Khadas VIM3L SBC Review with Android 9 Firmware

As you may remember (or not), VIM3L ships either as a bare board pre-loaded with Android 9 or as an HTPC kit with the board running CoreELEC. Read more

Events: Indico, XDC2019 and CCC

  • Testing Indico opensource event management software

    After orgnazing a bunch of conferences in the past years I found some communities had problems choosing a conference management software. One alternative or others had some limitations in one way or another. In the middle I collected a list of opensource alternatives and recently I’m very interested in Indico. This project is created and maintained by the CERN (yes, those guys who invented the WWW too).

  • XDC2020 X.Org/Wayland/Mesa Conference To Be Hosted In Gdansk, Poland

    At the XDC2019 X.Org Developers Conference earlier this month in Montreal they named the location of XDC2020 in Europe. As is their usual rhythm, each XDC they flip between hosting it at a location in the Americas and in Europe. With XDC2019 having been in Canada, for XDC2020 they selected a proposal putting it in Gdansk, Poland. Gdansk is on the Baltic coast and serves as the country's primary seaport. Gdansk has an international airport as well as plenty of railway connections.

  • 36th Chaos Communication Congress to take place in Leipzig

    We would like to fill our approximately 120 curated talk slots with high-quality content and therefore today solicit your submissions with our Call for Participation.

    On four days, in addition to the curated talks in five large halls, there will be a widely varied program of self-organised workshops at the stages of our assemblies distributed throughout the event venue. There will also be lots of art & beauty with exhibitions, light installations, bars and parties.

    We want to stress the unusually short submission deadline this year: 26 October 2019. No excuses, please.

AMD: CPU Microcode, RADV, Blender Foundation and AMDVLK

  • Updated AMD Zen CPU Microcode Lands In Linux-Firmware Tree

    But as is often the case with new additions to linux-firmware.git, the changes to said microcode/firmware binaries aren't usually described in any level of detail. Though with this Zen CPU microcode update it ultimately shouldn't mean too much assuming you are punctual with your motherboard firmware updates that generally ship with the new AMD CPU microcode revisions, in which case the older (in-tree) firmware isn't loaded.

  • RADV Lands More Fixes + Performance Improvements Into Mesa 19.3

    It's always great waking up and to find RADV improvements in Mesa Git for this open-source Radeon Vulkan driver that is particularly popular with Linux gamers. Hitting Mesa 19.3 overnight was re-enabling fast depth/stencil clears with separate aspects for GFX10/Navi. This was disabled before for causing "weird issues" on GFX10 but no longer appears to be the case. This path also works fine when tested with Feral's new Shadow of Mordor Vulkan beta.

  • AMD Joins The Blender Foundation With An Emphasis On Vulkan

    Just earlier this month NVIDIA announced their funding of the Blender Foundation at the flagship "patron" level and now AMD has followed them in backing this foundation for assisting the development of this leading 3D creation software. AMD now joins NVIDIA and Epic Games at the patron level, which means contributing at least €120k per year to the foundation.

  • AMDVLK 2019.Q4.1 Vulkan Driver Brings Performance Tuning, Reworked Pipeline Cache

    AMD has been off their weekly release regiment for their open-source AMDVLK Vulkan driver but this morning they issued their first new release in just about one month. AMDVLK 2019.Q4.1 is this first AMDVLK source drop for the fourth quarter. Given the four weeks since the last Linux Vulkan driver source update, there have been many changes/improvements. Some of the large work items include supporting host mapped foreign memory (VKI_EXT_HOST_MAPPED_FOREIGN_MEMORY), reworking of its Vulkan pipeline cache and other cache improvements, and tuning the shader performance for F1 2017 and The Talos Principle.

SUSE/OpenSUSE: Name Change, YaST, MicroOS and More

  • openSUSE project: vote on name change

    The openSUSE project informed it's members by mail to vote for a potential name change. The vote ends on 07.11.2019 at 23:59 UTC. In a Wiki article the openSUSE Board and Election Committee have gathered the most important arguments for and against a name change for all members.

  • Highlights of YaST Development Sprint 87

    As you may know, we have recently extended YaST to support additional encryption mechanisms like volatile encryption for swap devices or pervasive encryption for data volumes. You can find more details in our blog post titled "Advanced Encryption Options Land in the YaST Partitioner". Those encryption mechanisms offer the possibility of adjusting the sector size of the encryption layer according to the sector size of the disk. That can result in a performance boost with storage devices based on 4k blocks. To get the best of your systems, we have instructed YaST to set the sector size to 4096 bytes whenever is possible, which should improve the performance of the encrypted devices created with the recently implemented methods. Additionally, we took the time to improve the codebase related to encryption, based on the lessons we learned while implementing volatile and pervasive encryption. We also performed some additional tests and we found a problem that we are already fixing in the sprint that has just started.

  • toolbox - bring your own (debugging) utilities with you

    Our Container Host OS openSUSE MicroOS and our Kubernetes platform openSUSE Kubic are both using transactionl-update to apply patches to the system. This implies that a read-only root filesystem is used. While this has big advantages, like it allows to update a cluster automatically in a safe way, this has one drawback: you need to reboot to activate new installed packages. But what if you want to debug a problem and the utility you need is not installed? Who says, that the problem is still debuggable after a reboot?

  • Why software-defined storage is right for the hybrid cloud

    Beyond being an intermediate step, hybrid cloud isn’t particularly well defined. If you took a random selection of three CIOs, they’d each likely explain it differently. It’s a bit like asking three people to imagine a farmyard animal: one thinks “pig”, one thinks “hen” and the other thinks “cow”. All three are right, but all three are imagining something very different. The National Institute of Standards and Technology (NIST) have given us an official hybrid cloud definition but not everyone agrees that this is that helpful. Lauren Nelson, principle analyst at Forrester, described this definition as “far from reality”. We’re at the top of the hype cycle and Nelson was making a fair point: NIST’s definition calls for active bursting from one environment into another, and while most enterprises would see themselves as hybrid, cross environment bursting is in practice nearly as rare as real unicorns.

  • A “Silly Season Blog” – Have Fun with Sapstartsrv and Pacemaker

    This blog is about a funny integration of a plain Linux service into the SAP start framework sapstartsrv and SUSEs High Availability solution based on pacemaker. This solution is not intended to run in productive environments but should demonstrate how to integrate special services.
