This adds a library of shell "code" to be shared and used by future
tests that target quality testing for Arm CoreSight support in perf
and the Linux kernel.

Add test tool to be driven by further test scripts. This tool is pure
arm64 ASM with no libc usage to ensure it is the same exact
binary/code every time so it can also be re-used for many uses. It
just loops for a given fixed number of loops.

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.

Add test tool to be driven by further test scripts. This is a simple C
based test that is for arm64 with some inline ASM to manually unroll a
lot of code to have a very long sequence of commands.

+================
+CoreSight - Perf
+================
+
+ :Author: Carsten Haitzler <carsten.haitzler@arm.com>
+ :Date: June 29th, 2022
+
+Perf is able to locally access CoreSight trace data and store it to the
+output perf data files. This data can then be later decoded to give the
+instructions that were traced for debugging or profiling purposes. You
+can log such data with a perf record command like::
+
+ perf record -e cs_etm//u testbinary
+
+This would run some test binary (testbinary) until it exits and record
+a perf.data trace file. That file would have AUX sections if CoreSight
+is working correctly. You can dump the content of this file as
+readable text with a command like::
+
+ perf report --stdio --dump -i perf.data
+
+You should find some sections of this file have AUX data blocks like::
+
+ 0x1e78 [0x30]: PERF_RECORD_AUXTRACE size: 0x11dd0 offset: 0 ref: 0x1b614fc1061b0ad1 idx: 0 tid: 531230 cpu: -1
+
+ . ... CoreSight ETM Trace data: size 73168 bytes
+ Idx:0; ID:10; I_ASYNC : Alignment Synchronisation.
+ Idx:12; ID:10; I_TRACE_INFO : Trace Info.; INFO=0x0 { CC.0 }
+ Idx:17; ID:10; I_ADDR_L_64IS0 : Address, Long, 64 bit, IS0.; Addr=0x0000000000000000;
+ Idx:26; ID:10; I_TRACE_ON : Trace On.
+ Idx:27; ID:10; I_ADDR_CTXT_L_64IS0 : Address & Context, Long, 64 bit, IS0.; Addr=0x0000FFFFB6069140; Ctxt: AArch64,EL0, NS;
+ Idx:38; ID:10; I_ATOM_F6 : Atom format 6.; EEEEEEEEEEEEEEEEEEEEEEEE
+ Idx:39; ID:10; I_ATOM_F6 : Atom format 6.; EEEEEEEEEEEEEEEEEEEEEEEE
+ Idx:40; ID:10; I_ATOM_F6 : Atom format 6.; EEEEEEEEEEEEEEEEEEEEEEEE
+ Idx:41; ID:10; I_ATOM_F6 : Atom format 6.; EEEEEEEEEEEN
+ ...
+
+If you see these above, then your system is tracing CoreSight data
+correctly.
+
+To compile perf with CoreSight support in the tools/perf directory do::
+
+ make CORESIGHT=1
+
+This requires OpenCSD to build. You may install distribution packages
+for the support such as libopencsd and libopencsd-dev or download it
+and build yourself. Upstream OpenCSD is located at:
+
+ https://github.com/Linaro/OpenCSD
+
+For complete information on building perf with CoreSight support and
+more extensive usage look at:
+
+ https://github.com/Linaro/OpenCSD/blob/master/HOWTO.md
+
+
+Kernel CoreSight Support
+------------------------
+
+You will also want CoreSight support enabled in your kernel config.
+Ensure it is enabled with::
+
+ CONFIG_CORESIGHT=y
+
+There are various other CoreSight options you probably also want
+enabled like::
+
+ CONFIG_CORESIGHT_LINKS_AND_SINKS=y
+ CONFIG_CORESIGHT_LINK_AND_SINK_TMC=y
+ CONFIG_CORESIGHT_CATU=y
+ CONFIG_CORESIGHT_SINK_TPIU=y
+ CONFIG_CORESIGHT_SINK_ETBV10=y
+ CONFIG_CORESIGHT_SOURCE_ETM4X=y
+ CONFIG_CORESIGHT_CTI=y
+ CONFIG_CORESIGHT_CTI_INTEGRATION_REGS=y
+
+Please refer to the kernel configuration help for more information.
+
+Perf test - Verify kernel and userspace perf CoreSight work
+-----------------------------------------------------------
+
+When you run perf test, it will do a lot of self tests. Some of those
+tests will cover CoreSight (only if enabled and on ARM64). You
+generally would run perf test from the tools/perf directory in the
+kernel tree. Some tests will check some internal perf support like:
+
+ Check Arm CoreSight trace data recording and synthesized samples
+ Check Arm SPE trace data recording and synthesized samples
+
+Some others will actually use perf record and some test binaries that
+are in tests/shell/coresight and will collect traces to ensure a
+minimum level of functionality is met. The scripts that launch these
+tests are in the same directory. These will all look like:
+
+ CoreSight / ASM Pure Loop
+ CoreSight / Memcpy 16k 10 Threads
+ CoreSight / Thread Loop 10 Threads - Check TID
+ etc.
+
+These perf record tests will not run if the tool binaries do not exist
+in tests/shell/coresight/\*/ and will be skipped. If you do not have
+CoreSight support in hardware then either do not build perf with
+CoreSight support or remove these binaries in order to not have these
+tests fail and have them skip instead.
+
+These tests will log historical results in the current working
+directory (e.g. tools/perf) and will be named stats-\*.csv like:
+
+ stats-asm_pure_loop-out.csv
+ stats-memcpy_thread-16k_10.csv
+ ...
+
+These statistic files log some aspects of the AUX data sections in
+the perf data output counting some numbers of certain encodings (a
+good way to know that it's working in a very simple way). One problem
+with CoreSight is that given a large enough amount of data needing to
+be logged, some of it can be lost due to the processor not waking up
+in time to read out all the data from buffers etc.. You will notice
+that the amount of data collected can vary a lot per run of perf test.
+If you wish to see how this changes over time, simply run perf test
+multiple times and all these csv files will have more and more data
+appended to it that you can later examine, graph and otherwise use to
+figure out if things have become worse or better.
+
+This means sometimes these tests fail as they don't capture all the
+data needed. This is about tracking quality and amount of data
+produced over time and to see when changes to the Linux kernel improve
+quality of traces.
+
+Be aware that some of these tests take quite a while to run, specifically
+in processing the perf data file and dumping contents to then examine what
+is inside.
+
+You can change where these csv logs are stored by setting the
+PERF_TEST_CORESIGHT_STATDIR environment variable before running perf
+test like::
+
+ export PERF_TEST_CORESIGHT_STATDIR=/var/tmp
+ perf test
+
+They will also store resulting perf output data in the current
+directory for later inspection like::
+
+ perf-asm_pure_loop-out.data
+ perf-memcpy_thread-16k_10.data
+ ...
+
+You can alter where the perf data files are stored by setting the
+PERF_TEST_CORESIGHT_DATADIR environment variable such as::
+
+ PERF_TEST_CORESIGHT_DATADIR=/var/tmp
+ perf test
+
+You may wish to set these above environment variables if you wish to
+keep the output of tests outside of the current working directory for
+longer term storage and examination.

