-<chapter id='bsp'> - - <title>Board Support Packages (BSP) - Developers Guide</title> - - <para> - A Board Support Package (BSP) is a collection of information that - defines how to support a particular hardware device, set of devices, or - hardware platform. - The BSP includes information about the hardware features - present on the device and kernel configuration information along with any - additional hardware drivers required. - The BSP also lists any additional software - components required in addition to a generic Linux software stack for both - essential and optional platform features. - </para> - - <para> - This section (or document if you are reading the BSP Developer's Guide) defines - a structure for these components - so that BSPs follow a commonly understood layout. - Providing a common form allows end-users to understand and become familiar - with the layout. - A common form also encourages standardization - of software support of hardware. - </para> - - <para> - The proposed format does have elements that are specific to the Poky and - OpenEmbedded build systems. - It is intended that this information can be - used by other systems besides Poky and OpenEmbedded and that it will be simple - to extract information and convert it to other formats if required. - Poky, through its standard layers mechanism, can directly accept The format - described as a layer. - The BSP captures all - the hardware-specific details in one place in a standard format, which is - useful for any person wishing to use the hardware platform regardless of - the build system they are using. - </para> - - <para> - The BSP specification does not include a build system or other tools - - it is concerned with the hardware-specific components only. - At the end - distribution point you can ship the BSP combined with a build system - and other tools. - However, it is important to maintain the distinction that these - are separate components that happen to be combined in certain end products. - </para> - - <section id="bsp-filelayout"> - <title>Example Filesystem Layout</title> - - <para> - The BSP consists of a file structure inside a base directory, which uses the following - naming convention: - <literallayout class='monospaced'> - meta-<bsp_name> - </literallayout> - "bsp_name" is a placeholder for the machine or platform name. - Here are some example base directory names: - <literallayout class='monospaced'> - meta-Emenlow - meta-intel_n450 - meta-oaktrail - </literallayout> - </para> - - <para> - The file structure inside the base directory takes on the following form: - <programlisting> -meta-<bsp_name>/ -meta-<bsp_name>/binary/zImage -meta-<bsp_name>/binary/poky-image-minimal.directdisk -meta-<bsp_name>/conf/layer.conf -meta-<bsp_name>/conf/machine/*.conf -meta-<bsp_name>/conf/machine/include/tune-*.inc -meta-<bsp_name>/recipes-kernel/bootloader/bootloader_0.1.bb -meta-<bsp_name>/recipes-kernel/linux/linux-bsp-2.6.50/*.patch -meta-<bsp_name>/recipes-kernel/linux/linux-bsp-2.6.50/defconfig-bsp -meta-<bsp_name>/recipes-kernel/linux/linux-bsp_2.6.50.bb -meta-<bsp_name>/recipes-<bsp_name>/modem/modem-driver_0.1.bb -meta-<bsp_name>/recipes-<bsp_name>/modem/modem-daemon_0.1.bb -meta-<bsp_name>/recipes-<bsp_name>/image-creator/image-creator-native_0.1.bb -meta-<bsp_name>/prebuilds/ - </programlisting> - </para> - - <para> - The following sections detail what these files and directories could contain. - </para> - - </section> - - <section id="bsp-filelayout-binary"> - <title>Pre-built User Binaries (meta-<bsp_name>/binary/*)</title> - - <para> - This optional area contains useful pre-built kernels and userspace filesystem - images appropriate to the target system. - You can use these kernels and images to get a system running and quickly get started - on development tasks. - The exact types of binaries present are highly hardware-dependent. - However, a README file should be present that explains how to use the kernels and - images with the target hardware. - If pre-built binaries are present, source code to meet licensing requirements must also - be provided in some form. - </para> - </section> - - <section id='bsp-filelayout-layer'> - <title>Layer Configuration (meta-<bsp_name>/conf/layer.conf)</title> - - <para> - This file identifies the structure as a Poky layer, identifies the - contents of the layer, and contains information about how Poky should use - it. - Generally, a standard boilerplate file such as the following works: - </para> - - <para> - <programlisting> -# We have a conf directory, add to BBPATH -BBPATH := "${BBPATH}:${LAYERDIR}" - -# We have a recipes directory containing .bb and .bbappend files, add to BBFILES -BBFILES := "${BBFILES} ${LAYERDIR}/recipes/*/*.bb \ ${LAYERDIR}/recipes/*/*.bbappend" - -BBFILE_COLLECTIONS += "bsp" -BBFILE_PATTERN_bsp := "^${LAYERDIR}/" -BBFILE_PRIORITY_bsp = "5" - </programlisting> - </para> - - <para> - This file simply makes BitBake aware of the recipes and configuration directories. - This file must exist so that Poky can recognize the BSP. - </para> - </section> - - <section id="bsp-filelayout-machine"> - <title>Hardware Configuration Options (meta-<bsp_name>/conf/machine/*.conf)</title> - - <para> - The machine files bind together all the information contained elsewhere - in the BSP into a format that Poky