perf vendor events intel: Refresh sapphirerapids metrics and events
Update the sapphirerapids metrics and events using the new tooling from: https://github.com/intel/perfmon The metrics are unchanged but the formulas differ due to parentheses, use of exponents and removal of redundant operations like "* 1". The order of metrics varies as TMA metrics are first converted and then removed if perfmon versions are found. The events are updated to 1.09, in particular uncore, with fixes to uncore events and improved descriptions. The formatting changes increase consistency across the json files.

perf test pmu-events: Fake PMU metric workaround
We test metrics with fake events with fake values. The fake values may yield division by zero and so we count both up and down to try to avoid this.

perf hist: Improve srcline sort key performance
The sort_entry->cmp() will be called for eventy sample data to find a matching entry. When it has 'srcline' sort key, that means it needs to call addr2line or libbfd everytime. This is not optimal because many samples will have same address and it just can call addr2line once. So postpone the actual srcline check to the sort_entry->collpase() and compare addresses in ->cmp(). Also it needs to add ->init() callback to make sure it has srcline info. If a sample has a unique data, chances are the entry can be sorted out by other (previous) keys and callbacks in sort_srcline never called.

perf test: Fix "all PMU test" to skip parametrized events
Parametrized events are not only a powerpc domain. They occur on other
platforms too (e.g. aarch64). They should be ignored in this testcase,
since proper setup of the parameters is out of scope of this script.
Let's not filter them out by PMU name, but rather based on the fact that
they expect a parameter.

perf lock contention: Add -Y/--type-filter option
The -Y/--type-filter option is to filter the result for specific lock
types only. It can accept comma-separated values. Note that it would
accept type names like one in the output. spinlock, mutex, rwsem:R and
so on.
For RW-variant lock types, it converts the name to the both variants.
In other words, "rwsem" is same as "rwsem:R,rwsem:W". Also note that
"mutex" has two different encoding - one for sleeping wait, another for
optimistic spinning. Add "mutex-spin" entry for the lock_type_table so
that we can add it for "mutex" under the table.

perf debug: Set debug_peo_args and redirect_to_stderr variable to correct values in perf_quiet_option()
When perf uses quiet mode, perf_quiet_option() sets the 'debug_peo_args'

Merge tag 'parisc-for-6.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull parisc updates from Helge Deller:
"There is one noteable patch, which allows the parisc kernel to use the
same MADV_xxx constants as the other architectures going forward. With
that change only alpha has one entry left (MADV_DONTNEED is 6 vs 4 on
others) which is different. To prevent an ABI breakage, a wrapper is
included which translates old MADV values to the new ones, so existing
userspace isn't affected. Reason for that patch is, that some
applications wrongly used the standard MADV_xxx values even on some
non-x86 platforms and as such those programs failed to run correctly
on parisc (examples are qemu-user, tor browser and boringssl).
Then the kgdb console and the LED code received some fixes, and some
0-day warnings are now gone. Finally, the very last compile warning
which was visible during a kernel build is now fixed too (in the vDSO
code).
The majority of the patches are tagged for stable series and in
summary this patchset is quite small and drops more code than it adds:

parisc: Align parisc MADV_XXX constants with all other architectures
Adjust some MADV_XXX constants to be in sync what their values are on all other platforms. There is currently no reason to have an own numbering on parisc, but it requires workarounds in many userspace sources (e.g. glibc, qemu, ...) - which are often forgotten and thus introduce bugs and different behaviour on parisc. A wrapper avoids an ABI breakage for existing userspace applications by translating any old values to the new ones, so this change allows us to move over all programs to the new ABI over time.

perf tools changes for v6.2: 1st batch
Libraries:
- Drop the old copy of libtraceevent in tools/lib/traceevent/ now that all major distros
ship it from its external repository.
This is now just another feature detection, emitting a warning when the
libtraceevent-dev[el] package isn't installed, disabling the build of perf features
and tools that strictly require parsing things from tracefs while keeping
the core functionality present and working with a subset of the events, the
most used ones like CPU cycles, hardware cache and also vendor events, etc.
This was tested with lots of containers for Fedora, Debian, OpenSUSE, Alpine Linux,
Ubuntu, with cross builds, etc.
Build:
- Update to C standard to gnu11, like was done for the kernel.
- Install the tools/lib/ libraries locally instead of having headers searched
directly from the source code directories, to help the cases where we can
build either from in-kernel source libraries or from the same library shipped
as a distro package, as is the case with libbpf and was the case with
libtraceevent.
perf stat:
- Do not delay the workload with --delay, the delay is just for starting to count
the events, to skip noise at workload startup.
- When we have events for each cgroup, the metric should be printed for each
cgroup separately.
$ perf stat -a --for-each-cgroup system.slice,user.slice --metric-only sleep 1
Performance counter stats for 'system wide':
GHz insn per cycle branch-misses of all branches
system.slice 3.792 0.61 3.24%
user.slice 3.661 2.32 0.37%
- Fix printing field separator in CSV metrics output.
- Fix --metric-only --json output.
- Fix summary output in CSV with --metric-only.
- Update event group check for support of uncore event.
perf test:
- Stop requiring a C toolchain in shell tests, instead add a workload option that has
all the previously C snippets built as part of 'perf test -w' that then get used in
the 'perf test' shell scripts.
- Add event group test for events in multiple PMUs
- The "kernel lock contention analysis" test should not print warnings in quiet mode.
- Add attr tests for ARM64's new VG register.
- Fix record test on KVM guests, as using precise flag with the
br_inst_retired.near_call event causes the test fail on KVM guests, even when
the guests have PMU forwarding enabled and the event itself is supported, so just
remove the precise flag from the event.
- Add mechanism for skipping attr tests on specific kernel versions where it is known that
these checks will fail.
- Skip watchpoint tests if no watchpoints available.
- Add more Intel PT 'perf test' entries: hybrid CPUs, split the packet decoder
into a suite of subtests.
perf script:
- Introduce task analyzer python script, where one first records some events:
Recording can be done in two ways:
$ perf script record tasks-analyzer -- sleep 10
$ perf record -e sched:sched_switch -a -- sleep 10
The script can parse any perf.data files, as long as it has sched:sched_switch events,
other events will be ignored.
The most simple report use case is to just call the script without arguments.
Runtime is the time the task was running on the CPU, Time Out-In is the time
between the process being scheduled *out* and scheduled back *in*. So the last
time span between two executions:

