* s390x/cpumodel: Set up CPU model for AP device supportTony Krowiak2018-10-121-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A new CPU model feature and two new CPU model facilities are introduced to support AP devices for a KVM guest. CPU model features: 1. The S390_FEAT_AP CPU model feature indicates whether AP instructions are available to the guest. This feature will be enabled only if the AP instructions are available on the linux host as determined by the availability of the KVM_S390_VM_CRYPTO_ENABLE_APIE VM attribute which is exposed by KVM only if the AP instructions are available on the host. This feature must be turned on from userspace to execute AP instructions on the KVM guest. The QEMU command line to turn this feature on looks something like this: qemu-system-s390x ... -cpu xxx,ap=on ... This feature will be supported for zEC12 and newer CPU models. The feature will not be supported for older models because there are few older systems on which to test and the older crypto cards will be going out of service in the relatively near future. CPU model facilities: 1. The S390_FEAT_AP_QUERY_CONFIG_INFO feature indicates whether the AP Query Configuration Information (QCI) facility is available to the guest as determined by whether the facility is available on the host. This feature will be exposed by KVM only if the QCI facility is installed on the host. 2. The S390_FEAT_AP_FACILITY_TEST feature indicates whether the AP Facility Test (APFT) facility is available to the guest as determined by whether the facility is available on the host. This feature will be exposed by KVM only if APFT is installed on the host.

* s390x/cpumodel: model PTFF subfunctions for Multiple-epoch facilityDavid Hildenbrand2018-02-091-0/+4
| | | | | | | | | | | | | | | For now, the kernel does not properly indicate configured CPU subfunctions to the guest, but simply uses the host values (as support in KVM is still missing). That's why we missed to model the PTFF subfunctions that come with Multiple-epoch facility. Let's properly add these, along with a new feature group.

* s390x/cpumodel: add zpci, aen and ais facilitiesYi Min Zhao2017-07-141-0/+3
| | | | | | | | | | | | | | | | | 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.

* Move target-* CPU file into a target/ folderThomas Huth2016-12-201-0/+231
We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.
