2017-07-14s390x/kvm: enable guarded storageFan Zhang
Introduce guarded storage support for KVM guests on s390. We need to enable the capability, extend machine check validity, sigp store-additional-status-at-address, and migration. The feature is fenced for older machine type versions.

2017-07-14s390x/cpumodel: we are always in zarchitecture modeJason J. Herne
In QEMU, a guest VCPU always started in and never was able to leave z/Architecture mode. Now we have an architected way of showing this condition. The SIGP SET ARCHITECTURE instruction is simply rejected. Linux as guest seems to not care about the return value, which is a good thing The new handling is just like already being in z/Architecture mode. We'll not try to fake absence of this facility, but still not indicate the facility in case some strange CPU model turned z/Architecture off completely (which doesn't work either way but let's us see how a guest would react on a lack of this facility).

2017-07-14s390x/cpumodel: add zpci, aen and ais facilitiesYi Min Zhao
zPCI instructions and facilities are available since IBM zEnterprise EC12. To support z/PCI in QEMU we enable zpci, aen and ais facilities starting with zEC12 GA1. And we always set zpci and aen bits in max cpu model. Later they might be switched off due to applied real cpu model. For ais bit, we only provide it in the full cpu model beginning with zEC12 and defer its enablement in the default cpu model to a later point in time. At the same time, disable them for 2.9 and older machines. Because of introducing AIS facility, we could check if it's enabled to initialize flic->ais_supported with the real value.

2017-07-14pc-bios/s390: add s390-netboot.imgChristian Borntraeger
It's already possible to do a network boot of an s390x guest with an external netboot image based on a Linux installation, but it would be much more convenient if the s390-ccw firmware supported network booting right out of the box, without the need to assemble such an external image first. This is an s390-netboot.img that can be used for network booting. You can download a combined kernel + initrd image via TFTP by starting QEMU for example with: qemu-system-s390x ... -device virtio-net,netdev=n1,bootindex=1 \ -netdev user,id=n1,tftp=/path/to/tftp,bootfile=kernel.img Note that this version does not support downloading via config files (i.e. pxelinux config files or .INS config files) yet.

2017-07-14s390x: add css_migration_enabled to machine classHalil Pasic
Currently the migration of the channel subsystem (css) is only partial and is done by the virtio ccw proxies -- the only migratable css devices existing at the moment. With the current work on emulated and passthrough devices we need to decouple the migration of the channel subsystem state from virtio ccw, and have a separate section for it. A new section however necessarily breaks the migration compatibility. So let us introduce a switch at the machine class, and put it in 'off' state for now. We will turn the switch 'on' for future machines once all preparations are met. For compatibility machines the switch will stay 'off'.

2017-07-14s390x/flic: introduce modify_ais_mode callbackFei Li
In order to emulate the adapter interruption suppression (AIS) facility properly, the guest needs to be able to modify the AIS mask. Interrupt suppression will be handled via the flic (for kvm, via a recently introduced kernel backend; for !kvm, in the flic code), so let's introduce a method to change the mode via the flic interface. We introduce the 'simm' and 'nimm' fields to QEMUS390FLICState to store interruption modes for each ISC. Each bit in 'simm' and 'nimm' targets one ISC, and collaboratively indicate three modes: ALL-Interruptions, SINGLE-Interruption and NO-Interruptions. This interface can initiate most transitions between the states; transition from SINGLE-Interruption to NO-Interruptions via adapter interrupt injection will be introduced in a following patch. The meaningful combinations are as follows: interruption mode | simm bit | nimm bit ------------------|----------|---------- ALL | 0 | 0 SINGLE | 1 | 0 NO | 1 | 1 Co-authored-by: Yi Min Zhao <zyimin@linux.vnet.ibm.com> Signed-off-by: Yi Min Zhao <zyimin@linux.vnet.ibm.com> Signed-off-by: Fei Li <sherrylf@linux.vnet.ibm.com> Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com>

2017-07-12scripts: use build_ prefix for string not piped through cgen()Marc-André Lureau
The gen_ prefix is awkward. Generated C should go through cgen() exactly once (see commit 1f9a7a1). The common way to get this wrong is passing a foo=gen_foo() keyword argument to mcgen(). I'd like us to adopt a naming convention where gen_ means "something that's been piped through cgen(), and thus must not be passed to cgen() or mcgen()". Requires renaming gen_params(), gen_marshal_proto() and gen_event_send_proto().

2017-07-12qobject: Update coccinelle script to catch Q{INC, DEC}REFEric Blake
The recent commit b097efc0 used qobject_decref(QOBJECT(E)), even though we already have QDECREF(E) for that purpose. We can update our coccinelle script to catch any future relapses; with that in place, the rest of the patch is generated with: spatch --sp-file scripts/coccinelle/qobject.cocci \ --macro-file scripts/cocci-macro-file.h --dir . --in-place Signed-off-by: Eric Blake <eblake@redhat.com> Message-Id: <20170624181008.25497-3-eblake@redhat.com> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Markus Armbruster <armbru@redhat.com>
2017-07-12qobject: Catch another straggler for use of qdict_put_str()Eric Blake
Dan's addition of key-secret improvements in commit 29cf9336 was developed prior to the addition of QDict scalar insertion macros, but merged after the general cleanup in commit 46f5ac20.