perf record:
- Add remaining branch filters: "no_cycles", "no_flags" & "hw_index", to be
used with hardware such as Intel's LBR that allows things like stitching
stacks of two samples to overcome the limits of the number of LBR registers.
Symbol resolution:
- Handle .debug files created with 'objcopy --only-keep-debug', where program
headers are zeroed and thus can't be used for adjustments, use the info in
the runtime_ss (runtime ELF) instead.
perf trace:
- Add BPF based augmenter for the 'perf_event_open's 'struct perf_event_attr' argument.
- Add BPF based augmenter for the 'clock_gettime's 'struct timespec' argument.
- In both cases the syscall tracepoint has just the pointer value, we
need to hook a BPF program to collect the pointer contents, and then,
in userspace, pretty print it in 'perf trace'.
perf list:
- Introduce JSON output of events.
- Streamline how the expression specifying what events should be shown is handled,
fixing several corner cases, such as the metric filter that is specified as a glob
but was using strstr().
perf probe:
- Fix to avoid crashing if DW_AT_decl_file is NULL, coping with clang generating
DWARF5 like that.
- Use dwarf_attr_integrate() as generic DWARF attr accessor as it supersedes dwarf_attr(),
supporting abstact origin DIEs.
perf inject:
- Set PERF_RECORD_MISC_BUILD_ID_SIZE in the PERF_RECORD_HEADER_BUILD_ID so that
perf.data readers can get the real build-id size and avoid trailing zeros.
perf data:
- Add tracepoint fields when converting a perf.data file to JSON.
arm64:
- Fix mksyscalltbl, don't lose syscalls due to sort -nu.
- Add Arm Neoverse V2 PMU events.
riscv:
- Add riscv sbi firmware std event files.

Miscellaneous:
- Periodic sanitization of headers, adding missing includes, removing needless ones,
creating new ones, etc.
- Use sig_atomic_t for signal handlers to avoid undefined behaviour in all perf
tools.
- Fixes for libbpf 1.0+ compatibility (maps, etc) on 'perf trace' BPF examples.
- Remove some old perf bpf examples, leave the best ones that demonstrate how
to associate BPF functions to points in the kernel.

Merge tag 'perf-tools-for-v6.2-1-2022-12-16' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux
Pull perf tools updates from Arnaldo Carvalho de Melo:
"Libraries:
- Drop the old copy of libtraceevent in tools/lib/traceevent/ now
that all major distros ship it from its external repository.
This is now just another feature detection, emitting a warning when
the libtraceevent-dev[el] package isn't installed, disabling the
build of perf features and tools that strictly require parsing
things from tracefs while keeping the core functionality present
and working with a subset of the events, the most used ones like
CPU cycles, hardware cache and also vendor events, etc.
This was tested with lots of containers for Fedora, Debian,
OpenSUSE, Alpine Linux, Ubuntu, with cross builds, etc.
Build:
- Update to C standard to gnu11, like was done for the kernel.
- Install the tools/lib/ libraries locally instead of having headers
searched directly from the source code directories, to help the
cases where we can build either from in-kernel source libraries or
from the same library shipped as a distro package, as is the case
with libbpf and was the case with libtraceevent.
perf stat:
- Do not delay the workload with --delay, the delay is just for
starting to count the events, to skip noise at workload startup.
- When we have events for each cgroup, the metric should be printed
for each cgroup separately.
$ perf stat -a --for-each-cgroup system.slice,user.slice --metric-only sleep 1
Performance counter stats for 'system wide':
GHz insn per cycle branch-misses of all branches
system.slice 3.792 0.61 3.24%
user.slice 3.661 2.32 0.37%
- Fix printing field separator in CSV metrics output.
- Fix --metric-only --json output.
- Fix summary output in CSV with --metric-only.
- Update event group check for support of uncore event.
perf test:
- Stop requiring a C toolchain in shell tests, instead add a workload
option that has all the previously C snippets built as part of
'perf test -w' that then get used in the 'perf test' shell scripts.
- Add event group test for events in multiple PMUs
- The "kernel lock contention analysis" test should not print
warnings in quiet mode.
- Add attr tests for ARM64's new VG register.
- Fix record test on KVM guests, as using precise flag with the
br_inst_retired.near_call event causes the test fail on KVM guests,
even when the guests have PMU forwarding enabled and the event
itself is supported, so just remove the precise flag from the
event.
- Add mechanism for skipping attr tests on specific kernel versions
where it is known that these checks will fail.
- Skip watchpoint tests if no watchpoints available.
- Add more Intel PT 'perf test' entries: hybrid CPUs, split the
packet decoder into a suite of subtests.
perf script:
- Introduce task analyzer python script, where one first records some events:
Recording can be done in two ways:
$ perf script record tasks-analyzer -- sleep 10
$ perf record -e sched:sched_switch -a -- sleep 10
The script can parse any perf.data files, as long as it has
sched:sched_switch events, other events will be ignored.
The most simple report use case is to just call the script without
arguments.
Runtime is the time the task was running on the CPU, Time Out-In is
the time between the process being scheduled *out* and scheduled
back *in*. So the last time span between two executions:

USB/Thunderbolt driver changes for 6.2-rc1
Here is the large set of USB and Thunderbolt driver changes for 6.2-rc1.
Overall, thanks to the removal of a driver, more lines were removed than
added, a nice change. Highlights include:
- removal of the sisusbvga driver that was not used by anyone anymore
- minor thunderbolt driver changes and tweaks
- chipidea driver updates
- usual set of typec driver features and hardware support added
- musb minor driver fixes
- fotg210 driver fixes, bringing that hardware back from the "dead"
- minor dwc3 driver updates
- addition, and then removal, of a list.h helper function for many USB
and other subsystem drivers, that ended up breaking the build. That
will come back for 6.3-rc1, it missed this merge window.
- usual xhci updates and enhancements
- usb-serial driver updates and support for new devices
- other minor USB driver updates
All of these have been in linux-next for a while with no reported
problems.

