Based on above logs, we could see some of the hv-24x7 metric events
fails, and logs suggest to run the metric event with -a option. This
change happened after the commit a4b8cfcabb ("perf stat: Delay
metric parsing"), which delayed the metric parsing phase and now before
metric parsing phase perf tool identifies, whether target is system-wide
or not. With this change, perf_event_open will fails with workload
monitoring for uncore events as expected.
The perf all metric test case fails as some of the hv-24x7 metric events
may need bigger workload with system wide monitoring to get the data.
Fix this issue by changing current system wide check from true workload
to sleep 0.01 workload.
Result with the patch changes in powerpc:

Parametrized events are not only a powerpc domain. They occur on other
platforms too (e.g. aarch64). They should be ignored in this testcase,
since proper setup of the parameters is out of scope of this script.
Let's not filter them out by PMU name, but rather based on the fact that
they expect a parameter.

Commit f4a2aade68 ("perf tests powerpc: Fix branch stack sampling
test to include sanity check for branch filter") added a skip if certain
branch options aren't available.
But the change added both -b (--branch-any) and --branch-filter options
at the same time, which will always result in a failure on any platform
because the arguments can't be used together.
Fix this by removing -b (--branch-any) and leaving --branch-filter which
already specifies 'any'. Also add warning messages to the test and perf
tool.
Output on x86 before this fix:

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.

Add a script to drive the asm pureloop test for arm64/CoreSight that
gathers data so it passes a minimum bar for amount and quality of
content that we extract from the kernel's perf support.
Committer notes:
Add the install of tests/shell/coresight/*.sh to
tools/perf/Makefile.perf as we're starting to populate that dir.

Add test tool to be driven by further test scripts. This tool is pure

This adds the initial build infrastructure (makefiles maintainers
information) for adding follow-on tests for CoreSight.
Committer notes:
Remove the installation of tests/shell/coresight/*.sh, as there are no
files there yet and thus, at this point, make install fails.
Use $(QUIET_CLEAN) to avoid having extraneous output in the 'make clean'
output.
Also use @$(MAKE) in tools/perf/tests/shell/coresight/Makefile as $(Q)
is not turning into @ when V=1 isn't used, i.e. in the default case it
is not being quiet.
The >/dev/null in the all for tools/perf/tests/shell/coresight/Makefile
is to avoid this:
make[4]: Nothing to be done for 'all'.
make[4]: Nothing to be done for 'all'.
make[4]: Nothing to be done for 'all'.
DESCEND plugins
GEN /tmp/build/perf/python/perf.so

INSTALL trace_plugins
On !arm64 where nothing is done on the main target for
tools/perf/tests/shell/coresight/*/Makefile.

The test is designed with a data structure with 64-byte alignment, it
has two fields "data1" and "data2", and other fields are reserved.
Using the "perf mem" command, we can record and report memory samples
for a self-contained workload with 1 second duration. If no samples are
obtained for the data structure "buf1", it reports failure; and by
checking the offset in structure "buf1", if the memory samples aren't
for the "data1" and "data2" fields, it means wrong data symbol parsing
and returns failure.

This currently fails to parse as the left hand side if expression needs
to be in parentheses. By allowing the if expression to have a right hand
side that is an if expression we can parse the expression above, with
left to right evaluation order that matches languages like Python.

When tracing the kernel with Intel PT, text_poke events are recorded
per-cpu. In per-thread mode that results in a mixture of per-thread and
per-cpu events and mmaps. Check that happens correctly.
The debug output from perf record -vvv is recorded and then awk used to
process the debug messages that indicate what file descriptors were
opened and whether they were mmapped or set-output.

The perf probe related tests like probe_vfs_getname.sh which
is in "tools/perf/tests/shell" directory have dependency on
debuginfo information in the kernel. Currently debuginfo
check is handled by skip_if_no_debuginfo function in the
file "lib/probe_vfs_getname.sh". skip_if_no_debuginfo function
looks for this specific error log from perf probe to skip
the testcase:
<<>>
Failed to find the path for the kernel|Debuginfo-analysis is
not supported
<>>
But in some case, like this one in powerpc, while running this
test, observed error logs is:
<<>>
The /lib/modules/<version>/build/vmlinux file has no debug information.
Rebuild with CONFIG_DEBUG_INFO=y, or install an appropriate debuginfo
package.
Error: Failed to add events.
<<>>
Update the skip_if_no_debuginfo function to include the above
error, to skip the test in these scenarios too.
