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) diff --git a/drivers/net/Kconfig b/drivers/net/Kconfig index 8a835eb58808..1e50b8e32add 100644 --- a/drivers/net/Kconfig +++ b/drivers/net/Kconfig @@ -131,6 +131,8 @@ config NET_SB1000 source "drivers/net/arcnet/Kconfig" +source "drivers/net/phy/Kconfig" + # # Ethernet # diff --git a/drivers/net/Makefile b/drivers/net/Makefile index 63c6d1e6d4d9..a369ae284a9a 100644 --- a/drivers/net/Makefile +++ b/drivers/net/Makefile @@ -65,6 +65,7 @@ obj-$(CONFIG_ADAPTEC_STARFIRE) += starfire.o # obj-$(CONFIG_MII) += mii.o +obj-$(CONFIG_PHYLIB) += phy/ obj-$(CONFIG_SUNDANCE) += sundance.o obj-$(CONFIG_HAMACHI) += hamachi.o diff --git a/drivers/net/phy/Kconfig b/drivers/net/phy/Kconfig new file mode 100644 index 000000000000..8b5db2343cc3 --- /dev/null +++ b/drivers/net/phy/Kconfig @@ -0,0 +1,57 @@ +# +# PHY Layer Configuration +# + +menu "PHY device support" + +config PHYLIB + bool "PHY Device support and infrastructure" + depends on NET_ETHERNET + help + Ethernet controllers are usually attached to PHY + devices.

This is because libata interrupt handler is unaware that interrupts are not expected during that period. This patch adds ATA_FLAG_NOINTR flag to tell the interrupt handler that we're not expecting interrupts. Note that once proper HSM is implemented for interrupt-driven PIO, this should be merged into it and this flag will be removed. ahci.c is a different kind of beast, so it's left alone. * The following drivers use ata_qc_issue_prot and ata_interrupt, so changes in libata core will do. ata_piix sata_sil sata_svw sata_via sata_sis sata_uli * The following drivers use ata_qc_issue_prot and custom intr handler.

Since mod_devicetable.h is included both from kernel and from host build helper, we may be in trouble if we are building on 32bit host for 64bit target - userland sees unsigned long long, kernel sees unsigned long and while their sizes match, alignments might not. Fixed by forcing alignment. Fortunately, almost nobody else needs that - the rest of such fields is naturally aligned as it is. * of_device_id has void * in it. Host userland helpers need kernel_ulong_t instead, since their void * might have nothing to do with the kernel one. Fixed in the same way it's done for similar problems in pcmcia_device_id (ifdef __KERNEL__). * pcmcia_device_id has the same problem as ieee1394_device_id. Fixed the same way.

Miller" Date: Mon, 29 Aug 2005 12:45:11 -0700 Subject: [SPARC64]: Revamp Spitfire error trap handling. Current uncorrectable error handling was poor enough that the processor could just loop taking the same trap over and over again. Fix things up so that we at least get a log message and perhaps even some register state. In the process, much consolidation became possible, particularly with the correctable error handler. Prefix assembler and C function names with "spitfire" to indicate that these are for Ultra-I/II/IIi/IIe only. More work is needed to make these routines robust and featureful to the level of the Ultra-III error handlers. Signed-off-by: David S.

When the spinlock routines were moved out of line into kernel/spinlock.c this made it so that the debugging spinlocks record lock acquisition program counts in the kernel/spinlock.c functions not in their callers. This makes the debugging info kind of useless. So record the correct caller's program counter and now this feature is useful once more. Signed-off-by: David S.

Miller" Date: Mon, 29 Aug 2005 12:46:22 -0700 Subject: [SPARC64]: More fully work around Spitfire Errata 51. It appears that a memory barrier soon after a mispredicted branch, not just in the delay slot, can cause the hang condition of this cpu errata. So move them out-of-line, and explicitly put them into a "branch always, predict taken" delay slot which should fully kill this problem. Signed-off-by: David S.
