Contents
'arm64' is the Debian port name for the 64-bit ARMv8 architecture, referred to as 'aarch64' in upstream toolchains (GNU triplet aarch64-linux-gnu)
Hardware (that actually works) started to becoming available in October 2013, but access was restricted. Debian has very kindly been donated two 8-core machines, installed in March 2014 running two buildds in Debian-ports. One has been split with xen so we also have a porterbox. The port was started in 2010 (by ARM and Linaro working with the community in commendable fashion) long before hardware was available so that there would be something to run when it arrives.
Hardware, emulators and models
Arm64 hardware is starting to become available from Q42013, but is not commercically available yet.
Arm64 qemu emulation (user-space only) became initially available in October 2013. It was added to qemu upstream in v2.0, and is available in Debian 8 (Jessie) onwards. This is much faster than the model for building software, but can't be used for kernel-space things like bootloader/kernel work, or anything that uses multithreading. See Qemu Rootfs below for details.
There is a (non-free, free beer) 'Foundation Model' simulator which can be used to run arm64 code, which is available here
Much of the work packagers need to worry about is updating autoconf, multiarch and cross-build fixes, with a few actual arm64 changes here and there, and doesn't actually need a model or emulator.
This is the first non-x86 self-bootstrapped Debian port: the first 150 packages cross-built using build-profiles to untangle cyclic build-dependencies.
Status
(last updated: May 2014)
Debian unstable is being bootstrapped in debian-ports: http://buildd.debian-ports.org/status/architecture.php?a=arm64&suite=sid
40% of Debian was built in mid-may.
Please check the packages in the 'Build Attempted' section there to see what needs fixing. Many of them are trivial fixes. (See bug-tracking below for info on bug-filing and resources on fixing).
Current blockers are reported at: http://people.debian.org/~zumbi/arm64/index.unstable.html
We hope the port will be in a fit state to release as an official architecture in Jessie, but right now there is still a lot to do.
Detailed status is below.
The initial port was done entirely as a cross-build using Ubuntu raring packages. It was done in Ubuntu because multiarch and the cross-toolchains were more advanced there than in Debian at the time, (late 2012) and Debian was frozen for Wheezy. The resulting image and updates were then used to natively build most of Saucy once real hardware that worked was available (to canonical). Then that image was used (in Qemu) to natively build a Debian buildd image.
Ubuntu Saucy and Trusty are 3/4 built (30,000 binaries) for arm64. The missing stuff is largely unported languages (haskell, mono, ruby, go, etc).
The initial Debian bootstrap (350 source, 2100 binaries) was built in a personal repo ). Debian arm64 is now debootstrappable from there.
This bootstrap was done natively starting with an Ubuntu Saucy base to supply a base chroot and non-library build-deps, lsb+dpkg-vendor was set to 'Debian', each package was built, uploaded and added to a Debianise script which replaced all available packages in the Saucy clean tarball chroot until it contained no Ubuntu packages and was effectively Debian unstable. Then a new clean debian chroot was deboostrapped and packages built/rebuilt in there using build profiles to break cycles.
There are crosstoolchains built for Raring/Saucy/Trusty. Debian cross-toolchains are being worked on.
Binutils, kernel, gcc and glibc port patches were sent upstream over the summer of 2012, with enough stuff to build a cross-toolchain available by October 2012. In Oct/Nov/Dec a quantal-based archive of base packages was built. In Jan 2013 the effort was switched to raring to take advantage of cross-build fixes, multiarch improvements, libc and arm64 updates going in there.
Current cross-buildability (in Ubuntu) for arm64 is tracked on this status page. Native buildability is tracked at http://qa.ubuntuwire.org/ftbfs/arm64.html.
Pre-built Rootfses
There are a selection of rootfses here in the form of tarballs and disk images, with and without qemu-static installed.
plain tarball rootfs
Debian: unstable debootstrap (77 MB) has no 'including' directory so designed to be unpacked onto a real machine or into a chroot dir. Includes qemu static binary for use with qemu 2.0 too.
