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"

Merge x86/urgent into x86/fpu
Pick up dependent changes which either went mainline (x86/urgent is based on -rc7 and that contains them) as urgent fixes and the current x86/urgent branch which contains two more urgent fixes, so that the bigger FPU rework can base off ontop.

Merge series "Extend regulator notification support" from Matti Vaittinen <matti.vaittinen@fi.rohmeurope.com>:
Extend regulator notification support
This series extends the regulator notification and error flag support. Initial discussion on the topic can be found here: https://lore.kernel.org/lkml/6046836e22b8252983f08d5621c35ececb97820d.camel@fi.rohmeurope.com/
In a nutshell - the series adds:
1. WARNING level events/error flags. (Patch 3) Current regulator 'ERROR' event notifications for over/under voltage, over current and over temperature are used to indicate condition where monitored entity is so badly "off" that it actually indicates a hardware error which can not be recovered. The most typical hanling for that is believed to be a (graceful) system-shutdown. Here we add set of 'WARNING' level flags to allow sending notifications to consumers before things are 'that badly off' so that consumer drivers can implement recovery-actions. 2. Device-tree properties for specifying limit values. (Patches 1, 5) Add limits for above mentioned 'ERROR' and 'WARNING' levels (which send notifications to consumers) and also for a 'PROTECTION' level (which will be used to immediately shut-down the regulator(s) W/O informing consumer drivers. Typically implemented by hardware). Property parsing is implemented in regulator core which then calls callback operations for limit setting from the IC drivers. A warning is emitted if protection is requested by device tree but the underlying IC does not support configuring requested protection. 3. Helpers which can be registered by IC. (Patch 4) Target is to avoid implementing IRQ handling and IRQ storm protection in each IC driver. (Many of the ICs implementin these IRQs do not allow masking or acking the IRQ but keep the IRQ asserted for the whole duration of problem keeping the processor in IRQ handling loop). 4. Emergency poweroff function (refactored out of the thermal_core to kernel/reboot.c) which is called if IC fires error IRQs but IC reading fails and given retry-count is exceeded. (Patches 2, 4) Please note that the mutex in the emergency shutdown was replaced by a simple atomic in order to allow call from any context.
The helper was attempted to be done so it could be used to implement roughly same logic as is used in qcom-labibb regulator. This means amongst other things a safety shut-down if IC registers are not readable. Using these shut-down retry counters are optional. The idea is that the helper could be also used by simpler ICs which do not provide status register(s) which can be used to check if error is still active.
ICs which do not have such status register can simply omit the 'renable' callback (and retry-counts etc) - and helper assumes the situation is Ok and re-enables IRQ after given time period. If problem persists the handler is ran again and another notification is sent - but at least the delay allows processor to avoid IRQ loop.
Patch 7 takes this notification support in use at BD9576MUF. Patch 8 is related to MFD change which is not really related to the RFC here. It was added to this series in order to avoid potential conflicts. Patch 9 adds a maintainers entry.
Changelog v10-RESEND: - rebased on v5.13-rc4 Changelog v10: - rebased on v5.13-rc2 - Move rdev_*() print macros to the internal.h and use rdev_dbg() from irq_helpers.c - Export rdev_get_name() and move it from coupler.h to driver.h for others to use. (It was already in coupler.h but not exported - usage was limited and coupler.h does not sound like optimal place as rdev_name is not only used by coupled regulators) - Send all regulator notifications from irq_helpers.c at one OR'd event for the sake of simplicity. For BD9576 this does not matter as it has own IRQ for each event case. Header defining events says they may be OR'd. - Change WARN() at protection shutdown to pr_emerg as suggested by Petr. Changelog v9: - rebases on v5.13-rc1 - Update thermal documentation - Fix regulator notification event number Changelog v8: - split shutdown API adding and thermal core taking it in use to own patches. - replace the spinlock with atomic when ensuring the emergency shutdown is only called once. Changelog v7: general: - rebased on v5.12-rc7 - new patch for refactoring the hw-failure reboot logic out of thermal_core.c for others to use. notification helpers: - fix regulator error_flags query - grammar/typos - do not BUG() but attempt to shut-down the system - use BITS_PER_TYPE()
Changelog v6: Add MAINTAINERS entry Changes to IRQ notifiers - move devm functions to drivers/regulator/devres.c - drop irq validity check - use devm_add_action_or_reset() - fix styling issues - fix kerneldocs
Changelog v5: - Fix the badly formatted pr_emerg() call.
Changelog v4: - rebased on v5.12-rc6 - dropped RFC - fix external FET DT-binding. - improve prints for cases when expecting HW failure. - styling and typos
Changelog v3: Regulator core: - Fix dangling pointer access at regulator_irq_helper() stpmic1_regulator: - fix function prototype (compile error) bd9576-regulator: - Update over current limits to what was given in new data-sheet (REV00K) - Allow over-current monitoring without external FET. Set limits to values given in data-sheet (REV00K).
Changelog v2: Generic: - rebase on v5.12-rc2 + BD9576 series - Split devm variant of delayed wq to own series Regulator framework: - Provide non devm variant of IRQ notification helpers - shorten dt-property names as suggested by Rob - unconditionally call map_event in IRQ handling and require it to be populated BD9576 regulators: - change the FET resistance property to micro-ohms - fix voltage computation in OC limit setting
