gpsd: Add patch to enable + configure PPS in TSIP (trimble) driver

In the sysmoBTS 2050, we want to configure the 1PPS output of the
trimble to be active only if it has at least 1 satellite in view,
and want to make the receiver output its time information in UTC,
rather than GPS time.

+     
+     Disk /dev/mmcblk0: 3951 MB, 3951034368 bytes

+     # mke2fs -j -L "root" /dev/mmcblk0p2
 
-  2. Use the "dd" utility to write the image to the SD card. For example:
+  The following assumes the SD card partition 1 and 2 are mounted at
+  /media/boot and /media/root respectively. Removing the card and reinserting
+  it will do just that on most modern Linux desktop environments.
+  
+  The files referenced below are made available after the build in

+
+  4. Install the kernel uImage
+     # cp uImage-beagleboard.bin /media/boot/uImage
+
+  5. Prepare a u-boot script to simplify the boot process
+     The Beagleboard can be made to boot at this point from the u-boot command
+     shell. To automate this process, generate a user.scr script as follows.
+
+     Install uboot-mkimage (from uboot-mkimage on Ubuntu or uboot-tools on Fedora).
+
+     Prepare a script config:
+
+     # (cat << EOF

+     # cp boot.scr /media/boot
+
+   6. Unmount the SD partitions, insert the SD card into the Beagleboard, and
+      boot the Beagleboard
+
+Note: As of the 2.6.37 linux-yocto kernel recipe, the Beagleboard uses the
+      OMAP_SERIAL device (ttyO2). If you are using an older kernel, such as the
+      2.6.34 linux-yocto-stable, be sure to replace ttyO2 with ttyS2 above. You
+      should also override the machine SERIAL_CONSOLE in your local.conf in
+      order to setup the getty on the serial line:

+only needs 8-16MB, other images will need more.
 
-Load the kernel, and boot the system as follows:
+  # fdisk /dev/sdb
+  Command (m for help): p
 
- 1. Get the kernel (vmlinux) file from the tmp/deploy/images/edgerouter
-    directory, and make them available on your TFTP server.
+  Disk /dev/sdb: 4011 MB, 4011491328 bytes
+  124 heads, 62 sectors/track, 1019 cylinders, total 7834944 sectors
+  Units = sectors of 1 * 512 = 512 bytes
+  Sector size (logical/physical): 512 bytes / 512 bytes
+  I/O size (minimum/optimal): 512 bytes / 512 bytes
+  Disk identifier: 0x0009e87d
 
- 2. Connect the board's first serial port to your workstation and then start up
-    your favourite serial terminal so that you will be able to interact with
-    the serial console. If you don't have a favourite, picocom is suggested:
+     Device Boot      Start         End      Blocks   Id  System
+  /dev/sdb1              62     1952751      976345   83  Linux
 
-  $ picocom /dev/ttyS0 -b 115200
+3) Format partition 1 on the USB as ext3
 
- 3. Power up or reset the board and press a key on the terminal when prompted
-    to get to the U-Boot command line
+  # mke2fs -j /dev/sdb1
 
- 4. Set up the environment in U-Boot:
+4) Mount partition 1 and then extract the contents of
+tmp/deploy/images/core-image-XXXX.tar.bz2 into it (preserving permissions).
 
- => setenv ipaddr <board ip>
- => setenv serverip <tftp server ip>
+  # mount /dev/sdb1 /media/sdb1
+  # cd /media/sdb1
+  # tar -xvjpf tmp/deploy/images/core-image-XXXX.tar.bz2
 
- 5. Download the kernel and boot:
+5) Unmount the USB drive and then plug it into the board's USB port
 
- => tftp tftp $loadaddr vmlinux
- => bootoctlinux $loadaddr coremask=0x3 root=/dev/nfs rw nfsroot=<nfsroot ip>:<rootfs path> ip=<board ip>:<server ip>:<gateway ip>:<netmask>:edgerouter:eth0:off mtdparts=phys_mapped_flash:512k(boot0),512k(boot1),64k@3072k(eeprom)
+6) Connect the board's serial port to your workstation and then start up
+your favourite serial terminal so that you will be able to interact with
+the serial console. If you don't have a favourite, picocom is suggested:
 
---- Booting from USB disk ---
+  $ picocom /dev/ttyUSB0 -b 115200
 
-To boot from the USB disk, you either need to remove it from the edgerouter
-box and populate it from another computer, or use a previously booted NFS
-image and populate from the edgerouter itself.
+7) Connect the network into eth0 (the one that is NOT the 3 port switch). If
+you are using power-over-ethernet then the board will power up at this point.
 
-Type 1: Use partitioned image
------------------------------
+8) Start up the board, watch the serial console. Hit Ctrl+C to abort the
+autostart if the board is configured that way (it is by default). The
+bootloader's fconfig command can be used to disable autostart and configure
+the IP settings if you need to change them (default IP is 192.168.1.20).
 
-Steps:
+9) Make the kernel (tmp/deploy/images/vmlinux-routerstationpro.bin) available
+on the tftp server.
 
- 1. Remove the USB disk from the edgerouter and insert it into a computer
-    that has access to your build artifacts.
+10) If you are going to write the kernel to flash (optional - see "Booting a
+kernel directly" below for the alternative), remove the current kernel and
+rootfs flash partitions. You can list the partitions using the following
+bootloader command:
 
- 2. Flash the image.
+  RedBoot> fis list
 
-    # dd if=core-image-minimal-edgerouter.wic of=/dev/sdb
+You can delete the existing kernel and rootfs with these commands:
 
- 3. Insert USB disk into the edgerouter and boot it.
+  RedBoot> fis delete kernel
+  RedBoot> fis delete rootfs
 
-Type 2: NFS
------------
+--- Booting a kernel directly ---
 
-Note: If you place the kernel on the ext3 partition, you must re-create the
-      ext3 filesystem, since the factory u-boot can only handle 128 byte inodes and
-      cannot read the partition otherwise.
+1) Load the kernel using the following bootloader command:
 
-      These boot instructions assume that you have recreated the ext3 filesystem with
-      128 byte inodes, you have an updated uboot or you are running and image capable
-      of making the filesystem on the board itself.
+  RedBoot> load -m tftp -h <ip of tftp server> vmlinux-routerstationpro.bin
 
+You should see a message on it being successfully loaded.
 
- 1. Boot from NFS root
+2) Execute the kernel:
 
- 2. Mount the USB disk partition 2 and then extract the contents of
-    tmp/deploy/core-image-XXXX.tar.bz2 into it.
+  RedBoot> exec -c "console=ttyS0,115200 root=/dev/sda1 rw rootdelay=2 board=UBNT-RSPRO"
 
-    Before starting, copy core-image-minimal-xxx.tar.bz2 and vmlinux into
-    rootfs path on your workstation.
+Note that specifying the command line with -c is important as linux-yocto does
+not provide a default command line.
 
-    and then,
-  
-      # mount /dev/sda2 /media/sda2
-      # tar -xvjpf core-image-minimal-XXX.tar.bz2 -C /media/sda2
-      # cp vmlinux /media/sda2/boot/vmlinux
-      # umount /media/sda2
-      # reboot
+--- Writing a kernel to flash ---
 
- 3. Reboot the board and press a key on the terminal when prompted to get to the U-Boot
-    command line:
+1) Go to your tftp server and gzip the kernel you want in flash. It should
+halve the size.
 
-    # reboot
+2) Load the kernel using the following bootloader command:
 
- 4. Load the kernel and boot:
+  RedBoot> load -r -b 0x80600000 -m tftp -h <ip of tftp server> vmlinux-routerstationpro.bin.gz
+
+This should output something similar to the following:
+
+  Raw file loaded 0x80600000-0x8087c537, assumed entry at 0x80600000
+
+Calculate the length by subtracting the first number from the second number
+and then rounding the result up to the nearest 0x1000.
+
+3) Using the length calculated above, create a flash partition for the kernel:
+
+  RedBoot> fis create -b 0x80600000 -l 0x240000 kernel
+
+(change 0x240000 to your rounded length -- change "kernel" to whatever
+you want to name your kernel)
+
+--- Booting a kernel from flash ---
+
+To boot the flashed kernel perform the following steps.
+
+1) At the bootloader prompt, load the kernel:
+
+  RedBoot> fis load -d -e kernel
+
+(Change the name "kernel" above if you chose something different earlier)
+
+(-e means 'elf', -d 'decompress')
+
+2) Execute the kernel using the exec command as above.
+
+--- Automating the boot process ---
+
+After writing the kernel to flash and testing the load and exec commands
+manually, you can automate the boot process with a boot script.
+
+1) RedBoot> fconfig
+   (Answer the questions not specified here as they pertain to your environment)
+2) Run script at boot: true
+  Boot script: 
+  .. fis load -d -e kernel
+  .. exec
+  Enter script, terminate with empty line
+  >> fis load -d -e kernel
+  >> exec -c "console=ttyS0,115200 root=/dev/sda1 rw rootdelay=2 board=UBNT-RSPRO"
+  >> 
+3) Answer the remaining questions and write the changes to flash:
+  Update RedBoot non-volatile configuration - continue (y/n)? y
+  ... Erase from 0xbfff0000-0xc0000000: .
+  ... Program from 0x87ff0000-0x88000000 at 0xbfff0000: .
+4) Power cycle the board.

