  * 6b62d586 man/man1/papi_avail.1 man/man1/papi_clockres.1
  man/man1/papi_command_line.1...: Update the manpages for a pending 5.2
  release.  New pages for PAPI[F]_epc and papi_version.

  * 1ae08835 src/linux-common.c: try to properly detect number of sockets  Use
  totalcpus rather than ncpu in the calculation.  This change fixes things on a
  Sandybridge-EP machine.  We should maybe find a more robust way to detect
  this.

  * 79c37fbf .../perf_event_uncore/tests/perf_event_uncore.c
  .../tests/perf_event_uncore_multiple.c: perf_event_uncore: have tests skip if
  component disabled rather than fail

  * 638ccf6b .../perf_event_uncore/perf_event_uncore.c: perf_event_uncore:
  change order of uncore detection logic  This way it will report an error of
  "no uncore found" before it reports "not enough permissions".  That way a
  user won't waste time getting permissions only to find out they didn't have
  an uncore anyway.

  * 30582773 src/components/perf_event/pe_libpfm4_events.c: perf_event: fix
  papi_native_avail output  A recent change of mine that added stricter error
  checking for libpfm4 event lookup broke event enumeration on perf_event,
  specifically papi_native_avail output.  libpfm4 will return an error on some
  events if no UMASK or improper UMASK is supplied, but papi_native_avail
  always wants to print the root event and umasks separately.  this temporary
  fix just ignores libpfm4 umask errors; we might in the future want to
  properly indicate which events are only valid when certain umasks are
  present.

  .../perf_event_uncore/perf_event_uncore.c
  .../perf_event_uncore/peu_libpfm4_events.c: perf_event libpfm4 events --
  correctly handle invalid events  It was possible for event names to be
  obtained from libpfm4 during enumeration that were not valid events.  This
  usually happens with uncore events, where the uncore is listed as available
  based on cpuid but when libpfm4 tries to get the uncore type from the kernel
  finds out it is unsupported.  This change makes this properly fail, instead
  of just returning "0" for all the event paramaters (which is a valid event on
  x86).  Also make this change in the regular perf_event component, even though
  it is less likely to happen in practice.

  * 4720890a .../perf_event_uncore/perf_event_uncore.c: perf_event_uncore:
  remove check_permissions() test  It was trying to see if an EventSet was
  runnable by using the current permissions and adding the PERF_HW_INSTRUCTIONS
  event. That doesn't really make sense on uncore.  The perf_event component
  uses this test to try to give errors early, at set_opt() time rather than at
  the first run time, although in practice now we can probably make intelligent
  guesses based on the current permission levels.

  * 113d35f7 .../perf_event_uncore/perf_event_uncore.c: perf_event_uncore:
  remove unused kernel workarounds  uncore only works on Linux 3.6 or newer so

  backported the uncore support to kernels that old, hopefully they've also
  backported all the other bugfixes too.

  * 4cb76a9b src/components/cuda/linux-cuda.c: Trial fix for the cuda component
  static libc linking issue.  Weak link against _dl_non_dynamic_init, this
  appears in my limited testing to be in gnu libc.a and not in the so.  For
  background, it was reported by Steve Kaufmann that statically linking tools
  with a PAPI library configured with the CUDA component segfaulted. It appears
  that calling any of the dynamic linker functions from a static executable is
  asking for pain.  See Trac bug 182

  * c0c4caf4 src/linux-memory.c src/papi_events.csv: Add initial support for
  IBM POWER8 processor  Add initial support for IBM POWER8 processor  The IBM
  POWER8 processor (to be publicly announced at some future date) has some
  preliminary support in libpfm with a subset of native events.  These
  POWER8-related libpfm changes were pulled into PAPI on July 3, so further
  updates in PAPI were required to support this new processor.  This patch adds
  that required support.  NOTE: Due to the fact that only a subset of native
  events have been publicised at this point (and pushed into libpfm), not all
  of the usual PAPI preset events have corresponding native events. The rest of
  the POWER8 native events will be pushed upstream once they are verified, and
  then we can flesh out the PAPI preset events.  With this initial POWER8
  support patch, 5 of the ctests and ftests fail, compared to 3 when PAPI is
  run on a POWER7. At least one of the failing testcases is due to testing
  being done on an early POWER8 processor with some known hardware problems. We
  presume the number of failing tests will decrease once we have GA-level
  hardware to test on.

