NAME
Linux::Proc::Cpuinfo - XS wrapper for libproccpuinfo - a generic parser
for /proc/cpuinfo
SYNOPSIS
use Linux::Proc::Cpuinfo;
my $info = Linux::Proc::Cpuinfo->new;
if ( defined $info ) {
print "Architecture:\t\t", $info->architecture, "\n";
print "Hardware Platform:\t", $info->hardware_platform, "\n";
print "Frequency:\t\t", $info->frequency, "\n";
print "Bogomips:\t\t", $info->bogomips, "\n";
print "Cache:\t\t\t", $info->cache, "\n";
print "CPUs:\t\t\t", $info->cpus, "\n";
}
DESCRIPTION
Linux::Proc::Cpuinfo is a XS wrapper for "libproccpuinfo"
(<https://savannah.nongnu.org/projects/proccpuinfo/>). It provides a
generic interface to access "/proc/cpuinfo".
METHODS
"new" or "new('filename')"
Returns a new Linux::Proc::Cpuinfo object. Without any argument, parses
"/proc/cpuinfo". If "filename" is passed, then the file with that name
is parsed.
On error, returns "undef".
"architecture"
Returns CPU architecture. If "/proc/cpuinfo" file does not list these
values or if the library fails to recognise the architecture, then the
value will be set to "undef".
"hardware_platform"
Returns hardware platform. If "/proc/cpuinfo" file does not list these
values or if the library fails to recognise the hardware platform, then
the value will be set to "undef".
"frequency"
Returns the CPU clock speed in MHz. If the "/proc/cpuinfo" file does not
list the clock speed or if the library fails to recognise the clock
speed, then this value defaults to "undef".
"bogomips"
Returns the BogoMips as calculated by the kernel. BogoMips defaults to
"undef" if the "/proc/cpuinfo" file does not list the BogoMips or if the
library fails to recognise the BogoMips.
"cache"
Returns the amount of L2 cache in kilobytes. If the "/proc/cpuinfo" file
does not list the amount of L2 cache or if the library fails to
recognise the amount of L2 cache, then the value defaults to "undef".
"cpus"
Returns the total number of processors detected. On systems that list
the number of detected processors and the number of active/enabled
processors, the number of detected processors is used. If the
"/proc/cpuinfo" file does not list the number of processors or if the
library fails to determine the number of processors, then the value
defaults to 1 since all running computers have at least 1 processor.
INSTALLING "libproccpuinfo"
* Gentoo Linux
# emerge libproccpuinfo
* Generic Linux
Download the latest archive (named similar to
"libproccpuinfo-x.x.x.tar.bz2") from
<http://download.savannah.gnu.org/releases/proccpuinfo/> and extract
it.
$ cmake -D CMAKE_INSTALL_PREFIX=/usr .
$ make
$ make test
# make install
Please send me information on how to install it on other systems and
I will update it here.
