Device Tree Dynamic Object format internals
-------------------------------------------
The Device Tree for most platforms is a static representation of
the hardware capabilities. This is insufficient for platforms
that need to dynamically insert Device Tree fragments into the
live tree.
This document explains the the Device Tree object format and
modifications made to the Device Tree compiler, which make it possible.
1. Simplified Problem Definition
--------------------------------
Assume we have a platform which boots using following simplified Device Tree.
---- foo.dts -----------------------------------------------------------------
/* FOO platform */
/ {
compatible = "corp,foo";
/* shared resources */
res: res {
};
/* On chip peripherals */
ocp: ocp {
/* peripherals that are always instantiated */
peripheral1 { ... };
};
};
---- foo.dts -----------------------------------------------------------------
We have a number of peripherals that after probing (using some undefined method)
should result in different Device Tree configuration.
We cannot boot with this static tree because due to the configuration of the
foo platform there exist multiple conficting peripherals DT fragments.
So for the bar peripheral we would have this:
---- foo+bar.dts -------------------------------------------------------------
/* FOO platform + bar peripheral */
/ {
compatible = "corp,foo";
/* shared resources */
res: res {
};
/* On chip peripherals */
ocp: ocp {
/* peripherals that are always instantiated */
peripheral1 { ... };
/* bar peripheral */
bar {
compatible = "corp,bar";
... /* various properties and child nodes */
};
};
};
---- foo+bar.dts -------------------------------------------------------------
While for the baz peripheral we would have this:
---- foo+baz.dts -------------------------------------------------------------
/* FOO platform + baz peripheral */
/ {
compatible = "corp,foo";
/* shared resources */
res: res {
/* baz resources */
baz_res: res_baz { ... };
};
/* On chip peripherals */
ocp: ocp {
/* peripherals that are always instantiated */
peripheral1 { ... };
/* baz peripheral */
baz {
compatible = "corp,baz";
/* reference to another point in the tree */
ref-to-res = <&baz_res>;
... /* various properties and child nodes */
};
};
};
---- foo+baz.dts -------------------------------------------------------------
We note that the baz case is more complicated, since the baz peripheral needs to
reference another node in the DT tree.
2. Device Tree Object Format Requirements
-----------------------------------------
Since the Device Tree is used for booting a number of very different hardware
platforms it is imperative that we tread very carefully.
2.a) No changes to the Device Tree binary format for the base tree. We cannot
modify the tree format at all and all the information we require should be
encoded using Device Tree itself. We can add nodes that can be safely ignored
by both bootloaders and the kernel. The plugin dtbs are optionally tagged
with a different magic number in the header but otherwise they're simple
blobs.
2.b) Changes to the DTS source format should be absolutely minimal, and should
only be needed for the DT fragment definitions, and not the base boot DT.
2.c) An explicit option should be used to instruct DTC to generate the required
information needed for object resolution. Platforms that don't use the
dynamic object format can safely ignore it.
2.d) Finally, DT syntax changes should be kept to a minimum. It should be
possible to express everything using the existing DT syntax.
3. Implementation
-----------------
The basic unit of addressing in Device Tree is the phandle. Turns out it's
relatively simple to extend the way phandles are generated and referenced
so that it's possible to dynamically convert symbolic references (labels)
to phandle values. This is a valid assumption as long as the author uses
reference syntax and does not assign phandle values manually (which might
be a problem with decompiled source files).
We can roughly divide the operation into two steps.
3.a) Compilation of the base board DTS file using the '-@' option
generates a valid DT blob with an added __symbols__ node at the root node,
containing a list of all nodes that are marked with a label.
Using the foo.dts file above the following node will be generated;
$ dtc -@ -O dtb -o foo.dtb -b 0 foo.dts
$ fdtdump foo.dtb
...
/ {
...
res {
...
phandle = <0x00000001>;
...
};
ocp {
...
phandle = <0x00000002>;
...
};
__symbols__ {
res="/res";
ocp="/ocp";
};
};
Notice that all the nodes that had a label have been recorded, and that
phandles have been generated for them.
This blob can be used to boot the board normally, the __symbols__ node will
be safely ignored both by the bootloader and the kernel (the only loss will
be a few bytes of memory and disk space).
We generate a __symbols__ node to record nodes that had labels in the base
tree (or subsequent loaded overlays) so that they can be matched up with
references made to them in Device Tree objects.
3.b) The Device Tree fragments must be compiled with the same option but they
must also have a tag (/plugin/) that allows undefined references to nodes
that are not present at compilation time to be recorded so that the runtime
loader can fix them.
So the bar peripheral's DTS format would be of the form:
/dts-v1/;
/plugin/; /* allow undefined references and record them */
/ {
.... /* various properties for loader use; i.e. part id etc. */
fragment@0 {
target = <&ocp>;
__overlay__ {
/* bar peripheral */
bar {
compatible = "corp,bar";
... /* various properties and child nodes */
}
};
};
};
Note that there's a target property that specifies the location where the
contents of the overlay node will be placed, and it references the node
in the foo.dts file.
$ dtc -@ -O dtb -o bar.dtbo -b 0 bar.dts
$ fdtdump bar.dtbo
...
/ {
... /* properties */
fragment@0 {
target = <0xffffffff>;
__overlay__ {
bar {
compatible = "corp,bar";
... /* various properties and child nodes */
}
};
};
__fixups__ {
ocp = "/fragment@0:target:0";
};
};
No __symbols__ node has been generated (no label in bar.dts).
Note that the target's ocp label is undefined, so the phandle
value is filled with the illegal value '0xffffffff', while a __fixups__
node has been generated, which marks the location in the tree where
the label lookup should store the runtime phandle value of the ocp node.
The format of the __fixups__ node entry is
<label> = "<local-full-path>:<property-name>:<offset>"
[, "<local-full-path>:<property-name>:<offset>"...];
<label> Is the label we're referring
<local-full-path> Is the full path of the node the reference is
<property-name> Is the name of the property containing the
reference
<offset> The offset (in bytes) of where the property's
phandle value is located.
Doing the same with the baz peripheral's DTS format is a little bit more
involved, since baz contains references to local labels which require
local fixups.
/dts-v1/;
/plugin/; /* allow undefined label references and record them */
/ {
.... /* various properties for loader use; i.e. part id etc. */
fragment@0 {
target = <&res>;
__overlay__ {
/* baz resources */
baz_res: res_baz { ... };
};
};
fragment@1 {
target = <&ocp>;
__overlay__ {
/* baz peripheral */
baz {
compatible = "corp,baz";
/* reference to another point in the tree */
ref-to-res = <&baz_res>;
... /* various properties and child nodes */
}
};
};
};
Note that &bar_res reference.
$ dtc -@ -O dtb -o baz.dtbo -b 0 baz.dts
$ fdtdump baz.dtbo
...
/ {
... /* properties */
fragment@0 {
target = <0xffffffff>;
__overlay__ {
res_baz {
....
phandle = <0x00000001>;
};
};
};
fragment@1 {
target = <0xffffffff>;
__overlay__ {
baz {
compatible = "corp,baz";
... /* various properties and child nodes */
ref-to-res = <0x00000001>;
}
};
};
__fixups__ {
res = "/fragment@0:target:0";
ocp = "/fragment@1:target:0";
};
__local_fixups__ {
fragment@1 {
__overlay__ {
baz {
ref-to-res = <0>;
};
};
};
};
};
This is similar to the bar case, but the reference of a local label by the
baz node generates a __local_fixups__ entry that records the place that the
local reference is being made. No matter how phandles are allocated from dtc
the run time loader must apply an offset to each phandle in every dynamic
DT object loaded. The __local_fixups__ node records the offset relative to the
start of every local reference within that property so that the loader can apply
the offset.