can understand. - If the BSP supports multiple machines, multiple machine configuration files - can be present. - These filenames correspond to the values to which users have set the MACHINE variable. - </para> - - <para> - These files define things such as the kernel package to use - (PREFERRED_PROVIDER of virtual/kernel), the hardware drivers to - include in different types of images, any special software components - that are needed, any bootloader information, and also any special image - format requirements. - </para> - - <para> - At least one machine file is required for a Poky BSP layer. - However, you can supply more than one file. - </para> - </section> - - <section id="bsp-filelayout-tune"> - <title>Hardware Optimization Options (meta-<bsp_name>/conf/machine/include/tune-*.inc)</title> - - <para> - These files are shared hardware "tuning" definitions and are commonly used to - pass specific optimization flags to the compiler. - An example is <filename>tune-atom.inc</filename>: - </para> - <para> - <programlisting> -BASE_PACKAGE_ARCH = "core2" -TARGET_CC_ARCH = "-m32 -march=core2 -msse3 -mtune=generic -mfpmath=sse" - </programlisting> - </para> - <para> - This example defines a new package architecture called "core2" and uses the - specified optimization flags, which are carefully chosen to give best - performance on atom processors. - </para> - <para> - The tune file would be included by the machine definition and can be - contained in the BSP or referenced from one of the standard core set of - files included with Poky itself. - </para> - <para> - Both the base package architecuture file and the tune file are optional for a Poky BSP layer. - </para> - </section> - - <section id='bsp-filelayout-kernel'> - <title>Linux Kernel Configuration (meta-<bsp_name>/recipes-kernel/linux/*)</title> - - <para> - These files make up the definition of a kernel to use with this hardware. - In this case, it is a complete self-contained kernel with its own - configuration and patches. - However, kernels can be shared between many machines as well. - Following is an example: - <programlisting> -meta-Emenlow/recipes-kernel/linux/linux-bsp_2.6.50.bb - </programlisting> - This example file is the core kernel recipe that details from where to get the kernel - source. - All standard source code locations are supported. - Consequently, the source could be a release tarball, a git repository, or source included in - the directory within the BSP itself. - </para> - <para> - The file then contains information about what patches to apply and how to configure and build them. - Because the file can reuse the main Poky kernel build class, the definitions here can - remain very simple. - </para> - <para> - <programlisting> -linux-bsp-2.6.50/*.patch - </programlisting> - </para> - <para> - The above example file contains patches you can apply against the base kernel, from wherever - they may have been obtained. - </para> - <para> - <programlisting> -meta-Emenlow/recipes-kernel/linux/linux-bsp-2.6.50/defconfig-bsp - </programlisting> - </para> - <para> - Finally, this last example file contains kernel configuration information. - </para> - <para> - Examples of kernel recipes are available in Poky itself, and thus, make these files optional. - However, it would be unusual not to have a kernel configuration. - </para> - </section> - - <section id='bsp-filelayout-packages'> - <title>Other Software (meta-<bsp_name>/recipes-kernel/*)</title> - - <para> - This section describes other pieces of software that the hardware might need for best - operation. - Examples show some of the things you could encounter. - The examples are standard <filename>.bb</filename> file recipes in the - usual Poky format. - You can include the source directly by referring to it in the source control system or - the released tarballs of external software projects. - You only need to provide these types of files if the platform requires them. - </para> - <para> - The following file is a bootloader recipe that can be used to generate a new - bootloader binary. - Sometimes these files are included in the final image format and are needed to re-flash hardware. - </para> - <para> - <programlisting> -meta-Emenlow/recipes-kernel/bootloader/bootloader_0.1.bb - </programlisting> - </para> - <para> - These next two files are examples of a hardware driver and a hardware daemon that might need - to be included in images to make the hardware useful. - Although the example uses "modem" there may be other components needed, such as firmware. - </para> - <para> - <programlisting> -meta-Emenlow/recipes-Emenlow/modem/modem-driver_0.1.bb -meta-Emenlow/recipes-Emenlow/modem/modem-daemon_0.1.bb - </programlisting> - </para> - <para> - Sometimes the device needs an image in a very specific format so that the update - mechanism can accept and re-flash it. - Recipes to build the tools needed to do this can be included with the BSP. - Following is an example. - </para> - <para> - <programlisting> -meta-Emenlow/recipes-Emenlow/image-creator/image-creator-native_0.1.bb - </programlisting> - </para> - </section> - - <section id='bs-filelayout-bbappend'> - <title>Append BSP-Specific Information to Existing Recipes</title> - <para> - Suppose you have a recipe such as "pointercal" that requires machine-specific information. -
