mm: discard __GFP_ATOMIC
__GFP_ATOMIC serves little purpose. Its main effect is to set ALLOC_HARDER which adds a few little boosts to increase the chance of an allocation succeeding, one of which is to lower the water-mark at which it will succeed. It is *always* paired with __GFP_HIGH which sets ALLOC_HIGH which also adjusts this watermark. It is probable that other users of __GFP_HIGH should benefit from the other little bonuses that __GFP_ATOMIC gets. __GFP_ATOMIC also gives a warning if used with __GFP_DIRECT_RECLAIM. There is little point to this. We already get a might_sleep() warning if __GFP_DIRECT_RECLAIM is set. __GFP_ATOMIC allows the "watermark_boost" to be side-stepped. It is probable that testing ALLOC_HARDER is a better fit here. __GFP_ATOMIC is used by tegra-smmu.c to check if the allocation might sleep. This should test __GFP_DIRECT_RECLAIM instead. This patch: - removes __GFP_ATOMIC - allows __GFP_HIGH allocations to ignore watermark boosting as well as GFP_ATOMIC requests. - makes other adjustments as suggested by the above. The net result is not change to GFP_ATOMIC allocations. Other allocations that use __GFP_HIGH will benefit from a few different extra privileges. This affects: xen, dm, md, ntfs3 the vermillion frame buffer hibernation ksm swap all of which likely produce more benefit than cost if these selected allocation are more likely to succeed quickly.

perf auxtrace: Fix address filter duplicate symbol selection
When a match has been made to the nth duplicate symbol, return
success not error.
Example:
Before:
$ cat file.c
cat: file.c: No such file or directory
$ cat file1.c
#include <stdio.h>
static void func(void)
{
printf("First func\n");
}
void other(void);
int main()
{
func();
other();
return 0;
}
$ cat file2.c
#include <stdio.h>
static void func(void)
{
printf("Second func\n");
}
void other(void)
{
func();
}
$ gcc -Wall -Wextra -o test file1.c file2.c
$ perf record -e intel_pt//u --filter 'filter func @ ./test' -- ./test
Multiple symbols with name 'func'
#1 0x1149 l func
which is near main
#2 0x1179 l func
which is near other
Disambiguate symbol name by inserting #n after the name e.g. func #2
Or select a global symbol by inserting #0 or #g or #G
Failed to parse address filter: 'filter func @ ./test'
Filter format is: filter|start|stop|tracestop <start symbol or address> [/ <end symbol or size>] [@<file name>]
Where multiple filters are separated by space or comma.
$ perf record -e intel_pt//u --filter 'filter func #2 @ ./test' -- ./test
Failed to parse address filter: 'filter func #2 @ ./test'
Filter format is: filter|start|stop|tracestop <start symbol or address> [/ <end symbol or size>] [@<file name>]
Where multiple filters are separated by space or comma.
After:

perf build: Fix build error when NO_LIBBPF=1
The $(LIBBPF) target should only be a dependency of prepare if the
static version of libbpf is needed. Add a new LIBBPF_STATIC variable
that is set by Makefile.config. Use LIBBPF_STATIC to determine whether
the CFLAGS, etc. need updating and for adding $(LIBBPF) as a prepare
dependency.
As Makefile.config isn't loaded for "clean" as a target, always set
LIBBPF_OUTPUT regardless of whether it is needed for $(LIBBPF). This
is done to minimize conditional logic for $(LIBBPF)-clean.
This issue and an original fix was reported by Mike Leach in:

perf tests bpf prologue: Fix bpf-script-test-prologue test compile issue with clang
While running 'perf test' for bpf, observed that "BPF prologue

The test code tests/bpf-script-test-prologue.c uses fmode_t. And the
error above is for "fmode_t" which is defined in include/linux/types.h
as part of kernel build directory: "/lib/modules/<kernel_version>/build"
that comes from kernel devel [ soft link to /usr/src/<kernel_version> ].
Clang picks this header file from "-working-directory" build option that
specifies this build folder.

perf tools: Fix build on uClibc systems by adding missing sys/types.h include
Not all libc implementations define ssize_t as part of stdio.h like
glibc does since the standard only requires this type to be defined by
unistd.h and sys/types.h. For this reason the perf build is currently
broken for toolchains based on uClibc, for instance.
Include sys/types.h explicitly to fix that.
Committer notes:
In addition, in the past this worked in uClibc test systems as there was
another way to get to sys/types.h that got removed in that cset:
tools/perf/util/trace-event.h
/usr/include/traceevent/event_parse.h # This got removed from util/trace-event.h in

perf stat: Fix handling of --for-each-cgroup with --bpf-counters to match non BPF mode
The --for-each-cgroup can have the same cgroup multiple times, but this
confuses BPF counters (since they have the same cgroup id), making only
the last cgroup events to be counted.
Let's check the cgroup name before adding a new entry to the cgroups
list.
Before:
$ sudo ./perf stat -a --bpf-counters --for-each-cgroup /,/ sleep 1
Performance counter stats for 'system wide':