-# The Makefile has these targets:
-#
-#    pdf:      generates a PDF version of a manual.
-#    html:     generates an HTML version of a manual.

-
-Manual Organization
-===================
-
-Folders exist for individual manuals as follows:
-
-* bitbake-user-manual      - The BitBake User Manual 
-
-Each folder is self-contained regarding content and figures.
-
-If you want to find HTML versions of the BitBake manuals on the web, 
-go to http://www.openembedded.org/wiki/Documentation. 
-
-Makefile
-========
-
-The Makefile processes manual directories to create HTML, PDF,
-tarballs, etc.  Details on how the Makefile work are documented
-inside the Makefile.  See that file for more information.
-
-To build a manual, you run the make command and pass it the name
-of the folder containing the manual's contents. 
-For example, the following command run from the documentation directory 
-creates an HTML and a PDF version of the BitBake User Manual.
-The DOC variable specifies the manual you are making:
-
-     $ make DOC=bitbake-user-manual
-
-template
-========
-Contains various templates, fonts, and some old PNG files.
-
-tools

-    <title>Execution</title>
-
-    <para>
-        The primary purpose for running BitBake is to produce some kind
-        of output such as a single installable package, a kernel, a software
-        development kit, or even a full, board-specific bootable Linux image,
-        complete with bootloader, kernel, and root filesystem.
-        Of course, you can execute the <filename>bitbake</filename>
-        command with options that cause it to execute single tasks,
-        compile single recipe files, capture or clear data, or simply
-        return information about the execution environment.
-    </para>
-
-    <para>
-        This chapter describes BitBake's execution process from start
-        to finish when you use it to create an image.
-        The execution process is launched using the following command
-        form:
-        <literallayout class='monospaced'>
-     $ bitbake <replaceable>target</replaceable>
-        </literallayout>
-        For information on the BitBake command and its options,
-        see
-        "<link linkend='bitbake-user-manual-command'>The BitBake Command</link>"
-        section.
-        <note>
-            <para>
-                Prior to executing BitBake, you should take advantage of available
-                parallel thread execution on your build host by setting the
-                <link linkend='var-BB_NUMBER_THREADS'><filename>BB_NUMBER_THREADS</filename></link>
-                variable in your project's <filename>local.conf</filename>
-                configuration file.
-            </para>
-
-            <para>
-                A common method to determine this value for your build host is to run
-                the following:
-                <literallayout class='monospaced'>
-     $ grep processor /proc/cpuinfo
-                </literallayout>
-                This command returns the number of processors, which takes into
-                account hyper-threading.
-                Thus, a quad-core build host with hyper-threading most likely
-                shows eight processors, which is the value you would then assign to
-                <filename>BB_NUMBER_THREADS</filename>.
-            </para>
-
-            <para>
-                A possibly simpler solution is that some Linux distributions
-                (e.g. Debian and Ubuntu) provide the <filename>ncpus</filename> command.

-
-        <para>
-            The first thing BitBake does is parse base configuration
-            metadata.
-            Base configuration metadata consists of your project's
-            <filename>bblayers.conf</filename> file to determine what
-            layers BitBake needs to recognize, all necessary
-            <filename>layer.conf</filename> files (one from each layer),
-            and <filename>bitbake.conf</filename>.
-            The data itself is of various types:
-            <itemizedlist>
-                <listitem><para><emphasis>Recipes:</emphasis>
-                    Details about particular pieces of software.

-        </para>
-
-        <para>
-            The <filename>layer.conf</filename> files are used to
-            construct key variables such as
-            <link linkend='var-BBPATH'><filename>BBPATH</filename></link>

-            directories, respectively.
-            <filename>BBFILES</filename> is used to locate both recipe
-            and recipe append files
-            (<filename>.bb</filename> and <filename>.bbappend</filename>).
-            If there is no <filename>bblayers.conf</filename> file,
-            it is assumed the user has set the <filename>BBPATH</filename>

-        </para>
-
-        <para>
-            Next, the <filename>bitbake.conf</filename> file is located
-            using the <filename>BBPATH</filename> variable that was
-            just constructed.
-            The <filename>bitbake.conf</filename> file may also include other
-            configuration files using the

-            The first four variables in this list relate to how BitBake treats shell
-            environment variables during task execution.
-            By default, BitBake cleans the environment variables and provides tight
-            control over the shell execution environment.
-            However, through the use of these first four variables, you can
-            apply your control regarding the
-            environment variables allowed to be used by BitBake in the shell
-            during execution of tasks.
-            See the
-            "<link linkend='passing-information-into-the-build-task-environment'>Passing Information Into the Build Task Environment</link>"
-            section and the information about these variables in the
-            variable glossary for more information on how they work and
-            on how to use them.
-        </para>
-
-        <para>
-            The base configuration metadata is global
-            and therefore affects all recipes and tasks that are executed.
-        </para>
-
-        <para>
-            BitBake first searches the current working directory for an
-            optional <filename>conf/bblayers.conf</filename> configuration file.
-            This file is expected to contain a
-            <link linkend='var-BBLAYERS'><filename>BBLAYERS</filename></link>
-            variable that is a space-delimited list of 'layer' directories.
-            Recall that if BitBake cannot find a <filename>bblayers.conf</filename>
-            file, then it is assumed the user has set the <filename>BBPATH</filename>
-            and <filename>BBFILES</filename> variables directly in the environment.
-        </para>
-
-        <para>
-            For each directory (layer) in this list, a <filename>conf/layer.conf</filename>
-            file is located and parsed with the
-            <link linkend='var-LAYERDIR'><filename>LAYERDIR</filename></link>
-            variable being set to the directory where the layer was found.
-            The idea is these files automatically set up
-            <link linkend='var-BBPATH'><filename>BBPATH</filename></link>
-            and other variables correctly for a given build directory.
-        </para>
-
-        <para>
-            BitBake then expects to find the <filename>conf/bitbake.conf</filename>
-            file somewhere in the user-specified <filename>BBPATH</filename>.
-            That configuration file generally has include directives to pull
-            in any other metadata such as files specific to the architecture,
-            the machine, the local environment, and so forth.
-        </para>
-
-        <para>
-            Only variable definitions and include directives are allowed
-            in BitBake <filename>.conf</filename> files.
-            Some variables directly influence BitBake's behavior.
-            These variables might have been set from the environment
-            depending on the environment variables previously
-            mentioned or set in the configuration files.
-            The
-            "<link linkend='ref-variables-glos'>Variables Glossary</link>"
-            chapter presents a full list of variables.
-        </para>
-
-        <para>
-            After parsing configuration files, BitBake uses its rudimentary
-            inheritance mechanism, which is through class files, to inherit
-            some standard classes.
-            BitBake parses a class when the inherit directive responsible
-            for getting that class is encountered.
-        </para>
-
-        <para>
-            The <filename>base.bbclass</filename> file is always included.
-            Other classes that are specified in the configuration using the
-            <link linkend='var-INHERIT'><filename>INHERIT</filename></link>
-            variable are also included.
-            BitBake searches for class files in a
-            <filename>classes</filename> subdirectory under
-            the paths in <filename>BBPATH</filename> in the same way as
-            configuration files.
-        </para>
-
-        <para>
-            A good way to get an idea of the configuration files and
-            the class files used in your execution environment is to
-            run the following BitBake command:
-            <literallayout class='monospaced'>
-     $ bitbake -e > mybb.log
-            </literallayout>
-            Examining the top of the <filename>mybb.log</filename>
-            shows you the many configuration files and class files
-            used in your execution environment.
-        </para>
-
-        <note>
-            <para>
-                You need to be aware of how BitBake parses curly braces.
-                If a recipe uses a closing curly brace within the function and
-                the character has no leading spaces, BitBake produces a parsing
-                error.
-                If you use a pair of curly braces in a shell function, the
-                closing curly brace must not be located at the start of the line
-                without leading spaces.
-            </para>
-
-            <para>
-                Here is an example that causes BitBake to produce a parsing
-                error:
-                <literallayout class='monospaced'>
-     fakeroot create_shar() {
-         cat &lt;&lt; "EOF" &gt; ${SDK_DEPLOY}/${TOOLCHAIN_OUTPUTNAME}.sh
-     usage()
-     {
-       echo "test"
-       ###### The following "}" at the start of the line causes a parsing error ######
-     }
-     EOF
-     }
-                </literallayout>
-                Writing the recipe this way avoids the error:
-                <literallayout class='monospaced'>
-     fakeroot create_shar() {
-         cat &lt;&lt; "EOF" &gt; ${SDK_DEPLOY}/${TOOLCHAIN_OUTPUTNAME}.sh
-     usage()
-     {
-       echo "test"
-       ######The following "}" with a leading space at the start of the line avoids the error ######
-      }
-     EOF
-     }

