  • Intel Has More P-State Changes Coming For Linux 4.12

    Tuning the P-State CPU frequency scaling driver for the Linux kernel feels like a never-ending process. While it's been around for years and continues to be refined, for some Intel CPUs on some workloads, the CPUFreq scaling driver leads to be better performance and even Intel's own Clear Linux distribution is using CPUFreq by default. With Linux 4.12, more intel_pstate revisions are taking place.

  • Intel's Vulkan Driver Working On VK_KHX_multiview Support

    Intel's open-source "ANV" Vulkan Linux driver is prepping support for the experimental VK_KHX_multiview extension.

    Key Intel Vulkan driver contributor Jason Ekstrand has published his initial patches for VK_KHX_multiview support within the ANV code-base. This also includes SPIR-V support for the related SPV_KHR_multiview extension.

  • Mir's Abstraction Layer Now Has Cut & Paste Support (MirAL)

  • Nouveau TGSI Shader Cache Enabled In Mesa 17.1 Git

    Building off the work laid by Timothy Arceri and others for enabling a TGSI (and hardware) shader cache in the RadeonSI Gallium3D driver as well as R600g TGSI shader cache due ot the common infrastructure work, the Nouveau driver is now leveraging it to enable the TGSI shader cache for Nouveau Gallium3D drivers.

This Week's Mesa 17.1-dev + Linux 4.11 Radeon Performance vs. NVIDIA

Filed under
Graphics/Benchmarks

Given all the recent performance work that's landed recently in Mesa Git for Mesa 17.1 plus the Linux 4.11 kernel continuing to mature, in this article are some fresh benchmarks of a few Radeon GPUs with Mesa 17.1-dev + Linux 4.11 as of this week compared to some GeForce graphics cards with the latest NVIDIA proprietary driver.

Basically this article is to serve as a fresh look at the open-source Radeon vs. closed-source NVIDIA Linux gaming performance. The Radeon tests were using the Linux 4.11 kernel as of 20 March and the Mesa 17.1-dev code also as of 20 March. The NVIDIA driver used was the 378.13 release. Ubuntu 16.10 was running on the Core i7 7700K test system.

  • Yaakuro shows off SteamVR on Unreal Engine 4 using Vulkan on Linux

    Previously Yaakuro worked to make Unreal Engine 4 work with SteamVR using OpenGL on Linux, but now he's moved onto making it work with Vulkan!

  • Unreal Engine 4 Making Progress On Linux With Vulkan & SteamVR

    Thanks to the work of community UE4 developer Yaakuro, Unreal Engine 4 on Linux with SteamVR support is advancing and can now be used with Vulkan rendering.

    Earlier this month the developer got UE4 with SteamVR on Linux running but using the OpenGL renderer. But today he's shared a video showing off UE4 on Linux SteamVR with Vulkan.

  • Khronos Clarifies That Vulkan Multi-GPU Isn't Limited To Windows 10

    With the big Vulkan 1.0.42 update came a number of new extensions, including for Vulkan multi-GPU/device support. There was some confusion by some that Vulkan's multi-GPU support was limited to Windows 10, but that is not at all the case.

    It appears some confusion came up about Vulkan's multi-GPU support when some Game Developers Conference (GDC17) slides had referenced the Windows Display Driver Model (WDDM). Thus some thought the Vulkan multi-device capabilities were somehow tied to using Windows' WDDM.

  • Radeon Vega Changes For Libdrm, Plans For Merging Prior To Kernel Support

    The latest in the hardware enablement work for adding support for the upcoming Radeon RX Vega to the open-source Linux graphics driver are the patches to libdrm for this Mesa DRM library that sits between the DRM kernel drivers and Mesa / xf86-video / other user-space graphics code.

  • More Radeon Vega Work Lands For LLVM 5.0

    Yesterday we saw 100 patches adding Vega support to the Radeon DRM driver as well as 140 patches adding Vega support to RadeonSI Gallium3D. The other big piece of the open-source Linux driver stack for Vega is the AMDGPU LLVM changes.

  • Porting Mesa/Libdrm's Build System To Meson Brings Up Controversy

    Last week an independent developer proposed replacing the build system of libdrm -- the DRM library that sits between Mesa and the Linux kernel DRM -- to using the Meson build system as a potential replacement to using Autotools. That has led to another colorful discussion around build systems.

    Dylan Baker's RFC patches can be found on the dri-devel list and the discussion that ensued. He argues that the build system with Meson would be better since it's written in Python, Meson makes use of Ninja rather than CMake, its syntax is arguably simpler, and it's quicker. Dylan found that his build times dropped from 26 seconds to 13 seconds when going from Autotools to Meson. When making use of ccache, the build times dropped from 13 seconds to 2 seconds. He also mentioned he's planning on porting Mesa's Autotools/CMake build system over to Meson.

  • AMD’s Linux GPU patches seven Vega 10s

    These 100 patches add up to 40,000 lines of code and have been sent out today for review. The idea is that AMD will use them as the basis to provide "Vega 10" support within the Linux AMDGPU DRM driver.

  • Seven AMD Vega GPU IDs have appeared in the latest Linux driver release

    More than forty thousand lines of updated code have been sent out with 100 little patches for AMD’s Linux graphics drivers so they can deliver Vega GPU support when the new architecture launches. Inside the latest drivers have appeared seven discrete Vega 10 device IDs.

  • AMD Sends Out 100 Patches, Enabling Vega Support In AMDGPU DRM

    100 patches amounting to over fourty thousand lines of code was sent out today for review in order to provide "Vega 10" support within the AMDGPU DRM driver.

    Adding Vega support to AMDGPU is a big task due to all of the changes over Polaris and other recent GPUs. Vega rolls out a new video BIOS interface, lots of new hardware intellectual property, support for video decode using UVD (UVD 7.0), support for video encode using VCE (VCE 4.0), support for 3D via RadeonSI, power management, full display support using DC, and support for SR-IOV virtualization.

  • Are Low-Code Platforms a Good Fit for Feds?
    Open-source code platforms — in part, because they’re often free — have long been a popular choice for digital service creation and maintenance. In recent years, however, some agencies have turned to low-code solutions for intuitive visual features such as drag-and-drop design functionality. As Forrester Research notes, low-code platforms are "application platforms that accelerate app delivery by dramatically reducing the amount of hand-coding required."
  • Crunchy Data Brings Enterprise Open Source POSTGRESQL To U.S. Government With New DISA Security Technical Implementation Guide
