Hi, I think I find the problem.
In builtin-script.c, array output_fields should also be
changed,PERF_OUTPUT_ADDR should added to [PERF_TYPE_SOFTWARE], am I
right?
static u64 output_fields[PERF_TYPE_MAX] = {
....
[PERF_TYPE_SOFTWARE] = PERF_OUTPUT_COMM | PERF_OUTPUT_TID | \
PERF_OUTPUT_CPU | PERF_OUTPUT_TIME | \
PERF_OUTPUT_EVNAME | PERF_OUTPUT_SYM | \
PERF_OUTPUT_ADDR,
Here is the output:
