It also re-enables existing base test to help catch reported issues on some architectures. v9: - properly rebase patch integrating pmu and trace v8: - export __rte_pmu_trace_read from library itself to avoid build issues with msvc linker v7: - change test return value v6: - add more logs to functional test - skip test in case of setup failure, user must make sure system is properly configured to get valid results v5: - add missing patch that quiesces chincs check v4: - change fast test so that it won't fail on misconfigured system - fix compilation on windows v3: - do not export __rte_pmu_trace_read because that breaks compilation on windows - script generating map files does not handle conditional compilation - skip testing if paranoia is at wrong level v2: - explicitly check against NULL - make pmu lib optional by checking if dpdk config has RTE_LIB_PMU Tomasz Duszynski (8): lib/pmu: quiesce rte_pmu_read deprecation warning in chkincs lib/pmu: export only necessary arch headers lib/pmu: reimplement per-arch ops as callbacks lib/pmu: do not try enabling perf counter access on arm64 lib/pmu: use build system defined RTE_LIB_PMU macro test/pmu: enable test trace: add PMU lib/pmu: fix out-of-bound access MAINTAINERS | 1 + app/test/test_pmu.c | 60 ++++++++++++-- app/test/test_trace_perf.c | 10 +++ doc/guides/prog_guide/profile_app.rst | 5 ++ doc/guides/prog_guide/trace_lib.rst | 31 ++++++++ lib/eal/common/eal_common_trace.c | 5 +- lib/eal/common/eal_common_trace_pmu.c | 38 +++++++++ lib/eal/common/eal_common_trace_points.c | 5 ++ lib/eal/common/eal_trace.h | 4 + lib/eal/common/meson.build | 1 + lib/eal/include/rte_eal_trace.h | 16 ++++ lib/eal/include/rte_trace_point.h | 7 ++ lib/eal/include/rte_trace_point_register.h | 2 + lib/eal/meson.build | 3 + lib/meson.build | 2 +- lib/pmu/meson.build | 10 +-- lib/pmu/pmu.c | 92 ++++++++++++++++------ lib/pmu/pmu_arm64.c | 59 +++++--------- lib/pmu/pmu_private.h | 51 ++++++++++-- lib/pmu/rte_pmu.h | 49 +++++++++++- 20 files changed, 368 insertions(+), 83 deletions(-) create mode 100644 lib/eal/common/eal_common_trace_pmu.c -- 2.34.1
