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.

ARM Cortex-M for Wearables and IoT

Posted by – March 16, 2014

ARM Cortex-M Marketing Manager Diya Soubra talks Wearables and Internet of Things using ARM Cortex-M processor family. The ARM Cortex-M is a group of 32-bit ARM processor cores intended for microcontroller use, consists of the Cortex-M0, Cortex-M0+, Cortex-M1, Cortex-M3, Cortex-M4. The ARM Cortex-M processor family is an upwards compatible range of energy-efficient, easy to use processors designed to help developers meet the needs of tomorrow’s embedded applications. Those demands include delivering more features at a lower cost, increasing connectivity, better code reuse and improved energy efficiency. The Cortex-M family is optimized for cost and power sensitive MCU and mixed-signal devices for end applications such as smart metering, human interface devices, automotive and industrial control systems, white goods, consumer products and medical instrumentation. ARM Cortex-M processors is a global microcontroller standard, having been licensed to over 40 ARM partners including leading vendors such as Freescale, NXP Semiconductors, STMicroelectronics, Texas Instruments, and Toshiba. Using a standard processor allows ARM partners to create devices with a consistent architecture while enabling them to focus on creating superior device implementations.

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.

Linaro engineers implementing ACPI for ARMv8

Posted by – March 13, 2014

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.
