2 How CPU topology info is exported via sysfs
5 Export CPU topology info via sysfs. Items (attributes) are similar
7 /sys/devices/system/cpu/cpuX/topology/:
17 the CPU die ID of cpuX. Typically it is the hardware platform's
23 the CPU core ID of cpuX. Typically it is the hardware platform's
41 internal kernel map of CPUs within the same core.
46 human-readable list of CPUs within the same core.
56 human-readable list of CPUs sharing the same physical_package_id.
65 human-readable list of CPUs within the same die.
74 human-readable list of cpuX's hardware threads within the same
84 human-readable list of cpuX's hardware threads within the same
87 Architecture-neutral, drivers/base/topology.c, exports these attributes.
92 where they reflect the cpu and cache hierarchy.
95 these macros in include/asm-XXX/topology.h::

115 not defined by include/asm-XXX/topology.h:
117 1) topology_physical_package_id: -1
118 2) topology_die_id: -1
120 4) topology_sibling_cpumask: just the given CPU
121 5) topology_core_cpumask: just the given CPU
122 6) topology_die_cpumask: just the given CPU
129 Additionally, CPU topology information is provided under
130 /sys/devices/system/cpu and includes these files. The internal
134 kernel_max: the maximum CPU index allowed by the kernel configuration.

138 HOTPLUGGED off (see cpu-hotplug.txt) or exceed the limit
154 In this example, there are 64 CPUs in the system but cpus 32-63 exceed
156 being 32. Note also that CPUs 2 and 4-31 are not online but could be
160 offline: 2,4-31,32-63
