Description: CPU topology files that describe a logical CPU's relationship
to other cores and threads in the same physical package.
- One cpu# directory is created per logical CPU in the system,
+ One cpuX directory is created per logical CPU in the system,
e.g. /sys/devices/system/cpu/cpu42/.
Briefly, the files above are:
- core_id: the CPU core ID of cpu#. Typically it is the
+ core_id: 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.
- core_siblings: internal kernel map of cpu#'s hardware threads
+ core_siblings: internal kernel map of cpuX's hardware threads
within the same physical_package_id.
core_siblings_list: human-readable list of the logical CPU
- numbers within the same physical_package_id as cpu#.
+ numbers within the same physical_package_id as cpuX.
- physical_package_id: physical package id of cpu#. Typically
+ physical_package_id: physical package id of cpuX. Typically
corresponds to a physical socket number, but the actual value
is architecture and platform dependent.
- thread_siblings: internal kernel map of cpu#'s hardware
- threads within the same core as cpu#
+ thread_siblings: internal kernel map of cpuX's hardware
+ threads within the same core as cpuX
- thread_siblings_list: human-readable list of cpu#'s hardware
