Subject: [PATCH 0/4] Advertise CPUID for new instructions in Clearwater Forest
Date: Mon,  4 Nov 2024 14:35:55 +0800	[thread overview]
Message-ID: <20241104063559.727228-1-tao1.su@linux.intel.com> (raw)

Latest Intel platform Clearwater Forest has introduced new instructions
for SHA512, SM3, SM4 and AVX-VNNI-INT16.

This patch set is for advertising these CPUIDs to userspace so that guests
can query them directly. Since these new instructions can't be intercepted
and only use xmm, ymm registers, host doesn't require to do additional
enabling for guest.

These new instructions are already updated into SDM [1].
