count_result() does not always reset ret=0 which means the value can spill
into the next test result.
Fix by explicitly setting it to zero between tests.

If the kernel exposes a new perf_event_attr field in a format attr, perf
will return an error stating the specified PMU can't be found. For
example, a format attr with 'config3:0-63' causes an error as config3 is
unknown to perf. This causes a compatibility issue between a newer
kernel with older perf tool.
Before this change with a kernel adding 'config3' I get:
$ perf record -e arm_spe// -- true
event syntax error: 'arm_spe//'
\___ Cannot find PMU `arm_spe'. Missing kernel support?
Run 'perf list' for a list of valid events
Usage: perf record [<options>] [<command>]
or: perf record [<options>] -- <command> [<options>]
-e, --event <event> event selector. use 'perf list' to list
available events
After this change, I get:
$ perf record -e arm_spe// -- true
WARNING: 'arm_spe_0' format 'inv_event_filter' requires 'perf_event_attr::config3' which is not supported by this version of perf!
[ perf record: Woken up 2 times to write data ]
[ perf record: Captured and wrote 0.091 MB perf.data ]
To support unknown configN formats, rework the YACC implementation to
pass any config[0-9]+ format to perf_pmu__new_format() to handle with a
warning.

The -C/--cpu option was maily for report but it also affected record as

Check if this option is set for record, and pass it to the actual perf
record.

This test commonly fails on Arm Juno because the instruction interval
is large enough to miss generating any samples for Perf in system-wide
mode.
Fix this by lowering the interval until a comfortable number of Perf
instructions are generated. The test is still quick to run because only
a small amount of trace is gathered.

In commit 1bfe26fb0827 ("bpf: Add verifier support for custom callback

helpers to explicitly specify the range of values that can be returned.
bpf_user_ringbuf_drain() was merged after this in commit 205715673844
("bpf: Add bpf_user_ringbuf_drain() helper"), and this change in default
behavior was missed. This patch updates the BPF_MAP_TYPE_USER_RINGBUF
selftests to also return 1 from a bpf_user_ringbuf_drain() callback so
as to properly test this going forward.

there'll be some clue to start with.

- "perf lock" improvements:

just the top 5 contended locks.
- Add -q/--quiet option to suppress header and debug messages.
- Add a 'perf test' kernel lock contention entry to test 'perf lock'.
- "perf lock contention" improvements:
- Ask BPF's bpf_get_stackid() to skip some callchain entries.
The ones closer to the tooling are bpf related and not that interesting, the
ones calling the locking function are the ones we're interested in, example
of a full, unskipped callstack:
- Allow changing the callstack depth and number of entries to skip.

0xffffffffbb8409ee tick_irq_enter+0x9e
- Show full callstack in verbose mode (-v option), sometimes this is desirable
instead of showing just one callstack entry.
- Allow multiple time ranges in 'perf record --delay' to help in reducing the
amount of data collected from hardware tracing (Intel PT, etc) when there is
a rough idea of periods of time where events of interest take time.
- Add Intel PT to record only decoder debug messages when error happens.
- Improve layout of Intel PT man page.
- Add new branch types: alignment, data and inst faults and arch specific ones,
such as fiq, debug_halt, debug_exit, debug_inst and debug_data on arm64.
Kernel enablement went thru the tip tree.
- Fix 'perf probe' error log check in 'perf test' when no debuginfo is
available.
- Fix 'perf stat' aggregation mode logic, it should be looking at the CPU
not at the core number.
- Fix flags parsing in 'perf trace' filters.
- Introduce compact encoding of CPU range encoding on perf.data, to avoid
having a bitmap with all the CPUs.
- Improvements to the 'perf stat' metrics, including adding "core_wide", and
computing "smt" from the CPU topology.
- Add support to the new PERF_FORMAT_LOST perf_event_attr.read_format, that allows
tooling to ask for the precise number of lost samples for a given event.
- Add 'addr' sort key to see just the address of sampled instructions:
$ perf record -o- true | perf report -i- -s addr

