Bernhard Rosenkränzer talks Android speed-up at Linaro

Posted by – April 21, 2014

Linaro Android optimizations gets upstreamed to the main Android releases, here demonstrating Linaro’s latest optimizations to Android to likely be used in the next version of Android be it 4.5 or 5.0. As Google ads all the optimizations from Linaro to the main Android releases, Linaro gets to then focus on something else that still needs optimization for all ARM Android devices to work best.

Arnd Bergmann explains how platform maintainers create git pull requests and how the arm-soc team merges those requests into the arm-soc tree. In this video, Arnd walks Matt Porter through creation and posting of a pull request for the mach-bcm/ platform. Arnd then demonstrates how the branch is merged into the publish arm-soc next branches.

Linaro Security Working Group discussing open source TEE

Posted by – March 19, 2014

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

Posted by – March 18, 2014

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

Posted by – March 15, 2014

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

Posted by – March 15, 2014

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.

Ongoing activity on the Energy Aware Scheduler

Posted by – March 14, 2014

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.
