Nvidia Updates its Tegra Roadmap with Parker 64-Bit ARM SoC, Unveils Kayla CUDA Development Platform

Nvidia has given an update about the roadmap for its Tegra processor at the GPU Technology Conference in San Jose, California. Tegra 4 will still be followed by Logan (Tegra 5) as planned with a Kepler GPU and support for CUDA and OpenGL 4.3, but “Stark” has been replaced by “Parker” (Tegra 6) which will be the first 64-Bit Tegra processor based on Denver CPU, Maxwell GPU and make use of Finfet transistors. Logan will be available in 2014, and Parker should be available in 2015 with 100 times more performance than Tegra 2. With this kind of performance, the separation line between desktop and mobile processors will be gone. Nvidia also unveiled Kayla (“Logan’s girlfriend”), a development platform for CUDA and OpenGL based on Tegra 3 quad-core ARM processor and a Kepler GPU connected via a PCI express slot. Jen-Hsun Huang (above) showcased Kayla performance by running real-time ray […]

FXI Technologies Cotton Candy HDMI Stick To Fully Support Both Android and Ubuntu

FXI Technologies was the first company to ever show an HDMI TV dongle when they unveiled the Cotton Candy in November 2011. Since then, many Chinese companies started to provide similar products at lower cost, and the company further improved the Cotton Candy, which is still powered by Exynos 4210 (dual core Cortex A9), by making it even smaller, and getting rid of the internal flash in the process. As a memory refresher, here are the specifications of the Cotton Candy: SoC – Samsung Exynos 4210 dual core Cortex A9 + Mali-400MP4 System Memory – 1GB DRAM Storage – No flash, up to 64GB microSD Video Output – HDMI Connectibity Wifi 802.11b/g/n Bluetooth 2.1 + EDR USB – USB 2.0 male connector for power and connection to devices that supports USB mass storage + microUSB Video Codecs- 480p/720p/1080p Decode of MPEG4-SP/H.263/H.264 AVC/MPEG-2/VC1 Audio Codecs – MP3, AAC, AAC+, Real Audio […]

Ubuntu 11.10 on GK802/Hi802 mini PC with 2D/3D and Video Hardware Acceleration

You may remember an Ubuntu 11.10 image was released via Geekbuying early January, but this image would not boot on my Hi802, lacked 2D/3D acceleration, and to my knowledge there hasn’t been any update since then. So hope of proper Linux support on the device was fading, until the community discovered Freescale released patches for i.mx6 HDMI dongles, developers setup the imx6-dongle community, and after a lot of work, mainly by three members: Jasbir, Dmitriy (rz2k) and James, there’s now GPU and VPU support on Ubuntu 11.10. Here’s a summary of the current status: Wifi working. External SD working Matched IOMUX configuration to align with the Android image. Stripped out unnecessary device initialisation from the original HDMI dongle source. Enabled EGL and GLES HW Acceleration in Ubuntu. Unity desktop might be partially HW accelerated (TBC) Jasbir uploaded a video to YouTube to show the progress, and it looks pretty good. […]

Renesas Unveils APE6 Octo Core big.LITTLE Processor

Samsung Exynos 5 Octa processor is getting some competition with the announcement of Renesas AP6 processor at MWC2013. This SoC comes with the same big.LITTLE configuration (4x Cortex A15, 4x Cortex A7), but with a PowerVR SGX Series 6 ‘Rogue’ GPU, which, I assume, should outperform PowerVR SGX544MP3 GPU used in Samsung SoC. R-Mobile APE6 could be the fastest mobile processor announced to date, and is currently showcased at Imagination Technologies booth at MWC 2013 running several OpenGL ES 3.0 applications, as well as a demonstration of Rightware’s Kanzi Studio, “a PC-based real-time WYSIWYG editor for designers and embedded engineers to create and customize embedded 3D user interface”. There’s very little information about the processor, so that’s basically all I have for now. But before I conclude, I’ll just drop a performance comparison chart between different PowerVR SGX series (source), since it’s the first mobile processor that I know of […]

