The operation '%' is not implemented on event-parse.c, causing an error
when parsing events with '%' the operation in its printk format. For
example,
# perf record -e sched:sched_deadline_yield ~/yield-test
Warning: [sched:sched_deadline_yield] unknown op '%'
....
# perf script
Warning: [sched:sched_deadline_yield] unknown op '%'
test 1641 [006] 3364.109319: sched:sched_deadline_yield: \
[FAILED TO PARSE] now=3364109314595 \
deadline=3364139295135 runtime=19975597
This patch implements the '%' operation. With this patch, we see the
correct output:
# perf record -e sched:sched_deadline_yield ~/yield-test
No Warning
# perf script
yield-test 4005 [001] 4623.650978: sched:sched_deadline_yield: \
now=4623.650974050 \
deadline=4623.680957364 remaining_runtime=19979611