Ubuntu saucy multiarch tarball suitable for use as a chroot on arm64 hardware. Identical in content to the foundation model disk image below. Adding qemu-static would make it useful under qemu. Configured for armhf/arm64 multiarch use.
qemu rootfs
Debian: unstable debootstrap (88MB)
Ubuntu: Ubuntu saucy tarball chroot (68MB), suitable for use with arm64 qemu (qemu-arm64 (static) is installed inside it).
To use arm64 qemu, just install it: apt-get install qemu-user-static on Debian unstable/Jessie. This binary installs fine on stable as well.(Older qemu released referenced on this page used a different name for the static binary and binfmt-misc config and thus will not interoperate).
Using The Foundation model
See https://wiki.debian.org/Arm64Port/raringbootstrap#Raring_rootfs_for_Foundation_model
Here is a Ubuntu saucy disk image (92MB compressed, 2G uncompressed). Suitable for use with the foundation model or real hardware. This image is configured for armhf/arm64 multiarch usage, but it's a one-liner to turn that off.
And here's a suitable kernel (3.13, linaro foundation release 2014-01), modified for use with Linux instead of OE.
Debootstrap arm64
Plain debootstrap will now produce an arm64 rootfs from the Debian Ports archive. ( I had to copy bcron.deb into the chroot and re-run debootstrap/debootstrap --second-stage to make it work - need to work out why debootstrap didn;t do that for me)
On an x86 machine, install qemu-user-static 2.0 or later (the package from unstable works fine on stable/testing), and: sudo qemu-debootstrap --arch=arm64 --no-check-gpg unstable debian-arm64 http://ftp.debian-ports.org/debian Will do the whole process (creating an unstable chroot in the 'debian-arm64' dir).
If you have hardware or want to do it on qemu or a model), use this command: sudo debootstrap --no-check-gpg unstable debian-arm64 http://ftp.debian-ports.org/debian
Inside the chroot change your sources.list to http://ftp.debian-ports.org unstable _and_ unreleased.
deb http://ftp.debian-ports.org/debian/ unstable main deb http://ftp.debian-ports.org/debian/ unreleased main
to have the latest packages available. (packages locally packaged for arm64 go into 'unreleased' until the fixed version is uploaded to debian-proper.
The old bootstrap repo at http://people.debian.org/~wookey/bootstrap/debianrepo2 is now obsolete and should not be used.
Porting packages for arm64 - Maintainer info
If your package does not build for arm64 it is usualy trivial to fix, but sometimes a bit harder and sometimes a big deal. Here is info on what to change and where to go for help, updates and info.
autoconf updating
Most packages just need updated autoconf config info which includes the new arch. It is now best practice for (autoconf-using) Debian packages to re-autoconf on every build in order to pick up this info automaticaly, or at least use the autotools-dev package to ensure latest config.sub and config.guess files. Good info on making these updates is on https://wiki.debian.org/qa.debian.org/FTBFS#A2014-01-21_using_dh-autoreconf_during_the_build
Packages that use CDBS (and autoconf) will automatically get updated config.sub and config.guess if autotools-dev is installed (it will not be automatically on buildds unles your package build-depends it (see Debianbug:744915) so until a better solution is found you'll need to add it to your build-deps).
Nomenclature and defines
If your package does architecture-specific things explicitly then you will need to understand what names to use in tests.
The gnu name for the architecture (as given to configure) is aarch64-linux-gnu.
The debian name for the architecture is arm64
GCC defines __aarch64__ for the architecture.
Be careful of things which check for arm* in debian architecture tests, as it is usually wrong to do the same thing for arm64 as for arm. In general, if you are not sure you should do the same thing as amd64 as that matches quite closely (64 bit, little endian, 32-bit ints and floats, 64-bit pointers, longs and doubles).
Check the link below for 'upstream package porting' to see if your package has had porting attention from Linaro.
There is also a big-endian version of the architecture/ABI: aarch64_be-linux-gnu but we're not supporting that in Debian (so there is no corresponding Debian architecture name) and hopefully will never have to. Nevertheless you might want to check for this by way of completeness in upstream code.
Useful porting docs
Bug tracking
Please tag all arm64/aarch64-specific bugs 'arm64' (user=debian-arm@lists.debian.org, tag=arm64 - ) in the BTS (see bugs.debian.org/usertags for instructions), or in launchpad.