Also had to remove:
$(INSTALL) tests/shell/coresight/*.sh -m 644 '$(DESTDIR_SQ)$(perfexec_instdir_SQ)/tests/shell/coresight'
from this patch, as it makes install fail at this point in the patchset:
DESCEND plugins
GEN /tmp/build/perf/python/perf.so
INSTALL trace_plugins
INSTALL binaries
INSTALL tests
install: cannot stat 'tests/shell/coresight/*.sh': No such file or directory
make[2]: *** [Makefile.perf:1007: install-tests] Error 1
make[2]: *** Waiting for unfinished jobs....
I'll add it back when the first .sh gets added to tests/shell/coresight/

Thanks a lot!
James and me had found the merging conflict and planned to send out
email for reminding it, the right change for above section would be:
@@ -1006,7 +1014,10 @@ install-tests: all install-gtk
$(INSTALL) tests/shell/*.sh '$(DESTDIR_SQ)$(perfexec_instdir_SQ)/tests/shell'; \

It's deliberately to not add '-m 644' when install coresight test
shell scripts under the folder tests/shell/coresight/ so that we can
keep the executable permission for these scripts. On the other flip,
we set 644 mode for the scripts under tests/shell/lib/ so these
scripts will not be executed directly by perf test framework.
@Carsten, if have chance could you confirm for above change?

Not at this patch, in this patch there are no tests/shell/coresight/*.sh
which makes 'make install' to fail _at this point_, for bisectability we
can't just test at the end of the patchkit.

If you need for some .sh, coresight test's to have x set while all of
the others don't have, and you have a good reason for that, ok, we just
add a comment.

This also has to go, I'll check and fix this loop that doesn't follow

Simply to say, all lib scripts are not needed for execute permission.
Yes, it's good to add a comment for the installation steps.

Ouch, if we can update the file tests/shell/coresight/Makefile as below:
$(CLEANDIRS):
$(call QUIET_CLEAN, test-$(@:clean-%=%)) $(Q)$(MAKE) -C $(@:clean-%=%) clean >/dev/null
Then we can get output as:
# make clean
CLEAN arm64
CLEAN libtraceevent
CLEAN libapi
CLEAN libbpf
CLEAN libsubcmd
CLEAN libperf
CLEAN fixdep
CLEAN feature-detect
CLEAN python
CLEAN bpf-skel
CLEAN test-asm_pure_loop
CLEAN test-memcpy_thread
CLEAN test-thread_loop
CLEAN test-unroll_loop_thread
CLEAN core-objs
CLEAN core-progs
CLEAN core-gen
CLEAN Documentation
Sorry for inconvenience.

And for the normal build and install, somehow that $(Q) is not being
obeyed there, so I'm using straight @ for now so that we have a clean

it.

parallel builds)?
Re the Q -- is it exported? What is printed with echo $(Q).

oh sorry - indeed i didn't see this problem coming after fixing the

No need, I did some fixes taking into account the comments on this
thread, we can go on and fix things from what I have now at
acme/perf/core, which I'll send to Linus today.

Not right now, I'm now just waiting for Linus to merge what I sent, then
you can continue from upstream.

I'm not sure what you have sent to Linus? The patch series? Specific
patches?

This is weird. This shouldn't be making its way into any man page at
all. It's just a file pointing people at other parts of the kernel tree
for docs (because when I looked for docs - i found nothing for any kind
of getting started guide - I put something here as this was the obvious
place for perf related docs for testing - but was told to put the docs
elsewhere in core kernel documentation, but I put a reference here for
those who follow after to be able to more easily find it).
There is some rule somewhere it seems that makes anything perf-*.txt
into a man page. I need to rename this file it seems.

Adrian has sent a patch for renaming the file, see:
