Ubuntu

With hitting the home stretch to Ubuntu 18.10, I've started with my usual benchmark process for checking out this next Ubuntu Linux release dubbed the Cosmic Cuttlefish. Yesterday were Ubuntu 18.10 benchmarks on seven desktop systems from Intel and AMD while next on my agenda has been checking out the server performance. Here's the first of those server tests on Ubuntu 18.10 with some initial AMD EPYC and Intel Xeon Gold tests.

A Quick Test Of NVIDIA's "Carmel" CPU Performance

Filed under
Graphics/Benchmarks

NVIDIA's Tegra Xavier SoC is becoming more widely available now that the Jetson Xavier Development Kit has begun shipping. Besides this latest SoC being an exciting design with its Volta-based GPU and having a Tensor Processing Unit / Deep Learning Accelerator, it's exciting on the CPU side as well with NVIDIA's custom-designed ARMv8 "Carmel" CPU cores.

The Tegra194 (Xavier) SoC features eight 10-wide superscalar Carmel CPU cores that are based on the ARMv8.2-A architecture and manufactured on a TSMC 12nm FinFET process.

Wayland future and legacy

KDE

First I directly admit on what I did teaser for 5.14 in my last update but what will not make it: generic gamma color correction per display. There are two reasons for it. The first one is that some preliminary patches, which needed to be merged first, endured long review phases. The second reason is, that when these patches finally were accepted I had shifted my focus on some other topics, which I decided to give an higher priority.

Before delving into these other topics, a short analysis on why the reviews took so long: first there were of course some improvements possible to my patches, but after these got pointed out in the reviews I did fix them back then pretty quickly. The more striking reason is though that we are just short on people who can actually review KWin code changes, in particular with Martin being not maintainer anymore. That is not only a problem for my proposed code changes, but for anyone’s patches to KWin. And this hasn’t improved since back then. We must find a way to reduce the review pressure on the people being capable of doing reviews somehow, at best with only a minimal hit in code quality. I don’t have a full solution for this problem yet, we will see if we find a good one.

After this is out of the way, let us talk about these other features, which I prioritized higher.

  • Vulkan Adopts A Code Of Conduct [Ed: New way for Khronos Group to control the private lives of developers and get rid of people whom it doesn't like for nontechnical reasons]

    The latest open-source project now officially adopting a Code of Conduct is Vulkan.

    Added today to the Vulkan documentation repository is a Code of Conduct file for Vulkan.

    That Code of Conduct is referencing the main Khronos Group Contributor Code of Conduct.

  • mesa 18.1.9

    Hi List,

    Due to me just forgetting to send out the release on Friday Confused, it's one work day late. Mesa 18.1.9 is now available for general consumption, it is the last release in the 18.1.x series, consider upgrading to 18.2.x for further updates.

    This has been another busy cycle, with roughly 35 real patches (excluding maintainer patches). We've seen long standing bugs in util code fixed, patches to anv and radv, as well as fixes to the android build system, and a few patches here and there across the rest of the code.

    Now that 18.1.x is all wrapped up, I'd like to say I've appreciated working with y'all as the maintainer for this cycle, thank you for your patience as I tried to get the process figured out.

    Dylan

  • Mesa 18.1.9 Released As The Last Of The Series

    Mesa 18.1.9 is now available as the last planned point release of last quarter's release stream.

    With Mesa 18.2.1 having been released, users are encouraged to upgrade to the stable Mesa 18.2 series. But if you're holding off on upgrading for one reason or another, Mesa 18.1.9 is one last push for bug fixes.

  • Wayland's Weston Will Now Respect Your VR HMD

    Wayland's Weston compositor will no longer try to takeover your virtual reality (VR) head-mounted display.

    As was the case too with the X.Org Server up until some months back, Wayland's Weston compositor currently would try to take over VR HMDs like the HTC Vive as just another monitor output... But thanks to the work led by Keith Packard under contract for Valve to improve the X.Org and DRM components for better SteamVR handling on Linux, there is now the non-desktop bit plumbed through the Linux kernel's DRM infrastructure so VR HMDs will be treated as non-desktop display outputs. So user-space finally can know if a display output isn't intended as just another desktop display but for a special use-case like virtual reality.

Ubuntu 18.10 Performance Is Looking Up, But Clear Linux Still Leads In Many Tests

Ubuntu

With less than one month until Ubuntu 18.10 "Cosmic Cuttlefish" releases, I have begun my usual benchmarking dance in checking out how the Ubuntu performance is looking to its current release, in this case the Ubuntu 18.04 LTS "Bionic Beaver". Our first performance look at Ubuntu 18.10 is with a mix of seven Intel and AMD desktop systems while using Ubuntu 18.04 LTS with all updates, Ubuntu 18.10 in its current near-final form, and using Intel's Clear Linux as a gold standard reference with it generally offering the leading out-of-the-box Linux x86_64 performance of major distributions.

Folding@Home Performance Is Looking Good On The GeForce RTX 2080 Ti

Filed under
Graphics/Benchmarks

Yesterday I published a number of CUDA and OpenCL benchmarks for the NVIDIA GeForce RTX 2080 Ti graphics card that happened to show the very strong GPU compote potential for this new Turing GPU. Another workload with promising potential for this powerful but pricey graphics card is Folding@Home.

