Device-Mapper Logging
=====================
The device-mapper logging code is used by some of the device-mapper
RAID targets to track regions of the disk that are not consistent.
A region (or portion of the address space) of the disk may be
inconsistent because a RAID stripe is currently being operated on or
a machine died while the region was being altered. In the case of
mirrors, a region would be considered dirty/inconsistent while you
are writing to it because the writes need to be replicated for all
the legs of the mirror and may not reach the legs at the same time.
Once all writes are complete, the region is considered clean again.
There is a generic logging interface that the device-mapper RAID
implementations use to perform logging operations (see
dm_dirty_log_type in include/linux/dm-dirty-log.h). Various different
logging implementations are available and provide different
capabilities. The list includes:
Type Files
==== =====
disk drivers/md/dm-log.c
core drivers/md/dm-log.c
userspace drivers/md/dm-log-userspace* include/linux/dm-log-userspace.h
The "disk" log type
-------------------
This log implementation commits the log state to disk. This way, the
logging state survives reboots/crashes.
The "core" log type
-------------------
This log implementation keeps the log state in memory. The log state
will not survive a reboot or crash, but there may be a small boost in
performance. This method can also be used if no storage device is
available for storing log state.
The "userspace" log type
------------------------
This log type simply provides a way to export the log API to userspace,
so log implementations can be done there. This is done by forwarding most
logging requests to userspace, where a daemon receives and processes the
request.
The structure used for communication between kernel and userspace are
located in include/linux/dm-log-userspace.h. Due to the frequency,
diversity, and 2-way communication nature of the exchanges between
kernel and userspace, 'connector' is used as the interface for
communication.
There are currently two userspace log implementations that leverage this
framework - "clustered_disk" and "clustered_core". These implementations
provide a cluster-coherent log for shared-storage. Device-mapper mirroring
can be used in a shared-storage environment when the cluster log implementations
are employed.

dm-service-time
===============
dm-service-time is a path selector module for device-mapper targets,
which selects a path with the shortest estimated service time for
the incoming I/O.
The service time for each path is estimated by dividing the total size
of in-flight I/Os on a path with the performance value of the path.
The performance value is a relative throughput value among all paths
in a path-group, and it can be specified as a table argument.
The path selector name is 'service-time'.
Table parameters for each path: [<repeat_count> [<relative_throughput>]]
<repeat_count>: The number of I/Os to dispatch using the selected
path before switching to the next path.
If not given, internal default is used. To check
the default value, see the activated table.
<relative_throughput>: The relative throughput value of the path
among all paths in the path-group.
The valid range is 0-100.
If not given, minimum value '1' is used.
If '0' is given, the path isn't selected while
other paths having a positive value are available.
Status for each path: <status> <fail-count> <in-flight-size> \
<relative_throughput>
<status>: 'A' if the path is active, 'F' if the path is failed.
<fail-count>: The number of path failures.
<in-flight-size>: The size of in-flight I/Os on the path.
<relative_throughput>: The relative throughput value of the path
among all paths in the path-group.
Algorithm
=========
dm-service-time adds the I/O size to 'in-flight-size' when the I/O is
dispatched and substracts when completed.
Basically, dm-service-time selects a path having minimum service time
which is calculated by:
('in-flight-size' + 'size-of-incoming-io') / 'relative_throughput'
However, some optimizations below are used to reduce the calculation
as much as possible.
1. If the paths have the same 'relative_throughput', skip
the division and just compare the 'in-flight-size'.
2. If the paths have the same 'in-flight-size', skip the division
and just compare the 'relative_throughput'.
3. If some paths have non-zero 'relative_throughput' and others
have zero 'relative_throughput', ignore those paths with zero
'relative_throughput'.
If such optimizations can't be applied, calculate service time, and
compare service time.
If calculated service time is equal, the path having maximum
'relative_throughput' may be better. So compare 'relative_throughput'
then.
Examples
========
In case that 2 paths (sda and sdb) are used with repeat_count == 128
and sda has an average throughput 1GB/s and sdb has 4GB/s,
'relative_throughput' value may be '1' for sda and '4' for sdb.
# echo "0 10 multipath 0 0 1 1 service-time 0 2 2 8:0 128 1 8:16 128 4" \
dmsetup create test
#
# dmsetup table
test: 0 10 multipath 0 0 1 1 service-time 0 2 2 8:0 128 1 8:16 128 4
#
# dmsetup status
test: 0 10 multipath 2 0 0 0 1 1 E 0 2 2 8:0 A 0 0 1 8:16 A 0 0 4
Or '2' for sda and '8' for sdb would be also true.
# echo "0 10 multipath 0 0 1 1 service-time 0 2 2 8:0 128 2 8:16 128 8" \
dmsetup create test

