Hi Chengwen,
The output from the API tests is not very straightforward to interpret if you
are not familiar with these tests.
Could we change the log level of the dmadev library before and after the API
tests using something similar to
The code I have included inline below?

/* Set dmadev log level to critical to suppress unnecessary output
during API tests. */
rte_log_set_level_pattern("lib.dmadev", RTE_LOG_CRIT);

rte_log_set_level_pattern("lib.dmadev", RTE_LOG_INFO);

This change would bring your output down from:
