NAME
Linux::Info::SysInfo::CPU::Arm - Collects Arm based CPU information from /proc/cpuinfo
VERSION
version 2.18
SYNOPSIS
See Linux::Info::SysInfo get_cpu method.
DESCRIPTION
This is a subclass of Linux::Info::SysInfo::CPU, with specific code to parse ARM format of "proc/cpuinfo".
Finding information about a ARM processor can be quite difficult. Not all vendors have model information available on the "proc/cpuinfo" file, and sometimes is required to even search specifications for a processor using the following attributes in this class:
vendor(or "CPU implementer" in the original source file)variantpartrevision
Most probably those values will be only hexadecimals that you will need to search for.
This module does it best to correlate the vendor with a human readable text, but this is limited, and in cases it fails, vendor will filled with original hexadecimal for "CPU implementer" and a warn will be generated.
One good source to search for more information is the OpenBenchmarking website.
METHODS
processor_regex
Returns a regular expression that identifies the processor that is being read.
get_cores
Returns the number of cores of the processor.
get_threads
Returns the number of threads of the processor.
get_part
Return an hexadecimal of the CPU part.
get_revision
Return an hexadecimal of the CPU revision.
get_variant
Return an hexadecimal of the CPU variant.
