  • AMD Radeon Pro 18.Q3 Linux Driver Released

    AMD has released their Radeon Pro 18.Q3 enterprise driver update, including for supported Linux distributions, as their QA-tested professional-grade driver update for the quarter.

    Radeon Pro Software 18.Q3 is available for RHEL/CentOS 7.5, RHEL/CentOS 6.9, Ubuntu 18.04, Ubuntu 16.04, and SUSE Linux Enterprise Desktop/Server 12 SP3. This is basically the QA-vetted enterprise driver stack of "AMDGPU-PRO" intended for workstation graphics hardware while for the most part those on consumer Radeon GPUs are generally best off riding the latest Linux+Mesa releases for the leading open-source driver coverage.

  • AMDGPU LRU Bulk Move Patches Yielding OpenCL & Vulkan Performance Boosts

    AMD's Huang Rui and Christian Konig are working on LRU bulk move functionality that can yield performance improvements for Vulkan and OpenCL workloads.

    This AMDGPU kernel change is about migrating PD/PT buffer objects onto the LRU (least recently used) list in bulk in a single operation. For end-users, what matters is the performance difference as a result.

  • NVIDIA Vulkan Beta Update Brings Hang Fixes, Device Diagnostic Checkpoints

    NVIDIA has just published their latest Vulkan beta driver release for Windows and Linux.

    The newest NVIDIA Vulkan beta for Linux out today is version 396.51.02. Most notable with this driver update is that it adds support for the VK_NV_device_diagnostic_checkpoints extension. This extension was recently made public by Vulkan 1.1.82 and is for inserting device diagnostic checkpoints.

An Initial Look At The Intel Iris Gallium3D Driver Performance

One of the most exciting developments in the open-source Intel driver space this year was the Iris Gallium3D driver taking shape as what's destined to eventually succeed their "classic" i965 Mesa driver. With Iris Gallium3D maturing, here's a look at how the performance currently stacks up to their mature OpenGL driver. The Intel Iris Gallium3D driver is designed for Skylake (potentially Broadwell too) support and newer generations while being a forward-looking driver and utilizes their mature NIR compiler support. Iris holds much more performance potential than their classic Mesa driver albeit the developers haven't really taken to performance optimizations yet but rather getting the driver up and running, eliminating test suite failures, and getting to the point of feature parity with the i965 driver.