  * f4ec143e src/configure.in: Correct versioning of libpapi.so  The configure
  for linux always set the soname to libpapi.so.  This causes problems when
  /sbin/ldconfig tries to update the library information on linux.  The shared
  library is installed as /lib{64}/libpapi.so.$VERSION, but the shared library
  has the soname of libpapi.so.  ldconfig makes a symbolic link from
  /lib/libpapi.so to the actual versioned shared library,
  /lib/{64}/libpapi.so$VERSION. The configure should get the soname correct to
  avoid creating this symbolic link.  This patch only addresses the issues for
  some of the possible platforms and similar patches may be needed for other
  platforms.

  * 92356bbd src/papi.c src/threads.c src/threads.h: Attempt to fix a memory

  _papi_hwi_shutdown_global_threads() -> foreach(threadinfo we allocated):
  _papi_hwi_shutdown_thread() PAPI_library_init()  _papi_hwi_shutdown_thread
  checks who allocated a ThreadInfo entry in the global list, and will only
  free it if our thread did the allocation.  When threading is not initialized,
  we fall back to getpid(), now in the child process, the one ThreadInfo item
  on the list was allocated by our parent, so at shutdown time we don't free
  this, and thus leak it.  Solution is to add a parameter to
  _hwi_shutdown_thread to force shutdown even if we didn't allocate it. At

  Reported by Steve Kaufmann -------------------------- I noticed while

  prefix is not being taken into account, so the base event name is interpreted
  as a unit mask and is prepend with a : before each legitimate unit mask
  associated with the event. I think this is just now happening because mine is
  the first component that has unit masks. I have include a fix below. The
  output of the unit masks by papi_native_avail now appears correctly for my
  component.  Thanks, Steve

  * 2b1433d8 src/ctests/all_native_events.c src/ctests/get_event_component.c:
  ctests: Skip calling into disabled components.  This patch fixes a problem
  that was causing two test cases to abort when they were run on a system which
  has disabled components.  Code was added to check if the component is
  disabled and just go to the next component in the list when the check is
  true.  This prevents calls to code in components which may abort because the
  component was unable to initialize itself correctly.  Thanks to Gary Mohr and
  Chuck LaCasse from Bull for reporting.

  * 1872453c src/testlib/do_loops.c: testlib: don't change the iter count  The
  first argument to do_misses is an iteration count, for some reason the code
  was dividing this in half before doing work. Most places that call do_misses
  call it as do_misses ( 1, ...)  void do_misses( int n, int bytes ) { {...} n
  = n / 2; for ( j = 0; j < n; j++ ) {  1/2 == 0; so our do_misses call was
  usually not.  Thanks Nils Smeds for reporting.

  * c113e5b6 src/components/infiniband/Makefile.infiniband.in
  src/components/infiniband/Rules.infiniband
  src/components/infiniband/configure...: Infiniband component: switch over to
  weak linking  Thnaks to Gary Mohr for the patch.
  ---------------------------------- The infiniband component needs include
  files and libraries from both the infiniband ibmad and ibumad packages.  When
  these packages are installed on a system, both packages normally install
  their files in the same place (includes in /usr/include/infiniband and
  libraries in /usr/lib64).  The current component configure script allows you
  to provide a single include path and a single library path which gets used to
  access files from both packages.  If these two packages have different
  install prefixes (or you are trying to build from install images of each
  package which are not located under the same directory) then the configure
  script fails because it can not find all the files it needs.  These changes
  modify the configure script to replace the include and library dir's with an
  ibmad_dir and ibumad_dir and then uses the correct packages directory when
  looking for includes and libraries from that package.  This makes it work
  like the cuda and nvml components with respect to configuring how to find
  files from a package the component depends on.  There are also changes in
  this patch file to remove an unneeded variable in the dlopen code to resolve
  some defects reported by coverity.

  but never used them. Thanks to Gary Mohr for submitting this patch.

  * 99b5b685 src/components/coretemp/tests/coretemp_basic.c: coretemp_basic:
  update test to properly enumerate events  The code was old and was searching
  the entire native event list for ones that started with "hwmon".  This
  updates the test to first find the coretemp component, then enumerate all
  events contained within.