Once again, method 3 should be avoided wherever possible. Explicit device
instantiation (methods 1 and 2) is much preferred for it is safer and
faster.
Method 4: Instantiate from user-space
-------------------------------------
In general, the kernel should know which I2C devices are connected and
what addresses they live at. However, in certain cases, it does not, so a
sysfs interface was added to let the user provide the information. This
interface is made of 2 attribute files which are created in every I2C bus
directory: new_device and delete_device. Both files are write only and you
must write the right parameters to them in order to properly instantiate,
respectively delete, an I2C device.
File new_device takes 2 parameters: the name of the I2C device (a string)
and the address of the I2C device (a number, typically expressed in
hexadecimal starting with 0x, but can also be expressed in decimal.)
File delete_device takes a single parameter: the address of the I2C
device. As no two devices can live at the same address on a given I2C
segment, the address is sufficient to uniquely identify the device to be
deleted.
Example:
# echo eeprom 0x50 > /sys/class/i2c-adapter/i2c-3/new_device
While this interface should only be used when in-kernel device declaration
can't be done, there is a variety of cases where it can be helpful:
* The I2C driver usually detects devices (method 3 above) but the bus
segment your device lives on doesn't have the proper class bit set and
thus detection doesn't trigger.
* The I2C driver usually detects devices, but your device lives at an
unexpected address.
* The I2C driver usually detects devices, but your device is not detected,
either because the detection routine is too strict, or because your
device is not officially supported yet but you know it is compatible.
* You are developing a driver on a test board, where you soldered the I2C
device yourself.
This interface is a replacement for the force_* module parameters some I2C
drivers implement. Being implemented in i2c-core rather than in each
device driver individually, it is much more efficient, and also has the
advantage that you do not have to reload the driver to change a setting.
You can also instantiate the device before the driver is loaded or even
available, and you don't need to know what driver the device needs.

Accordingly, the I2C stack now has two models for associating I2C devices
with their drivers: the original "legacy" model, and a newer one that's
fully compatible with the Linux 2.6 driver model. These models do not mix,
since the "legacy" model requires drivers to create "i2c_client" device
objects after SMBus style probing, while the Linux driver model expects

Kernel driver lp3944
====================
* National Semiconductor LP3944 Fun-light Chip
Prefix: 'lp3944'
Addresses scanned: None (see the Notes section below)
Datasheet: Publicly available at the National Semiconductor website
http://www.national.com/pf/LP/LP3944.html
Authors:
Antonio Ospite <ospite@studenti.unina.it>
Description
-----------
The LP3944 is a helper chip that can drive up to 8 leds, with two programmable
DIM modes; it could even be used as a gpio expander but this driver assumes it
is used as a led controller.
The DIM modes are used to set _blink_ patterns for leds, the pattern is
specified supplying two parameters:
- period: from 0s to 1.6s
- duty cycle: percentage of the period the led is on, from 0 to 100
Setting a led in DIM0 or DIM1 mode makes it blink according to the pattern.
See the datasheet for details.
LP3944 can be found on Motorola A910 smartphone, where it drives the rgb
leds, the camera flash light and the lcds power.
Notes
-----
The chip is used mainly in embedded contexts, so this driver expects it is
registered using the i2c_board_info mechanism.
To register the chip at address 0x60 on adapter 0, set the platform data
according to include/linux/leds-lp3944.h, set the i2c board info:
static struct i2c_board_info __initdata a910_i2c_board_info[] = {
{
I2C_BOARD_INFO("lp3944", 0x60),
.platform_data = &a910_lp3944_leds,
},
};
and register it in the platform init function
i2c_register_board_info(0, a910_i2c_board_info,
ARRAY_SIZE(a910_i2c_board_info));

