STRUCT MTK_JPEGDEC_COMP_DEV(9)

✨ struct mtk_jpegdec_comp_dev(9) ✨

okay so bestie, welcome to the Kernel API Manual — this is the page for struct mtk_jpegdec_comp_dev, and we're gonna get you so comfy with it 💖

---

🌸 NAME 🌸

struct mtk_jpegdec_comp_dev — JPEG COREX abstraction 🎀

---

🦋 SYNOPSIS 🦋

struct mtk_jpegdec_comp_dev {
    struct device *dev;
    struct platform_device *plat_dev;
    void __iomem *reg_base;
    struct mtk_jpeg_dev *master_dev;
    struct mtk_jpegdec_clk jdec_clk;
    int jpegdec_irq;
    struct delayed_work job_timeout_work;
    struct mtk_jpeg_hw_param hw_param;
    enum mtk_jpeg_hw_state hw_state;
    spinlock_t hw_lock;
 };

like, that's the whole shape of it. no cap, just read it top to bottom and it lowkey starts making sense 👑

💅 Members 💅

okay this is the part where we go member by member, bestie — every single one, no skipping 🙈

• dev — the JPEG device ✨
• plat_dev — the platform device data 🌈
• reg_base — the JPEG registers mapping, i.e. where the registers live in memory 💖
• master_dev — the mtk_jpeg_dev device 👑
• jdec_clk — an mtk_jpegdec_clk 🎀
• jpegdec_irq — the jpeg decode irq num 🔥
• job_timeout_work — the decode timeout workqueue ⏰ (she's a struct delayed_work, very demure)
• hw_param — the jpeg decode hw parameters 🧚
• hw_state — records the hw state ⭐
• hw_lock — a spinlock protecting hw 🔒 literally the bouncer at the club

🌟 SEE ALSO 🌟

go look at the kernel file ./drivers/media/platform/mediatek/jpeg/mtk_jpeg_core.h, plus the enum mtk_jpeg_ctx_state(9) — and the whole friend group is here too, bestie 🫶:

• struct mtk_jpeg_variant(9)
• struct mtk_jpegenc_clk(9)
• struct mtk_jpegdec_clk(9)
• struct mtk_jpegenc_comp_dev(9)
• struct mtk_jpeg_dev(9)
• struct mtk_jpeg_fmt(9)
• struct mtk_jpeg_q_data(9)
• struct mtk_jpeg_ctx(9)

💀 reminder: hw_lock is a spinlock protecting hw — that's its whole job, so don't be weird about it, okay?
