  • 2D Rendering On X11 Remains Barely Faster Than CPU Rendering

    In addition to being the organizer of XDC2016, Martin Peres also participated in several presentations at this week's conference in Helsinki. One of these pesentations by Martin was concerning 2D X.Org acceleration.

    Martin basically presented on that rendering 2D on a modern X.Org Server is barely faster than CPU rendering, unless compositing. While being barely faster, it consumes more power than CPU-only rendering. But the good news is that more and more software is moving away from X-based rendering.

    With the next GTK+ release there will be the GTK Scene Kit, Qt5 already has changed its renderer, and other projects are moving over to purely CPU-based rendering or GPU rendering with projects like Servo's WebRender, Google's Skia, and the new Intel FastUIDraw project.

  • Don't Expect An Open-Source NVIDIA Vulkan Driver Anytime Soon
  • AMD's DAL Was Just Presented At XDC2016, Still Not Clear When It Will Be Mainlined

    Harry Wentland of AMD just presented at the XDC2016 conference about DAL, the big Display Abstraction Layer code-base, which many AMD Linux users have been waiting to see merged in order to have Polaris audio support and this is one of the stepping stones for seeing FreeSync/Adaptive-Sync and other modern display capabilities.

    We have been covering DAL for months since AMD open-sourced it and since then they've been trying to clean it up, remove some redundancies compared to what core DRM offers, etc. DAL is a big piece of the puzzle that's left for getting mainlined so the AMDGPU open-source kernel driver can be closer to feature parity with the closed-source driver and what's provided on Windows.

  • The Open-Source Intel Vulkan Linux Driver's Anatomy

    Intel Open-Source Technology Center developer Jason Ekstrand presented earlier today at XDC2016 with a presentation entitled "The Anatomy of a Vulkan Driver" where he covers how he and fellow Intel developers brought up the first open-source Vulkan driver and had it ready for launch-day when Khronos formally unveiled the specification earlier this year.

    The early part of the presentation will be boring to anyone who frequently reads Phoronix with the dozens of articles I've written since February concerning progress on the Intel Vulkan driver, Vulkan itself, etc. The early part of the presentation just provides a basic overview of what is Vulkan, the need for Vulkan, etc etc... But the latter half of the presentation is what's interesting when he talks more about the design decisions, how he and basically three Intel developers brought up this driver (along with the support of many other Intel developers), and other commentary surrounding the Intel Linux Vulkan driver's design.

  • Nouveau 1.0.13 X.Org Driver Released

    The latest stable release of the Nouveau X.Org driver is now available for users of this open-source NVIDIA DDX component in conjunction with the Nouveau DRM kernel driver.

    The xf86-video-nouveau 1.0.12 release happened nine months ago so there are some changes that came together in that tine, but then again the most interesting innovations in the open-source Linux graphics stack fall outside the DDX drivers the past few years. In total since the v1.0.12 release were just seven commits.

  • How Google's Android Runtime On Chrome OS Uses Wayland, DRM

    Google developer David Reveman presented at this morning's XDC2016 conference in Finland about the Android Runtime for Chrome making use of Wayland (ARC++) and how the rest of its graphics stack looks for running Android programs on Chrome OS.

    For rendering with ARC++, Gralloc and the OpenGL ES driver are using the Direct Rendering Manager, applications have full access to OpenGL ES, and there are support for other rendering APIs. Compositing with ARC++ is handled by the Android HWComposer and then surfaces are forwarded to Chrome for compositing with the rest of Chrome OS' user-interface.

  • Wayland 1.12 Next-Gen Linux Display Server Officially Released with Many Goodies

    Today, September 21, 2016, Bryce Harrington has had the great pleasure of announcing the immediate availability of the Wayland 1.12.0 display server for GNU/Linux operating systems, along with the Weston 1.12.0 compositor.

    Development for Wayland 1.12 and Weston 1.12 started exactly a month ago when the first Alpha build was seeded to public testers, and it already contained many of the new functionalities and improvements implemented in this final build we can install today on our GNU/Linux distributions.

  • ARB_ES3_2_compatibility Turned On For Intel Broadwell And Newer

    The Intel Mesa OpenGL driver now exposes the ARB_ES3_2_compatibility extension.

    The Intel i965 Mesa DRI driver has already supported the necessary extensions for OpenGL ES 3.2 support while this ARB_ES3_2_compatibility extension signifies that features found in GLES 3.2 but missing from OpenGL 4.5 are present in the desktop GL driver. This extension makes it easier for bringing mobile OpenGL ES programs to the desktop.

  • Southern Islands Support Will Come To AMDGPU On Linux 4.9

    One month after the first AMDGPU feature pull of new functionality for DRM-Next to in turn land in Linux 4.9, the second feature pull request has now been sent out and it presents experimental Southern Islands (GCN 1.0) support for AMDGPU.

  • Windows-DRI Extension Added For X.Org Server 1.19

    In continuation of yesterday's article about Mesa Gets Improved For Running On Windows With Cygwin, the Windows-DRI extension has landed in the X.Org Server code-base.

    This is about improving the OpenGL/GLX support on Windows in a similar manner to the X.Org Server on Mac OS X, with the primary benefactor to this being applications running under Cygwin. See yesterday's article for some more details.

digiKam 5.2.0 is published...

After a second release 5.1.0 published one month ago, the digiKam team is proud to announce the new release 5.2.0 of digiKam Software Collection. This version introduces a new bugs triage and some fixes following new feedback from end-users. This release introduce also a new red eyes tool which automatize the red-eyes effect reduction process. Faces detection is processed on whole image and a new algorithm written by a Google Summer of Code 2016 student named Omar Amin is dedicated to recognize shapes and try to found eyes with direct flash reflection on retina.

Libreboot Drama Continues, GNU Might Keep The Project

It's been one week since the Libreboot downstream of Coreboot announced it would leave the GNU and denounced the FSF over supposedly a transgendered individual having been fired by the this free software group. Both Richard Stallman and the FSF denounced these claims made by Libreboot maintainer Leah Rowe. Since then, no actual proof has been presented to back up these claims by the Libreboot maintainer but the drama around it has seemingly continued. Waking up this morning, I received an email as part of a long email chain from Leah Rowe about how the "GNU project refuses to let go of libreboot" and she wrote, "GNU project has told me that they will not allow libreboot to leave GNU. This is quite possibly the biggest insult imaginable, considering what has happened." Read more