perf annotate: Toggle full address <-> offset display
- Add 'f' hotkey to the 'perf annotate' TUI interface when in 'disassembler output'
mode ('o' hotkey) to toggle showing full virtual address or just the offset.
- Cache DSO build-ids when synthesizing PERF_RECORD_MMAP records for pre-existing threads,
at the start of a 'perf record' session, speeding up that record startup phase.
- Add a command line option to specify build ids in 'perf inject'.
- Update JSON event files for the Intel alderlake, broadwell, broadwellde,
broadwellx, cascadelakex, haswell, haswellx, icelake, icelakex, ivybridge,
ivytown, jaketown, sandybridge, sapphirerapids, skylake, skylakex, and
tigerlake processors.
- Update vendor JSON event files for the ARM Neoverse V1 and E1 platforms.
- Add a 'perf test' entry for 'perf mem' where a struct has false sharing and
this gets detected in the 'perf mem' output, tested with Intel, AMD and ARM64
systems.
- Add a 'perf test' entry to test the resolution of java symbols, where an
output like this is expected:
8.18% jshell jitted-50116-29.so [.] Interpreter
0.75% Thread-1 jitted-83602-1670.so [.] jdk.internal.jimage.BasicImageReader.getString(int)
- Add tests for the ARM64 CoreSight hardware tracing feature, with specially
crafted pureloop, memcpy, thread loop and unroll tread that then gets
traced and the output compared with expected output.
Documentation explaining it is also included.
- Add per thread Intel PT 'perf test' entry to check that PERF_RECORD_TEXT_POKE events
are recorded per CPU, resulting in a mixture of per thread and per CPU events and mmaps,
verify that this gets all recorded correctly.
- Introduce pthread mutex wrappers to allow for building with clang's
-Wthread-safety, i.e. using the "guarded_by" "pt_guarded_by" "lockable",
"exclusive_lock_function", "exclusive_trylock_function",
"exclusive_locks_required", and "no_thread_safety_analysis" compiler function
attributes.
- Fix empty version number when building outside of a git repo.
- Improve feature detection display when multiple versions of a feature are present, such
as for binutils libbfd, that has a mix of possible ways to detect according to the
Linux distribution.
Previously in some cases we had:
Auto-detecting system features
<SNIP>
... libbfd: [ on ]
... libbfd-liberty: [ on ]
... libbfd-liberty-z: [ on ]
<SNIP>
Now for this case we show just the main feature:
Auto-detecting system features
<SNIP>
... libbfd: [ on ]
<SNIP>
- Remove some unused structs, variables, macros, function prototypes and
includes from various places.

