Basic run of s390x emulation on i386 also tested. Please ACK the series. Anthony, can you pull afterwards? The following changes since commit b5d54bd42158b90b239bb6ce9c13072eb3a53fd2: Merge remote-tracking branch 'qemu-kvm/uq/master' into stable-1.5 (2013-08-29 17:21:51 -0500) are available in the git repository at: git://github.com/borntraeger/qemu.git tags/kdump for you to fetch changes up to 7f7f975295bc19829b3bd26cadc7f1c9eadb7c6b: s390: wire up nmi command to raise a RESTART interrupt on S390 (2013-08-30 14:16:48 +0200) ---------------------------------------------------------------- This is a set of patches dealing with kdump support for s390x/kvm. kdump on s390x uses subcode 1 of diagnose 0x308 to put the hardware in a defined state. This is different from a full reset, since it does not touch all CPU registers. These patches define the cpu resets, the subsystem reset a load function and also wires up the "nmi" command to issue a RESTART interrupt as defined in the z/Architecture principles of operation. This allows recent guest kernels with properly setup userspace to trigger kdump: - via guest crash - via nmi from the host ---------------------------------------------------------------- Christian Borntraeger (5): s390x/kvm: Fix switch/case indentation for handle_diag s390: provide I/O subsystem reset s390: provide a cpu load normal function s390/cpu: split CPU reset into architectured functions s390: Implement load normal reset Eugene (jno) Dvurechenski (2): s390/kvm: basic implementation of diagnose 308 subcode 6 s390: wire up nmi command to raise a RESTART interrupt on S390 cpus.c | 14 ++++++++++ hmp-commands.hx | 4 +-- hw/s390x/s390-virtio-ccw.c | 15 ++++++++++ qmp-commands.hx | 2 +- target-s390x/cpu-qom.h | 6 ++++ target-s390x/cpu.c | 52 ++++++++++++++++++++++++++++++++-- target-s390x/cpu.h | 20 +++++++++++++ target-s390x/kvm.c | 40 +++++++++++++++++--------- target-s390x/misc_helper.c | 70 ++++++++++++++++++++++++++++++++++++++++++++++ 9 files changed, 204 insertions(+), 19 deletions(-)
