Merge tag 'perf-tools-for-v6.6-1-2023-09-05' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools

Pull perf tools updates from Arnaldo Carvalho de Melo:
"perf tools maintainership:

- Add git information for perf-tools and perf-tools-next trees and
branches to the MAINTAINERS file. That is where development now
takes place and myself and Namhyung Kim have write access, more
people to come as we emulate other maintainer groups.

perf record:

- Record kernel data maps when 'perf record --data' is used, so that
global variables can be resolved and used in tools that do data
profiling.

perf trace:

- Remove the old, experimental support for BPF events in which a .c
file was passed as an event: "perf trace -e hello.c" to then get
compiled and loaded.

The only known usage for that, that shipped with the kernel as an
example for such events, augmented the raw_syscalls tracepoints and
was converted to a libbpf skeleton, reusing all the user space
components and the BPF code connected to the syscalls.

In the end just the way to glue the BPF part and the user space
type beautifiers changed, now being performed by libbpf skeletons.

The next step is to use BTF to do pretty printing of all syscall
types, as discussed with Alan Maguire and others.

Now, on a perf built with BUILD_BPF_SKEL=1 we get most if not all
path/filenames/strings, some of the networking data structures,
perf_event_attr, etc, i.e. systemwide tracing of nanosleep calls
and perf_event_open syscalls while 'perf stat' runs 'sleep' for 5
seconds:

perf annotate:

- Building with binutils' libopcode now is opt-in (BUILD_NONDISTRO=1)
for licensing reasons, and we missed a build test on
tools/perf/tests makefile.

Since we now default to NDEBUG=1, we ended up segfaulting when
building with BUILD_NONDISTRO=1 because a needed initialization
routine was being "error checked" via an assert.

Fix it by explicitly checking the result and aborting instead if it
fails.

We better back propagate the error, but at least 'perf annotate' on
samples collected for a BPF program is back working when perf is
built with BUILD_NONDISTRO=1.

perf report/top:

- Add back TUI hierarchy mode header, that is seen when using 'perf
report/top --hierarchy'.

- Fix the number of entries for 'e' key in the TUI that was
preventing navigation of lines when expanding an entry.

perf report/script:

- Support cross platform register handling, allowing a perf.data file
collected on one architecture to have registers sampled correctly
displayed when analysis tools such as 'perf report' and 'perf
script' are used on a different architecture.

- Fix handling of event attributes in pipe mode, i.e. when one uses:

perf record -o - | perf report -i -

When no perf.data files are used.

- Handle files generated via pipe mode with a version of perf and
then read also via pipe mode with a different version of perf,
where the event attr record may have changed, use the record size
field to properly support this version mismatch.

perf probe:

- Accessing global variables from uprobes isn't supported, make the
error message state that instead of stating that some minimal
kernel version is needed to have that feature. This seems just a
tool limitation, the kernel probably has all that is needed.

perf tests:

- Fix a reference count related leak in the dlfilter v0 API where the
result of a thread__find_symbol_fb() is not matched with an
addr_location__exit() to drop the reference counts of the resolved
components (machine, thread, map, symbol, etc). Add a dlfilter test
to make sure that doesn't regresses.

- Lots of fixes for the 'perf test' written in shell script related
to problems found with the shellcheck utility.

- Fixes for 'perf test' shell scripts testing features enabled when
perf is built with BUILD_BPF_SKEL=1, such as 'perf stat' bpf
counters.

- Add perf record sample filtering test, things like the following
example, that gets implemented as a BPF filter attached to the
event:

# perf record -e task-clock -c 10000 --filter 'ip < 0xffffffff00000000'

- Improve the way the task_analyzer test checks if libtraceevent is
linked, using 'perf version --build-options' instead of the more
expensinve 'perf record -e "sched:sched_switch"'.

- Add support for riscv in the mmap-basic test. (This went as well
via the RiscV tree, same contents).

libperf:

- Implement riscv mmap support (This went as well via the RiscV tree,
same contents).

perf script:

- New tool that converts perf.data files to the firefox profiler
format so that one can use the visualizer at
https://profiler.firefox.com/. Done by Anup Sharma as part of this
year's Google Summer of Code.

One can generate the output and upload it to the web interface but
Anup also automated everything:

perf script gecko -F 99 -a sleep 60

- Support syscall name parsing on arm64.

- Print "cgroup" field on the same line as "comm".

perf bench:

- Add new 'uprobe' benchmark to measure the overhead of uprobes
with/without BPF programs attached to it.

