The struct hpp_fmt_data is to keep the values for each group members so
it doesn't need to check the event index in the group.

Split the logic to print the histogram values according to the format
string. This was used in 3 different places so it's better to move out
the logic into a function.

perf sched map supports cpu filter.
However, even with cpu filters active, any context switch currently
corresponds to a separate line.
As result, context switches on irrelevant cpus result to redundant lines,
which makes the output particlularly difficult to read on wide
architectures.
Fix it by skipping printing for irrelevant CPUs.
Example snippet of output before fix:
*B0 1.461147 secs

*G0 1.517139 secs

wake-up-parallel
perf bench futex fails as below and hangs intermittently when
attempted to run on on a powerpc system:
./perf bench futex wake-parallel
Running 'futex/wake-parallel' benchmark:

In the system, where perf bench wake-up-parallel is has system
configuration of 640 cpus. After debugging, this turned out to be
a timing issue. The benchmark creates threads equal to number of
cpus and issues a futex_wait. Then it does a usleep for .1 second
before initiating futex_wake. In system configuration with more
threads, the usleep time is not enough. Patch changes the usleep
from 100000 to 200000
With the patch, ran multiple iterations and there were no issues
further seen

Perf bench epoll fails as below when attempted to run on
on a powerpc system:
./perf bench epoll wait
Running 'epoll/wait' benchmark:
Run summary [PID 627653]: 79 threads monitoring on 64 file-descriptors for 8 secs.
perf: pthread_create: No such file or directory
In the setup where this perf bench was ran, difference was that
partition had 640 CPU's, but not all CPUs were online. 80 CPUs
were online. While creating threads and using epoll_wait , code
sets the affinity using cpumask. The cpumask size used is 80
which is picked from "nrcpus = perf_cpu_map__nr(cpu)". Here the
benchmark reports fail while setting affinity for cpu number which
is greater than 80 or higher, because it attempts to set a bit
position which is not allocated on the cpumask. Fix this by changing
the size of cpumask to number of possible cpus and not the number
of online cpus.

Tool events unnecessarily open a dummy perf event which is useless
even with `perf record` which will still open a dummy event. Change
the behavior of tool events so:
- duration_time - call `rdclock` on open and then report the count as
a delta since the start in evsel__read_counter. This moves code out
of builtin-stat making it more general purpose.
- user_time/system_time - open the fd as either `/proc/pid/stat` or
`/proc/stat` for cases like system wide. evsel__read_counter will
read the appropriate field out of the procfs file. These values
were previously supplied by wait4, if the procfs read fails then
the wait4 values are used, assuming the process/thread terminated.
By reading user_time and system_time this way, interval mode, per
PID and per CPU can be supported although there are restrictions
given what the files provide (e.g. per PID can't be combined with
per CPU).
Opening any of the tool events for `perf record` is changed to return
invalid.

When multiple aggregation options are passed to perf stat the behavior
isn't clear. Consider "perf stat -A --per-socket .." and "perf stat
--per-socket -A ..", the first won't aggregate at all while the second
will do per-socket aggregation, even though the same options were
passed.
Rather than set an enum value, gather the options in a struct and
process them from most to least aggregate. This ensures the least
aggregate option always applies, so no aggregation if "-A" is passed.

Reduce the scope of stat_options to cmd_stat, and pass as an argument
to __cmd_record. This is done to make more localized changes to the
options in later patches. A side-effect of the change is to reduce the
size of a stripped PIE perf binary by 5952 bytes. The savings come
mainly in the dynamic relocation section.

Data may have lots of overlapping mmaps. The regular insert adds at
the end and relies on a later sort. For data with overlapping mappings
the sort will happen during a subsequent maps__find or
__maps__fixup_overlap_and_insert, there's never a period where the
inserted maps buffer up and a single sort happens. To avoid back to
back sorts, maintain the sort order when fixing up and
inserting. Previously the first_ending_after search was O(log n) where
n is the size of maps, and the insert was O(1) but because of the
continuous sorting was becoming O(n*log(n)). With maintaining sort
order, the insert now becomes O(n) for a memmove.

When an 'after' map is generated the 'new' map must be before it so
terminate iterating and don't resort. If the entry 'pos' is entirely
overlapped by the 'new' mapping then don't remove and insert the
mapping, just replace - again to remove sorting.

accident, e.g.
for i in "${@}"; do
__ksft_status_merge "${i}" ## 'i' has been modified
foo "${i}" ## using 'i' with an unexpected value
done
After a quick look, it looks like 'i' is currently not used after having
been modified in __ksft_status_merge(), but still, better be safe than
sorry. I saw this while modifying the same file, not because I suspected

If there is an error to create the first netns with 'setup_ns()',
'cleanup_ns()' will be called with an empty string as first parameter.
The consequences is that 'cleanup_ns()' will try to delete an invalid
netns, and wait 20 seconds if the netns list is empty.
Instead of just checking if the name is not empty, convert the string
separated by spaces to an array. Manipulating the array is cleaner, and
calling 'cleanup_ns()' with an empty array will be a no-op.