  * b5c0795b src/components/rapl/tests/rapl_overflow.c: rapl component: address
  potential looping issue in test.  A rapl component test has a do/while which
  only exited when PAPI_add_named_event returned 0 ( and only 0; the PAPI_E*
  error codes would not terminate a while( retval ) loop), this felt fragile,
  minimal checks are now inplace.

  * 4e9484a5 src/components/rapl/tests/rapl_overflow.c: rapl components:
  coverity fixes  Reported/patched by Gary Mohr -----------------------------
  The rapl component also has 1 defect in a test case.  The complaint is that
  there is code that can never be executed.  But this one is not as clear, it
  says that you can not exit the do/while loop that preceeds a test of retval
  until retval=0 which means the test can never be true.  The patch I am
  providing is to again remove the if test and its contents.  But I am
  concerned that the do/while loop preceeding the test could result in a hard
  loop that would hang the test case forever.  It seems to me like something
  should also be done to insure the loop will exit at some point.  Here is a
  patch that provides at least part of the fix: -----------------------------

  * 0a533810 src/components/net/tests/net_values_by_name.c: net components:

  The net component has one defect in one of the test cases.  The complaint is
  that there is code that can never be executed.  There is a test to see if
  event_count == 0 which can never be true at that place in the code.  So I
  removed the if statement and its contents.  Here is the patch:

  * bda86616 .../perf_event_uncore/perf_event_uncore.c
  src/ctests/get_event_component.c src/papi_internal.c: Some more ctest fixes
  involving disabled components.  We enforce disabled components sometime in
  the PAPI routines and sometimes in the components themselves.  A bit
  confusing.  It is tough with perf_event and perf_event_uncore because we
  share libpfm4 by both, so the naming library for perf_event_uncore will be
  active even if the component is disabled, which can cause some confusing
  results if your test code ignores PAPI_ENOCMP error messages and accesses a
  disabled component anyway.  This at least fixes our test cases, we might have
  to revisit this later.

  * b596621e doc/Doxyfile-common papi.spec src/Makefile.in...: Bump version

  CPUCOMPONENT_OBJ This allows having setups with no CPUCOMPONENT set
  (perf_event used as a component) while keeping backward compatible with
  non-component CPU components.  This has been tested on perf_event and
  perfctr.  It might break other architectures, so test if you can.

  * 69e29526 src/configure src/configure.in: configure: have --with-components

  Now we can have an uncore-only component.

  * 6554f3f0 src/papi_libpfm4_events.c: papi_libpfm4_events.c: only enable

  want to load the presets if it is component 0.

  * 6a4a4594 src/papi.c: PAPI_get_component_index() was matching names

  the same component.

  * 1b94e157 src/papi_hl.c: papi_hl.c : fix IPC calculation  I broke it a while

2013-05-15  

  * 7ddc05ff src/cpus.c src/cpus.h: cpus.c: Add reference count to cpu
  structure  It is possible to have multiple eventsets all attached to the same
  CPU, as long as only one eventset is running at a time.  At EventSet cleanup,
  PAPI would free the CpuInfo_t structure even if other EventSets were still
  using it.  This patch adds a reference count to the structure and only frees
  it after the last user is cleaned up.  I also fixed a few locking bugs,
  hopefully I didn't introduce any new ones.

  * 6a61f9a2 src/cpus.c: more cleanup of the cpus.c file  mostly formatting and
  added comments.

  * 38397aa3 src/components/cuda/configure src/components/cuda/configure.in
  src/components/cuda/linux-cuda.c...: Cuda component: Update library search
  path  From Gary Mohr: It turns out that with the changes I gave you the path
  to the libcuda.so library is still hard coded to /usr/lib64.  This assumes
  that the NVIDIA-Linux package is installed on the system where the build is
  being done.  In Bull's case (and probably other users also) this is not
  always the case.  To add the flexibility we need, I have added a new
  configure argument to the cuda configure script.  The new argument is
  "--with-cudrv_dir" and it allows the user to specify where the cuda driver
  package (ie: NVIDIA-Linux) to be used for the build can be found.  This new
  argument is optional and if not provided a value of "/usr" will be used. This
  allows existing configure calls to continue to work like before.

  * c824471b src/ctests/Makefile src/ctests/perf_event_system_wide.c
  src/ctests/perf_event_uncore.c...: Update the perf_event specific tests.

