I would like to access the HPC counters using the simpleperf command for all the processes running in the system parallely.
For linux OS , this script works
#!/bin/sh
#set -x
ps -ef | awk ‘{printf($2)"\n";}’ > out.txt
sed ‘1d’ out.txt > tmp
IFS=$’\n’
while read tmp
do
3>results-$tmp perf stat -p $tmp --log-fd 3 sleep 5 > /dev/null &
done <tmp
But since the Hikey960 has Android OS, I have replaced the line
3>results-$tmp perf stat -p $tmp --log-fd 3 sleep 5 > /dev/null &
done <tmp
with
3>results-$tmp simpleperf stat -p $tmp --log-fd 3 sleep 5 > /dev/null &
done <tmp
.But the flags --logfd , do not work for simpleperf.
The flags used for perf are different from the flags used for simpleperf.
Can anyone suggest a way to access the PMU for all the processes parallely by the simpleperf command.
