  • Session suspension and restoration protocol
  • A Session Suspension & Restoration Protocol Proposed For Wayland

    KDE Wayland developer Roman Gilg who started contributing to Wayland via last year's Google Summer of Code is proposing a new Wayland protocol for dealing with desktop session suspension and restoration.

    This protocol extension would allow for more efficient support for client session suspension and restoration such as when you are logging out of your desktop session and want the windows restored at next log-in or if you are suspending your system. While Roman Gilg is working on this protocol with his KDE hat on, he has been talking with Sway and GNOME developers too for ensuring this protocol could work out for their needs.

  • RadeonSI Lands OpenGL 3.3 Compatibility Profile Support

    Thanks to work done over the past few months by AMD's Marek Olšák on improving Mesa's OpenGL compatibility profile support and then today carried over the final mile by Valve's Timothy Arceri, Mesa 18.2 now exposes OpenGL 3.3 under the compatibility context.

    Hitting Git tonight is the enabling of the OpenGL 3.3 compatibility profile for RadeonSI.

  • Linux literally loses its Lustre – HPC filesystem ditched in new kernel

    Linux has literally lost its Lustre – the filesystem favoured by HPC types has vanished in the first release candidate of version 4.18 of the Linux kernel.

    Linus Torvalds’ announcement of the new release lauds the fact it’s shrunk markedly, much of which can be attributed to the removal of Lustre.

    “The removal of Lustre may not be all that notable, because it does look like a lot of the development has been happening out of tree, which may be why it never really ended up working as well as people hoped in the staging tree,” Torvalds wrote. “ Greg [ Kroah-Hartman] clearly got pretty frustrated about it, so now it's gone.”

    How frustrated? Kroah-Hartman explained Lustre's omission by saying it has "been in the kernel tree for over 5 years now" but "has not really moved forward into the 'this is in shape to get out of staging' despite many half-completed attempts."

  • Harmonising open source and standards in the telecom world [Ed: Phone surveillance company pays LF and then (mis)appropriates the “Linux” brand to push its “whitepapers” (marketing)]

    Standards have played a major role in telecommunications technology adoption for many years, validating the commercial viability of new technologies, facilitating multi-vendor interoperability, improving product quality, and expediting the introduction of technologies that would otherwise proliferate in a sea of proprietary alternatives.

  • OpenGL Floating Point Textures No Longer Encumbered By Patents, Enabled In Mesa

    Back in 2012 when talking with Gabe Newell of Valve about open-source/Linux challenges one of the topics he was awed about was patents encumbering the open-source graphics driver progress. Six years later, Timothy Arceri working on the Valve Linux graphics driver team has freed Mesa's ARB_texture_float support from being built conditionally due to these patent fears.

  • Vulkan 1.1.78 Released With Various Issues Resolved

    Vulkan 1.1.78 is now available as the newest version of the Vulkan specification.

    The Vulkan 1.1.78 spec update is another fairly small update that doesn't introduce any new VK extensions or any major changes. Vulkan 1.1.78 has minor documentation fixes, resumes publishing of the Vulkan 1.0 + KHR extension documentation, clears up some behavior in some Vulkan usage, and other changes.

  • AMDGPU Performance Tests With New WattMan-Like Settings, Power Capping

    With the recent stable debut of the Linux 4.17 kernel, one of the most common performance test requests coming in has been for checking out the Radeon WattMan-like support that was introduced with the Linux 4.17 AMDGPU code for recent generations of Radeon graphics card. Here are some benchmarks of that and on a somewhat related note also some Linux gaming benchmark results when carrying out some power capping tests to restrict the graphics card to a given Wattage.

  • RISC-V Changes Merged For Linux 4.18, Early Perf Subsystem Work

    Initial RISC-V architecture support was added to the Linux 4.15 kernel and in succeeding kernel releases have been mostly modest updates. With Linux 4.18 the RISC-V changes are on the small side still, but with a few notable additions for this open-source, royalty-free processor ISA.

  • Intel Icelake Bringing New MIPI DSI Controller, Linux Driver Patches Posted

    While Intel Icelake hardware is quite a ways out from making its debut, the open-source Intel Linux developers working on the hardware enablement for its "Gen 11" graphics continue working dilligently on this hardware enablement.

