AMDVLK Still Has Some Performance Advantages Over Mesa's Radeon RADV Vulkan Driver, But It's A Good Fight

Filed under
Graphics/Benchmarks

As it's been a while since our last comparison of the two AMD Vulkan drivers for Linux gaming and with getting the Radeon VII situation straightened out here are some fresh benchmarks of the latest AMDVLK and RADV Vulkan drivers when running various Ubuntu gaming benchmarks with Radeon RX Vega 64 and Radeon VII graphics cards.

The AMDVLK Vulkan driver tests were using the new 2019.Q2.4 release while the RADV Vulkan driver was using Mesa 19.2.0-devel via the Oibaf PPA. All tests were done from Ubuntu 19.04 while running with a Linux 5.1 kernel. The only changes to the system were swapping of the RADV/AMDVLK drivers and testing both the Radeon RX Vega 64 and Radeon VII graphics cards for the current summer 2019 Vulkan gaming performance.

OpenSUSE Leap 15.1 Is Performing Very Well On AMD EPYC

Filed under
Graphics/Benchmarks
SUSE

OpenSUSE/SUSE has always tended to perform well on AMD hardware given the close collaboration between the two companies for many years on numerous fronts going back to the original Linux AMD64 kernel upbringing to the RadeonHD driver days, compiler collaboration, and numerous other activities between SUSE and AMD. With last week's release of openSUSE Leap 15.1, the performance on AMD EPYC servers is even more competitive thanks to various upgrades.

OpenSUSE Leap 15.1 was released last week and based off the sources of SUSE Linux Enterprise 15 SP1. Leap 15.1 updates its Linux 4.12 kernel with more back-ports/upgrades, updates various components from systemd to other packages, minor improvements to its GCC7 compiler (also offering a GCC8 option though not tested as part of this article), Java OpenJDK 11 by default, and other upgrades.

Mesa 19.1's New Features From The Intel Gallium3D Driver To New Drivers & Vulkan Optimizations

Filed under
Graphics/Benchmarks

Mesa 19.1 should be out any day now as the new quarterly feature release for this collection of open-source graphics drivers predominantly used on Linux systems. While we cover the Mesa development features on a near daily basis, here is a recap of all the exciting changes and new features to find with the upcoming Mesa 19.1.

Mesa 19.1 is quite a significant step forward for open-source graphics drivers. Mesa 19.1 brings multiple new OpenGL/Vulkan drivers and plenty of improvements to the existing drivers. Among the changes worked on for Mesa 19.1 over the past three months include:

- Arguably the biggest change with Mesa 19.1 is the introduction of their new Gallium3D driver called Iris while supporting all HD/UHD/Iris Graphics hardware going back to the Gen8 Broadwell days. Broadwell is the oldest Intel hardware to be supported by this new Gallium3D driver while the earlier Gen hardware will still be supported by the mature i965 driver. The Intel Gallium3D driver isn't yet enabled by default in place of their existing driver but that is a goal they have to address by year's end. In our benchmarking of the Intel Gallium3D driver on Mesa 19.1 at least for Skylake and newer, the Gallium3D performance is already comparable (or exceeding) their classic OpenGL driver.

  • Linux 5.1.5 Kernel Fixes The Latest Data Corruption Bug

    For those concerned by the kernel's most recent data corruption bug involving LVM, dm-crypt, and Samsung SSD drive combinations leading to FSTRIM/Discard wiping too much data, the issue should be resolved in the newly-minted Linux 5.1.5 kernel. 

    The Linux 5.1.5 kernel debuted on Saturday with this fix as well as various other kernel fixes. 

  • Intel's Linux OpenGL/Vulkan Drivers Seeing Minor Performance Gains With Mesa 19.1

    With Mesa 19.1 due to be released in the coming days as the quarterly update to this open-source OpenGL/Vulkan driver stack, here are some fresh benchmarks looking at how the current Intel (i965) OpenGL and ANV Vulkan drivers performance compare to that of the existing Mesa 19.0 stable series.

  • X.Org Server Closer To Better Handling On-Demand XWayland Startup

    Merged this week to the X.Org Server code-base was an EGL-based GLX provider for helping XWayland and allowing some games to run nicely now under this X11 code-path for Wayland compositors. While not yet merged, another interesting bit of XWayland code is now under review as a merge request.

