We tried to make pci support optional on s390x in the past; unfortunately, we still require the s390 phb to be created unconditionally due to backwards compatibility issues. Instead of sinking more effort into this (including compat handling for older machines etc.) for non-obvious gains, let's just make CONFIG_PCI something that is always set on s390x. Note that you can still fence off pci for the _guest_ if you provide a cpu model without the zpci feature.

The previous patch moved virtual css bridge and bus out from virtio-ccw, but kept the direct reference of virtio-ccw specific unplug function inside css-bridge.c. To make the virtual css bus and bridge useful for non-virtio devices, this introduces a common unplug function pointer "unplug" to call specific virtio-ccw unplug parts. Thus, the tight coupling to virtio-ccw can be removed. This unplug pointer is a member of CCWDeviceClass, which is introduced as an abstract device layer called "ccw-device". This layer is between DeviceState and specific devices which are plugged in virtual css bus, like virtio-ccw device. The specific unplug handlers should be assigned to "unplug" during initialization.

Currently, common base layers virtual css bridge and bus are defined in hw/s390x/virtio-ccw.c(h). In order to support multiple types of devices in the virtual channel subsystem, especially non virtio-ccw, refactoring work needs to be done. This work is just a pure code move without any functional change except dropping an empty function virtual_css_bridge_init() and virtio_ccw_busdev_unplug() changing. virtio_ccw_busdev_unplug() is specific to virtio-ccw but gets referenced from the common virtual css bridge code. To keep the functional changes to a minimum we export this function from virtio-ccw.c and continue to reference it inside virtual_css_bridge_class_init() (now living in hw/s390x/css-bridge.c). A follow-up patch will clean this up.

This code adds console support by implementing SCLP's ASCII Console Data event. This is the same console as LPARs ASCII console or z/VMs sysascii. The console can be specified manually with something like -chardev stdio,id=charconsole0 -device sclpconsole,chardev=charconsole0,id=console0 Newer kernels will autodetect that console and prefer that over virtio console. When data is received from the character layer it creates a service interrupt to trigger a Read Event Data command from the guest that will pick up the received character byte-stream. When characters are echo'ed by the linux guest a Write Event Data occurs which is forwarded by the Event Facility to the console that supports a corresponding mask value. Console resizing is not supported. The character layer byte-stream is buffered using a fixed size iov buffer.
