	* .../rocm/tests/multi_thread_monitoring.cpp: rocm: fix segmentation
	  fault in component test  On Frontier, the invocation of the exit()
	  call before pthread_merge() causes a segmentation fault. I remedy
	  this issue by only calling test_warn(), test_fail(), and
	  hip_test_fail() after the threads have been merged.  These changes
	  were tested using ROCm versions 6.1.3, 6.2.0, 6.2.4, 6.3.1, and
	  6.4.0 with the AMD MI250X architecture on the Frontier
	  supercomputer.

	* src/components/intel_gpu/README.md: intel_gpu: update environment
	  variable name  On a system containing the Intel Arc A770 device, I
	  am met with the following warning:  ZET_ENABLE_API_TRACING_EXP is
	  deprecated. Use ZE_ENABLE_TRACING_LAYER instead.  The current
	  README states to set ZET_ENABLE_API_TRACING_EXP; however,
	  ZE_ENABLE_TRACING_LAYER is the correct variable to set. Setting
	  ZE_ENABLE_TRACING_LAYER prevents the above warning.

	  force init per existing policy  PR #284 introduced code that always
	  forced the initialization of all components. However, this defeats
	  the purpose of having PAPI_EDELAY_INIT.  The changes in this pull
	  request only force initialization of components when necessary.
	  These changes have been tested on systems containing: - NVIDIA
	  Hopper architecture - AMD Zen3 CPU and AMD MI250X GPU architectures
	  (Frontier).

	  c5587f9931123be6fcb6f8133497d93cab36bdcd  Hotfix ARM CPU detection
	  due to arch mismatch  This is a hotfix to avoid failure of ARM CPU
	  detection with the new detection code introduce by commit
	  15c4cd9f1f4a ("Add ARM hybrid detection").  For some processors,
	  the architecture revision expected by libpfm4 does not match the
	  revision exported by the Linux kernel via cpuinfo. For instance,
	  the Neoverse V2 is a V9 processor, yet cpuinfo reports arch: 8. A
	  few other ARM processors may exhibit the same error.  The hotfix
	  simply skips checking the arch revision for now.   commit
	  b2888ea7995d781d1c59d9c8714487b863774912  Cope with empty
	  /proc/cpuinfo file  When running inside e.g. lxc containers,
	  /proc/cpuinfo may be empty, in which case pfmlib_getl() never
	  allocates a buffer, and the trailing b[i] = '\0' thus becomes
	  bogus.   commit f09c366b45fba75f1143cb14ec8f22ad96c4c1b1 Merge:
	  e887d24 8ca3087  Merge /u/mousezhang/perfmon2/ branch master into

	  requests/32/  commit e887d24a6c4b97b8087e5a284c79f63adaab4fc0  Add
	  sysfs PMU caching on initialization  In order to accommodate the
	  growing number of PMUs active and to handle hybrid processors
	  better, this patch adds sysfs PMU perf_events information caching
	  to avoid going back to sysfs for each encoded event. The caching
	  stores the name of PMU, e.g., armv8_pmu3, and the perf_events type
	  which is then use to build the perf_events encoding.   commit
	  ff3291fe3f6d2c280ed2e33c42842e5dc08f38df  Remove references to
	  /sys/devices to remain compatible with upstream  The PMUs will not
	  appear in /sys/devices for much longer. The proper way to access
	  PMU directories is via: /sys/bus/event_source/devices/  Where each
	  PMU has a symlink.  It should be noted that this alternate
	  directory is not new. It has been there all along. Therefore it is
	  okay to remove all references to /sys/devices.   commit
	  a41f8eeedf2c81232e5fa9129928edf9215bf3fc  Add ARM hybrid encoding
	  support for perf_events  This patch adds the new logic to handle
	  encoding of the PMU type for the Linux perf_events interface.
	  Hybrids are a challenge in that it is not possible to simply use
	  PERF_TYPE_RAW because that does not disambiguate which of the core
	  PMU models to attach the events to. Instead, the PMU type must be
	  collected from the Linux sysfs interface. But for that to happen
	  the library needs to know the PMU instance name assigned by
	  perf_events for each PMU model detected. On ARM, this is not
	  straightforward.  The patch extends the meaning the the
	  pmu->perf_name string to include a comma separated list of names
	  instead of just one. The library then tries each name until there
	  is a match in /sys/bus/event_source/devices/. This accommodates
	  situations where the same PMU model is used in a homogeneous vs.
	  hybrid config.   commit 15c4cd9f1f4a382ef6753a05a5d4d6c27bd449c5
	  Add ARM hybrid detection  This patch rewrites the ARM core PMU
	  detection logic to handle the case of hybrid processors. On ARM,
	  there can be many different cores in the same SoC. Each potentially
	  shows up with a different implementer, part, variant. That means
	  just looking at the first entry in cpuinfo on Linux is not enough
	  to activate all supported event tables.  The new code parses the
	  entire cpuinfo once and detects each unique core identifiers. Then,
	  for each core PMU table, the detection code checks against that
	  pre-built list of detected core models. That way up to N (currently
	  8) different core models can be detected.  This new detection code
	  is provided for Linux. For other operating systems, new code must
	  be added to get the implementer, part, variant codes for all cores
	  in the system.  Thanks to Vince Weaver for providing the test cases
	  to exercise this new code.   Testing: AMD Zen5 Update (Tested on a
	  AMD Ryzen 9 9950X 16-Core Processor): - papi_avail - runs
	  successfully and matches master branch - papi_component_avail -
	  runs successfully and matches master branch - papi_native_avail -
	  runs successfully and matches master branch - papi_command_line -
	  runs successfully  I verified that with papi_native_avail we see
	  the swapped umasks for L2_PREFETCH_MISS_L3 and
	  L2_FILL_RESPONSE_SRC. Using the swapped umasks with
	  papi_command_line work as expected.  ARM Updates (Tested on ARM
	  Cortex A57, ARM Cortex A72, and ARM Neoverse V2): - papi_avail -
	  runs successfully on all three models and matches master branch -
	  papi_component_avail - runs successfully on all three models and
	  matches master branch - papi_native_avail - runs successfully on
	  all three models and matches master branch - papi_command_line -
	  runs successfully on all three models  Note that for the ARM
	  updates, this includes Vince's patch to resolve Issue #364.

