After some searching works, however, I barely find any reading material or tutorial about the details of using QEMU in kernel development, especially the driver development.

You can use the following command

$ qemu-system-x86_64
	-kernel arch/x86_64/boot/bzImage
	-append "root=/dev/sda console=ttyS0"

You can run this command from the root directory of whichever kernel
tree you are hacking on. I can't remember how I built/got the QEMU
image though. There are tutorials online about creating a QEMU image.

Hope this helps,
