Developing libreboot

-

- This section relates to building libreboot from source, and - working with the git repository. -

-

- Or Back to main index. -

- - -
- -

Install build dependencies

- -

- Before doing anything, you need the dependencies first. This is true if - you want to build libreboot from source, with either libreboot_src.tar.xz or git. - If you are using libreboot_bin.tar.xz (binary archive) then you can ignore this, because - ROM images and statically compiled executables for the utilities are included. -

Building libreboot from source

+

+ This section relates to building libreboot from source, and + working with the git repository. +

-

- For all other GNU/Linux distributions, you may have to adapt these scripts. By all means send patches! -

- -
- -

Get the full source code from metadata (git clone)

- -

- If you downloaded libreboot from git, then there are some steps to download and patch - the source code for all relevant dependencies. The archive in the git repository used to be - available as a tarball called 'libreboot_meta.tar.gz'. It contains 'metadata' (scripts) - which define how the source was created (where it came from). -

- -

- You can use the scripts included to download everything. -

- -

- First, install the build dependencies. -

- -

- Since libreboot makes extensive use of git, you need to configure git properly. If you have not yet configured - git, then the minimum requirement is:
- $ git config --global user.name "Your Name"
- $ git config --global user.email your@emailaddress.com
- This is what will also appear in git logs if you ever commit your own changes to a given repository. For - more information, see http://git-scm.com/doc. -

- -

- Another nice config for you (optional, but recommended):
- $ git config --global core.editor nano
- $ git config --global color.status auto
- $ git config --global color.branch auto
- $ git config --global color.interactive auto
- $ git config --global color.diff auto -

- -

- After that, run the get script:
- $ ./getall -

- -

- What this did was download everything (grub, coreboot, memtest86+, bucts, flashrom) - at the versions last tested for this release, and patch them. Read the script - in a text editor to learn more. -

- To build the ROM images, see #build. -

How to build "bucts" (for LenovoBIOS X60/X60S/X60T/T60)

- -

- This is for Lenovo BIOS users on the ThinkPad X60/X60S, X60 Tablet and T60. If you have coreboot or libreboot running already, ignore this. -

- -

- Bucts is needed when flashing in software the X60/X60S/X60T/T60 ROM while Lenovo BIOS is running; - external flashing will be safe regardless. - Each ROM contains identical data inside the two final 64K region in the file. - This corresponds to the final two 64K regions in the flash chip. Lenovo BIOS will prevent you from writing the - final one, so running "bucts 1" will set the machine to boot from the other block instead (which - is writeable along with everything beneath it when using a patched flashrom. see #build_flashrom). - After shutting down and booting up after the first flash, - the final 64K block is writeable so you flash the ROM again with an unpatched flashrom and run "bucts 0" to - make the machine boot from the normal (highest) block again. -

- -

- BUC.TS utility is included in libreboot_src.tar.xz and libreboot_bin.tar.xz.
- If you downloaded from git, follow #build_meta before you proceed. -

- -

- "BUC" means "Backup Control" (it's a register) and "TS" means "Top Swap" - (it's a status bit). Hence "bucts" (BUC.TS). TS 1 and TS 0 corresponds to bucts 1 and bucts 0. -

- -

- If you have the binary release archive, you'll find executables under ./bucts/. Otherwise if you need to build from source, continue reading. -

- -

- First, install the build dependencies. -

+
-

- To build bucts, do this in the main directory:
- $ ./builddeps-bucts -

+

Install build dependencies

-

- The "builddeps" script in libreboot_src also makes use of builddeps-bucts. -

+

+ Before doing anything, you need the dependencies first. This is true if + you want to build libreboot from source, with either libreboot_src.tar.xz or git. + If you are using libreboot_bin.tar.xz (binary archive) then you can ignore this, because + ROM images and statically compiled executables for the utilities are included. +

How to build "flashrom"

+
-

- Flashrom is the utility for flashing/dumping ROM images. This is what you will use to install libreboot. -

