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.
The rteval test now has two new options:
--loads-cpulist=[cpulist] - determines which CPUs will have load threads
--measurement-cpulist=[cpulist] - determines on which CPUs measurement threads will run
These options enable rteval to place the load thread or threads on one set of CPUs and the measurement threads on a different set of CPUs. If only the --measurement-cpulist option is specified, the loads-cpulist will default to it's compliment.
The rteval utility has two options used to specify which cpu cores the measurement and load processes should use.
If --measurement-cpulist is specified and --loads-cpulist is not, then default the load cpulist to be the inverse of the measurement cpulist. That is, on an 8-core system if --measurement-cpulist is 0-4, make --loads-cpulist be 5-7.
Created attachment 1155465[details]
default cpulist for modules
if only one of the cpulist options (--measurement-cpulist and
--loads-cpulist) is specified, default the unspecified cpulist to
be the inverse of the specified list.
