Linaro Connect Asia 2014 Opening Keynote – Status and Future of ARMv8 Linux & Android [Video]

March 3rd, 2014 No comments

Linaro Connect Asia 2014 has just started in Macau today and will take place until Friday. You can follow the sessions live and/or their recordings via Linaro OnAir YouTube Channel. I’ve watched the opening keynote, and embedded the video at the bottom of this post. The keynote focuses on ARMv8 for Linux and Android on servers, mobile devices, digital home, and more, and involves two main speakers: George Grey, Linaro CEO , and Jon Masters, Chief ARM Architecture at Red Hat.

Linaro_Connected_Asia_2014

The speaker beginning of the video provides some practical information and the schedule for Linaro Connect. The keynote itself really starts around 15:50 with George Grey who spends the first 10 minutes introducing the latest Linaro members: Qualcomm, Mediatek, ZTE, AllWinner and Comcast. He then talks about the new Mobile sub-committee (MOBSCOM) that will focus on big.LITTLE, Android optimization and Android on ARMv8, as well as the soon-to-be-announced Linaro Digital Home Group composed of AllWinner, ARM, Comcast, Fujitsu, HiSilicon, and STMicro, that will work on STB / IPTV software implementation such as secure media playback. A large part of the talk is about boot architecture (ACPI, UEFI, ARM Trusted firmware…), and the debates ACPI vs FDT (Device Tree), U-boot vs UEFI, and so on. Other subjects discussed are ARM security with the recently formed Security Working Group, Virtualization, Middleware working on Aarch64 (LAMP and OpenJDK) and Android on 64-bit. The latter will require a lot more work, and actual hardware for validation of the work done on ARMv8 fast models, and to speed up code development. Finally he quickly mentions Linaro is still working on ARMv7 architecture, and preliminary work is done for Cortex-M with Yocto/OpenEmbedded support.

At the 50 minutes mark, Jon Masters takes over to talk about 64-bit ARM servers. He stresses several key points for ARM to be successful in the server market:

  1. Upstream first (to kernel.org), as Red Hat will only use code from mainline for servers
  2. Single binary required
  3. Must follow standards (SBSA, ACPI, UEFI…)
  4. Default to open (source and communication)

He explains that compared to last year hardware is now available, talks about hyperscale computing, and mention the “up to 25% market share for ARM servers in 2019″ quote from AMD. He explains there are challenges however, and the server market is much different from the embedded world, so CENH (Cute Embedded Nonsense Hacks) are not allowed for ARM servers. Long term (10+ years) support for toolchain and kernel are needed, with backports if necessary, and Fedora/Red Hat will never ever release an OS with a device tree file and/or U-Boot.

Finally he announces a Red Hat ARM Server Developer Preview will be released later this year, compliant with SBSA, and using UEFI and ACPI, and show demo running on Applied Micro X-gene Mustang board running an early version of the developer preview which boots with UEFI, and supports ACPI.

Watch the full keynote below for details (1h30).

Other interesting development include an initial arm64 Ubuntu saucy rootfs (that one?), work to support octa-core 4x Cortex A53, 4x Cortex A57 SoCs, an Android 4.4 KitKat LEB for the Galaxy Nexus, and ARMv8 LSK and Nexus7_2013-AOSP builds have been setup and Android can be now built using llvm-clang toolchain with the related patches submitted to upstream.

On a related note, there are also some Midway and Highbank engineering build images for Calxeda server processors, which may not be that useful going forward, as unfortunately the company has just closed door after running out of cash.

Here are the highlights of this release:

  • Linux Linaro 3.13-rc3-2013.12 released
    • Gator version 5.16 (same version as in 13.10 release)
    • New linaro-android-3.13-merge topic by John Stultz
    • IKS topics removed, as the code has been accepted into the mainline
    • Uprobes updated to v4
    • Updated big-LITTLE-pmu topic from ARM LT
    • Updated basic Capri board support from Broadcom LT (Kona PWM controller and backlight support added, bcm_defconfig updated)
    • Updated big endian topic
    • Updated topic to support K3V2 board from Hisilicon LT
    • Updated Versatile Express patches from ARM LT
    • VExpress64 support (FVP Base and Foundation models)
    • Config fragments changes – Arndale config fragment updated for 3.13 kernel to get USB (and hence the ethernet) working again, CONFIG_IP[V6]_NF_TARGET_MASQUERADE=m added to distribution.conf for libvirt/openstack, WiFi driver enabled in panda.conf (Panda 4460 only), and capri.conf created for the Broadcom Capri board
  • Linaro OpenEmbedded baseline updates
    • OpenDataPlane recipe added
    • Linaro Powerdebug recipe added
    • ACPICA updated to 20131115
    • Initscript for Gator added
  • Linaro Ubuntu baseline updates
    • Upgraded baseline to Ubuntu 13.10 (Saucy Salamander)
    • Initial Ubuntu ARM64 rootfs is available
  • Linaro Android baseline updates – Upgraded baseline to Android 4.4r2
  • Linaro UEFI 2013.12 released – Rebased to Tianocore EDK2 SVN revision 14795
  • Linaro PM-QA 0.4.6-2013.12 released – cpuhotplug test: wait for udev manager to start,cpufreq test: for per-policy governor case, check different paths

Toradex modules are often used in industries that requires long term availability, and Colibri VF50/VF61 SoMs will be available until 2028, for a cool 15 years.

Both SoM support embedded Linux 3.0.15 (OpenEmbedded), Windows CE 5.0/6.0, as well as Android (on request), and Colibri VF61 also supports Freescale MQX running on the Cortex-M4 core. Information to get started with WinCE (Coming soon) or Linux can be accessed on their Wiki for VF50 and VF61.

I’ve noticed the SoM thanks to a video by Charbax (embedded at the bottom of the post) where we can see different baseboards (carrier boards) starting from their large and versatile Colibri Evaluation Board, to the tiny, yet functional, Iris carrier board (pictured below without SoM) that reminds me of the recent Improv (EOMA68) board, at least when it comes to form factor.

Toradex Iris Baseboard

The board features DVI-I connector, as well as RGB and LVDS interfaces, a4/5 wire touch connector, an 10/100M Ethernet RJ45 connector, USB host and OTG ports, an header for 2x RS232 ports, an RTC clock with battery slot, and a 40-pin header with access to GPIO, I2C, SPI, PWM, and ADC pins.

Like most other system / computer on module companies, Toradex won’t release the complete hardware files for their SoMs, but they are more than happy to provide the full schematics (PDF and Altium), BoM, PCB layout, gerber, and manufacturing instructions files for their carrier boards so that customers can easily adapt them to their solution(s).

Colibri VF50/VF61 are available now. VF50 goes for as little as 19 Euros (MOQ: 10,000) to 33 Euros for single order, and VF61 costs as low as 28 Euros per unit for 10,000 pieces orders, and 49 Euros for one module. Iris carrier board are been around since 2011, and can be purchased for 32 Euros for 500 pieces order, or 59 Euros for one piece. So If you want carrier board plus VF50 SoM for evaluation it would cost 92 Euros (~$125), plus VAT if application, plus shipping.

Further information about the modules, and carrier boards, can be found on Toradex Colibri ARM computer modules page.
