NAME ^

Linux::Sysfs::Bus - sysfs buses

SYNOPSIS ^

        my $bus = Linux::Sysfs::Bus->open('pci');

        my @devices = $bus->get_devices;
        my @drivers = $bus->get_drivers;

        $bus->close;

DESCRIPTION ^

The library provides functions for viewing buses represented in sysfs.

METHODS ^

open
        my $bus = Linux::Sysfs::Bus->open($name);

Opens up one of the buses represented in sysfs in the /sys/bus directory. $name is the name of the bus to open (e.g. "pci"). It returns a Linux::Sysfs::Bus instance on success or undef on failure.

close
        $bus->close;

Closes up the sysfs_bus structure including its devices, and drivers and the list of attributes.

get_devices
        my @devices = $bus->get_devices;

Returns a list of Linux::Sysfs::Device instances that are registered with this bus.

get_drivers
        my @drivers = $bus->get_drivers;

Returns a list of Linux::Sysfs::Driver instances that are registered with this bus.

get_device
        my $device = $bus->get_device($id);

Looks for a device with the given $id on this bus. On success, it returns a Linux::Sysfs::Device instance, otherwise undef.

get_driver
        my $driver = $bus->get_driver($name);

Looks for a driver with the given $name on this bus. On success, it returns a Linux::Sysfs::Driver instance, otherwise undef.

name
        my $name = $bus->name;

Returns the bus' name.

path
        my $path = $attr->path;
