From 424b0c7103b71c50396219352cc5f13a9078a461 Mon Sep 17 00:00:00 2001 From: Leah Rowe Date: Sun, 29 Dec 2024 02:10:03 +0000 Subject: t480/3050micro: disable hyperthreading Hyperthreading is a risk factor for spectre/meltdown and other attacks. Disabling it is a best practise. Those who need it can always turn this option back on. Otherwise, disabling it by default is a simply courtesy to the average user, in the interest of security.