4xx/Axon EMAC ethernet nodes
The EMAC ethernet controller in IBM and AMCC 4xx chips, and also
the Axon bridge. To operate this needs to interact with a ths
special McMAL DMA controller, and sometimes an RGMII or ZMII
interface. In addition to the nodes and properties described
below, the node for the OPB bus on which the EMAC sits must have a
correct clock-frequency property.
i) The EMAC node itself
Required properties:
- device_type : "network"
- compatible : compatible list, contains 2 entries, first is
"ibm,emac-CHIP" where CHIP is the host ASIC (440gx,
405gp, Axon) and second is either "ibm,emac" or
"ibm,emac4". For Axon, thus, we have: "ibm,emac-axon",
"ibm,emac4"
- interrupts : <interrupt mapping for EMAC IRQ and WOL IRQ>
- interrupt-parent : optional, if needed for interrupt mapping
- reg : <registers mapping>
- local-mac-address : 6 bytes, MAC address
- mal-device : phandle of the associated McMAL node
- mal-tx-channel : 1 cell, index of the tx channel on McMAL associated
with this EMAC
- mal-rx-channel : 1 cell, index of the rx channel on McMAL associated
with this EMAC
- cell-index : 1 cell, hardware index of the EMAC cell on a given
ASIC (typically 0x0 and 0x1 for EMAC0 and EMAC1 on
each Axon chip)
- max-frame-size : 1 cell, maximum frame size supported in bytes
- rx-fifo-size : 1 cell, Rx fifo size in bytes for 10 and 100 Mb/sec
operations.
For Axon, 2048
- tx-fifo-size : 1 cell, Tx fifo size in bytes for 10 and 100 Mb/sec
operations.
For Axon, 2048.
- fifo-entry-size : 1 cell, size of a fifo entry (used to calculate
thresholds).
For Axon, 0x00000010
- mal-burst-size : 1 cell, MAL burst size (used to calculate thresholds)
in bytes.
For Axon, 0x00000100 (I think ...)
- phy-mode : string, mode of operations of the PHY interface.
Supported values are: "mii", "rmii", "smii", "rgmii",
"tbi", "gmii", rtbi", "sgmii".
For Axon on CAB, it is "rgmii"
- mdio-device : 1 cell, required iff using shared MDIO registers
(440EP). phandle of the EMAC to use to drive the
MDIO lines for the PHY used by this EMAC.
- zmii-device : 1 cell, required iff connected to a ZMII. phandle of
the ZMII device node
- zmii-channel : 1 cell, required iff connected to a ZMII. Which ZMII
channel or 0xffffffff if ZMII is only used for MDIO.
- rgmii-device : 1 cell, required iff connected to an RGMII. phandle
of the RGMII device node.
For Axon: phandle of plb5/plb4/opb/rgmii
- rgmii-channel : 1 cell, required iff connected to an RGMII. Which
RGMII channel is used by this EMAC.
Fox Axon: present, whatever value is appropriate for each
EMAC, that is the content of the current (bogus) "phy-port"
property.
Optional properties:
- phy-address : 1 cell, optional, MDIO address of the PHY. If absent,
a search is performed.
- phy-map : 1 cell, optional, bitmap of addresses to probe the PHY
for, used if phy-address is absent. bit 0x00000001 is
MDIO address 0.
For Axon it can be absent, though my current driver
doesn't handle phy-address yet so for now, keep
0x00ffffff in it.
- rx-fifo-size-gige : 1 cell, Rx fifo size in bytes for 1000 Mb/sec
operations (if absent the value is the same as
rx-fifo-size). For Axon, either absent or 2048.
- tx-fifo-size-gige : 1 cell, Tx fifo size in bytes for 1000 Mb/sec
operations (if absent the value is the same as
tx-fifo-size). For Axon, either absent or 2048.
- tah-device : 1 cell, optional. If connected to a TAH engine for
offload, phandle of the TAH device node.

zmii-channel = <0>;
};
ii) McMAL node

- device_type : "dma-controller"
- compatible : compatible list, containing 2 entries, first is
"ibm,mcmal-CHIP" where CHIP is the host ASIC (like
emac) and the second is either "ibm,mcmal" or