Folding@Home was accidentally left out of yesterday's RTX 2080 Ti CUDA/OpenCL comparison with simply forgetting to add the FAHBench test profile to the run queue. But as there is often interest in seeing the FAHBench performance on new GPUs by at least a few of the premium enablers, I ran some extra tests just looking at the Folding@Home performance and here are those results today.

  • In-Progress AMDGPU Updates For Linux 4.20~5.0 Have DC Update, New Polaris ID

    -
    Last week AMD sent in their big feature pull request of AMDGPU driver changes to DRM-Next for the Linux 4.20 (or what will likely be Linux 5.0) and since then more changes have been queuing in their work-in-progress branch.

    That last pull request was a big one with AMD Raven2 support, AMD Picasso APU enablement, more Vega 20 upbringing work including initial xGMI support, AMDKFD merging into AMDGPU, VCN JPEG engine support, GPUVM virtual memory improvements, and various other changes as outlined in the aforelinked article.

  • VMware's SVGA Gallium3D Driver Enables OpenGL 3.3 Compatibility Profile Support

    In preparation for the upcoming VMware Fusion 11 and VMware Workstation 15 releases, their Mesa/Gallium3D-based driver stack for Linux guest GPU acceleration has been seeing a variety of updates.

    Earlier this month was a big code push including many new features to its "SVGA" Gallium3D driver like MSAA, a various assortment of new OpenGL extensions, and other changes in step with their latest "VMWGFX" Linux kernel DRM drivers.

  • Sway 1.0 Alpha 6 Released, Now Supports Moving/Resizing Tiled Windows With The Mouse

    Released on Friday was the sixth alpha release of the upcoming Sway 1.0 Wayland compositor release that still strives for compatibility with the i3 window manager workflow.

    Sway 1.0 has already added a ton of new functionality like using the new wlroots Wayland library, output rotation, fractional scaling, daisy-changed DisplayPort monitors, better HiDPI support, DMA-BUF additions for screenshot capture and real-time video capturing, atomic additions, floating window improvements, better multi-GPU support, virtual keyboard protocol support, and a heck of a lot more.

Mesa Can Finally Build With Almost No Compiler Warnings

Filed under
Graphics/Benchmarks

Quite a feat for modern open-source projects with large C/C++ code-bases developed over the years, Mesa3D can almost be compiled now without any warnings -- there's just one remaining.

When paired with the latest GCC 8 stable compiler, Mesa paired with some pending patches is down to just one compiler warning left in the build process -- quite an improvement compared to in the past with older versions of GCC and Mesa.

  • Intel Preparing A Final Batch Of Graphics Driver Changes For Linux 4.20~5.0

    Intel open-source developers have already sent in multiple pull requests of feature work to DRM-Next that in turn will be pulled into the Linux 4.20~5.0 kernel merge window and they have one final batch of feature changes on the way.

    The cut-off is quickly approaching for new feature work slated for this next kernel cycle (Linux 4.20, or renamed to Linux 5.0 if Linus Torvalds sticks to his usual versioning preference) and Intel has announced a batch of changes ready for testing ahead of issuing it as a pull request to DRM-Next.

  • NVIDIA Sends Out DRM Display Patches For Tegra's Xavier SoC

    Going back to the beginning of the year NVIDIA developers have been contributing "Tegra194" enablement to the upstream Linux kernel. They've now moved on to contributing T194 support to the Tegra Direct Rendering Manager (DRM) driver for display support on this SoC that's better known as Xavier.

    The Tegra194 / Xavier is NVIDIA's latest SoC with the eight Carmel ARMv8 cores and Volta-based GPU. The NVIDIA Xavier Developer Kits have begun shipping and now with all of the other necessary hardware enablement bits upstream or on their way to mainline, the latest patches being published are for the display support with the Tegra DRM driver.

  • Mesa 18.2.1 Is Coming This Week With Dozens Of Fixes

    As the first stable point release to the newly-christened Mesa 18.2, the Mesa 18.2.1 release is going to be a big one.

    The release candidate to Mesa 18.2.1 was issued on Wednesday and has nearly 60 patches over the recent 18.2.0 stable release. This includes Vulkan header updates for v1.1.84 and many RADV / ANV Vulkan driver fixes ranging from CTS issues to hangs to other fixes.

  • Mesa 18.2.1 Released With A Number Of Fixes For The Vulkan Drivers

    Mesa 18.2.1 is out this morning as the first stable point release to the recently introduced Mesa 18.2 series. Mesa 18.2.1 marks the point at which it should be relatively safe for stable-minded users to switch over to this quarterly release stream.

    Given it's the first point release after a very active development cycle, there are a lot of fixes: around five dozen changes are making up today's release coming two weeks after v18.2.0.

  • AMD Adds A Seemingly New Polaris ID To Their Linux Driver

    It looks like another re-branded AMD Polaris graphics card might be on the way given the latest AMDGPU Linux kernel patch.

    Either there's a new AMD Radeon "Polaris" graphics card coming, some new modem for OEMs, or just very tardy maintenance in adding the necessary PCI ID for an existing Polaris graphics card revision... But two years after Polaris RX 400 cards first debuted (and a year and a half since the RX 500 series), there is now a new Polaris PCI ID being added to the AMD Linux graphics driver.
