<p>An update that contains one feature can now be installed.</p>
<h2>Description:</h2>
<p>This update for rt-tests fixes the following issues:</p>
<p>Version update from 2.2 to 2.4 (jsc#SLE-23995):</p>
<ul>
<li>Add aarch64 support for oslat</li>
<li>Add the <code>--default-system</code> option in cyclictest
This runs cyclictest without attempting any tuning. Power management is not suppressed so cyclictest measures the
system as it is configured. This may result in worse realtime behaviour, but is sometimes what you are trying to
measure.</li>
<li>Fix parsing of affinity when there is a space</li>
<li>Fixes in cyclicdeadline and deadline_test to prevent double mounting of cgroups</li>
<li>Fixes in cyclictest to address memory access violation issues for verbose with no affinity mask</li>
<li>hwlatdetect: Add option to specify cpumask</li>
<li>Increase the buf size to 2048 when parse cpuinfo</li>
<li>oslat: Print offending cpu number when above threshold</li>
<li>rt-numa: ignore runtime cpumask if '-a CPULIST' is specified</li>
<li>Significant clean-ups and fixes to hwlatdetect</li>
<li>For the complete list of changes you can consult:</li>
<li>2.4: https://lore.kernel.org/linux-rt-users/20220708150017.13462-1-jkacur@redhat.com/</li>
<li>2.3: https://lore.kernel.org/linux-rt-users/20211210184649.11084-1-jkacur@redhat.com/</li>
<li>Backport runtime fixes from upcomming release:</li>
<li>Fix threads being affined even when '-a' isn't set when using cyclictest</li>
<li>Remove arbitrary num of threads limits</li>
<li>Add error checking to connect and getsockname</li>
<li>Update hwlatdetect to integer division to prevent an error when calculating width, which assumes an integer</li>
</ul>
