Fix several test infrastructure issues affecting high core count systems. Add rte_pause() to synchronization spinloops that starve SMT sibling threads on AMD Zen systems. Scale iteration counts inversely with core count via a new test_scale_iterations() helper to prevent timeouts from lock contention (atomic, mcslock, stack, timer_secondary tests).
Replace volatile variables with C11 atomics in timer_secondary, fix parallel test execution by restoring unique file-prefix for fast-tests on Linux, and fix BPF ELF load test error handling and clang 20+ compatibility. v4 - drop patches already covered elsewhere - replace volatile with C11 atomics in timer secondary test - add missing mempool_get error check in timer secondary test - move iteration scaling out of worker function in stack test Stephen Hemminger (11): test: add pause to synchronization spinloops test/atomic: scale test based on core count test/mcslock: scale test based on number of cores test/stack: scale test based on number of cores test/timer: scale test based on number of cores test/timer: replace volatile with C11 atomics test: add file-prefix for all fast-tests on Linux test: fix trace_autotest_with_traces parallel execution test/bpf: fix error handling in ELF load tests test/bpf: fix unsupported BPF instructions in ELF load test test/bpf: pass correct size for Rx/Tx load tests app/test/bpf/meson.build | 3 +- app/test/suites/meson.build | 19 +++++++--- app/test/test.h | 19 ++++++++++ app/test/test_atomic.c | 66 +++++++++++++++++++-------------- app/test/test_bpf.c | 7 ++-- app/test/test_mcslock.c | 10 +++-- app/test/test_stack.c | 11 ++++-- app/test/test_threads.c | 17 +++++---- app/test/test_timer_secondary.c | 45 ++++++++++++++-------- 9 files changed, 131 insertions(+), 66 deletions(-) -- 2.51.0
