PHY Abstraction Layer
(Updated 2005-07-21)
Purpose
Most network devices consist of set of registers which provide an interface
to a MAC layer, which communicates with the physical connection through a
PHY. The PHY concerns itself with negotiating link parameters with the link
partner on the other side of the network connection (typically, an ethernet
cable), and provides a register interface to allow drivers to determine what
settings were chosen, and to configure what settings are allowed.
While these devices are distinct from the network devices, and conform to a
standard layout for the registers, it has been common practice to integrate
the PHY management code with the network driver. This has resulted in large
amounts of redundant code. Also, on embedded systems with multiple (and
sometimes quite different) ethernet controllers connected to the same
management bus, it is difficult to ensure safe use of the bus.
Since the PHYs are devices, and the management busses through which they are
accessed are, in fact, busses, the PHY Abstraction Layer treats them as such.
In doing so, it has these goals:
1) Increase code-reuse
2) Increase overall code-maintainability
3) Speed development time for new network drivers, and for new systems
Basically, this layer is meant to provide an interface to PHY devices which
allows network driver writers to write as little code as possible, while
still providing a full feature set.
The MDIO bus
Most network devices are connected to a PHY by means of a management bus.
Different devices use different busses (though some share common interfaces).
In order to take advantage of the PAL, each bus interface needs to be
registered as a distinct device.
1) read and write functions must be implemented. Their prototypes are:
int write(struct mii_bus *bus, int mii_id, int regnum, u16 value);
int read(struct mii_bus *bus, int mii_id, int regnum);
mii_id is the address on the bus for the PHY, and regnum is the register
number. These functions are guaranteed not to be called from interrupt
time, so it is safe for them to block, waiting for an interrupt to signal
the operation is complete
2) A reset function is necessary. This is used to return the bus to an
initialized state.
3) A probe function is needed. This function should set up anything the bus
driver needs, setup the mii_bus structure, and register with the PAL using
mdiobus_register. Similarly, there's a remove function to undo all of
that (use mdiobus_unregister).
4) Like any driver, the device_driver structure must be configured, and init
exit functions are used to register the driver.
5) The bus must also be declared somewhere as a device, and registered.
As an example for how one driver implemented an mdio bus driver, see
drivers/net/gianfar_mii.c and arch/ppc/syslib/mpc85xx_devices.c
Connecting to a PHY
Sometime during startup, the network driver needs to establish a connection
between the PHY device, and the network device. At this time, the PHY's bus
and drivers need to all have been loaded, so it is ready for the connection.
At this point, there are several ways to connect to the PHY:
1) The PAL handles everything, and only calls the network driver when
the link state changes, so it can react.
2) The PAL handles everything except interrupts (usually because the
controller has the interrupt registers).
3) The PAL handles everything, but checks in with the driver every second,
allowing the network driver to react first to any changes before the PAL
does.
4) The PAL serves only as a library of functions, with the network device
manually calling functions to update status, and configure the PHY
Letting the PHY Abstraction Layer do Everything
If you choose option 1 (The hope is that every driver can, but to still be
useful to drivers that can't), connecting to the PHY is simple:
First, you need a function to react to changes in the link state. This
function follows this protocol:
static void adjust_link(struct net_device *dev);
Next, you need to know the device name of the PHY connected to this device.
The name will look something like, "phy0:0", where the first number is the
bus id, and the second is the PHY's address on that bus.
Now, to connect, just call this function:
phydev = phy_connect(dev, phy_name, &adjust_link, flags);
phydev is a pointer to the phy_device structure which represents the PHY. If
phy_connect is successful, it will return the pointer. dev, here, is the
pointer to your net_device. Once done, this function will have started the
PHY's software state machine, and registered for the PHY's interrupt, if it
has one. The phydev structure will be populated with information about the
current state, though the PHY will not yet be truly operational at this
point.
flags is a u32 which can optionally contain phy-specific flags.
This is useful if the system has put hardware restrictions on
the PHY/controller, of which the PHY needs to be aware.
Now just make sure that phydev->supported and phydev->advertising have any
values pruned from them which don't make sense for your controller (a 10/100
controller may be connected to a gigabit capable PHY, so you would need to
mask off SUPPORTED_1000baseT*). See include/linux/ethtool.h for definitions
for these bitfields. Note that you should not SET any bits, or the PHY may
get put into an unsupported state.
Lastly, once the controller is ready to handle network traffic, you call
phy_start(phydev). This tells the PAL that you are ready, and configures the
PHY to connect to the network. If you want to handle your own interrupts,
just set phydev->irq to PHY_IGNORE_INTERRUPT before you call phy_start.
Similarly, if you don't want to use interrupts, set phydev->irq to PHY_POLL.
When you want to disconnect from the network (even if just briefly), you call
phy_stop(phydev).
Keeping Close Tabs on the PAL
It is possible that the PAL's built-in state machine needs a little help to
keep your network device and the PHY properly in sync. If so, you can
register a helper function when connecting to the PHY, which will be called
every second before the state machine reacts to any changes. To do this, you
need to manually call phy_attach() and phy_prepare_link(), and then call
phy_start_machine() with the second argument set to point to your special
handler.
Currently there are no examples of how to use this functionality, and testing
on it has been limited because the author does not have any drivers which use
it (they all use option 1). So Caveat Emptor.
Doing it all yourself
There's a remote chance that the PAL's built-in state machine cannot track
the complex interactions between the PHY and your network device. If this is
so, you can simply call phy_attach(), and not call phy_start_machine or
phy_prepare_link(). This will mean that phydev->state is entirely yours to
handle (phy_start and phy_stop toggle between some of the states, so you
might need to avoid them).
