2019-02-17  Vince Weaver <vincent.weaver@maine.edu>

	* src/ctests/attach_cpu_sys_validate.c,
	  src/ctests/attach_cpu_validate.c: ctests: attach_cpu_*validate: fix
	  buffer overrun  embarassing bug, on systems with more than 16 cores
	  was running off the end of a buffer.  Oddly this did not fail on my
	  debian system with 32 cores.

2019-02-15  Anthony Castaldo <tonycastaldo@saturn.icl.utk.edu>

	* src/validation_tests/papi_tot_cyc.c: Added a 'priming' call of the
	  naive matrix multiply, before counting the cycles on the second
	  call. This is to overcome any first-time system overhead in the
	  procedure, like loading the program, so the cycles will better
	  match the 3rd and 4th calls. This corrects an error (and failure of
	  the test) in which the first call to the routine takes over 10%
	  more cycles to complete than the subsequent calls.
	* src/testlib/test_utils.c: Added new message to test_fail, so users
	  will not think a test failure means their PAPI install is unusable,
	  or that the failure should be reported to the PAPI development
	  team.
	* src/run_tests_exclude.txt: Added new memleak_check.c in
	  validation_tests; it is not a standalone test, but a utility to be
	  run by valgrind when checking for memory leaks.
	* release_procedure.txt: Release guidance improved with more details
	  on testing.

2019-02-11  Frank Winkler <frankbook@m016.zih.tu-dresden.de>

	* src/ctests/zero.c, src/validation_tests/cycles_validation.c: Fixed
	  warnings detected by clang. Replaced abs with llabs.
	* src/components/coretemp_freebsd/coretemp_freebsd.c: Fixed unused
	  warnings.

2019-02-08  Anthony Castaldo <tonycastaldo@saturn.icl.utk.edu>

	* src/components/perf_event/pe_libpfm4_events.c: revert change that
	  repaired a memory leak; it caused a problem with ARM systems, per
	  Vince Weaver.

2019-02-08  Vince Weaver <vincent.weaver@maine.edu>

	* src/linux-common.c: arm64: update the ARM family configuration to
	  work with newer Linux kernels.  As of Linux-3.19 the "CPU
	  architecture" field in /proc/cpuinfo changed from "AArch64" to "8".
	  Update the code so it properly falls back in this situation.
	  Reported-by: Al Grant <algrant109@gmail.com>

2019-02-08  Frank Winkler <frankbook@m016.zih.tu-dresden.de>

	* src/components/nvml/tests/Makefile: Fixed linking error.
	* src/components/nvml/linux-nvml.c: Fixed "this statement may fall
	  through" warning.
	* src/components/pcp/tests/testPCP.c: Fixed sprintf warnings by
	  replacing them with the safer method snprintf.
	* src/components/coretemp/linux-coretemp.c: Fixed warning: '%s'
	  directive output may be truncated.  Newer versions of gcc are more
	  strict with regards to return values of snprintf(), so check the
	  values.

2019-02-07  Anthony Castaldo <tonycastaldo@saturn.icl.utk.edu>

	* src/papi_internal.c: After PAPI_shutdown free(_papi_native_events);
	  must reset variables and counts to ensure next PAPI_library_init()
	  from same code will realloc() and rebuild the table.
	* src/libpfm4/Makefile, src/libpfm4/config.mk,
	  src/libpfm4/examples/Makefile, src/libpfm4/lib/pfmlib_perf_event.c,
	  src/libpfm4/perf_examples/Makefile: improve top makefile by
	  separating targets  This patch improves the Makefile structure by,
	  at the top level, separating the various targets: all, install-lib,
	  install-examples.  The patch keeps install_examples as a backward
	  compatible target. The patch also makes it possible to override
	  PREFIX from cmdline.

