Kirill A. Shutemov 7ae15e2f69 x86/tdx: Enable CPU topology enumeration ... TDX 1.0 defines baseline behaviour of TDX guest platform. TDX 1.0 generates a #VE when accessing topology-related CPUID leafs (0xB and 0x1F) and the X2APIC_APICID MSR. The kernel returns all zeros on CPUID topology. In practice, this means that the kernel can only boot with a plain topology. Any complications will cause problems. The ENUM_TOPOLOGY feature allows the VMM to provide topology information to the guest. Enabling the feature eliminates topology-related #VEs: the TDX module virtualizes accesses to the CPUID leafs and the MSR. Enable ENUM_TOPOLOGY if it is available. Signed-off-by: Kirill A.
