Hi,
Since release 1.7.1 and patchset "tailq fully local", the test
eal_flags_autotest doesn't work anymore. It fails because it doesn't
find any free hugepage (rte_memzone_reserve).
The interesting commits are:
http://dpdk.org/browse/dpdk/commit/?id=e3f3b68c6e42
http://dpdk.org/browse/dpdk/commit/?id=dd0024ccbc70
The test works only when these patches are reverted.
Here is how to reproduce:
git revert e3f3b68c6e42
git revert dd0024ccbc70
make config T=x86_64-native-linuxapp-gcc
make
mkdir -p /mnt/huge
mount -t hugetlbfs nodev /mnt/huge
echo 9 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages
build/app/test -c 1 -n 1 -m 1
eal_flags_autotest
I'd like this regression to be fixed for the coming release.
If someone has an idea, he's welcome :)
Thanks
