Subject: [PATCH v0 36/71] perf tools: Add support for parsing pmu itrace_config
From: Adrian Hunter <adrian.hunter@...el.com>
Instruction Tracing uses a new perf_event_attr member
named itrace_config. Add support for parsing pmu format
values and term types based on itrace_config.
Signed-off-by: Adrian Hunter <adrian.hunter@...el.com>
