man3/ret_codes.3: Update doxygen generated man-pages for the
pending release.
In the future, we need to use a newer version of doxygen to
generate the pages (1.7 +) because locally installed verions
appear to have a bug.
* src/ctests/nmi_watchdog.c: The nmi_watchdog test should report a
Warning if nmi_watchdog is enabled not an error. (Since we do
work around it, even if performance is likely impacted).
* src/ctests/: Makefile, nmi_watchdog.c: I think the nmi_watchdog
stuff is going to cause us problems down the road.
Thus add a test that will tell users about the issue.
* src/perf_events.c: The nmi_watchdog workaround is needed for
multiplexing too.
The kernel devs don't seem eager to fix this. Until they do,
we'll have to fall back to software multiplexing on recent
kernels that have nmi_watchdog enabled (most vendor kernels).
* src/multiplex.c: Yesterday's coverity fix to make sure the
cleanup and destroy rerturn values were checked ended up
over-writing "retval" in a way that broke the sdsc4-mpx test.
Fix things so that doesn't happen.
* src/: papi.c, perf_events.c, ctests/overflow_allcounters.c: Some
changes for perf_event MIPS support
+ Add __mips__ cases to the format_group, schedulability, and
broken multiplexing bug workarounds, as even new Linux mips
kernels have these bugs + fix overflow_allcounters to work
properly if the MHz value is zero. + Add some debugging to
PAPI_overflow() so that errors are more obvious than just
returning PAPI_EINVAL, which made the previous item a pain to
track down.

* src/components/coretemp/linux-coretemp.c: Fix a possible
directory stream leak in the coretemp component.
reported by coverity checker.
* src/ctests/calibrate.c: Properly free the arrays in calibrate,
introduced by yesterdays coverity fix.
Patch by Will Cohen
* src/components/coretemp/linux-coretemp.c: Fix coretemp to not
fail if /sys/class/hwmon doesn't exist.
* src/components/coretemp/linux-coretemp.c: Patch coretemp to only
free the initialized data in shutdown_substrate (once per
PAPI_init) rather than shutdown (once per thread).
This was causing double free errors.
Patch from Will Cohen
* src/utils/multiplex_cost.c: Fix various calls to PAPI_start() and
PAPI_stop() in multiplex_cost that didn't check the return value.
Took care to try to avoid changing timing measurements. Noticed
by coverity checker.
* src/utils/cost.c: In one case, cost was not checking the return
of PAPI_start()/PAPI_stop(). This change makes it does so, while
being careful not to interfere with the timing that is going on.
* src/ctests/: pthrtough.c, pthrtough2.c: pthrtough and pthrtough2
were not checking the return value for pthread_attr_setscope().
Reported by coverity checker.
* src/ctests/multiplex1_pthreads.c: multiplex1_pthreads was not
checking the return from PAPI_library_init() as flagged by
coverity checker.
* src/ctests/inherit.c: inherit.c wasn't checking the result of the
waitpid() call, as reported by coverity checker.
* src/ctests/clockres_pthreads.c: Check the return of
Reported by coverity checker.
* src/papi_libpfm4_events.c: Fix an actual bug (reported as
deadcode by coverity) where _papi_hwd_ntv_code_to_descr was
appending extraneous ", masks:" strings into an event
None of our utils/ctests exercise this function, which is
probably why the bug wasn't noticed.
* src/: multiplex.c, papi.c: Fix cases where PAPI_*() functions
were called without checking the return for an error.
Reported by coverity.
* doc/Doxyfile.utils: Update version to 4.2.0 for pending release.
* src/multiplex.c: Fix some code that could potentially dereference
a null pointer.
Found by the coverity checker.
* src/papi_vector.c: Remove a dead code case as reported by
coverity. Shouldn't break anything as I can't find anywhere that
vector_print_table() is actually called.