For Axon, "ibm,mcmal-axon","ibm,mcmal2"
- interrupts : <interrupt mapping for the MAL interrupts sources:
5 sources: tx_eob, rx_eob, serr, txde, rxde>.
For Axon: This is _different_ from the current
firmware. We use the "delayed" interrupts for txeob
and rxeob. Thus we end up with mapping those 5 MPIC
interrupts, all level positive sensitive: 10, 11, 32,
33, 34 (in decimal)
- dcr-reg : < DCR registers range >
- dcr-parent : if needed for dcr-reg

- compatible : compatible list, containing 2 entries, first is
"ibm,rgmii-CHIP" where CHIP is the host ASIC (like
EMAC) and the second is "ibm,rgmii".
For Axon, "ibm,rgmii-axon","ibm,rgmii"

Specifying GPIO information for devices
============================================
1) gpios property
-----------------
Nodes that makes use of GPIOs should define them using `gpios' property,
format of which is: <&gpio-controller1-phandle gpio1-specifier
&gpio-controller2-phandle gpio2-specifier
0 /* holes are permitted, means no GPIO 3 */
&gpio-controller4-phandle gpio4-specifier
...>;
Note that gpio-specifier length is controller dependent.
gpio-specifier may encode: bank, pin position inside the bank,
whether pin is open-drain and whether pin is logically inverted.
Example of the node using GPIOs:
node {
gpios = <&qe_pio_e 18 0>;
};
In this example gpio-specifier is "18 0" and encodes GPIO pin number,
and empty GPIO flags as accepted by the "qe_pio_e" gpio-controller.
2) gpio-controller nodes
------------------------
Every GPIO controller node must have #gpio-cells property defined,
this information will be used to translate gpio-specifiers.
Example of two SOC GPIO banks defined as gpio-controller nodes:
qe_pio_a: gpio-controller@1400 {
#gpio-cells = <2>;

Marvell Discovery mv64[345]6x System Controller chips
===========================================================
The Marvell mv64[345]60 series of system controller chips contain
many of the peripherals needed to implement a complete computer
system. In this section, we define device tree nodes to describe
the system controller chip itself and each of the peripherals
which it contains. Compatible string values for each node are
prefixed with the string "marvell,", for Marvell Technology Group Ltd.
1) The /system-controller node
This node is used to represent the system-controller and must be
present when the system uses a system controller chip. The top-level
system-controller node contains information that is global to all
devices within the system controller chip. The node name begins
with "system-controller" followed by the unit address, which is
the base address of the memory-mapped register set for the system
controller chip.
Required properties:
- ranges : Describes the translation of system controller addresses
for memory mapped registers.
- clock-frequency: Contains the main clock frequency for the system
controller chip.
- reg : This property defines the address and size of the
memory-mapped registers contained within the system controller
chip. The address specified in the "reg" property should match
the unit address of the system-controller node.
- #address-cells : Address representation for system controller
devices. This field represents the number of cells needed to
represent the address of the memory-mapped registers of devices
within the system controller chip.
- #size-cells : Size representation for for the memory-mapped
registers within the system controller chip.
- #interrupt-cells : Defines the width of cells used to represent
interrupts.
Optional properties:
- model : The specific model of the system controller chip. Such
as, "mv64360", "mv64460", or "mv64560".
- compatible : A string identifying the compatibility identifiers
of the system controller chip.
The system-controller node contains child nodes for each system
controller device that the platform uses. Nodes should not be created
for devices which exist on the system controller chip but are not used
Example Marvell Discovery mv64360 system-controller node:
system-controller@f1000000 { /* Marvell Discovery mv64360 */
#address-cells = <1>;
#size-cells = <1>;
model = "mv64360"; /* Default */
compatible = "marvell,mv64360";
clock-frequency = <133333333>;
reg = <0xf1000000 0x10000>;
virtual-reg = <0xf1000000>;
ranges = <0x88000000 0x88000000 0x1000000 /* PCI 0 I/O Space */

