Tony Luck 12e0110c11 x86/intel_rdt: Add cpus file ... Now we populate each directory with a read/write (mode 0644) file named "cpus". This is used to over-ride the resources available to processes in the default resource group when running on specific CPUs. Each "cpus" file reads as a cpumask showing which CPUs belong to this resource group. Initially all online CPUs are assigned to the default group. They can be added to other groups by writing a cpumask to the "cpus" file in the directory for the resource group (which will remove them from the previous group to which they were assigned). CPU online/offline operations will delete CPUs that go offline from whatever group they are in and add new CPUs to the default group. If there are CPUs assigned to a group when the directory is removed, they are returned to the default group.