\begin{abstract}
We present a method for booting a \ppc{}\R Linux\R kernel on an
embedded machine. To do this, we supply the kernel with a compact
flattened-tree representation of the system's hardware based on the
device tree supplied by Open Firmware on IBM\R servers and Apple\R
Power Macintosh\R machines.
The ``blob'' representing the device tree can be created using \dtc
--- the Device Tree Compiler --- that turns a simple text
representation of the tree into the compact representation used by
the kernel. The compiler can produce either a binary ``blob'' or an
assembler file ready to be built into a firmware or bootwrapper
image.
This flattened-tree approach is now the only supported method of
booting a \texttt{ppc64} kernel without Open Firmware, and we plan
to make it the only supported method for all \texttt{powerpc}
kernels in the future.
\end{abstract}
\section{Introduction}
\subsection{OF and the device tree}
Historically, ``everyday'' \ppc machines have booted with the help of
\of (OF), a firmware environment defined by IEEE1275 \cite{IEEE1275}.
Among other boot-time services, OF maintains a device tree that
describes all of the system's hardware devices and how they're
connected. During boot, before taking control of memory management,
the Linux kernel uses OF calls to scan the device tree and transfer it
to an internal representation that is used at run time to look up
various device information.
The device tree consists of nodes representing devices or
buses\footnote{Well, mostly. There are a few special exceptions.}.
Each node contains \emph{properties}, name--value pairs that give
information about the device. The values are arbitrary byte strings,
and for some properties, they contain tables or other structured
information.
\subsection{The bad old days}
Embedded systems, by contrast, usually have a minimal firmware that
might supply a few vital system parameters (size of RAM and the like),
but nothing as detailed or complete as the OF device tree. This has
meant that the various 32-bit \ppc embedded ports have required a
variety of hacks spread across the kernel to deal with the lack of
device tree. These vary from specialised boot wrappers to parse
parameters (which are at least reasonably localised) to
CONFIG-dependent hacks in drivers to override normal probe logic with
hardcoded addresses for a particular board. As well as being ugly of
itself, such CONFIG-dependent hacks make it hard to build a single
kernel image that supports multiple embedded machines.
Until relatively recently, the only 64-bit \ppc machines without OF
were legacy (pre-POWER5\R) iSeries\R machines. iSeries machines often
only have virtual IO devices, which makes it quite simple to work
around the lack of a device tree. Even so, the lack means the iSeries
boot sequence must be quite different from the pSeries or Macintosh,
which is not ideal.
The device tree also presents a problem for implementing \kexec. When
the kernel boots, it takes over full control of the system from OF,
even re-using OF's memory. So, when \kexec comes to boot another
kernel, OF is no longer around for the second kernel to query.
\section{The Flattened Tree}
In May 2005 \benh implemented a new approach to handling the device
tree that addresses all these problems. When booting on OF systems,
the first thing the kernel runs is a small piece of code in
\texttt{prom\_init.c}, which executes in the context of OF. This code
walks the device tree using OF calls, and transcribes it into a
compact, flattened format. The resulting device tree ``blob'' is then
passed to the kernel proper, which eventually unflattens the tree into
its runtime form. This blob is the only data communicated between the
\texttt{prom\_init.c} bootstrap and the rest of the kernel.
When OF isn't available, either because the machine doesn't have it at
all or because \kexec has been used, the kernel instead starts
directly from the entry point taking a flattened device tree. The
device tree blob must be passed in from outside, rather than generated
by part of the kernel from OF. For \kexec, the userland
\texttt{kexec} tools build the blob from the runtime device tree
before invoking the new kernel. For embedded systems the blob can
come either from the embedded bootloader, or from a specialised
version of the \texttt{zImage} wrapper for the system in question.
\subsection{Properties of the flattened tree}
The flattened tree format should be easy to handle, both for the
kernel that parses it and the bootloader that generates it. In
particular, the following properties are desirable:
\begin{itemize}
\item \emph{relocatable}: the bootloader or kernel should be able to
move the blob around as a whole, without needing to parse or adjust
its internals. In practice that means we must not use pointers
within the blob.
\item \emph{insert and delete}: sometimes the bootloader might want to
make tweaks to the flattened tree, such as deleting or inserting a
node (or whole subtree). It should be possible to do this without
having to effectively regenerate the whole flattened tree. In
practice this means limiting the use of internal offsets in the blob
that need recalculation if a section is inserted or removed with
\texttt{memmove()}.
\item \emph{compact}: embedded systems are frequently short of
resources, particularly RAM and flash memory space. Thus, the tree
representation should be kept as small as conveniently possible.
\end{itemize}

\caption{Device tree blob layout}
\label{fig:blob-layout}
\end{figure}
The format for the blob we devised, was first described on the
\texttt{linuxppc64-dev} mailing list in \cite{noof1}. The format has
since evolved through various revisions, and the current version is
included as part of the \dtc (see \S\ref{sec:dtc}) git tree,
\cite{dtcgit}.
Figure \ref{fig:blob-layout} shows the layout of the blob of data
containing the device tree. It has three sections of variable size:
the \emph{memory reserve table}, the \emph{structure block} and the
\emph{strings block}. A small header gives the blob's size and
version and the locations of the three sections, plus a handful of
vital parameters used during early boot.
The memory reserve map section gives a list of regions of memory that
the kernel must not use\footnote{Usually such ranges contain some data
structure initialised by the firmware that must be preserved by the
kernel.}. The list is represented as a simple array of (address,
size) pairs of 64 bit values, terminated by a zero size entry. The
strings block is similarly simple, consisting of a number of
null-terminated strings appended together, which are referenced from
the structure block as described below.
The structure block contains the device tree proper. Each node is
introduced with a 32-bit \dtbeginnode tag, followed by the node's name
as a null-terminated string, padded to a 32-bit boundary. Then
follows all of the properties of the node, each introduced with a
\dtprop tag, then all of the node's subnodes, each introduced with
their own \dtbeginnode tag. The node ends with an \dtendnode tag, and
after the \dtendnode for the root node is an \dtend tag, indicating
the end of the whole tree\footnote{This is redundant, but included for
ease of parsing.}. The structure block starts with the \dtbeginnode
introducing the description of the root node (named \texttt{/}).
Each property, after the \dtprop, has a 32-bit value giving an offset
from the beginning of the strings block at which the property name is
stored. Because it's common for many nodes to have properties with
the same name, this approach can substantially reduce the total size
of the blob. The name offset is followed by the length of the
property value (as a 32-bit value) and then the data itself padded to
a 32-bit boundary.
\subsection{Contents of the tree}
\label{sec:treecontents}
Having seen how to represent the device tree structure as a flattened
blob, what actually goes into the tree? The short answer is ``the
same as an OF tree''. On OF systems, the flattened tree is
transcribed directly from the OF device tree, so for simplicity we
also use OF conventions for the tree on other systems.
In many cases a flat tree can be simpler than a typical OF provided
device tree. The flattened tree need only provide those nodes and
properties that the kernel actually requires; the flattened tree
generally need not include devices that the kernel can probe itself.
For example, an OF device tree would normally include nodes for each
PCI device on the system. A flattened tree need only include nodes
for the PCI host bridges; the kernel will scan the buses thus
described to find the subsidiary devices. The device tree can include
nodes for devices where the kernel needs extra information, though:
for example, for ISA devices on a subsidiary PCI/ISA bridge, or for
devices with unusual interrupt routing.
Where they exist, we follow the IEEE1275 bindings that specify how to
describe various buses in the device tree (for example,
\cite{IEEE1275-pci} describe how to represent PCI devices). The
standard has not been updated for a long time, however, and lacks
bindings for many modern buses and devices. In particular, embedded
specific devices such as the various System-on-Chip buses are not
covered. We intend to create new bindings for such buses, in keeping
with the general conventions of IEEE1275 (a simple such binding for a
System-on-Chip bus was included in \cite{noof5} a revision of
\cite{noof1}).
One complication arises for representing ``phandles'' in the flattened
tree. In OF, each node in the tree has an associated phandle, a
32-bit integer that uniquely identifies the node\footnote{In practice
usually implemented as a pointer or offset within OF memory.}. This
handle is used by the various OF calls to query and traverse the tree.
Sometimes phandles are also used within the tree to refer to other
nodes in the tree. For example, devices that produce interrupts
generally have an \texttt{interrupt-parent} property giving the
phandle of the interrupt controller that handles interrupts from this
device. Parsing these and other interrupt related properties allows
the kernel to build a complete representation of the system's
interrupt tree, which can be quite different from the tree of bus
connections.
In the flattened tree, a node's phandle is represented by a special
\phandle property. When the kernel generates a flattened tree from
OF, it adds a \phandle property to each node, containing the phandle
retrieved from OF. When the tree is generated without OF, however,
only nodes that are actually referred to by phandle need to have this
property.
Another complication arises because nodes in an OF tree have two
names. First they have the ``unit name'', which is how the node is
referred to in an OF path. The unit name generally consists of a
device type followed by an \texttt{@} followed by a \emph{unit
address}. For example \texttt{/memory@0} is the full path of a memory
node at address 0, \texttt{/ht@0,f2000000/pci@1} is the path of a PCI
bus node, which is under a HyperTransport\tm bus node. The form of
the unit address is bus dependent, but is generally derived from the
node's \texttt{reg} property. In addition, nodes have a property,
\texttt{name}, whose value is usually equal to the first path of the
unit name. For example, the nodes in the previous example would have
\texttt{name} properties equal to \texttt{memory} and \texttt{pci},
respectively. To save space in the blob, the current version of the
flattened tree format only requires the unit names to be present.
When the kernel unflattens the tree, it automatically generates a
\texttt{name} property from the node's path name.

