* src/Rules.pfm_pe: The --with-bitmode parameter was not being
passed along to libpfm3, so it was not possible to build
perf_event PAPI on non-default bitmodes. This change passes
along the $(BITFLAGS) value to the libpfm3 make invocation.
* src/: papi_pfm_events.c, papi_pfm_events.h, perf_events.c: The
perf_events code was using __u64 instead of uint64_t and this was
causing a warning when compiling for 64-bit Power.
* src/libpfm-3.y/lib/amd64_events_fam15h.h: Added Robert Richter's
patch with a few new events for AMD Family 15h.
2011-05-06
* INSTALL.txt: Load the 'gcc' module not 'gnu' module for Cray.
* INSTALL.txt: Update the install instructions for Cray XT and XE
systems.
* src/ctests/: multiattach.c, multiattach2.c: Make the multiattach
and multiattach2 failures into warnings.
I have a proposed fix that makes the failures go away, but it has
not been tested much and also causes some new fcntl() error
messages under perfctr.
So temporarily make the tests only warn for the release and I'll
work on a proper fix for after. The behavior in these tests has
been broken for a long time so it is not a recent regression.
* src/papi_memory.c: Band-aid for the leak debugging statement in
papi_memory.c on NO_VARARG_MACRO systems. (aix currently)
2011-05-05
* src/ctests/multiattach.c: Had the division backwards on the
validation.
* src/ctests/multiattach.c: Update the multiattach test to fail if
the results aren't in the proper ratio. This was failing on
perf_event kernels but since the results weren't checked it was
never reported as an error.
* delete_before_release.sh: delete cvs2cl.pl before release
* ChangeLogP413.txt: First cut change log for the 4.1.3 release.
Nothing's frozen yet...
* cvs2cl.pl: Perl script to generate change logs. Keeping it with
the project makes life easier.
* INSTALL.txt: Change INSTALL to reflect that we support power7.
* src/Makefile.in, src/configure, src/configure.in, src/papi.h,
doc/Doxyfile, doc/Doxyfile-everything, papi.spec: Modfy version
number for pending release: 4.1.3.0
2011-05-03
* src/: papi_internal.c, papi_internal.h, sys_perf_event_open.c,
ctests/attach2.c: Cleanup the _papi_hwi_cleanup_eventset()
function in papi_internal.c
This function was re-using existing functionality to remove one
event at a time before cleaning out the eventset. This is not
strictly necessary and was breaking on perf_event eventsets that
were attached to finished processes, as a call to
update_control_state() would close/reopen the perf_event fd,
failing when the finished process went away after the close.
The new code removes all events from the eventset in one go
before calling update_control_state.
The change here also updates code comments as necessary, as some
of the code in papi_internal.c can be a bit obscure.
It also updates some of the comments in ctests/attach2.c to give
better debugging info.
2011-04-28
* src/threads.c: Uncomment the actual signal passing functionality
in _papi_hwi_broadcast_signal
* src/papi_debug.h: Include files added to papi_debug.h
* src/components/README: Added detailed instructions on how to
build PAPI with the CUDA component
2011-04-27
* src/threads.c: Move an escape test to the outer loop in
_papi_hwi_broadcast_signal.
This cleans up an infinite loop where before we would only break
out of the component look, not the thread list walking loop.
* src/: papi.c, papi_internal.c, papi_internal.h, papi_protos.h:
Clean up papi_internal.c so that functions not used outside are
marked static.
* src/: papi_pfm_events.c, papi_preset.c, pmapi-ppc64_events.c:
papi: Fix some memory leaks
Signed-off-by: Robert Richter <robert.richter@amd.com>
* src/perf_events.c: papi: Make functions and variables static in
perf_events.c
All this functions and variables are not used outside
perf_events.c. Making them static.
Signed-off-by: Robert Richter <robert.richter@amd.com>
* src/papi_pfm_events.c: papi: Fix crash in error handler for
pfm_get_event_code_counter()
Signed-off-by: Robert Richter <robert.richter@amd.com>
* src/utils/native_avail.c: papi: Fix error check in native_avail.c
Signed-off-by: Robert Richter <robert.richter@amd.com>
2011-04-26
* src/libpfm-3.y/: include/perfmon/pfmlib_amd64.h,
lib/pfmlib_amd64.c: AMD architectural PMU could not be detected
for family 15h as there was a strict check for AMD family 10h.
