Detect vmlinux file with no symbols

Some platforms include a /boot/vmlinux-`uname -r` file that has
no symbols. The oprofile testsuite currently assumes that such
a file does have symbols and will fail horribly if it finds such
a stripped file. This patch makes the testsuite more robust by
doing some basic checking of the file for validity.

Fix ocount/operf tests when cpu type 'timer' is detected

If running the full testsuite (i.e., 'runtest --tool=oprofile'), the
oprofile-opcontrol runs before the operf tests. However, the exit proc
does not run until we're completely finished, so opcontrol_exit will
not have been called to do the deinit. Some newer processor models
are not supported by opcontrol except in timer mode, so running
opcontrol results in /dev/oprofile/cpu_type being set to 'timer' by
the oprofile kernel module. If operf/ocount are run in such a situation,
they detect the "timer" mode and exit with a message telling the user
to run 'opcontrol --deinit'. This causes the ocount and operf tests
to fail when we attempt to get the operf or ocount version.

The change made with this patch is to try to run 'opcontrol deinit'
(assuming we are root user) if the initial attempt to get the tool version
failed; then we'll try again to get the version for the ocount or operf tool.
If we're not user, we'll print a big message asking the user to
try 'opcontrol --deinit'.

Testsuite, add tests for kallsyms, callgraph and debug info options

Add a test to verify that the kernel symbols were properly found in
/proc/kallsyms if the vmlinux file was not used.

Add test to verify /proc/kallsyms can be read.

Add test to verify the output format when the --debug-info and --symbols
options are used with opreport.

Add test to verify the --callgraph option at least produces some results.

The do_test procedure in oprofile-single_process-run.exp is moved to
lib/operf_util.exp and renamed do_single_process_test since it is now used
by tests in oprofile-operf-run.exp and oprofile-single_process-run.exp.

The do_test procedure in oprofile-operf-run.exp is also moved to
lib/operf_util.exp and renamed do_system-wide_test to keep the organization
of the test files similar.

oprofile-tests: Fix error message "Do not know how to handle version {1.0.0git}"

This patch fixes the message "Do not know how to handle version {1.0.0git}".
The current code requires that each new major version be added to the
case statement for versions greater then 0.5. Apparently, versions prior
to 0.5 were not supported by the testsuite for some now unkown reason. This
patch creates a specific case to handle the pre 0.5 versions, the 0.5 version
and all newer versions are handled by the default case. The case for the
pre 0.5 version of profile will simply print a message saying the version
is not supported. The case for version 0.5 is unchanged. The default
will handle all newer versions so this issue doesn't have to be continually
fixed with each major version change.

Add test for the ocount tool

The patch adds support for two additional testsuites for testing the ocount
tool. The first testsuite runs a series of tests on the ocount tool. The
tests include:

- each event generates non-zero counts
- counting for each event for an interval of n seconds, 2*n and 4*n scale as
- the sum of the counts for each event in user mode only, kernel mode
only match counting in user and kernel mode
- the output using the brief output format is verified

The above tests are run when the tool "oprofile" or "oprofile-ocount" are run.

The second testsuite includes the additional test:

- counting cycles for an interval of n seconds matches n*proc_frequency

This testsuite is only run when the tool "cycle-check-ocount" is specified.
The testsuite checks the event count against the reported CPU frequency which
may or may not be the actual operating CPU frequency. The reported frequency
and the actual frequency may differ if the CPU is running in the Intel "turbo"
mode or at a lower frequency for thermal management. The user may need to
manually verify any test failures based on the actual operating CPU frequency
not the reported CPU frequency.

Allow opcontrol tests to identify Intel Ivy Bridge and Sandy Bridge processors

For all the Intel processors that provide architected events reading
/dev/oprofile/cpu_type just returns i386/arch_perfmon. To get a more

model number in /proc/cpuinfo. This patch adds recognition of Intel

Adjust events for IBM POWER7 processor

The POWER7+ processor (which has the same events as POWER7)
has a much larger cache than POWER7. When running the
testsuite on POWER7+, the PM_BR_PRED_CCACHE event was not
being seen at all. I removed this event from the list of
events to monitor for since cache-related events are not
easy to deterministically predict for unknown processor
types. I also adjusted down the number of certain other
POWER7 events to help ensure the testing would "see" some
samples for those events.

Fix tcl workload symbol checking

Intermittently, the operf system-wide and operf single-process
tests fail after running the tcl workload (which executes a dd
command) and attempting to find the string "/bin/dd" in the
opreport output. The reason for this is two-fold:
- operf will profile child processes that a parent process will
fork/exec, but will terminate the profiling once the parent
process exits.
- The testsuite/workloads/tcl_src/workload.tcl script execs
the dd command as the last statement in the script and then

Considering the two facts stated above, it's clear that profiling
of the dd command may or may not occur, depending on timing.
Once the parent tcl process exits, operf will detect the parent
exiting and will shutdown profiling. Some samples may have been
collected for the dd command before this shutdown occurs, but maybe

To avoid this timing issue, this patch simply changes the symbol
we check for in the tcl profile output from "/bin/dd" to "libtcl".

also moves the function to lib/op_util.exp so it can be called by

OProfile testsuite, fix perf kill command

The operf user tool expects to get a kill -SIGINT signal. However
the SIGINT signal can not be sent from a script, it must come from
the command line. Hence the pkill -P command was used to kill the
parent and children processes. A bug was found in that the pkill
command kills operf without letting it completely finish the data
processing and exit cleanly. This issue actually was found when
testing a patch that is currently under development to check for
specific symbols. The kill -INT signal can be sent from the script
and is properly caught by operf. When operf catches the INT signal
it shuts down cleanly rather then exiting immediatly. This patch
fixes the current kill command to make sure operf exits cleanly.

OProfile testsuite, change operf version check fail to warning

This patch changes the operf version test failure to a warning instead
of a failure. Also, the user message that is printed is changed to
be more explicit that the user tool operf is not supported rather then
using the term "system" which could be interpreted as meaning the
kernel. The patch specifically addresses systems with a perf enabled
kernel but an older (OProfile 0.9.7 or older) user space tool that
does not have support for the new operf user interface.

OProfile testsuite, add operf support to the testsuite

This patch adds support for the basic testing of the new
operf user interface. It leverages the existing event
tables for the various processors. OProfile has its own
kernel support for the names of the processors. This
information is only available when the OProfile kernel
module is loaded. The operf support gets the CPU name from
the ophelp command instead.

The patch also fixes an error in the existing opcontol testsuite.
Specifically, the test for the string "opcontrol error:" will always
fail because the output from the command does not include the word
"opcontrol". Removed "opcontrol" from the test string.

Added commands to the opcontrol testsuite to make sure the
daemonrc file is removed. This is necessary to ensure there are no
extraneous settings, for example filter settings, that will cause errors.

Trailing blanks on five lines in the existing files were removed.

The testsuit for testing OProfile using the opcontrol interface
has been renamed to oprofile-opcontrol. The new testsuite to
test OProfile using operf is called oprofile-operf. To run both
testsuites, use the testsuite oprofile. Specifically the commands
to run the testsuites are:

runtest --tool oprofile-opcontrol // test opcontrol interface

runtest --tool oprofile-operf // test operf interface

runtest --tool oprofile // test both interfaces