\caption{Example \dtc source}
\label{fig:dts}
\end{figure}
As we've seen, the flattened device tree format provides a convenient
way of communicating device tree information to the kernel. It's
simple for the kernel to parse, and simple for bootloaders to
manipulate. On OF systems, it's easy to generate the flattened tree
by walking the OF maintained tree. However, for embedded systems, the
flattened tree must be generated from scratch.
Embedded bootloaders are generally built for a particular board. So,
it's usually possible to build the device tree blob at compile time
and include it in the bootloader image. For minor revisions of the
board, the bootloader can contain code to make the necessary tweaks to
the tree before passing it to the booted kernel.
The device trees for embedded boards are usually quite simple, and
it's possible to hand construct the necessary blob by hand, but doing
so is tedious. The ``device tree compiler'', \dtc{}\footnote{\dtc can
be obtained from \cite{dtcgit}.}, is designed to make creating device
tree blobs easier by converting a text representation of the tree
into the necessary blob.
\subsection{Input and output formats}
As well as the normal mode of compiling a device tree blob from text
source, \dtc can convert a device tree between a number of
representations. It can take its input in one of three different
formats:
\begin{itemize}
\item source, the normal case. The device tree is described in a text
form, described in \S\ref{sec:dts}.
\item blob (\texttt{dtb}), the flattened tree format described in
\S\ref{sec:format}. This mode is useful for checking a pre-existing
device tree blob.
\item filesystem (\texttt{fs}), input is a directory tree in the
layout of \texttt{/proc/device-tree} (roughly, a directory for each
node in the device tree, a file for each property). This is useful
for building a blob for the device tree in use by the currently
running kernel.
\end{itemize}
In addition, \dtc can output the tree in one of three different
formats:
\begin{itemize}
\item blob (\texttt{dtb}), as in \S\ref{sec:format}. The most
straightforward use of \dtc is to compile from ``source'' to
``blob'' format.
\item source (\texttt{dts}), as in \S\ref{sec:dts}. If used with blob
input, this allows \dtc to act as a ``decompiler''.
\item assembler source (\texttt{asm}). \dtc can produce an assembler
file, which will assemble into a \texttt{.o} file containing the
device tree blob, with symbols giving the beginning of the blob and
its various subsections. This can then be linked directly into a
bootloader or firmware image.
\end{itemize}
For maximum applicability, \dtc can both read and write any of the
existing revisions of the blob format. When reading, \dtc takes the
version from the blob header, and when writing it takes a command line
option specifying the desired version. It automatically makes any
necessary adjustments to the tree that are necessary for the specified
version. For example, formats before 0x10 require each node to have
an explicit \texttt{name} property. When \dtc creates such a blob, it
will automatically generate \texttt{name} properties from the unit
names.
\subsection{Source format}
\label{sec:dts}
The ``source'' format for \dtc is a text description of the device
tree in a vaguely C-like form. Figure \ref{fig:dts} shows an
example. The file starts with \texttt{/memreserve/} directives, which
gives address ranges to add to the output blob's memory reserve table,
then the device tree proper is described.
Nodes of the tree are introduced with the node name, followed by a
\texttt{\{} ... \texttt{\};} block containing the node's properties
and subnodes. Properties are given as just {\emph{name} \texttt{=}
\emph{value}\texttt{;}}. The property values can be given in any
of three forms:
\begin{itemize}
\item \emph{string} (for example, \texttt{"MyBoard"}). The property
value is the given string, including terminating NULL. C-style
escapes (\verb+\t+, \verb+\n+, \verb+\0+ and so forth) are allowed.
\item \emph{cells} (for example, \texttt{<0 8000 f0000000>}). The
property value is made up of a list of 32-bit ``cells'', each given
as a hex value.
\item \emph{bytestring} (for example, \texttt{[1234abcdef]}). The
property value is given as a hex bytestring.
\end{itemize}
Cell properties can also contain \emph{references}. Instead of a hex
number, the source can give an ampersand (\texttt{\&}) followed by the
full path to some node in the tree. For example, in Figure
\ref{fig:dts}, the \texttt{/chosen} node has an
\texttt{interrupt-controller} property referring to the interrupt
controller described by the node \texttt{/mpic@0x3fffdd08400}. In the
output tree, the value of the referenced node's phandle is included in
the property. If that node doesn't have an explicit phandle property,
\dtc will automatically create a unique phandle for it. This approach
makes it easy to create interrupt trees without having to explicitly
assign and remember phandles for the various interrupt controller
nodes.
The \dtc source can also include ``labels'', which are placed on a
particular node or property. For example, Figure \ref{fig:dts} has a
label ``\texttt{memreg}'' on the \texttt{reg} property of the node
\texttt{/memory@0}. When using assembler output, corresponding labels
in the output are generated, which will assemble into symbols
addressing the part of the blob with the node or property in question.
This is useful for the common case where an embedded board has an
essentially fixed device tree with a few variable properties, such as
the size of memory. The bootloader for such a board can have a device
tree linked in, including a symbol referring to the right place in the
blob to update the parameter with the correct value determined at
runtime.
\subsection{Tree checking}
Between reading in the device tree and writing it out in the new
format, \dtc performs a number of checks on the tree:
\begin{itemize}
\item \emph{syntactic structure}: \dtc checks that node and property
names contain only allowed characters and meet length restrictions.
It checks that a node does not have multiple properties or subnodes
with the same name.
\item \emph{semantic structure}: In some cases, \dtc checks that
properties whose contents are defined by convention have appropriate
values. For example, it checks that \texttt{reg} properties have a
length that makes sense given the address forms specified by the
\texttt{\#address-cells} and \texttt{\#size-cells} properties. It
checks that properties such as \texttt{interrupt-parent} contain a
valid phandle.
\item \emph{Linux requirements}: \dtc checks that the device tree
contains those nodes and properties that are required by the Linux
kernel to boot correctly.
\end{itemize}
These checks are useful to catch simple problems with the device tree,
rather than having to debug the results on an embedded kernel. With
the blob input mode, it can also be used for diagnosing problems with
an existing blob.
\section{Future Work}
\subsection{Board ports}
The flattened device tree has always been the only supported way to
boot a \texttt{ppc64} kernel on an embedded system. With the merge of
\texttt{ppc32} and \texttt{ppc64} code it has also become the only
supported way to boot any merged \texttt{powerpc} kernel, 32-bit or
64-bit. In fact, the old \texttt{ppc} architecture exists mainly just
to support the old ppc32 embedded ports that have not been migrated
to the flattened device tree approach. We plan to remove the
\texttt{ppc} architecture eventually, which will mean porting all the
various embedded boards to use the flattened device tree.
\subsection{\dtc features}
While it is already quite usable, there are a number of extra features
that \dtc could include to make creating device trees more convenient:
\begin{itemize}
\item \emph{better tree checking}: Although \dtc already performs a
number of checks on the device tree, they are rather haphazard. In
many cases \dtc will give up after detecting a minor error early and
won't pick up more interesting errors later on. There is a
\texttt{-f} parameter that forces \dtc to generate an output tree
even if there are errors. At present, this needs to be used more
often than one might hope, because \dtc is bad at deciding which
errors should really be fatal, and which rate mere warnings.
\item \emph{binary include}: Occasionally, it is useful for the device
tree to incorporate as a property a block of binary data for some
board-specific purpose. For example, many of Apple's device trees
incorporate bytecode drivers for certain platform devices. \dtc's
source format ought to allow this by letting a property's value be
read directly from a binary file.
\item \emph{macros}: it might be useful for \dtc to implement some
sort of macros so that a tree containing a number of similar devices
(for example, multiple identical ethernet controllers or PCI buses)
can be written more quickly. At present, this can be accomplished
in part by running the source file through CPP before compiling with
\dtc. It's not clear whether ``native'' support for macros would be
more useful.