-            During the configuration phase, BitBake will have set
-            <link linkend='var-BBFILES'><filename>BBFILES</filename></link>.
-            BitBake now uses it to construct a list of recipes to parse,
-            along with any append files (<filename>.bbappend</filename>)
-            to apply.
-            <filename>BBFILES</filename> is a space-separated list of
-            available files and supports wildcards.
-            An example would be:
-            <literallayout class='monospaced'>
-     BBFILES = "/path/to/bbfiles/*.bb /path/to/appends/*.bbappend"
-            </literallayout>
-            BitBake parses each recipe and append file located
-            with <filename>BBFILES</filename> and stores the values of
-            various variables into the datastore.
-            <note>
-                Append files are applied in the order they are encountered in
-                <filename>BBFILES</filename>.
-            </note>
-            For each file, a fresh copy of the base configuration is
-            made, then the recipe is parsed line by line.
-            Any inherit statements cause BitBake to find and
-            then parse class files (<filename>.bbclass</filename>)
-            using
-            <link linkend='var-BBPATH'><filename>BBPATH</filename></link>
-            as the search path.
-            Finally, BitBake parses in order any append files found in
-            <filename>BBFILES</filename>.
-        </para>
-
-        <para>
-            One common convention is to use the recipe filename to define
-            pieces of metadata.
-            For example, in <filename>bitbake.conf</filename> the recipe
-            name and version are used to set the variables
-            <link linkend='var-PN'><filename>PN</filename></link> and
-            <link linkend='var-PV'><filename>PV</filename></link>:
-            <literallayout class='monospaced'>
-     PN = "${@bb.parse.BBHandler.vars_from_file(d.getVar('FILE', False),d)[0] or 'defaultpkgname'}"
-     PV = "${@bb.parse.BBHandler.vars_from_file(d.getVar('FILE', False),d)[1] or '1.0'}"
-            </literallayout>
-            In this example, a recipe called "something_1.2.3.bb" would set
-            <filename>PN</filename> to "something" and
-            <filename>PV</filename> to "1.2.3".
-        </para>
-
-        <para>
-            By the time parsing is complete for a recipe, BitBake
-            has a list of tasks that the recipe defines and a set of
-            data consisting of keys and values as well as
-            dependency information about the tasks.
-        </para>
-
-        <para>
-            BitBake does not need all of this information.
-            It only needs a small subset of the information to make
-            decisions about the recipe.
-            Consequently, BitBake caches the values in which it is
-            interested and does not store the rest of the information.
-            Experience has shown it is faster to re-parse the metadata than to
-            try and write it out to the disk and then reload it.
-        </para>
-
-        <para>
-            Where possible, subsequent BitBake commands reuse this cache of
-            recipe information.
-            The validity of this cache is determined by first computing a
-            checksum of the base configuration data (see
-            <link linkend='var-BB_HASHCONFIG_WHITELIST'><filename>BB_HASHCONFIG_WHITELIST</filename></link>)
-            and then checking if the checksum matches.
-            If that checksum matches what is in the cache and the recipe
-            and class files have not changed, Bitbake is able to use
-            the cache.
-            BitBake then reloads the cached information about the recipe
-            instead of reparsing it from scratch.
-        </para>

-        <para>
-            Recipe file collections exist to allow the user to
-            have multiple repositories of
-            <filename>.bb</filename> files that contain the same
-            exact package.
-            For example, one could easily use them to make one's
-            own local copy of an upstream repository, but with
-            custom modifications that one does not want upstream.
-            Here is an example:
-            <literallayout class='monospaced'>
-    BBFILES = "/stuff/openembedded/*/*.bb /stuff/openembedded.modified/*/*.bb"
-    BBFILE_COLLECTIONS = "upstream local"
-    BBFILE_PATTERN_upstream = "^/stuff/openembedded/"
-    BBFILE_PATTERN_local = "^/stuff/openembedded.modified/"
-    BBFILE_PRIORITY_upstream = "5"
-    BBFILE_PRIORITY_local = "10"
-            </literallayout>
-            <note>
-                The layers mechanism is now the preferred method of collecting
-                code.
-                While the collections code remains, its main use is to set layer
-                priorities and to deal with overlap (conflicts) between layers.

-        <title>Providers</title>
-
-        <para>
-            Assuming BitBake has been instructed to execute a target
-            and that all the recipe files have been parsed, BitBake
-            starts to figure out how to build the target.
-            BitBake looks through the <filename>PROVIDES</filename> list
-            for each of the recipes.
-            A <filename>PROVIDES</filename> list is the list of names by which
-            the recipe can be known.
-            Each recipe's <filename>PROVIDES</filename> list is created
-            implicitly through the recipe's
-            <link linkend='var-PN'><filename>PN</filename></link> variable
-            and explicitly through the recipe's
-            <link linkend='var-PROVIDES'><filename>PROVIDES</filename></link>
-            variable, which is optional.
-        </para>
-
-        <para>
-            When a recipe uses <filename>PROVIDES</filename>, that recipe's
-            functionality can be found under an alternative name or names other
-            than the implicit <filename>PN</filename> name.
-            As an example, suppose a recipe named <filename>keyboard_1.0.bb</filename>
-            contained the following:
-            <literallayout class='monospaced'>
-     PROVIDES += "fullkeyboard"
-            </literallayout>
-            The <filename>PROVIDES</filename> list for this recipe becomes
-            "keyboard", which is implicit, and "fullkeyboard", which is explicit.
-            Consequently, the functionality found in
-            <filename>keyboard_1.0.bb</filename> can be found under two
-            different names.

-            The <filename>PROVIDES</filename> list is only part of the solution
-            for figuring out a target's recipes.
-            Because targets might have multiple providers, BitBake needs
-            to prioritize providers by determining provider preferences.
-        </para>
-
-        <para>
-            A common example in which a target has multiple providers
-            is "virtual/kernel", which is on the
-            <filename>PROVIDES</filename> list for each kernel recipe.
-            Each machine often selects the best kernel provider by using a
-            line similar to the following in the machine configuration file:
-            <literallayout class='monospaced'>
-     PREFERRED_PROVIDER_virtual/kernel = "linux-yocto"
-            </literallayout>
-            The default
-            <link linkend='var-PREFERRED_PROVIDER'><filename>PREFERRED_PROVIDER</filename></link>
-            is the provider with the same name as the target.
-            Bitbake iterates through each target it needs to build and
-            resolves them and their dependencies using this process.
-        </para>
-
-        <para>
-            Understanding how providers are chosen is made complicated by the fact
-            that multiple versions might exist for a given provider.
-            BitBake defaults to the highest version of a provider.
-            Version comparisons are made using the same method as Debian.
-            You can use the
-            <link linkend='var-PREFERRED_VERSION'><filename>PREFERRED_VERSION</filename></link>
-            variable to specify a particular version.
-            You can influence the order by using the
-            <link linkend='var-DEFAULT_PREFERENCE'><filename>DEFAULT_PREFERENCE</filename></link>
-            variable.
-        </para>
-
-        <para>
-            By default, files have a preference of "0".
-            Setting <filename>DEFAULT_PREFERENCE</filename> to "-1" makes the
-            recipe unlikely to be used unless it is explicitly referenced.
-            Setting <filename>DEFAULT_PREFERENCE</filename> to "1" makes it
-            likely the recipe is used.
-            <filename>PREFERRED_VERSION</filename> overrides any
-            <filename>DEFAULT_PREFERENCE</filename> setting.
-            <filename>DEFAULT_PREFERENCE</filename> is often used to mark newer
-            and more experimental recipe versions until they have undergone
-            sufficient testing to be considered stable.
-        </para>
-
-        <para>
-            When there are multiple “versions” of a given recipe,
-            BitBake defaults to selecting the most recent
-            version, unless otherwise specified.
-            If the recipe in question has a
-            <link linkend='var-DEFAULT_PREFERENCE'><filename>DEFAULT_PREFERENCE</filename></link>
-            set lower than the other recipes (default is 0), then
-            it will not be selected.
-            This allows the person or persons maintaining
-            the repository of recipe files to specify
-            their preference for the default selected version.
-            Additionally, the user can specify their preferred version.
-        </para>
-
-        <para>
-            If the first recipe is named <filename>a_1.1.bb</filename>, then the
-            <link linkend='var-PN'><filename>PN</filename></link> variable
-            will be set to “a”, and the
-            <link linkend='var-PV'><filename>PV</filename></link>
-            variable will be set to 1.1.
-        </para>
-
-        <para>
-            Thus, if a recipe named <filename>a_1.2.bb</filename> exists, BitBake
-            will choose 1.2 by default.
-            However, if you define the following variable in a
-            <filename>.conf</filename> file that BitBake parses, you
-            can change that preference:
-            <literallayout class='monospaced'>
-     PREFERRED_VERSION_a = "1.1"

-        <note>
-            <para>
-                It is common for a recipe to provide two versions -- a stable,
-                numbered (and preferred) version, and a version that is
-                automatically checked out from a source code repository that
-                is considered more "bleeding edge" but can be selected only
-                explicitly.
-            </para>
-
-            <para>
-                For example, in the OpenEmbedded codebase, there is a standard,
-                versioned recipe file for BusyBox,
-                <filename>busybox_1.22.1.bb</filename>,
-                but there is also a Git-based version,
-                <filename>busybox_git.bb</filename>, which explicitly contains the line
-                <literallayout class='monospaced'>
-    DEFAULT_PREFERENCE = "-1"
-                </literallayout>
-                to ensure that the numbered, stable version is always preferred
-                unless the developer selects otherwise.