* release_procedure.txt: Update release_procedure to reflect
another file that needs a version number bump. (Doxyfile.utils)
* src/ctests/calibrate.c: Fix some weird code that was sharing a
memory allocation for both double and floats. This was really
ugly and made the coverity checker sad.
Patch provided by Will Cohen.
* src/testlib/test_utils.c: Fix a signed/unsigned comparison bug I
* src/components/coretemp/tests/coretemp_basic.c: Fix the test so
it correctly iterates all of the components.
* src/components/coretemp/: linux-coretemp.c, tests/Makefile,
tests/coretemp_basic.c: Fix a potential memory leak in coretemp
(flagged by coverity).
Also added a test case for coretemp so I can actually test if
these changes are breaking anything.
* src/solaris-ultra.c: Remove const decleration from get_virt_* in
solaris substrate. Vince removed this from papi_vector.h back in
* src/testlib/test_utils.c: Improce the add_two_events() code in
the test library. Before it was possible to overrun a buffer if
none of the potential predefined events were available.
Noticed by the coverity checker.
* papi.spec, doc/Doxyfile, doc/Doxyfile-everything, src/configure,
src/papi.h, src/, src/ Update version to
4.2.0 for pending release.
* src/:, configure,, papi.c, papi.h,
papi_internal.c, papi_user_events.c, papi_user_events.h: Merge in
the user events code , protected by a configure option. (
--with-user-events )
* src/testlib/test_utils.c: We now ensure that test_fail() always
exits. There was some code around that tracked the number of
times test_fail() was called. Remove that, as I think it was
confusing the coverity checker and causing a huge number of false
positives for NULL pointer dereferences.
* src/components/acpi/linux-acpi.c: Some minor cleanups to the acpi
component. It was choking a bit if ACPI didn't provide thermal
information, and also fix a few coverity bugs involving not
checking the result of a dup() call.
* src/testlib/test_utils.c: Another problem with negative numbers,
this time one could potentially be passed to a malloc call.
noticed by coverity
* src/ctests/overflow_pthreads.c: We were indexing an array with a
returned value that could be negative on failure. Add a check to
avoid that.
We're also indexing a per-thread array with an EventSet number,
which sounds suspect, should probably investigate that further.
* src/perf_events.c: perf_events.c was setting variables to -1 and
then potentially using them to index arrays or call close() on
This adds checks to avoid that.
Noticed by the coverity checker.
* src/components/lustre/linux-lustre.h: Include stdint.h and
ctype.h; needed for uint64_t and isspace() respectivly.
* src/components/coretemp/linux-coretemp.c: Fix problem where we
try to manipulate a NULL directory entry.
This fixes a segfault on a Nehalem machine we have here that has
a /sys/class/hwmon/hwmon0 directory without a "device"
* src/components/coretemp/linux-coretemp.c: We were opening a file
but not checking for failure before reading from it.
Flagged by the coverity checker.
* src/components/coretemp/linux-coretemp.c: Both gcc and coverity
were complaining about using an uninitialized pointer. This
makes sure it's not dereferenced if not initialized.
* src/ctests/prof_utils.c: Stop doing unnecessary pointer math in a
print statement.
This was flagged as a problem by the coverity tool.
* src/components/coretemp/linux-coretemp.c: Fix some wrong buffer
sizes in the coretemp component.
Patch from Will Cohen
* src/ctests/sdsc.c: add some extra debug info for sdsc test
* src/papi_hl.c: Add comment to PAPI_num_counters() documentation
about use of PAPI_num_cmp_hwctrs() for component counters.
* src/papi.c: Correct documentation errors for PAPI_strerror.
* src/: configure, Under a no-cpu-counters build,
still build all of the utils. We probably want to rethink some
of the cost util details.
* src/ Remove an unneeded call to "cat". For some
reason it was printing pointless warnings that needlessly
cluttered the buildbot logs.
* src/ctests/: Makefile, multiplex1.c: -lpapi should never be a
dependency. -I.. is missing in makefile
You should be able to cd ctests and do: make <test> or make
Also, added the read after start multiplex case for multiplex1.