2019-02-06  Anthony Castaldo <tonycastaldo@saturn.icl.utk.edu>

	* src/validation_tests/Makefile.recipies,
	  src/validation_tests/memleak_check.c: memleak_check is a new simple
	  test file to help expose memory leaks in PAPI main and components.
	* src/papi_internal.c, src/papi_preset.c: Patches provided by Jiali
	  Li. Added cleanup code to prevent memory leaks.
	* src/libpfm4/lib/pfmlib_perf_event.c: Patches provided by Jiali Li.
	  Added cleanup code to prevent memory leaks.
	* src/components/stealtime/linux-stealtime.c: Patches provided by
	  Jiali Li. Added cleanup code to prevent memory leaks.
	* src/components/powercap/linux-powercap.c: Added cleanup code to
	  prevent some of the memory leaks. Dynamic-library related calls
	  leak, but we cannot prevent all of those leaks.
	* src/components/perf_event_uncore/perf_event_uncore.c: Patches
	  provided by Jiali Li. Added cleanup code to prevent memory leaks.
	* src/components/perf_event/pe_libpfm4_events.c: Patches provided by
	  Jiali Li. Added cleanup code to prevent memory leaks.
	* src/components/nvml/linux-nvml.c: Added cleanup code to prevent
	  some of the memory leaks. Dynamic-library related calls leak, but
	  we cannot prevent all of those leaks.
	* src/components/lustre/linux-lustre.c: Added cleanup code to prevent
	  memory leaks.
	* src/components/lmsensors/linux-lmsensors.c: Added cleanup code to
	  prevent some of the memory leaks. Dynamic-library related calls
	  leak, but we cannot prevent all of those leaks.
	* src/components/infiniband_umad/linux-infiniband_umad.c: Added
	  cleanup code to prevent some of the memory leaks. Dynamic-library
	  related calls leak, but we cannot prevent all of those leaks.

2019-02-06  Heike Jagode <jagode@icl.utk.edu>

	* src/components/cuda/tests/cudaTest_cupti_only.cu,
	  src/components/cuda/tests/likeComp_cupti_only.cu,
	  src/components/cuda/tests/simpleMultiGPU.cu,
	  src/components/cuda/tests/simpleMultiGPU.h,
	  src/components/cuda/tests/timer.h: Added more details to the
	  license statement for cuda tests.

2019-02-05  Anthony Castaldo <tonycastaldo@saturn.icl.utk.edu>

	* src/components/nvml/README: Expanded description of NVML component

	* doc/Doxyfile-common, src/Makefile.in, src/configure.in, src/papi.h:
	  Changing version number to 5.7.0.0.

2019-01-30  Anthony Castaldo <tonycastaldo@saturn.icl.utk.edu>

2019-01-30  William Cohen <wcohen@redhat.com>

	* src/run_tests.sh: Elimininating some of the SHELLCHECK_WARNINGS.
	  Removing unused variables. Correcting printf arguments.

2019-01-29  Konstantin Stefanov <cstef@parallel.ru>

	* src/components/nvml/linux-nvml.c: Change method for detecting
	  available NVML component events  Previously PAPI nvml component
	  used ROM version for detecting the type of the GPU and find which
	  events are supported. On some newer cards, e.g. Tesla Kepler and
	  Tesla Pascal, this gives wrong result. Those card support GPU and
	  memory utilization, for example, but it was not detected as Kepler
	  card may not have powerROM, and PAPI nvml considers it as an old
	  card.  So I changed the way the event availability is detected:
	  just try to obtain the info, and if it succeds, it is available.

2019-01-28  Anthony Castaldo <tonycastaldo@saturn.icl.utk.edu>

	* src/components/nvml/linux-nvml.c: Added (void)s to eliminate
	  warnings about unused variables.
	* src/components/cuda/linux-cuda.c: Corrected field-name typo in a
	  SUBDBG message that was not previously being compiled.
	* src/components/cuda/README, src/components/cuda/tests/LDLIB.src:
	  Changes about accessing to cupti libs and includes.
	* src/components/cuda/tests/simpleMultiGPU.cu,
	  src/components/nvml/tests/HelloWorld.cu: Corrected compile warnings
	  for deprecated routines or compiler complaints.

	* src/components/infiniband_umad/tests/infiniband_umad_list_events.c:
	  Code was missing the 'string.h' include necessary for use of

	* src/components/infiniband_umad/linux-infiniband_umad.c: Header file
	  changed; fixed prototypes for umad_get_ca() to use 'const char*'
	  instead of 'char*'.