- Fix 'perf probe' error log check in 'perf test' when no debuginfo is
available.
- Fix 'perf stat' aggregation mode logic, it should be looking at the
CPU not at the core number.
- Fix flags parsing in 'perf trace' filters.
- Introduce compact encoding of CPU range encoding on perf.data, to
avoid having a bitmap with all the CPUs.
- Improvements to the 'perf stat' metrics, including adding
"core_wide", and computing "smt" from the CPU topology.
- Add support to the new PERF_FORMAT_LOST perf_event_attr.read_format,
that allows tooling to ask for the precise number of lost samples for
a given event.
- Add 'addr' sort key to see just the address of sampled instructions:
$ perf record -o- true | perf report -i- -s addr
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.000 MB - ]
# Samples: 12 of event 'cycles:u'
# Event count (approx.): 252512
#
# Overhead Address
# ........ ..................
42.96% 0x7f96f08443d7
29.55% 0x7f96f0859b50
14.76% 0x7f96f0852e02
8.30% 0x7f96f0855028
4.43% 0xffffffff8de01087
perf annotate: Toggle full address <-> offset display
- Add 'f' hotkey to the 'perf annotate' TUI interface when in
'disassembler output' mode ('o' hotkey) to toggle showing full
virtual address or just the offset.
- Cache DSO build-ids when synthesizing PERF_RECORD_MMAP records for
pre-existing threads, at the start of a 'perf record' session,
speeding up that record startup phase.
- Add a command line option to specify build ids in 'perf inject'.
- Update JSON event files for the Intel alderlake, broadwell,
broadwellde, broadwellx, cascadelakex, haswell, haswellx, icelake,
icelakex, ivybridge, ivytown, jaketown, sandybridge, sapphirerapids,
skylake, skylakex, and tigerlake processors.
- Update vendor JSON event files for the ARM Neoverse V1 and E1
platforms.
- Add a 'perf test' entry for 'perf mem' where a struct has false
sharing and this gets detected in the 'perf mem' output, tested with
Intel, AMD and ARM64 systems.
- Add a 'perf test' entry to test the resolution of java symbols, where
an output like this is expected:
8.18% jshell jitted-50116-29.so [.] Interpreter
0.75% Thread-1 jitted-83602-1670.so [.] jdk.internal.jimage.BasicImageReader.getString(int)
- Add tests for the ARM64 CoreSight hardware tracing feature, with
specially crafted pureloop, memcpy, thread loop and unroll tread that
then gets traced and the output compared with expected output.
Documentation explaining it is also included.
- Add per thread Intel PT 'perf test' entry to check that
PERF_RECORD_TEXT_POKE events are recorded per CPU, resulting in a
mixture of per thread and per CPU events and mmaps, verify that this
gets all recorded correctly.
- Introduce pthread mutex wrappers to allow for building with clang's
-Wthread-safety, i.e. using the "guarded_by" "pt_guarded_by"
"lockable", "exclusive_lock_function", "exclusive_trylock_function",
"exclusive_locks_required", and "no_thread_safety_analysis" compiler
function attributes.
- Fix empty version number when building outside of a git repo.
- Improve feature detection display when multiple versions of a feature
are present, such as for binutils libbfd, that has a mix of possible
ways to detect according to the Linux distribution.
Previously in some cases we had:
Auto-detecting system features
<SNIP>
... libbfd: [ on ]
... libbfd-liberty: [ on ]
... libbfd-liberty-z: [ on ]
<SNIP>
Now for this case we show just the main feature:
Auto-detecting system features
<SNIP>
... libbfd: [ on ]
<SNIP>
- Remove some unused structs, variables, macros, function prototypes
and includes from various places.

From me:
cpumask: cleanup nr_cpu_ids vs nr_cpumask_bits mess
This series cleans that mess and adds new config FORCE_NR_CPUS that
allows to optimize cpumask subsystem if the number of CPUs is known
at compile-time.
From me:
lib: optimize find_bit() functions
Reworks find_bit() functions based on new FIND_{FIRST,NEXT}_BIT() macros.
From me:

Adds find_nth_bit(), which is ~70 times faster than bitcounting with
for_each() loop:
for_each_set_bit(bit, mask, size)

Also adds bitmap_weight_and() to let people replace this pattern:

Minor changes:
- Added Mark Rutland as FTRACE reviewer
- Updated user_events to make it on its way to remove the BROKEN tag.
The changes should now be acceptable but will run it through

- Added filtering to eprobes
- Added a delta time to the benchmark trace event
- Have the histogram and filter callbacks called via a switch

Fixes splice never moving forward.
- Fix inverted compare that made the "shortest" ring buffer
wait queue actually the longest.
- Fix a race in the ring buffer between resetting a page when
a writer goes to another page, and the reader.
- Fix ftrace accounting bug when function hooks are added at

- Fix possible recursive locks in osnoise tracer
- Fix recursive locking direct functions

- Fix race between fork and livepatch transition revert
- Add sysfs entry that shows "patched" state for each object (module)
that can be livepatched by the given livepatch
- Some clean up

livepatch: add sysfs entry "patched" for each klp_object

livepatch: fix race between fork and KLP transition
* cpuset now support isolated cpus.partition type, which will enable dynamic
CPU isolation.
* pids.peak added to remember the max number of pids used.
* Holes in cgroup namespace plugged.
* Internal cleanups.
Note that for-6.1-fixes was pulled into for-6.1 twice. Both were for
follow-up cleanups and each merge commit has details.
Also, 8a693f7766f9 ("cgroup: Remove CFTYPE_PRESSURE") removes the flag used
by PSI changes in the tip tree and the merged result won't compile due to
the missing flag. Simply removing the struct init lines specifying the flag
is the correct resolution. linux-next already contains the correct fix:

- Remove the "ANNOTATE_NOENDBR on ENDBR" warning: it's not
really useful and only found a non-bug false positive so far.
- Properly decode LOOP/LOOPE/LOOPNE, which were missing from
the x86 decoder. Because these instructions are rather
ineffective, they never showed up in compiler output,
but they are simple enough to support, so add them for
completeness.
- A bit more cross-arch preparatory work.

