### Below shows how to run OProfile on target system ###
# In host Linux
1) Modify .config file of Linux kernel. Add:
CONFIG_PROFILING=y
CONFIG_OPROFILE=y
CONFIG_HAVE_OPROFILE=y
and add "oprofile.timer=1" to CMDLINE, like the following:
CONFIG_CMDLINE="mem=64M console=ttyS0,115200 init=/init oprofile.timer=1"
# In target platform
1) Create the mtab file to /etc/mtab with the following contents
nodev /dev/oprofile oprofilefs rw 0 0
cp /mnt/arm-uc-oprofile/mtab /etc
1) Set binary and library path
export PATH=/mnt/arm-uc-oprofile/bin:$PATH
export LD_LIBRARY_PATH=/mnt/arm-uc-oprofile/lib:$LD_LIBRARY_PATH
2) Setup /dev/oprofile/*
mv /etc/mtab /etc/mtab1
/mnt/arm-uc-oprofile/bin/opcontrol --init
mv /etc/mtab1 /etc/mtab
/mnt/arm-uc-oprofile/bin/opcontrol --init
3) Set up path to Linux kernel image
/mnt/arm-uc-oprofile/bin/opcontrol --vmlinux=/mnt/trunk_ST58200/kernel/linux-2.6.35.12/vmlinux
4) Start profiling
/mnt/arm-uc-oprofile/bin/opcontrol --start
5) Do any thing you want to profile
6) Stop profiling
/mnt/arm-uc-oprofile/bin/opcontrol --stop
7) Read report
/mnt/arm-uc-oprofile/bin/opreport -l