After it becomes similar to the non-BPF mode:
$ sudo ./perf stat -a --bpf-counters --for-each-cgroup /,/ sleep 1
Performance counter stats for 'system wide':
8,013.38 msec cpu-clock / # 7.998 CPUs utilized

Committer notes:
As a reminder, to test with BPF counters one has to use BUILD_BPF_SKEL=1
in the make command line and have clang/llvm installed when building
perf, otherwise the --bpf-counters option will not be available:
# perf stat -a --bpf-counters --for-each-cgroup /,/ sleep 1
Error: unknown option `bpf-counters'

perf stat: Fix handling of unsupported cgroup events when using BPF counters
When --for-each-cgroup option is used, it fails when any of events is
not supported and exits immediately. This is not how 'perf stat'
handles unsupported events.
Let's ignore the failure and proceed with others so that the output is
similar to when BPF counters are not used:
Before:
$ sudo ./perf stat -a --bpf-counters -e L1-icache-loads,L1-dcache-loads --for-each-cgroup system.slice,user.slice sleep 1
Failed to open first cgroup events
$
After it shows output similat to when --bpf-counters isn't specified:
$ sudo ./perf stat -a --bpf-counters -e L1-icache-loads,L1-dcache-loads --for-each-cgroup system.slice,user.slice sleep 1
Performance counter stats for 'system wide':

The issue is in function machine__is_lock_function() in file
./util/machine.c lines 3355:
/* should not fail from here */
sym = machine__find_kernel_symbol_by_name(machine, "__sched_text_end", &kmap);
machine->sched.text_end = kmap->unmap_ip(kmap, sym->start)
On s390 the symbol __sched_text_end is *NOT* in the symbol list and the
resulting pointer sym is set to NULL. The sym->start is then a NULL pointer
access and generates the core dump.
The reason why __sched_text_end is not in the symbol list on s390 is
simple:
When the symbol list is created at perf start up with function calls
dso__load
+--> dso__load_vmlinux_path
+--> dso__load_vmlinux
+--> dso__load_sym
+--> dso__load_sym_internal (reads kernel symbols)
+--> symbols__fixup_end
+--> symbols__fixup_duplicate
The issue is in function symbols__fixup_duplicate(). It deletes all
symbols with have the same address. On s390:
# nm -g ~/linux/vmlinux| fgrep c68390
0000000000c68390 T __cpuidle_text_start
0000000000c68390 T __sched_text_end
#
two symbols have identical addresses and __sched_text_end is considered
duplicate (in ascending sort order) and removed from the symbol list.
Therefore it is missing and an invalid pointer reference occurs. The
code checks for symbol __sched_text_start and when it exists assumes
symbol __sched_text_end is also in the symbol table. However this is not
the case on s390.
Same situation exists for symbol __lock_text_start:
0000000000c68770 T __cpuidle_text_end
0000000000c68770 T __lock_text_start
This symbol is also removed from the symbol table but used in function
machine__is_lock_function().
To fix this and keep duplicate symbols in the symbol table, set
symbol_conf.allow_aliases to true. This prevents the removal of
duplicate symbols in function symbols__fixup_duplicate().

perf test record_probe_libc_inet_pton: Fix failure due to extra inet_pton() backtrace in glibc >= 2.35
Starting with glibc 2.35 there are extra inet_pton() calls when doing a
IPv6 ping as in one of the 'perf test' entry, which makes it fail:
# perf test inet_pton
89: probe libc's inet_pton & backtrace it with ping : FAILED!
#
If we look at what this script is expecting (commenting out the removal
of the temporary files in it):
# cat /tmp/expected.aT6
ping[][0-9 \.:]+probe_libc:inet_pton: \([[:xdigit:]]+\)
.*inet_pton\+0x[[:xdigit:]]+[[:space:]]\(/usr/lib64/libc.so.6|inlined\)$
getaddrinfo\+0x[[:xdigit:]]+[[:space:]]\(/usr/lib64/libc.so.6\)$
.*(\+0x[[:xdigit:]]+|\[unknown\])[[:space:]]\(.*/bin/ping.*\)$
#
And looking at what we are getting out of 'perf script', to match with
the above:
# cat /tmp/perf.script.IUC
ping 623883 [006] 265438.471610: probe_libc:inet_pton: (7f32bcf314c0)

