FOSDEM 2015 Schedule – January 31 – February 1 2015

FOSDEM (Free and Open Source Software Developers’ European Meeting) takes place every year during the first week-end of February. This year the developer-oriented event expects to bring over 5000 geeks to share ideas and collaborate on open source projects. Contrary to most other events, it’s free to attend, and you don’t even need to register, just show up. FOSDEM 2015 will take place on January 31- February 1 in Brussels. There will be 551 sessions divided into 5 keynotes, 40 lightning talks, 6 certification exams, and with the bulk being developer rooms and main tracks, divided into 7 main tracks this year: Languages, Performance, Time, Typesetting, Hardware, Security and Miscellaneous. I’m not going to attend, but it’s still interested to see what will be talked about, and I’ve concocted my own little virtual program out of the main tracks and developers’ rooms. There’s a few minutes overlap between some talks […]

How to Install Ubuntu ARM64 on Nexus 9 Tablet

HTC Nexus 9 is one of the first 64-bit ARM platform with powerful ARMv8 cores (e.g. not Cortex A53) that both commercially available, and relatively affordable at $399 to $599, at least significantly cheaper than the server boards such as Applied Micro X-C1. The tablet comes with Android 5.0 Lollipop, but for those of you who wish to have an ARM64 platform running Ubuntu or other 64-bit Linux operating systems, Ubuntu installation instructions provided by Ryan Houdek, Dolphin emulator developer, might come handy, especially it won’t affect your Android installation provided you have already unlocked your bootloader. The instructions are fairly long so I won’t reproduce them all here, so I recommend you check the detailed instructions on XDA, but the short summary below may give an idea of the amount of work needed: Install dependencies such as Aarch64 toolchain:

sudo apt-get install gcc g++ git gcc-4.9-aarch64-linux-gnu g++-4.9-aarch64-linux-gnu

1	sudo apt-get install gcc g++ git gcc-4.9-aarch64-linux-gnu g++-4.9-aarch64-linux-gnu

Build a initramfs with buildroot. You’ll need to enable […]

TyGL OpenGL ES 2.0 Backend for WebKit Speeds Up Web Rendering by Up to 11 Times

ARM, Szeged University in Hungary, and Samsung Research UK have been working on TyGL, a new backend for WebKit accelerated with OpenGL ES2.0, and developed and tested on ARM Mali-T628 GPU found in Samsung ARM Chromebook. It will typically provide 1.5 to 4.5 times higher performance, but in the best cases, it can achieve up to eleven times the performance of a CPU-only rendered page. The key features of TyGL include: Web rendering accelerated by GPU – Batching of draw calls delivers better results on GPUs. TyGL groups commands together to avoid frequent state changes while calling the Graphics Context API. Automatic shader generation – TyGL generates complex shaders from multiple shader fragments, and ensures the batches fit into the shader cache of the GPU. Trapezoid based path rendering – Work in progress. It will leverage GPU capabilities such as the Pixel Local Storage extension for OpenGL ES. No software […]

AllWinner A80 Linux SDK Released

After Android 4.4 SDK for AllWinner A31 last week, another AllWinner software development kit has been seen in the wild, this time for the new AllWinner A80 octa-core processor. A80 SDK includes source code for the Linux Kernel and U-boot, as well as buildroot, and various AllWinner tools. I’ve also noticed AllWinner A80 datasheet is available, but with the strict minimum information (45 pages). Let’s get the code, and extract it:

wget http://dl.linux-sunxi.org/SDK/A80/A80_SDK_20140728.tar.gz
tar xvf A80_SDK_20140728.tar.gz
cd A80_SDK_20140728

wget http://dl.linux-sunxi.org/SDK/A80/A80_SDK_20140728.tar.gz

tar xvf A80_SDK_20140728.tar.gz

cd A80_SDK_20140728

Now we need to configure the build:

./build.sh config

sun9i is the codename for AllWinner A80, not sure what w1p1 means. Dragonboard must be the internal Allwinner development board, but I just selected Linux, since the SDK does not come with Android, and finally I opted for optimus, which could stand for OptimusBoard. You may need to install extra dependencies in your build machine, for example (in Ubuntu 14.04):

sudo apt-get install flex texinfo build-essential

Now let’s start buildroot which should retrieve the toolchain, […]
