This patch-set improves the Service-Call Logical Processor support for s390. This version addresses comments from Blueswirl and Andreas Färber.
Patch 1 is a bugfix for the current code, dealing with error and condition code handling. Patch 2 introduces a new file under target-s390 which will provide floating interrupt support. Patch 3 adds/changes some base SCLP support. Patch 4 adds code to support the SCLP commands Write Event Mask, Write Event Data, and Read Event Data. Patch 5 and 6 add code to implement the commands for the particular SCLP events Signal Quiesce (system_powerdown), and ASCII Console data. Patch 7 (s390: make sclp ascii console the default) is currently optional as it requires a kernel fix in the guest (http://git.kernel.org/?p=virt/kvm/kvm.git;a=commit;h=cd1834591fe9564720ac4b0193bf1c790fe89f0d KVM: s390: Perform early event mask processing during boot) For testing patches 6 and 7 on older kernels the kernel command line console=ttyS1 can be used.
