Remove this from check-headers.sh:
opts="--ignore-blank-lines --ignore-space-change"
as the easiest policy is to just follow the upstream UAPI header version 100%.
Pure space-only changes are comparatively rare.

Certain systems are designed to have sparse/discontiguous nodes. On
such systems, 'perf bench numa' hangs, shows wrong number of nodes and
shows values for non-existent nodes. Handle this by only taking nodes
that are exposed by kernel to userspace.

The s390x CPU sampling and measurement facilities do not support perf
events of type PERF_TYPE_BREAKPOINT. The test cases are executed and
fail with -ENOENT due to missing hardware support.
Disable the execution of both test cases based on a
platform check. This is the same approach as done for
PowerPC.

Test case 21 (Number of exit events of a simple workload) fails on
s390x. The reason is the invalid sample frequency supplied for this
test. On s390x the minimum sample frequency is much higher (see output
of /proc/service_levels).
Supply a save sample frequency value for s390x to fix this. The value
will be adjusted by the s390x CPUMF frequency convertion function to a
value well below the sysctl kernel.perf_event_max_sample_rate value.

Move the code to synthesize event updates for scale/unit/cpus to a
common utility file, and use it both from stat and record.
This allows to access scale and other extra qualifiers from perf script.

This allows code from 'perf stat' called from 'perf script' to access
this information.

From: Andi Kleen <ak@linux.intel.com>
Add support for computing 'perf stat' style metrics in 'perf script'.
When using leader sampling we can get metrics for each sampling period
by computing formulas over the values of the different group members.
This allows things like fine grained IPC tracking through sampling, much
more fine grained than with 'perf stat'.
The metric is still averaged over the sampling period, it is not just
for the sampling point.
This patch adds a new metric output field for 'perf script' that uses
the existing 'perf stat' metrics infrastructure to compute any metrics
supported by 'perf stat'.
For example to sample IPC:
$ perf record -e '{ref-cycles,cycles,instructions}:S' -a sleep 1
$ perf script -F metric,ip,sym,time,cpu,comm

v2:
Use evsel->priv for new fields
Port to new base line, support fp output.
Handle stats in ->stats, not ->priv
Minor cleanups
Extra explanation about the use of the term 'averaging', from Andi in the
thread in the Link: tag below:
<quote Andi>
The current samples contains the sum of event counts for a sampling period.
EventA-1 EventA-2 EventA-3 EventA-4
EventB-1 EventB-2 EventC-3
gap with no events overflow
|-----------------------------------------------------------------|
period-start period-end
^ ^
| |
previous sample current sample
So EventA = 4 and EventB = 3 at the sample point
I generate a metric, let's say EventA / EventB. It applies to the whole period.
But the metric is over a longer time which does not have the same behavior. For
example the gap above doesn't have any events, while they are clustered at the
beginning and end of the sample period.
But we're summing everything together. The metric doesn't know that the gap is
different than the busy period.
That's what I'm trying to express with averaging.

The PERF_RECORD_USER_ events are synthesized by the tool to assist in
processing the PERF_RECORD_ ones generated by the kernel, the printing
of that information doesn't come with a perf_sample structure, so, when
dumping the event fields using 'perf report -D' there were columns that
end up not being printed.
To tidy up a bit this, fake a perf_sample structure with zeroes to have
the missing columns printed and avoid the occasional surprise with that.

Print file names of files that differ. For example, instead of:
Warning: Intel PT: x86 instruction decoder differs from kernel
print:
Warning: Intel PT: x86 instruction decoder header at 'tools/perf/util/intel-pt-decoder/inat.h' differs from latest version at 'arch/x86/include/asm/inat.h'

There are just a few new defines which do not affect perf tools.
