From a73e818148ff2aa784a6691ec2d021ed07787e48 Mon Sep 17 00:00:00 2001 From: Thiago Macieira Date: Thu, 30 Aug 2018 15:59:41 +0000 Subject: x86: Move AESNI generation to Skylake and Goldmont MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The instruction set first appeared with Westmere, but not all processors in that and the next few generations have the instructions. According to Wikipedia[1], the first generation in which all SKUs have AES instructions are Skylake and Goldmont. I can't find any Skylake, Kabylake, Kabylake-R or Cannon Lake currently listed at https://ark.intel.com that says "Intel® AES New Instructions" "No".
