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 of problem:

The cpu-partitioning profile is very relevant to the work we're doing in edge computing, but we cannot use it with RHEL for Edge as the bootloader plugin doesn't support rpm-ostree. Rather than rebuild the grub menu on an rpm system, the plugin would need to pass the options to rpm-ostree kargs --append=KEY=VALUE  and/or --replace=KEY=VALUE=NEWVALUE on an rpm-ostree system. 

 

Version-Release number of selected component (if applicable):
8.5 would be amazing


How reproducible:
100%

Steps to Reproduce:
1. configure isolated_cores in /etc/tuned/cpu-partitioning-variables.conf
2. tuned-adm profile cpu-partitioning
3. 

Actual results:
grub config does not change


Expected results:
apply the config from tuned via rpm-ostree. 

Additional info:
I don't think it would be too difficult to check if the plugin is running on an rpm-ostree system and alter it's behavior accordingly.
