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.
