Hi, I am using Oprofile 0.9.6 with kernel veriosn 2.6.34 running on a PXA270 platform. I am not able to produce the callgraph of a simple user mode program. Is callgraph supposed to work with this configuration? root@ghi270:~ opcontrol --reset root@ghi270:~ opcontrol --no-vmlinux root@ghi270:~ opcontrol --callgraph=5 --start Using default event: CPU_CYCLES:100000:0:1:1 Using 2.6+ OProfile kernel interface. Using log file /var/lib/oprofile/samples/oprofiled.log Daemon started. Profiler running. root@ghi270:~ testop // simple test app // root@ghi270:~ opcontrol --dump root@ghi270:~ opreport -c -l Overflow stats not available warning: /no-vmlinux could not be found. warning: [heap] (tgid:792 range:0x83000-0xa6000) could not be found.
