This patch series completes the removal of rte_smp_XX barrier functions that was announced over five years ago (20.05).
Most of this is mechanical with AI assistance, so strongly encourage maintainers to take a good look. Stephen Hemminger (32): bpf: replace deprecated SMP barriers with C11 fences test: remove test for rte_smp_mb bus/vmbus: fix ring buffer ordering on weakly ordered CPUs bus/vmbus: fix missing acquire on receive ring index bus/vmbus: replace SMP barriers with C11 memory fences baseband: convert rte_smp_rmb to fence net/hinic: replace rte_smp_rmb net/intel: replace rte_smp_rmb crypto_caam_jr: replace rte_smp_rmb net/virtio: replcae rte_smp_rmb net/thunderx: replace rte_smp_rmb stack: always use C11 memory model implementation ring: replace SMP read barrier with C11 acquire fence crypto/virtio: update comment reference to rte_smp_rmb event/sw: fix unlinks in progress counter races event/sw: replace SMP barriers with C11 atomics eal/x86: move optimized fence out of SMP barrier common/octeontx: remove redundant barrier in mbox crypto/caam_jr: use IO barrier before job ring doorbell crypto/octeontx: use IO barrier before doorbell mempool/octeontx: use IO barrier in pool destroy event/octeontx: replace deprecated SMP barriers event/dpaa2: replace deprecated barrier in selftest event/dsw: replace SMP barriers with release fences event/opdl: replace SMP barriers with C11 atomics net/netvsc: replace SMP barrier in RNDIS response net/thunderx: replace deprecated SMP barriers net/virtio: replace deprecated barrier in avail index update eal: remove stale SMP barrier in rte_service eal: remove rte_smp_XX checkpatches: no longer warn about rte_smp_XX doc: update release notes about rte_smp_XX removal app/test/meson.build | 1 - app/test/test_barrier.c | 288 ------------------ devtools/checkpatches.sh | 8 - doc/guides/rel_notes/deprecation.rst | 7 - doc/guides/rel_notes/release_26_11.rst | 6 + .../fpga_5gnr_fec/rte_fpga_5gnr_fec.c | 8 +- drivers/baseband/fpga_lte_fec/fpga_lte_fec.c | 12 +- drivers/bus/vmbus/private.h | 12 +- drivers/bus/vmbus/vmbus_bufring.c | 17 +- drivers/bus/vmbus/vmbus_channel.c | 10 +- drivers/common/octeontx/octeontx_mbox.c | 6 +- drivers/crypto/caam_jr/caam_jr.c | 5 +- .../crypto/octeontx/otx_cryptodev_hw_access.h | 4 +- drivers/crypto/virtio/virtqueue.h | 2 +- drivers/event/dpaa2/dpaa2_eventdev_selftest.c | 4 +- drivers/event/dsw/dsw_event.c | 8 +- drivers/event/octeontx/ssovf_evdev_selftest.c | 6 +- drivers/event/octeontx/ssovf_worker.c | 8 +- drivers/event/opdl/opdl_evdev.c | 7 +- drivers/event/sw/sw_evdev.c | 37 ++- drivers/event/sw/sw_evdev.h | 2 +- drivers/event/sw/sw_evdev_scheduler.c | 13 +- drivers/mempool/octeontx/octeontx_fpavf.c | 4 +- drivers/net/hinic/base/hinic_pmd_cmdq.c | 2 +- drivers/net/hinic/base/hinic_pmd_mgmt.c | 2 +- drivers/net/intel/ice/ice_rxtx.c | 2 +- drivers/net/intel/ixgbe/ixgbe_rxtx.c | 2 +- drivers/net/netvsc/hn_rndis.c | 2 +- drivers/net/thunderx/base/nicvf_hw.c | 3 +- drivers/net/thunderx/base/nicvf_plat.h | 5 +- drivers/net/virtio/virtqueue.h | 18 +- lib/bpf/bpf_pkt.c | 18 +- lib/eal/arm/include/rte_atomic_32.h | 6 - lib/eal/arm/include/rte_atomic_64.h | 6 - lib/eal/common/rte_service.c | 1 - lib/eal/include/generic/rte_atomic.h | 61 ---- lib/eal/loongarch/include/rte_atomic.h | 6 - lib/eal/ppc/include/rte_atomic.h | 6 - lib/eal/riscv/include/rte_atomic.h | 6 - lib/eal/x86/include/rte_atomic.h | 41 +-- lib/ring/rte_ring_gcc_pvt.h | 6 +- lib/stack/meson.build | 1 - lib/stack/rte_stack_lf.h | 4 - lib/stack/rte_stack_lf_generic.h | 153 ---------- 44 files changed, 156 insertions(+), 670 deletions(-) delete mode 100644 app/test/test_barrier.c delete mode 100644 lib/stack/rte_stack_lf_generic.h -- 2.53.0