Here is an example (assuming you have a patch file, and a body template file)
reportbug $package -V $version -A $patchfile --src --subject "Add arm64 support" --tag patch --pseudo-header 'User: debian-arm@lists.debian.org' --pseudo-header 'Usertag: arm64' --no-tags-menu --severity normal --body-file $template
Here is the current list of arm64 Debian bugs
Other distros often have useful bug-fixes already:
Upstream-relevant bugs should be filed in the linaro-aarch64 bug tracker to avoid distro duplication of effort. In this case, file bugs in the Debian BTS as well, then link to them in the Linaro tracker.
Repository
Raring, and unstable armv8 bootstrap repos have been set up here. These contain current state of play for modified tools, sources, cross-tools, and packages built for arm64. Notable packages include eglibc2.16, gcc-4.7, linux-source, arm64-cross-toolchain-base, gcc-4.7-aarch64-linux-gnu, dpkg (with build profile support), multiarch versions of perl and python2.7. A quantal chroot was used for initial work but is now (Dec 2012) frozen/abandonned.
You should just be able to add that repo and apt-get install crossbuild-essential-arm64 to get a working cross environment. If build and host arch packages have got out of sync this won't work, which happens often in raring and unstable.
Cross Toolchain
Before anything useful can happen dpkg needs to have arm64 support. This was done in v1.16.4
Toolchain Bootstrap
First job is to bootstrap a cross-toolchain so other stuff can be built.
This is relatively easy to do from upstream sources either directly or using a framework like ?OpenEmbedded, but to get a Debian-packaged toolchain easily usable in chroots, sbuild etc requires merging the new port with the Debian packaging, which is frankly a PITA.
When starting from scratch multiarch doesn't help you because you need eglibc:arm64 to make aarch64-linux-gnu-gcc and you need aarch64-linux-gnu-gcc to make eglibc:arm64. So you have to do a 3-stage bootstrap.
Ubuntu has (thanks to Linaro) a package to automate the building of fully-bootstrapped compilers for armhf/el so that was munged to make arm64-cross-toolchain-base, and the delighful task of getting everything working was started.
The process is:
- Make a binutils with aarch64 port and arm64 packaging in so you can build binutils-source
- Make a kernel with arm64 stuff in so you can build kernel-source
- Make a gcc with aarch64 gcc port and arm64 packaging in so you can build gcc-source
- Make an eglibc with aarch64 port and arm64 packaging in so you canbuild eglibc-source
- Make arm64-cross-toolchain-base with the right runes in it to build:
- munged linux-libc-dev kernel headers
- gcc stage1 bare cross c-compiler
- eglibc stage1 simple libc
- gcc stage2 compiler and cross-compiler and libraries
- eglibc stage 2 (full) build
- gcc stage3 (full) build
Easy peasy.
This work was initially done in Ubuntu due to better multiarch support, availability of *-cross-toolchain-base and newer eglibc.
Toolchain Bootstrap Issues
Quantal bootstrap
The initial arm64 packaged toolchain was done in Ubuntu Quantal, as the first release where multiarch crossbuilding basically worked. The details of this are documented on toolchain/BootstrapIssues#Quantal.
Raring bootstrap
Easier than quantal as all the base porting has already been done. However not quite as easy as one might like. arm64-cross-toolchain-base was updated with some fixes/updates from the armhf/armel-c-t-b packages. Binutils and linux-libc-dev headers were straightforward.
But gcc stage1 build fell over first with bugs in gcc-4.7.2-12ubuntu2 (patches that didn't apply, missing arm64 symbols-files). Then with missing bits/predefs.h header when building libgcc. This turned out to be 1091823.
Then the build completed but there was a libgconv.a packaging error for some reason. Updating to gcc-4.7-2-14ubuntu2 seemed to fix that.
