Linux
  • BUS1 Still Remains Out Of The Mainline Linux Kernel, But DBus-Broker Continues

    The BUS1 in-kernel IPC mechanism born out of the ashes of KDBUS still hasn't been mainlined in the Linux kernel, but its code is still improved upon from time to time. At least though DBus-Broker as a new performance-oriented D-Bus implementation continues gaining ground in user-space.

    DBus-Broker was announced last year as a new message bus implementation of D-Bus focused on high performance and reliability while continuing to offer compatibility with the original D-Bus implementation.

  • Linux 4.17-rc2 Kernel Released With Mostly Routine Changes

    Linus Torvalds has announced the availability of the second weekly test release for what is becoming the Linux 4.17 kernel.

  • Wayland's Weston Gets Optimizations For Its Pixman Renderer

    Wayland's Weston reference compositor with its Pixman software-based renderer back-end has received a number of performance optimizations.

    Fabien Lahoudere of Collabora posted a set of patches today to optimize the Pixman renderer for Weston. In particular, there are optimizations around compositing damage to the screen as well as optimizing the shadow buffer usage. The Weston Pixman renderer is often used as a software accelerated fallback in cases where no GPU hardware acceleration may be available. As implied by the name, it uses the long-standing Pixman library that is also used by Cairo, the X.Org Server, etc, for pixel manipulation on the CPU.

  • Panfrost Gallium3D Driver For ARM Mali Can Now Render A Cube

    The Panfrost open-source driver project previously known as "Chai" for creating an open-source 3D driver stack for ARM's Mali Midgard hardware now has a working shaded cube being rendered using the open-source code as part of its new "half-way" driver based on Gallium3D.

Ryzen 7 2700X CPUFreq Scaling Governor Benchmarks On Ubuntu Linux

Filed under
Graphics/Benchmarks

With this week's Ryzen 5 2600X + Ryzen 7 2700X benchmarks some thought the CPUFreq scaling driver or rather its governors may have been limiting the performance of these Zen+ CPUs, so I ran some additional benchmarks this weekend.

Those launch-day Ryzen 5 2600X / Ryzen 7 2700X Ubuntu Linux benchmarks were using the "performance" governor, but some have alleged that the performance governor may now actually hurt AMD systems... Ondemand, of course, is the default CPUFreq governor on Ubuntu and most other Linux distributions. Some also have said the "schedutil" governor that makes use of the kernel's scheduler utilization data may do better on AMD. So I ran some extra benchmarks while changing between CPUFreq's ondemand (default), performance (normally the best for performance, and what was used in our CPU tests), schedutil (the newest option), and powersave (if you really just care about conserving power).

    AMD developers maintaining their official Vulkan cross-platform driver code have pushed their end-of-week updates to their external source repositories for those wanting to build the AMDVLK driver on Linux from source.

    This latest AMDVLK push updates not only their PAL (Platform Abstraction Layer) and XGL (Vulkan API Layer) components but it also updates their fork of the LLVM code-base used for their shader compilation.

  • EGLStreams XWayland Code Revised Ahead Of X.Org Server 1.20

    It's still not clear if the EGLStreams XWayland support will be merged for xorg-server 1.20 but at least the patches were revised this week, making it possible to merge them into this next X.Org Server release for allowing the NVIDIA proprietary driver to work with XWayland.

  • Vulkan 1.1.74 Released With Minor Fixes & Clarifications

    Vulkan continues sticking to the "release early, release often" mantra with the availability today of Vulkan 1.1.74.

DragonFlyBSD 5.2, TrueOS 18.03, FreeBSD 11.1, Ubuntu 16.04/18.04 & Clear Linux Tests

Filed under
Graphics/Benchmarks

This week I posted some benchmarks looking at the Meltdown mitigation impact on BSD vs. Linux as well as some tests of DragonFly's stabilized HAMMER2 while for your viewing pleasure this weekend are a variety of general BSD vs. Linux benchmarks while using the newly-released DragonFlyBSD 5.2, TrueOS 18.03, FreeBSD 11.1, Ubuntu 16.04 LTS, Ubuntu 18.04, and Intel's Clear Linux.

All of these BSD/Linux operating system benchmarks were done using a system with an Intel Xeon E3-1280 v5 Skylake CPU, MSI MS-7998 motherboard, 2 x 8GB DDR4-2133 memory, and a 256GB Toshiba RD-400 NVMe SSD. All of the hardware components were maintained the same throughout the entire testing process.

