Motivation ========== DPDK pdump capture tool currently runs as secondary on the default core 0. For all --pdump, core 0 iterates and capture packets. This leads to drops and delay in the capture. This introduces skew in result and performance bottleneck. In order to allow --pdump to unique cores, the pdump application has to be support multi-core in EAL arguments and each --pdump has to be mapped to unique cores. Status ====== - Default c_flag option is removed. - with option --multi, the application can run on unique cores. Change Log: =========== V4: - spelling correction - Reshma Pathan - remove c_falg - Reshma Pathan V3: - correct the parse_usage - Vipin Varghese - add change log - Vipin Varghese V2: - Replace option '-c' to '-l' - Keith Wiles Vipin Varghese (2): app/pdump: remove core restriction app/pdump: enhance to support multi-core capture app/pdump/main.c | 90 ++++++++++++++++++++++++++++++-------- doc/guides/tools/pdump.rst | 8 +++- 2 files changed, 78 insertions(+), 20 deletions(-) Future: ======= - In --multi mode, allow master to stop --pdump for desired packets. - In --multi mode, allow master to stop --pdump for desired file size. -- 2.17.1
