From 1180509f6b3ec3ac2505375a78ccd72d270f2169 Mon Sep 17 00:00:00 2001 From: Zhao Yakui Date: Mon, 28 Jan 2008 13:53:42 +0800 Subject: ACPI : Update T-state coordination after getting _TSD info Accordint to ACPI spec, the _TSD object provides T-state control cross logical processor dependency information to OSPM. After the _TSD data for all cpus are obtained, OSPM will set up the T-state coordination between CPUs. Of course if the _TSD doesn't exist or _TSD data is incorrect , it is assumed that there is no T-state coordination and T-state is changed independently. Now there is no proper solution to update T-state coordination after one cpu is hotplugged. So this patch won't support hotplugged cpu very well.
