Hi Linaro Dev team,
I am trying to debug some scheduler changes on my new QUalcomm snapdragon development board. To debug it further, i have cross compiled the idlestat and tried to run for collecting traces. But it shows segfault right after starting it with `idlestat --trace -f /sdcard/mytrace -t 10 -p -c -w -- cyclictest
Pagefault logs can be found here [1] . Any suggestions will be much appreciated.
Hi,
thanks for reporting the issue.
Could you compile idlestat with the debug info, set the core limit (ulimit -c unlimited), run the idlestat again ? That will generate a 'core' file which we can exploit to do further investigation.
Otherwise run it with 'gdb' and then give the portion of code where the segfault occurs.
