Subject: /proc/pid/numa_maps no longer shows "default" policy
Date: Thu, 30 Jan 2014 17:34:57 +1100 [thread overview]
Message-ID: <20140130173457.115a30f8@kryten> (raw)
Hi Mel,
We recently noticed that /proc/pid/numa_maps used to show default
policy mappings as such:
cat /proc/self/numa_maps
00100000 default mapped=1 mapmax=339 active=0 N0=1
But now it shows them as prefer:X:
cat /proc/self/numa_maps
10000000 prefer:1 file=/usr/bin/cat mapped=1 N0=1
It looks like this was caused by 5606e387 (mm: numa: Migrate on
reference policy). I'm not sure if this is expected, but we don't have
CONFIG_NUMA_BALANCING enabled on ppc64 so I wasn't expecting processes
to have a particular node affinity by default.
Anton
