2D/3D Graphics Linux Demo (X11, EGL, GLES2, Qt4) on AllWinner A10 Tablet

Xlab (Maxim Kouprianov) has tested 2D & 3D capabilities of AllWinner A10 SoC (with Mali-400 GPU) on a Ployer MOMO11 Bird Edition tablet running OpenEmbedded with kernel 3.0.52+ testing X11, EGL, OpenGL ES2 and Qt4 on the platform, and the results are pretty smooth as you can see in the video below, although there appears to be some flickering in LunaSysMgr demo. The tools used in the demos are xfwm4 (Xfce Windows Manager), es2gears_x11, cube (Qt), LunaSysMgr (Qt/WebOS) and glmark2-es2. Qt4 acceleration is done via XlibGL platform which in turns uses X11-EGL. He used the Mali drivers version r3p0 (mali400-gles20-gles11-linux-x11-ump) and xf86-video-mali on sunxi-linux github repository mainly maintained by rz2k. You can get more details on how to build Mali-400 support for AllWinner A10 on http://linux-sunxi.org/Mali400, and GPU benchmark results for A10 show the drivers seem to work as expected.

Kimdecent T21 mini PC Unboxing and Review

Androidpc.es has written a review for the low cost ($49) Kimdecent T21 dual core mini PC in Spanish, and I’ll provide a summary of the review in English below. Kimdecent T21 Unboxing Kimdecent T21 is an Android 4.1 HDMI TV Stick powered by Nufront NS115 dual core Cortex A9 processor. Check out my earlier post about Kimdecent T21 for specifications. The package comes with T21 mini PC, a power adapter with USB to micro USB cable, and a user manual in English. You can also watch T21 Unboxing Video on YouTube. Kimdecent T21 User Interface & System Overview The user interface is a standard Android screen, albeit with power and volume buttons in the Status Bar. I don’t really find this interface very suitable for the TV, but you can always install your own launcher such as Android TV Launcher (apk), or other launcher apps available on Google Play. Beside […]

SoC Power Measurement with ARM Energy Probes and Linux EAP Tools

Andy Green, TI Landing Team lead at Linaro, gave an interesting presentation entitled “How to measure SoC power” at Linaro Connect Europe 2012. This talk was specifically aimed at software engineers, so that they know how to properly measure power consumption, and take actions to optimize the software to decrease it. In the first part of the presentation, he gives an overview of electronics basics with definition of voltage, load, current and power, units used for power measurements (Clue: you need to use Watts), and how voltage, current and power can be measured with voltmeters and ammeters. When you want to measure power in a rail, you would usually insert a shun resistor, use a multimeter and derive the power from the resistance and the measured voltage (P=V2/R). He also gives details about regulator efficiency, choosing measurement sampling… There are 4 common measurements strategies: DC IN – Easiest way, gives the complete […]

Xibo for Android on Mele A1000 Set-top Box & WM8850-MID Tablet

Earlier this month, Xibo developers announced the beta version Xibo for Android was available for testing. Contrary to the Linux & Windows clients and servers which are open source, Xibo for Android is developed by Spring Signage and will available commercially. This sponsorship will help finance the development of Xibo open source software: the 2 clients (.net in Windows, Python in Linux), the server and API. The current beta version supports the most important features of the Windows client, but lacks support for Adobe Flash, Microsoft PowerPoint, Datasets, Microblog, Stats, Counter Media, Socket Listener, Lift/Serial Interface Support, Offline Update via USB Drive, Full Compositing (overlapping regions) and Video Transparency. If you want to test the Xibo client for android, you can register for the private BETA and download an APK (Xibo_Android_Clientv1.0.12.apk) to install on your Android devices. Being part of the BETA program will also guarantee you a price of […]
