The following is a random collection of documentation regarding
network devices.
struct net_device allocation rules
==================================
struct net_device lifetime rules
================================
Network device structures need to persist even after module is unloaded and
must be allocated with alloc_netdev_mqs() and friends.
If device has registered successfully, it will be freed on last use
by free_netdev(). This is required to handle the pathologic case cleanly
(example: rmmod mydriver </sys/class/net/myeth/mtu )
by free_netdev(). This is required to handle the pathological case cleanly
(example: ``rmmod mydriver </sys/class/net/myeth/mtu``)
alloc_netdev_mqs()/alloc_netdev() reserve extra space for driver
alloc_netdev_mqs() / alloc_netdev() reserve extra space for driver
private data which gets freed when the network device is freed. If
separately allocated data is attached to the network device
(netdev_priv(dev)) then it is up to the module exit handler to free that.
(netdev_priv()) then it is up to the module exit handler to free that.
There are two groups of APIs for registering struct net_device.
First group can be used in normal contexts where ``rtnl_lock`` is not already
held: register_netdev(), unregister_netdev().
Second group can be used when ``rtnl_lock`` is already held:
register_netdevice(), unregister_netdevice(), free_netdevice().
Simple drivers
--------------
Most drivers (especially device drivers) handle lifetime of struct net_device
in context where ``rtnl_lock`` is not held (e.g. driver probe and remove paths).
In that case the struct net_device registration is done using
the register_netdev(), and unregister_netdev() functions:
.. code-block:: c
int probe()
{
struct my_device_priv *priv;
int err;
dev = alloc_netdev_mqs(...);
if (!dev)
return -ENOMEM;
priv = netdev_priv(dev);
/* ... do all device setup before calling register_netdev() ...
*/
err = register_netdev(dev);
if (err)
goto err_undo;
/* net_device is visible to the user! */
err_undo:
/* ... undo the device setup ... */
free_netdev(dev);
return err;
}
void remove()
{
unregister_netdev(dev);
free_netdev(dev);
}
Note that after calling register_netdev() the device is visible in the system.
Users can open it and start sending / receiving traffic immediately,
or run any other callback, so all initialization must be done prior to
registration.
unregister_netdev() closes the device and waits for all users to be done
with it. The memory of struct net_device itself may still be referenced
by sysfs but all operations on that device will fail.
free_netdev() can be called after unregister_netdev() returns on when
register_netdev() failed.
Device management under RTNL
----------------------------
Registering struct net_device while in context which already holds
the ``rtnl_lock`` requires extra care. In those scenarios most drivers
will want to make use of struct net_device's ``needs_free_netdev``
and ``priv_destructor`` members for freeing of state.
Example flow of netdev handling under ``rtnl_lock``:
.. code-block:: c
static void my_setup(struct net_device *dev)
{
dev->needs_free_netdev = true;
}
static void my_destructor(struct net_device *dev)
{
some_obj_destroy(priv->obj);
some_uninit(priv);
}
int create_link()
{
struct my_device_priv *priv;
int err;
ASSERT_RTNL();
dev = alloc_netdev(sizeof(*priv), "net%d", NET_NAME_UNKNOWN, my_setup);
if (!dev)
return -ENOMEM;
priv = netdev_priv(dev);
/* Implicit constructor */
err = some_init(priv);
if (err)
goto err_free_dev;
priv->obj = some_obj_create();
if (!priv->obj) {
err = -ENOMEM;
goto err_some_uninit;
}
/* End of constructor, set the destructor: */
dev->priv_destructor = my_destructor;
err = register_netdevice(dev);
if (err)
/* register_netdevice() calls destructor on failure */
goto err_free_dev;
/* If anything fails now unregister_netdevice() (or unregister_netdev())
* will take care of calling my_destructor and free_netdev().
*/
return 0;
err_some_uninit:
some_uninit(priv);
err_free_dev:
free_netdev(dev);
return err;
}
If struct net_device.priv_destructor is set it will be called by the core
some time after unregister_netdevice(), it will also be called if
register_netdevice() fails. The callback may be invoked with or without
``rtnl_lock`` held.
There is no explicit constructor callback, driver "constructs" the private
netdev state after allocating it and before registration.
Setting struct net_device.needs_free_netdev makes core call free_netdevice()
automatically after unregister_netdevice() when all references to the device
are gone. It only takes effect after a successful call to register_netdevice()
so if register_netdevice() fails driver is responsible for calling
free_netdev().
free_netdev() is safe to call on error paths right after unregister_netdevice()
or when register_netdevice() fails. Parts of netdev (de)registration process
happen after ``rtnl_lock`` is released, therefore in those cases free_netdev()
will defer some of the processing until ``rtnl_lock`` is released.
Devices spawned from struct rtnl_link_ops should never free the
struct net_device directly.
.ndo_init and .ndo_uninit
~~~~~~~~~~~~~~~~~~~~~~~~~
``.ndo_init`` and ``.ndo_uninit`` callbacks are called during net_device
registration and de-registration, under ``rtnl_lock``. Drivers can use
those e.g. when parts of their init process need to run under ``rtnl_lock``.
``.ndo_init`` runs before device is visible in the system, ``.ndo_uninit``
runs during de-registering after device is closed but other subsystems
may still have outstanding references to the netdevice.

============================
ALSA Jack Software Injection
============================
Simple Introduction On Jack Injection
=====================================
Here jack injection means users could inject plugin or plugout events
to the audio jacks through debugfs interface, it is helpful to
validate ALSA userspace changes. For example, we change the audio
profile switching code in the pulseaudio, and we want to verify if the
change works as expected and if the change introduce the regression,
in this case, we could inject plugin or plugout events to an audio
jack or to some audio jacks, we don't need to physically access the
machine and plug/unplug physical devices to the audio jack.
In this design, an audio jack doesn't equal to a physical audio jack.
Sometimes a physical audio jack contains multi functions, and the
ALSA driver creates multi ``jack_kctl`` for a ``snd_jack``, here the
``snd_jack`` represents a physical audio jack and the ``jack_kctl``
represents a function, for example a physical jack has two functions:
headphone and mic_in, the ALSA ASoC driver will build 2 ``jack_kctl``
for this jack. The jack injection is implemented based on the
``jack_kctl`` instead of ``snd_jack``.
To inject events to audio jacks, we need to enable the jack injection
via ``sw_inject_enable`` first, once it is enabled, this jack will not
change the state by hardware events anymore, we could inject plugin or
plugout events via ``jackin_inject`` and check the jack state via
``status``, after we finish our test, we need to disable the jack
injection via ``sw_inject_enable`` too, once it is disabled, the jack
state will be restored according to the last reported hardware events
and will change by future hardware events.
The Layout of Jack Injection Interface
======================================
If users enable the SND_JACK_INJECTION_DEBUG in the kernel, the audio
jack injection interface will be created as below:
