T2/Linux Now on Snapdragon X1 Elite DevKit! 2025-06-10

We’ve hit another milestone in ultra-portable Linux support: T2/Linux now runs on the Qualcomm Snapdragon X1 Elite Dev Kit — originally designed for Windows-on-ARM.

Thanks to a generous hardware sponsor, we’ve brought T2/Linux up on this high-performance ARM64 desktop platform. But turning a proof-of-concept into a seamless Linux experience requires quite some integration work: device trees, firmware extraction, early graphics USB-C DisplayPort Alt-mode, and much more need to be correctly build, configured and intregrated in boot-loader, initrd, and installer.

We’re working hard to wire up everything needed for full installer support. Got a Snapdragon device or want to help? Let’s us know!

Trinity Desktop Environment Now Available in T2 2025-05-15

Doubling down on IA-64 Itanium support 2023-12-05

With the recently announced removal of support for IA-64 from the upstream Linux kernel, we would like to stress that the reports of death of this EPIC architecture are greatly exaggerated.

Due to the ease of T2’s cross compiling, as well as support and interest by the OpenSource community, we are committed to support IA-64 for at least another decade or two.

If anything, the upstream removal only sparked increased interest in T2 on Itanium support and brought an influx of new developers with IA-64 based machines. If you have highly reliable, explicit parallel IA-64 computers in production, don’t delay and try and support highly optimized T2 Linux today!

Dark theme and more 2023-08-28

Once a hacker niche now mainstream, and we could not escape it anymore: the Dark Theme! Accompanied by our new glowing T2 logo!!

Keeping this pace, we did a long awaited refactor on the website’s backend that will allow us keep making incremental changes to it with ease in the future. Who knows, maybe a complete design overhaul some day?

Article titles on the main page can now be clicked to highlight the article itself, which also gives you a nice link to share links directly pointing to the chosen article. For example the one you are currently reading /#news-2023-08-28

While at it, we finally added an RSS feed for the main page, too! Which truly helps to keep an eye on what is going in the open T2 world without having to constantly open a web browser daily to check for news.

Build time estimation 2023-07-31

Te are really happy to announce that, as of revision 64292, the T2 build scripts estimate and display how time time a package will likely require to build!

Of course if works for Emerge-Pkg as well as Build-Target.

This is a game changer for many users with different, especially older systems and especially when testing on multiple different, exotic, vintage and retro RISC machines with varying levels of performance and allows us to better organize around long builds!

This feature is based on binutils reference time units which were gathered for a really, really long time in T2 package’s .cache.

We tried to make it as accurate as possible, but of course some variations, especially for packages not utilizing multiple parallel threads during compilation are to be expected.

The T2 core developers updated a massive amount of .cache files to make this as accurate as possible.

And last but not least, we did benchmarks on multiple boards to give people an overview of what their hardware is capable of, which you can find under "Performance Index" on individual hardware reference page. See for example the Mango Pi MQ-Pro D1 T2 hardware page.

We hope you like this new feature, because we for sure do!

Intel hardware decoding 2023-07-06

We are happy to announce that T2, as of r63868, officially supports hardware video encoding and decoding with Intel discrete GPUs (aka ARC/DG2).

TL;DR: ./scripts/Emerge-Pkg -force intel-onevpl ffmpeg mpv

It required 40 hours of mostly nighttime work to put everything together but we finally did it.

Here are all the packages you need to operate your hardware en/decoder:

• libva
• onevpl
• intel-media-driver
• intel-gmmlib
• intel-onevpl
• ffmpeg to encode or decode AV1 files
• A video player like mpv or vlc (or a web browser) to watch AV1 content

Example command: ffmpeg -hwaccel qsv -c:v vp9_qsv -i input.webm -c:v av1_qsv -b:v 5M -look_ahead 1 output.webm

As an added bonus you also get H264, HEVC and VP9 hardware support!

As usual, patches welcome! Let us know if it actually works for your DG1 or Xe graphics too!

32-bit Rustc and more big-endian 2023-05-05

The last couple of days we spent fixing rustc support for sparc32, notably the elf format which isn’t working upstream as well as more RISCV(32) as well as big-endian ARM fixes!

Next release will then come with rustc, cargo and hopefully firefox which requires a more fixes at the time of writing.

As usual, patches welcome if you found something not yet working perfectly on this older, or embedded systems!

Complete system encryption 2023-02-18

In the past few weeks, we’ve been hard at work to improve user convenience when setting a fully encrypted T2 installation.

Our installer already supported full-disk encryption, including encrypted boot partitions which you unlock with Grub at boot time since 2020 (r50723). But until now we were missing a crucial feature for easier data management without being locked with one partition scheme unless doing a clean install: LVM inside LUKS.

As of today, we are proud to announce that we integrated support for booting LUKS+LVM! We even added support for encrypted swap/suspend-to-disk to complete the security chain so that you can shutdown you PC without closing everything you were working on and worry about someone running out with your drive and dumping the content of your swap partition in case your computer is stored in a public space.

Everything is integrated in Stone which you will be able to experiment by yourself when we release 23.2 ISO images.

Rebooting from the installed to the new system is now faster than ever, courtesy of the kexec mechanism that was added in r60600 (r59937, 60059, 60458, 60468, and more that fixed cross-compiling!). Meaning you can now deploy T2 on your server without having time to make coffee before it reboots!

Of course everything is already available in the current subversion repository! If you have an already existing T2 install make sure to upgrade the following packages before testing anything: grub2, linux, mkinitrd, stone, util-linux.

A typical LUKS+LVM+suspend-to-disk setup would look like so:

NAME               FSTYPE      TYPE  MOUNTPOINTS
sda                            disk
├─sda1             vfat        part  /boot/efi
└─sda2             crypto_LUKS part
└─toor                       crypt
├─qvo-swap     whatever    lvm   [SWAP]
├─qvo-root     whatever    lvm   /
├─qvo-boot     whatever    lvm   /boot
└─qvo-home     whatever    lvm   /home

You can watch parts of that work on youtube:

• Better and easier full-disk, swap and LVM encrypted Linux installation
• Encrypted LVM storage, kexec reboot & more

Next steps for us will be to have sensible defaults suggestions at partition time for user convenience and then rewrite (hopefully soon) a graphical version of the installer.

As always, patches welcome! Come chat with us on the interwebs!