0xf2000000 0xf2000000 0x0040000>;/* Integrated SRAM */
[ child node definitions... ]
}
2) Child nodes of /system-controller
a) Marvell Discovery MDIO bus
The MDIO is a bus to which the PHY devices are connected. For each
device that exists on this bus, a child node should be created. See
the definition of the PHY node below for an example of how to define
a PHY.
Required properties:
- #address-cells : Should be <1>
- #size-cells : Should be <0>
- device_type : Should be "mdio"
- compatible : Should be "marvell,mv64360-mdio"
Example:
mdio {
#address-cells = <1>;
#size-cells = <0>;
device_type = "mdio";
compatible = "marvell,mv64360-mdio";
ethernet-phy@0 {
......
};
};
b) Marvell Discovery ethernet controller
The Discover ethernet controller is described with two levels
of nodes. The first level describes an ethernet silicon block
and the second level describes up to 3 ethernet nodes within
that block. The reason for the multiple levels is that the
registers for the node are interleaved within a single set
of registers. The "ethernet-block" level describes the
shared register set, and the "ethernet" nodes describe ethernet
port-specific properties.
Ethernet block node
Required properties:
- #address-cells : <1>
- #size-cells : <0>
- compatible : "marvell,mv64360-eth-block"
- reg : Offset and length of the register set for this block
Example Discovery Ethernet block node:
ethernet-block@2000 {
#address-cells = <1>;
#size-cells = <0>;
compatible = "marvell,mv64360-eth-block";
reg = <0x2000 0x2000>;
ethernet@0 {
.......
};
};
Ethernet port node
Required properties:
- device_type : Should be "network".
- compatible : Should be "marvell,mv64360-eth".
- reg : Should be <0>, <1>, or <2>, according to which registers
within the silicon block the device uses.
- interrupts : <a> where a is the interrupt number for the port.
- interrupt-parent : the phandle for the interrupt controller
that services interrupts for this device.
- phy : the phandle for the PHY connected to this ethernet
controller.
- local-mac-address : 6 bytes, MAC address
Example Discovery Ethernet port node:
ethernet@0 {
device_type = "network";
compatible = "marvell,mv64360-eth";
reg = <0>;
interrupts = <32>;
interrupt-parent = <&PIC>;
phy = <&PHY0>;
local-mac-address = [ 00 00 00 00 00 00 ];
};
c) Marvell Discovery PHY nodes
Required properties:
- device_type : Should be "ethernet-phy"
- interrupts : <a> where a is the interrupt number for this phy.
- interrupt-parent : the phandle for the interrupt controller that
services interrupts for this device.
- reg : The ID number for the phy, usually a small integer
Example Discovery PHY node:
ethernet-phy@1 {
device_type = "ethernet-phy";
compatible = "broadcom,bcm5421";
interrupts = <76>; /* GPP 12 */
interrupt-parent = <&PIC>;
reg = <1>;
};
d) Marvell Discovery SDMA nodes
Represent DMA hardware associated with the MPSC (multiprotocol
serial controllers).
Required properties:
- compatible : "marvell,mv64360-sdma"
- reg : Offset and length of the register set for this device
- interrupts : <a> where a is the interrupt number for the DMA
device.
- interrupt-parent : the phandle for the interrupt controller
that services interrupts for this device.

SPI (Serial Peripheral Interface) busses
SPI busses can be described with a node for the SPI master device
and a set of child nodes for each SPI slave on the bus. For this
discussion, it is assumed that the system's SPI controller is in
SPI master mode. This binding does not describe SPI controllers
in slave mode.
The SPI master node requires the following properties:
- #address-cells - number of cells required to define a chip select
address on the SPI bus.
- #size-cells - should be zero.
- compatible - name of SPI bus controller following generic names
recommended practice.
No other properties are required in the SPI bus node. It is assumed
that a driver for an SPI bus device will understand that it is an SPI bus.
However, the binding does not attempt to define the specific method for
assigning chip select numbers. Since SPI chip select configuration is
flexible and non-standardized, it is left out of this binding with the
assumption that board specific platform code will be used to manage
chip selects. Individual drivers can define additional properties to
support describing the chip select layout.
SPI slave nodes must be children of the SPI master node and can
contain the following properties.
- reg - (required) chip select address of device.
- compatible - (required) name of SPI device following generic names
recommended practice
- spi-max-frequency - (required) Maximum SPI clocking speed of device in Hz
- spi-cpol - (optional) Empty property indicating device requires
inverse clock polarity (CPOL) mode
- spi-cpha - (optional) Empty property indicating device requires
shifted clock phase (CPHA) mode
- spi-cs-high - (optional) Empty property indicating device requires
chip select active high
SPI example for an MPC5200 SPI bus:
spi@f00 {
#address-cells = <1>;
#size-cells = <0>;

