Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

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.

Comment 3 John Kacur 2019-04-24 13:56:15 UTC

rpm -q kernel
kernel-4.18.0-80.18.el8.s390x
[root@ibm-z-111 tuna]# ls /proc/irq/default_smp_affinity
/proc/irq/default_smp_affinity

ls /proc/irq/1/smp_affinity
/proc/irq/1/smp_affinity


Unlike earlier kernels, the default_smp_affinity file is available, so tuna does not crash

Never-the-less, the model for IRQs works differently on s390
so although we do not crash, we do exit gracefully with an error message when trying to manipulate irqs on s390
but unfortunately I think this is the best we are able to do.

./tuna-cmd.py -c1 -i
Function: isolate_cpus , Invalid argument
