There are certain features that we put into base models, but that are not relevant for the actual search. The most famous example are MSA subfunctions that might be disabled on certain real hardware out there. While the kvm host model detection will usually detect the correct model on such machines (as it will in the common case not pass features to check for into s390_find_cpu_def()), baselining will fall back to a quite old model just because some MSA subfunctions are missing. Let's improve that by ignoring lack of these features while performing the search for a base model.

The SIE_KSS feature will allow a guest to use KSS for a nested guest. To create a nested guest the SIE_F2 facility is still necessary. Since SIE_F2 is not part of the default model it does not make a lot of sense to provide the SIE_KSS feature in the default model. Let's also create a dependency check.

STFL bit 4 and 5 are just indications to the guest, which TLB entries an IDTE call will clear. These are performance indicators for the guest. STFL bit 4: INVALIDATE DAT TABLE ENTRY (IDTE) performs the invalidation-and-clearing operation by selectively clearing TLB segment-table entries when a segment-table entry or entries are invalidated. IDTE also performs the clearing-by- ASCE operation. Unless bit 4 is one, IDTE simply purges all TLBs. Bit 3 is one if bit 4 is one. We can simply set STFL bit 4 ("idtes") and still purge the complete TLB. Purging more than advertised is never bad. E.g. Linux doesn't even care about this bit. We can optimized this later. This is helpful, as the z9 base model contains this facility. STFL bit 5 (clearing TLB region-table-entries) was never implemented on real HW, therefore we can simply ignore it for now.

The response for query-cpu-definitions didn't include the unavailable-features field, which is used by libvirt to figure out whether a certain cpu model is usable on the host. The unavailable features are now computed by obtaining the host CPU model and comparing it against the known CPU models. The comparison takes into account the generation, the GA level and the feature bitmaps. In the case of a CPU generation/GA level mismatch a feature called "type" is reported to be missing. As a result, the output of virsh domcapabilities would change from something like ... <mode name='custom' supported='yes'> <model usable='unknown'>z10EC-base</model> <model usable='unknown'>z9EC-base</model> <model usable='unknown'>z196.2-base</model> <model usable='unknown'>z900-base</model> <model usable='unknown'>z990</model> ... to ... <mode name='custom' supported='yes'> <model usable='yes'>z10EC-base</model> <model usable='yes'>z9EC-base</model> <model usable='no'>z196.2-base</model> <model usable='yes'>z900-base</model> <model usable='yes'>z990</model> ...

This adds support for the MOVE WITH OPTIONAL SPECIFICATIONS (MVCOS) instruction. Allow to enable it for the qemu cpu model using qemu-system-s390x ... -cpu qemu,mvcos=on ... This allows to boot linux kernel that uses it for uacccess. We are missing (as for most other part) low address protection checks, PSW key / storage key checks and support for AR-mode. We fake an ADDRESSING exception when called from problem state (which seems to rely on PSW key checks to be in place) and if AR-mode is used. user mode will always see a PRIVILEDGED exception.

Let's properly expose the CPU type (machine-type number) via "STORE CPU ID" and "STORE SUBSYSTEM INFORMATION". As TCG emulates basic mode, the CPU identification number has the format "Annnnn", whereby A is the CPU address, and n are parts of the CPU serial number (0 for us for now). A specification exception will be injected if the address is not aligned to a double word. Low address protection will not be checked as we're missing some more general support for that.

Currently we only present the plain z900 feature bits to the guest, but QEMU already emulates some additional features (but not all of the next CPU generation, so we can not use the next CPU level as default yet). Since newer Linux kernels are checking the feature bits and refuse to work if a required feature is missing, it would be nice to have a way to present more of the supported features when we are running with the "qemu" CPU. This patch now adds the supported features to the "full_feat" bitmap, so that additional features can be enabled on the command line now, for example with: qemu-system-s390x -cpu qemu,stfle=true,ldisp=true,eimm=true,stckf=true Acked-by: NDavid Hildenbrand <david@redhat.com> Reviewed-by: NAurelien Jarno <aurelien@aurel32.net> Signed-off-by: NThomas Huth <thuth@redhat.com> Message-Id: <1495704132-5675-1-git-send-email-thuth@redhat.com> Signed-off-by: NRichard Henderson <rth@twiddle.net>

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.

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.

We have to test if a configured CPU model is runnable in the current configuration, and if not report why that is the case. This is done by comparing it to the maximum supported model (host for KVM or z900 for TCG). Also, we want to do some base sanity checking for a configured CPU model. We'll cache the maximum model and the applied model (for performance reasons and because KVM can only be configured before any VCPU is created). For unavailable "host" model, we have to make sure that we inform KVM, so it can do some compatibility stuff (enable CMMA later on to be precise).
