Now the attr tests are shell tests move the associated python and
configuration files. Update the installation build rules for the new
directories. Recycle the lib install rules for python files allowing
the explicit attr.py install line to be dropped.

perf test 17 'Setup struct perf_event_attr' fails on s390 z/VM guest,
using linux-next kernel.
Root cause is the fall-back from hardware counter cycles
perf_event_attr:
type 0 (PERF_TYPE_HARDWARE)
size 136
config 0 (PERF_COUNT_HW_CPU_CYCLES)
{ sample_period, sample_freq } 4000
sample_type IP|TID|TIME|ADDR|PERIOD|DATA_SRC
read_format ID|LOST
which returns -ENOENT on s390 z/VM guest. This causes the code to fall
back to software counter task-clock, as can be seen in the debug output:
------------------------------------------------------------
perf_event_attr:
type 1 (PERF_TYPE_SOFTWARE)
size 136
config 0x1 (PERF_COUNT_SW_TASK_CLOCK) <-here
{ sample_period, sample_freq } 4000
sample_type IP|TID|TIME|ADDR|PERIOD|DATA_SRC
read_format ID|LOST
This succeeds on s390 z/VM guest.
This successful installation of the counter task-clock is not listed in
the expected results and the test case fails.
This is caused by commit eb2eac0c7b618033 ("perf evsel: Fallback to
"task-clock" when not system wide") which introduced fall back from
event 'cycles' to event 'task-clock'.
To fix this on s390 allow event number 0 (cycles) and event number 1
(task-clock) as expected result.

This test case fails on s390 virtual machine z/VM which has no PMU support
when the perf tool is built with LIBPFM4=1.
Using make LIBPFM4=1 builds the perf tool with support for libpfm
event notation. The command line flag --pfm-events is valid:
# ./perf record --pfm-events cycles -- true
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.001 MB perf.data (2 samples) ]
#
However the command 'perf test -Fv 17' fails on s390 z/VM virtual machine
with LIBPFM4=1:
# perf test -Fv 17
17: Setup struct perf_event_attr :
--- start ---
.....
running './tests/attr/test-record-group2'
unsupp './tests/attr/test-record-group2'
running './tests/attr/test-record-pfm-period'
expected exclude_hv=0, got 1
FAILED './tests/attr/test-record-pfm-period' - match failure
---- end ----
Setup struct perf_event_attr: FAILED!
When --pfm-event system is not supported, the test returns unsupported
and continues. Here is an example using a virtual machine on x86 and
Fedora 34:
[root@f33 perf]# perf test -Fv 17
17: Setup struct perf_event_attr :
--- start ---
.....
running './tests/attr/test-record-group2'
unsupp './tests/attr/test-record-group2'
running './tests/attr/test-record-pfm-period'
unsupp './tests/attr/test-record-pfm-period'
....
The issue is file ./tests/attr/test-record-pfm-period
which requires perf event attribute member exclude_hv to be zero.
This is not the case on s390 where the value of exclude_hv is one when
executing on a z/VM virtual machine without PMU hardware support.
Fix this by allowing value exlucde_hv to be zero or one.
Output before:
# /usr/bin/python ./tests/attr.py -d ./tests/attr/ -t \
test-record-pfm-period -p ./perf -vvv 2>&1| fgrep match

Output after:

matching [event:base-record]
match: [event:base-record] matches ['event-1-0-6', 'event-1-0-5']
matched
Background:
Using libpfm library ends up in this function call sequence
pfm_get_perf_event_encoding()
+-- pfm_get_os_event_encoding()
+-- pfmlib_perf_event_encode()
is called when no hardware specific PMU unit can be detected
as in the s390 z/VM virtual machine case. This uses the
"perf_events generic PMU" data structure which sets exclude_hv
to 1 per default. Using this PMU that test case always fails.
That is the reason why exclude_hv attribute setting varies.
Version 2:
As suggested by Ian Rogers make perf_event_attribute member
exclude_hv more robust and accept value 0 or 1 to handle more
test cases which might fail on s390 virtual machine z/VM.

Add kernel AUX area sampling definitions, which brings perf_event.h into
line with the kernel version.
New sample type PERF_SAMPLE_AUX requests a sample of the AUX area
buffer. New perf_event_attr member 'aux_sample_size' specifies the
desired size of the sample.
Also add support for parsing samples containing AUX area data i.e.
PERF_SAMPLE_AUX.
Committer notes:
I squashed the first two patches in this series to avoid breaking
automatic bisection, i.e. after applying only the original first patch
in this series we would have:
# perf test -v parsing
26: Sample parsing :
--- start ---
test child forked, pid 17018
sample format has changed, some new PERF_SAMPLE_ bit was introduced - test needs updating
test child finished with -1
---- end ----
Sample parsing: FAILED!
#
With the two paches combined:
# perf test parsing
26: Sample parsing : Ok

We synthesize an update event that needs to touch the evsel id array,
which is not defined at that time. Fix this by forcing the id allocation
for events with their unit defined.

We have a one of the event open fallback case in __perf_evsel__open
where we zero exclude_guest|exclude_host fields.
This means there's no way for attr tests to find out what's the right
value for those fields, so we need to check for both 0 and 1. Luckily we
still have other event parsing tests for those fields.
