Subject: [PATCH 36/38] target/i386: Add AVX512 state when AVX10 is supported
|
|
|
|
RH-Author: Paolo Bonzini <pbonzini@redhat.com>
|
|
RH-MergeRequest: 280: Add support for the AVX10.1, SHA512, SM3 and SM4 instruction sets

RH-Commit: [7/9] 6f791fae9a3255140795b709435b25159226becf (bonzini/rhel-qemu-kvm)
|
|
|
|
AVX10 state enumeration in CPUID leaf D and enabling in XCR0 register
|
|
are identical to AVX512 state regardless of the supported vector lengths.
|
|
|
|
Given that some E-cores will support AVX10 but not support AVX512, add
|
|
AVX512 state components to guest when AVX10 is enabled.
