From 7943e5513cbe7a0d910c0fba025c7eb70d0fe71e Mon Sep 17 00:00:00 2001 From: Christian Breunig Date: Tue, 5 Mar 2024 20:32:16 +0100 Subject: T2447: add configurable kernel boot option 'disable-power-saving' Lower available CPU C states to a minimum if this option set. This will set Kernel commandline options "intel_idle.max_cstate=0 processor.max_cstate=1".
