STRUCT VPU_WDT(9)

💅 struct vpu_wdt(9) 💅

okay so bestie, welcome to the Kernel API Manual — yes, the whole manual, we're living large today. this little page is all about struct vpu_wdt, aka the VPU watchdog workqueue. it's giving "the thing that watches the watcher" and honestly? iconic. 🫶

---

✨ NAME ✨

struct vpu_wdt — the VPU watchdog workqueue. that's it, that's the vibe. 🎀

---

🌸 SYNOPSIS 🌸

here's the whole struct, bestie, character for character, don't @ me:

struct vpu_wdt {
    struct vpu_wdt_handler handler[VPU_RST_MAX];
    struct work_struct ws;
    struct workqueue_struct *wq;
 };

look at her. three members. no cap, that's the whole thing. ✨

🦋 MEMBERS 🦋

so like, let's go member by member, because every single one matters:

• handler — the VPU watchdog reset handler 💅 — and note it's an array of VPU_RST_MAX of them, because we're thorough in this house.
• ws — the work_struct for the VPU watchdog. this is the workstruct, working hard so you don't have to. 🔥
• wq — the workqueue for the VPU watchdog. it's a workqueue_struct *, so yes, it's a pointer, and yes, it's main character energy. 👑

🌈 SEE ALSO 🌈

go read these next, bestie, they're all connected, iykyk:

• the kernel file ./drivers/media/platform/mediatek/vpu/mtk_vpu.c — that's the source file, fr fr
• enum vpu_fw_type(9)
• struct vpu_mem(9)
• struct vpu_regs(9)
• struct vpu_wdt_handler(9)
• struct vpu_run(9)
• struct vpu_ipi_desc(9)
• struct share_obj(9)
• struct mtk_vpu(9)

like a little friend group. all of them. go say hi. 💖

🧚 sign-off 🧚

this page came from ./drivers/media/platform/mediatek/vpu/mtk_vpu.c (yes, the path got squished in the original footer too, we keep it real), and it's dated October 2026. slay. ⭐

anyway ily, go read a struct, drink some water, and remember: the watchdog is watching 💀🌸
