[Qemu-devel] [PATCH for-2.1 v1 1/3] qdev: Define qdev_get_gpio_out

[Peter Crosthwaite]

An API similar to the existing qdev_get_gpio_in() except gets outputs.
Useful for testing or debugging code which may wish to override the
hardware generated value of of a GPIO with a user specified value
(E.G. interrupt injection).
