Early Benchmarks Of The Linux 4.9 DRM-Next Radeon/AMDGPU Drivers

Filed under
Graphics/Benchmarks

While Linux 4.9 will not officially open for development until next week, the DRM-Next code is ready to roll with all major feature work having been committed by the different open-source Direct Rendering Manager drivers. In this article is some preliminary testing of this DRM-Next code as of 29 September when testing various AMD GPUs with the Radeon and AMDGPU DRM drivers.

Linux 4.9 does bring compile-time-offered experimental support for the AMD Southern Islands GCN 1.0 hardware on AMDGPU, but that isn't the focus of this article. A follow-up comparison is being done with GCN 1.0/1.1 experimental support enabled to see the Radeon vs. AMDGPU performance difference on that hardware. For today's testing was a Radeon R7 370 to look at the Radeon DRM performance and for AMDGPU testing was the Radeon R9 285, R9 Fury, and RX 480. Benchmarks were done from the Linux 4.8 Git and Linux DRM-Next kernels as of 29 September.

How to Effectively and Efficiently Edit Configuration Files in Linux

Filed under
Linux
HowTos

Every Linux administrator has to eventually (and manually) edit a configuration file. Whether you are setting up a web server, configuring a service to connect to a database, tweaking a bash script, or troubleshooting a network connection, you cannot avoid a dive deep into the heart of one or more configuration files. To some, the prospect of manually editing configuration files is akin to a nightmare. Wading through what seems like countless lines of options and comments can put you on the fast track for hair and sanity loss.

Which, of course, isn’t true. In fact, most Linux administrators enjoy a good debugging or configuration challenge. Sifting through the minutiae of how a server or software functions is a great way to pass time. But this process doesn’t have to be an exercise in ineffective inefficiency. In fact, tools are available to you that go a very long way to make the editing of config files much, much easier. I’m going to introduce you to a few such tools, to ease some of the burden of your Linux admin duties. I’ll first discuss the command-line tools that are invaluable to the task of making configuration more efficient.

Why Good Linux Sysadmins Use Markdown

Filed under
Linux

The Markdown markup language is perfect for writing system administrator documentation: it is lightweight, versatile, and easy to learn, so you spend your time writing instead of fighting with formatting.

The life of a Linux system administrator is complex and varied, and you know that documenting your work is a big time-saver. A documentation web server shared by you and your colleagues is a wonderful productivity tool. Most of us know simple HTML, and can whack up a web page as easily as writing plain text. But using Markdown is better.

  • Tech, talent and tools: The secret to monetizing open-source

    “In California during the gold rush, you didn’t make money digging for gold; you made money selling shovels,” said Mehta. A fitting metaphor for the idea that investing in talent and tools, especially tools, is how to turn a profit. The actual data, databases, algorithms and so on would be open source. Money would come from the tools to use that technology to benefit specific areas, such as automation of healthcare.

    And healthcare is a good place to start. “Big Data is all about making life cheaper, better. … If we forget about how to solve problems for humans, we’ve lost. We want to be known for enriching life,” said Mehta.

  • Changing the way we design for the web

    On the one hand, open source should mean lower cost of entry for people from poorer communities (like me, growing up). But on the other, I feel it is hard to contribute when under- or unemployed. I had a grant to work on the Web Animations API documentation, but I can't do as much as I'd like with other animation features (motion paths, advanced timing functions) because I need to spend a lot of time working on my own business, getting paid.

    Essentially this leads to an awkward model where the only contributors are employed programmers—and when it comes to open source animation or design APIs, platforms, etc, this lack of user input really starts to show. Or, the only products with thriving open source development teams are those that have financially lucrative futures, turning the open source software (OSS) model into a capitalist one.

  • CloudReady by neverware

    I thought I would put together a quick “installation” review of a product called CloudReady by neverware. What is CloudReady? CloudReady is basically a project to bring Chromium OS to those who would like to convert traditional laptops into Chromebook-like devices. I stumbled on them several months ago and finally decided to see how hard it was to install Chromium OS and how functional it actually was as a Chromebook-like device. I have a few low end (netbook-like) devices and I have been trying to figure out how I could make them functional for my boys, I thought this might be the solution.

  • Mozilla tells Firefox OS devs to fork off if they want to chase open web apps vision

    The Mozilla Foundation's Firefox development team has decided enough is enough and will stop supporting Windows XP and Vista in March 2017 and also bin Firefox OS.

    The OS first. In this post Mozillans Ari Jaaksi and David Bryant, respectively the head of connected devices and veep for platform engineering, write that “By the end of 2015 Mozilla leadership had come to the conclusion that our then Firefox OS initiative of shipping phones with commercial partners would not bring Mozilla the returns we sought.”

    That decision means that “as of the end of July 2016 have stopped all commercial development on Firefox OS.”

  • Cloudera Delivers Release Built on Apache Spark 2.0, and Advances Kudu

    Cloudera, focused on Apache Hadoop and other open source technologies,has announced its release built on the Apache Spark 2.0 (Beta), with enhancements to the API experience, performance improvements, and enhanced machine learning capabilities.

    The company is also working with the community to continue developing Apache Kudu 1.0, recently released by the Apache Software Foundation, which we covered here. Kudu is an open source columnar storage engine built for the Apache Hadoop ecosystem designed to enable flexible, high-performance analytic pipelines. Taken together, Cloudera's new tools are giving it more diverse kinds of presence on the Big Data scene.

