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

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.

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).
