Subject: [PATCH 0/3] sched: asymmetrical packing for POWER7 SMT4
Date: Tue, 08 Jun 2010 14:57:02 +1000 [thread overview]
Message-ID: <1275973022.91203.586435002889.qpush@pale> (raw)
This patch series implements asymmetric SMT packing which ensures
consistently good performance on POWER7. Without this series, tasks
will vary in performance by around +/-30% on POWER7
This new version is based on help from Vatsa and Vaidy in an attempt
to answer concerns that Peter Zijlstra had about the original series.
The 1st patch is a fix for SMT4 in general.
The 2nd adds actual the asymmetrical packing infrastructure.
The 3rd adds the powerpc specific hooks for POWER7.