4) Fix a Coverity static analysis report to not close() a link_fd of -1
in the multi-uprobe feature detector, from Andrii Nakryiko.
5) Revert support for redirect to any xsk socket bound to the same umem
as it can result in corrupted ring state which can lead to a crash when
flushing rings. A different approach will be pursued for bpf-next to
address it safely, from Magnus Karlsson.
6) Fix inet_csk_accept prototype in test_sk_storage_tracing.c which caused

Let's test that we can have shared zeropages in our process as long as
storage keys are not getting used, that shared zeropages are properly
unshared (replaced by anonymous pages) once storage keys are enabled,
and that no new shared zeropages are populated after storage keys
were enabled.
We require the new pagemap interface to detect the shared zeropage.
On an old kernel (zeropages always disabled):
# ./s390x/shared_zeropage_test
TAP version 13
1..3
not ok 1 Shared zeropages should be enabled
ok 2 Shared zeropage should be gone
ok 3 Shared zeropages should be disabled
# Totals: pass:2 fail:1 xfail:0 xpass:0 skip:0 error:0
On a fixed kernel:
# ./s390x/shared_zeropage_test
TAP version 13
1..3
ok 1 Shared zeropages should be enabled
ok 2 Shared zeropage should be gone
ok 3 Shared zeropages should be disabled
# Totals: pass:3 fail:0 xfail:0 xpass:0 skip:0 error:0
Testing of UFFDIO_ZEROPAGE can be added later.

Ingo reported that he was seeing these when hitting Control+C during a
perf tools build:
Makefile.perf:1149: *** Missing bpftool input for generating vmlinux.h. Stop.
The failure happens when you don't have vmlinux.h or vmlinux with BTF.
ifeq ($(VMLINUX_H),)
ifeq ($(VMLINUX_BTF),)
$(error Missing bpftool input for generating vmlinux.h)
endif
endif
VMLINUX_BTF can be empty if you didn't build a kernel or it doesn't have
a BTF section and the current kernel also has no BTF. This is totally
ok.
But VMLINUX_H should be set to the minimal version in the source tree
(unless you overwrite it manually) when you don't pass GEN_VMLINUX_H=1
(which requires VMLINUX_BTF should not be empty). The problem is that
it's defined in Makefile.config which is not included for `make clean`.

To get the changes in:

02a0a04676fa7796 ("arm64: cputype: Add Cortex-X4 definitions")
f4d9d9dcc70b96b5 ("arm64: Add Neoverse-V2 part")
That makes this perf source code to be rebuilt:
CC /tmp/build/perf-tools/util/arm-spe.o
The changes in the above patch add MIDR_NEOVERSE_V[23] and
MIDR_NEOVERSE_V1 is used in arm-spe.c, so probably we need to add those
and perhaps MIDR_CORTEX_X4 to that array? Or maybe we need to leave this
for later when this is all tested on those machines?
static const struct midr_range neoverse_spe[] = {
MIDR_ALL_VERSIONS(MIDR_NEOVERSE_N1),
MIDR_ALL_VERSIONS(MIDR_NEOVERSE_N2),
MIDR_ALL_VERSIONS(MIDR_NEOVERSE_V1),
{},
};
Mark Rutland recommended about arm-spe.c:
"I would not touch this for now -- someone would have to go audit the
TRMs to check that those other cores have the same encoding, and I think
it'd be better to do that as a follow-up."
That addresses this perf build warning:

When building with clang, via:
make LLVM=1 -C tools/testing/selftests
...clang issues this warning:
futex_requeue_pi.c:403:17: warning: passing 'const char **' to parameter
of type 'char **' discards qualifiers in nested pointer types
[-Wincompatible-pointer-types-discards-qualifiers]
This warning fires because test_name is passed into asprintf(3), which
then changes it.
Fix this by simply removing the const qualifier. This is a local
automatic variable in a very short function, so there is not much need
to use the compiler to enforce const-ness at this scope.

It's slightly better to set _GNU_SOURCE in the source code, but if one
must do it via the compiler invocation, then the best way to do so is
this:
$(CC) -D_GNU_SOURCE=
...because otherwise, if this form is used:
$(CC) -D_GNU_SOURCE
...then that leads the compiler to set a value, as if you had passed in:
$(CC) -D_GNU_SOURCE=1
That, in turn, leads to warnings under both gcc and clang, like this:
futex_requeue_pi.c:20: warning: "_GNU_SOURCE" redefined
Fix this by using the "-D_GNU_SOURCE=" form.

perf_event_open reporting:

In general a read fills 4kb so filling the buffer is a 1 in 4096
operation, move it out of the io__get_char function to avoid some
checking overhead and to better hint the function is good to inline.

small improvement to kallsyms-parsing with a default build.

Recent commit 0cfe71f45f42 ("netdev: add queue stats") added
a lot of useful stats, but only those immediately needed by virtio.
Presumably virtio does not support CHECKSUM_COMPLETE,
so statistic for that form of checksumming wasn't included.
Other drivers will definitely need it, in fact we expect it
to be needed in net-next soon (mlx5). So let's add the definition
of the counter for CHECKSUM_COMPLETE to uAPI in net already,
so that the counters are in a more natural order (all subsequent
counters have not been present in any released kernel, yet).