Enabling it now for all families from 10h.
Signed-off-by: Robert Richter
* src/libpfm-3.y/lib/amd64_events_fam15h.h: There is no kernel
support for AMD family 15h northbridge events, disabling them in
libpfm3 to not report them as available native events.
Patch from Robert Richter
* src/: configure, configure.in, linux-common.c: Add some extra
debug messages for better tracking of the --with-assumed-kernel
configure option.
2011-04-25
* src/: configure, configure.in, linux-common.c: Add a new
configure option: --with-assumed-kernel=<ver> This allows you
to specify a kernel revision to (instead of being autodetected
with uname) for perf_event workaround purposes. With this you
can force PAPI to not use workarounds on kernels with
backported versions of perf_event features.
2011-04-19
* src/: Makefile.inc, configure, configure.in, papi_debug.h,
papi_internal.h, sys_perf_event_open.c: Add debugging to
sys_perf_event_open.c to show exactly what values are being
passed to the perf_event_open syscall.
2011-04-18
* src/: run_tests.sh, ctests/attach2.c, ctests/attach3.c: Fix for
finding attach_target with execlp to search the path.
2011-04-14
* src/: Rules.pfm, configure, configure.in, linux-ia64-pfm.h,
linux-ia64.c, linux-ia64.h, perfmon-ia64-pfm.h, perfmon-ia64.c,
perfmon-ia64.h, perfmon.h: Rename the linux-ia64-* files to be
called perfmon-ia64-*
This is a more descriptive name, and makes it more obvious what
the files are for.
* src/libpfm-3.y/: include/perfmon/pfmlib_amd64.h,
lib/pfmlib_amd64.c, lib/pfmlib_amd64_priv.h: Patch to have
libpfm3 use 6 counters on Interlagos.
Patch provided by Robert Richter
* src/linux-memory.c: Fix the POWER cache detection routines to
work properly on POWER7.
Patch provided by Corey Ashford
* src/: configure, configure.in: Have configure check for ifort if
gfortran, etc, not found.
Patch by Gary Mohr
* src/ctests/johnmay2.c: Update the validation message on the
ctests/johnmay2.c test to be less confusing. Also add some
comments to the source code.
Problem reported by Steve Kaufmann.
2011-04-13
* src/ctests/: multiattach2, multiattach2.c: Remove the
accidentally added ctests/multiattach2 and add instead the proper
ctests/multiattach2.c
* src/Makefile.inc: components_config.h is cleaned out with make
clobber, not make clean this should fix the build bot issues.
* src/ctests/: Makefile, attach3.c, multiattach.c, multiattach2,
zero_attach.c: Minor typos in comments. Discovered another bug in
attach code demonstrated by multiattach2. You cannot have an
eventset running that is self counting as well as one that is
attached. PAPI thinks that both are running and throws an error.
* src/perf_events.c: We must update the control state after
attaching for perf_events, zero_attach now passes
* src/ctests/: Makefile, attach2.c, attach3.c, do_loops.c: This
commit adds testing of attaching to fork/exec'd executables.
zero_attach and multiattach just test forks. This also modifies
do_loops.c to be able to generate a test driver when
-DDUMMY_DRIVER is defined so we can use it to generate flops as a
sub process.
Attach2 and attach3 have one important difference.
Attach3 does a 'assign component' before attaching and then
adding events. Attach2 does not assign a component and thus
should inherit the default component.
The current bug in PAPI is that: * The default component is not
assigned until you add an event. * However, attaching an
eventset without events is perfectly valid, but we get an error.
Possible solution is that the default component should be
assigned at create time.
2011-04-12
* src/ctests/multiattach.c: Make sure the two processes compute
different numbers of flops to test attach
2011-04-05
* src/power7_events.h: Turns out Maynard Johnson answered my
questions about the native_name enum back in December. ( this is
a correct version of the events file )
As I found out, the AIX substrates do not use the native_name
enum. But a hypothetical perfctr build would.
2011-04-04
* src/Makefile.inc: Clear out the components_config.h file on make
clobber
* src/: aix.c, power7_events.h: Initial support for power7 aix, the
events file is a copy of power6_events.h with the number of
groups changed. The native_name enum is unchanged, but unused?
