From 5d55ddd882498945ac7d33343503a33642e198d9 Mon Sep 17 00:00:00 2001 From: Konrad Rzeszutek Wilk Date: Fri, 23 Mar 2012 09:45:56 -0400 Subject: linux-xencommons: Load xen-acpi-processor Upstream the "xen/acpi-processor: C and P-state driver that uploads said data to hypervisor." takes care of uploading power information information that normally a cpu frequency scaling driver would using in the initial domain. We want the hypervisor to take that data and make good usage of it. Fortunatly for us we do not have to worry about the native cpu frequency scaling drivers being loaded first, as the upstream commit: "xen/cpufreq: Disable the cpu frequency scaling drivers from loading." takes care of that. Meaning we can load the xen-acpi-processor at any time. By default that driver is built as a module - and since we are the only user of it - we should load it.
