| Some architectures provide hardware facilities to group tasks and | |
| monitor and control their usage of memory system resources such as | |
| caches and memory bandwidth. Examples of such facilities include | |
| Intel's Resource Director Technology (Intel(R) RDT) and AMD's | |
| Platform Quality of Service (AMD QoS). | |
| If your system has the necessary support and you want to be able to | |
| assign tasks to groups and manipulate the associated resource | |
| monitors and controls from userspace, say Y here to get a mountable | |
| 'resctrl' filesystem that lets you do just that. | |
| If nothing mounts or prods the 'resctrl' filesystem, resource | |
| controls and monitors are left in a quiescent, permissive state. | |
| On architectures where this can be disabled independently, it is | |
| safe to say N. | |
| See <file:Documentation/filesystems/resctrl.rst> for more information. | |
