2 How CPU topology info is exported via sysfs
5 CPU topology info is exported via sysfs. Items (attributes) are similar
7 /sys/devices/system/cpu/cpuX/topology/. Please refer to the ABI file:
8 Documentation/ABI/stable/sysfs-devices-system-cpu.
10 Architecture-neutral, drivers/base/topology.c, exports these attributes.
16 these macros in include/asm-XXX/topology.h::
18 	#define topology_physical_package_id(cpu)
19 	#define topology_die_id(cpu)
20 	#define topology_cluster_id(cpu)
21 	#define topology_core_id(cpu)
22 	#define topology_book_id(cpu)

53 Additionally, CPU topology information is provided under
54 /sys/devices/system/cpu and includes these files.  The internal
58     kernel_max: the maximum CPU index allowed by the kernel configuration.

78 In this example, there are 64 CPUs in the system but cpus 32-63 exceed
80 being 32.  Note also that CPUs 2 and 4-31 are not online but could be
84         offline: 2,4-31,32-63
85          online: 0-1,3

91 was manually taken offline (and is the only CPU that can be brought
