STRUCT VPU_RUN(9)

💜 struct vpu_run(9) — like, the whole manual page, bestie

okay so quick vibe check: this is a page from the Kernel API Manual, and it's all about struct vpu_run — yes, the VPU initialization status king itself 👑✨ grab a strawberry 🍓 and let's get into it.

---

🌸 NAME 🌸

struct vpu_run — literally the VPU initialization status. that's it, that's the whole thing 💅

---

✨ SYNOPSIS ✨

struct vpu_run {
    u32 signaled;
    char fw_ver[VPU_FW_VER_LEN];
    unsigned int    dec_capability;
    unsigned int    enc_capability;
    wait_queue_head_t wq;
 };

no cap, that's the exact struct, character for character, don't @ me 🙈

---

🎀 Members 🎀

• signaled — the signal of vpu initialization completed. basically the little "we're so back" flag 🚩
• fw_ver — VPU firmware version. the firmware's whole identity, stored in a char array of length VPU_FW_VER_LEN 🦋
• dec_capability — decoder capability which is not used for now and the value is reserved for future use. so like... it's giving placeholder main character energy 😭 it's not doing anything yet, it's just vibing there reserved for the future
• enc_capability — encoder capability which is not used for now and the value is reserved for future use. same situation fr fr, also reserved for future use, also not used for now 🫶
• wq — wait queue for VPU initialization status. the actual wait_queue_head_t where everyone waits around for the init status to show up ⏳

lowkey note: dec_capability and enc_capability are both not used for now and their values are reserved for future use — so don't go building your whole personality around them yet bestie 💀

okay that's the whole page, you understood it perfectly, I'm so proud of you 🧚💖

sign-off time: this came from ./drivers/media/platform/media..., dated October 2026, and it's the struct vpu_run(9) page. periodt. 🎀✨