-            Each target BitBake builds consists of multiple tasks such as

-            <filename>patch</filename>, <filename>configure</filename>,
-            and <filename>compile</filename>.
-            For best performance on multi-core systems, BitBake considers each

-            entity with its own set of dependencies.
-        </para>
-
-        <para>
-            Dependencies are defined through several variables.
-            You can find information about variables BitBake uses in
-            the <link linkend='ref-variables-glos'>Variables Glossary</link>
-            near the end of this manual.
-            At a basic level, it is sufficient to know that BitBake uses the

-            <link linkend='var-RDEPENDS'><filename>RDEPENDS</filename></link> variables when

-
-        <para>
-            Based on the generated list of providers and the dependency information,
-            BitBake can now calculate exactly what tasks it needs to run and in what
-            order it needs to run them.
-            The
-            "<link linkend='executing-tasks'>Executing Tasks</link>" section has more

-        </para>
-
-        <para>
-            The build now starts with BitBake forking off threads up to the limit set in the

-            variable.
-            BitBake continues to fork threads as long as there are tasks ready to run,
-            those tasks have all their dependencies met, and the thread threshold has not been
-            exceeded.
-        </para>

-            It is worth noting that you can greatly speed up the build time by properly setting

-        </para>
-
-        <para>
-            As each task completes, a timestamp is written to the directory specified by the
-            <link linkend='var-STAMP'><filename>STAMP</filename></link> variable.
-            On subsequent runs, BitBake looks in the build directory within
-            <filename>tmp/stamps</filename> and does not rerun
-            tasks that are already completed unless a timestamp is found to be invalid.
-            Currently, invalid timestamps are only considered on a per
-            recipe file basis.
-            So, for example, if the configure stamp has a timestamp greater than the
-            compile timestamp for a given target, then the compile task would rerun.
-            Running the compile task again, however, has no effect on other providers
-            that depend on that target.
-        </para>
-
-        <para>
-            The exact format of the stamps is partly configurable.
-            In modern versions of BitBake, a hash is appended to the
-            stamp so that if the configuration changes, the stamp becomes
-            invalid and the task is automatically rerun.
-            This hash, or signature used, is governed by the signature policy
-            that is configured (see the
-            "<link linkend='checksums'>Checksums (Signatures)</link>"
-            section for information).
-            It is also possible to append extra metadata to the stamp using
-            the <filename>[stamp-extra-info]</filename> task flag.
-            For example, OpenEmbedded uses this flag to make some tasks machine-specific.

-            Some tasks are marked as "nostamp" tasks.

-            Tasks can be either a shell task or a Python task.
-            For shell tasks, BitBake writes a shell script to

-            and then executes the script.

-            Output from the shell script goes to the file
-            <filename>${T}/log.do_taskname.pid</filename>.
-            Looking at the expanded shell functions in the run file and

-            The order in which BitBake runs the tasks is controlled by its

-        <title>Checksums (Signatures)</title>
-
-        <para>
-            A checksum is a unique signature of a task's inputs.
-            The signature of a task can be used to determine if a task
-            needs to be run.
-            Because it is a change in a task's inputs that triggers running
-            the task, BitBake needs to detect all the inputs to a given task.
-            For shell tasks, this turns out to be fairly easy because
-            BitBake generates a "run" shell script for each task and
-            it is possible to create a checksum that gives you a good idea of when
-            the task's data changes.
-        </para>
-
-        <para>
-            To complicate the problem, some things should not be included in
-            the checksum.
-            First, there is the actual specific build path of a given task -
-            the working directory.
-            It does not matter if the working directory changes because it should not
-            affect the output for target packages.
-            The simplistic approach for excluding the working directory is to set
-            it to some fixed value and create the checksum for the "run" script.
-            BitBake goes one step better and uses the
-            <link linkend='var-BB_HASHBASE_WHITELIST'><filename>BB_HASHBASE_WHITELIST</filename></link>
-            variable to define a list of variables that should never be included
-            when generating the signatures.
-        </para>
-
-        <para>
-            Another problem results from the "run" scripts containing functions that
-            might or might not get called.
-            The incremental build solution contains code that figures out dependencies
-            between shell functions.
-            This code is used to prune the "run" scripts down to the minimum set,
-            thereby alleviating this problem and making the "run" scripts much more
-            readable as a bonus.
-        </para>
-
-        <para>
-            So far we have solutions for shell scripts.
-            What about Python tasks?
-            The same approach applies even though these tasks are more difficult.
-            The process needs to figure out what variables a Python function accesses
-            and what functions it calls.
-            Again, the incremental build solution contains code that first figures out
-            the variable and function dependencies, and then creates a checksum for the data
-            used as the input to the task.
-        </para>
-
-        <para>
-            Like the working directory case, situations exist where dependencies
-            should be ignored.
-            For these cases, you can instruct the build process to ignore a dependency
-            by using a line like the following:
-            <literallayout class='monospaced'>
-     PACKAGE_ARCHS[vardepsexclude] = "MACHINE"
-            </literallayout>
-            This example ensures that the <filename>PACKAGE_ARCHS</filename> variable does not
-            depend on the value of <filename>MACHINE</filename>, even if it does reference it.
-        </para>
-
-        <para>
-            Equally, there are cases where we need to add dependencies BitBake
-            is not able to find.
-            You can accomplish this by using a line like the following:
-            <literallayout class='monospaced'>
-      PACKAGE_ARCHS[vardeps] = "MACHINE"
-            </literallayout>
-            This example explicitly adds the <filename>MACHINE</filename> variable as a
-            dependency for <filename>PACKAGE_ARCHS</filename>.
-        </para>
-
-        <para>
-            Consider a case with in-line Python, for example, where BitBake is not
-            able to figure out dependencies.
-            When running in debug mode (i.e. using <filename>-DDD</filename>), BitBake
-            produces output when it discovers something for which it cannot figure out
-            dependencies.
-        </para>
-
-        <para>
-            Thus far, this section has limited discussion to the direct inputs into a task.
-            Information based on direct inputs is referred to as the "basehash" in the
-            code.
-            However, there is still the question of a task's indirect inputs - the
-            things that were already built and present in the build directory.
-            The checksum (or signature) for a particular task needs to add the hashes
-            of all the tasks on which the particular task depends.
-            Choosing which dependencies to add is a policy decision.
-            However, the effect is to generate a master checksum that combines the basehash
-            and the hashes of the task's dependencies.
-        </para>
-
-        <para>
-            At the code level, there are a variety of ways both the basehash and the
-            dependent task hashes can be influenced.
-            Within the BitBake configuration file, we can give BitBake some extra information
-            to help it construct the basehash.
-            The following statement effectively results in a list of global variable
-            dependency excludes - variables never included in any checksum.
-            This example uses variables from OpenEmbedded to help illustrate
-            the concept:
-            <literallayout class='monospaced'>
-     BB_HASHBASE_WHITELIST ?= "TMPDIR FILE PATH PWD BB_TASKHASH BBPATH DL_DIR \
-         SSTATE_DIR THISDIR FILESEXTRAPATHS FILE_DIRNAME HOME LOGNAME SHELL TERM \
-         USER FILESPATH STAGING_DIR_HOST STAGING_DIR_TARGET COREBASE PRSERV_HOST \
-         PRSERV_DUMPDIR PRSERV_DUMPFILE PRSERV_LOCKDOWN PARALLEL_MAKE \
-         CCACHE_DIR EXTERNAL_TOOLCHAIN CCACHE CCACHE_DISABLE LICENSE_PATH SDKPKGSUFFIX"
-            </literallayout>
-            The previous example excludes the work directory, which is part of
-            <filename>TMPDIR</filename>.
-        </para>
-
-        <para>
-            The rules for deciding which hashes of dependent tasks to include through
-            dependency chains are more complex and are generally accomplished with a
-            Python function.
-            The code in <filename>meta/lib/oe/sstatesig.py</filename> shows two examples
-            of this and also illustrates how you can insert your own policy into the system
-            if so desired.
-            This file defines the two basic signature generators OpenEmbedded Core
-            uses:  "OEBasic" and "OEBasicHash".
-            By default, there is a dummy "noop" signature handler enabled in BitBake.
-            This means that behavior is unchanged from previous versions.
-            <filename>OE-Core</filename> uses the "OEBasicHash" signature handler by default
-            through this setting in the <filename>bitbake.conf</filename> file:
-            <literallayout class='monospaced'>
-     BB_SIGNATURE_HANDLER ?= "OEBasicHash"
-            </literallayout>
-            The "OEBasicHash" <filename>BB_SIGNATURE_HANDLER</filename> is the same as the
-            "OEBasic" version but adds the task hash to the stamp files.
-            This results in any metadata change that changes the task hash, automatically
-            causing the task to be run again.
-            This removes the need to bump
-            <link linkend='var-PR'><filename>PR</filename></link>
-            values, and changes to metadata automatically ripple across the build.
-        </para>
-
-        <para>
-            It is also worth noting that the end result of these signature generators is to
-            make some dependency and hash information available to the build.
-            This information includes:
-            <itemizedlist>
-                <listitem><para><filename>BB_BASEHASH_task-</filename><replaceable>taskname</replaceable>:
-                    The base hashes for each task in the recipe.

-        </para>
-
-        <para>
-            It is worth noting that BitBake's "-S" option lets you
-            debug Bitbake's processing of signatures.
-            The options passed to -S allow different debugging modes
-            to be used, either using BitBake's own debug functions
-            or possibly those defined in the metadata/signature handler
-            itself.
-            The simplest parameter to pass is "none", which causes a
-            set of signature information to be written out into
-            <filename>STAMPS_DIR</filename>
-            corresponding to the targets specified.
-            The other currently available parameter is "printdiff",
-            which causes BitBake to try to establish the closest
-            signature match it can (e.g. in the sstate cache) and then
-            run <filename>bitbake-diffsigs</filename> over the matches
-            to determine the stamps and delta where these two
-            stamp trees diverge.
-            <note>
-                It is likely that future versions of BitBake will
-                provide other signature handlers triggered through
-                additional "-S" parameters.

