_ctrls            ctrls;
    bool ctrls_rdy;
    enum v4l2_colorspace            colorspace;
    enum v4l2_ycbcr_encoding        ycbcr_enc;
    enum v4l2_xfer_func             xfer_func;
    enum v4l2_quantization          quant;
    struct mtk_mdp_vpu              vpu;
    struct mutex                    slock;
    struct work_struct              work;
 };

💅 MEMBERS 💅

okay so here's the full breakdown of every single member, no skips, periodt:

• list — links this context into the ctx_list of mtk_mdp_dev. it's literally the group chat of contexts 💬
• s_frame — the source frame properties. where the pixels are coming from, iykyk 🫶
• d_frame — the destination frame properties. where the pixels are going to ✨
• flags — extra flags for image conversion. little toggles that change how the conversion works 🎀
• state — flags that keep track of the user configuration. protected by slock 🔒
• id — the index of the context that this structure describes. its little name tag 🏷️
• rotation — rotates the image by the specified angle. spin that pic, bestie 🔄
• hflip — mirrors the picture horizontally. left-right flip, iconic 🪞
• vflip — mirrors the picture vertically. upside-down moment 🙃
• mdp_dev — the image processor device this context applies to. the actual hardware bestie 🖥️
• m2m_ctx — the memory-to-memory device context. the m2m squad rep 💾
• fh — the v4l2 file handle. v4l2's little handle for this context 📎
• ctrl_handler — the v4l2 controls handler. manages the controls, no cap 🎛️
• ctrls — the image processor control set. all the knobs and sliders in one place 🌈
• ctrls_rdy — true if the control handler is initialized. a little boolean vibe check ✅
• colorspace — an enum v4l2_colorspace; supplemental to pixelformat. the color space vibe 🎨
• ycbcr_enc — an enum v4l2_ycbcr_encoding, the Y'CbCr encoding. chroma encoding bestie 🧚
• xfer_func — an enum v4l2_xfer_func, the colorspace transfer function. how colors get transferred, literally 💫
• quant — an enum v4l2_quantization, the colorspace quantization. quantization queen 👑
• vpu — the VPU instance. video processing unit, slay ⚡
• slock — the mutex protecting mtp_mdp_ctx.state. (yes, the original says mtp, not mtk — that's how it's written, so that's how i'm keeping it 🫡). lock it down so nothing gets messy 🔐
• work — the worker for image processing. gets the actual processing done in the background 💪