- Add the call depth tracking mitigation for Retbleed which has
been long in the making. It is a lighterweight software-only fix for Skylake-based cores where enabling IBRS is a big hammer and causes a significant performance impact. What it basically does is, it aligns all kernel functions to 16 bytes boundary and adds a 16-byte padding before the function, objtool collects all functions' locations and when the mitigation gets applied, it patches a call accounting thunk which is used to track the call depth of the stack at any time. When that call depth reaches a magical, microarchitecture-specific value for the Return Stack Buffer, the code stuffs that RSB and avoids its underflow which could otherwise lead to the Intel variant of Retbleed.

perf stat: Do not delay the workload with --delay
The -D/--delay option is to delay the measure after the program starts.
But the current code goes to sleep before starting the program so the
program is delayed too. This is not the intention, let's fix it.
Before:
$ time sudo ./perf stat -a -e cycles -D 3000 sleep 4
Events disabled
Events enabled
Performance counter stats for 'system wide':
4,326,949,337 cycles
4.007494118 seconds time elapsed
real 0m7.474s
user 0m0.356s
sys 0m0.120s
It ran the workload for 4 seconds and gave the 3 second delay. So it
should skip the first 3 second and measure the last 1 second only. But
as you can see, it delays 3 seconds and ran the workload after that for
4 seconds. So the total time (real) was 7 seconds.
After:
$ time sudo ./perf stat -a -e cycles -D 3000 sleep 4
Events disabled
Events enabled
Performance counter stats for 'system wide':
1,063,551,013 cycles
1.002769510 seconds time elapsed
real 0m4.484s
user 0m0.385s
sys 0m0.086s
The bug was introduced when it changed enablement of system-wide events
with a command line workload. But it should've considered the initial
delay case. The code was reworked since then (in

BPF selftests require CONFIG_FUNCTION_ERROR_INJECTION to work. However,
CONFIG_FUNCTION_ERROR_INJECTION is no longer 'y' by default after recent

bpf_testmod_test_read() is not modifiable
__x64_sys_setdomainname is not sleepable
__x64_sys_getpgid is not sleepable
Fix this by explicitly selecting CONFIG_FUNCTION_ERROR_INJECTION in the

When CONFIG_SMP is not set, the field 'last_wakee' is not available in struct

iommufd for 6.2
iommufd is the user API to control the IOMMU subsystem as it relates to managing IO page tables that point at user space memory. It takes over from drivers/vfio/vfio_iommu_type1.c (aka the VFIO container) which is the VFIO specific interface for a similar idea. We see a broad need for extended features, some being highly IOMMU device specific: - Binding iommu_domain's to PASID/SSID - Userspace IO page tables, for ARM, x86 and S390 - Kernel bypassed invalidation of user page tables - Re-use of the KVM page table in the IOMMU - Dirty page tracking in the IOMMU - Runtime Increase/Decrease of IOPTE size - PRI support with faults resolved in userspace Many of these HW features exist to support VM use cases - for instance the combination of PASID, PRI and Userspace IO Page Tables allows an implementation of DMA Shared Virtual Addressing (vSVA) within a guest. Dirty tracking enables VM live migration with SRIOV devices and PASID support allow creating "scalable IOV" devices, among other things.

perf build: Fix python/perf.so library's name
Since Python 3.3 extensions have a suffix encoding platform and version information. For example, the perf extension was previously perf.so but now maybe perf.cpython-310-x86_64-linux-gnu.so. Compute the extension using Python and then use this in the target name. Doing this avoids the "perf.so" target always being rebuilt.

perf test: Add mechanism for skipping attr tests on kernel versions
The first two version numbers are used since that is where the ABI changes happen, so seems to be the most useful for now. 'Until' is exclusive and 'since' is inclusive so that the same version number can be used to mark a point where the change comes into effect. This allows keeping the tests in a state where new tests will also pass on older kernels if the existence of a new feature isn't explicitly broadcast by the kernel. For example extended user regs are currently discovered by trial and error calls to perf_event_open.

perf script: task-analyzer add csv support
This patch adds the possibility to write the trace and the summary as csv files
to a user specified file. A format as such simplifies further data processing.
This is achieved by having ";" as separators instead of spaces and solely one
header per file.
Additional parameters are being considered, like in the normal usage of the
script. Colors are turned off in the case of a csv output, thus the highlight
option is also being ignored.
Usage:
Write standard task to csv file:
$ perf script report tasks-analyzer --csv <file>
write limited output to csv file in nanoseconds:
$ perf script report tasks-analyzer --csv <file> --ns --limit-to-tasks 1337
Write summary to a csv file:
$ perf script report tasks-analyzer --csv-summary <file>
Write summary to csv file with additional schedule information:
$ perf script report tasks-analyzer --csv-summary <file> --summary-extended
Write both summary and standard task to a csv file:
$ perf script report tasks-analyzer --csv --csv-summary
The following examples illustrate what is possible with the CSV output. The
first command sequence will record all scheduler switch events for 10 seconds,
the task-analyzer calculates task information like runtimes as CSV. A small
python snippet using pandas and matplotlib will visualize the most frequent
task (e.g. kworker/1:1) runtimes - each runtime as a bar in a bar chart:
$ perf record -e sched:sched_switch -a -- sleep 10
$ perf script report tasks-analyzer --ns --csv tasks.csv
$ cat << EOF > /tmp/freq-comm-runtimes-bar.py
import pandas as pd
import matplotlib.pyplot as plt
df = pd.read_csv("tasks.csv", sep=';')
most_freq_comm = df["COMM"].value_counts().idxmax()
most_freq_runtimes = df[df["COMM"]==most_freq_comm]["Runtime"]
plt.title(f"Runtimes for Task {most_freq_comm} in Nanoseconds")
plt.bar(range(len(most_freq_runtimes)), most_freq_runtimes)
plt.show()
$ python3 /tmp/freq-comm-runtimes-bar.py
As a seconds example, the subsequent script generates a pie chart of all
accumulated tasks runtimes for 10 seconds of system recordings:
$ perf record -e sched:sched_switch -a -- sleep 10
$ perf script report tasks-analyzer --csv-summary task-summary.csv
$ cat << EOF > /tmp/accumulated-task-pie.py

