Subject: [PATCH v3 02/27] eal: reimplement rte_smp_*mb with rte_atomic_thread_fence
Date: Sat, 23 May 2026 12:16:04 -0700 [thread overview]
Message-ID: <20260523195604.441947-3-stephen@networkplumber.org> (raw)
In-Reply-To: <20260523195604.441947-1-stephen@networkplumber.org>
The rte_smp_mb(), rte_smp_wmb() and rte_smp_rmb() functions were
flagged as deprecated by commit 3ec965b6de12 ("doc: update atomic
operation deprecation") in 2021 but nothing came of it.
Reimplement them as inline wrappers over rte_atomic_thread_fence()
and drop the deprecation notice.
The API is preserved; only the implementation changes.
Generated code is unchanged on x86 (seq_cst keeps the lock-addl
trick, release/acquire collapse to a compiler barrier under TSO).
On arm64, release/acquire emit dmb ish instead of dmb ishst/ishld;
the difference is below measurement noise.
Drop restriction frm checkpatch since they are no longer
really on deprecation cycle.

-* rte_smp_*mb: These APIs provide full barrier functionality. However, many
- use cases do not require full barriers. To support such use cases, DPDK has
- adopted atomic operations from
- https://gcc.gnu.org/onlinedocs/gcc/_005f_005fatomic-Builtins.html. These

* lib: will fix extending some enum/define breaking the ABI. There are multiple
samples in DPDK that enum/define terminated with a ``.*MAX.*`` value which is
used by iterators, and arrays holding these values are sized with this
