+ZXDH Poll Mode Driver
+======================
+
+The ZXDH PMD (**librte_net_zxdh**) provides poll mode driver support
+for 25/100 Gbps ZXDH NX Series Ethernet Controller based on
+the ZTE Ethernet Controller E310/E312.
+
+
+Features
+--------
+
+Features of the zxdh PMD are:
+
+- Multi arch support: x86_64, ARMv8.
+
+Prerequisites
+-------------
+
+- Learning about ZXDH NX Series Ethernet Controller NICs using
+ `<https://enterprise.zte.com.cn/sup-detail.html?id=271&suptype=1>`_.
+
+Driver compilation and testing
+------------------------------
+
+Refer to the document :ref:`compiling and testing a PMD for a NIC <pmd_build_and_test>`
+for details.
+
+Limitations or Known issues
+---------------------------
+X86-32, Power8, ARMv7 and BSD are not supported yet.

We haven't found the detailed reason for the error in the output log. I noticed that the patches submitted by others also have this error. It was a false positive when testing your series (on top of next-net repo at the time) and you can ignore this failure. This is fixed in the main repo with: 899cffe059b8 ("test/bitops: fix 32-bit atomic test spurious failure"). next-net was rebased recently and contains the fix. -- David Marchand ^ permalink raw reply [flat|nested] 207+ messages in thread

V5: - split driver into multiple patches,part of the zxdh driver, later provide dev start/stop,queue_setup,npsdk_init,mac,vlan,rss ,etc. - fix errors reported by scripts. - move the product link in zxdh.rst. - fix meson check use RTE_ARCH_X86_64/RTE_ARCH_ARM64. - modify other comments according to Ferruh's comments.

Unlike some other OS's. DPDK best practice is to only use packed where required by the hardware. Please don't use __rte_packed unless needed. To save space, it makes sense to reorder structure members to fill holes and put hot members together for caching. You should put fake_mbuf at the end and mark it with __rte_cache_aligned. ^ permalink raw reply [flat|nested] 207+ messages in thread

But '/**<' is doxygen sytax to say comment is for the code before it, not after. So it is used wrong above. If you don't have any specific reason, why not using regular comments (non doxygen syntax), and leave first line empty, and terminate with '*/', so above becomes: /* * physical address of vring, or virtual address */ This comment is for all comment code in all the series.

Hi Ferruh, The complete driver function has been implemented. At present, the driver function is integrated in batches. The integrated PMD does not cause the crash but cannot support all PMD functions.We plan to integrate the driver in this version and finally provide a complete and available driver. In the current phase, we will marking driver as experimental in the maintainers file and document the restrictions in the driver documentation, also clarify this in the release notes update. Thanks.

Sounds good, thanks. Btw, build should be fine after each patch, but in this patch series there are warnings in some early patches, can you please fix them in next version? @Aaron, @David, what do you think to add patch by patch build to the CI?

I would love to have patch by patch tests too, but I don't think UNH can handle such load. We could limit at doing this patch by patch in GHA / ovsrobot only (which I think it is done for OVS CI). -- David Marchand ^ permalink raw reply [flat|nested] 207+ messages in thread

This finds bugs but can generate false positives. The output is quite verbose. It complains about this which may or may not be a real problem. If memcpy() is used instead of rte_memcpy() then the problem goes away. The issue is that inlined version rte_memcpy() will reference past the arguments as an internal optimization for small values.
