The patch series adds a how-to guide for debugging and troubleshooting tips. Motivation ========== DPDK proc-info tool is been enhanced to accommodate the debug information for the port, traffic manager crypto, ring and mempool contents. With these additional information, it becomes easy to analyze issues and performance variance. But applications are designed based on the target platform, workload, poll mode drivers, and multi-process. This raises variance in debugging and collecting data. Hence attempt of patch series is identified such symptoms and share step by step guide to cover the cases. Not all possible cases could be covered in a single attempt. But with feedback and support from the community, this can be expanded. Status ====== Reviews and changes accommodated. ACK received for documentation and SVG files. Change Log ========== V8: - remove quotes from notes section - John Macnamara - add quotes for DPDK API and variables - Thomas Monjalon - update use of JUMBO for rx bottleneck - Vipin Varghese - Add ACK from v7 - Vipin Varghese V7: - add space to note and indent - John Macnamara V6: - correction for word style and grammar - Thomas Monjalon - add license for svg files - Vipin Varghese v5: - rework of content - Vipin Varghese V4: - Correction for word style - Shreyansh Jain V3: - reorder for removing warning in 'make doc-guides-html' - Thomas Monjalon V2: - add offload flag check - Vipin Varghese - change tab to space - Marko Kovacevic - spelling correction - Marko Kovacevic - remove extra characters - Marko Kovacevic - add ACK by Marko - Vipn Varghese - add ACK from Marko - Vipin Varghese Vipin Varghese (2): doc: add svg for debug and troubleshoot guide doc: add guide for debug and troubleshoot doc/guides/howto/debug_troubleshoot_guide.rst | 464 ++++++++++++++++++ doc/guides/howto/img/dtg_consumer_ring.svg | 24 + doc/guides/howto/img/dtg_crypto.svg | 21 + .../howto/img/dtg_distributor_worker.svg | 36 ++ doc/guides/howto/img/dtg_mempool.svg | 27 + doc/guides/howto/img/dtg_pdump.svg | 33 ++ doc/guides/howto/img/dtg_producer_ring.svg | 24 + doc/guides/howto/img/dtg_qos_tx.svg | 29 ++ doc/guides/howto/img/dtg_rx_rate.svg | 25 + doc/guides/howto/img/dtg_rx_tx_drop.svg | 33 ++ doc/guides/howto/img/dtg_sample_app_model.svg | 110 +++++ doc/guides/howto/img/dtg_service.svg | 20 + doc/guides/howto/index.rst | 1 + 13 files changed, 847 insertions(+) create mode 100644 doc/guides/howto/debug_troubleshoot_guide.rst create mode 100644 doc/guides/howto/img/dtg_consumer_ring.svg create mode 100644 doc/guides/howto/img/dtg_crypto.svg create mode 100644 doc/guides/howto/img/dtg_distributor_worker.svg create mode 100644 doc/guides/howto/img/dtg_mempool.svg create mode 100644 doc/guides/howto/img/dtg_pdump.svg create mode 100644 doc/guides/howto/img/dtg_producer_ring.svg create mode 100644 doc/guides/howto/img/dtg_qos_tx.svg create mode 100644 doc/guides/howto/img/dtg_rx_rate.svg create mode 100644 doc/guides/howto/img/dtg_rx_tx_drop.svg create mode 100644 doc/guides/howto/img/dtg_sample_app_model.svg create mode 100644 doc/guides/howto/img/dtg_service.svg Future Work =========== - More use cases. - Runs as non root. - Effects of Cache partitioning. - How to run application as non root user.