This triggers bugs in perf_events systems.
* src/: papi.c, papi_internal.c, threads.c: The multiplex1_pthreads
test was reporting a memory leak.
This is because the test was calling PAPI_unregister_thread()
without destroying its EventSets.
This added change adds code that at unregister_thread time will
destroy any events belonging to that thread.
This works on all the current ctests but I should check some of
the various corner cases not currently tested.
* src/libpfm4/:, lib/pfmlib_amd64.c, lib/pfmlib_common.c,
lib/pfmlib_intel_x86.c, lib/events/intel_nhm_events.h,
lib/events/intel_wsm_events.h: Merge the "conflicts" from the
libpfm4 merge
* src/: threads.c, threads.h: Fix the MEMORY LEAK errors involving
the attach ctests (as seen on buildbot)
These came about when proper multiattach support was added. A
"fake" thread structure is created for each attached process.
These fake thread structures were not being cleaned up at
shutdown, hence the leak.
This fix adds support so at thread shutdown, if we have any
"fake" threads that we created, also shut them down too.
This was tricky, especially dealing with the circular-linked list
the thread info structs are in. This fix seems to work without
negatively affecting the pthread cases.
ctests/multiplex1_pthreads still reports MEMORY LEAK but that
seems to be an eventset issue, not a thread issue, so will be
investigated separately.
* src/: papi.h, papi_fwrappers.c: Add Fortran reference to doxygen
main page.
* src/: papi.c, papi_internal.c, perf_events.c: There has been some
ongoing speculation about what would happen if you enabled
Multiplexing and Overflow at the same time.
It turns out (at least on perf_events) that if you have kernel
multiplexing, the results are what you expect. You get
overflows, but less than in the non-multiplexing case because the
overflow counter isn't being run all the time.
The results for software multiplexing involved a segfault. This
is because in the software multiplexing case the primary EventSet
is a fiction; a set of shadow EventSets are created behind the
scene, and these are the ones used. Therefore when you enable
overflow, the overflow event is attempted to be enabled on the
fictious main EventSet. There are no native events mapped for
it, so overflow tries to access native event array index "-1"
which causes bad things to happen.
This change avoids the issue by catching the "-1" case and
failing accordingly. We should probably decide if we want to
catch the oflo/mpx combination earlier and outright ban it.
I also went through a lot of the code involved adding comments,
as it was really hard following what was going on. This involved
the infamously dense "_papi_hwi_remap_event_position()" function
* src/papi.h: Moved cpu and inherit bits to end of structure for
compat across all 4.x lines. Found by Will Cohen.
As it turns out, I ended up reviewing the CPU_ATTACH changes; I
had not done so before. This functionality actually belongs in
PAPI_set_granularity. A CPU is a natural unit of granularity of
counting, and that value was speced in papi.h a long time ago.
Right thing to do here is leave the current attach stuff but make
it work as part of set_granularity.
Consider that a TODO for 4.3.
* doc/: Doxyfile, Doxyfile-everything: Enable macro expansion in
the doxygen preprocessor step.
Doxygen was not creating docs for the fortran functions and I
believe it is because it was silently choking on our clever
preprocessor abuse; this fixes? that. However, its worth taking
a critical eye to the generated pages again.
* src/: papi.c, papi_fwrappers.c, papi_hl.c: make "* #include" into
"* \#include" so doxygen doesn't treat it as a command.
* src/papi_fwrappers.c: Added all doxygen stubs to the PAPIF group.
* src/ctests/ipc.c: My previous "fix" for the array bounds issue in
ipc.c had multiple embarassing bugs.
Thanks to Will Cohen for noticing. Things should be better now.
* src/: Rules.perfctr-pfm, Rules.pfm_pe: Additionally remove the
now extraneous papi_libpfm_preset definition from the other Rules
files too.
* src/:, Rules.pfm4_pe: The change to make the preset
code generic accidentally ended up defining the build rules for
the file in duplicate places. This fixes that.
