Subject: [patch 0/4] C2 "emulation"
Date: Sat, 24 May 2008 20:43:42 -0300 [thread overview]
Message-ID: <20080524234342.983197667@localhost.localdomain> (raw)
As discussed before the TSC is unreliable as a clocksource for KVM
guests, especially with CPU migration.
The following patchset changes the QEMU ACPI tables to report a valid C2
state temporarily to force guests to switch to more reliable ones.
Also allow direct access to the PMTimer port which is constantly used
in C1 idle.
Tested with Linux and Windows XP.
