       During context switches, the supervisor may choose to execute with the `srmcfg` of the outgoing context to attribute the execution to it.
       Prior to restoring the new context, it switches to the new VM’s `srmcfg`.
       The supervisor can also use a separate configuration for execution not to be attributed to either context.