Debian bootstrap
The Debian toolchain bootstrap is being attempted fully multiarch, to avoid the above issues with needing a separate libc:arm64 and equivs packages to make everything work. It's also an opportunity to integrate DEB_BUILD_PROFILE boostrap features to make it all nicely automatable, without toolchains being a special case in the archive. This was initially (December 2012) too troublesome, mostly due to new versions of GCC coming out every few days with this stuff being changed. As of gcc-4.7.2-18 onwards ThibG's patches for the toolchain using the multiarch system libraries are integrated so I had another go.
This process is documented on MultiarchCrossToolchains.
Current status is that experiemntal is being used as the stuff in unstable is too old.
binutils and gcc stage1 are built.
The kernel header patches are being updated for 3.8
Building packages
Given a cross-build chroot, in general you should be able to do
apt-get build-dep -aarm64 <package> apt-get source <package> cd <package>-<ver> CONFIG_SITE=/etc/dpkg-cross/cross-config.arm64 DEB_BUILD_OPTIONS=nocheck dpkg-buildpackage --preserve-env -aarm64
But there are of course some caveats.
Details on setting up an arm64 cross-chroot are given here: https://wiki.linaro.org/Platform/DevPlatform/CrossCompile/arm64bootstrap
There is no libssp (stack protection) support in aarch64 toolchain yet (Nov 2013, https://cards.linaro.org/browse/TCWG-23) so the -fstack-protector will cause an error:
/usr/lib/gcc/aarch64-linux-gnu/4.7/../../../../aarch64-linux-gnu/bin/ld: cannot find -lssp_nonshared /usr/lib/gcc/aarch64-linux-gnu/4.7/../../../../aarch64-linux-gnu/bin/ld: cannot find -lssp
For any package that uses dpkg-buildflags this is easy to fix by setting DEB_BUILD_MAINT_OPTIONS=hardening=-stackprotector You can set this for the whole build chroot if using one (probably best for now), or for a user, or for a build by doing:
DEB_BUILD_MAINT_OPTIONS=hardening=-stackprotector dpkg-buildpackage -aarm64
Better to fix this permanently in /etc/dpkg/buildflags:
STRIP CFLAGS -fstack-protector
Package porting
Many packages need no more than config.guess and config.sub updating to build for arm64. autotools got aarch64 support upstream in June 2012. So autotools-dev 20120608.1 has the files needed. However many (most) packages don't autoreconfig on build, or otherwise update those files so they have to be patched. A lot of boring patches were filed with the tag arm64, such as 689613
In many cases dh_autoreconf can be used to fix this without making horrible, unreadable, autofoo patches. Sometimes it's better to use autotools-dev which only updates config.{sub,guess} without re-generating all the configury because this is less invasive. dh-autoreconf is preferred as it covers more cases (for example the ppc64el port need re-libtooling, so dh-autoreconf works, but the autotools-dev dh_updateconfig is not sufficient. Some packages won't build a second time after dh_autoreconf has poked them around. This QA page goes into more details about updating your packages
For the initial botstrap everything had to be cross-built as there was no hardware (and no OS) so cross-building patches were also needed in many packages, and multiarch patches in many build-deps. Due to the Wheezy freeze and thus the more progressed state of multiarchification and more cross-build fixes in Ubuntu, this work was initialy done in a private Quantal-based repo, and later in a raring-tracking repo, but all bugs are either directly filed, or also pushed upstream to Debian. There are still (April 2014) a lot of cross-build fixes that are in Ubuntu but not yet uploaded to Debian.
Quite a few packages need actual changes. Here is a list so far:

Perl
Perl is a bit of a special case. It needs both cross-build support and multiarchifying. Status is being tracked on Multiarch/Perl
Cross-build supprt currently involves creating config files on a host-arch machine, which currently means a model, or creating the files by inspection and comparison with others. A set of arm64 configs has been created from a model run and comparison with armhf and amd64 configs for Debian and arm64 config for openembedded. These are now checked-in to perl-cross-debian. And perl cross-builds successfully with these configs and that version of perl-cross-debian plus its corresponding perl patches.
Meanwhile There is a multiarch branch of perl here: 'ntyni/multiarch-5.14' branch of git://git.debian.org/perl/perl.git which is discussed in this thread: http://lists.debian.org/debian-perl/2012/09/msg00000.html
This builds and works OK, but does not currently cross-build. Merging these two pieces of work to get a cross-buildable, multiarched, arm64, perl is currently underway.

