Preceded by a new user event PERF_RECORD_ITRACE. The buffer is an AUX areaīuffer although the details of the AUX area are not implementedīecause the kernel support is pending. Recording consists of mmapping a separate buffer and copying The abstraction has two separate aspects: Perf tools: Only override the default :tid comm entry That introduce an abstraction for Instruction tracing.