Device Tree Source Format (version 1)
=====================================
The Device Tree Source (DTS) format is a textual representation of a
device tree in a form that can be processed by dtc into a binary
device tree in the form expected by the kernel. The description below
is not a formal syntax definition of DTS, but describes the basic
constructs used to represent device trees.
Node and property definitions
-----------------------------
Device tree nodes are defined with a node name and unit address with
braces marking the start and end of the node definition. They may be
preceded by a label.
[label:] node-name[@unit-address] {
[properties definitions]
[child nodes]
}
Nodes may contain property definitions and/or child node
definitions. If both are present, properties must come before child
nodes.
Property definitions are name value pairs in the form:
[label:] property-name = value;
except for properties with empty (zero length) value which have the
form:
[label:] property-name;
Property values may be defined as an array of 8, 16, 32, or 64-bit integer
elements, as NUL-terminated strings, as bytestrings or a combination of these.
* Arrays are represented by angle brackets surrounding a space separated list
of C-style integers or character literals. Array elements default to 32-bits
in size. An array of 32-bit elements is also known as a cell list or a list
of cells. A cell being an unsigned 32-bit integer.
e.g. interrupts = <17 0xc>;
* A 64-bit value can be represented with two 32-bit elements.
e.g. clock-frequency = <0x00000001 0x00000000>;
* The storage size of an element can be changed using the /bits/ prefix. The
/bits/ prefix allows for the creation of 8, 16, 32, and 64-bit elements.
The resulting array will not be padded to a multiple of the default 32-bit
element size.
e.g. interrupts = /bits/ 8 <17 0xc>;
e.g. clock-frequency = /bits/ 64 <0x0000000100000000>;
* A NUL-terminated string value is represented using double quotes
(the property value is considered to include the terminating NUL
character).
e.g. compatible = "simple-bus";
* A bytestring is enclosed in square brackets [] with each byte
represented by two hexadecimal digits. Spaces between each byte are
optional.
e.g. local-mac-address = [00 00 12 34 56 78]; or equivalently
local-mac-address = [000012345678];
* Values may have several comma-separated components, which are
concatenated together.
e.g. compatible = "ns16550", "ns8250";
example = <0xf00f0000 19>, "a strange property format";
* In an array a reference to another node will be expanded to that node's
phandle. References may by '&' followed by a node's label:
e.g. interrupt-parent = < &mpic >;
or they may be '&' followed by a node's full path in braces:
e.g. interrupt-parent = < &{/soc/interrupt-controller@40000} >;
References are only permitted in arrays that have an element size of
32-bits.
* Outside an array, a reference to another node will be expanded to that
node's full path.
e.g. ethernet0 = &EMAC0;
* Labels may also appear before or after any component of a property
value, or between elements of an array, or between bytes of a bytestring.
e.g. reg = reglabel: <0 sizelabel: 0x1000000>;
e.g. prop = [ab cd ef byte4: 00 ff fe];
e.g. str = start: "string value" end: ;
File layout
-----------
Version 1 DTS files have the overall layout:
/dts-v1/;
[memory reservations]
/ {
[property definitions]
[child nodes]
};
* The "/dts-v1/;" must be present to identify the file as a version 1
DTS (dts files without this tag will be treated by dtc as being in
the obsolete "version 0", which uses a different format for integers
amongst other small but incompatible changes).
* Memory reservations define an entry for the device tree blob's
memory reservation table. They have the form:
e.g. /memreserve/ <address> <length>;
Where <address> and <length> are 64-bit C-style integers.
* The / { ... }; section defines the root node of the device tree.
* C style (/* ... */) and C++ style (// ...) comments are supported.

