The locksetup mode is the way in which the user communicates that the resource group will be used for a pseudo-locked region. Locksetup mode should thus ensure that all restrictions on a resource group are met before locksetup mode can be entered. The resource group should also be configured to ensure that it cannot be modified in unsupported ways when a pseudo-locked region. Introduce the support where the request for entering locksetup mode can be validated. This includes: CDP is not active, no cpus or tasks are assigned to the resource group, monitoring is not in progress on the resource group. Once the resource group is determined ready for a pseudo-locked region it is configured to not allow future changes to these properties.
