Linaro Security Working Group (SWG), Jens Wiklander, Joakim Bech, Pascal Brand and Cedric Chaumont are talking about what is happening within Linaro’s working group that handles security. The group is currently focusing on creating an open source Trusted Execution Environment (TEE) solution running on TrustZone® for ARMv7 and ARMv8 architecture. They also mention that they are going to work on secure boot (UEFI) and DRM schemes (EME) later on. According to SWG there has been and is a lot of interest shown from various companies, markets and countries. People have a hard time trusting a black box that is supposed to protect their most valuable assets. Therefore it is more than welcome to create an open source TEE solution right now, says SWG.

Sree Kotay, Comcast Chief Software Architect about starting the Linaro Home Group for optimizing Linux for the ARM Powered Set-top-box
Radically revamping the device development model for Carrier class operators with ARM and Linaro. Comcast? Software? Isn’t that an oxymorom? See how the open source community and modern development models are re-shaping the feature velocity and security models for embedded devices like set-top-boxes, cable modems and gateways. Competing in the modern landscape means building products and experiences that compete with a new breed of innovators. Comcast’s SVP, Engineering and Operations and Chief Software Architect will provide insight into how its reinvented its technology stack and product line.
my interview with him:
The new Linaro Home Group is about optimizing ARM Linux for Multimedia Set-top-boxes. Here’s my interview with Sree Kotay, Comcast Chief Software Architect about how Comcast is interested in working with Linaro to optimize Linux on the ARM Powered Set-top-box.

Pradeep Kathail, Cisco Chief Software Architect
The Linaro Networking Group marked its first anniversary at the Linaro Connect Asia. Here Bob Monkman, ARM Enterprise Segment Marketing Manager, interviews Pradeep Kathail, Cisco Chief Software Architect, Network Operating System Group, to reflect on the year’s accomplishments and current activity within LNG. In addition to delivering Big Endian support in the Linux kernel, LNG launched the OpenDataPlane (ODP) project to enable data plane applications to easily port across different hardware platforms and architectures while retaining the ability to exploit hardware acceleration features unique to each platform. Pradeep discusses the importance of ODP and its relationship to other open source initiatives like OpenDaylight (ODL) as part of the larger industry trends of Software Defined Networks (SDN) and Network Functions Virtualization (NFV).

HiSilicon D01, 16-core ARM Cortex-A15 presented by Huawei
Here’s the 16-core ARM Cortex-A15 processor from HiSilicon Huawei on a development board for ARM Powered Networking and Servers coming up. Hacked on in this video by Linaro Toolchain Engineer Rob Savoye (2), who now is climbing the Mount Everest. Linux kernel v3.13 is running on this board, with three SATA ports and two Gigabit ethernet ports driver ready. The BSP code will soon be upgraded to kernel v3.14 and be upstreamed in parallel. Source code and binaries are released through Linaro website. Ubuntu Server is verified on this board. In this demo, it runs a GCC toolchain native build. Linaro Toolchain Working Group plans to use this board to run multiple builds per board, to maximally saturate D01’s computing and storage capability.

Linaro VP of Engineering Mark Orvek talks Security with Joakim Bech and Kernel with Deepak Saxena
Mark Orvek, Linaro VP of Engineering chats with Joakim Bech, Tech Lead Security Working Group; and Deepak Saxena, Tech Lead Kernel Working Group about the work that their teams are focusing on in 2014.
Ongoing activity on the Energy Aware Scheduler
Linaro and ARM engineers talk about their current activities to integrate power management into the Linux scheduler. By integrating cpuidle and cpufreq mechanisms into the scheduler, they hope to work with the community to create an energy-aware scheduler as an alternative to the current performance-oriented scheduler. This work will require improvements in other parts of the scheduler such as better description of processor topology, load estimation in the scheduler and better tools to measure the performance impact of changes to the scheduler.
Linaro engineers implementing ACPI for ARMv8
Linaro is working on implementing ACPI for general purpose servers using the ARMv8 architecture. This has been controversial as it is a competing technology to FDT which has been used now for the 32bit ARM world.
ACPI has been chosen on for the general purpose servers to allow standard distributions such as RHEL and Ubuntu server to boot on hardware which they have no special support in the same way as x86 world. ACPI is used to abstract the hardware to the level the standard distribution can boot to the point it can be useful.
There is a large overlap between FDT and ACPI but they actually do things a different way. FDT is currently holding fast the the mobile and tablets market for ARM. But with Intel implementing ACPI phones and tablets nothing is certain for the future.

Linaro’s validation team demonstrates using LAVA for native toolchain builds and “hack” sessions on Arndale Octa and APM X-Gene ARMv8 platforms
Linaro’s automated validation architecture (LAVA) is typically used to execute automated tests to validate Linaro’s engineering output. However, LAVA has recently integrated features to automate builds and provide secure remote interactive sessions to developers. Linaro’s lab lead Dave Pigott shows a native toolchain build orchestrated by LAVA. This technology enables developers to validate the toolchain on many ARM processor designs as well as other architectures. Tyler Baker a technical architect at Linaro explains how LAVA abstracts the image deployment, boot process, and installation of software needed to support these “hack” sessions.

Android optimizations for ARM by Linaro Engineers
Linaro Engineers present a bunch of optimizations they recently did in Android for ARM. These optimizations are in areas like BIONIC for Cortex C string routines, migrating to GCC 4.9, migrating the external projects to their latest versions, optimizing SQLite, optimizing battery life, also they discuss their progress building Android with CLANG, migrating Android to latest versions and how Linaro is planning to release these optimizations to the Android community through Linaro Android releases and upstream them to respective project repositories.

The Android Linaro team’s presentations are live and available on Linaro.org LCA14 and on youtube at LinaraOnAir channel – http://www.youtube.com/user/LinaroOnAir:
LCA14-205: Optimizing SQLite for Android mobile

Vincent Guittot on the Linaro big.LITTLE MP work
Vincent Guittot, Linaro assignee from ST-Ericsson, talks about the work that is being done at Linaro to Extend the Linux kernel to support ARM’s big.LITTLE MP architecture, building on the features provided by the big.LITTLE Switcher project. The most powerful use model of big.LITTLE is called MP and enables the use of all physical cores at the same time. Threads with high priority and/or computationally intensive can in this case be allocated to the A15 cores while threads with less priority or less computationally intensive such as background tasks can be performed by the A7 cores.