perf script: Introduce task analyzer python script
Introduce a new 'perf script' to analyze task scheduling behavior.
During the task analysis, some data is always needed - which goes beyond
the simple time of switching on and off a task (process/thread). This
concerns for example the runtime of a process or the frequency with
which the process was called. This script serves to simplify this
recurring analyze process. It immediately provides the user with helpful
task characteristic information about the tasks runtimes.
Usage:
Recorded can be in two ways:
$ perf script record tasks-analyzer -- sleep 10
$ perf record -e sched:sched_switch -a -- sleep 10
The script can parse all perf.data files, most important: sched:sched_switch
events are mandatory, other events will be ignored.
Most simple report use case is to just call the script without arguments:
$ perf script report tasks-analyzer
Switched-In Switched-Out CPU PID TID Comm Runtime Time Out-In
15576.658891407 15576.659156086 4 2412 2428 gdbus 265 1949
15576.659111320 15576.659455410 0 2412 2412 gnome-shell 344 2267
15576.659491326 15576.659506173 2 74 74 kworker/2:1 15 13145
15576.659506173 15576.659825748 2 2858 2858 gnome-terminal- 320 63263
15576.659871270 15576.659902872 6 20932 20932 kworker/u16:0 32 2314582

15576.659853285 15576.659971052 7 27265 27265 perf 118 5050741
[...]
What is not shown here are the ASCII color sequences. For example, if
the task consists of only one thread, the TID is grayed out.
Runtime is the time the task was running on the CPU, Time Out-In is the
time between the process being scheduled *out* and scheduled back *in*.
So the last time span between two executions. If -1 is printed, then the
task simply ran the first time in the measurements - a Out-In delta
could not be calculated.
In addition to the chronological representation, there is a summary on
task level. This output can be additionally switched on via the
--summary option and provides information such as max, min & average
runtime per process. The maximum runtime is often important for
debugging. The call looks like this:
$ perf script report tasks-analyzer --summary
Summary
Task Information Runtime Information
PID TID Comm Runs Accumulated Mean Median Min Max Max At
14 14 ksoftirqd/0 13 334 26 15 9 127 15571.621211956
15 15 rcu_preempt 133 1778 13 13 2 33 15572.581176024
16 16 migration/0 3 49 16 13 12 24 15571.608915425
20 20 migration/1 3 34 11 13 8 13 15571.639101555
25 25 migration/2 3 32 11 12 9 12 15575.639239896
[...]
Besides these two options, there are a number of other options that change the
output and behavior. This can be queried via --help. Options worth mentioning include:
- filter-tasks - filter out unneeded tasks, --filter-task 1337,/sbin/init
- highlight-tasks - more pleasant focusing, --highlight-tasks 1:red,mutt:yellow
- extended-times - show combinations of elapsed times between schedule in/schedule out
- summary-extended - summary with additional information, like maximum delta time statistics
- rename-comms-by-tids - handy for inexpressive processnames like python, --rename 1337:my-python-app
- ms - show timestamps in milliseconds, nanoseconds is also possible (--ns)
- time-limit - limit the analyzer to a time range, --time-limit 15576.0:15576.1
Script is tested and prime time ready for python2 & python3:
- make PYTHON=python3 prefix=/usr/local install
- make PYTHON=python2 prefix=/usr/local install

perf cs-etm: Print auxtrace info even if OpenCSD isn't linked
Printing the info doesn't have any dependency on OpenCSD, and neither does recording Coresight data. Because it's sometimes useful to look at the info for debugging, it makes sense to be able to see it on the same platform that the recording was made on. So pull the auxtrace info printing parts into a new file that is always compiled into Perf.

perf test: Update event group check for support of uncore event
The event group test checks group creation for combinations of hw, sw

permission to access the counters.
For example, in case of hv_24x7, partition need to have permissions to
access hv_24x7 pmu counters. If not, event_open will fail. Hence add a
sanity check to see if event_open succeeds before proceeding with the
test.

If libtraceevent isn't installed or NO_LIBTRACEEVENT=1 is passed to the build, don't compile in libtraceevent and libtracefs support. This also disables CONFIG_TRACE that controls "perf trace". CONFIG_LIBTRACEEVENT is used to control enablement in Build/Makefiles, HAVE_LIBTRACEEVENT is used in C code.

Building without libtraceevent-devel installed uncovered more build failures: - The python binding tools/perf/util/python.c was assuming that traceevent/parse-events.h was always available, which was the case when we defaulted to using the in-kernel tools/lib/traceevent/ files, now we need to enclose it under ifdef HAVE_LIBTRACEEVENT, just like the other parts of it that deal with tracepoints. - We have to ifdef the rules in the Build files with CONFIG_LIBTRACEEVENT=y to build builtin-trace.c and tools/perf/trace/beauty/ as we only ifdef setting CONFIG_TRACE=y when setting NO_LIBTRACEEVENT=1 in the make command line, not when we don't detect libtraceevent-devel installed in the system. Simplification here to avoid these two ways of disabling builtin-trace.c and not having CONFIG_TRACE=y when libtraceevent-devel isn't installed is the clean way. From Athira: <quote> tools/perf/arch/powerpc/util/Build -perf-y += kvm-stat.o +perf-$(CONFIG_LIBTRACEEVENT) += kvm-stat.o </quote> Then, ditto for arm64 and s390, detected by container cross build tests. - s/390 uses test__checkevent_tracepoint() that is now only available if HAVE_LIBTRACEEVENT is defined, enclose the callsite with ifder HAVE_LIBTRACEEVENT. Also from Athira: <quote> With this change, I could successfully compile in these environment: - Without libtraceevent-devel installed - With libtraceevent-devel installed - With “make NO_LIBTRACEEVENT=1” </quote> Then, finally rename CONFIG_TRACEEVENT to CONFIG_LIBTRACEEVENT for consistency with other libraries detected in tools/perf/.

perf jevents: Parse metrics during conversion
Currently the 'MetricExpr' json value is passed from the json
file to the pmu-events.c. This change introduces an expression
tree that is parsed into. The parsing is done largely by using
operator overloading and python's 'eval' function. Two advantages
in doing this are:
1) Broken metrics fail at compile time rather than relying on
`perf test` to detect. `perf test` remains relevant for checking
event encoding and actual metric use.
2) The conversion to a string from the tree can minimize the metric's
string size, for example, preferring 1e6 over 1000000, avoiding
multiplication by 1 and removing unnecessary whitespace. On x86
this reduces the string size by 2,930bytes (0.07%).
In future changes it would be possible to programmatically
generate the json expressions (a single line of text and so a
pain to write manually) for an architecture using the expression
tree. This could avoid copy-pasting metrics for all architecture
variants.
v4. Doesn't simplify "0*SLOTS" to 0, as the pattern is used to fix
Intel metrics with topdown events.
v3. Avoids generic types on standard types like set that aren't
supported until Python 3.9, fixing an issue with Python 3.6
reported-by John Garry. v3 also fixes minor pylint issues and adds
a call to Simplify on the read expression tree.
v2. Improvements to type information.

