Linaro 14.08 Release with Kernel 3.16 and Android 4.4.4

I’m a little late for that one, as Linaro 14.08 was released last Thursday. Nevertheless, this release features Linux kernel 3.16 (baseline), Linux 3.10.52 (LSK), and Android 4.4.4. As usual Linaro has worked on member hardware such as Qualcomm based IFC6410 and ARM Juno &Vexpress boards. They’ve also committed changes for LLVM, big Endian, and added a workload generator tool (rt-app) to the Ubuntu and Android image. This tool has been developed and used by the power management working group, presumably to measure and optimize power consumption under various loads. Here are the highlights of this release: Linux Linaro 3.16-2014.08 GATOR version 5.19 (new version) updated topic from Qualcomm LT (ifc6410 board support) updated Versatile Express ARM64 support (FVP Base and Foundation models, Juno) from ARM LT (Landing Team) updated Versatile Express patches from ARM LT updated LLVM topic (follows the community llvmlinux-latest branch) Big endian support (the 2014.05 topic […]

How to Build and Run Android L 64-bit ARM in QEMU

[Nov, 2014 Update: The method below does not seem to work anymore, but a 64-bit ARM emulator “emulator64-arm64” has now landed in AOSP, and updated instructions are available here]. Most people can’t afford Juno Cortex A57/A53 development board, and mobile processors based on the latest 64-bit ARM cores are only expected by early 2015. But thanks to a small team at Linaro, you can now build and run Android L 64-bit ARM in the latest version of QEMU that supports Aarch64. Alex Bennée, an engineer working for Linaro, wrote a blog post in Linaro’s Core Dump blog explaining the Android emulator is actually based on QEMU, the differences compared to mainline QEMU, the work they’ve done on Android L at Linaro, and most importantly, provided the basic steps showing how to build and try Android L 64-bit ARM (ARMv8) in QEMU. I’ve just done that, but unfortunately, albeit the builds […]

Interview with Allwinner Regarding their Linaro Membership

Since Allwinner has joined the Linaro Digital Home Group earlier this year, many people, including myself, have wondered what it means in terms of Linux support, and the engagement with the open source community. Following up on an idea from a regular reader, I’ve decided to asked a few questions to Ben-El Baz, marketing manager at Allwinner, and Linaro contact for Allwinner, which he kindly answered, and accepted to be published on CNX Software. CNXSoft: Why did Allwinner decide to join Linaro, and especially the Digital Home Group? Allwinner: One of our company’s goals is to be a technology leader. It’s ambitious but not too far-fetched given the background of our leadership and engineering team. There’s an extremely talented group of guys behind the scenes here! Leading is difficult unless you’re involved in collaborative organizations like Linaro that work on new technology. Joining Linaro is an opportunity for us to […]

Linaro 14.07 Release with Linux Kernel 3.16 and Android 4.4

Linaro 14.07 has just been released with Linux Kernel 3.16-rc6 (baseline), Linux Kernel 3.10.50 (LSK), and Android 4.4.4. This month, Linaro has continued development on Juno 64-bit ARM development board, as well as other member boards from Broadcom (Capri), Qualcomm (IFC6410), Hisilicon D01, Samsung (Arndale / Arndale Octa), etc.. Android have been upgraded to version 4.4.4 with images released for Pandaboard, Arndale, Nexus 10, and Nexus 7, built with Linaro GCC 4.9. Here are the highlights of this release: Linux Linaro 3.16-rc6-2014.07 released GATOR version 5.18 (same version as in 2014.04) updated basic Capri board support from Broadcom LT. Good progress in upstreaming the code: now the topic has 21 patch on top of v3.16-rc4 vs 53 patches on top of v3.15 in 2014.06 cycle removed cortex-strings-arm64 topic as the code is accepted into the mainline new topic from Qualcomm LT to add IFC6410 board support updated Versatile Express ARM64 […]

ARM TechCon 2014 Schedule – 64-Bit, IoT, Optimization & Debugging, Security and More

ARM Technology Conference (TechCon) 2014 will take place on October 1 – 3, 2014, in Santa Clara, and as every year, there will be a conference with various sessions for suitable engineers and managers, as well as an exposition where companies showcase their latest ARM based products and solutions. The detailed schedule for the conference has just been made available. Last year, there were 90 sessions organized into 15 tracks, but this year, despite received 300 applications, the organizers decided to scale it down a bit, and there will be 75 session in the following 11 tracks: Chip Implementation Debugging Graphics Heterogeneous Compute New Frontiers Power Efficiency Safety and Security Software Development and Optimization Software Optimization for Infrastructure and Cloud System Design Verification There are also some paid workshops that take all day with topics such as “Android (NDK) and ARM overview”, “ARM and the Internet of Things”, or “ARM […]

Linaro Announces 64-bit ARM Android Port on Juno ARM Development Platform

Last week, Linaro 14.06 was released and one of the highlights was Android booting on ARMv8 models, but the organization has actually ported Android to a new 64-bit ARM platform. Juno ARM Development Platform is actually software development platform for ARMv8-A, including Juno Versatile Express board and an ARMv8-A reference software port developed by Linaro. Juno VExpress Board has the following key hardware features: SoC – 2x ARM Cortex A57 cores @ 1.1 GHz (2MB L2 cache), 4x Cortex A53 cores @ 850 MHz (1MB L2 cache) in big.LITTLE configuration with Mali-T624 GPU @ 600 MHz. Compliant with SBSA specifications Level 1. I/O FPGA – Xilinx SPARTAN-6 MCU – ARM Cortex M3 for Motherboard Configuration Controller (MCC) System Memory – 8GB DDR3L @ 1600 MHz Storage – User and configuration micro SD card lots, 64MB NOR flash, configuration EEPROM Connectivity – 10/100M Ethernet + 10M “configuration” Ethernet Video Output – […]

Prpl Non-Profit Organization to Work on Linux, Android, and OpenWRT for MIPS based Processors

In what looks like an answer, albeit fairly late, to Linaro, the non-profit organization working on open source software for ARM based SoCs, a consortium of companies composed of Imagination Technologies, Broadcom, Cavium, Lantiq, Qualcomm, Ingenic, and a few others, has funded Prpl (pronounced Purple), “an open-source, community-driven, collaborative, non-profit foundation targeting and supporting the MIPS architecture—and open to others—with a focus on enabling next-generation datacenter-to-device portable software and virtualized architectures”. The Prpl foundation will focus on three key objectives: Portability – To create ISA agnostic software for rapid deployment across multiple architecture Virtualization & security – To enable multi-tenant, secure, software, environments in datacenter, networking & storage, home, mobile and embedded Heterogeneous Computing – To leverage compute resources enabling next generation big data analytics and mining Initially there will PEG (Prpl Engineering Group) to take of the following projects for 4 market segments (datacenter, network & storage, connected consumers, […]