    Cloudera claims it was the first Hadoop big data analytics vendor to deliver a commercially supported version of Spark, and has participated actively in the open source community to enhance Spark for the enterprise through its One Platform Initiative. "With Spark 2.0, organizations are better able to take advantage of streaming data, develop richer machine learning models, and deploy them in real time, enabling more workloads to go into production," the company reports.

  • Machine Learning with Python

    I first heard the term “machine learning” a few years ago, and to be honest, I basically ignored it that time. I knew that it was a powerful technique, and I knew that it was in vogue, but I didn’t know what it really was— what problems it was designed to solve, how it solved them and how it related to the other sorts of issues I was working on in my professional (consulting) life and in my graduate-school research.

    But in the past few years, machine learning has become a topic that most will avoid at their professional peril. Despite the scary-sounding name, the ideas behind machine learning aren’t that difficult to understand. Moreover, a great deal of open-source software makes it possible for anyone to use machine learning in their own work or research. I don’t think it’s an overstatement to say that machine learning already is having a huge impact on the computer industry and on our day-to-day lives.

  • Linux 5.9 Dropping The Unicore 32-bit RISC Architecture

    It's arguably long overdue but with the just-opened Linux 5.9 kernel cycle the Unicore32 CPU architecture is being removed. Unicore is a 32-bit RISC architecture developed at China's Peking University. Unicore is an ARM-like architecture. But with Unicore not being too popular and this code not seeing any maintenance for the mainline kernel paired with no upstream compiler support, it's time to gut the code out of the kernel.

  • IO_uring Has Many Improvements Set To Go Into Linux 5.9

    Facebook's Jens Axboe who oversees the Linux storage/block code and leads the IO_uring efforts summed up the changes for Linux 5.9 as "hardening the code and/or making it easier to read and fixing [bits]." There is though a big change and that is proper async buffered reads support. That work was previously covered but didn't end up getting pulled into Linux 5.8 due to a branching difference but is now ready to go with Linux 5.9. The async buffered reads support for IO_uring has some nice performance advantages and lower CPU usage while also working its way off KThreads for the fast code path once the async buffered write support is in place.

  • Looks like the recent upwards trend of the Linux market share has calmed down [Ed: As if a Microsoft partner which pretends Android and ChromeOS etc. don't exist was ever painting an accurate picture...]

    For NetMarketShare, something pretty big happened over the last few months. Back in March the Linux share they recorded was only 1.36%, and then it quickly rocketed upwards to 3.61% in June after multiple months of rising. The kind of rise you can't easily just write-off since it continued happening. No one really knows what caused it, possibly a ton more people working from home and not attached to their corporate Windows workstation. Now though, it seems to be levelling out as July's figure now shows it as 3.57%. Considering more people are being told to go back to work, perhaps it was as a result of COVID19. Across that whole time though, it's worth noting StatCounter which also tracks it has hardly moved this whole time. So you may want to press X to doubt on it.

  • Librem 5 June 2020 Software Development Update

    This is another incarnation of the software development progress for the Librem 5. This time for June 2020 (weeks 23-26). Some items are covered in more detail in separate blog posts at https://puri.sm/news. The idea of this summary is to have a closer look at the coding and design side of things. It also shows how much we’re standing on the shoulders of giants reusing existing software and how contributions are flowing back and forth between upstream and downstream projects. This quickly gets interesting since we’re upstream for some projects (e.g. calls, phosh, chatty) and downstream for others (e.g Debian, Linux kernel, GNOME). So these reports are usually rather link heavy pointing to individual merge requests on https://source.puri.sm/ or to the upstream side (like e.g. GNOME’s gitlab).

  • Red Hat certification remote exams now available

    It’s not a new idea that organizations worldwide need and seek qualified IT professionals with the skills and knowledge needed to use Red Hat products successfully. And for the last two decades, Red Hat Training and Certification has provided a way for them to assess, train and validate skills. Last year, we launched preliminary exams as a way to provide experience with our hands-on approach to testing to a broader audience and to explore making this approach more widely available as online exams. This year, the COVID-19 pandemic has meant temporary site closures, lockdowns and social distancing. Going to a test center to take an exam is not an option in many places. Even if it is, candidates for certification might be understandably reluctant to visit a center to take an exam. With that in mind, Red Hat has accelerated our efforts, and I am very pleased to announce that several of our certification exams are now available remotely.

    Condis Supermarcats is a family-owned supermarket chain that is a household name in central and northern Spain. The company operates more than 400 physical storefronts, ranging from hypermarkets to local convenience stores, and a growing digital business. In 2017, Condis began several high-profile projects as part of its digital transformation efforts, including launch of a new customer resource management (CRM) system and a customer-facing mobile application. To support these projects, Condis’s IT team sought to better integrate the company’s IT infrastructure with microservices. "Our architecture was not cloud-integrated or suited for the agile approach we needed to develop our digital business," said Sergio Murillo, Technology Development and IT Operations Manager at Condis. "For example, each Condis store has access to a customer database, centralized using a cloud-based tool. However, we needed this data exchange to be integrated seamlessly with our CRM."
