of the user space system call to Linux. Most character device drivers implement the Read (), write (), and IOCTL () functions.1 struct file_operations xxx_fops =2 {3 . Owner = this_module,4 . Read = xxx_read,5 . write = xxx_write,6 . IOCTL = Xxx_ioctl,7 ... 8 };The following is an explanation of the character device driver based on the virtual Globalmem device. Globalmem means "global memory", where the Globalmem character device driver allocates a space of globalmem_ size, and provides read-