    Preparations for Intel Icelake support began with the Linux 4.17 kernel, have continued with the current 4.18 development cycle, and will continue for the next several cycles as all of the support gets squared away, just not for the graphics hardware.

  • NVIDIA Contributes EGLStreams Improvements For GNOME's Mutter Wayland Support

    GNOME's Mutter Wayland compositor support is among the few Wayland implementations offering support for EGLStreams so it can play along with the approach used by the NVIDIA proprietary driver as an alternative to the GBM API used by the open-source graphics drivers. One of the NVIDIA engineers has just furthered along Mutter's EGLStreams support.

  • Mesa 18.1.2 Released With Several RADV & Intel Driver Fixes

    New Mesa release manager Dylan Baker has issued the second point release of the Mesa 18.1 series.

    Mesa 18.1 has many exciting features and continues to see new bi-weekly point releases until after Mesa 18.2 has been released around the middle of August and then sees its subsequent Mesa 18.2.1 point release before that kills off the 18.1 release stream.

  • Mesa Rolls Out Support For ARB_sample_locations

    Mesa has been plumbed in to support the ARB_sample_locations OpenGL extension and is now exposed with the Nouveau NVC0 Gallium3D driver.

    ARB_sample_locations was part of the "OpenGL 2015" update but hasn't made it into a released version of OpenGL, hence why it wasn't a priority for Mesa developers. But now it's been wired up within core Mesa and is currently flipped on for NVC0 in Mesa 18.2-devel.

  • Mesa's VirGL For OpenGL Within VMs Now Supports Tessellation Shaders

    It was just days ago that the VirGL driver stack -- which is used for supporting OpenGL hardware acceleration within guest VMs that is passed onto the host's driver -- picked up FP64 support while now its latest addition is ARB_tessellation_shader support.

    With the latest Mesa Git and the VirGL renderer library code is updated (as well as your host OpenGL driver supporting GL4), there is now support for tessellation shaders. The support has landed in Mesa 18.2 Git for this popular OpenGL 4.0 feature.

  • The NVIDIA vs. Open-Source Nouveau Linux Driver Benchmarks For Summer 2018

    It has been some months since last delivering any benchmarks of Nouveau, the open-source, community-driven for NVIDIA GPUs. The reason for not having any Nouveau benchmarks recently has largely been due to lack of major progress, at least on the GeForce desktop GPU side, while NVIDIA has continued to contribute on the Tegra side. For those wondering how the current performance is of this driver that started out more than a decade ago via reverse-engineering, here are some benchmarks of the latest open-source Nouveau and NVIDIA Linux graphics drivers on Ubuntu.

  • H.264 Decoding Tackled For Reverse-Engineered "Cedrus" Allwinner Video Decode Driver

    The Bootlin (formerly Free Electrons) developers working on the Cedrus open-source, reverse-engineered Allwinner video decode driver have posted their patches for enabling H.264 video decoding.

    Earlier versions of their Sunxi-Cedrus driver patches had just supported MPEG-2 with other codecs to be tackled, but hitting the kernel mailing list this week were their patches for enabling H.264 decoding on Allwinner hardware.

  • More Vega M Performance Numbers Surfacing, Linux State Looking Good

    The performance of the Intel Core i7-8809G "Kabylake G" processor with onboard Radeon "Vega M" graphics are looking quite good under Linux now that the support has been squared away.

  • Mesa RadeonSI Lands Possible Vega/Raven Performance Improvement

    Earlier this month AMD's Marek Olšák posted RadeonSI patches for a scissor workaround affecting GFX9/Vega GPUs including Raven Ridge, which were based upon a RADV driver workaround already merged that helped affected games by up to ~11%. A revised version of that patch is now in Mesa 18.2 Git.

  • libinput and its device quirks files

    This post does not describe a configuration system. If that's all you care about, read this post here and go be angry at someone else. Anyway, with that out of the way let's get started.

    For a long time, libinput has supported model quirks (first added in Apr 2015). These model quirks are bitflags applied to some devices so we can enable special behaviours in the code. Model flags can be very specific ("this is a Lenovo x230 Touchpad") or generic ("This is a trackball") and it just depends on what the specific behaviour is that we need. The x230 touchpad for example has a custom pointer acceleration but trackballs are marked so they get some config options mice don't have/need.