2011-04-01
* src/configure.in: Commited wrong configure.in
* src/: configure, configure.in: Clean up setting bitmode flags for
non-gcc (xlc in this case) compilers.
* src/papi_events.csv: Change the Nehalem PAPI_FP_OPS event from
FP_COMP_OPS_EXE:SSE_SINGLE_PRECISION+FP_COMP_OPS_EXE:DOUBLE_PRECISION
to FP_COMP_OPS_EXE:SSE+FP_COMP_OPS_EXE:X87
The new event gives the same results as the previous one, with
the added benefit of also counting 32-bit compiled x87 fp ops
properly.
More detailed analysis can be found here:
http://web.eecs.utk.edu/~vweaver1/projects/nehalem-fp_ops/
2011-03-28
* src/utils/multiplex_cost.c: Turns out that getopt_long isn't as
standard as I had hoped.
Convert multiplex_cost to use only getopt. -s disables software
multiplexing -k disables kernel multiplexing
2011-03-25
* src/: configure, utils/Makefile, utils/multiplex_cost.c,
configure.in: Multiplex_cost utility.
* src/utils/: Makefile, cost.c, cost_utils.c, cost_utils.h: Split
off the statistics functions from cost.
2011-03-22
* src/: run_tests_exclude_cuda.txt, run_tests.sh: Exclude some
fork/thread tests from fulltest that won't run with CUDA (reason:
cannot invoke same GPU from different threads)
2011-03-21
* src/utils/cost.c: Add a test for DERIVED_[ADD | SUB ] events to
papi_cost.
2011-03-18
* src/components/cuda/linux-cuda.c: all_native_events ctest failed
when CUDA Component is used. Reason: removing cuda events from
the eventset is currently not supported. According to the NVIDIA
folks this is a bug in cuda 4.0rc and will be fixed in rc2. Note
also, several fork and thread tests fail since it's illegal to
invoke the same GPU device from different processes / threads. We
need a mechanism that allows us to run tests for the CPU
component only.
2011-03-15
* src/utils/cost.c: Add a test case to cost util, look for a
derived-postfix event and if found, give timing information for
read calls to it.
This is just a first run at the test, Core2 and AMD have
candidate events and the test runs, but that is the extent of my
testing so far.
2011-03-11
* src/components/: README, cuda/Makefile.cuda.in, cuda/Rules.cuda,
cuda/configure, cuda/configure.in, cuda/linux-cuda.c,
cuda/linux-cuda.h: Added CUDA component, a hardware performance
counter measurement technology for the NVIDIA CUDA platform which
provides access to the hardware counters inside the GPU. PAPI
CUDA is based on CUPTI support - shipped with CUDA 4.0rc - in the
NVIDIA driver library. In any environment where the CUPTI-enabled
driver is installed, the PAPI CUDA component can provide detailed
performance counter information regarding the execution of GPU
kernels.
* src/components/: coretemp/linux-coretemp.c,
lustre/linux-lustre.c: Add some missing includes to components.
Thanks to Will Cohen for reminding us warnings matter. :)
* src/: configure, configure.in, perf_events.c: The SYNC_READ
workaround in perf_events.c was being handled at compile time,
rather than at run-time like all of our other workarounds.
Change it to be like our other kernel-version related
workarounds.
2011-03-09
* src/ctests/multiplex1_pthreads.c: Between 4.0.0 and 4.1.0 a
pthread_exit() call was added to ctest/multiplex1_pthreads.c that
caused the test to exit partway through the test and without
doing a proper PASS/FAIL result.
This changeset backs out that change, though the original change
was marked as a memory leak fix so a different fix may be needed.
Reported by Steve Kaufmann
* src/linux-timer.c: Add missing header needed by
--with-virtualtimer=times build.
Reported by Steve Kaufmann
2011-03-01
* src/: papi_pfm_events.c, perf_events.c: Fix broken Linux/PPC
build caused by my pfm_events code movement changes.
2011-02-25
* src/: papi_pfm_events.c, papi_pfm_events.h, perfctr-x86.h: My
changes yesterday broke the perfctr build. This should fix it.