For making the systems comparable and testing the operating systems in the manner set by the vendor, each platform was tested "out of the box" using the default settings.

  • AMDGPU DC Fixes For Linux 4.17 Take Care Of "The Dark Screen Issue"

    AMD's Alex Deucher has sent in a small set of fixes for the AMDGPU Direct Rendering Manager driver in the Linux 4.17 kernel.

    The three patches are for fixing a dark screen issue with AMDGPU DC, a fix for clock/voltage dependency tracking for WattMan, and an updated SMU interface for the yet-to-be-announced Vega 12 GPU.

  • Intel KVMGT 2018-Q1 Release Offers Mediated GPU Pass-Through Improvements

    While the relevant bits for supporting Intel GPU mediated pass-through to virtual machines with KVM are now upstream in the Linux kernel as well as in QEMU 2.12, Intel developers have just announced their quarterly release of "KVMGT" for those wanting the officially blessed configuration for running Intel virtual GPU support with KVM virtual machines.

    Earlier this month we covered "The Forge" picking up initial Linux support and now they have rounded out their full-featured Linux support with Vulkan rendering.

This Chart Shows How The Radeon RX 580 vs. GeForce GTX 1060 Now Compete Under Linux

Filed under
Graphics/Benchmarks

It was just last year that open-source RadeonSI/RADV developers were trying to get the Radeon RX 580 "Polaris" GPU to be competitive with the GeForce GTX 1060 as it is under Windows given each GPU's capabilities. We've seen the RX 580 and GTX 1060 dancing under Linux the past few months and yesterday's 20-way GPU comparison with Rise of the Tomb Raider was quite significant -- perhaps most surprising being how well the RX 580 performed. Heck, just one or two years ago it was an accomplishment seeing any official Radeon driver support at-launch for new Linux game releases. So here are some extensive tests looking closer at the GTX 1060 vs. RX 580 battle in this latest Vulkan-powered Linux game port.

Graphics/Benchmarks
Gaming

Today Feral Interactive released their much anticipated Linux port of Rise of the Tomb Raider, the game that was released for Windows in January of 2016 and then released for macOS last week. Feral's Mac port was relying upon the Apple Metal API while the Linux port is now their second game (after F1 2017) exclusively relying upon the Vulkan graphics/compute API rather than OpenGL. This morning I posted the initial Radeon results using the RADV driver while here is the NVIDIA GeForce vs. AMD Radeon graphics card comparison on Ubuntu Linux using twenty different graphics cards.

  • AMDGPU DRM Gets "GFXOFF" Patches To Turn Off Graphics Engine

    AMD's Huang Rui has posted a set of 20 patches providing "GFXOFF" support for the AMDGPU Direct Rendering Manager Linux kernel driver.

    GFXOFF is a new graphics processor feature that allows for powering off the graphics engine when it would otherwise be idle with no graphics workload. Obviously, this would equate to a potentially significant power savings with that engine being able to be shut-off.

  • RADV Driver Lands Support For Vulkan's New Descriptor Indexing Extension

    Earlier this month with the Vulkan 1.1.72 specification update was the new VK_EXT_descriptor_indexing extension that is quickly being well received by developers.

    The VK_EXT_descriptor_indexing extension allows for creating large descriptor sets made up of all their combined resources and selecting those resources via dynamic indexes in a shader.

  • RadeonSI Now Appears To Support "RX Vega M" With Intel Core CPUs

    One of the most common Linux hardware questions I've received dozens of times in the past few weeks alone has been over the support for "RX Vega M" Vega-based graphics processors found on select newer Intel Kabylake CPUs. It appears RadeonSI at least should now support these Radeon graphics on Intel CPUs.

  • Linux app support coming to older Chrome OS devices
    Linux apps on Chrome OS is one of the biggest developments for the OS since Android apps. Previous reports stated Chromebooks with certain kernel versions would be left in the dust, but the Chrome OS developers have older devices on the roadmap, too. When Google first broke silence on Linux app functionality, it was understood that Linux kernel 4.4 was required to run apps due to dependencies on newer kernel modules. Thanks to an issue found on Chromium’s public bugtracker, we have confirmation that containers won’t be limited to the handful of Chrome OS devices released with kernel 4.4.
  • Looking Ahead To The Linux 4.18 Kernel
    There still are several weeks to go until the Linux 4.17 kernel will be officially released and for that to initiate the Linux 4.18 merge window, but we already know some of the features coming to this next kernel cycle as well as an idea for some other work that may potentially land.
