Hello, This series addresses a number of issues and limitations I have identified over time in the trace subsystem.
The main issue was with dynamically enabling trace points which was not working if no trace point had been enabled at rte_eal_init() time. This is 22.11 material. We may start thinking about marking this API stable, but this is another topic. -- David Marchand Changes since v3: - added one more change for creating new trace directory on call to rte_trace_save(), - added the telemetry commands patch in the series, Changes since v2: - fixed trace point name storage, Changes since v1: - split patch 3, - addressed comments on (previously) patch 4, David Marchand (11): trace: fix mode for new trace point trace: fix mode change trace: fix leak with regexp trace: rework loop on trace points trace: fix dynamically enabling trace points trace: fix race in debug dump trace: fix metadata dump trace: remove limitation on trace point name trace: remove limitation on directory trace: create new directory for each trace dump trace: enable trace operations via telemetry app/test/test_trace.c | 67 +++---- app/test/test_trace.h | 2 + doc/guides/prog_guide/trace_lib.rst | 53 +++++- lib/eal/common/eal_common_trace.c | 192 ++++++++++++++------- lib/eal/common/eal_common_trace_ctf.c | 3 - lib/eal/common/eal_common_trace_utils.c | 132 ++++++-------- lib/eal/common/eal_trace.h | 13 +- lib/eal/include/rte_trace_point_register.h | 3 +- lib/telemetry/telemetry_data.c | 1 + 9 files changed, 279 insertions(+), 187 deletions(-) -- 2.37.3
