From 00f1a29b2d62b729b6f428bfc662e6376d50fd73 Mon Sep 17 00:00:00 2001 From: Yihao Wu Date: Wed, 26 Feb 2020 21:56:35 +0800 Subject: [PATCH] configs: enable intel idle driver When c-state and mwait is passthroughed to the guest, enabling intel idle driver can exploit them and benefit the performance greatly. And potentially it can boost other features like haltpolling. The user should remove idle=* from kernel cmdline to put it to work.