In print_counter_aggrdata(), it skips some events that has no aggregate

perf stat: Fix printing field separator in CSV metrics output
In 'perf stat' with CSV output option, number of fields in metrics
output is not matching with number of fields in other event output
lines.
Sample output below after applying patch to fix printing os->prefix.
# ./perf stat -x, --per-socket -a -C 1 ls
S0,1,82.11,msec,cpu-clock,82111626,100.00,1.000,CPUs utilized
S0,1,2,,context-switches,82109314,100.00,24.358,/sec
------
====> S0,1,,,,,,,1.71,stalled cycles per insn
The above command line uses field separator as "," via "-x," option and
per-socket option displays socket value as first field. But here the
last line for "stalled cycles per insn" has more separators. Each csv
output line is expected to have 8 field separators (for the 9 fields),
where as last line has 9 "," in the result. Patch fixes this issue.
The counter stats are displayed by function
"perf_stat__print_shadow_stats" in code "util/stat-shadow.c". While
printing the stats info for "stalled cycles per insn", function
"new_line_csv" is used as new_line callback.
The fields printed in each line contains: "Socket_id,aggr
nr,Avg,unit,event_name,run,enable_percent,ratio,unit"
The metric output prints Socket_id, aggr nr, ratio and unit. It has to
skip through remaining five fields ie,
Avg,unit,event_name,run,enable_percent. The csv line callback uses
"os->nfields" to know the number of fields to skip to match with other
lines.
Currently it is set as:
os.nfields = 3 + aggr_fields[config->aggr_mode] + (counter->cgrp ? 1 : 0);
But in case of aggregation modes, csv_sep already gets printed along
with each field (Function "aggr_printout" in util/stat-display.c). So
aggr_fields can be removed from nfields. And fixed number of fields to
skip has to be "4". This is to skip fields for: "avg, unit, event name,
run, enable_percent"
This needs 4 csv separators. Patch removes aggr_fields
and uses 4 as fixed number of os->nfields to skip.
After the patch:
# ./perf stat -x, --per-socket -a -C 1 ls
S0,1,79.08,msec,cpu-clock,79085956,100.00,1.000,CPUs utilized
S0,1,7,,context-switches,79084176,100.00,88.514,/sec
------
====> S0,1,,,,,,0.81,stalled cycles per insn

This series shold have been in the non-MM tree, my bad. - Naoya Horiguchi improved the interaction between memory poisoning and memory section removal for huge pages. - DAMON cleanups and tuneups from SeongJae Park - Tony Luck fixed the handling of COW faults against poisoned pages. - Peter Xu utilized the PTE marker code for handling swapin errors. - Hugh Dickins reworked compound page mapcount handling, simplifying it and making it more efficient. - Removal of the autonuma savedwrite infrastructure from Nadav Amit and David Hildenbrand. - zram support for multiple compression streams from Sergey Senozhatsky. - David Hildenbrand reworked the GUP code's R/O long-term pinning so that drivers no longer need to use the FOLL_FORCE workaround which didn't work very well anyway. - Mel Gorman altered the page allocator so that local IRQs can remnain enabled during per-cpu page allocations. - Vishal Moola removed the try_to_release_page() wrapper. - Stefan Roesch added some per-BDI sysfs tunables which are used to prevent network block devices from dirtying excessive amounts of pagecache. - David Hildenbrand did some cleanup and repair work on KSM COW breaking. - Nhat Pham and Johannes Weiner have implemented writeback in zswap's zsmalloc backend. - Brian Foster has fixed a longstanding corner-case oddity in file[map]_write_and_wait_range(). - sparse-vmemmap changes for MIPS, LoongArch and NIOS2 from Feiyang Chen. - Shiyang Ruan has done some work on fsdax, to make its reflink mode work better under xfstests. Better, but still not perfect. - Christoph Hellwig has removed the .writepage() method from several filesystems. They only need .writepages(). - Yosry Ahmed wrote a series which fixes the memcg reclaim target beancounting. - David Hildenbrand has fixed some of our MM selftests for 32-bit machines. - Many singleton patches, as usual. -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQTTMBEPP41GrTpTJgfdBJ7gKXxAjgUCY5j6ZwAKCRDdBJ7gKXxA jkDYAP9qNeVqp9iuHjZNTqzMXkfmJPsw2kmy2P+VdzYVuQRcJgEAgoV9d7oMq4ml CodAgiA51qwzId3GRytIo/tfWZSezgA= =d19R -----END PGP SIGNATURE----- Merge tag 'mm-stable-2022-12-13' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Pull MM updates from Andrew Morton: - More userfaultfs work from Peter Xu - Several convert-to-folios series from Sidhartha Kumar and Huang Ying - Some filemap cleanups from Vishal Moola - David Hildenbrand added the ability to selftest anon memory COW handling - Some cpuset simplifications from Liu Shixin - Addition of vmalloc tracing support by Uladzislau Rezki - Some pagecache folioifications and simplifications from Matthew Wilcox - A pagemap cleanup from Kefeng Wang: we have VM_ACCESS_FLAGS, so use it - Miguel Ojeda contributed some cleanups for our use of the __no_sanitize_thread__ gcc keyword.

