RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Tereza Cerna 2018-01-12 14:03:25 UTC 
Description of problem:
=======================
There was implemented new feature for support negation in the CPU list for cpu-partitioning profile.

Currently it is implemented to exclude cpus one by one:
  # cat /etc/tuned/cpu-partitioning-variables.conf
  isolated_cores=1-20,!5,!6,!7,!8

It would be nice to exclude it together:
  # cat /etc/tuned/cpu-partitioning-variables.conf
  isolated_cores=1-20,!5-8

Version-Release number of selected component (if applicable):
=============================================================
tuned-2.9.0-1.el7.noarch
tuned-profiles-cpu-partitioning-2.9.0-1.el7.noarch

How reproducible:
=================
always

Steps to Reproduce:
===================
1. Have machine with more than 8 CPUs.

2. Fill cpu-partitioning-variables.conf:
# echo 'isolated_cores=2-6,!3-4' > /etc/tuned/cpu-partitioning-variables.conf

3. Activate profile
# tuned-adm profile cpu-partitioning

4. See log information
# cat /var/log/tuned/tuned.log | grep CPUAffinity
2018-01-12 08:44:53,505 INFO     tuned.plugins.plugin_systemd: setting 'CPUAffinity' to '0 2 3 4 5 6 7' in the '/etc/systemd/system.conf'
  
Actual results:
===============
2018-01-12 08:44:53,505 INFO     tuned.plugins.plugin_systemd: setting 'CPUAffinity' to '0 2 3 4 5 6 7' in the '/etc/systemd/system.conf'

Expected results:
=================
2018-01-12 08:44:53,505 INFO     tuned.plugins.plugin_systemd: setting 'CPUAffinity' to '0 1 3 4 7' in the '/etc/systemd/system.conf'
