  • More Radeon & AMDGPU Fixes Line-Up For Linux 4.10

    Alex Deucher has sent in another batch of fixes for the Radeon and AMDGPU DRM drivers for the Linux 4.10 kernel.

    These fixes include support for a few peculiar Southern Islands graphics processors in AMDGPU and Radeon drivers. The affected SI GPUs now supported are those needing the "si58" memory controller microcode. Unfortunately, haven't been able to find much other details on the particular SI chips affected.

  • Mesa 17.0 Saw Less Code Changes Than Earlier Releases, But More Notable Features

    With Mesa 17.0 up to its release candidates and being under a feature freeze, I explored this morning how the size of the changes for Mesa 17.0 compare to earlier Mesa milestones.

    Mesa 17.0 ships with many exciting end-user changes such as OpenGL 4.5 for RadeonSI, OpenGL 4.5 for Haswell, many RADV and ANV Vulkan driver improvements, improved OpenGL 4.x Nouveau support, and many other features I'll recap shortly in a Mesa 17.0 feature overview article.

  • The open source Vulkan driver 'radv' for AMD on Linux has patches for geometry shader support

    Dave Airlie sent in a massive patch-set of 31 patches for 'radv', the open source AMD Vulkan driver, to support geometry shaders.

Intel Kabylake: Windows 10 vs. Linux OpenGL Performance

Filed under
Graphics/Benchmarks

For those curious about the current Kabylake graphics performance between Windows 10 and Linux, here are some OpenGL benchmark results under each operating system. Windows 10 Pro x64 was tested and the Linux distributions for comparison were Ubuntu 16.10, Clear Linux, Antergos, Fedora 25 Xfce, and openSUSE Tumbleweed.

  • RADV Vulkan Driver Has Geometry Shader Support For Testing

    David Airlie has published a set of 31 patches for testing that provide initial support for geometry shaders within the RADV Radeon Vulkan driver.

    While RadeonSI has long supported geometry shaders, it's been a bigger work item bringing it to this open-source Radeon Vulkan driver within Mesa. The patches are enough for Vulkan geometry shaders to get working on RADV, but Airlie explains that the support isn't gold: "This is a first pass at geometry shader support on radv, all the code should be here in reviewable pieces, it seems to mostly pass CTS tests but triggers some llvm 3.9 bugs around kill, and there might still be a GPU hang in here, but this should still be a good place to start reviewing."

  • libinput 1.6.0

    This release fixes the slow touchpad acceleration on touchpads with less than 1000dpi, a missing call to normalized the deltas was the source of the issue.

  • Libinput 1.6 Released With New Touchpad Acceleration

    Libinput 1.6.0 was announced a short time ago on wayland-devel.

  • Mesa 17 Gets a First Release Candidate, Final Planned for Early February 2017

    Collabora's Emil Velikov announced today, January 19, 2017, the availability of the first of many Release Candidate (RC) development versions of the upcoming and highly anticipated Mesa 17.0.0 3D Graphics Library.

    Mesa 17 is shaping up to be a huge milestone that should dramatically improve the performance of the bundled open-source graphics drivers for Intel, AMD Radeon, Nvidia graphics cards on a Linux-based operating system. Just the other day it enabled OpenGL 4.5 support for Intel Haswell GPUs, which is already a big achievement.

NVIDIA Linux OpenCL Performance vs. Radeon ROCm / AMDGPU-PRO

Filed under
Graphics/Benchmarks

Earlier this week I posted some benchmarks of GPUOpen's new Radeon Open Compute ROCm OpenCL stack that premiered last month and they are working to make completely open-source. In those initial benchmarks I compared the ROCm 1.4 OpenCL performance to the existing AMDGPU-PRO OpenCL implementation on Linux. For those wondering how these two Radeon OpenCL stacks compare to NVIDIA, here are some fresh benchmarks.

Fedora vs. Ubuntu vs. openSUSE vs. Clear Linux For Intel Steam Gaming Performance

Filed under
Graphics/Benchmarks

With this week Clear Linux now being able to run Steam, I was excited to see how this performance-minded Linux distribution out of Intel's Open-Source Technology Center would compare to other more popular Linux distributions when it comes to Intel Linux gaming performance. Here are some benchmarks of this traditionally workstation/server-oriented Intel Linux distribution running some Steam Linux games.

For those that haven't read our past articles with Clear Linux benchmarks, it tends to perform very well for a variety of reasons. Delivering the best Linux performance possible on Intel hardware is one of their driving forces and include features like aggressive CFLAGS/CXXFLAGS by default, using CPUFreq over P-State for CPU frequency scaling, building software packages with function multi-versioning to support both older and newer processors, selectively choosing Clang vs. GCC compilers for each package based upon the performance, carrying some out-of-tree patches, and various other optimizations/tweaks as outlined at ClearLinux.org.