USB EHCI controllers
Required properties:
- compatible : should be "usb-ehci".
- reg : should contain at least address and length of the standard EHCI
register set for the device. Optional platform-dependent registers
(debug-port or other) can be also specified here, but only after
definition of standard EHCI registers.
- interrupts : one EHCI interrupt should be described here.
If device registers are implemented in big endian mode, the device
node should have "big-endian-regs" property.
If controller implementation operates with big endian descriptors,
"big-endian-desc" property should be specified.
If both big endian registers and descriptors are used by the controller
implementation, "big-endian" property can be specified instead of having
both "big-endian-regs" and "big-endian-desc".

d) Xilinx IP cores
The Xilinx EDK toolchain ships with a set of IP cores (devices) for use
in Xilinx Spartan and Virtex FPGAs. The devices cover the whole range
of standard device types (network, serial, etc.) and miscellaneous
devices (gpio, LCD, spi, etc). Also, since these devices are
implemented within the fpga fabric every instance of the device can be
synthesised with different options that change the behaviour.
Each IP-core has a set of parameters which the FPGA designer can use to
control how the core is synthesized. Historically, the EDK tool would
extract the device parameters relevant to device drivers and copy them
into an 'xparameters.h' in the form of #define symbols. This tells the
device drivers how the IP cores are configured, but it requres the kernel
to be recompiled every time the FPGA bitstream is resynthesized.
The new approach is to export the parameters into the device tree and
generate a new device tree each time the FPGA bitstream changes. The
parameters which used to be exported as #defines will now become
properties of the device node. In general, device nodes for IP-cores
will take the following form:
(name): (generic-name)@(base-address) {
compatible = "xlnx,(ip-core-name)-(HW_VER)"
[, (list of compatible devices), ...];
reg = <(baseaddr) (size)>;
interrupt-parent = <&interrupt-controller-phandle>;
interrupts = < ... >;
xlnx,(parameter1) = "(string-value)";
xlnx,(parameter2) = <(int-value)>;
};
(generic-name): an open firmware-style name that describes the
generic class of device. Preferably, this is one word, such
as 'serial' or 'ethernet'.
(ip-core-name): the name of the ip block (given after the BEGIN
directive in system.mhs). Should be in lowercase
and all underscores '_' converted to dashes '-'.
(name): is derived from the "PARAMETER INSTANCE" value.
(parameter#): C_* parameters from system.mhs. The C_ prefix is
dropped from the parameter name, the name is converted
to lowercase and all underscore '_' characters are
converted to dashes '-'.
(baseaddr): the baseaddr parameter value (often named C_BASEADDR).
(HW_VER): from the HW_VER parameter.
(size): the address range size (often C_HIGHADDR - C_BASEADDR + 1).
Typically, the compatible list will include the exact IP core version
followed by an older IP core version which implements the same
interface or any other device with the same interface.
'reg', 'interrupt-parent' and 'interrupts' are all optional properties.
For example, the following block from system.mhs:
BEGIN opb_uartlite
PARAMETER INSTANCE = opb_uartlite_0
PARAMETER HW_VER = 1.00.b
PARAMETER C_BAUDRATE = 115200
PARAMETER C_DATA_BITS = 8
PARAMETER C_ODD_PARITY = 0
PARAMETER C_USE_PARITY = 0
PARAMETER C_CLK_FREQ = 50000000
PARAMETER C_BASEADDR = 0xEC100000
PARAMETER C_HIGHADDR = 0xEC10FFFF
BUS_INTERFACE SOPB = opb_7
PORT OPB_Clk = CLK_50MHz
PORT Interrupt = opb_uartlite_0_Interrupt
PORT RX = opb_uartlite_0_RX
PORT TX = opb_uartlite_0_TX
PORT OPB_Rst = sys_bus_reset_0
END
becomes the following device tree node:
opb_uartlite_0: serial@ec100000 {
device_type = "serial";
compatible = "xlnx,opb-uartlite-1.00.b";
reg = <ec100000 10000>;
interrupt-parent = <&opb_intc_0>;
interrupts = <1 0>; // got this from the opb_intc parameters
current-speed = <d#115200>; // standard serial device prop
clock-frequency = <d#50000000>; // standard serial device prop
xlnx,data-bits = <8>;
xlnx,odd-parity = <0>;
xlnx,use-parity = <0>;
};
Some IP cores actually implement 2 or more logical devices. In
this case, the device should still describe the whole IP core with
a single node and add a child node for each logical device. The
ranges property can be used to translate from parent IP-core to the
registers of each device. In addition, the parent node should be
compatible with the bus type 'xlnx,compound', and should contain
#address-cells and #size-cells, as with any other bus. (Note: this
makes the assumption that both logical devices have the same bus
binding. If this is not true, then separate nodes should be used
for each logical device). The 'cell-index' property can be used to
enumerate logical devices within an IP core. For example, the
following is the system.mhs entry for the dual ps2 controller found
on the ml403 reference design.
BEGIN opb_ps2_dual_ref
PARAMETER INSTANCE = opb_ps2_dual_ref_0
PARAMETER HW_VER = 1.00.a
PARAMETER C_BASEADDR = 0xA9000000
PARAMETER C_HIGHADDR = 0xA9001FFF
BUS_INTERFACE SOPB = opb_v20_0
PORT Sys_Intr1 = ps2_1_intr
PORT Sys_Intr2 = ps2_2_intr
PORT Clkin1 = ps2_clk_rx_1
PORT Clkin2 = ps2_clk_rx_2
PORT Clkpd1 = ps2_clk_tx_1
PORT Clkpd2 = ps2_clk_tx_2
PORT Rx1 = ps2_d_rx_1
PORT Rx2 = ps2_d_rx_2
PORT Txpd1 = ps2_d_tx_1
PORT Txpd2 = ps2_d_tx_2
END
It would result in the following device tree nodes:
opb_ps2_dual_ref_0: opb-ps2-dual-ref@a9000000 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "xlnx,compound";
ranges = <0 a9000000 2000>;
// If this device had extra parameters, then they would
// go here.
ps2@0 {
compatible = "xlnx,opb-ps2-dual-ref-1.00.a";
reg = <0 40>;
interrupt-parent = <&opb_intc_0>;
interrupts = <3 0>;
cell-index = <0>;
};