and CCed to <devicetree-compiler@vger.kernel.org>.
2) Description
The Device Tree Compiler, dtc, takes as input a device-tree in
a given format and outputs a device-tree in another format.
Typically, the input format is "dts", a human readable source
format, and creates a "dtb", or binary format as output.
The currently supported Input Formats are:
- "dtb": "blob" format. A flattened device-tree block with
header in one binary blob.
- "dts": "source" format. A text file containing a "source"
for a device-tree.
- "fs" format. A representation equivalent to the output of
/proc/device-tree where nodes are directories and
properties are files.
The currently supported Output Formats are:
- "dtb": "blob" format
- "dts": "source" format
- "asm": assembly language file. A file that can be sourced
by gas to generate a device-tree "blob". That file can
then simply be added to your Makefile. Additionally, the
assembly file exports some symbols that can be used.
3) Command Line
The syntax of the dtc command line is:
dtc [options] [<input_filename>]
Options:
<input_filename>
The name of the input source file. If no <input_filename>
or "-" is given, stdin is used.
-b <number>
Set the physical boot cpu.
-f
Force. Try to produce output even if the input tree has errors.
-h
Emit a brief usage and help message.
-I <input_format>
The source input format, as listed above.
-o <output_filename>
The name of the generated output file. Use "-" for stdout.
-O <output_format>
The generated output format, as listed above.
-d <dependency_filename>
Generate a dependency file during compilation.
-q
Quiet: -q suppress warnings, -qq errors, -qqq all
-R <number>
Make space for <number> reserve map entries
Relevant for dtb and asm output only.
-@
Generates a __symbols__ node at the root node of the resulting blob
for any node labels used, and for any local references using phandles
it also generates a __local_fixups__ node that tracks them.
When using the /plugin/ tag all unresolved label references to
be tracked in the __fixups__ node, making dynamic resolution possible.
-A
Generate automatically aliases for all node labels. This is similar to
the -@ option (the __symbols__ node contain identical information) but
the semantics are slightly different since no phandles are automatically
generated for labeled nodes.
-S <bytes>
Ensure the blob at least <bytes> long, adding additional
space if needed.
-v
Print DTC version and exit.
-V <output_version>
Generate output conforming to the given <output_version>.
By default the most recent version is generated.
Relevant for dtb and asm output only.
The <output_version> defines what version of the "blob" format will be
generated. Supported versions are 1, 2, 3, 16 and 17. The default is
always the most recent version and is likely the highest number.
Additionally, dtc performs various sanity checks on the tree.
4) Device Tree Source file
4.1) Overview
Here is a very rough overview of the layout of a DTS source file:
sourcefile: versioninfo plugindecl list_of_memreserve devicetree
memreserve: label 'memreserve' ADDR ADDR ';'
| label 'memreserve' ADDR '-' ADDR ';'
devicetree: '/' nodedef
versioninfo: '/' 'dts-v1' '/' ';'
plugindecl: '/' 'plugin' '/' ';'
| /* empty */
nodedef: '{' list_of_property list_of_subnode '}' ';'
property: label PROPNAME '=' propdata ';'
propdata: STRING
| '<' list_of_cells '>'
| '[' list_of_bytes ']'
subnode: label nodename nodedef
That structure forms a hierarchical layout of nodes and properties
rooted at an initial node as:
/ {
}
Both classic C style and C++ style comments are supported.
Source files may be directly included using the syntax:
/include/ "filename"
4.2) Properties
Properties are named, possibly labeled, values. Each value
is one of:
- A null-teminated C-like string,
- A numeric value fitting in 32 bits,
- A list of 32-bit values
- A byte sequence
Here are some example property definitions:
- A property containing a 0 terminated string
property1 = "string_value";
- A property containing a numerical 32-bit hexadecimal value
property2 = <1234abcd>;
- A property containing 3 numerical 32-bit hexadecimal values
property3 = <12345678 12345678 deadbeef>;
- A property whose content is an arbitrary array of bytes
property4 = [0a 0b 0c 0d de ea ad be ef];
Node may contain sub-nodes to obtain a hierarchical structure.
For example:
- A child node named "childnode" whose unit name is
"childnode at address". It in turn has a string property
called "childprop".
childnode@addresss {
childprop = "hello\n";
};
By default, all numeric values are hexadecimal. Alternate bases
may be specified using a prefix "d#" for decimal, "b#" for binary,
and "o#" for octal.
Strings support common escape sequences from C: "\n", "\t", "\r",
"\(octal value)", "\x(hex value)".
4.3) Labels and References
Labels may be applied to nodes or properties. Labels appear
before a node name, and are referenced using an ampersand: &label.
Absolute node path names are also allowed in node references.
In this exmaple, a node is labled "mpic" and then referenced:
mpic: interrupt-controller@40000 {
...
};
ethernet-phy@3 {
interrupt-parent = <&mpic>;
...
};
And used in properties, lables may appear before or after any value:
randomnode {
prop: string = data: "mystring\n" data_end: ;
...
};
II - The DT block format
========================
This chapter defines the format of the flattened device-tree
passed to the kernel. The actual content of the device tree
are described in the kernel documentation in the file
linux-2.6/Documentation/powerpc/booting-without-of.txt
You can find example of code manipulating that format within
the kernel. For example, the file:
including arch/powerpc/kernel/prom_init.c
will generate a flattened device-tree from the Open Firmware
representation. Other utilities such as fs2dt, which is part of
the kexec tools, will generate one from a filesystem representation.
Some bootloaders such as U-Boot provide a bit more support by
using the libfdt code.
For booting the kernel, the device tree block has to be in main memory.
It has to be accessible in both real mode and virtual mode with no
mapping other than main memory. If you are writing a simple flash
bootloader, it should copy the block to RAM before passing it to
the kernel.
1) Header
---------
The kernel is entered with r3 pointing to an area of memory that is
roughly described in include/asm-powerpc/prom.h by the structure
boot_param_header:
struct boot_param_header {
u32 magic; /* magic word OF_DT_HEADER */
u32 totalsize; /* total size of DT block */
u32 off_dt_struct; /* offset to structure */
u32 off_dt_strings; /* offset to strings */
u32 off_mem_rsvmap; /* offset to memory reserve map */
u32 version; /* format version */
u32 last_comp_version; /* last compatible version */
/* version 2 fields below */
u32 boot_cpuid_phys; /* Which physical CPU id we're
booting on */
/* version 3 fields below */
u32 size_dt_strings; /* size of the strings block */
/* version 17 fields below */
u32 size_dt_struct; /* size of the DT structure block */
};
Along with the constants:
/* Definitions used by the flattened device tree */
#define OF_DT_HEADER 0xd00dfeed /* 4: version,
4: total size */
#define OF_DT_BEGIN_NODE 0x1 /* Start node: full name
*/
#define OF_DT_END_NODE 0x2 /* End node */
#define OF_DT_PROP 0x3 /* Property: name off,
size, content */
#define OF_DT_END 0x9
All values in this header are in big endian format, the various
fields in this header are defined more precisely below. All "offset"
values are in bytes from the start of the header; that is from the
value of r3.
- magic
This is a magic value that "marks" the beginning of the
device-tree block header. It contains the value 0xd00dfeed and is
defined by the constant OF_DT_HEADER
- totalsize
This is the total size of the DT block including the header. The
"DT" block should enclose all data structures defined in this
chapter (who are pointed to by offsets in this header). That is,
the device-tree structure, strings, and the memory reserve map.
- off_dt_struct
This is an offset from the beginning of the header to the start
of the "structure" part the device tree. (see 2) device tree)
- off_dt_strings
This is an offset from the beginning of the header to the start
of the "strings" part of the device-tree
- off_mem_rsvmap
This is an offset from the beginning of the header to the start
of the reserved memory map. This map is a list of pairs of 64-
bit integers. Each pair is a physical address and a size. The
list is terminated by an entry of size 0. This map provides the
kernel with a list of physical memory areas that are "reserved"
and thus not to be used for memory allocations, especially during
early initialization. The kernel needs to allocate memory during
boot for things like un-flattening the device-tree, allocating an
MMU hash table, etc... Those allocations must be done in such a
way to avoid overriding critical things like, on Open Firmware
capable machines, the RTAS instance, or on some pSeries, the TCE
tables used for the iommu. Typically, the reserve map should
contain _at least_ this DT block itself (header,total_size). If
you are passing an initrd to the kernel, you should reserve it as
well. You do not need to reserve the kernel image itself. The map
should be 64-bit aligned.
- version
This is the version of this structure. Version 1 stops
here. Version 2 adds an additional field boot_cpuid_phys.
Version 3 adds the size of the strings block, allowing the kernel
to reallocate it easily at boot and free up the unused flattened
structure after expansion. Version 16 introduces a new more
"compact" format for the tree itself that is however not backward
compatible. Version 17 adds an additional field, size_dt_struct,
allowing it to be reallocated or moved more easily (this is
particularly useful for bootloaders which need to make
adjustments to a device tree based on probed information). You
should always generate a structure of the highest version defined
at the time of your implementation. Currently that is version 17,
unless you explicitly aim at being backward compatible.
- last_comp_version
Last compatible version. This indicates down to what version of
