In the techboard of April 22, it has been decided to block patches using rte_atomicNN_xx and rte_smp_*mb APIs, starting DPDK 20.08. Meeting minutes: http://mails.dpdk.org/archives/dev/2020-April/165143.html Deprecation notice: http://doc.dpdk.org/guides/rel_notes/deprecation.html
Some doc has been submitted to help understanding how to manage atomics: http://doc .dpdk.org/guides/prog_guide/writing_efficient_code.html#locks-and-atomic-operations Unfortunately the tool to check new code was merged last week: http://git.dpdk.org/dpdk/commit/?id=f1602b4a86 As a consequence, I propose to apply the "reject rule" starting DPDK 20.11. Can we make this rule better advertised with an announce message? Are the current technical explanations enough? If not, it would be wonderful to have a blog post explaining the details, as part of an announce.
