From 636701e66cb98b979948b7a47320809c734e2a9e Mon Sep 17 00:00:00 2001

Subject: [PATCH] rteval: Add relative cpulists for loads
Relative cpulists were added for measurements in 64ce7848 ("rteval: Add
relative cpulists for measurements"). It was observed since that this
feature would also be useful for load cpulists, for example when the
measurements are performed externally and rteval is only used to run
loads.
Add support for relative cpulists also for loads. This works the same
way as for measurements using parse_cpulist_from_config, only difference
is there is no --loads-run-on-isolcpus option. That is, --loads-cpulist
now also takes lists with addition (+) and removal (-) of CPUs against
the default list, e.g. +0,1,-7,8.

Subject: [PATCH 02/13] rteval: Add rtla timerlat as a measurement module
This is the first step to adding timerlat as a measurement module
With this change you can run timerlat as a standalone rteval file like
this (as root)
python rteval/modules/measurement/timerlat.py
You can also modify your rteval.conf to list timerlat in the
[measurement] section, for example like this
[measurement]
cyclictest: module
timerlat: module
and then both measurement moduels will be run from rteval, for example
rteval -D -d5m --measurement-cpulist=1-5
Will run rteval with Debug info, for 5m and cyclictest and timerlat will
run on cpus 1-5 and load modules will run on the other available cpus.
Currently MakeReport just prints to standard out the same information
that timerlat outputs, in otherwords, there is no processing into xml
yet. Also, there is no way to invoke tracing at the time, but that will
be added soon!

Subject: [PATCH 08/13] rteval: Add summary reporting for timerlat
This adds an rteval section to the xsl file and generates a timerlat
report at the end of a run. To use it edit your rteval.conf file
to comment out cyclictest and uncomment timerlat
Another interesting thing you can do is uncomment both of them and
get a report from both in one run.
You can also use this with the summary report, for example
rteval -Z rteval-20240426-3/summary.xml
will work with timerlat now. (or both cyclictest and timerlat at the
same time.)

- Instead of "import as", use "from" and the requested functionality
- Obtain the default buckets from the ModuleParameters to use if a
number is not otherwise provided
- set the cpulist to "" if not otherwise provided
- add a few docstrings to functions
- obtain a default cpulist from online_cpus for the standalone test

Subject: [PATCH 10/13] rteval: Make output work with new dmiinfo format
Commit 43c45ba7 ("rteval: Implement initial dmidecode support")
re-introduced DMI information into rteval XML summary, but in a
different format, which is not correctly picked up in rteval_text.xsl
for formatting BIOS and vendor information into rteval text output.
This lead to the information not being displayed correctly:
Model: -
BIOS version: (ver: , rev :, release date: )
Modify the relevant section of rteval_text.xsl to make it understand the
new format. Also, adjust the incorrect spacing around "rev".
New output (in QEMU VM):
Model: QEMU - Standard PC (Q35 + ICH9, 2009)
BIOS version: SeaBIOS (ver: 1.16.3-1.fc39, rev: 0.0, release date: 04/01/2014)

range
As Crystal Wood <crwood@redhat.com> points out, there is no
need to setdefault when calculating the range, just use get
if there is no value.

Subject: [PATCH 11/13] rteval: cyclictest.py: reduce: Fix exception with
missing samples
If cyclictest omits a line of zeroes rather than printing it,
__samples[high] will not exist (rather than be zero). Handle this
in preparation for cyclictest doing this.
Note that get() seems more suitable than setdefault(), but the latter
is used in order to match the code in timerlat.py.

This adds calculating statitics such as samples (count), min, max, mean,
median, mode, range, absolute and standard deviations to xml
Currently it combines the kernel thread, IRQs and userspace threads into
one statistic like it does with cyclictest, but in the future we can
separate this out too.
To see this functioning from git, do this,
