4) readme.ssh-transparent-login
1. Generate on your LOCAL machine a keypair with:

# ssh-keygen -t rsa (dont type in any password, just keep hitting enter) .

This will generate public/private rsa key pair in the directory of /root/.ssh:

/root/.ssh/id_rsa            (private key)

/root/.ssh/id_rsa.pub        (public key)

2. Make sure your private key resides under /root/.ssh on your LOCAL machine.

3. Also transfer the PRIVATE key to the machine which you want to automatically

login to. Put it under the directory /usr/local/etc.

4. Transfer the PUBLIC key to the machine which you want to automatically login to.

Under the directory /root/.ssh (create it if necessary) concatenate your public key

with the file authorized_keys (create file if needed) .

5. Make sure the authorized_keys on the REMOTE machine is not read or modifiable by

group or others by doing chmod 700 /root/.ssh/authorized_keys.

6. Make sure the /root/.ssh directory on the REMOTE machine is not read or modifiable

by group or others by doing chmod 700 /root/.ssh

7. You may need to enable empty password authentication (need root access) on the

REMOTE machine in the config file sshd_config. Make "Permitemptypasswords yes".

You also need to modify "Protocol 2,1" to "Protocol 2" and modify "HostKey

/etc/ssh/ssh_host_rsa_key" to "/usr/local/etc/id_rsa". Please refer to the attached.

8. Restart /usr/local/sbin/sshd daemon on REMOTE, and you can automatically login with

ssh/sftp without password on LOCAL.

# its license can be downloaded from http://www.gnu.org/copyleft/gpl.html

# This scripts assumes it lives in the contrib directory of the GCC
# source tree, so it will find the testsuite tree from its location.
# If you move it elsewhere, or want to use another testsuite tree, you
# can override the defaults with --srcdir=/some/dir/GCC or
# --testsuite=/some/dir/GCC/gcc/testsuite. If you specify
# --testsuite, --srcdir will be ignored; otherwise, `/gcc/testsuite'
# will be appended to the srcdir.

# You may specify where the binaries to be tested should be picked up
# from. If you specify --prefix=/some/dir, gcc, g++ and gfortran will be
# looked for at /some/dir/bin. Each one may be overridden by
# specifying --with-gcc=/pathname/to/gcc, --with-g++=/pathname/to/g++
# and --with-gfortran=/pathname/to/gfortran. If you specify --without-gcc,
# --without-g++ or --without-gfortran, the test for the specified program
# will be skipped. By default, gcc, g++ and gfortran will be searched in
# the PATH.

# An additional argument may specify --tmpdir=/some/dir; by default,
# temporaries will be stored in the current directory, where the log
# files will be stored.

# The script will interpret arguments until it finds one it does not
# understand. The remaining ones will be passed to `runtest'. A
# double-dash can be used to explicitly separate the arguments to
# `test_installed' from the ones to `runtest'.

# This script should be run in an empty directory; it will refuse to
# run if it finds a file named site.exp in the current directory.

8) For arm-unknown-linux-uclibcgnueabi-* toolchain to run gcc regression test
[mingfeng, 2011-11-07]

In host-Linux (not embedded Linux):
1. Do ssh/sftp transparent login. Please see "readme.ssh-transparent-login".
2. Copy "gcc-4.5.2-sshscp.exp" to /usr/share/dejagnu.
3. Copy "test_installed.remote" to gcc-4.5.2/contrib/.
4. Run script file "run-gcc-4.5.2-sshscp.sh"
5. Generate log
   $ cd gcc-regression-test-20111107
   $ ../gcc-4.5.2/contrib/test_summary > gcc-4.5.2-test_summary.log

### 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
