Subject: [PATCH 4/8] x86, topology: Swap semantic of core_siblings and cpu_node_siblings
Date: Fri, 7 Aug 2009 14:59:18 +0200 [thread overview]
Message-ID: <20090807125918.GW6520@alberich.amd.com> (raw)
In-Reply-To: <20090807125609.GH7198@alberich.amd.com>
Brice Goglin suggested to use the following semantic for
CPU topology information
Level | Set of CPUs
--------------|---------------
phys_package | cpu_node_siblings
cpu_node | core_siblings
core | thread_siblings
thread | one CPU
Done that.