-
-        <para>
-            The setscene process enables BitBake to handle "pre-built" artifacts.
-            The ability to handle and reuse these artifacts allows BitBake
-            the luxury of not having to build something from scratch every time.
-            Instead, BitBake can use, when possible, existing build artifacts.
-        </para>
-
-        <para>
-            BitBake needs to have reliable data indicating whether or not an
-            artifact is compatible.
-            Signatures, described in the previous section, provide an ideal
-            way of representing whether an artifact is compatible.
-            If a signature is the same, an object can be reused.
-        </para>
-
-        <para>
-            If an object can be reused, the problem then becomes how to
-            replace a given task or set of tasks with the pre-built artifact.
-            BitBake solves the problem with the "setscene" process.
-        </para>
-
-        <para>
-            When BitBake is asked to build a given target, before building anything,
-            it first asks whether cached information is available for any of the
-            targets it's building, or any of the intermediate targets.
-            If cached information is available, BitBake uses this information instead of
-            running the main tasks.
-        </para>
-
-        <para>
-            BitBake first calls the function defined by the
-            <link linkend='var-BB_HASHCHECK_FUNCTION'><filename>BB_HASHCHECK_FUNCTION</filename></link>
-            variable with a list of tasks and corresponding
-            hashes it wants to build.
-            This function is designed to be fast and returns a list
-            of the tasks for which it believes in can obtain artifacts.
-        </para>
-
-        <para>
-            Next, for each of the tasks that were returned as possibilities,
-            BitBake executes a setscene version of the task that the possible
-            artifact covers.
-            Setscene versions of a task have the string "_setscene" appended to the
-            task name.
-            So, for example, the task with the name <filename>xxx</filename> has
-            a setscene task named <filename>xxx_setscene</filename>.
-            The setscene version of the task executes and provides the necessary
-            artifacts returning either success or failure.
-        </para>
-
-        <para>
-            As previously mentioned, an artifact can cover more than one task.
-            For example, it is pointless to obtain a compiler if you
-            already have the compiled binary.
-            To handle this, BitBake calls the
-            <link linkend='var-BB_SETSCENE_DEPVALID'><filename>BB_SETSCENE_DEPVALID</filename></link>
-            function for each successful setscene task to know whether or not it needs
-            to obtain the dependencies of that task.
-        </para>
-
-        <para>
-            Finally, after all the setscene tasks have executed, BitBake calls the
-            function listed in
-            <link linkend='var-BB_SETSCENE_VERIFY_FUNCTION2'><filename>BB_SETSCENE_VERIFY_FUNCTION2</filename></link>
-            with the list of tasks BitBake thinks has been "covered".
-            The metadata can then ensure that this list is correct and can
-            inform BitBake that it wants specific tasks to be run regardless
-            of the setscene result.
-        </para>

-    <para>
-        BitBake's fetch module is a standalone piece of library code
-        that deals with the intricacies of downloading source code
-        and files from remote systems.
-        Fetching source code is one of the cornerstones of building software.
-        As such, this module forms an important part of BitBake.
-    </para>
-
-    <para>
-        The current fetch module is called "fetch2" and refers to the
-        fact that it is the second major version of the API.
-        The original version is obsolete and has been removed from the codebase.
-        Thus, in all cases, "fetch" refers to "fetch2" in this
-        manual.
-    </para>

-        <title>The Download (Fetch)</title>
-
-        <para>
-            BitBake takes several steps when fetching source code or files.
-            The fetcher codebase deals with two distinct processes in order:
-            obtaining the files from somewhere (cached or otherwise)
-            and then unpacking those files into a specific location and
-            perhaps in a specific way.
-            Getting and unpacking the files is often optionally followed
-            by patching.
-            Patching, however, is not covered by this module.
-        </para>
-
-        <para>
-            The code to execute the first part of this process, a fetch,
-            looks something like the following:
-            <literallayout class='monospaced'>
-     src_uri = (d.getVar('SRC_URI') or "").split()
-     fetcher = bb.fetch2.Fetch(src_uri, d)
-     fetcher.download()
-            </literallayout>
-            This code sets up an instance of the fetch class.
-            The instance uses a space-separated list of URLs from the
-            <link linkend='var-SRC_URI'><filename>SRC_URI</filename></link>
-            variable and then calls the <filename>download</filename>
-            method to download the files.
-        </para>
-
-        <para>
-            The instantiation of the fetch class is usually followed by:
-            <literallayout class='monospaced'>
-     rootdir = l.getVar('WORKDIR')
-     fetcher.unpack(rootdir)
-            </literallayout>
-            This code unpacks the downloaded files to the
-            specified by <filename>WORKDIR</filename>.
-            <note>
-                For convenience, the naming in these examples matches
-                the variables used by OpenEmbedded.
-                If you want to see the above code in action, examine
-                the OpenEmbedded class file <filename>base.bbclass</filename>.
-            </note>
-            The <filename>SRC_URI</filename> and <filename>WORKDIR</filename>
-            variables are not hardcoded into the fetcher, since those fetcher
-            methods can be (and are) called with different variable names.
-            In OpenEmbedded for example, the shared state (sstate) code uses
-            the fetch module to fetch the sstate files.
-        </para>
-
-        <para>
-            When the <filename>download()</filename> method is called,
-            BitBake tries to resolve the URLs by looking for source files
-            in a specific search order:
-            <itemizedlist>
-                <listitem><para><emphasis>Pre-mirror Sites:</emphasis>
-                    BitBake first uses pre-mirrors to try and find source files.
-                    These locations are defined using the
-                    <link linkend='var-PREMIRRORS'><filename>PREMIRRORS</filename></link>
-                    variable.
-                    </para></listitem>
-                <listitem><para><emphasis>Source URI:</emphasis>
-                    If pre-mirrors fail, BitBake uses the original URL (e.g from
-                    <filename>SRC_URI</filename>).
-                    </para></listitem>
-                <listitem><para><emphasis>Mirror Sites:</emphasis>
-                    If fetch failures occur, BitBake next uses mirror locations as
-                    defined by the
-                    <link linkend='var-MIRRORS'><filename>MIRRORS</filename></link>
-                    variable.
-                    </para></listitem>
-            </itemizedlist>
-        </para>
-
-        <para>
-            For each URL passed to the fetcher, the fetcher
-            calls the submodule that handles that particular URL type.
-            This behavior can be the source of some confusion when you
-            are providing URLs for the <filename>SRC_URI</filename>
-            variable.
-            Consider the following two URLs:
-            <literallayout class='monospaced'>
-     http://git.yoctoproject.org/git/poky;protocol=git
-     git://git.yoctoproject.org/git/poky;protocol=http
-            </literallayout>
-            In the former case, the URL is passed to the
-            <filename>wget</filename> fetcher, which does not
-            understand "git".
-            Therefore, the latter case is the correct form since the

-            It is useful to note that BitBake supports
-            cross-URLs.
-            It is possible to mirror a Git repository on an HTTP
-            server as a tarball.
-            This is what the <filename>git://</filename> mapping in

-            Since network accesses are slow, Bitbake maintains a
-            cache of files downloaded from the network.
-            Any source files that are not local (i.e.
-            downloaded from the Internet) are placed into the download
-            directory, which is specified by the

-            File integrity is of key importance for reproducing builds.
-            For non-local archive downloads, the fetcher code can verify
-            SHA-256 and MD5 checksums to ensure the archives have been
-            downloaded correctly.
-            You can specify these checksums by using the
-            <filename>SRC_URI</filename> variable with the appropriate
-            varflags as follows:
-            <literallayout class='monospaced'>
-     SRC_URI[md5sum] = "<replaceable>value</replaceable>"
-     SRC_URI[sha256sum] = "<replaceable>value</replaceable>"
-            </literallayout>
-            You can also specify the checksums as parameters on the
-            <filename>SRC_URI</filename> as shown below:
-            <literallayout class='monospaced'>
-     SRC_URI = "http://example.com/foobar.tar.bz2;md5sum=4a8e0f237e961fd7785d19d07fdb994d"
-            </literallayout>
-            If multiple URIs exist, you can specify the checksums either
-            directly as in the previous example, or you can name the URLs.
-            The following syntax shows how you name the URIs:
-            <literallayout class='monospaced'>
-     SRC_URI = "http://example.com/foobar.tar.bz2;name=foo"
-     SRC_URI[foo.md5sum] = 4a8e0f237e961fd7785d19d07fdb994d
-            </literallayout>
-            After a file has been downloaded and has had its checksum checked,
-            a ".done" stamp is placed in <filename>DL_DIR</filename>.
-            BitBake uses this stamp during subsequent builds to avoid
-            downloading or comparing a checksum for the file again.
-            <note>
-                It is assumed that local storage is safe from data corruption.
-                If this were not the case, there would be bigger issues to worry about.

-            A number of parameters exist that you can specify within the

-                    are unpacked.
-                    If set to "0", the unpack stage leaves the file alone.
-                    This parameter is useful when you want an archive to be

-            As mentioned, the Git fetcher has its own unpack method that

-            Basically, this method works by cloning the tree into the final
-            directory.

