  • AMDVLK Official Open-Source Radeon Vulkan Driver Updated

    It's been one month now since AMD open-sourced their official Vulkan driver code and the associated XGL code-base. There has been about weekly code drops of new AMDVLK/XGL code over the past month while the separate, community-driven Mesa-based RADV Vulkan driver continues being developed as well.

    Marking one month since the open-sourcing of this Radeon Vulkan driver that is shared with the Windows code-base is a new code drop. Today's code drop adds VK_AMD_buffer_marker and VK_EXT_debug_report support. There are also a number of internal Vulkan driver behavior changes and fixes to some conformance test suite bugs.

  • Deep Color Support For Radeon X.Org Driver Being Tackled

    Open-source contributor Mario Kleiner has continued his work on deep color support for the Radeon Linux driver.

  • [ANNOUNCE] libinput 1.9.901

    The first RC for libinput 1.10 is now available.

  • Libinput 1.10 Is On The Way To Remove Touchpad Hysteresis

    eter Hutterer of Red Hat has announced the first release candidate of libinput 1.10 today, which isn't a big feature release but rather incorporates a few new features with many bug fixes for this input handling library used by X.Org and Wayland systems.

    Peter notes the most notable change for libinput 1.10 is the removal of the touchpad hysteresis code. This code was previously used to prevent pointer wobbles while now the code has been worked to analyze the event sequence for pointer wobbles and if none exist the hysteresis won't be applied. This should lead to a more reactive pointer.

    Libinput 1.10 is also working on new button debouncing fixes, improvements for newer Wacom tablets, and a variety of fixes.

  • DXVK Is Making Significant Progress In Implementing Direct3D 11 Over Vulkan

    The DXVK project that started towards the end of 2017 for implementing Direct3D 11 over Vulkan with a focus on improving the D3D11 Wine support is already beginning to run some titles.

Intel OpenGL vs. Vulkan Performance With Mesa 18.0

Filed under
Graphics/Benchmarks

Given the very strong Vulkan vs. OpenGL performance in the recent low-end/older Linux gaming GPU tests with discrete graphics cards, I was curious to run some benchmarks seeing the current state of Intel's open-source OpenGL vs. Vulkan performance. With the Mesa 18.0 release to be branched soon, it was a good time seeing how the Intel i965 OpenGL and ANV Vulkan drivers compare.

EXT4 vs. XFS vs. Btrfs vs. F2FS With Linux 4.15 Comparing KPTI/Retpoline

Filed under
Graphics/Benchmarks

The latest in our benchmarking with KPTI and Retpoline for Meltdown and Spectre mitigation is comparing the performance of the EXT4, XFS, Btrfs and F2FS file-systems with and without these features enabled while using the Linux 4.15 development kernel.

Gaming

A request came in this week to look at how low-end and older graphics cards are performing with current generation Linux games on OpenGL and Vulkan. With ten older/lower-end NVIDIA GeForce and AMD Radeon graphics cards, here is a look at their performance with a variety of native Linux games atop Ubuntu using the latest Radeon and NVIDIA drivers.

  • Mesa 17.3.3 Released With RADV & ANV Vulkan Driver Fixes

    Mesa 17.3.3 is now available as the latest point release for the Mesa 17.3 stable series.

    This bi-weekly point release to Mesa presents several RADV Vega/GFX9 fixes, various Intel ANV Vulkan driver fixes, a DRI3 fix, and random fixes to the OpenGL drivers like RadeonSI, Etnaviv, and even Swrast.

  • R600g "Soft" FP64 Shows Signs Of Life, Enabling Older GPUs To Have OpenGL 4 In 2018

    Most pre-GCN AMD graphics cards are still limited to OpenGL 3.3 support at this time due to not supporting FP64. Only the HD 5800/6900 series on R600g currently have real double-precision floating-point support working right now so at present they are on OpenGL 4.3 rather than 3.3, but those other generations may be catching up soon thanks to the "soft" FP64 code.

