Subject: [PATCH 0/6] target/i386: Support new Intel platform Instructions in CPUID enumeration
Date: Thu, 8 Dec 2022 15:19:11 +0800 [thread overview]
Message-ID: <20221208071917.1923093-1-jiaxi.chen@linux.intel.com> (raw)
Latest Intel platform Granite Rapids/Sierra Forest has introduced below
new instructions and CPUIDs:
- CMPccXADD CPUID.(EAX=7,ECX=1):EAX[bit 7]
- AMX-FP16 CPUID.(EAX=7,ECX=1):EAX[bit 21]
- AVX-IFMA CPUID.(EAX=7,ECX=1):EAX[bit 23]
- AVX-VNNI-INT8 CPUID.(EAX=7,ECX=1):EDX[bit 4]
- AVX-NE-CONVERT CPUID.(EAX=7,ECX=1):EDX[bit 5]
- PREFETCHITI CPUID.(EAX=7,ECX=1):EDX[bit 14]
Details can be found in recent Intel ISE (Instruction Set Extensions)[1].
Linux 6.2 will support for advertising these features to userspace. KVM
patches have been merged into kvm/next[2]. This patch series adds CPUID
definitions of the corresponding features in QEMU.
