Graphics: V3D, AMD/Vega, Flicker-Free Boot

Filed under
Graphics/Benchmarks
  • V3D Compute, VC4 display, PM

    For V3D last week, I resurrected my old GLES 3.1 series with SSBO and shader imgae support, rebuilt it for V3D 4.1 (shader images no longer need manual tiling), and wrote indirect draw support and started on compute shaders. As of this weekend, dEQP-GLES31 is passing 1387/1567 of tests with “compute” in the name on the simulator. I have a fix needed for barrier(), then it’s time to build the kernel interface. In the process, I ended up fixing several job flushing bugs, plugging memory leaks, improving our shader disassembly debug dumps, and reducing memory consumption and CPU overhead.

  • AMD Outs New Vega 10 & 20 IDs With Linux Driver Patch

    AMD may have accidentally revealed some new products containing its Radeon RX Vega 10 and Radeon RX Vega 20 graphics technologies. The company patched its RadeonSI Mesa and AMDKFD/AMDGPU kernel drivers with new PCI IDs; no other changes were made with the patch.

    Phoronix reported that the patch added six new IDs released to Vega 10: 0x6869, 0x686A, 0x686B, 0x686D, 0x686E, and 0x686F. These are new IDs that were previously only referenced in an update to macOS Mojave and GPUOpen's lists of GFX9 parts. That could mean AMD plans to introduce new Vega 10 products sooner than later, but the company might also be internally testing new products that are a ways from release.

  • AMD Files Trademark For Vega II

    It looks like AMD could be announcing Vega II as new 7nm Vega GPUs soon complementing the recently announced Vega 20 Radeon Instinct MI50 / MI60 accelerators.

  • Arch Linux Users With Intel Graphics Can Begin Enjoying A Flicker-Free Boot

    It looks like the recent efforts led by Red Hat / Fedora on providing a flicker-free Linux boot experience and thanks to their upstream-focused approach is starting to pay off for the other desktop Linux distributions... A flicker-free boot experience can now be achieved on Arch Linux with the latest packages, assuming you don't have any quirky hardware. 

    A Phoronix reader reported in earlier today that Arch Linux as of the 4.19.8-arch1-1-ARCH kernel is working out well for the seamless/flicker-free boot experience. The caveat though -- like with Fedora -- is that it only works with Intel graphics hardware/driver for now and does require setting the "i915.fastboot=1" kernel module parameter.

KDE4 and Plasma 5 for Slackware

  • KDE4 and Qt4 deprecation in FreeBSD

    This is a reminder — for those who don’t read all of the FreeBSD mailing lists — that KDE4 is marked deprecated in the official ports tree for FreeBSD, and will be removed at the end of this year (in about 20 days). Then Qt4 will be removed from the official ports tree in mid-march.

    Since both pieces of software are end-of-life and unmaintained upstream already for several years, the kde@ team at FreeBSD no longer can maintain them. Recent time-sinks were dealing with OpenSSL 1.1.1, libressl, C++17, .. the code is old, and there’s newer, nicer, better-maintained code available generally by replacing 4 with 5.

  • KDE Plasma 5 for Slackware – end of the year edition

    I just uploaded a whole new batch of packages containing KDE Plasma5 for Slackware. The previous batch, KDE 5_18.10 is already two months old and has some library compatibility issues. The new KDE 5_18.12 for Slackware consists of KDE Frameworks 5.53.0, Plasma 5.14.4 and Applications 18.08.3. All this on top of Qt 5.11.3.
    Compiled on the latest Slackware -current, it’s running smoothly here on my laptop.
    I decided against upgrading to QT 5.12.0. This is a new LTS release, but I will wait for the other distros to find bugs in this new software. Next week, KDE will release KDE Applications 18.12.0 and that too is something I want to check a bit before releasing Slackware packages. Therefore it’s likely that a new batch of packages containing Qt 5.12 and KDE Applications 18.12 will see the light shortly after the New Year.

  • GCC 9 Guts Out The PowerPC SPE Support

    It should come as no surprise since it was deprecated in this year's GCC 8 release, but the PowerPC SPE code has been removed.

    This isn't to be confused with conventional POWER/PowerPC but rather PowerPC SPE that is for the "Signal Processing Engine" on older FreeScale/IBM cores like the e500. It's not all that important these days and doesn't affect newer versions of the 64-bit Power support.

  • LLVM's OpenMP Runtime Picks Up DragonFlyBSD & OpenBSD Support

    Good news for those using the LLVM Clang compiler on OpenBSD or DragonFlyBSD: the OpenMP run-time should now be supported with the latest development code.