+

Get the full source code from metadata (git clone)

-

- Flashrom source code is included in libreboot_src.tar.gz and libreboot_bin.tar.gz.
- If you downloaded from git, follow #build_meta before you proceed. -

- -

- If you are using the binary release archive, then there are already binaries included - under ./flashrom/. The flashing scripts will try to choose the correct one for you. Otherwise - if you wish to re-build flashrom from source, continue reading. -

Configuring libreboot

+
-

- Before building a ROM in libreboot (or coreboot, for that matter), you need to configure it. - This is done using the following inside the source tree:
- $ cd coreboot/
- $ make menuconfig -

+

How to build "bucts" (for LenovoBIOS X60/X60S/X60T/T60)

-

- If you've already built a kernel before, you know how to use this interface. -

+

+ This is for Lenovo BIOS users on the ThinkPad X60/X60S, X60 Tablet and T60. If you have coreboot or libreboot running already, ignore this. +

-

- Configurations are then saved as files called ".config". Copies of each configuration used - for each machine type by the libreboot build scripts are stored in resources/libreboot/config/ -

+

+

- Specifically, it's good practise to enter the same information for libreboot that you found when running this - with the original BIOS or firmware. libreboot has already done this for you. This information is for reference, - in the hope that it will be useful. + If you have the binary release archive, you'll find executables under ./bucts/.

How to build the ROM images!

+
-

You don't need to do much, as there are scripts already written for you that can build everything automatically.

+

Configuring libreboot

-

- You can build libreboot from source on a 32-bit (i686) or 64-bit (x86_64) system. Recommended (if possible): x86_64. - On a ThinkPad T60, you can replace the CPU (Core 2 Duo T5600, T7200 or T7600. T5600 recommended) for 64-bit support. - On an X60s, you can replace the board with one that has a Core 2 Duo L7400 (you could also use an X60 Tablet board with the same CPU). - On an X60, you can replace the board with one that has a Core 2 Duo T5600 or T7200 (T5600 is recommended). All MacBook2,1 laptops - are 64-bit, as are all ThinkPad X200, X200S and X200 Tablet laptops. Warning: MacBook1,1 laptops are all 32-bit only. -

+

+ Before building a ROM in libreboot (or coreboot, for that matter), you need to configure it. + This is done using the following inside the source tree:
+ $ cd coreboot/
+ $ make menuconfig +

-

- First, install the build dependencies. -

-

- If you downloaded libreboot from git, refer to #build_meta. -

+

+ If you've already built a kernel before, you know how to use this interface. +

-

If running for the first time, run this:
- $ ./buildall (also performs the "./build" step below)
- Or if you only want to build dependencies (crossgcc, grub and so on):
- $ ./builddeps

+

+ Configurations are then saved as files called ".config". Copies of each configuration used + for each machine type by the libreboot build scripts are stored in resources/libreboot/config/ +

-

If you've already run ./builddeps and/or ./buildall before, you don't need to run them again. - Just run that from now on to build the ROM images:
- $ ./build

To un-build (clean) the build dependencies that you built before, do the following:
- This also deletes the ROM images under ./bin/:
- $ ./cleandeps

How to build the ROM images!

Preparing release archives (optional)

+

You don't need to do much, as there are scripts already written for you that can build everything automatically.

- Run that script:
- $ ./build-release + You can build libreboot from source on a 32-bit (i686) or 64-bit (x86_64) system. Recommended (if possible): x86_64. + On a ThinkPad T60, you can replace the CPU (Core 2 Duo T5600, T7200 or T7600. T5600 recommended) for 64-bit support. + On an X60s, you can replace the board with one that has a Core 2 Duo L7400 (you could also use an X60 Tablet board with the same CPU). + On an X60, you can replace the board with one that has a Core 2 Duo T5600 or T7200 (T5600 is recommended). All MacBook2,1 laptops + are 64-bit, as are all ThinkPad X200, X200S and X200 Tablet laptops. Warning: MacBook1,1 laptops are all 32-bit only.