-                <filename>file://</filename>.
-                The filename you specify within the URL can be
-                either an absolute or relative path to a file.
-                If the filename is relative, the contents of the

-                This fetcher obtains files from web and FTP servers.

-                The executable and parameters used are specified by the

-                to sensible values.
-                The fetcher supports a parameter "downloadfilename" that
-                allows the name of the downloaded file to be specified.
-                Specifying the name of the downloaded file is useful

-                <link linkend='var-DL_DIR'><filename>DL_DIR</filename></link>
-                when dealing with multiple files that have the same name.

-            </para>
-            <note>
-               Because URL parameters are delimited by semi-colons, this can
-               introduce ambiguity when parsing URLs that also contain semi-colons,
-               for example:
-                <literallayout class='monospaced'>
-     SRC_URI = "http://abc123.org/git/?p=gcc/gcc.git;a=snapshot;h=a5dd47"
-                </literallayout>
-               Such URLs should should be modified by replacing semi-colons with '&amp;' characters:
-               <literallayout class='monospaced'>
-     SRC_URI = "http://abc123.org/git/?p=gcc/gcc.git&amp;a=snapshot&amp;h=a5dd47"
-                </literallayout>
-                In most cases this should work. Treating semi-colons and '&amp;' in queries
-                identically is recommended by the World Wide Web Consortium (W3C).
-                Note that due to the nature of the URL, you may have to specify the name
-                of the downloaded file as well:
-              <literallayout class='monospaced'>

-                This fetcher submodule fetches code from the Git
-                source control system.
-                The fetcher works by creating a bare clone of the
-                remote into
-                <link linkend='var-GITDIR'><filename>GITDIR</filename></link>,
-                which is usually <filename>DL_DIR/git2</filename>.
-                This bare clone is then cloned into the work directory during the
-                unpack stage when a specific tree is checked out.
-                This is done using alternates and by reference to
-                minimize the amount of duplicate data on the disk and
-                make the unpack process fast.
-                The executable used can be set with

-                        The protocol used to fetch the files.

-                        If a hostname is not set, the Git protocol is "file".
-                        You can also use "http", "https", "ssh" and "rsync".

-                        You should set this parameter to "1" if
-                        revisions can become detached from branches.
-                        In this case, the source mirror tarball is done per

-                        Rebasing the upstream Git repository could cause the
-                        current revision to disappear from the upstream repository.
-                        This option reminds the fetcher to preserve the local cache
-                        carefully for future use.

-                        Specifies a tag to use for the checkout.
-                        To correctly resolve tags, BitBake must access the

-                        For that reason, tags are often not used.
-                        As far as Git is concerned, the "tag" parameter behaves
-                        effectively the same as the "rev" parameter.

-
-        <para>
-            First, you need to be sure that you can run BitBake.
-            Set your working directory to where your local BitBake
-            files are and run the following command:
-            <literallayout class='monospaced'>
-     $ ./bin/bitbake --version
-     BitBake Build Tool Core version 1.23.0, bitbake version 1.23.0
-            </literallayout>
-            The console output tells you what version you are running.
-        </para>
-
-        <para>
-            The recommended method to run BitBake is from a directory of your
-            choice.
-            To be able to run BitBake from any directory, you need to add the
-            executable binary to your binary to your shell's environment
-            <filename>PATH</filename> variable.
-            First, look at your current <filename>PATH</filename> variable
-            by entering the following:
-            <literallayout class='monospaced'>
-     $ echo $PATH
-            </literallayout>
-            Next, add the directory location for the BitBake binary to the
-            <filename>PATH</filename>.
-            Here is an example that adds the
-            <filename>/home/scott-lenovo/bitbake/bin</filename> directory
-            to the front of the <filename>PATH</filename> variable:
-            <literallayout class='monospaced'>
-     $ export PATH=/home/scott-lenovo/bitbake/bin:$PATH
-            </literallayout>
-            You should now be able to enter the <filename>bitbake</filename>
-            command from the command line while working from any directory.

-            The overall goal of this exercise is to build a
-            complete "Hello World" example utilizing task and layer
-            concepts.
-            Because this is how modern projects such as OpenEmbedded and
-            the Yocto Project utilize BitBake, the example
-            provides an excellent starting point for understanding
-            BitBake.

-        <para>
-            To help you understand how to use BitBake to build targets,
-            the example starts with nothing but the <filename>bitbake</filename>
-            command, which causes BitBake to fail and report problems.
-            The example progresses by adding pieces to the build to
-            eventually conclude with a working, minimal "Hello World"
-            example.

-            As stated earlier, the goal of this example
-            is to eventually compile "Hello World".
-            However, it is unknown what BitBake needs and what you have
-            to provide in order to achieve that goal.
-            Recall that BitBake utilizes three types of metadata files:
-            <link linkend='configuration-files'>Configuration Files</link>,
-            <link linkend='classes'>Classes</link>, and
-            <link linkend='recipes'>Recipes</link>.
-            But where do they go?
-            How does BitBake find them?
-            BitBake's error messaging helps you answer these types of questions
-            and helps you better understand exactly what is going on.

-            <listitem><para><emphasis>Create a Project Directory:</emphasis>
-                First, set up a directory for the "Hello World" project.
-                Here is how you can do so in your home directory:
-                <literallayout class='monospaced'>
-     $ mkdir ~/hello
-     $ cd ~/hello
-                </literallayout>
-                This is the directory that BitBake will use to do all of
-                its work.
-                You can use this directory to keep all the metafiles needed
-                by BitBake.
-                Having a project directory is a good way to isolate your
-                project.

-            <listitem><para><emphasis>Run Bitbake:</emphasis>
-                At this point, you have nothing but a project directory.
-                Run the <filename>bitbake</filename> command and see what
-                it does:
-                <literallayout class='monospaced'>
-     $ bitbake
-     The BBPATH variable is not set and bitbake did not
-     find a conf/bblayers.conf file in the expected location.

-        Welcome to the BitBake User Manual.
-        This manual provides information on the BitBake tool.
-        The information attempts to be as independent as possible regarding
-        systems that use BitBake, such as OpenEmbedded and the
-        Yocto Project.
-        In some cases, scenarios or examples within the context of
-        a build system are used in the manual to help with understanding.
-        For these cases, the manual clearly states the context.

-            Fundamentally, BitBake is a generic task execution
-            engine that allows shell and Python tasks to be run
-            efficiently and in parallel while working within
-            complex inter-task dependency constraints.

-
-        <para>
-            BitBake was originally a part of the OpenEmbedded project.
-            It was inspired by the Portage package management system
-            used by the Gentoo Linux distribution.
-            On December 7, 2004, OpenEmbedded project team member
-            Chris Larson split the project into two distinct pieces:
-            <itemizedlist>
-                <listitem><para>BitBake, a generic task executor</para></listitem>
-                <listitem><para>OpenEmbedded, a metadata set utilized by
-                    BitBake</para></listitem>
-            </itemizedlist>
-            Today, BitBake is the primary basis of the
-            <ulink url="http://www.openembedded.org/">OpenEmbedded</ulink>
-            project, which is being used to build and maintain Linux
-            distributions such as the
-            <ulink url='http://www.angstrom-distribution.org/'>Angstrom Distribution</ulink>,
-            and which is also being used as the build tool for Linux projects
-            such as the
-            <ulink url='http://www.yoctoproject.org'>Yocto Project</ulink>.
-        </para>
-
-        <para>
-            Prior to BitBake, no other build tool adequately met the needs of
-            an aspiring embedded Linux distribution.
-            All of the build systems used by traditional desktop Linux
-            distributions lacked important functionality, and none of the
-            ad hoc Buildroot-based systems, prevalent in the
-            embedded space, were scalable or maintainable.

-        <para>
-            BitBake is a program written in the Python language.
-            At the highest level, BitBake interprets metadata, decides
-            what tasks are required to run, and executes those tasks.
-            Similar to GNU Make, BitBake controls how software is
-            built.
-            GNU Make achieves its control through "makefiles", while
-            BitBake uses "recipes".

-
-        <para>
-            BitBake extends the capabilities of a simple
-            tool like GNU Make by allowing for the definition of much more
-            complex tasks, such as assembling entire embedded Linux
-            distributions.

-                Within the context of BitBake, or any project utilizing BitBake
-                as its build system, files with the <filename>.bb</filename>
-                extension are referred to as recipes.
-                <note>
-                    The term "package" is also commonly used to describe recipes.
-                    However, since the same word is used to describe packaged
-                    output from a project, it is best to maintain a single
-                    descriptive term - "recipes".
-                    Put another way, a single "recipe" file is quite capable
-                    of generating a number of related but separately installable
-                    "packages".
-                    In fact, that ability is fairly common.

-            <para>
-                Layers allow you to isolate different types of
-                customizations from each other.
-                While you might find it tempting to keep everything in one layer
-                when working on a single project, the more modular you organize
-                your metadata, the easier it is to cope with future changes.
-            </para>
-
-            <para>
-                To illustrate how you can use layers to keep things modular,
-                consider customizations you might make to support a specific target machine.
-                These types of customizations typically reside in a special layer,
-                rather than a general layer, called a Board Support Package (BSP)
-                Layer.
-                Furthermore, the machine customizations should be isolated from
-                recipes and metadata that support a new GUI environment, for
-                example.
-                This situation gives you a couple of layers: one for the machine
-                configurations and one for the GUI environment.
-                It is important to understand, however, that the BSP layer can still
-                make machine-specific additions to recipes within
-                the GUI environment layer without polluting the GUI layer itself
-                with those machine-specific changes.
-                You can accomplish this through a recipe that is a BitBake append
-                (<filename>.bbappend</filename>) file.