Packages that are built for jessie
See the debian-ports status page: http://buildd.debian-ports.org/status/architecture.php?a=arm64&suite=sid
The initial bootstrap now has its own page, largely for historical interest: https://wiki.debian.org/Arm64Port/PackagesBuilt
Packages with issues
libcaca fails in
- 'make pdflatex refman'
something wrong with pdflatex? Hacky workaround patch
transfig failed to build: make[3]: Entering directory `/home/wookey/debian/transfig-3.2.5.e/fig2dev' make[3]: Warning: File `/usr/include/X11/Xlib.h' has modification time 2.3e+08 s in the future rm -f fig2dev.o gcc -c DefaultGcc2AArch64Opt -I.. -Dlinux -Daarch64 -D_POSIX_C_SOURCE=199309L -D_POSIX_SOURCE -D_XOPEN_SOURCE -D_BSD_SOURCE -D_SVID_SOURCE -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -DFUNCPROTO=15 -DNARROWPROTO -DNFSS -DUSE_INLINE -DI18N -DUSE_PNG -DUSE_XPM -I/usr/include/X11 -I/usr/include/X11 fig2dev.c gcc: error: DefaultGcc2AArch64Opt: No such file or directory This was same imake (xuitls-dev) issue that broke nas: 734944
w3m failed to build: first imlib2 bug 734425 has to be fixed But then the configury fails to add -lX11 to the link line so it fails to link. Both fixed in 0.5.3-14
fftw3 failed to build neon code (ICE) https://bugs.launchpad.net/linaro-aarch64/+bug/1267113 Simply not enabling neon for arm64 allows a build
guile-1.8 failed building tex tutorial. Upstream issue. Fixed in 711029
mksh segfaults in the tests (does not honour 'nocheck')
Packages that needed fixes
#util-linux apt-get install automake autopoint libtool # (29Mb of stuff) DEB_BUILD_OPTIONS="parallel=80" dpkg-buildpackage -sa > ../buildlog.util-linux-2.20.1 failedwith:
- CC fdisk-fdiskbsdlabel.o In file included from fdiskbsdlabel.c:62:0: fdiskbsdlabel.h:61:2: error: #error unknown architecture
The fix is in http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=689607
Having to add every new arch one by one to this package is silly. Listing the exceptions would be a lot more useful. Are there any?
#coreutils apt-get install dh-buildinfo groff gperf bison DEB_BUILD_OPTIONS="parallel=80" dpkg-buildpackage -sa fails to build:

see https://bugzilla.redhat.com/show_bug.cgi?id=917735 and http://gmplib.org:8000/gmp/rev/187b7b1646ee which says this is the same issue as fixed in gmp This is the bug: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=698330 Applying that fix (updated) works.
Using dose to see what is multiarch-buildable
Dose 3.1 can analyse build-dependencies for a given package, and understands about cross and multi-arch. It can tell you what is currently buildable given the current state of relevant source and package files. Use 3.1.2 for the --checkonly option and the --defaultedMAforeign option
Install it (it's in the bootstrap tools repo)
sudo apt-get install dose-builddebcheck
- -f shows packages you can't build
- -s shows packages you can build
- -e prints an explanation of what the problem is
- --checkonly checks just one package rather than everything
--defaultedMAforeign uses the Ubuntu apt algorithm (not in wheezy) of assuming all arch:all Build-Deps can be considered Multi-Arch:Foreign
To check
dose-builddebcheck -f --checkonly <package> \ --defaultedMAforeign --deb-native-arch=amd64 --deb-foreign-archs=arm64 --deb-host-arch=arm64 \ /var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_quantal_main_binary-amd64_Packages \ /var/lib/apt/lists/people.debian.org_%7ewookey_bootstrap_ubunturepo_dists_quantal-bootstrap_main_binary-amd64_Packages \ /var/lib/apt/lists/people.debian.org_%7ewookey_bootstrap_ubunturepo_dists_quantal-bootstrap_main_binary-arm64_Packages \ /var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_quantal_universe_source_Sources | grep source
