hi,
this patchset is adding the support to reused metric in
another metric.
For example, to define IPC by using CPI with change like:
{
"BriefDescription": "Instructions Per Cycle (per Logical Processor)",
- "MetricExpr": "INST_RETIRED.ANY / CPU_CLK_UNHALTED.THREAD",
+ "MetricExpr": "1/CPI",
"MetricGroup": "TopDownL1",
"MetricName": "IPC"
},
I won't be able to find all the possible places we could
use this at, so I wonder you guys (who was asking for this)
would try it and come up with comments if there's something
missing or we could already use it at some places.
It's based on Arnaldo's tmp.perf/core.
v4 changes:
- removed acks from patch because it changed a bit
with the last fixes:
perf metric: Collect referenced metrics in struct metric_ref_node
- fixed runtime metrics [Kajol Jain]
- increased recursion depth [Paul A. Clarke]
- changed patches due to dependencies:
perf metric: Collect referenced metrics in struct metric_ref_node
perf metric: Add recursion check when processing nested metrics
perf metric: Rename struct egroup to metric
perf metric: Rename group_list to metric_list
