s390x/cpumodel: Set up CPU model for AP device support 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.

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: Add new TCG features to QEMU cpu model We now implement a bunch of new facilities we can properly indicate. ESOP-1/ESOP-2 handling is discussed in the PoP Chafter 3-15 ("Suppression on Protection"). The "Basic suppression-on-protection (SOP) facility" is a core part of z/Architecture without a facility indication. ESOP-2 is indicated by ESOP-1 + Side-effect facility ("ESOP-2"). Besides ESOP-2, the side-effect facility is only relevant for the guarded-storage facility (we don't implement). S390_ESOP: - We indicate DAT exeptions by setting bit 61 of the TEID (TEC) to 1 and bit 60 to zero. We don't trigger ALCP exceptions yet. Also, we set bit 0-51 and bit 62/63 to the right values. S390_ACCESS_EXCEPTION_FS_INDICATION: - The TEID (TEC) properly indicates in bit 52/53 on any access if it was a fetch or a store S390_SIDE_EFFECT_ACCESS_ESOP2: - We have no side-effect accesses (esp., we don't implement the guarded-storage faciliy), we correctly set bit 64 of the TEID (TEC) to 0 (no side-effect). - ESOP2: We properly set bit 56, 60, 61 in the TEID (TEC) to indicate the type of protection. We don't trigger KCP/ALCP exceptions yet. S390_INSTRUCTION_EXEC_PROT: - The MMU properly detects and indicates the exception on instruction fetches - Protected TLB entries will never get PAGE_EXEC set. There is no need to fake the abscence of any of the facilities - without the facilities, some bits of the TEID (TEC) are simply unpredictable. As IEP was added with z14 and we currently implement a z13, add it to the MAX model instead. Acked-by: Cornelia Huck <cohuck@redhat.com> Signed-off-by: David Hildenbrand <david@redhat.com>