- breakpoints are not available on power9, skip that test.

perf stat:

- Add #num_cpus_online literal to be used in 'perf stat' metrics, and
add this extra 'perf test' check that exemplifies its purpose:

TEST_ASSERT_VAL("#num_cpus_online",
expr__parse(&num_cpus_online, ctx, "#num_cpus_online") == 0);
TEST_ASSERT_VAL("#num_cpus", expr__parse(&num_cpus, ctx, "#num_cpus") == 0);
TEST_ASSERT_VAL("#num_cpus >= #num_cpus_online", num_cpus >= num_cpus_online);

Miscellaneous:

- Improve tool startup time by lazily reading PMU, JSON, sysfs data.

- Improve error reporting in the parsing of events, passing YYLTYPE
to error routines, so that the output can show were the parsing
error was found.

- Add 'perf test' entries to check the parsing of events
improvements.

- Fix various leak for things detected by -fsanitize=address, mostly
things that would be freed at tool exit, including:

- Free evsel->filter on the destructor.

- Allow tools to register a thread->priv destructor and use it in
'perf trace'.

- Free evsel->priv in 'perf trace'.

- Free string returned by synthesize_perf_probe_point() when the
caller fails to do all it needs.

- Adjust various compiler options to not consider errors some
warnings when building with broken headers found in things like
python, flex, bison, as we otherwise build with -Werror. Some for
gcc, some for clang, some for some specific version of those, some
for some specific version of flex or bison, or some specific
combination of these components, bah.

- Allow customization of clang options for BPF target, this helps
building on gentoo where there are other oddities where BPF targets
gets passed some compiler options intended for the native build, so
building with WERROR=0 helps while these oddities are fixed.

- Dont pass ERR_PTR() values to perf_session__delete() in 'perf top'
and 'perf lock', fixing some segfaults when handling some odd
failures.

- Add LTO build option.

- Fix format of unordered lists in the perf docs
(tools/perf/Documentation)

- Overhaul the bison files, using constructs such as YYNOMEM.

- Remove unused tokens from the bison .y files.

- Add more comments to various structs.

- A few LoongArch enablement patches.

Vendor events (JSON):

- Add JSON metrics for Yitian 710 DDR (aarch64). Things like:

EventName, BriefDescription
visible_window_limit_reached_rd, "At least one entry in read queue reaches the visible window limit.",
visible_window_limit_reached_wr, "At least one entry in write queue reaches the visible window limit.",
op_is_dqsosc_mpc , "A DQS Oscillator MPC command to DRAM.",
op_is_dqsosc_mrr , "A DQS Oscillator MRR command to DRAM.",
op_is_tcr_mrr , "A Temperature Compensated Refresh(TCR) MRR command to DRAM.",

- Add AmpereOne metrics (aarch64).

- Update N2 and V2 metrics (aarch64) and events using Arm telemetry
repo.

- Update scale units and descriptions of common topdown metrics on
aarch64. Things like:
- "MetricExpr": "stall_slot_frontend / (#slots * cpu_cycles)",
- "BriefDescription": "Frontend bound L1 topdown metric",
+ "MetricExpr": "100 * (stall_slot_frontend / (#slots * cpu_cycles))",
+ "BriefDescription": "This metric is the percentage of total slots that were stalled due to resource constraints in the frontend of the processor.",

- Update events for intel: meteorlake to 1.04, sapphirerapids to
1.15, Icelake+ metric constraints.

- Update files for the power10 platform"

perf test stat_bpf_counters_cgrp: Enhance perf stat cgroup BPF counter test

It has system-wide test and cpu-list test but the cpu-list test fails
sometimes. It runs sleep command on CPU1 and measure both user.slice
and system.slice cgroups by default (on systemd-based systems).

But if the system was idle enough, sometime the system.slice gets no
count and it makes the test failing. Maybe that's because it only looks
at the CPU1, let's add CPU0 to increase the chance it finds some tasks.

- Include program header in ELF files generated for JIT files, so that
they can be opened by tools using elfutils libraries.

- Enter namespaces when synthesizing build-ids.

- Fix some bugs related to a recent cpu_map overhaul where we should be
using an index and not the cpu number.

- Fix BPF program ELF section name, using the naming expected by libbpf
when using BPF counters in 'perf stat'.

- Add a new test for perf stat cgroup BPF counter.

- Adjust check on 'perf test wp' for older kernels, where the
PERF_EVENT_IOC_MODIFY_ATTRIBUTES ioctl isn't supported.

- Sync x86 cpufeatures with the kernel sources, no changes in tooling.
