RH-Author: Paolo Bonzini <pbonzini@redhat.com>

RH-MergeRequest: 391: TDX support, including attestation and device assignment

RH-Commit: [2/115] 58b986eab9ccc86b3f50ca480ae184779cd85bee (bonzini/rhel-qemu-kvm)
|
|
|
|
- CPUID.(EAX=07H,ECX=0H):EBX[bit 6]: x87 FPU Data Pointer updated only
|
|
on x87 exceptions if 1.
|
|
|
|
- CPUID.(EAX=07H,ECX=0H):EBX[bit 13]: Deprecates FPU CS and FPU DS
|
|
values if 1. i.e., X87 FCS and FDS are always zero.
|
|
|
|
Define names for them so that they can be exposed to guest with -cpu host.
|
|
|
|
Also define the bit field MACROs so that named cpu models can add it as
|
|
well in the future.