  • Nick Cameron: Rust in 2022

    In case you missed it, we released our second edition of Rust this year! An edition is an opportunity to make backwards incompatible changes, but more than that it's an opportunity to bring attention to how programming in Rust has changed. With the 2018 edition out of the door, now is the time to think about the next edition: how do we want programming in Rust in 2022 to be different to programming in Rust today? Once we've worked that out, lets work backwards to what should be done in 2019.

    Without thinking about the details, lets think about the timescale and cadence it gives us. It was three years from Rust 1.0 to Rust 2018 and I expect it will be three years until the next edition. Although I think the edition process went quite well, I think that if we'd planned in advance then it could have gone better. In particular, it felt like there were a lot of late changes which could have happened earlier so that we could get more experience with them. In order to avoid that I propose that we aim to avoid breaking changes and large new features landing after the end of 2020. That gives 2021 for finishing, polishing, and marketing with a release late that year. Working backwards, 2020 should be an 'impl year' - focussing on designing and implementing the things we know we want in place for the 2021 edition. 2019 should be a year to invest while we don't have any release pressure.

    To me, investing means paying down technical debt, looking at our processes, infrastructure, tooling, governance, and overheads to see where we can be more efficient in the long run, and working on 'quality of life' improvements for users, the kind that don't make headlines but will make using Rust a better experience. It's also the time to investigate some high-risk, high-reward ideas that will need years of iteration to be user-ready; 2019 should be an exciting year!

  • A Java Developer Walks Into A Ruby Conference: Charles Nutter’s Open Source Journey

    As a Java developer, Nutter began looking for an existing way to run Ruby within a Java runtime environment, specifically a Java virtual machine (JVM). This would let Ruby programs run on any hardware or software platform supported by a JVM, and would facilitate writing polyglot applications that used some Java and some Ruby, with developers free to choose whichever language was best for a particular task.

  • Gnocchi: A Scalable Time Series Database For Your Metrics with Julien Danjou - Episode 189

    Do you know what your servers are doing? If you have a metrics system in place then the answer should be “yes”. One critical aspect of that platform is the timeseries database that allows you to store, aggregate, analyze, and query the various signals generated by your software and hardware. As the size and complexity of your systems scale, so does the volume of data that you need to manage which can put a strain on your metrics stack. Julien Danjou built Gnocchi during his time on the OpenStack project to provide a time oriented data store that would scale horizontally and still provide fast queries. In this episode he explains how the project got started, how it works, how it compares to the other options on the market, and how you can start using it today to get better visibility into your operations.

  • IoT Gateway uses Ubuntu Core and integrates with AWS IoT Greengrass

    Rigado’s Cascade IoT Gateway running Canonical’s secure operating system Ubuntu Core, has integrated with the newly released Amazon Web Services (AWS) IoT Greengrass features to help give teams an easy-to-use mechanism to get Bluetooth-based data to their cloud applications.

    This new functionality combines the scalability of AWS IoT Greengrass edge computing with the flexibility of Bluetooth connectivity and is provided as part of Rigado’s “edge-as-a-service” Cascade IoT Gateway. The direct connection from the Bluetooth sensor to the cloud is made possible through the integration of AWS IoT Greengrass and Rigado’s Edge Connect on the Cascade gateway. It provides the ability to interact with Bluetooth devices using Rigado REST APIs via AWS Lambda. AWS IoT Greengrass Connectors, a new feature of AWS IoT Greengrass, allows applications to connect to AWS services including Amazon Kinesis Data Firehose, Amazon Simple Notification Service (Amazon SNS), and Amazon CloudWatch. This allows for a full data chain with little to no coding required.

  • Linux networking project: ‘expose & orchestrate’ to ONAP

    LF Networking (LFN) is the label used by the Linux Foundation to denote the coming together of seven top networking projects.

    In other (arguably more straightforward) words, LFN is an open source networking stack.

    The openly stated aim of LFN is to increase harmonisation across platforms, communities and ecosystems.

    This December 2018 sees new platform releases from ONAP (Casablanca) and OPNFV (Gambia) with additional support for cross-stack deployments across use cases such as 5G, Cross-Carrier VPN (CCVPN), as well as enhancements to cloud-native VPN.

    The cloud-computing startup Mesosphere is taking tech conference musical guests to a fun new level by presenting a side event Tuesday night called Ice Cube-Con. A website dedicated to the performance even reads “Straight Outta KubeCon” in a nod to NWA’s 1988 debut album “Straight Outta Compton.”