- If you are building on an i686 host, this will include statically linked 32-bit binaries in the binary release archive that you created, - for: nvramtool, cbfstool, bucts, flashrom, ich9deblob, cbmem. + First, install the build dependencies.

-

- If you are building on an x86_64 host, this will include statically linked 32- and 64-bit binaries for cbmem, ich9deblob, cbfstool and nvramtool, while flashrom - and bucts will be included only as 64-bit statically linked binaries. To include a statically linked flashrom and bucts for i686, you - will need to build them on a chroot, a virtual machine or a real 32-bit system. You can find the build dependencies for these packages listed in deps-* + If you downloaded libreboot from git, refer to #build_meta.

+ +

If running for the first time, run this:
+ $ ./buildall (also performs the "./build" step below)
+ Or if you only want to build dependencies (crossgcc, grub and so on):
+ $ ./builddeps

+ +

If you've already run ./builddeps and/or ./buildall before, you don't need to run them again. + Just run that from now on to build the ROM images:
+ $ ./build

+ +

To un-build (clean) the build dependencies that you built before, do the following:
+ This also deletes the ROM images under ./bin/:
+ $ ./cleandeps

+ +

Note: after running 'cleandeps', you will need to run 'builddeps' or 'buildall' again before you can use 'build'.

+ +

After 'build' or 'buildall' has finished, you'll find the ROM images for each machine under ./bin/

+ +
+ +

Preparing release archives (optional)

+ +

+ Run that script:
+ $ ./build-release +

+ +

+ If you are building on an i686 host, this will include statically linked 32-bit binaries in the binary release archive that you created, + for: nvramtool, cbfstool, bucts, flashrom, ich9deblob, cbmem. +

+ +

+ If you are building on an x86_64 host, this will include statically linked 32- and 64-bit binaries for cbmem, ich9deblob, cbfstool and nvramtool, while flashrom + and bucts will be included only as 64-bit statically linked binaries. To include a statically linked flashrom and bucts for i686, you + will need to build them on a chroot, a virtual machine or a real 32-bit system. You can find the build dependencies for these packages listed in deps-* +

+ +

+ armv7l binaries (tested on a BeagleBone Black) are also included in libreboot_bin, for: +

+
    +
  • cbfstool
    • +
  • ich9gen
    • +
  • ich9deblob
    • +
  • flashrom
    • +
+ +

+ If you are building 32-bit binaries on a live system or chroot (for flashrom/bucts), you can use the following to statically link them:
+ $ ./builddeps-flashrom static
+ $ ./builddeps-bucts static +

+ +

+ The same as above applies for ARM (except, building bucts on ARM is pointless, and for flashrom + you only need the normal executable since the lenovobios_sst and _macronix executables are meant + to run on an X60/T60 while lenovo bios is present, working around the security restrictions). +

+ +

+ The script mkextbuild will generate a small source tarball called tobuild.tar.xz that + contains everything you need (including source) with which to build flashrom/bucts on these hosts. + The build-release script will have already executed this script for you, so the archive should + already exist. +

+ +

+ You'll find that the files libreboot_bin.tar.xz and libreboot_src.tar.xz have been created. +

How to add SeaBIOS to the ROM images

+

- armv7l binaries (tested on a BeagleBone Black) are also included in libreboot_bin, for: + SeaBIOS isn't really needed since libreboot uses the GRUB payload which + is much better (for several reasons), so it is no longer included in the ROM + images by default. Instead, you can add it afterwards.

-

- If you are building 32-bit binaries on a live system or chroot (for flashrom/bucts), you can use the following to statically link them:
- $ ./builddeps-flashrom static
- $ ./builddeps-bucts static + In the supplied binary archives, or in your own (if you did 'build-release') you can add SeaBIOS + to the ROM images, along with SeaVGABIOS which is a free/libre Video BIOS implementation that wraps + around the 'native graphics initializitation' code in coreboot, for boards that have support for it.
