STRUCT RPMSG_CTRLDEV(9)

🌸 NAME 🌸

okay so bestie, this is struct rpmsg_ctrldev(9), straight from the Kernel API Manual, and it is the control device for instantiating endpoint devices. That's the whole assignment: ctrl-device structure, endpoint-device instantiating energy, no cap. 💅

✨ SYNOPSIS ✨

       struct rpmsg_ctrldev {
           struct rpmsg_device *rpdev;
           struct cdev cdev;
           struct device dev;
           struct mutex ctrl_lock;
        };

👑 Members 👑

• rpdev — the underlaying rpmsg device. Yes, that's the word on the page, and we're keeping it exactly. 🫶
• cdev — the cdev for the ctrl device. It's literally the cdev for the ctrl device, periodt.
• dev — the device for the ctrl device. Main-character struct device energy for the ctrl device. ✨
• ctrl_lock — serialize the ioctrls. One at a time, bestie — no ioctl chaos. 🔒
