Hi,
this is the QEMU companion patchset to "vfio-ccw: support for {halt,clear} subchannel", but is interface-wise independent of it.
With an old host kernel, things should work as before. With a new host kernel, guest halt/clear requests should get passed through to the host.
I tested this with a hacked-up guest kernel to issue clears on demand.
Cornelia Huck (2): vfio-ccw: forward halt/clear to device if supported s390/css: add some tracing for pass-through handling
