An array of sub-classes of this type will be returned by Linux::Cpuinfo.cpus


It provides an interface to the information provided by the kernel with generated
accessor methods for each of the fields.


Linux::Cpuinfo::Cpu - per cpu core information.


NAME

DESCRIPTION

The below is a list of fields that I found when I first documented the Perl 5
version of this module, the actual methods present will be generated at run-time
from the field names found in the /proc/cpuinfo so will almost certainly differ.


The full list can be discovered by calling C<.fields.keys> on the object.


This is the index of the processor this information is for, it will be zero
for a the first CPU (which is the only one on single-proccessor systems), one
for the second and so on.


This is a vendor defined string for X86 CPUs such as 'GenuineIntel' or
'AuthenticAMD'. 12 bytes long, since it is returned via three 32 byte long
registers.


This should return an integer that will indicate the 'family' of the 
processor - This is for instance '6' for a Pentium III. Might be undefined for
non-X86 CPUs.


An integer that is probably vendor dependent that indicates their version 
of the above cpu_family


A string such as 'Pentium III (Coppermine)'.


I'm lead to believe this is a version increment used by intel.


I guess this is self explanatory - it might however be different to what
it says on the box. The Mhz is measured at boot time by the kernel and
represents the true Mhz at that time.


The cache size for this processor - it might well have the units appended
( such as 'KB' )


True if this bug is present in the processor.


True if the CPU has a floating point unit.


True if the floating point unit can throw an exception.


The C<cpuid> assembler instruction is only present on X86 CPUs. This attribute
represents the level of the instruction that is supported by the CPU. The first
CPUs had only level 1, newer chips have more levels and can thus return more
information.


This is the set of flags that the CPU supports - this is returned as an
array


The byte order of the CPU, might be little endian or big endian, or undefined
for unknown.


A system constant calculated when the kernel is booted - it is a (rather poor)
measure of the CPU's performance.

README

On Linux systems various information about the CPU ( or CPUs ) in the
computer can be gleaned from C</proc/cpuinfo>. This module provides an
object oriented interface to that information for relatively simple use
in Raku programs.
