Subject: [PATCH 0/2] x86: cater for CPUID leaf 7 subleaf 1
Date: Fri, 17 May 2019 06:21:01 -0600 [thread overview]
Message-ID: <5CDEA72D020000780023015E@prv1-mh.provo.novell.com> (raw)
While I've also already coded up the patch to actually support
the new BFloat16 insns, there's little point in submitting this
without having tested it. But the two preparatory patches may
turn out useful earlier on. They're based on the full AVX512
emulator series, but shouldn't be overly difficult to re-base
ahead of it.
1: x86/CPUID: support leaf 7 subleaf 1 / AVX512_BF16
2: x86emul: support CPUID subleaves for vcpu_has_*()