compatible = "xlnx,opb-ps2-dual-ref-1.00.a";
reg = <1000 40>;
interrupt-parent = <&opb_intc_0>;
interrupts = <3 0>;
cell-index = <0>;
};
};
Also, the system.mhs file defines bus attachments from the processor
to the devices. The device tree structure should reflect the bus
attachments. Again an example; this system.mhs fragment:
BEGIN ppc405_virtex4
PARAMETER INSTANCE = ppc405_0

Gives this device tree (some properties removed for clarity):

};
opb_intc_0: interrupt-controller@d1000fc0 {

};
};
That covers the general approach to binding xilinx IP cores into the
device tree. The following are bindings for specific devices:
i) Xilinx ML300 Framebuffer
Simple framebuffer device from the ML300 reference design (also on the
ML403 reference design as well as others).
Optional properties:
- resolution = <xres yres> : pixel resolution of framebuffer. Some
implementations use a different resolution.
Default is <d#640 d#480>
- virt-resolution = <xvirt yvirt> : Size of framebuffer in memory.
Default is <d#1024 d#480>.
- rotate-display (empty) : rotate display 180 degrees.
ii) Xilinx SystemACE
The Xilinx SystemACE device is used to program FPGAs from an FPGA
bitstream stored on a CF card. It can also be used as a generic CF
interface device.
Optional properties:
- 8-bit (empty) : Set this property for SystemACE in 8 bit mode
iii) Xilinx EMAC and Xilinx TEMAC
Xilinx Ethernet devices. In addition to general xilinx properties
listed above, nodes for these devices should include a phy-handle
property, and may include other common network device properties
like local-mac-address.

