Bug ID: 3879
Summary: example/l2fwd_simple fails on some systems when using
1GB huge pages
Product: OpenDataPlane - linux- generic reference
Version: v1.15.0.0
Hardware: Other
OS: Linux
Status: UNCONFIRMED
Severity: enhancement
Priority: ---
Component: General ODP
Assignee: maxim.uva...@linaro.org
Reporter: josep.puigdem...@linaro.org
CC: lng-odp@lists.linaro.org
Target Milestone: ---
one of the processes of l2fwd_example gets stuck in futex_wait_queue_me while
at the same time consuming CPU. The other process meanwhile waits in
__skb_wait_for_more_packets in the kernel.
This happens when using 1G huge pages on a Intel Xeon E5-2620v3 (linux kernel
4.13.0-19), and it is not observed when using 2M huge pages on the same system
and kernel.
On an i7-7500U using 1GB huge pages, and linux 4.16.12, this is not observed.