	  Three patches to libpfm4. (1) Add Intel CascadeLake X core PMU
	  support. (2) Add get_num_events() support for Intel X86 (3) Check
	  PMU models when validating event codes.
	* src/components/cuda/tests/runSMG.sh: Example file to run
	  simpleMultiGPU.
	* src/components/cuda/tests/runCTCO.sh: Example file for running
	  cudaTest_cupti_only
	* src/components/cuda/tests/runBW.sh: Example script to run
	  nvlink_bandwidth on PEAK.
	* src/components/cuda/tests/runAll.sh: Example script to run
	  nvlink_all on PEAK.
	* src/components/cuda/tests/simpleMultiGPU.cu: This is a PAPI version
	  of an NVIDIA cupti-only sample program; it is a useful starting
	  point to test a variety of metrics or events, which are specified
	  in a simple internal table.
	* src/components/cuda/tests/likeComp_cupti_only.cu: This program
	  (likeComp = likeComponent) tested if the events in a metric could
	  be harvested and put into an event group, read and re-ordered to
	  provide data to cuptiMetricGetValue. They can; we did this before
	  rewriting the component to do all Metrics in this way.
	* src/components/cuda/tests/nvlink_bandwidth.cu: This is a tester for
	  just 4 NVLINK bandwidth metrics. It moves data from CPU (host) to
	  GPU, or GPU to GPU. Reporting of intermediate steps has been
	  increased, and we retrieve the number of Async engines dynamically
	  to optimize the number of streams used in the copies. It was
	  previously hard-coded.
	* src/components/cuda/tests/nvlink_all.cu: This utility will iterate
	  through all the available NVLINK metrics in the PAPI system, and
	  run a test program for each of them, and report the results to
	  stdout. The test program is memory movement, a command line
	  argument can test CPU(host) to GPU memory movement, or GPU to GPU
	  movement amongst available GPU devices.  The report consists of all
	  single events, followed by a list of all possible pairs of events
	  on one GPU, and multiple GPUS. This report notes which nvlink
	  events are incompatible pairs, and will also report if any metrics
	  in pairs produce significantly different measurements than when
	  they are read singly. All of this is done with PAPI.
	* src/components/cuda/tests/cudaTest_cupti_only.cu: This program will
	  test a single performance metric or event that is provided on the
	  command line, on one or more GPUs. Only cupti is used. The exercise
	  will include both extensive memory moves NOT executed by kernel,
	  and a kernel. Options allow the user to skip the kernel execution
	  if desired, and to optionally use cuInit() and reset the devices
	  before beginning the test. Reports of the steps in the process are
	  output to stdout. The purpose of this program is to show what a
	  cupti-only result looks like, in order to see if issues with an
	  event are in the PAPI implementation only, or also exist in a
	  cupti-only implementation.
	* src/components/cuda/tests/Makefile: Several targets were added for
	  new test and utility programs.
	* src/components/cuda/linux-cuda.c: Several changes were made to more
	  efficiently (and correctly) read and compute metrics, including the
	  newly added nvlink metrics. The previous method was not reading
	  groups properly; and though this did not cause an error, it could
	  result in zeros being read instead of actual values. The change is
	  to break down all metrics and events for a device into global event
	  list (without duplicates) and build a single event group set for
	  everything the user has added. We repeat this each time the user
	  adds an event; on the assumption that this overhead is less likely
	  to occur during a performance critical time than when the user
	  reads the event set. After reading all the resultant groups we then
	  re-order the events and values to compute each metric, then store
	  those values (and any other event values) back into the user-
	  provided order.  Outstanding Issues: We do not provide to the user
	  the cuda metric 'branch_efficiency', there is an issue with the
	  library code sometimes segfaulting while reading the events for
	  particular metric. The bug has been reported to nvidia as bug ID
	  2485834.

2019-01-10  Vince Weaver <vincent.weaver@maine.edu>

	* src/ctests/Makefile.recipies, src/ctests/attach_cpu_sys_validate.c:
	  ctests: add an attach_cpu_sys test  this test for the Linux bug
	  where you attach to a process with SYS granularity
	* src/components/perf_event/perf_event.c,
	  src/components/perf_event/perf_event_lib.h,
	  src/ctests/attach_cpu_validate.c: perf_event: fix granularity
	  setting for attached processes  the old code was setting the
	  granularity wrong when attaching to a CPU.
	* src/components/perf_event/perf_event.c: perf_event: properly fall
	  back to read() if rdpmc read attempt fails  The code wasn't
	  properly handling this.  We now fall back to read() if *any* rdpmc
	  call in an eventset fails. In theory it is possible to only fall
	  back in a per-event fashion but that would make the code a lot more
	  complex.
	* src/components/perf_event/perf_helpers.h: perf_event: internally
	  indicate we need fallback when rdpmc not available

	* src/ctests/branches.c: ctests/branches: remove code to set "sleep
	  time" which is no longer used
	* src/ctests/branches.c: ctests/branches: make the failure message
	  more verbose  to see what was going wrong.  the issue I was seeing
	  on Haswell was because there was some perf-related system load
	  happening on the same machine (the perf_fuzzer)
	* src/ctests/branches.c: ctests: branches, update code comments to
	  explain what test is doing  trying to figure out why sometimes
	  failing on Haswell system

	  standalone, and I rewrote the original nvlink_bandwidth.cu to make
	  it work properly with PAPI. I also added some testing scripts
	  needed to function on the PEAK supercomputer; where this code was
	  tested.

