Hello,
I am currently working on a patch to fix the eal_flags_autotest test as
it currently fails on many platforms.
I have made some progress, however I stumbled upon a possible issue with
EAL and hugepages.
Looking at the code and some documentation it appears to me that
hupepages are supposed to be automatically deleted on dynamic memory
mode as the dpdk process exits.
The test however reports that this is not happening.
This can be shown by:
bash# export DPDK_TEST=eal_flags_autotest
bash# ./build/app/test/dpdk-test
...
Error - hugepage files for memtest1 were not deleted!
Error in test_file_prefix()
Test Failed
bash# ls /dev/hugepages/ #hugetlbfs is mounted on /dev/hugepages
memtest1map_0 memtest1map_1 memtest1map_2 memtest1map_3
memtest1map_4 memtest1map_5 memtest1map_6 memtest1map_7
memtest1map_8 rtemap_0
To me it appears that the hugepages are in fact not being deleted correctly.
Is this an anomaly or is anyone else seeing this issue as well?
