Durga, you're replying to the wrong thread.
Thanks for the reply.
I can able to run oprofile on the target(ARM V7-CA9) in timer mode.
The problem of Bad magic number is because of the JFFS2 file system.So I mounted
usb on the target and colleted the sample on the target.
I am able to analyze the sample on the target.But for analyzing the samples on
the host I am doing the follows process.
I mounted the USB to /var/lib/oprofile -- so the sample will be collected
directly to USB
After the I am running oparchieve on the target
*oparchive -o /var/lib/oprofile/durga/*
I am doing opimport on the host PC
*# opimport -V -a /media/Pen_drive/durga/ -o /home/durga/oprofile/
error: must specify exactly 1 input file
*I am getting the above error always.*
*How to analyze the sample collected in the Host PC after collecting the samples
in Pen drive from target*?
*Your *help* will *be* warmly received.
Regards,
Durga Prasad

max/min_interval are through all the code always unsigned. I don't
know how min/max_sampl_rate in struct hws_qsi_info_block is spec'ed,
but there it is unsigned too.
So the best would be to return qsi.min/max_sampl_rate in
hwsampler_query_min/max_interval() directly with no error codes as
unsigned longs and to change the code in oprofile_hwsampler_init() to
check for null. Both functions hwsampler_query_min/max_interval()
could be moved to hwsampler.h as static inline functions. This makes
the code also easier.
This patch does not handle the null value case and the data truncation
by casting from unsigned to singed is not fixed.
