Hi,
I want to use oprofile for OMAP3530. I am using Ubuntu 9.04 the jaunty jackalope release as host and Code Sourcery's G++ arm gnu linux 4.3-205 version. Ubuntu has linux 2.6.28.13 generic kernel. I have installed oprofile from installation packages. Does it require to configure kernel which is running on target with oprofile enable? I am running my application on Angstrom Demo. Please guide me about to use oprofile for application running on target.

Hello,
Thank for reply. I am using Beaglebaord(OMAP3530) and I am running my application on angstrom Demo kernel. I have checked on Angstrom kernel file system about enable of oprofile "CONFIG_OPROFILE_ARMV7=y". So Now how to configure oprofile so I can do profiling with it on beagleboard. I have also tried to run opcontrol -l command on root and I got output on consol as per uploaded file. Thanks, rach oprofile-l+output.txt

Hello Jean,
I have tried to follow as per e-mail link "http://marc.info/?l=oprofile-list&m=124634769315909&w=2" when I tried to use "opcontrol --vmlinux=/root/oprofile/vmlinux", I got following message. The specified file /root/oprofile/vmlinux does not seem to be valid Make sure you are using the non-compressed image file (e.g. vmlinux not vmlinuz) I have vmlinux-2.6.28-omap1 file under /boot folder. I am using Angstrom Demo kernel Image on Beagleboard. I have used /boot kerenl image. I have run my application after opcontrol --start and before --stop command. I have not set any other event or configuration. I have attached opreport with this reply.opreport+output.txt Thanks, rach

Hello Jean,
As per previous e-mail. I have checked execution time of my application by using gettimeofday() function. It's very less than a second around 0.600 ms. I wan to get precise output. Does it use CPU clock for taking sample ? how much is sampling rate? I have tried gprof also but it's sampling rate is 0.01 sec. I wan to check CPU_CYCLES of my application. Please guide me.

The running time of the application is too small. Since oprofile (and other profiling tools) are statistical tools, you need to run the system for a while in order to get enough samples. Can you run your app in a loop? A few dozens of seconds should be enough.

Hello Jean,
Thanks for guiding me. I will check by copying kernel image into /root/oprofile/vmlinux. Does Oprofile use hardware performance counter to get profiling data? As per you other e-mail reply about to run application in loop, that i will check. I have also tried to run another application which execution time is around 1 sec but I didn't get that into opreport -l output. Does it require to configure other command to get application profiling data? Can we change sampling rate? I have found one doc which is oprofile on RedHat http://www.redhat.com/docs/manuals/enterprise/RHEL-3-Manual/sysadmin-guide/s1-oprofile-configuring.html, in that they have mentioned to change sampling rate. Thanks, Rach

Hi Jean,
I have got my application name in opreport by putting application in loop. I haven't copied vmlinux file into /root/oprofile/vmlinux but I have used opcontrol --vmlinux=/boot/vmlinux-2.6.28-omap1. How to get execution time by using this report?I have attached opreport -l output with reply. Test is my application name, it has taken 4 samples as per report but how to know about execution time? Here it shows CPU speed 0 MHz(estimated), even though OMAP3530 600MHz. what will be reason? Thanks, Rach

Hi Jean,
Thanks. Actually I wan to get execution time of my application. Here I have calculated samples for CPU_CYCLES event so as per configuration it will take sample at 2000000 count. For my application it has taken 4 sample so it took 8000000 count to execute application ....Does it right? Does it any post profiling command or tool to get execution time? I have checked with time <app> but it give in second only and I want to get in microseconds. Thanks for support. rach
