STRUCT BDISP_DEV(9)

✨ struct bdisp_dev(9) ✨

okay bestie, welcome to the Kernel API Manual 💖 this one's all about struct bdisp_dev — the whole vibe of it is literally just abstraction for bdisp entity, no cap. that's the NAME section, we ate it up, moving on 🫶

---

🌸 SYNOPSIS 🌸

here's the whole struct, character for character, do NOT touch it, she's perfect:

struct bdisp_dev {
    struct v4l2_device      v4l2_dev;
    struct video_device     vdev;
    struct platform_device  *pdev;
    struct device           *dev;
    spinlock_t slock;
    struct mutex            lock;
    u16 id;
    struct bdisp_m2m_device m2m;
    unsigned long           state;
    struct clk              *clock;
    void __iomem            *regs;
    wait_queue_head_t irq_queue;
    struct workqueue_struct *work_queue;
    struct delayed_work     timeout_work;
    struct bdisp_dbg        dbg;
};

like, look at her. main character struct energy fr fr 👑

💅 Members 💅

every single one, in order, no skips, we don't do that here:

• v4l2_dev — the v4l2 device 💜
• vdev — the video device 🎀
• pdev — the platform device 🌸
• dev — the device 🦋
• slock — a spinlock whose whole job is protecting this data structure 🔥
• lock — a mutex, also protecting this data structure (yes, both. two protectors. iconique) ✨
• id — the device index 🔢
• m2m — memory-to-memory V4L2 device information 🌈
• state — flags used to synchronize m2m and capture mode operation ⭐
• clock — the IP clock ⏰
• regs — the registers 🗂️
• irq_queue — the interrupt handler waitqueue 😴
• work_queue — workqueue used to handle timeouts ⏳
• timeout_work — the IRQ timeout structure 💀
• dbg — debug info 🔍

• struct bdisp_request(9)
• struct bdisp_ctx(9)
• struct bdisp_m2m_device(9)
• struct bdisp_dbg(9)

ok that's the whole page, nothing skipped, nothing invented, we kept every flag and every field exactly as written 💖

so this little love letter came out of ./drivers/media/platform/st/st... and it's dated October 2026 — yeah, the future. she's ahead of her time. periodt 🍓👑