sound updates for 6.2-rc1
This looks like a relatively calm development cycle; there have been
only few changes in ALSA and ASoC core sides while we get lots of
device-specific fixes and updates as usual. Most of commits are about
ASoC, including Intel SOF/AVS and many device tree updates.
Below are some highlights:
Core:
- Improvement in memalloc helper for fallback allocations
- More cleanups of ASoC DAPM code
ASoC:
- Factoring out of mapping hw_params onto SoundWire configuration
- The ever ongoing overhauls of the Intel DSP code continue, including
support for loading libraries and probes with IPC4 on SOF.
- Support for more sample formats on JZ4740
- Lots of device tree conversions and fixups
- Support for Allwinner D1, a range of AMD and Intel systems, Mediatek
systems with multiple DMICs, Nuvoton NAU8318, NXP fsl_rpmsg and
i.MX93, Qualcomm AudioReach Enable, MFC and SAL, RealTek RT1318 and
Rockchip RK3588
ALSA:
- Addition of PCM kselftest; still minimalistic but can be extended
in future
- Fixes for corner-case XRUNs with USB-audio implicit feedback mode
- Usual device-specific quirk updates for USB- and HD-audio
- FireWire DICE updates
Also, this PR also contains a few cross-tree updates:
- Some OMAP board file updates for removal of relevant OMAP platforms
- A new I2C API update for I2C probe API adaption
- A DRM update for the further hdmi-codec updates

As described by Günther [1], the goal of these patches is to work towards a more complete coverage of file system operations that are restrictable with Landlock. The known set of currently unsupported file system operations in Landlock is described at [2]. Out of the operations listed there, truncate is the only one that modifies file contents, so these patches should make it possible to prevent the direct modification of file contents with Landlock. The new LANDLOCK_ACCESS_FS_TRUNCATE access right covers both the truncate(2) and ftruncate(2) families of syscalls, as well as open(2) with the O_TRUNC flag. This includes usages of creat() in the case where existing regular files are overwritten. Additionally, this introduces a new Landlock security blob associated with opened files, to track the available Landlock access rights at the time of opening the file. This is in line with Unix's general approach of checking the read and write permissions during open(), and associating this previously checked authorization with the opened file. An ongoing patch documents this use case [3]. In order to treat truncate(2) and ftruncate(2) calls differently in an LSM hook, we split apart the existing security_path_truncate hook into security_path_truncate (for truncation by path) and security_file_truncate (for truncation of previously opened files)" Link: https://lore.kernel.org/r/20221018182216.301684-1-gnoack3000@gmail.com [1] Link: https://www.kernel.org/doc/html/v6.1/userspace-api/landlock.html#filesystem-flags [2] Link: https://lore.kernel.org/r/20221209193813.972012-1-mic@digikod.net [3] * tag 'landlock-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mic/linux: samples/landlock: Document best-effort approach for LANDLOCK_ACCESS_FS_REFER landlock: Document Landlock's file truncation support samples/landlock: Extend sample tool to support LANDLOCK_ACCESS_FS_TRUNCATE selftests/landlock: Test ftruncate on FDs created by memfd_create(2) selftests/landlock: Test FD passing from restricted to unrestricted processes selftests/landlock: Locally define __maybe_unused selftests/landlock: Test open() and ftruncate() in multiple scenarios selftests/landlock: Test file truncation support landlock: Support file truncation landlock: Document init_layer_masks() helper landlock: Refactor check_access_path_dual() into is_access_to_paths_allowed() security: Create file_truncate hook from path_truncate hook |

Pull random number generator updates from Jason Donenfeld:
- Replace prandom_u32_max() and various open-coded variants of it,
there is now a new family of functions that uses fast rejection
sampling to choose properly uniformly random numbers within an
interval:
get_random_u32_below(ceil) - [0, ceil)
get_random_u32_above(floor) - (floor, U32_MAX]
get_random_u32_inclusive(floor, ceil) - [floor, ceil]
Coccinelle was used to convert all current users of
prandom_u32_max(), as well as many open-coded patterns, resulting in
improvements throughout the tree.
I'll have a "late" 6.1-rc1 pull for you that removes the now unused
prandom_u32_max() function, just in case any other trees add a new
use case of it that needs to converted. According to linux-next,
there may be two trivial cases of prandom_u32_max() reintroductions
that are fixable with a 's/.../.../'. So I'll have for you a final
conversion patch doing that alongside the removal patch during the
second week.
This is a treewide change that touches many files throughout.
- More consistent use of get_random_canary().
- Updates to comments, documentation, tests, headers, and
simplification in configuration.
- The arch_get_random*_early() abstraction was only used by arm64 and
wasn't entirely useful, so this has been replaced by code that works
in all relevant contexts.
- The kernel will use and manage random seeds in non-volatile EFI
variables, refreshing a variable with a fresh seed when the RNG is
initialized. The RNG GUID namespace is then hidden from efivarfs to
prevent accidental leakage.
These changes are split into random.c infrastructure code used in the
EFI subsystem, in this pull request, and related support inside of
EFISTUB, in Ard's EFI tree. These are co-dependent for full
functionality, but the order of merging doesn't matter.
- Part of the infrastructure added for the EFI support is also used for
an improvement to the way vsprintf initializes its siphash key,
replacing an sleep loop wart.
- The hardware RNG framework now always calls its correct random.c
input function, add_hwgenerator_randomness(), rather than sometimes
going through helpers better suited for other cases.
- The add_latent_entropy() function has long been called from the fork
handler, but is a no-op when the latent entropy gcc plugin isn't
used, which is fine for the purposes of latent entropy.
But it was missing out on the cycle counter that was also being mixed
in beside the latent entropy variable. So now, if the latent entropy
gcc plugin isn't enabled, add_latent_entropy() will expand to a call
to add_device_randomness(NULL, 0), which adds a cycle counter,
without the absent latent entropy variable.
- The RNG is now reseeded from a delayed worker, rather than on demand
when used. Always running from a worker allows it to make use of the
CPU RNG on platforms like S390x, whose instructions are too slow to
do so from interrupts. It also has the effect of adding in new inputs
more frequently with more regularity, amounting to a long term
transcript of random values. Plus, it helps a bit with the upcoming
vDSO implementation (which isn't yet ready for 6.2).
- The jitter entropy algorithm now tries to execute on many different
CPUs, round-robining, in hopes of hitting even more memory latencies
and other unpredictable effects. It also will mix in a cycle counter
when the entropy timer fires, in addition to being mixed in from the
main loop, to account more explicitly for fluctuations in that timer
firing. And the state it touches is now kept within the same cache
line, so that it's assured that the different execution contexts will
cause latencies.

