Linux Kernel 3.12 Released

Linus Torvalds has announced the release of Linux Kernel 3.12: I was vacillating whether to do an rc8 or just cut the final 3.12, but since the biggest reason to *not* do a final release was not so much the state of the code, as simply the fact that I’ll be traveling with very bad internet connection next week, I didn’t really want to delay the release. Sure, we had a number of driver reverts, and there was an annoying auto-NUMA memory corruption fix series, but none of it was really worth delaying 3.12 for. But the fact that I’m going to be (effectively) off-line next week means that I’m *not* opening the merge window for 3.13 yet – since I won’t have the bandwidth to really do merges anyway. That doesn’t mean that you can’t send me pull request for the merge window early, of course – maintainers can […]

Linaro 13.08 Release With Linux Kernel 3.11 and Android 4.3

Linaro 13.08 has been released with Linux Kernel 3.11-rc6 (stating), Kernel 3.10.9 (LSK – beta), and Android 4.3. This month is the first release based on Android 4.3, which was only pushed to AOSP at the end of last month. I can also see work on new SoCs/hardware this month with Texas Instruments Keystone II ARM Cortex A15+DSP SoC and Fujitsu AA9 board (Which processor?, I could not find out). A lot of work also appears to have gone in OpenEmbedded, further optimizations have gone into NEON optimized AES encryption in OpenSSL, and more. It’s also the first time I can see a Ubuntu Raring engineering build image for HighBank (Calxeda Energycore). Here are the highlights of this release: Android Engineering Android stack was tuned to achieve 100% CTS pass result on Android 4.3 Analyzing the UEFI EDK II boot loader for Android completed, implementation of fastboot application and USB […]

LinuxCon Europe 2013 Schedule – Web Technologies, Debugging Techniques, Wayland, and More

I’ve just received an email from the Linux Foundation saying the schedule for LinuxCon and CloudOpen Europe 2013 had been made available. The conference will take place for 3 days (October 21-23, 2013) in the Edinburgh International Conference Center, Edinburgh, United Kingdom. There will be over 100 conference sessions, and several co-located events including: Automotive Linux Summit, the Embedded Linux Conference, Gluster Workshop, KVM Forum, Tizen Summit, Xen Project Developer Summit. As I’ve recently done with LinuxCon North America 2013 and ARM TechCon 2013, I’ll make a virtual schedule with selected developer sessions using the event’s schedule builder. You may find out several sessions will also be given in LinuxCon North America. Monday – 21st of October 11:00 – 11:50 – Bluetooth Smart Devices and Low Energy Support on Linux by João Paulo Rechi Vita, INdT This presentation will cover a brief introduction on how the Bluetooth Low Energy technology […]

NVIDIA Releases Source Code, Binaries, and Android Build Instructions for the SHIELD Gaming Console

This morning I’ve read bad news for the open source community. Jean-Baptiste Quéru, leader of the Android Open Source Project (AOSP) has decided to quit the project because AOSP cannot run on the latest Nexus 7 as Qualcomm (lawyers) impeded the project, and Google is unable to released factory images or necessary binary drivers for the GPU. But there’s also good news, as Nvidia has just released source code and binaries to allow developers to fully build an Android image for its SHIELD gaming console. If you want to build an image for the latest image available, following the steps below. Get the code

mkdir ~/shield-open-source
cd ~/shield-open-source
repo init -u git://nv-tegra.nvidia.com/manifest/android/binary.git -b rel-roth-ota-1-partner -m secureos/jb_roth.xml
repo sync -j5

mkdir ~/shield-open-source

cd ~/shield-open-source

repo init -u git://nv-tegra.nvidia.com/manifest/android/binary.git -b rel-roth-ota-1-partner -m secureos/jb_roth.xml

repo sync -j5

Build the Android image (Provided you’ve already setup your Linux PC do build AOSP):

cd ~/shield-open-source
export TOP=`pwd`
cd vendor/nvidia/licensed-binaries
./extract-nv-bins.sh
cd $TOP
. build/envsetup.sh
setpaths
lunch thor-userdebug
mp dev

cd ~/shield-open-source

export TOP=`pwd`

cd vendor/nvidia/licensed-binaries

./extract-nv-bins.sh

cd $TOP

. build/envsetup.sh

setpaths

lunch thor-userdebug

mp dev

Done (mp dev took about one hour for my machine). You should now have the required binary images in out/target/product/roth/ directory. Enter fastboot mode before flashing the binaries by one […]

Linaro 13.07 Release With Linux Kernel 3.10.1 and Android 4.2.2

Linaro 13.07 has been released with Linux Kernel 3.10.1 (both baseline and stable versions), and Android 4.2.2. It’s summer time, so activity seems to have slowdown a bit, yet improvements have done to LAVA with the first LAVA Multi-purpose Prove (LMP) setup, and Linaro has released build with Linux 3.10.1, Ubuntu Raring, OpenEmbedded (ARMv8), and Android. For the very first time, there’s even an Android 4.2.2 community build for HiSilicon K3V2 hardware (HiSilicon Hi4511 development platform). Here are the highlights of this release: LAVA LAVA Core VExpress A9 test images no longer use the master image’s boot loader Support added for interactive bootloader commands. Support for OpenID / Crowd added for LAVA. LAVA Master images updated on images.validation.linaro.org LAVA Multi-node – Multi-Node support has an initial implementation which can support communication between nodes under test via the use of a GroupDispatcher. LAVA Lab Capabilities – LMP (LAVA Multi-purpose Probe) prototypes […]

Hardkernel is Working on ODROID-XU Development Board Based on Exynos 5410 Octa Core Processor

Hardkernel have already done a good job at bringing low cost, high performance development boards based on Exynos 4 Quad processor with boards such as ODROID-X, ODROID-U2, or ODROID-X2. But it appears they are not stopping here, and have recently committed code to support ODROID-XU development board based on Exynos 5410, the 8-core big.LITTLE SoC from Samsung, used in devices such as Galaxy S4. The committed code linked above point the device tree files in arch/arm/boot/dts/ (exynos5410-odroidxu.dts and exynos5410-pinctrl.dtsi) where we can see the board will have 2 GB RAM, and the Cortex A15 cores with be clocked at 1.6 GHz. Exynos5410-odroidxu.dts has been removed from 3.11 branch, so the link above points to an earlier commit. Exynos 5410 might have been the first big.LITTLE processor ever available, but it comes with a major flaw, as it only supports cluster migration (all 4 Cortex A15 or all 4 Cortex A7 […]

Chromecast Open Source Code: Linux Kernel, Toolchain, Bootloader, and More

Google has made quite a stir by introducing Chromecast, and entering the HDMI TV Stick market. We already know the device is based on Marvell 88DE3005 SoC with 512 MB, and since the product are already been shipped to customers in the US, it was just a question of time before the release of the open source code, and everything you need appears to be available at https://code.google.com/p/chromecast-mirrored-source/ Let’s have a look at what we have in the different repositories: Wiki – Empty… Kernel – Linux 3.0.8 source code Prebuilt – Binary toolchain: arm-unknown-linux-gnueabi-4.5.3-glibc Toolchain – Source code for the toolchain above. External – Source code for alsa-libs, dnsmask, libexit and nss sdk – bootloader and DirecFB 1.6.1 vendor – Looks like qt source used in some netflix app (not sure) Chromium – README explaining how you can download Chromecast Chromium source code: 1.8GB tarball + you need to contact […]
