Running operf on NVIDIA Jetson TX2

Hi *,

I am trying to run operf(oprofile.sourceforge.net) system profiler on NVIDIA Jetson TX2 and the first thing it checks is to see the number of online CPUs by checking this path:

/sys/devices/system/cpu/cpu0/online

Since this path isn’t available on my Jetson TX2, the operf throws runtime error.

I did some research on how to enable it and It looks like I don’t have CPU HOTPLUG enabled in my kernel. I also checked these two post :

  1. https://devtalk.nvidia.com/default/topic/1000345/two-cores-disabled-/
  2. https://devtalk.nvidia.com/default/topic/762257/cpu-cores-offline-had-to-manually-enable-/

As mentioned in the 2nd link, I also don’t have “cpuquiet” in my Jetson TX-2.

How do I enable “cpuquiet” or have /sys/xxx/cpu0/online ?

Here is my system information:

Ubuntu 16.04 LTS
L4T Version: L4T R28.2
Jetpack 3.2

Reason for using operf instead of NVIDIA System Profiler:
I have used NVIDIA System profiler and I wasn’t able to profile all the process running on my system. I am not just interested in the timeline view( which we get info on all the running process), but looking for hotspot breakdown in all the processes running in my system. I tried annotating my code using nvtx markers but it only shows those markers in the process that I attach in the System Profiler. If there is a better way to do this, let me know!

Please let me know if anyone knows how to fix this issue!

Thanks
Sri

Use the tegra kernel that comes with the driver package.

@generix: Thanks for getting back!

I am using Jetpack 3.2 and I thought it comes with the tegra kernel. I also cross-checked to see the version of the kernel I am using. It is 4.4.38-tegra!

Can you tell me more if I am missing something here!

Thanks
Sri

Then that’s strange, CPU_HOTPLUG is compiled into the tegra kernel. Can you attach a dmesg output?

I actually have 3 TX2 and I don’t have it any of those!

Here it is:
