Subject[PATCH v2 23/33] x86/intel_rdt_rdtgroup.c: User interface for RDT
Date
From: Fenghua Yu <fenghua.yu@intel.com>

We introduce a new resctrl file system mounted under /sys/fs/resctrl.
User uses this file system to control resource allocation.

Hiearchy of the file system is as follows:
/sys/fs/resctrl/info/info
/<resource0>/<resource0 specific info files>
/<resource1>/<resource1 specific info files>
....
/tasks
/cpus
/schemata
/sub-dir1
/sub-dir2
....

User can specify which task uses which schemata for resource allocation.

More details can be found in Documentation/x86/intel_rdt_ui.txt
