ad10c9201d perf vendor events intel: Refresh alderlake events 
Update the alderlake events from 1.16 to 1.18. Generation was done
using https://github.com/intel/perfmon.

Notable changes are new events and event descriptions, TMA metrics are
updated to version 4.5, TMA info metrics are renamed from their node
name to be lower case and prefixed by tma_info_, MetricThreshold
expressions are added, smi_cost and transaction metric groups are
added replicating existing hard coded metrics in stat-shadow.

900536349d perf pmu-events: Make the metric_constraint an enum 
Rename metric_constraint to event_grouping to better explain what the
variable is used for. Switch to use an enum for encoding instead of a
string. Rather than just no constraint/grouping information or
"NO_NMI_WATCHDOG", have 4 enum values. The values encode whether to
group or not, and two cases where the behavior is dependent on either
the NMI watchdog being enabled or SMT being enabled.

207f7df727 perf expr: Make the online topology accessible globally 
Knowing the topology of online CPUs is useful for more than just expr
literals. Move to a global function that caches the value. An
additional upside is that this may also avoid computing the CPU

180a501346 perf metrics: Improve variable names 
has_constraint implies the NMI_WATCHDOG_CONSTRAINT and if the
constraint is detected it causes events not to be grouped. Most of the
code cares about whether events are grouped or not, so rename
has_constraint to group_events.

Also remove group from metricgroup___watchdog_constraint_hint as the
warning is specific to a metric. Make the warning message agree with
this too.

7c0631d494 perf test: Fix offcpu test prev_state check 
On Fedora 36, the 'perf record' offcpu profiling tests are failing.  It

was because the BPF checks the prev task's state being S or D but
actually it has more bits set.  Let's check the LSB 8 bits for the
purpose of offcpu profiling.

   ----

Based on above logs, we could see some of the hv-24x7 metric events
fails, and logs suggest to run the metric event with -a option.  This
change happened after the commit a4b8cfcabb ("perf stat: Delay
metric parsing"), which delayed the metric parsing phase and now before
metric parsing phase perf tool identifies, whether target is system-wide
or not. With this change, perf_event_open will fails with workload
monitoring for uncore events as expected.

The perf all metric test case fails as some of the hv-24x7 metric events
may need bigger workload with system wide monitoring to get the data.
Fix this issue by changing current system wide check from true workload
to sleep 0.01 workload.

Result with the patch changes in powerpc:

  98: perf all metrics test : Ok

Fixes: a4b8cfcabb ("perf stat: Delay metric parsing")

cf26e043c2 perf vendor events power10: Add JSON metric events to present CPI stall cycles in powerpc 
Power10 Performance Monitoring Unit (PMU) provides events to understand
stall cycles of different pipeline stages.  These events along with
completed instructions provides useful metrics for application tuning.

Patch implements the JSON changes to collect counter statistics to
present the high level CPI stall breakdown metrics. New metric group is
named as "CPI_STALL_RATIO" and this new metric group presents these
stall metrics:

- DISPATCHED_CPI ( Dispatch stall cycles per insn )
- ISSUE_STALL_CPI ( Issue stall cycles per insn )
- EXECUTION_STALL_CPI ( Execution stall cycles per insn )
- COMPLETION_STALL_CPI ( Completition stall cycles per insn )

To avoid multipling of events, PM_RUN_INST_CMPL event has been modified
to use PMC5(performance monitoring counter5) instead of PMC4. This
change is needed, since completion stall event is using PMC4.

Usage example:

 ./perf stat --metric-no-group -M CPI_STALL_RATIO <workload>

 Performance counter stats for 'workload':

    63,056,817,982      PM_CMPL_STALL                    #     0.28 COMPLETION_STALL_CPI
 1,743,988,038,896      PM_ISSUE_STALL                   #     7.73 ISSUE_STALL_CPI
   225,597,495,030      PM_RUN_INST_CMPL                 #     6.18 DISPATCHED_CPI
                                                  #    37.48 EXECUTION_STALL_CPI
 1,393,916,546,654      PM_DISP_STALL_CYC
 8,455,376,836,463      PM_EXEC_STALL

"--metric-no-group" is used for forcing PM_RUN_INST_CMPL to be scheduled
in all group for more accuracy.