2011-02-24
* src/ctests/inherit.c: Make the inherit test respect TESTS_QUIET
so that it does not print extra output during a run_tests.sh run
* src/ctests/overflow.c: Fix missing newline in the overflow
output.
Reported by Gary Mohr
* src/: papi_pfm_events.c, papi_pfm_events.h, perf_events.c: Move
the libpfm3 specific functions from perf_events.c into
papi_pfm_events.c
* src/perf_events.c: Separate the libpfm3-specific code from
_papi_pe_init_substrate() and _papi_pe_update_control_state()
into their own functions. This will allow eventual code sharing
and also make the libpfm4 merge easier.
* src/perf_events.c: Some minor cleanups I found after reviewing
the inherit merge. + Add missing "static inline" to the new
kernel-version codes + Remove duplicated test for Pentium 4
+ Fix a warning only seen if --with-debug is enabled
* src/: papi.c, papi.h, papi_internal.h, perf_events.c,
perf_events.h, ctests/Makefile, ctests/inherit.c,
ctests/test_utils.c: Merging Gary Mohr's re-implementation of
inherit into the code base. Thanks, Gary!
2011-02-23
* src/: any-null.h, freebsd.h, linux-bgp.h, linux-common.c,
linux-common.h, linux-context.h, linux-ia64.c, linux-ia64.h,
linux-lock.h, linux-memory.c, linux-ppc64.h, linux-timer.c,
papi_internal.h, papi_pfm_events.c, perf_events.c, perf_events.h,
perfctr-x86.h, perfctr.c, perfmon.h, solaris-niagara2.h,
solaris-ultra.h, solaris.h, x86_cache_info.c: Move some more
duplicated OS common code (in this case the locking code and the
context accessing code) out of the various substrate include
files and into a common location.
2011-02-22
* src/perf_events.c: Separate out the kernel-version dependent
checks and group them together near the beginning of the code.
This not only allows us to easily see which routines are
kernel-version dependent, but it makes it easier to disable the
checks one-by-one when debugging kernel-version related issues
like those found with the inherit patches.
2011-02-21
* src/papi_internal.c: Extend _papi_hwi_cleanup_eventset to free
memory and better cleanup after us.
2011-02-18
* src/papi.c: PAPI_assign_eventset_component changed; refuses to
reassign components.
2011-02-17
* src/: papi_events.csv, libpfm-3.y/include/perfmon/pfmlib.h,
libpfm-3.y/lib/amd64_events.h,
libpfm-3.y/lib/amd64_events_fam10h.h,
libpfm-3.y/lib/amd64_events_fam15h.h,
libpfm-3.y/lib/pfmlib_amd64.c,
libpfm-3.y/lib/pfmlib_amd64_priv.h: Add support for AMD Family
15h processors. Also adds suport for Family 10h RevE
Patches provided by Robert Richter
* src/utils/native_avail.c: Modify papi_native_avail to properly
handle event names with libpfm4-style "::" separators in them.
2011-02-15
* src/Makefile.inc: make install-doxyman will build/install the
doxygen version of the manpages.
Note that these pages are very rough right now, much work is
needed to get them to be a drop in replacement for the current
man pages. (mostly formatting related/use related issues, eg man
PAPI_start will not work yet; the content is there.)
* doc/Makefile: Add install target for doxygen generated man pages.
2011-02-11
* src/: perfctr-x86.c, perfctr.c: perfctr-2.6.42 introduced
PERFCTR_X86_INTEL_WSTMR PAPI added support for
PERFCTR_X86_INTEL_WSMR notice the missing T
Fix PAPI to use the proper define. This should fix Westmere
support on perfctr kernels.
2011-02-09
* src/: papi_protos.h, papi_vector.c, papi_vector.h,
papi_vector_redefine.h: Added function pointer destroy_eventset
to the PAPI vector table. Needed for the CUDA Component to
disable CUDA eventGroups, to destroy floating CUDA context, and
to free perfmon hardware on the GPU. (Note: the CUDA Component
cannot be released yet since we are still under NDA with NVIDIA.
Stay tuned.)
2011-02-07
* src/x86_cache_info.c: The cpuid leaf2 code was printing a message
to stderr if leaf4 was needed (only happens on Westmere
currently). Change this to be a MEMDBG() debug message instead.