* src/: linux-common.c, utils/decode.c: Fix two unused variable
* src/ctests/second.c: We were allocating the "values" array but
never freeing it.
* src/ctests/: sdsc2.c, sdsc4.c: The SDSC tests could walk off the
end of an array.
* src/ctests/overflow_twoevents.c: We could potentially access
outside an array boundary in overflow_twoevents.
* src/ctests/ipc.c: ipc was also abusing array boundaries.
* src/ctests/flops.c: The flops.c ctest was abusing the notion of C
arrays, by writing INDEX*INDEX values to mresult[0][i], I suppose
"knowing" that this would fill in the whole array. Fix things to
use an additional iterator.
* src/ctests/byte_profile.c: The coverity checker rightly points
out that the last argument to strncat should be buffersize-1.
* src/ctests/: exeinfo.c, shlib.c: Coverity flagged that there were
some tests that had no effect. In particular the are tests that
the pointers are non-null. However, they are arrays rather than
pointers. This patch make it clear that arrays are being used in
the code.
Patch from Will Cohen at redhat
* src/ctests/clockcore.c: This is a relatively minor patch that
ensures that all the allocated memory is initialized to zero
before it is used. Coverity might not be smart enough to
determine whether the test actually wrote into all the locations
because of the case statement. This is make it easier for
coverity to determine that the memory has been initialized.
Path from Will Cohen at redhat.
* src/multiplex.c: Coverity scan showed that MPX_cleanup() function
was blindly accessing a value through a pointer and then checking
to see that the pointer was null. This patch makes sure that the
pointer is checked before it is used.
Patch from Will Cohen at redhat.
* src/ctests/: pthrtough.c, pthrtough2.c: Coverity found that the
sizeof argument for pthrtough2.c and pthrtough.c was using
sizeof(pthread *) rather than sizeof(pthread). This patch fixes
that problem.
Patch from Will Cohen at redhat
* src/papi_internal.c: This change moves the setting for default
domain to be enforced at eventset add time, rather than eventset
creation time.
This fixes some problems seen when multiplexing.
The patch was provided by Phil Mucci.
* src/pmapi-ppc64.h: One more file that is no longer needed.
* src/: configure,, perfctr.c, pmapi-ppc64_events.c,
ppc64_events.c: Clean up the now not-needed pmapi-ppc64_events.c
* src/:, aix.c, aix.h, configure,,
papi_libpfm_presets.c: Finalize the merge of the preset code.
* src/aix.c: Fix a missing include.
* src/: aix.c, configure, Move more code to its
proper place.
* src/: aix.c, configure,, pmapi-ppc64.c,
pmapi-ppc64_events.c, ppc64_events.c: Move the
ppc64_setup_native_table() routines out of the preset code.
This is complicated, as there are two very similar routines
setup_ppc64_native_table() used by AIX/pmapi and
ppc64_setup_native_table() used by perfctr
These could probably be merged too, but this is definitely not
the time.
* src/: aix.c, papi_libpfm_presets.c, pmapi-ppc64_events.c: move
pmapi_find_full_event to be _aix_ntv_name_to_code() as it
probably always should have been.
* src/: papi_libpfm_presets.c, papi_setup_presets.h,
pmapi-ppc64_events.c: Make papi_libpfm_presets more generic by
calling _papi_hwi_native_name_to_code() rather than a
substrate-specific call.
* src/: aix.c, papi_libpfm_presets.c, pmapi-ppc64_events.c: I was
mainly doing this to aid debugging, but now the
papi_libpfm_presets.c file and pmapi-ppc64_events.c file are
close enough to being identical I might try to merge them.
* src/: papi_libpfm_presets.c, pmapi-ppc64_events.c,
ppc64_events.h: The files are almost the same now.
* src/: papi_libpfm_presets.c, pmapi-ppc64_events.c: More making
these files the same, including some memory leak fixes that made
it to the former but not the latter.
