2017-06-06s390x/cpumodel: improve defintion search without an IBCDavid Hildenbrand
Currently, under z/VM on a 0x2827, QEMU will detect a 0x2828 if no IBC value is provided. QEMU will simply take the last model of that HW generation, which happens to be the BC version. Let's improve our search for that case by selecting the latest CPU definition that matches the CPU type. This for example will avoid detecting an z13 as a z13s. We might still detect a GA2 version on a GA1 system, but as we don't have further information at hand, there isn't too much we can do about it. The alternative of always presenting the oldest GA is not backward compatible, e.g: You're running on 0x2827 GA2. Old QEMU version indicated "0x2828 GA1 == 0x2827 GA2". After you updated QEMU, you suddenly detect "0x2827 GA1". You're previous libvirt guest might suddenly refuse to run. In the end presenting a newer GA level does not matter because: 1: All GAX models share the same base feature set. A GAX++ might support "more features". 2: Without an IBC, the guest can't detect the GA version. If we have no IBC (esp. unblocked_ibc == 0), the IBC we will present to the guest in read_SCP_info() will be 0. The guest will not know which GA version it has. The problem of missing IBC propagates. If we don't have a feature of the GA++ version, also our guest won't have it. So in summary, the guest also has no idea of its GA version.

2017-06-06s390x/cpumodel: take care of the cpuid format bit for KVMDavid Hildenbrand
Let's also properly forward that bit. It should always be set. I verified it under z/VM, it seems to be always set there. For now, zKVM guests never get that bit set when the CPU model is active. The PoP mentiones, that z800 + z900 (HW generation 7) always set this bit to 0, so let's take care of that.

2017-05-23shutdown: Add source information to SHUTDOWN and RESETEric Blake
Time to wire up all the call sites that request a shutdown or reset to use the enum added in the previous patch. It would have been less churn to keep the common case with no arguments as meaning guest-triggered, and only modified the host-triggered code paths, via a wrapper function, but then we'd still have to audit that I didn't miss any host-triggered spots; changing the signature forces us to double-check that I correctly categorized all callers. Since command line options can change whether a guest reset request causes an actual reset vs. a shutdown, it's easy to also add the information to reset requests.

2017-05-19s390x/css: add s390-squash-mcss machine optionXiao Feng Ren
We want to support real (i.e. not virtual) channel devices even for guests that do not support MCSS-E (where guests may see devices from any channel subsystem image at once). As all virtio-ccw devices are in css 0xfe (and show up in the default css 0 for guests not activating MCSS-E), we need an option to squash both the virtio subchannels and e.g. passed-through subchannels from their real css (0-3, or 0 for hosts not activating MCSS-E) into the default css. This will be exploited in a later patch.
