chardev interface is needed for the user-space to share a region through mmap system call. This shared region will be used for user application like fio to allocate data so that when direct-IO operations are performed, the memory is already available inside the lcd. As direct-IO incurs no overhead of copying in the kernel, this makes sense for accessing data pointers that arrive inside bios without any copies inside the LCD.