__kvm_test_create_device() and caused the test failure on my D05 (which

am sending out early due to me travelling next week. There is a
lone mm patch for which Andrew gave an informal ack at
https://lore.kernel.org/linux-mm/20220817102500.440c6d0a3fce296fdf91bea6@linux-foundation.org.
I will send the bulk of ARM work, as well as other
architectures, at the end of next week.
ARM:
* Account stage2 page table allocations in memory stats.
x86:
* Account EPT/NPT arm64 page table allocations in memory stats.
* Tracepoint cleanups/fixes for nested VM-Enter and emulated MSR accesses.
* Drop eVMCS controls filtering for KVM on Hyper-V, all known versions of
Hyper-V now support eVMCS fields associated with features that are
enumerated to the guest.
* Use KVM's sanitized VMCS config as the basis for the values of nested VMX
capabilities MSRs.
* A myriad event/exception fixes and cleanups. Most notably, pending
exceptions morph into VM-Exits earlier, as soon as the exception is
queued, instead of waiting until the next vmentry. This fixed
a longstanding issue where the exceptions would incorrecly become
double-faults instead of triggering a vmexit; the common case of
page-fault vmexits had a special workaround, but now it's fixed
for good.
* A handful of fixes for memory leaks in error paths.
* Cleanups for VMREAD trampoline and VMX's VM-Exit assembly flow.
* Never write to memory from non-sleepable kvm_vcpu_check_block()
* Selftests refinements and cleanups.
* Misc typo cleanups.
Generic:
* remove KVM_REQ_UNHALT

When running a RISC-V test kernel under QEMU, we need an OpenSBI BIOS
file. In the original QEMU support patchset, kunit_tool would optionally
download this file from GitHub if it didn't exist, using wget.
These days, it can usually be found in the distro's qemu-system-riscv
package, and is located in /usr/share/qemu on all the distros I tried
(Debian, Arch, OpenSUSE). Use this file, and thereby don't do any
downloading in kunit_tool.
In addition, we used to shell out to whatever 'wget' was in the path,
which could have potentially been used to trick the developer into
running another binary. By not using wget at all, we nicely sidestep
this issue.

Pull io_uring updates from Jens Axboe:
- Add supported for more directly managed task_work running.
This is beneficial for real world applications that end up issuing
lots of system calls as part of handling work. Normal task_work will
always execute as we transition in and out of the kernel, even for
"unrelated" system calls. It's more efficient to defer the handling
of io_uring's deferred work until the application wants it to be run,
generally in batches.
As part of ongoing work to write an io_uring network backend for
Thrift, this has been shown to greatly improve performance. (Dylan)
- Add IOPOLL support for passthrough (Kanchan)
- Improvements and fixes to the send zero-copy support (Pavel)
- Partial IO handling fixes (Pavel)
- CQE ordering fixes around CQ ring overflow (Pavel)
- Support sendto() for non-zc as well (Pavel)
- Support sendmsg for zerocopy (Pavel)

This KUnit update for Linux 6.1-rc1 consists of several documentation
fixes, UML related cleanups, and a feature to enable/disable KUnit
tests. This update includes the following change to
- rename all_test_uml.config, use it for --alltests
Note: if anyone was using all_tests_uml.config, this change breaks them.
This change simplifies the usage and eliminates the need to type:
--kunitconfig=tools/testing/kunit/configs/all_tests_uml.config.
A simple workaround to create a symlink to the new name can solve the
problem for anyone using all_tests_uml.config.
all_tests_uml.config should work across ~all architectures.

other arch with different names, for ex, it's called MAB (Miss Address