Pablo Neira Ayuso says:
====================
Netfilter/IPVS updates for net-next
1) Incorrect error check in nft_expr_inner_parse(), from Dan Carpenter.
2) Add DATA_SENT state to SCTP connection tracking helper, from
Sriram Yagnaraman.
3) Consolidate nf_confirm for ipv4 and ipv6, from Florian Westphal.
4) Add bitmask support for ipset, from Vishwanath Pai.
5) Handle icmpv6 redirects as RELATED, from Florian Westphal.
6) Add WARN_ON_ONCE() to impossible case in flowtable datapath,
from Li Qiong.
7) A large batch of IPVS updates to replace timer-based estimators by
kthreads to scale up wrt. CPUs and workload (millions of estimators).
Julian Anastasov says:
This patchset implements stats estimation in kthread context.
It replaces the code that runs on single CPU in timer context every 2
seconds and causing latency splats as shown in reports [1], [2], [3].
The solution targets setups with thousands of IPVS services,
destinations and multi-CPU boxes.
Spread the estimation on multiple (configured) CPUs and multiple
time slots (timer ticks) by using multiple chains organized under RCU
rules. When stats are not needed, it is recommended to use
run_estimation=0 as already implemented before this change.
RCU Locking:
- As stats are now RCU-locked, tot_stats, svc and dest which
hold estimator structures are now always freed from RCU
callback. This ensures RCU grace period after the
ip_vs_stop_estimator() call.
Kthread data:
- every kthread works over its own data structure and all
such structures are attached to array. For now we limit
kthreads depending on the number of CPUs.
- even while there can be a kthread structure, its task
may not be running, eg. before first service is added or
while the sysctl var is set to an empty cpulist or
when run_estimation is set to 0 to disable the estimation.
- the allocated kthread context may grow from 1 to 50
allocated structures for timer ticks which saves memory for
setups with small number of estimators
- a task and its structure may be released if all
estimators are unlinked from its chains, leaving the
slot in the array empty
- every kthread data structure allows limited number
of estimators. Kthread 0 is also used to initially
calculate the max number of estimators to allow in every
chain considering a sub-100 microsecond cond_resched
rate. This number can be from 1 to hundreds.
- kthread 0 has an additional job of optimizing the
adding of estimators: they are first added in
temp list (est_temp_list) and later kthread 0
distributes them to other kthreads. The optimization
is based on the fact that newly added estimator
should be estimated after 2 seconds, so we have the
time to offload the adding to chain from controlling
process to kthread 0.
- to add new estimators we use the last added kthread
context (est_add_ktid). The new estimators are linked to
the chains just before the estimated one, based on add_row.
This ensures their estimation will start after 2 seconds.
If estimators are added in bursts, common case if all
services and dests are initially configured, we may
spread the estimators to more chains and as result,
reducing the initial delay below 2 seconds.
Many thanks to Jiri Wiesner for his valuable comments
and for spending a lot of time reviewing and testing
the changes on different platforms with 48-256 CPUs and
1-8 NUMA nodes under different cpufreq governors.
The new IPVS estimators do not use workqueue infrastructure
because:
- The estimation can take long time when using multiple IPVS rules (eg.
millions estimator structures) and especially when box has multiple
CPUs due to the for_each_possible_cpu usage that expects packets from
any CPU. With est_nice sysctl we have more control how to prioritize the
estimation kthreads compared to other processes/kthreads that have
latency requirements (such as servers). As a benefit, we can see these
kthreads in top and decide if we will need some further control to limit
their CPU usage (max number of structure to estimate per kthread).
- with kthreads we run code that is read-mostly, no write/lock
operations to process the estimators in 2-second intervals.
- work items are one-shot: as estimators are processed every
2 seconds, they need to be re-added every time. This again
loads the timers (add_timer) if we use delayed works, as there are
no kthreads to do the timings.

Pull cxl updates from Dan Williams:
"Compute Express Link (CXL) updates for 6.2.
While it may seem backwards, the CXL update this time around includes
some focus on CXL 1.x enabling where the work to date had been with
CXL 2.0 (VH topologies) in mind.
First generation CXL can mostly be supported via BIOS, similar to DDR,
however it became clear there are use cases for OS native CXL error
handling and some CXL 3.0 endpoint features can be deployed on CXL 1.x
hosts (Restricted CXL Host (RCH) topologies). So, this update brings
RCH topologies into the Linux CXL device model.
In support of the ongoing CXL 2.0+ enabling two new core kernel
facilities are added.
One is the ability for the kernel to flag collisions between userspace
access to PCI configuration registers and kernel accesses. This is
brought on by the PCIe Data-Object-Exchange (DOE) facility, a hardware
mailbox over config-cycles.
The other is a cpu_cache_invalidate_memregion() API that maps to
wbinvd_on_all_cpus() on x86. To prevent abuse it is disabled in guest
VMs and architectures that do not support it yet. The CXL paths that
need it, dynamic memory region creation and security commands (erase /
unlock), are disabled when it is not present.
As for the CXL 2.0+ this cycle the subsystem gains support Persistent
Memory Security commands, error handling in response to PCIe AER
notifications, and support for the "XOR" host bridge interleave
algorithm.
Summary:
- Add the cpu_cache_invalidate_memregion() API for cache flushing in
response to physical memory reconfiguration, or memory-side data
invalidation from operations like secure erase or memory-device
unlock.
- Add a facility for the kernel to warn about collisions between

kunit: tool: make parser preserve whitespace when printing test log
Currently, kunit_parser.py is stripping all leading whitespace to make parsing easier. But this means we can't accurately show kernel output for failing tests or when the kernel crashes. Embarassingly, this affects even KUnit's own output, e.g. [13:40:46] Expected 2 + 1 == 2, but [13:40:46] 2 + 1 == 3 (0x3) [13:40:46] not ok 1 example_simple_test [13:40:46] [FAILED] example_simple_test After this change, here's what the output in context would look like [13:40:46] =================== example (4 subtests) =================== [13:40:46] # example_simple_test: initializing [13:40:46] # example_simple_test: EXPECTATION FAILED at lib/kunit/kunit-example-test.c:29 [13:40:46] Expected 2 + 1 == 2, but [13:40:46] 2 + 1 == 3 (0x3) [13:40:46] [FAILED] example_simple_test [13:40:46] [SKIPPED] example_skip_test [13:40:46] [SKIPPED] example_mark_skipped_test [13:40:46] [PASSED] example_all_expect_macros_test [13:40:46] # example: initializing suite [13:40:46] # example: pass:1 fail:1 skip:2 total:4 [13:40:46] # Totals: pass:1 fail:1 skip:2 total:4 [13:40:46] ===================== [FAILED] example ===================== This example shows one minor cosmetic defect this approach has. The test counts lines prevent us from dedenting the suite-level output. But at the same time, any form of non-KUnit output would do the same unless it happened to be indented as well.