  • Wayland's Weston 5.0 Moved Up To An August Release

    Following the recent discussions of moving Wayland's Weston compositor to a 4-month release schedule and possibly doing away with time-based Wayland releases itself, Weston 5.0 will now be coming out in August.

    Feature development on Weston is as busy as ever while Wayland (libwayland) is quite mature and not seeing too much churn. Upstream Wayland developers now appear to be in agreement to carrying out the next Weston release at least on a four-month release cycle.

  • Librem 5 progress report #14

    On the nuts and bolts level, our phone shell (phosh) has seen several usability improvements mostly around the lockscreen. One important change is that the lockscreen unlocking has been switched to PAM to better handle the PIN to lock the device. There have also been some additions to the code to better handle multiple outputs (screens). Also, Libhandy is our “handy” UI library for developing GTK+ apps. There has been a recent addition of an arrows widget (HdyArrows) to indicate swiping direction which will be very useful to many applications, especially the lockscreen. Additionally, libhandy has seen some bug fixes and a slight rework of the keyboard handling support. Since graphics are important, we have added Etnaviv support to weston-simple-dmabuf (a Wayland client to test Linux DMA-BUF protocol implementations). We also extended it’s NV12 format support. It’s being used over here to test wlroot’s linux-dmabuf implementation which we wrote a couple of weeks ago. We’d like to especially thank the wlroots and Weston projects for their code reviews, recommendations, and support.

    With Intel's DRM kernel driver now supporting HDCP for High-bandwidth Digital Content Protection with work done by Intel and Google developers, there is now work underway for allowing HDCP to work in a Wayland-based environment.

    As with the work done on the Direct Rendering Manager side, these Wayland patches aren't enforcing any restrictions on users by itself but is simply making the support available should any applications come along that wish to enforce HDCP usage on the Linux desktop.

  • VFIO Adds Sample Mediated Device Display Drivers

  • A Look At How The AMD EPYC Linux Performance Has Evolved Over The Past Year

    This month marks one year since AMD returned to delivering high-performance server CPUs with the debut of their EPYC 7000 series processor line-up. It's been a triumphant period for AMD with the successes over the past year of their EPYC family. Over the past year, the Linux support has continued to improve with several EPYC/Zen CPU optimizations, ongoing Zen compiler tuning, CPU temperature monitoring support within the k10temp driver, and general improvements to the Linux kernel that have also helped out EPYC. In this article is a comparison of a "2017" Linux software stack as was common last year to the performance now possible if using the bleeding-edge software components. These Linux benchmarks were done with the EPYC 7351P, 7401P, and 7601 processors.

  • Atari VCS Console Runs a Custom Linux Distro Called “AtariOS”
    Following criticism of its mediocre internal makeup the Ataris VCS console will now ship with 8GB RAM by default, up from the 4GB proposed during the funding push. It’s a decent increase in memory that should help the system cope better with more intensive indie games (don’t expect AAA titles to play nicely on the machine with the middling AMD Bristol Ridge APU).

  • How expensive is globbing for sources in large projects
    Since we have the measurement script, let's use it for something more interesting. Modules are an upcoming C++ feature to increase build times and a ton of other coolness depending on who you ask. The current specification works by having a kind of "module export declaration" at the beginning of source files. The idea is that you first compile those to generate a sort of a module declaration file and then you can start the actual compilation that uses said files. If you thought "waitaminute, that sounds exactly like how FORTRAN is compiled", you are correct. Because of this it has the same problem that you can't compile source files in an arbitrary order, but instead you must first somehow scan them to find out the interdependencies between source (not header) files. In practice what this means is that instead of single-phase compilation all files must be processed twice. All scan operations must be done before any compilation jobs can start because otherwise you might start to compile a file before its dependencies are fully processed. The scanning can be done in one of two ways. Either the build system scans the sources meaning it needs to understand the syntax of source files or the compiler can be invoked in a special preprocessing mode. Note that build systems such as Ninja do not do any such operations by themselves but instead always invoke external processes to do their work.
