Hi All, CPU isolation is not working in starlingx 5.0. Static CPU manager policy has been enabled on all the nodes and the Isol-CPU resource plugin is up &running but there is no isolated CPU resource pool visible. Could not see any isolated CPU annotations (windriver.com/isolcpus CPU annotations). Is there any additional step to get this working?
