2011-05-10 * 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: 184.108.40.206 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 <email@example.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 <firstname.lastname@example.org> * src/papi_pfm_events.c: papi: Fix crash in error handler for pfm_get_event_code_counter() Signed-off-by: Robert Richter <email@example.com> * src/utils/native_avail.c: papi: Fix error check in native_avail.c Signed-off-by: Robert Richter <firstname.lastname@example.org> 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 220.127.116.11 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.
