Hi Jan,
Any chance you can get the contents of /sys/kernel/mm/hugepages
before and after the first run of libhugetlbfs testsuite on Power?
Perhaps a script like:
cd /sys/kernel/mm/hugepages
for f in hugepages-*/*; do
n=`cat $f`;
echo -e "$n\t$f";
done
Just want to make sure the numbers look as they should.
