In accordance with\ntechnical board discussion February 2023.\nhttp://mails.dpdk.org/archives/dev/2023-February/263516.html\n\nThis initial series makes no attempt to adapt every use of builtin atomics\nfrom GCC it intends only to adapt the public API of the EAL presented as\na compatibility surface to applications.\n\nFurther series will be submitted to adapt the rest of DPDK to use standard\natomics that are 'internal' and not exposing or depending on the EAL API.\n\nThe choice has been made to break these two changes apart to allow more\nprecise analysis of any potential performance impact this change or\nsubsequent changes may introduce.\n\nAdditionally, it is not possible to break the commits up per driver/lib as\nboth the provider and consumer of the APIs need to be changed in the same\ncommit to maintain non-broken build and function.\n\nFinally, the first patch in this series is a duplication of Bruce Richardson\nseries https://patchwork.dpdk.org/project/dpdk/list/?series=29048 and is\nonly being provided to enable the CI run on this series. It is expected that\nBruce's series when committed will allow the build: require minimum c11 compiler\nhere to be dropped from this series.\n\nTyler Retzlaff (4):\n build: require minimum c11 compiler\n devtools: forbid use of GCC atomic builtins\n eal: adapt rte pause APIs to use C11 atomics\n eal: adapt rte spinlock and rwlock APIs to use C11 atomics\n\n app/test-bbdev/test_bbdev_perf.c | 123 ++++++++++++++++++++-----------\n app/test/test_func_reentrancy.c | 8 +-\n app/test/test_mcslock.c | 12 +--\n app/test/test_mempool_perf.c | 8 +-\n app/test/test_pflock.c | 12 +--\n app/test/test_pmd_perf.c | 10 +--\n app/test/test_ring_perf.c | 8 +-\n app/test/test_rwlock.c | 8 +-\n app/test/test_spinlock.c | 8 +-\n app/test/test_stack_perf.c | 12 +--\n app/test/test_ticketlock.c | 8 +-\n app/test/test_timer.c | 16 ++--\n devtools/checkpatches.sh | 8 ++\n drivers/event/opdl/opdl_ring.c | 47 ++++++------\n drivers/net/failsafe/meson.build | 1 -\n drivers/net/thunderx/nicvf_rxtx.c | 5 +-\n drivers/net/thunderx/nicvf_struct.h | 2 +-\n lib/bpf/bpf_pkt.c | 4 +-\n lib/distributor/distributor_private.h | 2 +-\n lib/distributor/rte_distributor_single.c | 44 +++++------\n lib/eal/arm/include/rte_pause_64.h | 28 +++----\n lib/eal/common/eal_common_errno.c | 1 +\n lib/eal/common/eal_memcfg.h | 2 +-\n lib/eal/include/generic/rte_pause.h | 52 ++++++-------\n lib/eal/include/generic/rte_rwlock.h | 46 ++++++------\n lib/eal/include/generic/rte_spinlock.h | 21 +++---\n lib/eal/include/rte_mcslock.h | 12 +--\n lib/eal/include/rte_pflock.h | 22 +++---\n lib/eal/include/rte_ticketlock.h | 8 +-\n lib/eal/loongarch/include/rte_pause.h | 2 -\n lib/eal/ppc/include/rte_pause.h | 2 -\n lib/eal/riscv/include/rte_pause.h | 2 -\n lib/eal/x86/include/rte_spinlock.h | 2 +-\n lib/ring/rte_ring_core.h | 5 +-\n lib/ring/rte_ring_generic_pvt.h | 19 +++--\n lib/ring/rte_ring_peek_elem_pvt.h | 2 +-\n meson.build | 1 +\n 37 files changed, 311 insertions(+), 262 deletions(-)" }