Ubuntu Linaro 12.11 with 2D/3D Mali-400 GPU Acceleration on ODROID-X Development Board

A few days ago, Hardkernel released the first version of Ubuntu 12.11 (Linaro) with Mali-400 GPU support for their ODROID boards (ODROID-X/X2, ODROID-U/U2). This is still WIP (Work in Progress), but this is one of the few boards together with Pandaboard, Origen and Snowball that can support 2D/3D GPU acceleration in Ubuntu Quantal. Since I have an ODROID-X development board, I decided to give it a try. There are different ways to install it. I chose the way that is most convenient for me (LCD display instead of HDMI), and likely to yield more performance (eMMC instead of SD Card). The current installation instructions to eMMC are extremely cumbersome and you have to go through 5 main steps: Install Android (yes, seriously) in the eMMC Install Ubuntu in the SD Card Install Ubuntu to the eMMC Upgrade Ubuntu to the latest version Install the Mali drivers In this post I’m […]

Open ARM GPU Drivers FOSDEM 2013 Video and Call to ARM Management

As I previously wrote, FOSDEM organizers are slowly uploading FOSDEM 2013 videos. One of the most interesting talk “Open ARM GPU Drivers” is now available. I’ve also uploaded it to YouTube (embedded below) to give it more exposure. Luc Verhaegen has also written a recent blog post entitled “Hey ARM!” where he announces the release of the modified source for Quake 3 Arena demo, and asks ARM to join them in making an open source driver. Open ARM GPU Drivers @ FOSDEM2013 This session covers the following key points: Problem – Binary drivers are mainly designed to run in Android, and it’s very difficult to have proper GPU drivers for Linux, and companies are not interested to release open source drivers or even just documentation, as they are not convinced it will benefit them in any way. Legal – This is actually the main issue, as open sourcing existing driver […]

Quake 3 Arena Demo Using Lima Driver is (Slightly) Faster than Mali-400 Binary Driver

As mentioned previously, Luc Verhaegen was to give a talk about the status of Lima driver (reverse-engineered Mali-200/400 GPU driver), as well as other GPU open source implementation, at FOSDEM 2013. This is now done, and part of the talk included a demo of Quake 3 Arena (q3a timedemo) running on tablet featuring AllWinner A10 SoC (Cortex A8 @ 1Ghz, Mali-400MP1 GPU @ 320 Mhz, and DDR3 memory @ 360MHz), and a 1024×600 LCD. The fact it works is already a great achievement in itself, but this demo runs at 47.2fps with Lima driver (limare), whereas it can be rendered at 46.2fps using the binary driver. In his blog, Luc also explains that apart from being 2% faster, it also uses 3% less cpu than the binary driver! Take that binary blobs! There’s still more work to do however, as this Quake 3 Arena port is not playable yet for 2 […]

A Selection of FOSDEM 2013 Events

FOSDEM is a 2-day (or 3 if you include Friday beer event) event where over 5,000 members of open source communities meet, share ideas and collaborate. It’s free to attend, and there’s no registration, so you just show up to attend. FOSDEM 2013 takes place on Feb 2-3 (yep, this week-end) in Brussels There are 7 main tracks where sessions are organized: Operating systems Open source challenges Security Janson Beyond operating systems Web development Miscellaneous Robotics There are also keynotes and devroom for a total of 488 sessions. Developers rooms that may particularly be of interest to readers of this blog are: Cross Desktop devroom – e.g. Wayland, gstreamer, razor-qt, Qt Project, Plasma Active, etc… Cross Distro devroom – e.g. Linux on Android, suse on ARM, ARMv8, systemd, etc… Embedded and mobile devroom – e.g. Baserock Embedded Linux, Guacamayo (Yocto), Nemo Mobile/ Mer project, arduino… All in all that’s a […]