* src/: papi_libpfm_presets.c, pmapi-ppc64_events.c: Tracking down
problems on AIX can be a bit of a pain because
papi_libpfm_presets.c and pmapi-ppc64_events.c are almost (but
not quite) the same. This change makes the files more similar,
mostly by cleaning up whitespace and normalizing comments and
debugging statements between the two.
* src/pmapi-ppc64_events.c: Ugh, obvious typo in that last commit.
* src/pmapi-ppc64_events.c: In ppc64_setup_gps() the current code
sometimes walks off the end of the group array and trashes
unrelated memory.
Until we work out the proper fix, this prints an error message
and stops the loop before memory is corrupted.
* src/papi_data.h: No one seems to remember the last time this file
was used, so let's remove it.
* src/ Remove the "u" option to the "ar" command that
links libpapi.a, as it was breaking the build on MIPS.
This *shouldn't* break anything, but messing around with "ar"
options can be potentially dangerous. I'll double-check the
non-Linux builds.
* src/libpfm4/lib/: Makefile, pfmlib_mips_priv.h,
events/intel_nhm_events.h, events/intel_wsm_events.h: Fix up the
"collisions" from the libpfm4 import
* src/ We would like to use parallel make on packages
to speed things up. However, when this was tried with papi the
"make -j4" failed
( I took a
look through the code and found that some of dependencies were
not quite right. Turns out that $(papiLIBS) is substituted during
the configure, but it isn't available for the actual make.
Attached is the patch that ensures that the $(LIBS) are built
before utils and tests.
Patch from Will Cohen <wcohen at>
* src/ Modify so that you can set the
VALGRIND command externally via environment variable without
having to edit itself.
Also adds Date and cpuinfo information to the beginning of results. This can help when run output
is passed around when debugging a problem.
Patch from Phil Mucci
* src/: configure, If we have no Fortran compiler
available, then our current build system tries to build the
Fortran examples with an empty compiler string which just
generates strange errors.
This patch changes F77 to be "echo" which at least avoids the
errors. The proper fix is probably just not to build the Fortran
samples if no compiler is available.
Patch from Phil Mucci
* src/papi_libpfm4_events.c: The build on power6 was warning in a
DEBUG statement because sizeof() returns an int rather than a
long. So use a cast to avoid this.
* src/perf_events.c: The move to use pid_t for pid values caused
warnings on a --with-debug build due to the lack of a way to
print a pid_t value without a cast.
This fix adds the proper casts.
* src/papi_libpfm4_events.c: Rename the "perfmon_idx" structure
field the more evocative "libpfm4_idx" value.
Patch from Phil Mucci
* src/ctests/all_native_events.c: Fix problem where we were passing
a pointer to an EventSet rather than the actual EventSet number
to PAPI_cleanup_eventset().
Also include some of the cleanups from Phil Mucci's MIPS tree.
* src/: perf_events.c, perf_events.h: Make the perf_event ctl
structure have more explicit data types.
Patch from Philip Mucci
* src/: cycle.h, linux-common.c, linux-context.h, linux-lock.h,
linux-timer.c, mb.h, papi.h: Add bare minimal MIPS74k support,
enough to compile.

Problem reported by coverity tool, via Will Cohen
* src/linux-common.c: The coverity tool noticed that we allocate
and populate a cpu node info structure, but we never pass any
info on this structure outside of the cpu detection routine, in
effect leaking the allocation.
For now just comment out this code as it is not used by anyone.
Problem reported by coverity tool, via Will Cohen
* src/: papi.c, papi_libpfm3_events.c, perfctr-x86.c: The coverity
checker was reporting we forgot to fclose() /proc/cpuinfo in
The bigger question, is why were we unconditionally trying to
open /proc/cpuinfo in generic code in papi.c anyway?
Turns out it was to set the event masks properly for itanium and
The platform code sets CPU vendor and family for us though, so if
we just make the event mask code use those values then we don't
have to open cpuinfo. This also means that non-Linux users with
the misfortune of running on a P4 might actually work too.
