Subject: [PATCH 0/2][v2] Add task resctrl information in procfs
Date: Fri, 15 Nov 2019 13:23:40 +0800 [thread overview]
Message-ID: <cover.1573788882.git.yu.c.chen@intel.com> (raw)
Expose the resctrl information in /proc/{pid}/resctrl
so that the user space tool is able to locate the resctrl
directory path in O(1) rather than O(n) - n is the number
of tasks in the system.
