Hi Min Zhou, It looks like Loongson Lab has had some timeouts for docs patches this week: https://mails.dpdk.org/archives/test-report/2025-July/894285.html https://mails.dpdk.org/archives/test-report/2025-July/894666.html You might have to use the -t argument to extend your meson test timeout if it is currently too short for some of the unit tests.
