Linux::Sysfs::Driver - sysfs drivers
my $driver = Linux::Sysfs::Driver->open('pci', 'tg3'); my @attrs = $driver->get_attrs; my @devices = $driver->get_devices; $driver->close;
Drivers are represented in sysfs under the /sys/bus/xxx/drivers (xxx being the bus type, such as "pci", "usb, and so on).
my $driver = Linux::Sysfs::Driver->open($bus_name, $name);
Given the name of the bus,
$bus_name, on which to look for, this method locates a given driver and returns a Linux::Sysfs::Driver instance corresponding to the requested device or undef, if no matching driver was found.
my $driver = Linux::Sysfs::Driver->open_path($path);
Opens driver at specific
$path. Returns a Linux::Sysfs::Driver instance on success or undef on failure.
Closes and cleans up
my $attr = $driver->get_attribute($name);
$driver's attributes by
$name and returns the corresponding Linux::Sysfs::Attribute instance or undef, of no matching attribute was found.
my @attrs = $driver->get_attributes;
$driver and returns a list of Linux::Sysfs::Attribute instances for the driver.
my @devices = $driver->get_devices;
Returns a list of Linux::Sysfs::Device instances that use this
my $module = $driver->get_module;
Returns the module that the
$driver is using.
my $name = $driver->name;
my $path = $driver->path;
$driver's full path in sysfs.
my $bus_name = $driver->bus;
Returns the name of the bus on which the
$device is registered.
