Realize VFIO_DEVICE_GET_IRQ_INFO ioctl to retrieve VFIO_CCW_IO_IRQ information. Realize VFIO_DEVICE_SET_IRQS ioctl to set an eventfd fd for VFIO_CCW_IO_IRQ. Once a write operation to the ccw_io_region was performed, trigger a signal on this fd.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