	  topdown: Use librseq to protect rdpmc on het cpus  On Intel's
	  heterogeneous multicore processors such as Raptor Lake, the
	  PERF_METRICS MSR is only available on the performance cores
	  (p-cores). If the rdpmc instruction is executed attempting to
	  access the MSR while the process is on an efficient core (e-core),
	  a segmentation fault occurs.  Previously, the topdown component has
	  used a simple check before every execution of the rdpmc instruction
	  to ensure the core the program is bound to is a p-core. However,
	  this can fail if the program is moved to another core between the
	  check and the execution of rdpmc. While rare, a worst-case scenario
	  test that repeatedly moves a program which is using the topdown
	  component from p-core to e-core at a random time saw 338
	  segmentation faults out of 1 million affinity switches (a 0.0338%
	  error rate). This is a non-zero number of segmentation faults, and
	  we can do better.  Use librseq to protect the rdpmc instruction
	  with a restartable sequence (rseq). When the process is preempted
	  by an affinity change, the sequence immediately aborts and can be
	  restarted. By keeping the check that the process is on a p-core and
	  the rdpmc instruction itself within the critical section of the
	  rseq, it is guaranteed that the rdpmc instruction will never be
	  executed on an invalid core. The same test described in the
	  previous paragraph sees 0 segmentation faults.

	* src/components/topdown/topdown.c: topdown: simplified metrics
	  calculation  Previously, the topdown component calculated metrics
	  by taking the difference of the metrics before and the metrics
	  after the calculated code block using Equation 1:  M% = (Mb*Sb/255
	  - Ma*Sa/255) / (Sb - Sa) * 100                   (1)  where Mx are
	  the raw bytes of the metric before and after the calipered code
	  block and Sx are the slots. However, if Sa = 0 this simplifies to
	  M% = Mb/255 * 100
	  (2)  Therefore it is sufficient to simply reset the PERF_METRICS
	  MSR and SLOTS during PAPI_start() and then use Equation 2 in
	  PAPI_stop, reducing the number of dangerous rdpmc calls, reducing
	  overhead, and simplifying the code.

	* src/components/topdown/topdown.c: topdown: relocated core type
	  checks  To prevent programs using the topdown component on
	  heterogeneous processors that only supply the PERF_METRICS MSR on
	  some of their cores from segfaulting due to trying to read the MSR
	  after being moved to an unsupported core type, the topdown
	  component periodically checks it is on a supported core and exits
	  if not.  Previously, this check occured at the start of PAPI_start
	  and PAPI_stop. After writing a script that starts a program being
	  calipered with the topdown component and moves it to an unsupported
	  core after a random amount of time, for N=100,000 tests the
	  heterogeneous checks failed to prevent a segmentation fault 0.08%
	  of the time. This patch moves the heterogeneous checks to occur
	  only directly before the rdpmc calls, resulting in cleaner code and
	  a reduced segfault prevention failure rate of 0.064%.  While it is
	  frustrating that the failure rate is non-zero, since there appears
	  to be no way to tell a process to ignore changes to its affinity, I
	  believe there to be no perfect solution at this time.

	  component on ARM systems to fail. Therefore, remove the include and
	  add a manual definition for _rdpmc() taken from the perf_event
	  component.

	  topdown: Prevent segfault on heterogeneous CPUs  All of Intel's

	  it for their performance (p-core) cores. This means that if a
	  program that is being measured using the topdown component in PAPI
	  happens to be rescheduled to a e-core during its runtime, PAPI will
	  segfault.  To fix this, add a check in _topdown_start() and

	  process has changed to an unsupported core type.

	* src/components/topdown/topdown.c: topdown: add arch support based
	  on perfmon-intel  While the offical Software Developer Manual only
	  lists the availability of the PERF_METRICS MSR for three
	  architectures, we can use the 'perfmon' repository maintained by
	  Intel to discover what architectures support the MSR (repo here:
	  https://github.com/intel/perfmon).  Architectures that the
	  repository demonstrates support the events
	  'PERF_METRICS.BACKEND_BOUND', 'PERF_METRICS.FRONTEND_BOUND', etc.
	  must support the topdown level 1 metrics of the PERF_METRICS MSR.
	  Similarly, the presence of the events 'PERF_METRICS.FETCH_LATENCY',
	  'PERF_METRICS.MEMORY_BOUND', etc. demonstrates support for topdown
	  L2 metrics in the PERF_METRICS MSR. By cross-referencing the
	  architecture names in the perfmon repository with their
	  DisplayFamily/DisplayModel values in Table 2-1 of volume 4 of the
	  IA32 SDM, we can add support for the following architectures:  -
	  Rocket Lake - Ice Lake (icl & icx) - Tiger Lake - Sapphire Rapids -
	  Meteor Lake (redwood cove p-core only) - Alder Lake (golden cove
	  p-core only) - Granite Rapids - Everald Rapids  None of these
	  additional architectures have been tested with the topdown
	  component yet. While Arrow Lake is shown to support L1 & L2 metrics
	  in the prefmon repository, its FamilyModel is not yet available in
	  the IA32 SDM so it has not been added.
