perf vendor events: Update Intel sapphirerapids
Events are updated to v1.06 the core metrics are based on TMA 4.4 full.
Use script at:
https://github.com/intel/event-converter-for-linux-perf/blob/master/download_and_gen.py
with updates at:
https://github.com/captain5050/event-converter-for-linux-perf
Updates include:
- Rename of topdown TMA metrics from Frontend_Bound to tma_frontend_bound.
- Addition of all 6 levels of TMA metrics. Previously metrics
involving topdown events were dropped. Child metrics are placed in
a group named after their parent allowing children of a metric to
be easily measured using the metric name with a _group suffix.
- ## and ##? operators are correctly expanded.
- The locate-with column is added to the long description describing
a sampling event.
- Metrics are written in terms of other metrics to reduce the
expression size and increase readability.
- Latest metrics from: https://github.com/intel/perfmon-metrics
Tested with 'perf test':
10: PMU events :
10.1: PMU event table sanity : Ok
10.2: PMU event map aliases : Ok
10.3: Parsing of PMU event table metrics : Ok
10.4: Parsing of PMU event table metrics with fake PMUs : Ok

with updates at:

Updates include:
- Removal of ScaleUnit from uncore events by Zhengjun Xing
<zhengjun.xing@linux.intel.com>.
- Rename of topdown TMA metrics from Frontend_Bound to tma_frontend_bound.
- _SMT suffix metrics are dropped as the #SMT_On and #EBS_Mode are
correctly expanded in the single main metric.
- Addition of all 6 levels of TMA metrics. Child metrics are placed
in a group named after their parent allowing children of a metric
to be easily measured using the metric name with a _group suffix.
- ## and ##? operators are correctly expanded.
- The locate-with column is added to the long description describing
a sampling event.
- Metrics are written in terms of other metrics to reduce the
expression size and increase readability.

This currently fails to parse as the left hand side if expression needs

there is already nowhere else using these macros, also no macros called

perf tools: Fix empty version number when building outside of a git repo
When perf is built in a full source tree that is not a git repository,
e.g. from a kernel source tarball, `perf version` will print empty tag
and commit strings:
$ perf version
perf version
Currently the tag version is only generated from the root Makefile when
building in a git repository. If PERF-VERSION-FILE has not been
generated and the source tree is not in a git repository, then
PERF-VERSION-GEN will return an empty version.
The problem can be reproduced with the following steps:
$ wget https://git.kernel.org/torvalds/t/linux-6.0-rc7.tar.gz
$ tar -xf linux-6.0-rc7.tar.gz && cd linux-6.0-rc7
$ make -C tools/perf
$ tools/perf/perf -v
perf version
Builds from tarballs generated with `make perf-tar-src-pkg` are not
impacted by this issue as PERF-VERSION-FILE is included in the archive.
The perf RPM provided by Fedora for 5.18+ is experiencing this problem.
Package build logs[0] show that the build is attempting to fall back on
PERF-VERSION-FILE, but it is not present.
To resolve this, revert back to the previous logic of using the kernel
Makefile version if not in a git repository and PERF-VERSION-FILE does
not exist.

perf trace: Fix show_arg_names not working for tp arg names
trace__fprintf_tp_fields() will always print arg names because when
implemented it is forced to print arg_names with:
(1 || trace->show_arg_names)
So the printing looks like:
> cat ~/.perfconfig
[trace]
show_arg_names = no
> perf trace -e syscalls:*mmap sleep 1
0.000 sleep/1119 syscalls:sys_enter_mmap(NULL, 8192, READ|WRITE, PRIVATE|ANONYMOUS)

Although the comment said that perhaps we need a show_tp_arg_names.
I don't think it's necessary to control them separately because it's not
so clean that part of the log shows arg names but other not.
Also when we are tracing functions it's rare to especially distinguish
syscalls and tp trace.
Only use one option to control arg names printing is more resonable and
simple. So remove the force condition and commit.
After fix:
> perf trace -e syscalls:*mmap sleep 1

perf lock contention: Allow to change stack depth and skip
It needs stack traces to find callers of locks. To minimize the
performance overhead it only collects up to 8 entries for each stack
trace. And it skips first 3 entries as they came from BPF, tracepoint
and lock functions which are not interested for most users.
But it turned out that those numbers are different in some
configuration. Using fixed number can result in non meaningful caller
names. Let's make them adjustable with --stack-depth and --skip-stack
options.
On my setup, the default output is like below:
# /perf lock con -ab -F contended,wait_total sleep 3
contended total wait type caller
28 4.55 ms rwlock:W __bpf_trace_contention_begin+0xb
33 1.67 ms rwlock:W __bpf_trace_contention_begin+0xb

60 240.54 us rwsem:R __bpf_trace_contention_begin+0xb
27 64.45 us spinlock __bpf_trace_contention_begin+0xb
If I change the stack skip to 5, the result will be like:
# perf lock con -ab -F contended,wait_total --stack-skip 5 sleep 3
contended total wait type caller

perf topology: Add core_wide
It is possible to optimize metrics when all SMT threads (CPUs) on a
core are measuring events in system wide mode. For example, TMA
metrics defines CORE_CLKS for Sandybrdige as:
if SMT is disabled:
CPU_CLK_UNHALTED.THREAD
if SMT is enabled and recording on all SMT threads:
CPU_CLK_UNHALTED.THREAD_ANY / 2
if SMT is enabled and not recording on all SMT threads:
(CPU_CLK_UNHALTED.THREAD/2)*
(1+CPU_CLK_UNHALTED.ONE_THREAD_ACTIVE/CPU_CLK_UNHALTED.REF_XCLK )
That is two more events are necessary when not gathering counts on all
SMT threads. To distinguish all SMT threads on a core vs system wide
(all CPUs) call the new property core wide. Add a core wide test that
determines the property from user requested CPUs, the topology and
system wide. System wide is required as other processes running on a
SMT thread will change the counts.

As we want to see the number of lost samples in the perf report, set the

perf branch: Add system error and not in transaction branch types
This updates the perf tool with generic branch type classification with
two new branch types i.e system error (PERF_BR_SERROR) and not in
transaction (PERF_BR_NO_TX) which got updated earlier in the kernel.
This also updates corresponding branch type strings in
branch_type_name().
Committer notes:
At perf tools merge time this is only on PeterZ's tree, at:
git://git.kernel.org/pub/scm/linux/kernel/git/peterz/queue.git perf/core
So for testing one has to build a kernel with that branch, then test
the tooling side from:
git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git perf/core
