# Recommended update for rt-tests

Announcement ID: SUSE-RU-2023:0716-1  
Rating: moderate  
References:

  
Affected Products:

  * SUSE Linux Enterprise Real Time 15 SP4
  * SUSE Real Time Module 15-SP4

  
  
An update that contains one feature can now be installed.

## Description:

This update for rt-tests fixes the following issues:

Version update from 2.2 to 2.4 (jsc#SLE-23995):

  * Add aarch64 support for oslat
  * Add the `--default-system` 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.
  * Fix parsing of affinity when there is a space
  * Fixes in cyclicdeadline and deadline_test to prevent double mounting of
    cgroups
  * Fixes in cyclictest to address memory access violation issues for verbose
    with no affinity mask
  * hwlatdetect: Add option to specify cpumask
  * Increase the buf size to 2048 when parse cpuinfo
  * oslat: Print offending cpu number when above threshold
  * rt-numa: ignore runtime cpumask if '-a CPULIST' is specified
  * Significant clean-ups and fixes to hwlatdetect
  * For the complete list of changes you can consult:
  * 2.4: https://lore.kernel.org/linux-rt-
    users/20220708150017.13462-1-jkacur at redhat.com/
  * 2.3: https://lore.kernel.org/linux-rt-
    users/20211210184649.11084-1-jkacur at redhat.com/
  * Backport runtime fixes from upcomming release:
  * Fix threads being affined even when '-a' isn't set when using cyclictest
  * Remove arbitrary num of threads limits
  * Add error checking to connect and getsockname
  * Update hwlatdetect to integer division to prevent an error when calculating
    width, which assumes an integer