    The code by Carlos Garnacho is for handling surface creation should the client come up before the compositor. This functionality is necessary for on-demand start-up of XWayland so it's only running when actively used. The on-demand approach that jives better with this XWayland code pending is the compositor setting up a display socket, listening for incoming data, and only spawning XWayland when there are incoming requests from a launched X11 client.

The RadeonSI/RADV Performance With Mesa 19.1

Filed under
Graphics/Benchmarks

If all goes well, Mesa 19.1 could debut as soon as next week. Here is a look at how the AMD Radeon Polaris and Vega performance is looking with Mesa 19.1 relative to Mesa 19.0 stable.

These are some OpenGL (RadeonSI) and Vulkan (RADV) driver benchmark results I carried out earlier this month looking at the Mesa 19.1-devel performance around the RC1 release compared to Mesa 19.0.2 stable of the time.

A Sapphire Radeon RX 590 (Polaris) and Radeon RX Vega 64 (Vega) were used in this testing to see how the RadeonSI/RADV driver performance has evolved over the past quarter. Via the Phoronix Test Suite a variety of benchmarks were carried out, including various Steam Play (Proton / DXVK) titles.

  • Intel Linux Graphics Driver Adding Support For The Mule Creek Canyon PCH

    Mule Creek Canyon is the PCH to be paired with Intel Elkhart Lake processors. Elkhart Lake as a reminder is the Gemini Lake SoC successor that will feature Gen11 class graphics and now thanks to the open-source Intel Linux graphics driver we know that new PCH is the Mule Creek Canyon.

    Mule Creek Canyon doesn't appear to be widely publicized up to this point but appeared in today's latest open-source development activity. Mule Creek Canyon is the new PCH for Elkhart Lake and required some minor changes around Port-C remapping that differ from other Icelake graphics hardware.

  • XWayland Receive An EGL-Based GLX Provider, Helping Various Games On Linux

    A notable improvement was merged into the "xserver" Git tree for the eventual X.Org Server 1.21 release that will improve the support for various Linux games relying on XWayland for running under a Wayland compositor.

  • Vulkan 1.1.109 Released With Two New Intel Extensions

    With two weeks having passed since Vulkan 1.1.108 there are a few different documentation corrections/clarifications. There are also two new vendor extensions contributed by Intel.

Benchmarking AMD FX vs. Intel Sandy/Ivy Bridge CPUs Following Spectre, Meltdown, L1TF, Zombieload

Filed under
Graphics/Benchmarks

Now with MDS / Zombieload being public and seeing a 8~10% performance hit in the affected workloads as a result of the new mitigations to these Microarchitectural Data Sampling vulnerabilities, what's the overall performance look like now if going back to the days of AMD FX Vishera and Intel Sandybridge/Ivybridge processors? If Spectre, Meltdown, L1TF/Foreshadow, and now Zombieload had come to light years ago would it have shaken that pivotal point in the industry? Here are benchmarks looking at the the performance today with and without the mitigations to the known CPU vulnerabilities to date.

As I've already delivered many benchmarks of these mitigations (including MDS/Zombieload) on newer CPUs, for this article we're looking at older AMD FX CPUs with their relevant Spectre mitigations against Intel Sandybridge and Ivybridge with the Spectre/Meltdown/L1TF/MDS mitigations. Tests were done on Ubuntu 19.04 with the Linux 5.0 kernel while toggling the mitigation levels of off (no coverage) / auto (the default / out-of-the-box mitigations used on all major Linux distributions for the default protections) / auto,nosmt (the more restricted level that also disables SMT / Hyper Threading). The AMD CPUs were tested with off/auto as in the "auto,nosmt" mode it doesn't disable any SMT as it doesn't deem it insecure on AMD platforms.

The fight to keep open source truly “open” ⁠— open source providers need to stand up

However, as more projects get embedded into profitable business applications, we are beginning to see new trends in the space. Powerful vendors are pushing their own marketing agendas and monetising what should be freely available, leading open source providers to build walls around their code, limiting the extent to which companies can enrich, police and contribute to any given project, in a vicious cycle. This is the case with Amazon, for instance, which was able to profit from Redis Labs’ software without giving back to its open source community. In response, Redis Labs created a new software license that dictated clear restrictions on what could and could not be done with its software. [...] With more companies catching on to the ability to monetise open source by selling add-on support and enterprise services, huge technology players are scrambling to get into the scene. To demonstrate just how critical open source is to the software industry, in 2018 alone GitHub was bought for $7.5 billion, Salesforce purchased Mulesoft for $6.5 billion, and — the largest deal of them all — IBM took over Red Hat for $34 billion.
