Embedded Linux Conference & Open Source Summit 2019 Schedule

In the last few years, I covered the Embedded Linux Conference and IoT Summit schedules since both were happening at the same time and in the same location. But the Linux Foundation have recently announced the Embedded Linux Conference will combine with the Open Source Summit, so the IoT Summit appears to have been phased out. The full schedule for the events taking place on August 21 – 23, 2019 at the Hilton San Diego Bayfront, USA, has also been released, so I’ll create a virtual schedule with some of the sessions most relevant to this blog. Wednesday August 21, 2019 11:30 – 12:05 – What’s New with U-Boot? by Simon Glass, Google LLC U-Boot is a widely used bootloader in embedded systems. Many users are unaware of the wide feature-set of U-Boot, particularly features added in the last few years. This talk aims to bring users (and prospective users) […]

Panfrost is an Open Source Driver for Arm Mali Midgard GPUs

Getting GPU drivers to work on Linux with Arm SoCs was really a struggle a few years ago due to close-sources binary blobs that required all bugs to be fixed by a single team. But in recent years we’ve seen good progress with open source mobile GPU drivers including Freedreno for Adreno GPUs, and Etnaviv for Vivante GPUs. Arm Mali also got its own open source Lima driver worked on for many years but only for older Utgard GPUs (Mali 400, Mali 450). However, during the Opensource GPU Drivers BoF at Linaro Connect Bangkok 2019, Rob Herring, Technical Architect at Linaro and Tomeu Vizoso, Principal Software Engineer at Collabora, discuss the status of drivers, and I learned about an open source driver for Mali Midgard (Mali-T6xx, Mali-T7xx) GPU called Panfrost. As we’ll see below, the driver is already capable of running basic demos, has been upstreamed to Mesa, and tested […]

ODROID-N2 GPU Drivers, Linux 5.0, and Impressive glmarks-es2 Score

ODROID-N2 was announced last February for $63 (2GB RAM), and $79 (4GB RAM), but Hardkernel was not quite ready to take orders at the time. One of the good news is that the 4GB RAM is now available for pre-order with shipping scheduled to start on April 3. Another good news is on the software side with Hardkernel having released the userland Mali-G52 Wayland driver. It does not work well with Linux 4.9 due to incomplete DRM implementation, but it goes work with Linux 5.0 plus some modifications as further discussed in the aforelinked forum thread. The screenshot above, courtesy of odroid forum member memeka , shows ODROID-N2 running Ubuntu 18.04 + Gnome3 + Linux 5.0 on top of Wayland with GPU drivers providing acceleration as shown by glmark2-es2-wayland test program. The benchmark results are pretty impressive:

Turnip is an Open Source Vulkan Driver for Adreno GPU

Qualcomm Adreno GPUs have one of the best open source GPU driver for Arm SoC thanks to Freedreno driver. The driver relies on OpenGL ES API however, and nearly four of years ago, Khronos introduced the Vulkan API that aims to reduce CPU resources usage, and adds support multiple command buffers. The good news is there has been development of a Vulkan driver for Adreno 500 and 600 series GPU called Turnip, also referred to as Freedreno_vk (Freedreno Vulkan) in the code. The Turnip driver has been developed by Bas Nieuwenhuizen, a Site Reliability Engineer at Google who also happens to be RADV (Radeon Vulkan) lead developer, Chia-I Wu, a Google software engineer working on Android graphics, Chad Versace, Intel’s software engineer working on Linux OpenGL stack, and others as revealed by a recent merge into Mesa 19.1 slated to be released next quarter. Via Phoronix Jean-Luc Aufranc (CNXSoft)Jean-Luc started […]

Linux 4.20 Release – Main Changes, Arm and MIPS Architectures

After Greg K-H handling Linux 4.19 release, Linus Torvalds is back at the helm, and released Linux 4.20 just before Christmas: Let’s face it, last week wasn’t quite as quiet as I would have hoped for, but there really doesn’t seem to be any point to delay 4.20 because everybody is already taking a break. And it’s not like there are any known issues, it’s just that the shortlog below is a bit longer than I would have wished for. Nothing screams “oh, that’s scary”, though. And as part of the “everybody is already taking a break”, I can happily report that I already have quite a few early pull requests in my inbox. I encouraged people to get it over and done with, so that people can just relax over the year-end holidays. In fact, I probably won’t start pulling for a couple of days, but otherwise let’s just […]

Embedded Linux Conference Europe & OpenIoT Summit Europe 2018 Schedule

Embedded Linux Conference OpenIOT Summit Europe 2018

The Embedded Linux Conference & OpenIoT Summit 2018 took place in March of this year in the US, but the European version of the events are now planned to take place on October 21-24 in Edinburg, UK, and the schedule has already been released. So let’s make a virtual schedule to find out more about some of interesting subjects that are covered at the conferences. The conference and summit really only officially start on Monday 22, but there are a few talks on Sunday afternoon too. Sunday, October 21 13:30 – 15:15 – Tutorial: Introduction to Quantum Computing Using Qiskit – Ali Javadi-Abhari, IBM Qiskit is a comprehensive open-source tool for quantum computation. From simple demonstrations of quantum mechanical effects to complicated algorithms for solving problems in AI and chemistry, Qiskit allows users to build and run programs on quantum computers of today. Qiskit is built with modularity and extensibility […]

ROC-RK3328-CC Board Review, or the Case for Fast Storage and Adequate Power Supply

Firefly team from T-chip company has send me some of their Rockchip development boards, and we’ve already checked the provided boards and accessories, so today I’ll report my experience with one of the board: ROC-RK3328-CC also known as Renegade. I won’t test it with Android, since I have already reviewed RK3328 Android TV boxes such as Zidoo X7, and I’ve been told the team is hard at work with Android 8.1 SDK, so an Oreo image should be released in a few weeks/months. So I had initially planned to report my experience with one of the Linux images, then show how to install mainline Linux (currently 4.17) to the board, and reports what works. However, I encountered many issues, although likely not directly related to the board or its software support, so instead I’ll write about my experience getting started with the board, and list all the issues I had […]

Arm Announces Cortex-A76 CPU with Laptop-class Performance, Mali-G76 GPU, Mali-V76 8K VPU

Arm Cortex A75 based processors are only found in a few SoCs and devices, but Arm keeps on innovating, and they’ve now announced a new suite of of IP with Cortex-A76 CPU enabling 35 percent more performance, and Mali-G76 GPU with ML support and 30 percent higher efficiency and performance. SoC based on those new CPU and GPU IP will provide “laptop-class” performance, and the company also announced Arm Mali-V76 VPU with support for 8K video decoding and encoding. Arm Cortex A76 After Cortex A75, the Arm Cortex-A76 CPU is the second high performance processor core based on DynamIQ technology, and beside the 35 percent performance gain mentioned in the introduction, it also offers 40 percent improved efficiency, as well as delivers 4x compute performance improvements for AI/ML at the edge. Highlights of Cortex A76: Architecture – Armv8-A (Harvard) with Armv8.1, Armv8.2, Armv8.3 (LDAPR instructions only), cryptography and RAS extensions […]