-                Append files, which are files that have the

-            </para>
-
-            <para>
-                BitBake expects every append file to have a corresponding recipe file.
-                Furthermore, the append file and corresponding recipe file
-                must use the same root filename.
-                The filenames can differ only in the file type suffix used
-                (e.g. <filename>formfactor_0.0.bb</filename> and
-                <filename>formfactor_0.0.bbappend</filename>).
-            </para>
-
-            <para>
-                Information in append files extends or

-            </para>
-
-            <para>
-                When you name an append file, you can use the
-                wildcard character (%) to allow for matching recipe names.
-                For example, suppose you have an append file named
-                as follows:
-                <literallayout class='monospaced'>
-     busybox_1.21.%.bbappend
-                </literallayout>
-                That append file would match any <filename>busybox_1.21.x.bb</filename>
-                version of the recipe.
-                So, the append file would match the following recipe names:
-                <literallayout class='monospaced'>
-     busybox_1.21.1.bb
-     busybox_1.21.2.bb
-     busybox_1.21.3.bb
-                </literallayout>
-                If the <filename>busybox</filename> recipe was updated to
-                <filename>busybox_1.3.0.bb</filename>, the append name would not
-                match.
-                However, if you named the append file
-                <filename>busybox_1.%.bbappend</filename>, then you would have a match.
-            </para>
-
-            <para>
-                In the most general case, you could name the append file something as
-                simple as <filename>busybox_%.bbappend</filename> to be entirely

-                <listitem><para><emphasis>Cloning BitBake:</emphasis>
-                    Using Git to clone the BitBake source code repository
-                    is the recommended method for obtaining BitBake.
-                    Cloning the repository makes it easy to get bug fixes
-                    and have access to stable branches and the master
-                    branch.
-                    Once you have cloned BitBake, you should use
-                    the latest stable
-                    branch for development since the master branch is for
-                    BitBake development and might contain less stable changes.
-                    </para>
-                    <para>You usually need a version of BitBake
-                    that matches the metadata you are using.

-                    </literallayout>
-                    This command clones the BitBake Git repository into a
-                    directory called <filename>bitbake</filename>.
-                    Alternatively, you can
-                    designate a directory after the
-                    <filename>git clone</filename> command
-                    if you want to call the new directory something
-                    other than <filename>bitbake</filename>.

-                    Executing tasks for a single recipe file is relatively simple.
-                    You specify the file in question, and BitBake parses
-                    it and executes the specified task.
-                    If you do not specify a task, BitBake executes the default
-                    task, which is "build”.
-                    BitBake obeys inter-task dependencies when doing

-
-                <para>
-                    BitBake is able to generate dependency graphs using
-                    the <filename>dot</filename> syntax.
-                    You can convert these graphs into images using the
-                    <filename>dot</filename> tool from
-                    <ulink url='http://www.graphviz.org'>Graphviz</ulink>.
-                </para>
-
-                <para>
-                    When you generate a dependency graph, BitBake writes three files
-                    to the current working directory:
-                    <itemizedlist>
-                        <listitem><para>
-                            <emphasis><filename>recipe-depends.dot</filename>:</emphasis>
-                            Shows dependencies between recipes (i.e. a collapsed version of
-                            <filename>task-depends.dot</filename>).
-                            </para></listitem>
-                        <listitem><para>

-                            Shows dependencies between tasks.
-                            These dependencies match BitBake's internal task execution list.
-                            </para></listitem>
-                        <listitem><para>
-                            <emphasis><filename>pn-buildlist</filename>:</emphasis>
-                            Shows a simple list of targets that are to be built.
-                            </para></listitem>
-                    </itemizedlist>
-                </para>
-
-                <para>
-                    To stop depending on common depends, use the "-I" depend
-                    option and BitBake omits them from the graph.
-                    Leaving this information out can produce more readable graphs.
-                    This way, you can remove from the graph
-                    <filename>DEPENDS</filename> from inherited classes
-                    such as <filename>base.bbclass</filename>.
-                </para>
-
-                <para>
-                    Here are two examples that create dependency graphs.
-                    The second example omits depends common in OpenEmbedded from
-                    the graph:
-                    <literallayout class='monospaced'>
-     $ bitbake -g foo
-
-     $ bitbake -g -I virtual/kernel -I eglibc foo
-                    </literallayout>

-   Structure
-   ---------
-
-   The stylesheet is divided into the following sections:
-
-       Positioning
-          Margins, paddings, width, font-size, clearing.
-       Decorations
-          Borders, style
-       Colors
-          Colors
-       Graphics
-          Graphical backgrounds
-       Nasty IE tweaks
-          Workarounds needed to make it work in internet explorer,
-          currently makes the stylesheet non validating, but up until
-          this point it is validating.
-       Mozilla extensions

+        <title>Introduction</title>
+        <section>
+            <title>Overview</title>
+            <para>BitBake is, at its simplest, a tool for executing
+tasks and managing metadata.  As such, its similarities to GNU make and other
+build tools are readily apparent.  It was inspired by Portage, the package management system used by the Gentoo Linux distribution.  BitBake is the basis of the <ulink url="http://www.openembedded.org/">OpenEmbedded</ulink> project, which is being used to build and maintain a number of embedded Linux distributions/projects such as Angstrom and the Yocto project.</para>
+        </section>
+        <section>
+            <title>Background and goals</title>
+            <para>Prior to BitBake, no other build tool adequately met
+the needs of an aspiring embedded Linux distribution.  All of the
+buildsystems used by traditional desktop Linux distributions lacked
+important functionality, and none of the ad-hoc
+<emphasis>buildroot</emphasis> systems, prevalent in the
+embedded space, were scalable or maintainable.</para>
+
+      <para>Some important original goals for BitBake were:
+            <itemizedlist>
+                <listitem><para>Handle crosscompilation.</para></listitem>
+                <listitem><para>Handle interpackage dependencies (build time on target architecture, build time on native architecture, and runtime).</para></listitem>
+                <listitem><para>Support running any number of tasks within a given package, including, but not limited to, fetching upstream sources, unpacking them, patching them, configuring them, et cetera.</para></listitem>
+                <listitem><para>Must be Linux distribution agnostic (both build and target).</para></listitem>
+                <listitem><para>Must be architecture agnostic</para></listitem>
+                <listitem><para>Must support multiple build and target operating systems (including Cygwin, the BSDs, etc).</para></listitem>
+                <listitem><para>Must be able to be self contained, rather than tightly integrated into the build machine's root filesystem.</para></listitem>
+                <listitem><para>There must be a way to handle conditional metadata (on target architecture, operating system, distribution, machine).</para></listitem>
+                <listitem><para>It must be easy for the person using the tools to supply their own local metadata and packages to operate against.</para></listitem>
+                <listitem><para>Must make it easy to collaborate
+between multiple projects using BitBake for their
+builds.</para></listitem>
+		<listitem><para>Should provide an inheritance mechanism to
+share common metadata between many packages.</para></listitem>
+            </itemizedlist>
+        </para>
+        <para>Over time it has become apparent that some further requirements were necessary:
+            <itemizedlist>
+                <listitem><para>Handle variants of a base recipe (native, sdk, multilib).</para></listitem>
+                <listitem><para>Able to split metadata into layers and allow layers to override each other.</para></listitem>
+                <listitem><para>Allow representation of a given set of input variables to a task as a checksum.</para></listitem>
+                <listitem><para>based on that checksum, allow acceleration of builds with prebuilt components.</para></listitem>
+            </itemizedlist>
+        </para>
+
+        <para>BitBake satisfies all the original requirements and many more with extensions being made to the basic functionality to reflect the additionl requirements.  Flexibility and power have always been the priorities.  It is highly extensible, supporting embedded Python code and execution of any arbitrary tasks.</para>

+        <title>Metadata</title>
+        <section>
+            <title>Description</title>
+            <itemizedlist>
+                <para>BitBake metadata can be classified into 3 major areas:</para>
+                <listitem>
+                    <para>Configuration Files</para>
+                </listitem>
+                <listitem>
+                    <para>.bb Files</para>
+                </listitem>
+                <listitem>
+                    <para>Classes</para>
+                </listitem>
+            </itemizedlist>
+            <para>What follows are a large number of examples of BitBake metadata.  Any syntax which isn't supported in any of the aforementioned areas will be documented as such.</para>
+            <section>
+                <title>Basic variable setting</title>
+                <para><screen><varname>VARIABLE</varname> = "value"</screen></para>

+                <para>BitBake supports variables referencing one another's contents using a syntax which is similar to shell scripting</para>

+<varname>B</varname> = "pre${A}post"</screen></para>
+                <para>This results in <varname>A</varname> containing <literal>aval</literal> and <varname>B</varname> containing <literal>preavalpost</literal>.</para>
+            </section>
+            <section>

