perf tools changes for v6.1: 2nd batch
- Use BPF CO-RE (Compile Once, Run Everywhere) to support old kernels
when using bperf (perf BPF based counters) with cgroups.
- Support HiSilicon PCIe Performance Monitoring Unit (PMU), that
monitors bandwidth, latency, bus utilization and buffer occupancy.
Documented in Documentation/admin-guide/perf/hisi-pcie-pmu.rst.
- User space tasks can migrate between CPUs, so when tracing selected
CPUs, system-wide sideband is still needed, fix it in the setup of
Intel PT on hybrid systems.
- Fix metricgroups title message in 'perf list', it should state that
the metrics groups are to be used with the '-M' option, not '-e'.
- Sync the msr-index.h copy with the kernel sources, adding support
for using "AMD64_TSC_RATIO" in filter expressions in 'perf trace' as
well as decoding it when printing the MSR tracepoint arguments.
- Fix program header size and alignment when generating a JIT ELF
in 'perf inject'.
- Add multiple new Intel PT 'perf test' entries, including a jitdump one.
- Fix the 'perf test' entries for 'perf stat' CSV and JSON output when
running on PowerPC due to an invalid topology number in that arch.
- Fix the 'perf test' for arm_coresight failures on the ARM Juno system.
- Fix the 'perf test' attr entry for PERF_FORMAT_LOST, adding this option
to the or expression expected in the intercepted perf_event_open() syscall.
- Add missing condition flags ('hs', 'lo', 'vc', 'vs') for arm64 in the 'perf
annotate' asm parser.
- Fix 'perf mem record -C' option processing, it was being chopped up
when preparing the underlying 'perf record -e mem-events' and thus being
ignored, requiring using '-- -C CPUs' as a workaround.
- Improvements and tidy ups for 'perf test' shell infra.
- Fix Intel PT information printing segfault in uClibc, where a NULL
format was being passed to fprintf.

perf auxtrace arm64: Add support for HiSilicon PCIe Tune and Trace device driver

perf tests stat+json_output: Include sanity check for topology
Testcase stat+json_output.sh fails in powerpc:
86: perf stat JSON output linter : FAILED!
The testcase "stat+json_output.sh" verifies perf stat JSON output. The
test covers aggregation modes like per-socket, per-core, per-die, -A
(no_aggr mode) along with few other tests. It counts expected fields for
various commands. For example say -A (i.e, AGGR_NONE mode), expects 7
fields in the output having "CPU" as first field. Same way, for
per-socket, it expects the first field in result to point to socket id.
The testcases compares the result with expected count.
The values for socket, die, core and cpu are fetched from topology
directory:
/sys/devices/system/cpu/cpu*/topology.
For example, socket value is fetched from "physical_package_id" file of
topology directory. (cpu__get_topology_int() in util/cpumap.c)
If a platform fails to fetch the topology information, values will be
set to -1. For example, incase of pSeries platform of powerpc, value for
"physical_package_id" is restricted and not exposed. So, -1 will be
assigned.
Perf code has a checks for valid cpu id in "aggr_printout"
(stat-display.c), which displays the fields. So, in cases where topology
values not exposed, first field of the output displaying will be empty.
This cause the testcase to fail, as it counts number of fields in the
output.
Incase of -A (AGGR_NONE mode,), testcase expects 7 fields in the output,
becos of -1 value obtained from topology files for some, only 6 fields
are printed. Hence a testcase failure reported due to mismatch in number
of fields in the output.
Patch here adds a sanity check in the testcase for topology. Check will
help to skip the test if -1 value found.

perf: Skip and warn on unknown format 'configN' attrs
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.

