This is the first version to handle AP Interrupt using the GISA facility. The patch series is based on the GISA+GIB patch series sent by Michael Mueller. - We define a new VFIO ioctl to ask the vfio_ap driver to register a interruption for the guest. - We define the assembler code to register a GISA based interruption for the guest. - We register to the GIB Alert mechanism and suppress the GISA (firmware) based interrupts from the list of software handled interrupts. This patch series has been tested with success on z13 and z14 with adjunct processors CEX5[ACP] and CEX6C. To use, you, of course, need the QEMU patches, which will be sent separately.