+                <para><screen><varname>A</varname> ?= "aval"</screen></para>
+                <para>If <varname>A</varname> is set before the above is called, it will retain its previous value. If <varname>A</varname> is unset prior to the above call, <varname>A</varname> will be set to <literal>aval</literal>.  Note that this assignment is immediate, so if there are multiple ?= assignments to a single variable, the first of those will be used.</para>
+            </section>
+            <section>
+                <title>Setting a weak default value (??=)</title>
+                <para><screen><varname>A</varname> ??= "somevalue"
+<varname>A</varname> ??= "someothervalue"</screen></para>
+                <para>If <varname>A</varname> is set before the above, it will retain that value.  If <varname>A</varname> is unset prior to the above, <varname>A</varname> will be set to <literal>someothervalue</literal>.  This is a lazy/weak assignment in that the assignment does not occur until the end of the parsing process, so that the last, rather than the first, ??= assignment to a given variable will be used. Any other setting of A using = or ?= will however override the value set with ??=</para>

+            <section>
+                <title>Immediate variable expansion (:=)</title>
+                <para>:= results in a variable's contents being expanded immediately, rather than when the variable is actually used.</para>

So, if you have a variable which is conditional on <quote>arm</quote>, and <quote>arm</quote> is in OVERRIDES, then the <quote>arm</quote> specific version of the variable is used rather than the non-conditional version.  Example:</para>

As an example, setting <screen>BBCLASSEXTEND = "native"</screen> results in a second incarnation of the current recipe being available.  This second incarantion will have the "native" class inherited.</para>
+                <para>The second feature is <varname>BBVERSIONS</varname>.  This variable allows a single recipe to build multiple versions of a project from a single recipe file, and allows you to specify conditional metadata (using the <varname>OVERRIDES</varname> mechanism) for a single version, or an optionally named range of versions:</para>
+                <para><screen>BBVERSIONS = "1.0 2.0 git"
+SRC_URI_git = "git://someurl/somepath.git"</screen></para>

+SRC_URI_append_1.0.7+ = "file://some_patch_which_the_new_versions_need.patch;patch=1"</screen></para>
+                <para>Note that the name of the range will default to the original version of the recipe, so given OE, a recipe file of foo_1.0.0+.bb will default the name of its versions to 1.0.0+.  This is useful, as the range name is not only placed into overrides; it's also made available for the metadata to use in the form of the <varname>BPV</varname> variable, for use in file:// search paths (<varname>FILESPATH</varname>).</para>

+
+            <para>The SRC_URI is normally used to tell BitBake which files to fetch. The next sections will describe the available fetchers and their options. Each fetcher honors a set of variables and per URI parameters separated by a <quote>;</quote> consisting of a key and a value. The semantics of the variables and parameters are defined by the fetcher. BitBake tries to have consistent semantics between the different fetchers.
+            </para>
+
+            <para>The overall fetch process is that first, fetches are attempted from PREMIRRORS. If those don't work, the original SRC_URI is attempted and if that fails, BitBake will fall back to MIRRORS. Cross urls are supported, so its possible to mirror a git repository on an http server as a tarball for example. Some example commonly used mirror definitions are:</para>

+                <title>Introduction</title>
+                <para>bitbake is the primary command in the system.  It facilitates executing tasks in a single .bb file, or executing a given task on a set of multiple .bb files, accounting for interdependencies amongst them.</para>

+                <title>Usage and syntax</title>
+                <para>
+                    <screen><prompt>$ </prompt>bitbake --help
+usage: bitbake [options] [package ...]
+
+Executes the specified task (default is 'build') for a given set of BitBake files.
+It expects that BBFILES is defined, which is a space separated list of files to
+be executed.  BBFILES does support wildcards.
+Default BBFILES are the .bb files in the current directory.
+
+options:
+  --version             show program's version number and exit
+  -h, --help            show this help message and exit
+  -b BUILDFILE, --buildfile=BUILDFILE
+                        execute the task against this .bb file, rather than a
+                        package from BBFILES.
+  -k, --continue        continue as much as possible after an error. While the
+                        target that failed, and those that depend on it,
+                        cannot be remade, the other dependencies of these
+                        targets can be processed all the same.
+  -f, --force           force run of specified cmd, regardless of stamp status
+  -i, --interactive     drop into the interactive mode also called the BitBake
+                        shell.
+  -c CMD, --cmd=CMD     Specify task to execute. Note that this only executes
+                        the specified task for the providee and the packages
+                        it depends on, i.e. 'compile' does not implicitly call
+                        stage for the dependencies (IOW: use only if you know
+                        what you are doing). Depending on the base.bbclass a
+                        listtasks task is defined and will show available
+                        tasks
+  -r FILE, --read=FILE  read the specified file before bitbake.conf
+  -v, --verbose         output more chit-chat to the terminal
+  -D, --debug           Increase the debug level. You can specify this more
+                        than once.
+  -n, --dry-run         don't execute, just go through the motions
+  -p, --parse-only      quit after parsing the BB files (developers only)
+  -s, --show-versions   show current and preferred versions of all packages
+  -e, --environment     show the global or per-package environment (this is
+                        what used to be bbread)
+  -g, --graphviz        emit the dependency trees of the specified packages in
+                        the dot syntax
+  -I IGNORED_DOT_DEPS, --ignore-deps=IGNORED_DOT_DEPS
+                        Stop processing at the given list of dependencies when
+                        generating dependency graphs. This can help to make
+                        the graph more appealing
+  -l DEBUG_DOMAINS, --log-domains=DEBUG_DOMAINS
+                        Show debug logging for the specified logging domains
+  -P, --profile         profile the command and print a report

Clearly there needs to be a way to tell BitBake what files are available, and of those, which we want to execute at this time.  There also needs to be a way for each .bb to express its dependencies, both for build time and runtime.  There must be a way for the user to express their preferences when multiple .bb's provide the same functionality, or when there are multiple versions of a .bb.</para>

+Two files will be written into the current working directory, <emphasis>depends.dot</emphasis> containing dependency information at the package level and <emphasis>task-depends.dot</emphasis> containing a breakdown of the dependencies at the task level. To stop depending on common depends, one can use the <prompt>-I depend</prompt> to omit these from the graph. This can lead to more readable graphs.  This way, <varname>DEPENDS</varname> from inherited classes such as base.bbclass can be removed from the graph.</para>

+                <para>As you may have seen in the usage information, or in the information about .bb files, the <varname>BBFILES</varname> variable is how the BitBake tool locates its files.  This variable is a space separated list of files that are available, and supports wildcards.

If the .bb in question has a <varname>DEFAULT_PREFERENCE</varname> set lower than the other .bb's (default is 0), then it will not be selected.  This allows the person or persons maintaining the repository of .bb files to specify their preference for the default selected version.  In addition, the user can specify their preferred version.</para>

-BitBake 'Fetch' clearcase implementation
-
-The clearcase fetcher is used to retrieve files from a ClearCase repository.
-
-Usage in the recipe:
-
-    SRC_URI = "ccrc://cc.example.org/ccrc;vob=/example_vob;module=/example_module"
-    SRCREV = "EXAMPLE_CLEARCASE_TAG"
-    PV = "${@d.getVar("SRCREV", False).replace("/", "+")}"
-
-The fetcher uses the rcleartool or cleartool remote client, depending on which one is available.
-
-Supported SRC_URI options are:
-
-- vob
-    (required) The name of the clearcase VOB (with prepending "/")
-
-- module
-    The module in the selected VOB (with prepending "/")
-
-    The module and vob parameters are combined to create
-    the following load rule in the view config spec:
-                load <vob><module>
-
-- proto
-    http or https
-
-Related variables:
-
-    CCASE_CUSTOM_CONFIG_SPEC
-            Write a config spec to this variable in your recipe to use it instead
-            of the default config spec generated by this fetcher.
-            Please note that the SRCREV loses its functionality if you specify
-            this variable. SRCREV is still used to label the archive after a fetch,
-            but it doesn't define what's fetched.
-
-User credentials:
-    cleartool:
-            The login of cleartool is handled by the system. No special steps needed.
-
-    rcleartool:
-            In order to use rcleartool with authenticated users an `rcleartool login` is
-            necessary before using the fetcher.

-BitBake SFTP Fetch implementation
-
-Class for fetching files via SFTP. It tries to adhere to the (now
-expired) IETF Internet Draft for "Uniform Resource Identifier (URI)
-Scheme for Secure File Transfer Protocol (SFTP) and Secure Shell
-(SSH)" (SECSH URI).
-
-It uses SFTP (as to adhere to the SECSH URI specification). It only
-supports key based authentication, not password. This class, unlike
-the SSH fetcher, does not support fetching a directory tree from the
-remote.
-
-  http://tools.ietf.org/html/draft-ietf-secsh-scp-sftp-ssh-uri-04
-  https://www.iana.org/assignments/uri-schemes/prov/sftp
-  https://tools.ietf.org/html/draft-ietf-secsh-filexfer-13
-
-Please note that '/' is used as host path seperator, and not ":"
-as you may be used to from the scp/sftp commands. You can use a
-~ (tilde) to specify a path relative to your home directory.
-(The /~user/ syntax, for specyfing a path relative to another
-user's home directory is not supported.) Note that the tilde must
-still follow the host path seperator ("/"). See exampels below.
-
-Example SRC_URIs:
-
-SRC_URI = "sftp://host.example.com/dir/path.file.txt"
-
-A path relative to your home directory.
-
-SRC_URI = "sftp://host.example.com/~/dir/path.file.txt"
-
-You can also specify a username (specyfing password in the
-URI is not supported, use SSH keys to authenticate):
-
-SRC_URI = "sftp://user@host.example.com/dir/path.file.txt"
