+What: /sys/devices/system/cpu/dscr_default
+Date: 13-May-2014
+KernelVersion: v3.15.0
+Contact:
+Description: Writes are equivalent to writing to
+ /sys/devices/system/cpu/cpuN/dscr on all CPUs.
+ Reads return the last written value or 0.
+ This value is not a global default: it is a way to set
+ all per-CPU defaults at the same time.
+Values: 64 bit unsigned integer (bit field)
+
+What: /sys/devices/system/cpu/cpu[0-9]+/dscr
+Date: 13-May-2014
+KernelVersion: v3.15.0
+Contact:
+Description: Default value for the Data Stream Control Register (DSCR) on
+ a CPU.
+ This default value is used when the kernel is executing and
+ for any process that has not set the DSCR itself.
+ If a process ever sets the DSCR (via direct access to the
+ SPR) that value will be persisted for that process and used
+ on any CPU where it executes (overriding the value described
+ here).
+ If set by a process it will be inherited by child processes.
+Values: 64 bit unsigned integer (bit field)
+
+What: /sys/devices/system/cpu/cpuX/topology/physical_package_id
+Description: physical package id of cpuX. Typically corresponds to a physical
+ socket number, but the actual value is architecture and platform
+ dependent.
+Values: integer
+
+What: /sys/devices/system/cpu/cpuX/topology/die_id
+Description: the CPU die ID of cpuX. Typically it is the hardware platform's
+ identifier (rather than the kernel's). The actual value is
+ architecture and platform dependent.
+Values: integer
+
+What: /sys/devices/system/cpu/cpuX/topology/core_id
+Description: the CPU core ID of cpuX. Typically it is the hardware platform's
+ identifier (rather than the kernel's). The actual value is
+ architecture and platform dependent.
+Values: integer
+
+What: /sys/devices/system/cpu/cpuX/topology/cluster_id
+Description: the cluster ID of cpuX. Typically it is the hardware platform's
+ identifier (rather than the kernel's). The actual value is
+ architecture and platform dependent.
+Values: integer
+
+What: /sys/devices/system/cpu/cpuX/topology/book_id
+Description: the book ID of cpuX. Typically it is the hardware platform's
+ identifier (rather than the kernel's). The actual value is
+ architecture and platform dependent. it's only used on s390.
+Values: integer
+
+What: /sys/devices/system/cpu/cpuX/topology/drawer_id
+Description: the drawer ID of cpuX. Typically it is the hardware platform's
+ identifier (rather than the kernel's). The actual value is
+ architecture and platform dependent. it's only used on s390.
+Values: integer
+

+Description: human-readable list of CPUs within the same core.
+ The format is like 0-3, 8-11, 14,17.
+ (deprecated name: "thread_siblings_list").
+Values: decimal list.
+