  • AMDGPU DC Gets More Raven Ridge Improvements, Audio Fixes

    Harry Wentland of AMD has sent out the latest batch of patches for the AMDGPU DC display code stack. Fortunately it lightens up the DRM driver by about six thousand lines thanks to removing some unused code.

    Besides gutting out a chunk of unused code, the DC code has a few audio fixes (no word yet on supporting newer audio formats with DC), fixes on driver unload, a "bunch" of continued Raven Ridge display updates, and various other code clean-ups.

  • AMDGPU Firmware Blobs Updated For Video Encode/Decode

    There are updated AMDGPU microcode/firmware files now available for recent Radeon GPUs.

    The updated firmware files now available via the main linux-firmware.git repository are centered around the video blocks: UVD video decoding, VCE video encode, and the new VCN video encode/decode block with Raven Ridge.

16-Way Graphics Card Comparison With Radeon On ROCm, NVIDIA With Initial 2018 Linux Drivers

Filed under
Graphics/Benchmarks

Towards the end of December AMD quietly released ROCm 1.7.60 as the newest version of their Radeon Open Compute stack complete with their maturing OpenCL implementation. With the improvements there plus NVIDIA recently introducing their 390 Linux driver series (390.12 Beta currently), I ran some fresh Linux OpenCL GPU compute benchmarks on a variety of AMD and NVIDIA graphics cards for those curious how the current performance stacks up.

Arch Linux vs. Antergos vs. Clear Linux vs. Ubuntu Benchmarks

Filed under
Graphics/Benchmarks

Last week when sharing the results of tweaking Ubuntu 17.10 to try to make it run as fast as Clear Linux, it didn't take long for Phoronix readers to share their opinions on Arch Linux and the request for some optimized Arch Linux benchmarks against Clear Linux. Here are some results of that testing so far in carrying out a clean Arch Linux build with some basic optimizations compared to using Antergos Minimal out-of-the-box, Ubuntu Server, and Clear Linux.

Tests this time around were done on the Intel Core i9 7980XE system with ASUS PRIME X299-A motherboard, 4 x 4GB DDR4-3200 Corsair memory, GeForce GTX 750, and Corsair Force MP500 120GB NVMe solid-state drive. The system with 18 cores / 36 threads does make for quick and easy compiling of many Linux packages.

  • RadeonSI NIR Backend Now Supports GLSL 4.50

    The experimental RadeonSI NIR back-end is taking a final step forward for Mesa 18.0.

    Up until today when using the RadeonSI NIR code-path the GLSL (OpenGL Shading Language) version was limited to 1.50 due to not having any tessellation shader support, but now it's supported up through 4.50 -- the GLSL version matching OpenGL 4.5.

  • RADV Vulkan Driver Now Supports VK_EXT_debug_report

    With the flurry of Mesa development activity with Mesa 18.0 being branched in a few days, the RADV Radeon Vulkan driver picked up support for another extension.

    Building off groundwork laid by Intel ANV, the RADV driver now implements VK_EXT_debug_report. At the moment it doesn't output any messages but can be easily added during development for usage with RenderDoc and other Vulkan debuggers.

  • The DRM Graphics Driver Changes Coming For Linux 4.16

    With being past the cutoff of new features to be merged to DRM-Next for targeting the upcoming Linux 4.16 kernel merge window, here is a recap of the prominent changes to the Direct Rendering Manager drivers for this next kernel cycle.

  • Interview with Baukje Jagersma
    How and when did you get to try digital painting for the first time? Probably when I first discovered Deviantart. I was already familiar with GIMP, which I used to create photo-manipulations with. But seeing all the amazingly talented artists on there made me want to try out digital painting for myself.
  • Builder happenings for January
    I’ve been very busy with Builder since returning from the holidays. As mentioned previously, we’ve moved to gitlab. I’m very happy about it. I can see how this is going to improve the engagement and communication between our existing community and help us keep new contributors. I made two releases of Builder so far this month. That included both a new stable build (which flatpak users are already using) and a new snapshot for those on developer operating systems like Fedora Rawhide.
