Nested message and enum types in FtraceConfig.

Modules§

Structs§

  • CompactSchedConfig
    Configuration for compact encoding of scheduler events. When enabled (and recording the relevant ftrace events), specific high-volume events are encoded in a denser format than normal.
  • PrintFilter
    Optional filter for “ftrace/print” events.

Enums§

  • KsymsMemPolicy
    When symbolize_ksyms=true, determines whether the traced_probes daemon should keep the symbol map in memory (and reuse it for future tracing sessions) or clear it (saving memory) and re-create it on each tracing session (wasting cpu and wall time). The tradeoff is roughly: KSYMS_RETAIN: pay a fixed ~1.2 MB cost after the first trace. KSYMS_CLEANUP_ON_STOP: pay a ~300-500ms cost when starting each trace. Default behavior: KSYMS_CLEANUP_ON_STOP.
