STRUCT GSC_M2M_DEVICE(9)

💅 STRUCT GSC_M2M_DEVICE(9) ✨

okay so bestie, welcome to the struct gsc_m2m_device page, straight out of the Kernel API Manual, section 9 — yes, that's the kernel section, we're fancy here 🎀

---

🌸 NAME 🌸

struct gsc_m2m_device — the v4l2 memory-to-memory device data, aka the little struct that holds all the m2m vibes 🦋

---

✨ SYNOPSIS ✨

here's the whole glow-up, character for character, no edits (we don't do that here):

struct gsc_m2m_device {
    struct video_device     *vfd;
    struct v4l2_m2m_dev     *m2m_dev;
    struct gsc_ctx          *ctx;
    int refcnt;
 };

🫶 MEMBERS 🫶

every field is a main character, let's meet them:

• vfd — the video device node for v4l2 m2m mode. this is the actual node bestie, the thing userspace talks to 💖
• m2m_dev — v4l2 memory-to-memory device data. literally the m2m core's own data, held right here 🔥
• ctx — hardware context data. the hardware's own context situation, living its life 🧚
• refcnt — the reference counter. keeping track of who's holding on, no cap ⭐
