From d3d0f07fd58b4037a2f4a13f3fcbe7947ef1ad5d Mon Sep 17 00:00:00 2001 From: Matt DeVillier Date: Sat, 10 Nov 2018 17:44:36 -0600 Subject: soc/intel/braswell: add vmx support via CPU_INTEL_COMMON Braswell allready supported vmx, but offered no mechanism to unset it, nor to set the lock bit required for Windows to recognize virtualization. Enable this functionality by adding CPU_INTEL_COMMON config. Test: build/boot Windows 10 on Braswell ChromeOS device, verify Windows shows virtualization as enabled.
