[Qemu-devel] [PATCH 0/7v3] s390: sclp patch set


From: Christian Borntraeger
Subject: [Qemu-devel] [PATCH 0/7v3] s390: sclp patch set
Date: Tue, 24 Jul 2012 09:37:03 +0200

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.

Thanks
