From 0601f1e164a95342a7c381603284c11a9a588804 Mon Sep 17 00:00:00 2001 From: Youness Alaoui Date: Fri, 9 Feb 2018 18:44:45 -0500 Subject: purism/librem_skl: Enable VMX and Intel SpeedStep in devicetree Although VmxEnable is currently ignored by FSP, a forthcoming patch explicitly enables it in coreboot, so set it in anticipation of that. Enable Intel SpeedStep to ensure the ACPI tables are generated for the C-states/P-states which are required for the xen-acpi-processor module to be loaded. Without it, the Qubes 4.0-rc4 installer will complain at boot about modules that could not be loaded.
