Most of the patches here are from Tao Su's v1. The main issue in his version were two:
- overlooking kvm_cpu_xsave_init(), which currently looks at ExtSaveArea. This would get a bit ugly for extended save states that are enabled by both AVX512 and AVX10. Patches 1-2 change kvm_cpu_xsave_init() to look at ExtSaveArea's size field instead of testing features. - downgrading silently to KVM reported value if the avx10_version property is >= kvm reported value. Xiaoyao Li suggested basing this on cpu->check_cpuid and cpu->enforce_cpuid. Also, the check must accept any accelerator and not just KVM. I moved the check to x86_cpu_filter_features in patch 4. I don't have a Granite Rapids machine, so please test! :) Paolo Paolo Bonzini (3): target/i386: cpu: set correct supported XCR0 features for TCG target/i386: do not rely on ExtSaveArea for accelerator-supported XCR0 bits target/i386: return bool from x86_cpu_filter_features Tao Su (5): target/i386: add AVX10 feature and AVX10 version property target/i386: add CPUID.24 features for AVX10 target/i386: Add feature dependencies for AVX10 target/i386: Add AVX512 state when AVX10 is supported target/i386: Introduce GraniteRapids-v2 model target/i386/cpu.h | 16 ++++ target/i386/cpu.c | 175 ++++++++++++++++++++++++++++++++++---- target/i386/kvm/kvm-cpu.c | 8 -- target/i386/kvm/kvm.c | 3 +- 4 files changed, 175 insertions(+), 27 deletions(-) -- 2.47.0
