* Define timerlat tracing mode.
*
* There are three tracing modes:
* - tracefs-only, used when BPF is unavailable.
* - BPF-only, used when BPF is available and neither trace saving nor
* auto-analysis are enabled.
* - mixed mode, used when BPF is available and either trace saving or
* auto-analysis is enabled (which rely on sample collection through
* tracefs).