	* src/utils/papi_avail.c: Add a note to the output of "papi_avail -e

	* src/components/perf_event/perf_event.c: perf_event: remove debug
	  printf from libpfm4 error handling code  Steve Kaufmann reported
	  this triggered sometimes and was unnecessary
	* src/utils/papi_avail.c: papi_avail: fix the -e option to not print
	  spurious message  the "no events available" message should not be
	  printed if -e is being used

2018-09-27  Vince Weaver <vince@deater.net>

	* src/components/perf_event/perf_event.c: perf_event: avoid floating
	  point exception if running is 0  The perf_event interface isn't
	  supposed to return 0 for running, but it happens occasionally.  So
	  be sure not to divide by zero if this happens.  This makes the
	  rdpmc code match the generic perf code in this case.  This is in
	  response to bitbucket issue #52

2018-09-25  Heike Jagode <jagode@icl.utk.edu>

	* src/components/powercap/utils/powercap_plot.c: Temporary Fix: The
	  powercap component does not properly report energy values. At some
	  point in Nov 2017, the read() function was rewritten, which
	  resulted in numerous errors, such as: +++ the energy start values
	  are not subtracted from the read values. +++ wraparound is no
	  longer working properly. etc.  This commit serves as an immediate
	  workaround and adds a temporary fix to get the powercap_plot
	  utility working again. However, all this should and will be fixed
	  in the powercap component itself.

2018-09-21  Anthony Castaldo <tonycastaldo@saturn.icl.utk.edu>

	* src/components/cuda/tests/simpleMultiGPU.cu: Corrected a bug in the
	  CUPTI_ONLY version of simpleMultiGPU.cu. This manifested
	  specifically if the node has multiple GPUs and they are of
	  different models or types; in which case they can have differently
	  numbered PAPI events. We converted a scalar storing the eventID to
	  a vector with one eventID per GPU.

	* src/components/rapl/linux-rapl.c: rapl: add support for AMD Fam17h
	  (Zen) CPUs  AMD Fam17h chips have a new RAPL-like interface that
	  supports energy measurement using register layouts like Intel RAPL,
	  but at a different MSR number.  This has been tested on an EPYC
	  system and the package value seems to be plausible, but as reproted
	  by the LIKWID people the cores value seems a bit too low.

	  event descriptions for Intel Broadwell-EP uncore PMUs Now that we
	  have empty description detection, fix the ones detected in the
	  Intel Broadwell-EP uncore PMUs.   commit
	  05fc5910b78526d3cba3160713f467d9dcc0774b  detect empty event/umask

	* src/ctests/hl_rates.c, src/ctests/inherit.c, src/papi_hl.c: ctests:
	  change a few more test results from FAIL to SKIP when paranoid=3
	  there are some more that fail, but their failure errors make no
	  sense and are coming from deep within PAPI so I am not sure I can
	  easily fix things without making it worse.
	* src/ctests/attach2.c, src/ctests/attach3.c,
	  src/ctests/attach_cpu.c: ctests: attach tests, skip instead of fail
	  if not enough permissions
	* src/papi_internal.c: papi_internal: whitespace cleanup (no code
	  changes)
	* src/utils/papi_avail.c, src/utils/papi_native_avail.c: utils:
	  papi_avail/native_avail suggest papi_component_avail if no events
	  detected  If no events are detected, let the user know they should
	  use papi_component_avail to find out why.
	* src/papi_internal.c: papi_internal: comment the error generation
	  code  I'm not sure why we generate things this way, but it makes it
	  really confusing when adding a new error.
	* src/genpapifdef.c, src/papi.h, src/papi_common_strings.h,
	  src/papi_internal.c: add new PAPI_ECMP_DISABLED error  We can
	  return this error if an event is added but the component involved
	  is disabled.  If a user moves working code to a system where
	  perf_event_paranoid is set to 3 (all perf events disabled) they
	  will now get an error indicating the component is disabled rather
	  than an "event not found" error which was confusing.
	* src/ctests/zero.c: ctests: zero: print full error message if cannot
	  add

	* src/utils/papi_component_avail.c: utils: papi_component_avail: fix
	  the NAME field in the auto-generated manpage  Steve Kaufmann
	  noticed that the papi_component_avail NAME field for the auto-
	  generated manpage for some reason had info for papi_native_avail
	  instead.

	* src/configure, src/configure.in: Fixed compilation error that
	  occurs with deprecated option '-openmp' when using a more current
	  icc compiler.  Replaced with '-qopenmp'.  Tested with: icc/2016.0
	  icc/2017.4 icc/2018 icc/2018.1  Reported by Preeti Suman from
	  Intel.