* src/: papi_internal.c, papi_libpfm_presets.c: In various places
we were using MAX_COUNTER_TERMS (defined by substrate) rather
than PAPI_MAX_COUNTER_TERMS (a papi predefined event define).
This could cause buffer overruns.
This fixes things, though really we shouldn't have such similar
names for different defines.

dereferencing a NULL pointer in MPX_stop()

dereferenced as NULL in PAPI_start()
Reported by coverity tool, via Will Cohen
* src/papi_events.csv: Update the AMD Family 14h (Bobcat)
pre-defined events.
It turns out they are different enough from 10h that they need
their own category.
In going through the Fam14h BKDG it turns out that Bobcat has a
really nice set of events available, especially for
Floating-Point/SSE but also memory bandwidth.
With this change, all of the ctests pass on a Bobcat machine.
* src/: configure, Recent Ubuntu versions use the ld
flag --as-needed by default.
This breaks the PAPI configure step for the libdl check, as the
--as-needed flag enforces the rule that libraries (in this case
-ldl) must come after the object files on the command line, not
The fix for this is easy, the libdl check was wrongly sticking
-ldl in LDFLAGS rather than in LIBS. Putting it in LIBS makes
things work as expected.

* src/papi_libpfm4_events.c: The libpfm4 code was doing a full call
to pfm_get_os_event_encoding() during every call to
This is unnecessary, as we can call pfm_get_os_event_encoding()
once at event creation time and cache the results. There's no
need to call it each update_control_state(), as that is called
during PAPI_start() and thus relatively time critical.

These weren't being built when --with-no-cpu-counters was
enabled, so the PAPI build was breaking when that was enabled as
well as a component.

* src/: papi.c, papi_protos.h, papi_vector.c, papi_vector.h,
components/README, components/cuda/linux-cuda.c,
components/cuda/linux-cuda.h: Deleted function pointer
destroy_eventset from the PAPI vector table, and added
cleanup_eventset instead. PAPI_destroy_eventset() requires an
empty EventSet. Hence, usually PAPI_cleanup_eventset() is called
before PAPI_destroy_eventset(); which also sets the CompIdx to
-1. This means, PAPI_destroy_eventset() won't have any knowledge
about components. However, in order to disable CUDA eventGroups
and to free perfmon hardware on the GPU, knowledge about the CUDA
component index is required. Hence, I replaced
CUDA_destroy_eventset() with CUDA_cleanup_eventset() in the CUDA
component. NOTE: Please make sure you call
PAPI_cleanup_eventset() before calling PAPI_shutdown().
* src/: papi_protos.h, papi_vector.c, papi_vector.h,
components/cuda/linux-cuda.c, components/cuda/linux-cuda.h: CUDA
component is now thread-safe. Starting in CUDA 4.0, multiple CPU
threads can access the same CUDA context. This is a much easier
programming model then pre-4.0 as threads - using the same CUDA
context - can share memory, data, etc. Note, it's possible to
create a different CUDA context for each thread, but then we are
likely running into a limitation that only one context can be
profiled at a time.

* src/perf_events.c: The warning I had print on nmi_watchdog being
found was a bit much, make it a SUBDBG() call instead.
I do wish there were a way to notify the user more visibly,
because losing a counter (when you might only have 4 total to
begin with) is a big deal, and most Linux vendors are starting to
ship kernels with the nmi_watchdog enabled.
* src/: linux-common.c, linux-common.h, perf_events.c: On newer
Linux kernels (2.6.34+) the nmi_watchdog counter can steal one
of the counters, reducing by one the total available.
There's a bug in Linux where if you try to use the full number of
counters on such a system with a group leader, the
sys_perf_open() call will succeed only to fail at read time.
(instead of the proper error code at open time).
This patch attempts to work around this issue by detecting if a
watchdog timer is being used, and in that case re-use the
