In accordance with > technical board discussion February 2023. > http://mails.dpdk.org/archives/dev/2023-February/263516.html > > This initial series makes no attempt to adapt every use of builtin atomics > from GCC it intends only to adapt the public API of the EAL presented as > a compatibility surface to applications. > > Further series will be submitted to adapt the rest of DPDK to use standard > atomics that are 'internal' and not do not straddle the EAL API. > > The choice has been made to break these two changes apart to allow more > precise analysis of any potential performance impact this change or > subsequent changes may introduce. > > Additionally, it is not possible to break the commits up per driver/lib as > both the provider and consumer of the APIs need to be changed in the same > commit to maintain non-broken build and function. > > Finally, the first patch in this series is a duplication of Bruce Richardson > series https://patchwork.dpdk.org/project/dpdk/list/?series=29048 and is > only being provided to enable the CI run on this series. It is expected that > Bruce's series when committed will allow the build: require minimum c11 > compiler > here to be dropped from this series. > > v2: > * remove volatile qualification from variables, structure fields and > parameters that have been qualified _Atomic > * restore removal of #include <rte_atomic.h> in rte_ring_core.h the ring > library still uses other rte_atomic APIs and types that are not replaced > by the standard or compiler intrinsics > * add missing adaption to stdatomic in ring/rte_ring_c11_pvt.h
