3 Canonical Confidential Ubuntu Hardware Summit. December 8th 2011

Where we started

● First Started working on Ubuntu ARM in October 2008

● First release in April 2009 (9.04) supporting the Freescale iMX51 development platform. Ubuntu is the first commercially supported general purpose Linux

distribution for ARM

● Derived from Debian

● Complete port, Debian is ARMv4 compatible, Ubuntu target is ARMv7 THUMB2, floating point, NEON in library’s

● First release is ARMv5 and above compatible

Moving forward

● Four more releases, every 6 months, supporting a variety of SoC's (Freescale, Marvell, and TI OMAP 3 & 4

● ARMv7 and above compatible, and meets Ubuntu targets for THUMB 2,

floating point and NEON support.

5 Canonical Confidential Ubuntu Hardware Summit. December 8th 2011

Where we are today

● Sixth release in October 2011 (11.10) supports the TI OMAP 3 BeagleBoard, and the TI OMAP 4 PandaBoard, Freescale iMX53 Quickstart platform, and the Nvidia Tegra 2 SoC in the form of the Toshiba AC-100 Netbook

● The sixth release also was the technical preview of the Ubuntu ARM server

image, on the TI OMAP 4 PandaBoard.

● Headless

● Pipe cleaner release to validate all server software on ARM is SMP safe and works as expected.

6 Canonical Confidential Ubuntu Hardware Summit. December 8th 2011

The Future

● Seventh release to be in April 2012 (12.04) will support the TI OMAP 3 BeagleBoard, and the TI OMAP 4 PandaBoard, Freescale iMX53 Quickstart platform

● Ubuntu ARM Server OS released as the first ARM Long Term Supported (LTS) supporting Calxeda and other Quad Core Server class SoC's

● Linux Containers (LXC) and OpenStack well supported on ARM

● Ubuntu is optimized for best through put and lest power consumption and heat generation.

7 Canonical Confidential Ubuntu Hardware Summit. December 8th 2011

The Future

● Eighth release to be in October 2012 (12.10) client support continues

● Ubuntu Server released supporting Calxeda and other Quad Core Server class SoC's

● Optimizations continue to get best power performance per watt possible

● First OS to support ARM Cortex A15 SoC

● Virtualization support on ARM

● KVM

● XEN

● 40-bit Large Physical Address Extensions (LPAE) addressing up to 1 TB of RAM

● First dot release of 12.04 LTS adding some Quad core A9 and A15 SoC's to the LTS release

● Ubuntu ARM for ARMv8 64 bit SoC work starts

8 Canonical Confidential Ubuntu Hardware Summit. December 8th 2011

The Future

● Ninth and Tenth releases of Ubuntu OS

● April 2013 (13.04) and October 2013 (13.10) respectively

● Client support continues

● Ubuntu 32 bit Server releases continues to support Enterprise Level ARM

Server hardware:

● Cortex A8

● Cortex A9

● Cortex A15

● Cortex A7 Added

● Supporting Big Little processing

9 Canonical Confidential Ubuntu Hardware Summit. December 8th 2011

The Future

● Ninth and Tenth releases of Ubuntu OS (continued)

● First OS to support ARMv8 true 64 bit SoC's

● UEFI boot method supported

● Theoretically max RAM 16 exabytes,

● Limited by actual hardware

● Ubuntu supports Multiarch

● Allows running 32 bit applications and/or, 64 bit applications on the same machine at the same time. Allowing best use of system RAM and resources for least Power Consumption

10 Canonical Confidential Ubuntu Hardware Summit. December 8th 2011

The Future

● 2014 and 2015 Ubuntu ARM releases

● Client continues to be supported

● Server support 32 bit and 64 bit

● Unified single ARM kernel support s all SOC's

● Unified boot methods UEFI)

● Single image supports all ARM hardware (like in X86 Ubuntu) space