the DT block you are backward compatible. For example, version 2
is backward compatible with version 1 (that is, a kernel build
for version 1 will be able to boot with a version 2 format). You
should put a 1 in this field if you generate a device tree of
version 1 to 3, or 16 if you generate a tree of version 16 or 17
using the new unit name format.
- boot_cpuid_phys
This field only exist on version 2 headers. It indicate which
physical CPU ID is calling the kernel entry point. This is used,
among others, by kexec. If you are on an SMP system, this value
should match the content of the "reg" property of the CPU node in
the device-tree corresponding to the CPU calling the kernel entry
point (see further chapters for more informations on the required
device-tree contents)
- size_dt_strings
This field only exists on version 3 and later headers. It
gives the size of the "strings" section of the device tree (which
starts at the offset given by off_dt_strings).
- size_dt_struct
This field only exists on version 17 and later headers. It gives
the size of the "structure" section of the device tree (which
starts at the offset given by off_dt_struct).
So the typical layout of a DT block (though the various parts don't
need to be in that order) looks like this (addresses go from top to
bottom):
------------------------------
r3 -> | struct boot_param_header |
------------------------------
| (alignment gap) (*) |
------------------------------
| memory reserve map |
------------------------------
| (alignment gap) |
------------------------------
| |
| device-tree structure |
| |
------------------------------
| (alignment gap) |
------------------------------
| |
| device-tree strings |
| |
-----> ------------------------------
|
|
--- (r3 + totalsize)
(*) The alignment gaps are not necessarily present; their presence
and size are dependent on the various alignment requirements of
the individual data blocks.
2) Device tree generalities
---------------------------
This device-tree itself is separated in two different blocks, a
structure block and a strings block. Both need to be aligned to a 4
byte boundary.
First, let's quickly describe the device-tree concept before detailing
the storage format. This chapter does _not_ describe the detail of the
required types of nodes & properties for the kernel, this is done
later in chapter III.
The device-tree layout is strongly inherited from the definition of
the Open Firmware IEEE 1275 device-tree. It's basically a tree of
nodes, each node having two or more named properties. A property can
have a value or not.
It is a tree, so each node has one and only one parent except for the
root node who has no parent.
A node has 2 names. The actual node name is generally contained in a
property of type "name" in the node property list whose value is a
zero terminated string and is mandatory for version 1 to 3 of the
format definition (as it is in Open Firmware). Version 16 makes it
optional as it can generate it from the unit name defined below.
There is also a "unit name" that is used to differentiate nodes with
the same name at the same level, it is usually made of the node
names, the "@" sign, and a "unit address", which definition is
specific to the bus type the node sits on.
The unit name doesn't exist as a property per-se but is included in
the device-tree structure. It is typically used to represent "path" in
the device-tree. More details about the actual format of these will be
below.
The kernel powerpc generic code does not make any formal use of the
unit address (though some board support code may do) so the only real
requirement here for the unit address is to ensure uniqueness of
the node unit name at a given level of the tree. Nodes with no notion
of address and no possible sibling of the same name (like /memory or
/cpus) may omit the unit address in the context of this specification,
or use the "@0" default unit address. The unit name is used to define
a node "full path", which is the concatenation of all parent node
unit names separated with "/".
The root node doesn't have a defined name, and isn't required to have
a name property either if you are using version 3 or earlier of the
format. It also has no unit address (no @ symbol followed by a unit
address). The root node unit name is thus an empty string. The full
path to the root node is "/".
Every node which actually represents an actual device (that is, a node
which isn't only a virtual "container" for more nodes, like "/cpus"
is) is also required to have a "device_type" property indicating the
type of node .
Finally, every node that can be referenced from a property in another
node is required to have a "linux,phandle" property. Real open
firmware implementations provide a unique "phandle" value for every
node that the "prom_init()" trampoline code turns into
"linux,phandle" properties. However, this is made optional if the
flattened device tree is used directly. An example of a node
referencing another node via "phandle" is when laying out the
interrupt tree which will be described in a further version of this
document.
This "linux, phandle" property is a 32-bit value that uniquely
identifies a node. You are free to use whatever values or system of
values, internal pointers, or whatever to generate these, the only
requirement is that every node for which you provide that property has
a unique value for it.
Here is an example of a simple device-tree. In this example, an "o"
designates a node followed by the node unit name. Properties are
presented with their name followed by their content. "content"
represents an ASCII string (zero terminated) value, while <content>
represents a 32-bit hexadecimal value. The various nodes in this
example will be discussed in a later chapter. At this point, it is
only meant to give you a idea of what a device-tree looks like. I have
purposefully kept the "name" and "linux,phandle" properties which
aren't necessary in order to give you a better idea of what the tree
looks like in practice.
/ o device-tree
|- name = "device-tree"
|- model = "MyBoardName"
|- compatible = "MyBoardFamilyName"
|- #address-cells = <2>
|- #size-cells = <2>
|- linux,phandle = <0>
|
o cpus
| | - name = "cpus"
| | - linux,phandle = <1>
| | - #address-cells = <1>
| | - #size-cells = <0>
| |
| o PowerPC,970@0
| |- name = "PowerPC,970"
| |- device_type = "cpu"
| |- reg = <0>
| |- clock-frequency = <5f5e1000>
| |- 64-bit
| |- linux,phandle = <2>
|
o memory@0
| |- name = "memory"
| |- device_type = "memory"
| |- reg = <00000000 00000000 00000000 20000000>
| |- linux,phandle = <3>
|
o chosen
|- name = "chosen"
|- bootargs = "root=/dev/sda2"
|- linux,phandle = <4>
This tree is almost a minimal tree. It pretty much contains the
minimal set of required nodes and properties to boot a linux kernel;
that is, some basic model informations at the root, the CPUs, and the
physical memory layout. It also includes misc information passed
through /chosen, like in this example, the platform type (mandatory)
and the kernel command line arguments (optional).
The /cpus/PowerPC,970@0/64-bit property is an example of a
property without a value. All other properties have a value. The
significance of the #address-cells and #size-cells properties will be
explained in chapter IV which defines precisely the required nodes and
properties and their content.
3) Device tree "structure" block
The structure of the device tree is a linearized tree structure. The
"OF_DT_BEGIN_NODE" token starts a new node, and the "OF_DT_END_NODE"
ends that node definition. Child nodes are simply defined before
"OF_DT_END_NODE" (that is nodes within the node). A 'token' is a 32
bit value. The tree has to be "finished" with a OF_DT_END token
Here's the basic structure of a single node:
* token OF_DT_BEGIN_NODE (that is 0x00000001)
* for version 1 to 3, this is the node full path as a zero
terminated string, starting with "/". For version 16 and later,
this is the node unit name only (or an empty string for the
root node)
* [align gap to next 4 bytes boundary]
* for each property:
* token OF_DT_PROP (that is 0x00000003)
* 32-bit value of property value size in bytes (or 0 if no
value)
* 32-bit value of offset in string block of property name
* property value data if any
* [align gap to next 4 bytes boundary]
* [child nodes if any]
* token OF_DT_END_NODE (that is 0x00000002)
So the node content can be summarized as a start token, a full path,
a list of properties, a list of child nodes, and an end token. Every
child node is a full node structure itself as defined above.
NOTE: The above definition requires that all property definitions for
a particular node MUST precede any subnode definitions for that node.
Although the structure would not be ambiguous if properties and
subnodes were intermingled, the kernel parser requires that the
properties come first (up until at least 2.6.22). Any tools
manipulating a flattened tree must take care to preserve this
constraint.
4) Device tree "strings" block
In order to save space, property names, which are generally redundant,
are stored separately in the "strings" block. This block is simply the
whole bunch of zero terminated strings for all property names
concatenated together. The device-tree property definitions in the
structure block will contain offset values from the beginning of the
strings block.
III - libfdt
============
This library should be merged into dtc proper.
This library should likely be worked into U-Boot and the kernel.
IV - Utility Tools
==================
1) convert-dtsv0 -- Conversion to Version 1
convert-dtsv0 is a small utility program which converts (DTS)
Device Tree Source from the obsolete version 0 to version 1.
Version 1 DTS files are marked by line "/dts-v1/;" at the top of the file.
The syntax of the convert-dtsv0 command line is:
convert-dtsv0 [<input_filename ... >]
Each file passed will be converted to the new /dts-v1/ version by creating
a new file with a "v1" appended the filename.
Comments, empty lines, etc. are preserved.
2) fdtdump -- Flat Device Tree dumping utility
The fdtdump program prints a readable version of a flat device tree file.
The syntax of the fdtdump command line is:
fdtdump <DTB-file-name>

Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.

Licensing and contribution policy of dtc and libfdt
===================================================
This dtc package contains two pieces of software: dtc itself, and
libfdt which comprises the files in the libfdt/ subdirectory. These
two pieces of software, although closely related, are quite distinct.
dtc does not incoporate or rely on libfdt for its operation, nor vice
versa. It is important that these two pieces of software have
different license conditions.
As the copyright banners in each source file attest, dtc is licensed
under the GNU GPL. The full text of the GPL can be found in the file
entitled 'GPL' which should be included in this package. dtc code,
therefore, may not be incorporated into works which do not have a GPL
compatible license.
libfdt, however, is GPL/BSD dual-licensed. That is, it may be used
either under the terms of the GPL, or under the terms of the 2-clause
BSD license (aka the ISC license). The full terms of that license are
given in the copyright banners of each of the libfdt source files.
This is, in practice, equivalent to being BSD licensed, since the
terms of the BSD license are strictly more permissive than the GPL.
I made the decision to license libfdt in this way because I want to
encourage widespread and correct usage of flattened device trees,
including by proprietary or otherwise GPL-incompatible firmware or
tools. Allowing libfdt to be used under the terms of the BSD license
makes that it easier for vendors or authors of such software to do so.
This does mean that libfdt code could be "stolen" - say, included in a
proprietary fimware and extended without contributing those extensions
back to the libfdt mainline. While I hope that doesn't happen, I
believe the goal of allowing libfdt to be widely used is more
important than avoiding that. libfdt is quite small, and hardly
rocket science; so the incentive for such impolite behaviour is small,
and the inconvenience caused therby is not dire.
Licenses such as the LGPL which would allow code to be used in non-GPL
software, but also require contributions to be returned were
considered. However, libfdt is designed to be used in firmwares and
other environments with unusual technical constraints. It's difficult
to anticipate all possible changes which might be needed to meld
libfdt into such environments and so difficult to suitably word a
license that puts the boundary between what is and isn't permitted in
the intended place. Again, I judged encouraging widespread use of
libfdt by keeping the license terms simple and familiar to be the more
important goal.
**IMPORTANT** It's intended that all of libfdt as released remain
permissively licensed this way. Therefore only contributions which
are released under these terms can be merged into the libfdt mainline.

reference to a regular object.

each operation. We had already left room for it, but previously
plugged it only on a call to c_str(), but the WG changed the
requirement when I wasn't looking. (Can't leave them alone for
a second without they break something else.)
* bits/valarray_meta.h: add Gaby's changes from 981018.
* src/locale.cc: add new type _Bad_use_facet to be thrown on
failure of use_facet<>().

* src/locale-inst.cc: Don't instantiate time_get for
ostreambuf_iterators as time_get::do_get_weekday and
time_get::do_get_monthname use __match_parallel, which is illegal
for ostreambuf_iterators to use, as they don't have operator== or
operator!=.

Use stl/bits/std_stdexcept.h instead of this file?

(class istream_iterator): Make the new operator!= a friend also.
* stl/bits/stl_config.h: Define __STL_HAS_WCHAR_T,
__STL_MEMBER_TEMPLATE_CLASSES, and __STL_LONG_LONG. Don't include
_G_config.h like the egcs one does.
1998-09-01 Brendan Kehoe <brendan@cygnus.com>
* bits/string.tcc: Call `_M_destroy' instead of `destroy'.
* bits/valarray_meta.h: Throughout, rename _Expr typedefs to be
_Expr1 (or _Expr_def if it's taken), and change definitions.
Avoids redecl of the template parm.
* bits/string.tcc (basic_string copy ctor): Fix typo in declaration.
(operator>>): Initialize __ERROR with ios_base::goodbit, not 0.
* bits/std_streambuf.h (_POSIX_SOURCE): Only define if it's not
already done.
* src/locale-inst.cc: New file, **TOTAL HACK**. There has GOT to
be a better way to do this.
* src/stlinst.cc: New file.
* BUGS: New file, with various discovered bugs that need to be
fixed.
* Makefile.in, math/Makefile.in, string/Makefile.in,
src/Makefile.in: Reran automake.
Workarounds, these may not all be the final fixes:
* bits/basic_ios.h (class basic_ios): Make _M_strbuf be protected,
not private, for basic_istream::get() in std_istream.h to be able
to use it.
(basic_ios::operator void*): Don't use static_cast for the false
case.
(basic_ios::copyfmt): Fix `rhs.except' to be `rhs.exceptions ()'.
This appears to have been in sep94, but didn't get corrected
afterwards.
* bits/basic_string.h (npos): Don't init here.
* bits/string.tcc: Instead, do initialization here, to -1 instead
of the size_type destructor.
* src/traits.cc, src/wtraits.cc: New files.
* bits/char_traits.h: For char_traits<char> and
char_traits<wchar_t>, declare static, but define over in the src
files.
* bits/gslice.h: Comment out forward decls of _Array, valarray,
gslice_array, and _GsliceExpression.
* bits/std_cstdio.h [__sparc__ && __svr4__]: #undef all of
clearerr, feof, ferror, getc, getchar, putc, putchar, stdin,
stdout, and stderr. Note we do get unresolved refs to stdin, but
that'll get fixed by the "true" solution.
* bits/std_ios.h: Include <bits/std_streambuf.h> to get the
definition of basic_streambuf.h, which is used in basic_ios.h to
call pubimbue.
* bits/std_streambuf.h: Don't include libio.h for now.
(class basic_streambuf): Define missing methods pubimbue and
getloc.
* src/Makefile.am (libstdc___la_SOURCES): Add stdexcept.cc,
ios.cc, os_raw.cc, stdstreams.cc, locale.cc, localename.cc,
locale-inst.cc, stlinst.cc, traits.cc, wtraits.cc.
* src/ios.cc: Instantiate basic_ios<char> and basic_ios<wchar_t>.
* src/locale.cc: Come up with munged versions of _S_toupper,
_S_tolower, and _S_table instead of the glibc-specific ones, so
they're at least defined, if not necessarily usable. The glibc
ones on any other system will yield unresolved refs to
__ctype_{b,toupper,tolower}.
* src/string.cc: Define all of ADDCS, ADDPS, et al. Add
basic_ios, basic_istream, basic_ostream. Don't do char_traits
anymore cuz of the explicit specialization in char_traits.h.
Also add _S_string_copy, but this doesn't fix it -- cf the BUGS
file for the details.
* stl/bits/stl_algobase.h (equal): Fix to do `! (x==y)'.
* stl/bits/stl_iterator.h (__distance): Likewise.
* stl/bits/stl_iterator.h: As with 8/18 set, define missing op!=,
op>, op<=, and op>= for reverse_iterator. Also add op!= for
istream_iterator.
1998-08-26 Brendan Kehoe <brendan@cygnus.com>
* bits/string.tcc (basic_string::compare (const char*)): Fix to
return 0, not 1.
1998-08-25 Brendan Kehoe <brendan@cygnus.com>
This should really be fixed with __asm__ directives renaming the
symbol, but keeping the function.
* math/clogf.c (c_logf): Renamed from `clogf'.
* math/clogl.c (c_logl): Renamed from `clogl'.
* math/complex-stub.h (c_logf, c_logl): Change decls.
* bits/locfacets.h (class _Numeric_get): For friend decls, rename
_CharT and _InIter parms, since they duplicate the enclosing ones.
1998-08-19 Brendan Kehoe <brendan@cygnus.com>
Deal with conflict of the iostreams `clog' and our internal
complex number `clog'.
* src/complex.cc: Call `c_log' instead of `clog'.
* math/clog.c (c_log):: Renamed from clog.
* math/complex-stub.h (c_log): Renamed from clog decl.
* bits/locfacets.h (class _Numeric_get): Tweak fwd decls of the
get/put classes.
(num_put::put): #if 0 long long version, since we don't declare or
define the long long version of do_put.
1998-08-18 Nathan Myers <ncm@cantrip.org>
* bits/basic_string.h: add basic_string<>::push_back(), fix return
type of get_allocator (thanks to Ryszard Kabatek).
* bits/char_traits.h: make init order of fpos<> members
match decl order.
* bits/ios_base.h: fix decls of ios_base bitmask & enum types, add
flags _S_fd_in etc. for special filebuf ctor.
* bits/locfacets.h: make _Numeric_get and _Format_cache public
to work around problems in friend declarations.
* bits/locfacets.tcc: qualify _S_get_cache in num_get<>::get(..bool&),
fix random type errors & typos
* bits/std_fstream.h: major refitting to bypass libio (for now),
instrument to use bits/fstream.tcc template definitions
* bits/std_iosfwd.h: mess with wrappers
* bits/std_istream.h: remove meaningless comment
* bits/std_ostream.h: instrument to work with ostream.tcc.
* bits/std_streambuf.h: instrument to work with streambuf.tcc
* bits/fstream.tcc: template defs for <fstream>
* bits/ostream.tcc: template defs for <ostream>
* bits/streambuf.tcc: template defs for <streambuf>
* bits/os_raw.h: thin OS interface wrapper, to bypass libio (for now).
* Delete .cc files, replace with bits/*.tcc
src/fstream.cc
src/istream.cc
src/ostream.cc
src/streambuf.cc
* Add files:
src/os_raw.cc: thin interface to OS, to bypass libio (for now).
src/stdstreams.cc: cout, cin, etc. definitions
(these still need work: must be init'd before user statics.)