  • Celebrating K8s crates inflation rate, Linux mates congregate

    A number of open source types are heading toward Seattle, Washington, on Monday, if they're not already installed there, to attend the Cloud Native Computing Foundation's (CNCF) KubeCon + CloudNativeCon North America 2018 confab.

    The forecast for the cloud-centric event is rain, with widespread Kubernetes. The gathering begins Tuesday, not counting preparatory cocktails. Nonetheless, a press release downpour should arrive on Monday in which less consequential announcements get served as hors d'oeuvres.

    Platform9, a managed hybrid cloud service, plans to tout a handful of corporate customers – Aruba Networks, EBSCO, Hewlett Packard Enterprise (HPE), Juniper Networks, and Snapfish – who've started using its managed Kubernetes service. The idea is that if it's good enough for them, it's good enough for you.

  • Introducing the Interactive Deep Learning Landscape

    The artificial intelligence (AI), deep learning (DL) and machine learning (ML) space is changing rapidly, with new projects and companies launching, existing ones growing, expanding and consolidating. More companies are also releasing their internal AI, ML, DL efforts under open source licenses to leverage the power of collaborative development, benefit from the innovation multiplier effect of open source, and provide faster, more agile development and accelerated time to market.

    To make sense of it all and keep up to date on an ongoing basis, the LF Deep Learning Foundation has created an interactive Deep Learning Landscape, based on the Cloud Native Landscape pioneered by CNCF. This landscape is intended as a map to explore open source AI, ML, DL projects. It also showcases the member companies of the LF Deep Learning Foundation who contribute contribute heavily to open source AI, ML and DL and bring in their own projects to be housed at the Foundation.

  • What’s the most secure operating system?

    Linux has a family of different free versions (known as distributions, or distros) to choose from, based on users’ computer skills. If you’re just getting started, check out Mint or Ubuntu. And because Linux is open-source, users can make copies of modified systems and give them away to friends in need.

  • Cryptomining campaign pulls new ‘Linux Rabbit’ malware out of its black hat [Ed: No, it's not ‘Linux Rabbit’ but ‘Weak Password Rabbit’; calling it Linux is rather misleading, distracts from the real problem.]
  • Linux malware: is it so hard to get it right? [Ed: Recognising Catalin Cimpaun for what he really is (and has always been): a clickbaiting troll. For CBS to employ him for ZDNet says a lot about the agenda.]

    Once again, so-called security researchers and tech writers have combined to provide misinformation about trojanised SSH scripts which can be run on a Linux server after said server is compromised through a brute-force attack and root status attained. And they call it Linux malware!
    Security firm ESET and ZDNet writer Catalin Cimpanu have both got it wrong in the past — the latter on numerous occasions as he simply does not seem to understand anything about the Linux security model — but both continue to persist in trying to pursue the topic. ESET has gone in the wrong direction on torrent files and clients too.

    Arguably, there is reason to do so: Linux and malware in the same headline do still serve as some kind of clickbait.

    [...]

    Cimpanu was more descriptive, but again made the same fundamental mistake. Malware can be created for any operating system, but the crucial question is how do you get it onto that system?

    [...]

    Cimpanu's former employer, Bleeping Computer, was also prone to screw-ups of this nature. Here is the editor of Bleeping Computer, Lawrence Abrams, expounding on ransomware targeting Linux servers.

    But then Bleeping Computer is a relatively small operation. One would have thought that ZDNet, which has tons of resources, would have a little more editorial quality control.

GNOME

Now, if you’re a regular reader of this site then may recall our post on a new GNOME icon theme back in July. At the time only a handful of core GNOME apps had been given newly redesigned icons.

Fast forward a season or so and not only is the give-core-apps-new-icons initiative well underway, but the redesign effort has extended to other parts of the desktop experience, including the default theme.

Modernising the look and feel of GNOME apps and the shell is a) a bit overdue and Cool happening as part of a wider update to GNOME design guidelines. The idea is to give the desktop a distinct yet consistent appearance.

    Google+ still hadn’t recovered from the data leak it suffered in October. And now it has to go through the same fortune yet again. The company today announced that a new security loophole found last month can impact 52.5 million users. The data of these users can be taken from the apps that use the API of Google+.

    The data of the 52.5 million users consists of their personal information like name, age, occupation, and email address. Even if the accounts are set on private, developers will be able to access the profile information due to the security bug. Even if the information was set to private, developers had easy access to the data of the users.
