this series provides basic dependencies for additional eal thread api additions. series includes * basic platform error number conversion. * function to get current thread identifier. * functions to get and set affinity with platform agnostic thread identifier. * minimal unit test of get and set affinity demonstrating usage. note: previous series introducing these functions is now superseded by this series. http://patches.dpdk.org/project/dpdk/list/?series=20472&state=* Tyler Retzlaff (4): eal/windows: translate Windows errors to errno-style errors eal: add basic thread ID and current thread identifier API eal: implement functions for get/set thread affinity test/threads: add unit test for thread API v2: * add missing boilerplate comments warning of experimental api for rte_thread_{set,get}_affinity_by_id(). * don't break literal format string to log_early to improve searchability. * fix multi-line comment style to match file. * return ENOTSUP instead of EINVAL from rte_convert_cpuset_to_affinity() if cpus in set are not part of the same processor group and note limitation in commit message. * expand series to include rte_thread_self(). * modify unit test to remove use of implementation detail and get thread identifier use added rte_thread_self(). * move literal value to rhs when using memcmp in RTE_TEST_ASSERT app/test/meson.build | 2 + app/test/test_threads.c | 89 ++++++++++++++++++ lib/eal/include/rte_thread.h | 64 +++++++++++++ lib/eal/unix/rte_thread.c | 27 ++++++ lib/eal/version.map | 5 ++ lib/eal/windows/eal_lcore.c | 173 ++++++++++++++++++++++++++--------- lib/eal/windows/eal_windows.h | 10 +++ lib/eal/windows/include/rte_os.h | 2 + lib/eal/windows/rte_thread.c | 190 ++++++++++++++++++++++++++++++++++++++- 9 files changed, 517 insertions(+), 45 deletions(-) create mode 100644 app/test/test_threads.c
