39 ./hw/goldfish_pipe.c implements the virtual driver.
49 drivers/misc/qemupipe/qemu_pipe.c contains the driver source code
56 The device and driver use an I/O memory page and an IRQ to communicate.
58 - The driver writes to various I/O registers to send commands to the
61 - The device raises an IRQ to instruct the driver that certain events
64 - The driver reads I/O registers to get the status of its latest command,