file: libstdc++-v3/README
New users may wish to point their web browsers to the file
documentation.html in the 'docs/html' subdirectory. It contains brief
building instructions and notes on how to configure the library in
interesting ways.
Instructions for configuring and building appear in
docs/html/install.html.
This directory contains the files needed to create an ISO Standard C++
Library.
It has subdirectories:
docs
Files in HTML and text format that document usage, quirks of the
implementation, and contributor checklists.
include
All header files for the C++ library are within this directory,
modulo specific runtime-related files that are in the libsupc++
directory.
include/std
Files meant to be found by #include <name> directives in
standard-conforming user programs.
include/c
Headers intended to directly include standard C headers.
[NB: this can be enabled via --enable-cheaders=c]
include/c_std
Headers intended to include standard C headers, and put select
names into the std:: namespace.
[NB: this is the default, and is the same as --enable-cheaders=c_std]
include/bits
Files included by standard headers and by other files in
the bits directory.
include/backward
Headers provided for backward compatibility, such as <iostream.h>.
They are not used in this library.
include/ext
Headers that define extensions to the standard library. No
standard header refers to any of them.
scripts
Scripts that are used during the configure, build, make, or test
process.
src
Files that are used in constructing the library, but are not
installed.
testsuites/[backward, demangle, ext, performance, thread, 17_* to 27_*]
Test programs are here, and may be used to begin to exercise the
library. Support for "make check" and "make check-install" is
complete, and runs through all the subdirectories here when this
command is issued from the build directory. Please note that
"make check" requires DejaGNU 1.4 or later to be installed. Please
note that "make check-script" calls the script mkcheck, which
requires bash, and which may need the paths to bash adjusted to
work properly, as /bin/bash is assumed.
Other subdirectories contain variant versions of certain files
that are meant to be copied or linked by the configure script.
Currently these are:
config/abi
config/cpu
config/io
config/locale
config/os
In addition, two subdirectories are convenience libraries:
libmath
Support routines needed for C++ math. Only needed if the
underlying "C" implementation is non-existent, in particular
required or optimal long double, long long, and C99 functionality.
libsupc++
Contains the runtime library for C++, including exception
handling and memory allocation and deallocation, RTTI, terminate
handlers, etc.
Note that glibc also has a bits/ subdirectory. We will either
need to be careful not to collide with names in its bits/
directory; or rename bits to (e.g.) cppbits/.
In files throughout the system, lines marked with an "XXX" indicate
a bug or incompletely-implemented feature. Lines marked "XXX MT"
indicate a place that may require attention for multi-thread safety.

# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
#
# Of course, Automake must honor this variable whenever it calls a
# tool from the auxiliary directory. The problem is that $srcdir (and
# therefore $ac_aux_dir as well) can be either absolute or relative,
# depending on how configure is run. This is pretty annoying, since
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
# source directory, any form will work fine, but in subdirectories a
# relative path needs to be adjusted first.
#
# $ac_aux_dir/missing
# fails when called from a subdirectory if $ac_aux_dir is relative
# $top_srcdir/$ac_aux_dir/missing
# fails if $ac_aux_dir is absolute,
# fails when called from a subdirectory in a VPATH build with
# a relative $ac_aux_dir
#
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
# are both prefixed by $srcdir. In an in-source build this is usually
# harmless because $srcdir is `.', but things will broke when you
# start a VPATH build or use an absolute $srcdir.
#
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
# and then we would define $MISSING as
# MISSING="\${SHELL} $am_aux_dir/missing"
# This will work as long as MISSING is not called from configure, because
# unfortunately $(top_srcdir) has no meaning in configure.
# However there are other variables, like CC, which are often used in
# configure, and could therefore not use this "fixed" $ac_aux_dir.
#
# Another solution, used here, is to always expand $ac_aux_dir to an
# absolute PATH. The drawback is that using absolute paths prevent a
# configured tree to be moved without reconfiguration.

# installer happens to have an overly restrictive umask (e.g. 077).
# This was a mistake. There are at least two reasons why we must not
# use `-m 0755':
# - it causes special bits like SGID to be ignored,
# - it may be too restrictive (some setups expect 775 directories).
#
# Do not use -m 0755 and let people choose whatever they expect by
# setting umask.
#
# We cannot accept any implementation of `mkdir' that recognizes `-p'.
# Some implementations (such as Solaris 8's) are not thread-safe: if a
# parallel make tries to run `mkdir -p a/b' and `mkdir -p a/c'
# concurrently, both version can detect that a/ is missing, but only
# one can create it and the other will error out. Consequently we
