  • Next steps for Gmane

    We’ve rebuilt the storage system using ElasticSearch as the document store. We have used it for many projects and have nothing but a good. The site is currently a mixture of Python and PHP, the priority has been given to get the original functionality back in place; then work with the community to decide which of the Gmane interfaces are relevant and what we need to change to bring it up-to-date.

    We’ll do our utmost to continue in Lars’ footsteps, his hardwork and dedication to maintain this valuable Internet resource.

    Thank you Lars for the hardwork that you’ve put into Gmane over the past nearly two decades, all of the Gmane users are greatful to you!

  • Audio workshop accepted for Linux Plumbers Conference and Kernel Summit

    Audio is an increasingly important component of the Linux plumbing, given increased use of Linux for media workloads and of the Linux kernel for smartphones. Topics include low-latency audio, use of the clock API, propagating digital configuration through dynamic audio power management (DAPM), integration of HDA and ASoC, SoundWire ALSA use-case managemer (UCM) scalability, standardizing HDMI and DisplayPort interfaces, Media Controller API integration, and a number of topics relating to the multiple userspace users of Linux-kernel audio, including Android and ChromeOS as well as the various desktop-oriented Linux distributions.

  • Mainline Explicit Fencing – part 1
  • Improved Tear-Free Rendering For Radeon DDX With PRIME

    For those making use of the xf86-video-ati DDX driver in a PRIME-capable system with Radeon GPU, there's more effective tear-free rendering support with the latest development code.

  • A Mesa Fix Lands To Take Care Of The R9 290 Issue, Intel/Radeon Performance Problems

    A fix landed in Mesa Git today that should address various performance issues people have been seeing in different rare setups. The fix mostly seems to be for Radeon/Intel users seeing low performance recently with glxgears but also appears to help those affected by the much talked about R9 290 regression.

    The fix by Michel Dänzer is loader/dri3: Always use at least two back buffers. Michel commented on the simple change, "This can make a significant difference for performance with some extreme test cases such as vblank_mode=0 glxgears."

  • RADV Radeon Vulkan Driver One Step Closer To Being Merged In Mesa

    While the ultimate vision of the open-source Radeon Vulkan driver isn't yet clear with RADV being the front-runner so far as the community-based driver while AMD has yet to open up their official Vulkan driver and there's been few remarks about RADV from AMD employees (aside from John Bridgman in our forums), RADV inched forward today in moving closer to being merged in mainline Mesa.

  • libinput and the Lenovo T450 and T460 series touchpads

    I'm using T450 and T460 as reference but this affects all laptops from the Lenovo *50 and *60 series. The Lenovo T450 and T460 have the same touchpad hardware, but unfortunately it suffers from what is probably a firmware issue. On really slow movements, the pointer has a halting motion. That effect disappears when the finger moves faster.

  • RadeonSI Gets Another OpenGL 4.5 Extension: ARB_cull_distance
  • GCN 1.0 / Southern Islands On AMDGPU Takes Another Step Forward
  • Testing The Open-Source "RADV" Radeon Vulkan Driver vs. AMDGPU-PRO

    With word coming out last week that the RADV open-source Vulkan driver can now render Dota 2 correctly, I've been running some tests the past few days of this RADV Vulkan driver compared to AMD's official (but currently closed-source) Vulkan driver bundled with the AMDGPU-PRO Vulkan driver.

  • Keyboard Grabbing Protocol Proposed For Wayland
  • Wayland 1.12 Beta Released

    Bryce Harrington announced the release today of Wayland 1.12 beta and the associated Wayland compositor update.

    Ahead of next month's official Wayland/Weston 1.12 debut, version 1.11.92 was released today. The Wayland 1.12 beta has no new changes over the earlier alpha while Weston has some shell fixes, dropping shell_interface from libweston, and a DRM compositor change. The bare release announcements can be found here.

  • New xserver driver sort order - evdev < libinput < (synaptics|wacom|...)

    In the X server, the input driver assignment is handled by xorg.conf.d snippets. Each driver assigns itself to the type of devices it can handle and the driver that actually loaded is simply the one that sorts last. Historically, we've had the evdev driver sort low and assign itself to everything. synaptics, wacom and the other few drivers that matter sorted higher than evdev and thus assigned themselves to the respective device.

    When xf86-input-libinput first came out 2 years ago, we used a higher sort order than all other drivers to assign it to (almost) all devices. This was of course intentional because we believe that libinput is the best input stack around, the odd bug non-withstanding. Now it has matured a fair bit and we had a lot more exposure to various types of hardware. We've been quirking and fixing things like crazy and libinput is much better for it.

Windows 10 vs. Linux Radeon Software Performance, Including AMDGPU-PRO & RadeonSI

Filed under
Graphics/Benchmarks

As alluded to earlier and on Twitter, the past few days I have been working on a fresh Windows 10 vs. Ubuntu Linux graphics/gaming performance comparison. This time it's looking at the latest Radeon performance using an R9 Fury and RX 480. Tests on Windows were obviously done with Radeon Software Crimson Edition while under Linux were the two latest AMD/RTG Linux driver options: the hybrid AMDGPU-PRO driver and the fully open-source driver via Linux 4.8 and Mesa 12.1-dev.

Unimpressed with Ubuntu 16.10? Yakkety Yak... don't talk back

Before I dive into what's new in Ubuntu 16.10, called Yakkety Yak, let's just get this sentence out of the way: Ubuntu 16.10 will not feature Unity 8 or the new Mir display server. I believe that's the seventh time I've written that since Unity 8 was announced and here we are on the second beta for 16.10. Maybe that's why they named it Unity 8. Whatever the case, Unity 8 is available for testing if you'd like to try it. So far I haven't managed to get it working on any of the hardware I use, which goes a long way to explaining why it's not part of Ubuntu proper yet. Read more

Reiser4 Implements Mirror & Failover Support

Edward Shishkin, one of the last remaining Reiser4 developers and the one who has been leading this out-of-tree file-system the past few years, has implemented logical volumes support with support for mirrors (in effect, RAID 0) and failover support at the file-system level. Shishkin quietly announced on Sunday, "Reiser4 will support logical (compound) volumes. For now we have implemented the simplest ones - mirrors. As a supplement to existing checksums it will provide a failover - an important feature, which will reduce number of cases when your volume needs to be repaired by fsck." Read more

Exactly What Is OpenStack? Red Hat's Rich Bowen Explains

You've probably heard of OpenStack. It's in the tech news a lot, and it's an important open source project. But what exactly is it, and what is it for? Rich Bowen of Red Hat provided a high-level view of OpenStack as a software project, an open source foundation, and a community of organizations in his talk at LinuxCon North America. OpenStack is a software stack that went from small to industry darling at warp speed. It has three major components: The compute service runs the virtual machines (VMs), and it has a networking service and a storage service, plus a dashboard to run everything. OpenStack is only six years old, and was born as a solution devised by Rackspace and NASA to solve a specific problem. Read more

Linux Foundation Certified System Administrator: Muneeb Kalathil

I started using Linux when I was in school. But at that point, I was limited to Installation and running a few commands. I really started learning and growing my interest in Linux while I was working on my degree in Computer Applications. My first distribution was Red Hat CentOS. I spent many hours learning Linux and enjoyed it. Read more