7e55b95651 perf intel-pt: Synthesize cycle events 
There is no good reason why we cannot synthesize "cycle" events from
Intel PT just as we can synthesize "instruction" events, in particular
when CYC packets are available. This enables using PT to getting much
more accurate cycle profiles than regular sampling (record -e cycles)
when the work last for very short periods (<10 ms).  Thus, add support
for this, based off of the existing IPC calculation framework. The new
option to --itrace is "y" (for cYcles), as c was taken for calls. Cycle
and instruction events can be synthesized together, and are by default.

The only real caveat is that CYC packets are only emitted whenever some
other packet is, which in practice is when a branch instruction is
encountered (and not even all branches). Thus, even at no subsampling
(e.g. --itrace=y0ns), it is impossible to get more accuracy than a
single basic block, and all cycles spent executing that block will get
attributed to the branch instruction that ends the packet.  Thus, one
cannot know whether the cycles came from e.g. a specific load, a
mispredicted branch, or something else. When subsampling (which is the
default), the cycle events will get smeared out even more, but will
still be generally useful to attribute cycle counts to functions.

1470a108a6 perf c2c: Add report option to show false sharing in adjacent cachelines 
Many platforms have feature of adjacent cachelines prefetch, when it is
enabled, for data in RAM of 2 cachelines (2N and 2N+1) granularity, if
one is fetched to cache, the other one could likely be fetched too,
which sort of extends the cacheline size to double, thus the false
sharing could happens in adjacent cachelines.

0Day has captured performance changed related with this [1], and some
commercial software explicitly makes its hot global variables 128 bytes
aligned (2 cache lines) to avoid this kind of extended false sharing.

So add an option "--double-cl" for 'perf c2c report' to show false
sharing in double cache line granularity, which acts just like the
cacheline size is doubled. There is no change to c2c record. The
hardware events of shared cacheline are still per cacheline, and this
option just changes the granularity of how events are grouped and
displayed.

In the 'perf c2c report' output below (will-it-scale's 'pagefault2' case
on old kernel):

Removed -a, leaving just as --double-cl, as this probably is not used so
frequently and perhaps will be even auto-detected if we manage to record

The reason is that record__bytes_written accesses the freed memory rec->thread_data,
The process is as follows:
  __cmd_record
    -> record__free_thread_data
      -> zfree(&rec->thread_data)         // free rec->thread_data
    -> record__synthesize
      -> perf_event__synthesize_id_index
        -> process_synthesized_event
          -> record__write
            -> record__bytes_written      // access rec->thread_data

We add a member variable "thread_bytes_written" in the struct "record"
to save the data size written by the threads.

37f322cd58 perf stat: Avoid merging/aggregating metric counts twice 
The added perf_stat_merge_counters combines uncore counters. When
metrics are enabled, the counts are merged into a metric_leader via the
stat-shadow saved_value logic. As the leader now is passed an aggregated
count, it leads to all counters being added together twice and counts
appearing approximately doubled in metrics.

This change disables the saved_value merging of counts for evsels that
are merged. It is recommended that later changes remove the saved_value
entirely as the two layers of aggregation in the code is confusing.

  };

but does not adjust the usage of this function prototype in util/pfm.c.
In file util/pfm.c function print_event() is still invoked with 13

When I adjust the file util/pfm.c as in this patch, the build works file.
Please check this patch for correctness, I have just fixed the compile

3477f079fe perf lock contention: Add -o/--lock-owner option 
When there're many lock contentions in the system, people sometimes want
to know who caused the contention, IOW who's the owner of the locks.

The -o/--lock-owner option tries to follow the lock owners for the
contended mutexes and rwsems from BPF, and then attributes the
contention time to the owner instead of the waiter.  It's a best effort
approach to get the owner info at the time of the contention and doesn't
guarantee to have the precise tracking of owners if it's changing over
time.

Currently it only handles mutex and rwsem that have owner field in their
struct and it basically points to a task_struct that owns the lock at
the moment.

