MQMaker MiQi & ASUS Tinker Boards Get Linux 4.11 with 3D Graphics Acceleration

One day after the release of Linux 4.11, developer “Miouyouyou” has released Linux 4.11 for Rockchip RK3288 platforms such as MQMaker MiQi and ASUS Tinker boards with some patchsets for ARM Mali r16p0 kernel drivers, ARM fbdev, and to improve performance. The kernel has been tested with the Mali User-space r12p0 drivers for fbdev and wayland written for Firefly-RK3288, and some OpenGL ES 3.1/3.2 samples could successfully run on the board. 3D graphics acceleration does not work in X11 however. Miouyouyou also plans to add support for Rockchip VPU code, as well as ARM gator, and document how to use ARM DS-5 Streamline for OpenGL ES 2.x/3.x debugging. If you have a MiQi or Tinker board running Debian, you can try the kernel by adding beta.armbian.com Debian repository to your apt source file, and installing the following packages:

Linux 4.11 Release – Main Changes, ARM & MIPS Architecture

Linus Torvalds has just released Linux 4.11: So after that extra week with an rc8, things were pretty calm, and I’m much happier releasing a final 4.11 now. We still had various smaller fixes the last week, but nothing that made me go “hmm..”. Shortlog appended for people who want to peruse the details, but it’s a mix all over, with about half being drivers (networking dominates, but some sound fixlets too), with the rest being some arch updates, generic networking, and filesystem (nfs[d]) fixes. But it’s all really small, which is what I like to see the last week of the release cycle. And with this, the merge window is obviously open. I already have two pull request for 4.12 in my inbox, I expect that overnight I’ll get a lot more. Linux 4.10 added Virtual GPU support, perf c2c’ tool, improved writeback management, a faster initial WiFi connection […]

Open Source ARM Compute Library Released with NEON and OpenCL Accelerated Functions for Computer Vision, Machine Learning

GPU compute promises to deliver much better performance compared to CPU compute for application such a computer vision and machine learning, but the problem is that many developers may not have the right skills or time to leverage APIs such as OpenCL. So ARM decided to write their own ARM Compute library and has now released it under an MIT license. The functions found in the library include: Basic arithmetic, mathematical, and binary operator functions Color manipulation (conversion, channel extraction, and more) Convolution filters (Sobel, Gaussian, and more) Canny Edge, Harris corners, optical flow, and more Pyramids (such as Laplacians) HOG (Histogram of Oriented Gradients) SVM (Support Vector Machines) H/SGEMM (Half and Single precision General Matrix Multiply) Convolutional Neural Networks building blocks (Activation, Convolution, Fully connected, Locally connected, Normalization, Pooling, Soft-max) The library works on Linux, Android or bare metal on armv7a (32bit) or arm64-v8a (64bit) architecture, and makes use […]

NVIDIA Introduces Jetson TX2 Embedded Artificial Intelligence Computer

NVIDIA has just announced an upgrade to to their Jetson TX1 module, with Jetson TX2 “Embedded AI Computer” with Tegra X2 Parker SoC that either doubles the performance of its predecessor, or runs at more than twice the power efficiency, while drawing less than 7.5 watts of power. The company provided a comparison showing the differences between TX1 and TX2 modules.

Linux 4.10 Release – Main Changes, ARM & MIPS Architectures

Linus Torvalds has just released Linux 4.10: So there it is, the final 4.10 release. It’s been quiet since rc8, but we did end up fixing several small issues, so the extra week was all good. On the whole, 4.10 didn’t end up as small as it initially looked. After the huge release that was 4.9, I expected things to be pretty quiet, but it ended up very much a fairly average release by modern kernel standards. So we have about 13,000 commits (not counting merges – that would be another 1200+ commits if you count those). The work is all over, obviously – the shortlog below is just the changes in the last week, since rc8. Go out and verify that it’s all good, and I’ll obviously start pulling stuff for 4.11 on Monday. Linus Linux 4.9 added Greybus staging support, improved security thanks to virtually mapped kernel stacks, […]

Self-hosted OpenGL ES Development on Ubuntu Touch

Blu wrote BQ Aquaris M10 Ubuntu Edition review – from a developer’s perspective – last year, and now is back with a new post explaining how to develop and deploy OpenGL ES applications directly on the Ubuntu Touch tablet. Ever since I started using a BQ M10 for console apps development on the go I’ve been wanting to get something, well, flashier going on that tablet. Since I’m a graphics developer by trade and by heart, GLES was the next step on the Ubuntu Touch for me. This article is about writing, building and deploying GLES code on Ubuntu Touch itself, sans a desktop PC. Keep that in mind if some procedure seems unrefined or straight primitive to you – for one, I’m a primitive person, but some tools available on the desktop are, in my opinion, impractical on the Touch itself. That means no QtCreator today, nor Qt, for […]

Imagination PowerVR G6230 is the First GPU To Pass Khronos OpenVX 1.1 Conformance

The Khronos Group is the non-profit consortium group behind open standards and APIs for graphics, media and parallel computation such as OpenGL for 3D graphics, OpenCL for GPGPU, OpenVG for 2D vector graphics, etc… OpenVX is one of their most recent open, royalty-free standard, and targets power optimized acceleration of computer vision applications such as face, body and gesture tracking, smart video surveillance, advanced driver assistance systems (ADAS), object and scene reconstruction, augmented reality, visual inspection, robotics and more. The first revision of the standard was released in 2014, and the latest OpenVX 1.1 revision was just released in May 2016. We’ve already seen OpenVX 1.1 support in Nvidia Jetson TX1 module & board, but Khronos has a conformance program to test  implementations, and if successful, allow companies to use the logo and name of the API. The version first GPU to pass OpenVX 1.1 conformance is Imagination Technologies PowerVR […]

ARM Introduces Bifrost Mali-G51 GPU, and Mali-V61 4K H.265 & VP9 Video Processing Unit

Back in May of this year, ARM unveiled Mali-G71 GPU for premium devices, and the first GPU of the company based on Bifrost architecture. The company has now introduced the second Bifrost GPU with Mali-G51 targeting augmented & virtual reality and higher resolution screens to be found in mainstream devices in 2018, as well as Mali-V61 VPU with 4K H.265 & VP9 video decode and encode capabilities, previously unknown under the codename “Egil“. Mali-G51 GPU ARM Mali-G51 will be 60% more energy efficiency, and have 60% more performance density compared to Mali-T830 GPU, making the new GPU the most efficient ARM GPU to date. It will also be 30% smaller, and support 1080p to 4K displays. Under the hood, Mali-G51 include an updated Bifrost’s low level instruction set, a dual-pixel shader core per GPU core to deliver twice the texel and pixel rates, features the latest ARM Frame Buffer Compression […]