KVM: selftests: Fix number of pages for memory slot in memslot_modification_stress_test
It's required by vm_userspace_mem_region_add() that memory size
should be aligned to host page size. However, one guest page is
provided by memslot_modification_stress_test. It triggers failure
in the scenario of 64KB-page-size-host and 4KB-page-size-guest,
as the following messages indicate.
# ./memslot_modification_stress_test
Testing guest mode: PA-bits:40, VA-bits:48, 4K pages
guest physical test memory: [0xffbfff0000, 0xffffff0000)

Number of guest pages is not compatible with the host. Try npages=16
Fix the issue by providing 16 guest pages to the memory slot for this
particular combination of 64KB-page-size-host and 4KB-page-size-guest
on aarch64.

mm/selftest: uffd: explain the write missing fault check
It's not obvious why we had a write check for each of the missing messages, especially when it should be a locking op. Add a rich comment for that, and also try to explain its good side and limitations, so that if someone hit it again for either a bug or a different glibc impl there'll be some clue to start with.

perf tools changes for v6.1: 1st batch
- Add support for AMD on 'perf mem' and 'perf c2c', the kernel enablement
patches went via tip.
Example:
$ sudo perf mem record -- -c 10000
^C[ perf record: Woken up 227 times to write data ]
[ perf record: Captured and wrote 58.760 MB perf.data (836978 samples) ]
$ sudo perf mem report -F mem,sample,snoop
Samples: 836K of event 'ibs_op//', Event count (approx.): 8418762
Memory access Samples Snoop
N/A 700620 N/A
L1 hit 126675 N/A
L2 hit 424 N/A
L3 hit 664 HitM
L3 hit 10 N/A
Local RAM hit 2 N/A
Remote RAM (1 hop) hit 8558 N/A
Remote Cache (1 hop) hit 3 N/A
Remote Cache (1 hop) hit 2 HitM
Remote Cache (2 hops) hit 10 HitM
Remote Cache (2 hops) hit 6 N/A
Uncached hit 4 N/A
$
- "perf lock" improvements:
- Add -E/--entries option to limit the number of entries to display, say to ask for
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.

0xffffffffc03b5c47 bpf_prog_bf07ae9e2cbd02c5_contention_begin+0x117

0xffffffffbb841015 tick_do_update_jiffies64+0x25
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 record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.000 MB - ]

8.30% 0x7f96f0855028

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.

- Yu Zhao's Multi-Gen LRU patches are here. They've been under test in
linux-next for a couple of months without, to my knowledge, any negative reports (or any positive ones, come to that). - Also the Maple Tree from Liam R. Howlett. An overlapping range-based tree for vmas. It it apparently slight more efficient in its own right, but is mainly targeted at enabling work to reduce mmap_lock contention. Liam has identified a number of other tree users in the kernel which could be beneficially onverted to mapletrees. Yu Zhao has identified a hard-to-hit but "easy to fix" lockdep splat (https://lkml.kernel.org/r/CAOUHufZabH85CeUN-MEMgL8gJGzJEWUrkiM58JkTbBhh-jew0Q@mail.gmail.com). This has yet to be addressed due to Liam's unfortunately timed vacation. He is now back and we'll get this fixed up. - Dmitry Vyukov introduces KMSAN: the Kernel Memory Sanitizer. It uses clang-generated instrumentation to detect used-unintialized bugs down to the single bit level. KMSAN keeps finding bugs. New ones, as well as the legacy ones. - Yang Shi adds a userspace mechanism (madvise) to induce a collapse of memory into THPs. - Zach O'Keefe has expanded Yang Shi's madvise(MADV_COLLAPSE) to support file/shmem-backed pages. - userfaultfd updates from Axel Rasmussen - zsmalloc cleanups from Alexey Romanov - cleanups from Miaohe Lin: vmscan, hugetlb_cgroup, hugetlb and memory-failure - Huang Ying adds enhancements to NUMA balancing memory tiering mode's page promotion, with a new way of detecting hot pages. - memcg updates from Shakeel Butt: charging optimizations and reduced memory consumption. - memcg cleanups from Kairui Song. - memcg fixes and cleanups from Johannes Weiner. - Vishal Moola provides more folio conversions - Zhang Yi removed ll_rw_block() :( - migration enhancements from Peter Xu - migration error-path bugfixes from Huang Ying - Aneesh Kumar added ability for a device driver to alter the memory tiering promotion paths.