Technically its type is atomic_long_t and it comes with some LSB bits
used for other meanings.  So it needs to clear them when casting it to a
pointer to task_struct.

Also the atomic_long_t is a typedef of the atomic 32 or 64 bit types
depending on arch which is a wrapper struct for the counter value.  I'm
not aware of proper ways to access those kernel atomic types from BPF so
I just read the internal counter value directly.  Please let me know if
there's a better way.

When -o/--lock-owner option is used, it goes to the task aggregation
mode like -t/--threads option does.  However it cannot get the owner for
other lock types like spinlock and sometimes even for mutex.

34266f904a perf test bpf: Skip test if kernel-debuginfo is not present 
Perf BPF filter test fails in environment where "kernel-debuginfo"
is not installed.

Test failure logs:

  <<>>
  42: BPF filter                            :
  42.1: Basic BPF filtering                 : Ok
  42.2: BPF pinning                         : Ok
  42.3: BPF prologue generation             : FAILED!
  <<>>

Enabling verbose option provided debug logs, which says debuginfo
needs to be installed. Snippet of verbose logs:

  <<>>
  42.3: BPF prologue generation                                       :
  --- start ---
  test child forked, pid 28218
  <<>>
  Rebuild with CONFIG_DEBUG_INFO=y, or install an appropriate debuginfo
  package.
  bpf_probe: failed to convert perf probe events
  Failed to add events selected by BPF
  test child finished with -1
  ---- end ----
  BPF filter subtest 3: FAILED!
  <<>>

Here the subtest "BPF prologue generation" failed and logs shows
debuginfo is needed. After installing kernel-debuginfo package, testcase
passes.

The "BPF prologue generation" subtest failed because, the do_test()
returns TEST_FAIL without checking the error type returned by
parse_events_load_bpf_obj().

parse_events_load_bpf_obj() can also return error of type -ENODATA
incase kernel-debuginfo package is not installed. Fix this by adding
check for -ENODATA error.

Test result after the patch changes:

Test failure logs:

  <<>>
  42: BPF filter                 :
  42.1: Basic BPF filtering      : Ok
  42.2: BPF pinning              : Ok
  42.3: BPF prologue generation  : Skip (clang/debuginfo isn't installed or environment missing BPF support)

67ef66bad4 perf probe: Update the exit error codes in function try_to_find_probe_trace_event 
try_to_find_probe_trace_events() uses return error code as ENOENT in two
places.

First place is after open_debuginfo() when opening debuginfo fails and
secondly, after when not finding the probe point.

This function is invoked during BPF load and there are other exit points
in this code path which returns ENOENT. This makes it difficult to
understand the exact reason for exit.

Patches changes the exit code from ENOENT to:

- ENODATA when it fails to find debuginfo

- ENODEV when it fails to find probe point

ee739f132f perf test bpf: Check for libtraceevent support 
The "bpf" tests fails in environment with missing libtraceevent support
as below:

  # ./perf test 36
  36: BPF filter                          :
  36.1: Basic BPF filtering               : FAILED!
  36.2: BPF pinning                       : FAILED!
  36.3: BPF prologue generation           : FAILED!

The environment has clang but missing the libtraceevent devel. Hence
perf is compiled without libtraceevent support.

Detailed logs:
	./perf test -v "Basic BPF filtering"

	Failed to add BPF event syscalls:sys_enter_epoll_pwait
	bpf: tracepoint call back failed, stop iterate
	Failed to add events selected by BPF

The bpf tests tris to add probe event which fails at
"parse_events_add_tracepoint" function due to missing libtraceevent. Add
check for "HAVE_LIBTRACEEVENT" in the "tests/bpf.c" before proceeding
with the test.

With the change,

	# ./perf test 36
 	36: BPF filter                    :
 	36.1: Basic BPF filtering         : Skip (not compiled in or missing libtraceevent support)
 	36.2: BPF pinning                 : Skip (not compiled in or missing libtraceevent support)
 	36.3: BPF prologue generation     : Skip (not compiled in or missing libtraceevent support)