2013-05-08  

  * e0204914 src/configure src/configure.in: Force the use of pthread_mutexes
  on ARM  This lets the system libraries worry about the best way to define
  mutexes, rather than trying to hand-code in assembly around all of the
  various issues there are with atomic instructions in the ARM architecture. 
  It might make sense to enable this for *all* Linux architectures, but for now
  just do it for ARM.

  * f21b1b27 src/linux-lock.h: Commit 59d3d7584b2925bd05b4b5d0f4fe89666eb8494a
  removed the definition of mb().  mb() was defined as rmb().  This just
  corrects it back.   (Note from VMW -- this fixes some things, but ARM still
  won't build on a Cortex A9 pandaboard due to the use of the "swp"
  instruction. Proper fix is probably to enforce posix-mutexes on ARM)

  Ralph:  Seeing your latest change reminded me: Anytime there is a value
  issued in hex or octal the "%#" conversion should be used so the value is
  always preceded with a "0" for octal or a "0x" for hex. Otherwise when a
  value is printed one can not tell the base it is in (one shouldn't have to
  rely on internal knowledge of the code or the context to tell). For variables
  that are pointers the "%p" conversion can be used (this will always use an
  hex syntax).  It would be nice to apply this to all PAPI print statements in
  their entirety.

  * 8dddd587 src/papi_hl.c: papi_hl: Use PAPI_get_virt_usec() for process time 
  The code was using cycles / MHz which is not guaranteed to work on modern

  which hopefully isn't necessary for any machine PAPI currently supports. 
  Instead use PAPI_get_virt_usec() which should give the right value.

  * 97a4a5ea src/components/cuda/Rules.cuda src/components/cuda/linux-cuda.c
  src/components/cuda/tests/Makefile: Cuda component enhancement. 
  ---------------- From Gary's submission--------------------------------- The
  current packaging of the cuda component in PAPI has a fairly unfriendly side
  effect.  When PAPI is built with the cuda component, then that copy of PAPI
  can only be used on systems where the cuda libraries are installed. If it is
  installed on a system without these libraries then all PAPI services fail
  because they have references to libraries which can not be found.  Even
  papi_avail which you would think has nothing to do with cuda reports the
  error.  This issue significantly complicates the delivery and install of the
  PAPI package on large clusters where some of the nodes have NVIDIA GPU's (and
  the cuda libraries to talk to them) and other nodes do not have GPU's (and
  therefore no software to access them).  I have been working with the help of
  Phil Mucci to eliminate this dependency so that a copy of PAPI built with a
  cuda component could be installed on all nodes in the cluster and if the node
  had NVIDIA GPU's (and libraries available) then the cuda component would get
  enabled and could be used.  If the node did not have the hardware or the
  access libraries were not available, then the cuda component would just
  disable itself at component initialization so it could not be used (but all
  other PAPI services would still work).  Phil has provided some gentle
  prodding and lots of valuable suggestions to assist this effort.  I now think
  that I have a working version of this capability and am ready to share it
  with the community.
  -----------------------------------------------------------------------  Many
  thanks to Gary Mohr and Phil Mucci for this much needed functionality.

   I was running the Cuda test case on a system which did not actually have any
  NVIDIA GPU's installed on it (but the cuda software was installed and papi
  was built with the cuda component).  I modified the test case to put an real
  cuda event in the source (as suggested in the source).  When I run the test
  case the cuda component gets disabled in PAPI_library_init (because
  detectDevice function can not find any GPU's) which is the correct behavior.
  The test case then calls PAPI_event_name_to_code which failed because the
  cuda component was disabled.  The test case then created an event set and
  called PAPI_add_events with an empty list of events to be added.  This led to
  a segfault somewhere inside libpfm4.  The attached patch makes some minor
  changes to protect against this problem.  I noticed this test case does not
  use the PAPI test framework utilities (test_xxxx functions) so I did not
  modify the test to use them.

  * 457bfd74 src/components/cuda/linux-cuda.c: When creating two event sets -
  one for the CUDA and one for the CPU component  - the order of event set
  creation appears crucial. When the CPU event set has been created before the
  CUDA event set then PAPI_start() for the CUDA event set works fine. However,
  if the CUDA event set has been created before the CPU event set, then
  PAPI_start(CUDA_event_set) forces the CUDA control state to be updated one
  more time, even if the CUDA event set has not been modified. The CUDA control
  state function did not properly handle this case and hence cause PAPI_start()
  to fail. This has been fixed.

