  • Intel Open-Sources LLVM Graphics Compiler, Compute Runtime With OpenCL 2.1+

    Now it's clear why Intel hasn't been working on the Beignet code-base in months as they have been quietly working on a new and better OpenCL stack and run-time! On open-source Intel OpenCL you can now have OpenCL 2.1 while OpenCL 2.2 support is on the way.

    Intel by way of their Open-Source Technology Center quietly open-sourced a new compute runtime as well as an LLVM-based graphics compiler. Thanks to a sharp-eyed Phoronix reader for spotting and pointing out to us this new Intel OpenCL stack that hasn't really received any attention at all yet.

  • DRI3 v1.1 Updated by Collabora For Modifiers & Multi-Plane Support

    As a sign that DRI3 v1.1 is hopefully ready to go, Louis-Francis Ratté-Boulianne of Collabora on Friday sent out his latest set of patches adding modifiers and multi-plane support to the Direct Rendering Infrastructure.

    DRI3 v1.1 has been a long, ongoing project for this first major addition to the DRI3 infrastructure. Namely there is support for explicit format modifiers and pixmaps backed by multi-planar buffers. Collabora has also already been working on some experimental DRI3 v1.2 patches for DMA fences, which originally was part of the v1.1 patches, but then pushed back to their own series.

  • Mir 0.30 Released With Improved Wayland Support

    Canonical's Mir team has released Mir v0.30 as the latest version of this display server that for the past year has been retooling itself with Wayland protocol support.

    With today's Mir 0.30 release, they have continued on their Wayland conquest and are offering better support for Wayland protocols. Some of the Wayland changes in Mir 0.30 include a client connection change to allow Wayland clients to work on Unity 8, a keyboard state change to fix switching between clients, multiple crash fixes, and experimental support for the XDG-Shell v6 protocol.

  • NVIDIA Preparing Upstream Linux Kernel Support For The Tegra Xavier SoC

    NVIDIA has begun work on sending out patches for upstreaming Tegra194 "Xavier" SoC support within the Linux kernel.

    Xavier is NVIDIA's successor to the Tegra P1 and will begin sampling this quarter. Xavier makes use of a custom ARMv8 eight-core CPU, Volta-based graphics with 512 CUDA cores, integration of the DLA tensor processing unit, and is manufactured on a 12nm FinFET process. Xavier should be a mighty powerful SoC for their self-driving car systems and other "edge computing" use-cases.

  • AMD May Have Accidentally Outed Vulkan 1.1

    AMD on Wednesday released the Radeon Pro Software Enterprise Edition 18.Q1 for Linux driver. It really isn't noticeable for its official changes, but does claim to advertise Vulkan 1.1 support.

  • mesa 17.3.4

    Mesa 17.3.4 is now available.

  • Mesa 17.3.4 Released With 90+ Changes

    While Mesa 18.0 should be released in the days ahead as the latest feature release to Mesa 3D, backporting of fixes/improvements to Mesa 17.3 isn't letting up. For those using this stable series from last quarter, Mesa 17.3.4 is out today with nearly 100 changes.

  • Wayland Protocols 1.13 Introduces New Input Timestamp Protocol

    Jonas Ådahl on Wednesday announced Wayland-Protocols 1.13, the collection of stable and unstable protocols to Wayland.

    The single major change to Wayland Protocols 1.13 is the introduction of the input-timestamps protocol. This protocol extension is for providing high resolution timestamps for input events.

  • Intel's Mesa Driver Gets Patches For New EXT_shader_framebuffer_fetch

    Open-source Intel driver developer Francisco Jerez has sent out a set of 15 patches implementing a new version of the EXT_shader_framebuffer_fetch OpenGL extension.

    EXT_shader_framebuffer_fetch in its current form on the OpenGL registry is for OpenGL ES 2.0+ and allows a fragment shader to read existing frame-buffer data as input. This is intended to allow for more advanced compositing operations.

  • Marek Updates OpenGL 3.1 ARB_compatibility Support For Mesa

    Last October well known open-source AMD driver developer Marek Olšák began work on OpenGL compatibility profile support for Mesa. This work is about OpenGL 3.1 with ARB_compatibility support, something generally relevant for workstation OpenGL users and one of the few remaining advantages of AMD's current proprietary OpenGL driver.

  • AMDVLK/XGL Gets Vega Enhancements, LLPC Optimizations

    AMD developers working on their official, cross-platform XGL/AMDVLK driver code have pushed out another batch of changes for benefiting their official AMD Vulkan Linux driver.

    The first noted change is "enhance GFX9 support", in other words, the Vega GPU support should be in better shape but they didn't provide any specifics. This is good news considering my latest AMDVLK vs. RADV Vulkan driver testing from this weekend still showed several areas where the AMDVLK driver was lagging behind RADV in Radeon RX Vega 64 performance or even not working for some games.

  • X.Org Server Patches Updated For Non-Desktop & Lease Handling

    Keith Packard has sent out his latest patches for implementing the non-desktop and DRM lease functionality from within the X.Org Server. This work also includes the relevant DDX bits being wired through for the xf86-video-modesetting driver.

    The "non-desktop" handling is the new property for indicating if a display output is not for a conventional desktop use-case, i.e. a VR HMD as the main use-case from Valve's perspective. When the VR HMD or other non-desktop output is set, it's not used by the X.Org Server and any desktop window manager so it can be reserved for the SteamVR compositor.

  • RADV Radeon Vulkan Driver Is Still A Better Bet Than AMDVLK In February 2018

    With the AMDVLK Radeon Vulkan driver that AMD open-sourced in December continuing to be updated in weekly batches with new Vulkan extensions / features / performance optimizations and the RADV Mesa-based Radeon Vulkan driver continuing to march to its own beat, I have spent the past few days conducting some fresh benchmarks between the AMDVLK and RADV Vulkan drivers with RX 560, RX 580, and RX Vega 64 graphics cards.

  • Virtualizing GPU Access

    Virtualized GPU access is becoming common in the containerized and virtualized application space. Let's have a look at why and how.

    For the past few years a clear trend of containerization of applications and services has emerged. Having processes containerized is beneficial in a number of ways. It both improves portability and strengthens security, and if done properly the performance penalty can be low.

    In order to further improve security containers are commonly run in virtualized environments. This provides some new challenges in terms of supporting the accelerated graphics usecase.

  • Wayland 1.15 & Weston 4.0 Now Planned For Release In April

    Wayland 1.15 and the Weston 4.0 compositor had been planned for release in February but Wayland developers decided there was still enough material on the verge of landing that they decided to delay the release. A new release schedule has now been put forward for getting these updates out in April.

    Derek Foreman of the Samsung OSG has stepped up to manage this revised Wayland 1.15 / Weston 4.0 release. Now that the "high priority" work has been merged, Derek is ready to move on with wrangling the release.

  • Xorgproto 2018.2 Released To Fix The Fallout Of This New X.Org Package

    Last week marked the inaugural release of Xorgproto, a new package consisting of all the X.Org protocol headers rather than being in standalone packages now that X.Org Server development is slowing down and that many of these protocol headers wind up getting updated at the same time. Today marks the Xorgproto 2018.2 release.
