Hello List,
I am trying to run Oprofile 0.9.5 on ARMv6 based target.
The CPU on target is S3C64100 a ARMv6 processor. I have compiled the kernel 2.6.21 with following config options
...
CONFIG_ARMC6=y
CONFIG_ARM11_CORE=y
...
...
CONFIG_PROFILING=y
CONFIG_OPROFILE=y ...
...
Oprofile 0.9.5 and libpopt was compiled. The compilation and installation went through smoothly. Have I missed any thing while compilation? Or the libpopt was incompatible with oprofile 0.9.5.
I have used following sequence of command and setup for profiling.
Setup:
opcontrol --no-vmlinux --image=all --callgraph=20 --setup
Start:
opcontrol --start
The Oprofile Daemon start without any error.
After letting it run for couple of minutes, profiling was stopped.
opcontrol --stop
Then dumped the data with
opcontrol --dump
The result with
opreport --callgraph.
The opreport command gives following output
error: no sample files found: profile specification too strict ?
The kernel boot message detects the ARMv6 with following message
Oprofile: using ARMv6
The /dev/oprofile is mounted.
Your help will be highly appreciated.
Thanks,
Arabinda

Thanks Maynard for the reply.
I have tried as you have advised. It is happily taking the detault path /var/lib/oprofile.
The file system is mounted through the NFS on host. Can this be an issue?

Maybe you can try start oprofile with timer mode in case this processor is not support well yet.

ARMv6 has been supported in oprofile userspace since 0.9.3, so I would certainly expect kernel 2.6.21 is new enough to support the kernel portion. *Richard*, do you have any words of wisdom for Sam? My experience running on embedded systems is nil. -Maynard > > -Sam > > On Thu, Nov 5, 2009 at 12:00 PM, Arabinda Verma <arabinda.verma@...>wrote: > >> Thanks Maynard for the reply. >> >> I have tried as you have advised.