  * 6a40c8ba src/run_tests.sh: run_tests.sh: File mode changes.  run_tests.sh
  is now expected to run from the install location in addition to src. The
  script tried to remove execute from *.[c|h], now it just excludes *.[c|h]
  from the find commands.

  * 2ba9f473 src/perfctr-x86.c: perfctr: don't read in event table multiple
  times  papi_libpfm3_events.c now reads in the predefined events, we don't
  also need to do this in perfctr setup_x86_presets()

  * 326401b1 src/perfctr.c: Fix segfault in perfctr.c  The preset lookup uses
  the cidx index, but in perfctr.c we weren't passing a cidx value (it was
  being left off).  The old perfctr code plays games with defining extern
  functions so the compiler wasn't giving us a warning.

  * 50130c6f src/components/bgpm/L2unit/linux-L2unit.c src/linux-bgq.c: If a
  counter is not set to overflow (threshold==0; happens when PAPI_shutdown is
  called) then we do not want to rebuild the BGPM event set, even if the event
  set has been used previously and hence "applied or attached". Usually if an
  event set has been applied or attached prior to setting overflow, the BGPM
  event set needs to be deleted and recreated (which implies malloc() from
  within BGPM). Not so, though, if threshold is 0 which is the case when
  PAPI_shutdown is called.  Note, this only applies to Punit and L2unit, not
  IOunit since an IOunit event set in not applied or attached.

  Linux-SPARC  I dug out an old SPARC machine and fixed the PAPI build on it.

  * 2c7f102c src/perf_events.c: More comprehensive sys_perf_open to PAPI error
  mappings  This tries to cover more of the errors returned by sys_perf_open
  and map them to better results.  EINVAL is a problem because it can mean
  Conflict as well as Event not found and many other things, so it's unclear
  what to do with it.

  * 299070ef src/perf_events.c src/sys_perf_event_open.c: Return proper error
  codes for sys_perf_event_open  For some reason on x86 and x86_64 we were
  trying to set errno manually and thus over-writing the proper errno value,
  causing all errors to look like PAPI_EPERM  This removes that code, as well
  as adds code to report ENOENT as PAPI_ENOEVENT.  With this change, on IVY
  this happens which looks more correct.  ./utils/papi_command_line
  perf::L1-ICACHE-PREFETCHES Failed adding: perf::L1-ICACHE-PREFETCHES because:
  Event does not exist command_line.c                       PASSED

  * baa557ca src/papi_libpfm4_events.c src/papi_user_events.c: Coverity fixes: 
  Coverity pointed out that there was a case where load_user_eent_table() could
  leak memory.  The change in the location of the papi_free(foo) ensures that
  the allocated memory is freed.  Coverity pointed out one path through the
  code in _papi_libpfm4_ntv_code_to_descr() that did not free up memory
  allocated in the function.  Added a free on the path in free up that memory. 
  Thanks Will Cohen.

  * 395b7bc7 src/Makefile.inc src/components/README
  src/components/appio/tests/Makefile...: Add component tests' to the
  install-[all|tests] target.  Thanks to Gary Mohr. ------------------- This
  makes a fairly small change to src/Makefile.inc to add logic that adds a new
  install-comp_tests target which calls the install target for each component
  being built. This new target is listed as a dependency on the install-tests
  target so it will happen when the 'install-all', 'install-tests', or
  'install-comp_tests' targets are used. A note about this change, I am not
  real familiar with the auto make and auto conf tools. This change was enough
  to make it work for me but if there is another file that should also be
  changed for this modification, please help me out here.  The patch also adds
  install targets to the Makefiles for all of the components which have 'tests'
  directories and updates the README file which talks about how to create
  component tests.  Another note, I only compile with a couple of components
  (ours, rapl, and example) so if I fat fingered something in one of the other
  components Makefiles I would not have noticed. Please keep me honest and make
  sure you compile with them all enabled.  Thanks for adding this capability
  for us. Gary ---------------------------  Makefile.inc: Add run_tests and
  friends to install-tests target.  Component test Makefiles' get their install
  location to mirror what runtests expects.