An effort has been made to make sure that useful functionality can be
accessed without the state-machine running, and most of these functions are
descended from functions which did not interact with a complex state-machine.
However, again, no effort has been made so far to test running without the
state machine, so tryer beware.
Here is a brief rundown of the functions:
int phy_read(struct phy_device *phydev, u16 regnum);
int phy_write(struct phy_device *phydev, u16 regnum, u16 val);
Simple read/write primitives. They invoke the bus's read/write function
pointers.
void phy_print_status(struct phy_device *phydev);
A convenience function to print out the PHY status neatly.
int phy_clear_interrupt(struct phy_device *phydev);
int phy_config_interrupt(struct phy_device *phydev, u32 interrupts);
Clear the PHY's interrupt, and configure which ones are allowed,
respectively. Currently only supports all on, or all off.
int phy_enable_interrupts(struct phy_device *phydev);
int phy_disable_interrupts(struct phy_device *phydev);
Functions which enable/disable PHY interrupts, clearing them
before and after, respectively.
int phy_start_interrupts(struct phy_device *phydev);
int phy_stop_interrupts(struct phy_device *phydev);
Requests the IRQ for the PHY interrupts, then enables them for
start, or disables then frees them for stop.
struct phy_device * phy_attach(struct net_device *dev, const char *phy_id,
u32 flags);
Attaches a network device to a particular PHY, binding the PHY to a generic
driver if none was found during bus initialization. Passes in
any phy-specific flags as needed.
int phy_start_aneg(struct phy_device *phydev);
Using variables inside the phydev structure, either configures advertising
and resets autonegotiation, or disables autonegotiation, and configures
forced settings.
static inline int phy_read_status(struct phy_device *phydev);
Fills the phydev structure with up-to-date information about the current
settings in the PHY.
void phy_sanitize_settings(struct phy_device *phydev)
Resolves differences between currently desired settings, and
supported settings for the given PHY device. Does not make
the changes in the hardware, though.
int phy_ethtool_sset(struct phy_device *phydev, struct ethtool_cmd *cmd);
int phy_ethtool_gset(struct phy_device *phydev, struct ethtool_cmd *cmd);
Ethtool convenience functions.
int phy_mii_ioctl(struct phy_device *phydev,
struct mii_ioctl_data *mii_data, int cmd);
The MII ioctl. Note that this function will completely screw up the state
machine if you write registers like BMCR, BMSR, ADVERTISE, etc. Best to
use this only to write registers which are not standard, and don't set off
a renegotiation.
PHY Device Drivers
With the PHY Abstraction Layer, adding support for new PHYs is
quite easy. In some cases, no work is required at all! However,
many PHYs require a little hand-holding to get up-and-running.
Generic PHY driver
If the desired PHY doesn't have any errata, quirks, or special
features you want to support, then it may be best to not add
support, and let the PHY Abstraction Layer's Generic PHY Driver
do all of the work.
Writing a PHY driver
If you do need to write a PHY driver, the first thing to do is
make sure it can be matched with an appropriate PHY device.
This is done during bus initialization by reading the device's
UID (stored in registers 2 and 3), then comparing it to each
driver's phy_id field by ANDing it with each driver's
phy_id_mask field. Also, it needs a name. Here's an example:
static struct phy_driver dm9161_driver = {
.phy_id = 0x0181b880,
.name = "Davicom DM9161E",
.phy_id_mask = 0x0ffffff0,
...
}
Next, you need to specify what features (speed, duplex, autoneg,
etc) your PHY device and driver support. Most PHYs support
PHY_BASIC_FEATURES, but you can look in include/mii.h for other
features.
Each driver consists of a number of function pointers:
config_init: configures PHY into a sane state after a reset.
For instance, a Davicom PHY requires descrambling disabled.
probe: Does any setup needed by the driver
suspend/resume: power management
config_aneg: Changes the speed/duplex/negotiation settings
read_status: Reads the current speed/duplex/negotiation settings
ack_interrupt: Clear a pending interrupt
config_intr: Enable or disable interrupts
remove: Does any driver take-down
Of these, only config_aneg and read_status are required to be
assigned by the driver code. The rest are optional. Also, it is
preferred to use the generic phy driver's versions of these two
functions if at all possible: genphy_read_status and
genphy_config_aneg. If this is not possible, it is likely that
you only need to perform some actions before and after invoking
these functions, and so your functions will wrap the generic
ones.
Feel free to look at the Marvell, Cicada, and Davicom drivers in
drivers/net/phy/ for examples (the lxt and qsemi drivers have
not been tested as of this writing)

This driver does not support the TI 4000M TravelMate and the ACER

desktop machines also don't have compliant BIOSes, and this driver
may cause those machines to panic during the boot phase.
Generally, if you don't have a battery in your machine, there isn't
much point in using this driver and you should say N. If you get
random kernel OOPSes or reboots that don't seem to be related to
anything, try disabling/enabling this option (or disabling/enabling
APM in your BIOS).
Some other things you should try when experiencing seemingly random,
"weird" problems:
1) make sure that you have enough swap space and that it is
enabled.
2) pass the "no-hlt" option to the kernel
3) switch on floating point emulation in the kernel and pass
the "no387" option to the kernel
4) pass the "floppy=nodma" option to the kernel
5) pass the "mem=4M" option to the kernel (thereby disabling
all but the first 4 MB of RAM)
6) make sure that the CPU is not over clocked.
7) read the sig11 FAQ at <http://www.bitwizard.nl/sig11/>
