The function rte_thread_create_control() does not take attributes anymore as it looks a useless complication of the API. Then the rte_thread API is made stable, so we can remove the old deprecated functions rte_thread_setname() and rte_ctrl_thread_create(). Some new internal functions are added in rte_thread to make sure all internal thread names are prefixed with "dpdk-". Few other cleanups are done. Future work about pthread portability are about: - cancel - mutex Thomas Monjalon (11): devtools: warn when adding some pthread calls eal: rename thread name length definition eal: remove attributes from control thread creation eal: promote thread API as stable eal: force prefix for internal threads lib: convert to internal control threads drivers: convert to internal control threads examples: convert to normal control threads test: convert threads creation eal: remove deprecated thread functions lib: remove pthread.h from includes app/test/process.h | 10 +- app/test/test_lcores.c | 9 +- app/test/test_link_bonding.c | 2 + app/test/test_pdump.c | 6 +- app/test/test_pdump.h | 2 +- app/test/test_threads.c | 2 +- devtools/checkpatches.sh | 16 +++ .../prog_guide/env_abstraction_layer.rst | 2 +- doc/guides/rel_notes/deprecation.rst | 5 - doc/guides/rel_notes/release_23_11.rst | 6 + drivers/common/cnxk/roc_dev.c | 16 +-- drivers/common/cnxk/roc_dev_priv.h | 2 +- drivers/common/cnxk/roc_nix_inl_dev.c | 9 +- drivers/common/cnxk/roc_nix_inl_priv.h | 2 +- drivers/common/cnxk/roc_platform.h | 3 +- drivers/common/mlx5/mlx5_common.c | 1 + drivers/common/mlx5/windows/mlx5_win_ext.h | 2 + drivers/dma/skeleton/skeleton_dmadev.c | 8 +- drivers/event/dlb2/pf/base/dlb2_osdep.h | 14 +- drivers/event/dlb2/pf/base/dlb2_resource.c | 39 +++--- drivers/event/dlb2/pf/dlb2_main.h | 1 - drivers/net/ark/ark_ethdev.c | 11 +- drivers/net/ark/ark_pktgen.c | 8 +- drivers/net/ark/ark_pktgen.h | 2 +- drivers/net/bnxt/bnxt.h | 1 + drivers/net/iavf/iavf_vchnl.c | 4 +- drivers/net/ice/ice_dcf_parent.c | 7 +- drivers/net/ipn3ke/ipn3ke_representor.c | 17 ++- drivers/net/ixgbe/ixgbe_ethdev.c | 8 +- drivers/net/mlx5/mlx5.h | 2 +- drivers/net/mlx5/mlx5_hws_cnt.c | 42 +++--- drivers/net/qede/base/bcm_osal.h | 1 + drivers/net/sfc/sfc_mae.h | 2 +- drivers/net/sfc/sfc_mae_counter.c | 11 +- drivers/net/txgbe/txgbe_ethdev.c | 6 +- drivers/raw/ifpga/base/opae_osdep.h | 1 + drivers/raw/ifpga/ifpga_rawdev.c | 19 ++- drivers/vdpa/ifc/ifcvf_vdpa.c | 86 ++++++------ drivers/vdpa/mlx5/mlx5_vdpa.c | 2 +- drivers/vdpa/mlx5/mlx5_vdpa.h | 10 +- drivers/vdpa/mlx5/mlx5_vdpa_cthread.c | 70 +++------- drivers/vdpa/mlx5/mlx5_vdpa_event.c | 64 +++------ drivers/vdpa/sfc/sfc_vdpa.c | 1 + drivers/vdpa/sfc/sfc_vdpa_ops.c | 15 +- drivers/vdpa/sfc/sfc_vdpa_ops.h | 3 +- examples/vhost/main.c | 9 +- examples/vhost_blk/vhost_blk.c | 21 +-- lib/eal/common/eal_common_options.c | 1 + lib/eal/common/eal_common_proc.c | 15 +- lib/eal/common/eal_common_thread.c | 101 +++++--------- lib/eal/common/eal_common_trace.c | 1 + lib/eal/common/malloc_mp.c | 1 + lib/eal/freebsd/eal.c | 2 +- lib/eal/freebsd/eal_alarm.c | 1 + lib/eal/freebsd/eal_interrupts.c | 10 +- lib/eal/freebsd/eal_thread.c | 9 +- lib/eal/include/rte_eal.h | 3 - lib/eal/include/rte_lcore.h | 42 ------ lib/eal/include/rte_per_lcore.h | 2 - lib/eal/include/rte_thread.h | 131 +++++++++--------- lib/eal/linux/eal.c | 2 +- lib/eal/linux/eal_alarm.c | 1 + lib/eal/linux/eal_interrupts.c | 10 +- lib/eal/linux/eal_thread.c | 18 +-- lib/eal/linux/eal_timer.c | 11 +- lib/eal/unix/rte_thread.c | 2 +- lib/eal/version.map | 44 +++--- lib/eal/windows/eal.c | 2 +- lib/eal/windows/eal_interrupts.c | 2 +- lib/eal/windows/eal_thread.c | 8 -- lib/eal/windows/rte_thread.c | 2 +- lib/ethdev/ethdev_driver.c | 1 + lib/ethdev/ethdev_driver.h | 2 + lib/ethdev/rte_ethdev_core.h | 2 - lib/ethdev/rte_flow.c | 1 + lib/eventdev/rte_event_eth_rx_adapter.c | 24 ++-- lib/vhost/fd_man.c | 6 +- lib/vhost/fd_man.h | 2 +- lib/vhost/socket.c | 23 ++- lib/vhost/vduse.c | 5 +- lib/vhost/vhost.c | 1 + 81 files changed, 451 insertions(+), 617 deletions(-)