kunit: tool: don't include KTAP headers and the like in the test log
We print the "test log" on failure. This is meant to be all the kernel output that happened during the test. But we also include the special KTAP lines in it, which are often redundant. E.g. we include the "not ok" line in the log, right before we print that the test case failed...

kunit: tool: make --json do nothing if --raw_ouput is set
When --raw_output is set (to any value), we don't actually parse the test results. So asking to print the test results as json doesn't make sense. We internally create a fake test with one passing subtest, so --json would actually print out something misleading. This patch: * Rewords the flag descriptions so hopefully this is more obvious. * Also updates --raw_output's description to note the default behavior is to print out only "KUnit" results (actually any KTAP results) * also renames and refactors some related logic for clarity (e.g. test_result => test, it's a kunit_parser.Test object). Notably, this patch does not make it an error to specify --json and --raw_output together. This is an edge case, but I know of at least one wrapper around kunit.py that always sets --json. You'd never be able to use --raw_output with that wrapper.

kunit: tool: tweak error message when no KTAP found
We currently tell people we "couldn't find any KTAP output" with no indication as to what this might mean. After this patch, we get: $ ./tools/testing/kunit/kunit.py parse /dev/null ============================================================ [ERROR] Test: <missing>: Could not find any KTAP output. Did any KUnit tests run? ============================================================ Testing complete.

kunit: tool: make TestCounts a dataclass
Since we're using Python 3.7+, we can use dataclasses to tersen the code. It also lets us create pre-populated TestCounts() objects and compare them in our unit test.

Merge remote-tracking branch 'kvm/queue' into HEAD
x86 Xen-for-KVM: * Allow the Xen runstate information to cross a page boundary * Allow XEN_RUNSTATE_UPDATE flag behaviour to be configured * add support for 32-bit guests in SCHEDOP_poll x86 fixes: * One-off fixes for various emulation flows (SGX, VMXON, NRIPS=0). * Reinstate IBPB on emulated VM-Exit that was incorrectly dropped a few years back when eliminating unnecessary barriers when switching between vmcs01 and vmcs02. * Clean up the MSR filter docs. * Clean up vmread_error_trampoline() to make it more obvious that params must be passed on the stack, even for x86-64. * Let userspace set all supported bits in MSR_IA32_FEAT_CTL irrespective of the current guest CPUID. * Fudge around a race with TSC refinement that results in KVM incorrectly thinking a guest needs TSC scaling when running on a CPU with a constant TSC, but no hardware-enumerated TSC frequency. * Advertise (on AMD) that the SMM_CTL MSR is not supported * Remove unnecessary exports Selftests: * Fix an inverted check in the access tracking perf test, and restore support for asserting that there aren't too many idle pages when running on bare metal. * Fix an ordering issue in the AMX test introduced by recent conversions to use kvm_cpu_has(), and harden the code to guard against similar bugs in the future. Anything that tiggers caching of KVM's supported CPUID, kvm_cpu_has() in this case, effectively hides opt-in XSAVE features if the caching occurs before the test opts in via prctl(). * Fix build errors that occur in certain setups (unsure exactly what is unique about the problematic setup) due to glibc overriding static_assert() to a variant that requires a custom message. * Introduce actual atomics for clear/set_bit() in selftests Documentation: * Remove deleted ioctls from documentation * Various fixes |

arm64 updates for 6.2
ACPI:
* Enable FPDT support for boot-time profiling
* Fix CPU PMU probing to work better with PREEMPT_RT
* Update SMMUv3 MSI DeviceID parsing to latest IORT spec
* APMT support for probing Arm CoreSight PMU devices
CPU features:
* Advertise new SVE instructions (v2.1)
* Advertise range prefetch instruction
* Advertise CSSC ("Common Short Sequence Compression") scalar
instructions, adding things like min, max, abs, popcount
* Enable DIT (Data Independent Timing) when running in the kernel
* More conversion of system register fields over to the generated
header
CPU misfeatures:
* Workaround for Cortex-A715 erratum #2645198
Dynamic SCS:
* Support for dynamic shadow call stacks to allow switching at
runtime between Clang's SCS implementation and the CPU's
pointer authentication feature when it is supported (complete
with scary DWARF parser!)
Tracing and debug:
* Remove static ftrace in favour of, err, dynamic ftrace!
* Seperate 'struct ftrace_regs' from 'struct pt_regs' in core
ftrace and existing arch code
* Introduce and implement FTRACE_WITH_ARGS on arm64 to replace
the old FTRACE_WITH_REGS
* Extend 'crashkernel=' parameter with default value and fallback
to placement above 4G physical if initial (low) allocation
fails
SVE:
* Optimisation to avoid disabling SVE unconditionally on syscall
entry and just zeroing the non-shared state on return instead
Exceptions:
* Rework of undefined instruction handling to avoid serialisation
on global lock (this includes emulation of user accesses to the
ID registers)
Perf and PMU:
* Support for TLP filters in Hisilicon's PCIe PMU device
* Support for the DDR PMU present in Amlogic Meson G12 SoCs
* Support for the terribly-named "CoreSight PMU" architecture
from Arm (and Nvidia's implementation of said architecture)
Misc:
* Tighten up our boot protocol for systems with memory above
52 bits physical
* Const-ify static keys to satisty jump label asm constraints
* Trivial FFA driver cleanups in preparation for v1.1 support
* Export the kernel_neon_* APIs as GPL symbols
* Harden our instruction generation routines against
instrumentation
* A bunch of robustness improvements to our arch-specific selftests
* Minor cleanups and fixes all over (kbuild, kprobes, kfence, PMU, ...)