fa6c6 getaddrinfo+0x126 (/usr/lib64/libc.so.6)
491e [unknown] (/usr/bin/ping)
#
We see that its just the first call to inet_pton() that didn't came thru
getaddrinfo(), so if we ignore the first the script matches what it
expects, testing that using 'perf probe' + 'perf record' + 'perf script'
with callchains on userspace targets is producing the expected results.
Since we don't have a 'perf script --skip' to help us here, use tac +
grep to do that, resulting in a one liner that makes this script work on
both older glibc versions as well as with 2.35.
With it, on fedora 36, x86, glibc 2.35:
# perf test inet_pton
90: probe libc's inet_pton & backtrace it with ping : Ok
# perf test -v inet_pton
90: probe libc's inet_pton & backtrace it with ping :

perf tools: Fix segfault when trying to process tracepoints in perf.data and not linked with libtraceevent
When we have a perf.data file with tracepoints, such as:
# perf evlist -f
probe_perf:lzma_decompress_to_file
# Tip: use 'perf evlist --trace-fields' to show fields for tracepoint events
#
We end up segfaulting when using perf built with NO_LIBTRACEEVENT=1 by
trying to find an evsel with a NULL 'event_name' variable:
(gdb) run report --stdio -f
Starting program: /root/bin/perf report --stdio -f
Program received signal SIGSEGV, Segmentation fault.

perf tools fixes and improvements for v6.2: 2nd batch
- Don't stop building perf if python setuptools isn't installed, just
disable the affected perf feature.
- Remove explicit reference to python 2.x devel files, that warning is
about python-devel, no matter what version, being unavailable and thus
disabling the linking with libpython.
- Don't use -Werror=switch-enum when building the python support that
handles libtraceevent enumerations, as there is no good way to test
if some specific enum entry is available with the libtraceevent
installed on the system.
- Introduce 'perf lock contention' --type-filter and --lock-filter, to
filter by lock type and lock name:

perf scripting python: Don't be strict at handling libtraceevent enumerations
The build was failing on archlinux because it has a newer libtraceevent
that added a new entry to the tep_print_arg_type enum:
19.72 archlinux:base : FAIL gcc version 12.2.0 (GCC)
util/scripting-engines/trace-event-python.c: In function ‘define_event_symbols’:
util/scripting-engines/trace-event-python.c:281:9: error: enumeration value ‘TEP_PRINT_CPUMASK’ not handled in switch [-Werror=switch-enum]
281 | switch (args->type) {
| ^~~~~~
cc1: all warnings being treated as errors
Since we build with distros that have different versions of
libtraceevent and there is no way to easily test if these enum entries
are available, just disable -Werror=switch-enum for that specific
object.

perf arm64: Simplify mksyscalltbl
This patch isn't intended to have any effect on the compiled code. It just removes one level of indirection: calling the *host* compiler to build and then run a program that just printf:s the numerical entries of the syscall-table. In other words, the generated syscalls.c changes from: [46] = "ftruncate", to: [__NR3264_ftruncate] = "ftruncate", The latter is as good as the former to the user of perf, and this can be done directly by the shell-script. The syscalls defined as non-literal values (like "#define __NR_ftruncate __NR3264_ftruncate") are trivially resolved at compile-time without namespace-leaking and/or collision for its sole user, perf/util/syscalltbl.c, that just #includes the generated file. A future "-mabi=32" support would probably have to handle this differently, but that is a pre-existing problem not affected by this simplification. Calling the *host* compiler only complicates things and accidentally can get a completely wrong set of files and syscall numbers, see earlier commits. Note that the script parameter hostcc is now unused. At the time of this patch, powerpc (the origin, see comments), and also e.g. x86 has moved on, from filtering "gcc -dM -E" output to reading separate specific text-file, a table of syscall numbers. IMHO should arm64 consider adopting this.

perf vendor events amd: Add Zen 4 metrics
Add metrics taken from Section 2.1.15.2 "Performance Measurement" in the Processor Programming Reference (PPR) for AMD Family 19h Model 11h Revision B1 processors. The recommended metrics are sourced from Table 27 "Guidance for Common Performance Statistics with Complex Event Selects". The pipeline utilization metrics are sourced from Table 28 "Guidance for Pipeline Utilization Analysis Statistics". These are new to Zen 4 processors and useful for finding performance bottlenecks by analyzing activity at different stages of the pipeline. Metric groups have been added for Level 1 and Level 2 analysis.

Update the ivybridge 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 events are unchanged but the version number is 23 to match the perfmon version. In the events unused json values are removed. The formatting changes increase consistency across the json files.

perf vendor events intel: Refresh icelakex metrics and events
Update the icelakex 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 1.17, in particular uncore, with fixes to uncore events and improved descriptions. The formatting changes increase consistency across the json files.
