Paolo Bonzini f751d8eac1 KVM: x86: work around QEMU issue with synthetic CPUID leaves ... Synthesizing AMD leaves up to 0x80000021 caused problems with QEMU, which assumes the *host* CPUID[0x80000000].EAX is higher or equal to what KVM_GET_SUPPORTED_CPUID reports. This causes QEMU to issue bogus host CPUIDs when preparing the input to KVM_SET_CPUID2. It can even get into an infinite loop, which is only terminated by an abort(): cpuid_data is full, no space for cpuid(eax:0x8000001d,ecx:0x3e) To work around this, only synthesize those leaves if 0x8000001d exists on the host. The synthetic 0x80000021 leaf is mostly useful on Zen2, which satisfies the condition.
