Embedded Linux Conference Europe 2013 Schedule – Build Systems, Security, Device Tree, Debugging & Profiling Techniques, and More

Embedded Linux Conference Europe 2013 will conveniently start right after LinuxCon 2013, last 2 days (October 23-24), and take place at the same location: the Edinburgh International Conference Center, Edinburgh, United Kingdom. The Linux Foundation has published the schedule for the conference, so I’ll make my own virtual schedule with sessions that I find particularly interesting. Thursday – 24th of October 9:30 – 10:10 – Timeline For Embedded Linux by Chris Simmonds, Consultant, 2net Limited Today, Linux is woven into the fabric of our technology. Things such as printers, routers, TVs and phones all have their own “Inner Penguin”. Yet it was never originally intended to be used beyond desktop and server PCs. A lot of things had to happen before Linux could break out of the PC environment and make its way in the world as a jobbing jack-of-all-trades. Since the early beginnings of embedded Linux in the late 1990’s many people have contributed […]

LinuxCon North America 2013 Schedule

LinuxCon (North America) 2013 will take place on September 16 – 18, 2013 in New Orleans, LA. The event will be co-located with several other conferences: the Linux Plumbers Conference, the Xen Project User Summit, the OpenDaylight Mini-Summit, the Gluster Workshop 2013, the UEFI Plugfest, the Linux Wireless Summit, the Linux Security Summit, and CloudOpen 2013. LinuxCon consists of 3 days of keynotes, and legal, operations, and developers related sessions as well as tutorials and workshops. There will be around 150 sessions and keynotes during those 3 days. I’ve gone through developer sessions and selected one for each time period. Monday, September 16 10:35 – 11:25 – UEFI and Linux by Kirk Bresniker, HP UEFI has become ubiquitous on the PC client systems and is coming up on servers and ARM-based systems, it is becoming the converged firmware infrastructure. UEFI Secure Boot feature has attracted a lot of attention from […]

ARM TechCon 2013 Schedule – ARM Servers, Internet of Things, Multicore, Hardware and Software Optimization and More

ARM Technology Conference (TechCon) 2013 will take place on October 29 – 31, 2013, in Santa Clara, and the detailed schedule for the event has just been made available. In the previous years, the conference was divided into  Chip Designs day (1 day), and the other 2 days were reserved for Software & System Design, but this year it does not appear to be the case. Whether you’ll be able to attend the event or not, it’s worth having a look at what will be discussed there in order to have a better understanding of what will be the key ARM developments in the near future in terms of hardware and software. There will be around 90 sessions categorized into 15 tracks: Accelerating Hardware Development – This track explores the resources, tools, and techniques that designers can employ to quickly bring hardware to market. Topics include multicore design, ARM IP, […]

Rockchip SoCs Comparison Table, RK32xx Quad Core Cortex A12 Coming Up in 2014

They guys at Linux Rockchip have setup a comparison table between Rockchip processors, but it’s not quite complete yet, and Rockchip noticed it, so they’ve just sent them the most recent Company Presentation that provides more details, including a roadmap. In this documentation, we can see the company targets different types of products with their SoCs: Android OTT dongle/box (aka mini PC, HDMI TV dongles…) – RK2928, RK3066, RK3068, and RK3188 Tablets – RK2926, RK2928, RK3028, RK3066, RK3168, and RK3188 EPD E-Book – RK2818, RK2906 and RK2918 MP3 player – RKnanoC On page 12 of the presentation, they have a convenient comparison table for the SoC used in mini PCs and Tablets.

big.LITTLE Processing Update – In-Kernel Switcher vs Global Task Scheduling

big.LITTLE processing is a new technology announced by ARM in 2011 that allows an SoC to feature low power cores (e.g. Cortex A7) together with high performance cores (e.g. Cortex A15) in order to optimize power consumption. I’ve previously detailed two big.LITTLE software implementation methods: In-kernel switcher which runs tasks on either Cortex A7 or Cortex A15 depending on the load, but both processors can not run simultaneously. Heterogeneous multiprocessing (now called Global Task Scheduling) that assigns tasks to relevant Cortex A7 or Cortex A15 cores, and if needed, allows all cores to run at the same time. Linaro has just provided a update for the big.LITTLE software implementation. There are currently only two SoCs that ship in products with Linaro b.L kernel support: ARM’s reference Test Chip 2 (TC2) tile for the Versatile Express development platform, configured as an SoC with 2 Cortex-A15 cores and 3 Cortex-A7 cores. Samsung-LSI’s […]

Linaro Connect Europe 2013 Sessions and Mini-Summit

Linaro Connect Europe 2013 (LCE13) is taking place in Dublin, Ireland on July 8 – 12, 2013. If you are not there, you can still follow the event remotely as the event schedule is available with tracks focused on Android, Builds and Baselines, Enterprise, Graphics and Multimedia, Linux Kernel, Network, Project Management Tools and Training, and the Testing and Validation mini-summit will also take place at the same time. There will be hacking and lab sessions each day (except on Friday) where you can expect to learn useful skills. I’ve selected 2 sessions per day that I think might be particularly interesting. Monday 10:00 – 10:45 – ARMv8 Status and Updates Current Status of v8 tree What’s merged? What’s features are next priorities? Platform Updates What members should know about adding new v8 platforms 12:00 – 13:00 – How to make Android more efficient for entry level products The main objective of […]

AMD “Seattle” Server CPU to Pack up to 16 ARM Cortex A57 Cores

AMD has published a roadmap for the rest of 2013 and 2014 for its server processors, and among all the x86 “Jaguar”, “Warsaw” and “Streamroller” CPUs, there’s an “oddity” with the “Seatlle” processor featuring up to 16 ARM Cortex A57 cores using ARMv8 64-Bit architecture. “Seattle” will come with either 8- or 16-core CPU with ARM Cortex-A57 cores clocked at 2GHz or greater, and is expected to offer 2 to 4 times the performance of AMD Opteron X-Series processors (x86 APU SoC) with improvement in compute-per-watt.  “Seatlle” will handle up to 128GB DRAM, use offload engines for better power efficiency and reduced CPU loading, provides server caliber encryption, compression and legacy networking including integrated 10GbE. “Seattle” samples are expected to be available in Q1 2014, with production in H2 2014.

Calxeda Showcases Aaeon and Foxconn ARM Servers at Computex 2013

ARM started to get involved in servers in 2011 with the announcements of Calxeda Energy Core, Marvell, and Applied Micro X-Gene Servers-on-a-Chip, and in 2012, products made by companies such as HP and Mitac  started to appears. We’ve got to see some more ARM based servers this year thanks to Charbax, who filmed some Aaeon and Foxconn servers powered by Calxeda EnergyCore quad core ARM Cortex A9 SoC at Computex 2013. The first server is Aaeon Indus 1U cloud storage appliance: 1U Chassis 2x Calxeda Energycore nodes 10x 3.5″ HDD 2x 10 GbE uplinks and 4x 10GbE chassis-to-chassis interconnects Foxconn server shown at Computex has slightly higher specs: 4U chassis 12 Calxeda Energycore nodes 60x 3.5″ HDD for up to 240TB storage 4x 10 GbE uplinks and 6x 10 GbE chassis-to-chassis interconnects for 100 GbE total bandwidth There’s also a Gigabyte server, but I could get details.
