- 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.

- Software mechanism to pin data in a cache portion using
- micro-architecture specific knowledge.
- config RESCTRL_RMID_DEPENDS_ON_CLOSID
- bool
- depends on RESCTRL_FS
- help
- Enabled by the architecture when the RMID values depend on the CLOSID.
- This causes the CLOSID allocator to search for CLOSID with clean
- RMID.