Xilinx uartlite devices are simple fixed speed serial ports.
Required properties:
- current-speed : Baud rate of uartlite
v) Xilinx hwicap
Xilinx hwicap devices provide access to the configuration logic
of the FPGA through the Internal Configuration Access Port
(ICAP). The ICAP enables partial reconfiguration of the FPGA,
readback of the configuration information, and some control over
'warm boots' of the FPGA fabric.
Required properties:
- xlnx,family : The family of the FPGA, necessary since the
capabilities of the underlying ICAP hardware
differ between different families. May be
'virtex2p', 'virtex4', or 'virtex5'.
vi) Xilinx Uart 16550
Xilinx UART 16550 devices are very similar to the NS16550 but with
different register spacing and an offset from the base address.
Required properties:
- clock-frequency : Frequency of the clock input
- reg-offset : A value of 3 is required
- reg-shift : A value of 2 is required

@ -390,6 +390,30 @@ later date. It differs between i2c drivers and as such can be confusing.
To see which chip variants are supported you can look in the i2c driver code
for the i2c_device_id table. This lists all the possibilities.
There are two more helper functions:
v4l2_i2c_new_subdev_cfg: this function adds new irq and platform_data
arguments and has both 'addr' and 'probed_addrs' arguments: if addr is not
0 then that will be used (non-probing variant), otherwise the probed_addrs
are probed.
For example: this will probe for address 0x10:
struct v4l2_subdev *sd = v4l2_i2c_new_subdev_cfg(v4l2_dev, adapter,
"module_foo", "chipid", 0, NULL, 0, I2C_ADDRS(0x10));
v4l2_i2c_new_subdev_board uses an i2c_board_info struct which is passed
to the i2c driver and replaces the irq, platform_data and addr arguments.
If the subdev supports the s_config core ops, then that op is called with
the irq and platform_data arguments after the subdev was setup. The older
v4l2_i2c_new_(probed_)subdev functions will call s_config as well, but with
irq set to 0 and platform_data set to NULL.
Note that in the next kernel release the functions v4l2_i2c_new_subdev,
v4l2_i2c_new_probed_subdev and v4l2_i2c_new_probed_subdev_addr will all be
replaced by a single v4l2_i2c_new_subdev that is identical to
v4l2_i2c_new_subdev_cfg but without the irq and platform_data arguments.

The hpwdt driver also has three (3) module parameters. They are the following:
The hpwdt driver also has four (4) module parameters. They are the following:
soft_margin - allows the user to set the watchdog timer value
allow_kdump - allows the user to save off a kernel dump image after an NMI
nowayout - basic watchdog parameter that does not allow the timer to
be restarted or an impending ASR to be escaped.
priority - determines whether or not the hpwdt driver is first on the
die_notify list to handle NMIs or last. The default value
for this module parameter is 0 or LAST. If the user wants to
enable NMI sourcing then reload the hpwdt driver with
priority=1 (and boot with nmi_watchdog=0).
NOTE: More information about watchdog drivers in general, including the ioctl
interface to /dev/watchdog can be found in
Documentation/watchdog/watchdog-api.txt and Documentation/IPMI.txt.
The NMI sourcing capability is disabled when the driver discovers that the
nmi_watchdog is turned on (nmi_watchdog = 1). This is due to the inability to
The priority parameter was introduced due to other kernel software that relied
on handling NMIs (like oprofile). Keeping hpwdt's priority at 0 (or LAST)
enables the users of NMIs for non critical events to be work as expected.
The NMI sourcing capability is disabled by default due to the inability to
distinguish between "NMI Watchdog Ticks" and "HW generated NMI events" in the
Linux kernel. What this means is that the hpwdt nmi handler code is called
each time the NMI signal fires off. This could amount to several thousands of
NMIs in a matter of seconds. If a user sees the Linux kernel's "dazed and
confused" message in the logs or if the system gets into a hung state, then
the user should reboot with nmi_watchdog=0.
the hpwdt driver can be reloaded with the "priority" module parameter set
(priority=1).
1. If the kernel has not been booted with nmi_watchdog turned off then
edit /boot/grub/menu.lst and place the nmi_watchdog=0 at the end of the
currently booting kernel line.
2. reboot the sever
3. Once the system comes up perform a rmmod hpwdt
4. insmod /lib/modules/`uname -r`/kernel/drivers/char/watchdog/hpwdt.ko priority=1
Now, the hpwdt can successfully receive and source the NMI and provide a log
message that details the reason for the NMI (as determined by the HP BIOS).

Write Back Policy:
Cached data will be written back to SDRAM only when needed.
This can give a nice increase in performance, but beware of
broken drivers that do not properly invalidate/flush their
cache.
Write Through Policy:
Cached data will always be written back to SDRAM when the
cache is updated. This is a completely safe setting, but
performance is worse than Write Back.
If you are unsure of the options and you want to be safe,