2011-02-03
* src/: papi_events.csv, perfctr-x86.c: perfctr-x86 was reporting
"Core i7" instead of "Nehalem". i7 can mean Westmere or Sandy
Bridge too, so change the code to properly report Nehalem.
2011-01-27
* src/ctests/all_native_events.c:
Fix this ctest. It failed when the package was built with several
components because the eventset was reused and failed to add
events that were not from the first component.
In order to fix it, I recreate & destroy the eventset when the
current event does not belong to the previous component.
2011-01-26
* src/: configure, configure.in, linux-timer.c, perfmon.c: Fix Cray
CLE build.
* src/: configure, configure.in: Putting -Wall in cflags now
requires CC = gcc
* src/: aix.c, freebsd.c, linux-bgp.c, linux-common.c,
linux-memory.c, linux-memory.h, papi.c, papi_protos.h,
papi_vector.c, papi_vector.h, solaris-niagara2.c,
solaris-ultra.c, windows-common.c, windows-memory.c: Change the
paramaters passed to update_shlib_info() to match better with
those passed to get_system_info(). This only affects the
substrates, outside users of PAPI will not notice this change.
2011-01-25
* src/: configure, configure.in: Make sure that aix gets -g.
* src/: configure, configure.in: Give everyone else -g when
configuring with debug.
To wit, we pass gcc -g3 but neglected platforms where CC!=gcc.
* src/aix.c: First run at supporting power7. NOTE: this code is
only good for getting event listings eg papi_native_avail,
passing PM_GET_GROUPS causes our code to segfault later on, a
buffer overflow I'm still tracking down.
* src/perfctr-x86.c: Accidentally converted a function to _perfctr_
that should have stayed _linux_.
* src/: perfctr-x86.c, perfctr.c: Rename the various perfctr
functions to be _perfctr_ rather than _linux_. This way _linux_
is reserved for the common functions used by all.
* src/: linux-common.c, linux-memory.c, linux-timer.c,
perf_events.c, windows-common.c, windows-memory.c,
windows-timer.c: Split the WIN32 specific code out from the new
linux common code.
In most cases very little code was shared (it tended to be a big
#ifdef block) and it is confusing to have windows-specific code
in files named linux-*
2011-01-24
* src/linux-timer.c: Fix a compile error that only shows up on PPC.
* src/linux-timer.c: Fix compile warning if mmtimer is enabled.
* src/perfctr-x86.c: Missing comma in the perfctr code.
* src/: Makefile.inc, aix.c, configure, configure.in,
hwinfo_linux.c, linux-bgp.c, linux-common.c, linux-common.h,
linux-ia64.c, linux-timer.c, linux-timer.h, papi_vector.h,
perf_events.c, perfctr-x86.c, perfctr.c, perfmon.c,
solaris-niagara2.c, solaris-ultra.c: One last batch of
consolidation changes.
This one moves get_system_info and get_cpu_info into
linux-common.c, plus moves some other routines from perf_events.c
there that are shared by the future libpfm4 version.
Some non-linux substrates are touched here; these are just short
fixes to make sure the get_system_info() function pointed to by
the papi_vector has the same format on all substrates.
* src/: Makefile.inc, configure, configure.in, linux-memory.c,
linux-memory.h, perf_events.c, perfctr-x86.c, perfctr.c,
perfmon.c: Move the various Linux update_shlib_info() functions
into a common place.
* src/: Makefile.inc, linux-timer.c, linux-timer.h, perf_events.c,
perfctr-x86.c, perfctr.c, perfmon.c: Move the various
timer-related functions to linux-timer.c This gets rid of the
duplicated code spread throughout the substrates.
2011-01-21
* delete_before_release.sh, release_procedure.txt: Updated the
release docs with what I learned when making the 4.1.2.1 release.
* src/: configure, configure.in, freebsd-memory.c,
linux-ia64-memory.c, linux-memory.c, linux-memory.h,
linux-mx-memory.c, linux-ppc64-memory.c, perf_events.c,
perfctr-x86.c, perfmon-memory.c, perfmon.c: Currently there are
at least 3 identical copies of the linux memory detection code
spread throughout the PAPI source code.
This change puts them all in linux-memory.c, and then has all the
individual substrates use the common code.
