From: Fenghua Yu <[email protected]>
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
