  • Marek Has Been Taking To AMDGPU LLVM Optimizations

    Well known AMD open-source driver developer Marek Olšák has ruthlessly been optimizing the Radeon Mesa driver stack for years. With RadeonSI getting fine-tuned and already largely outperforming the AMDGPU-PRO OpenGL driver and most of the big ticket improvements complete, it appears his latest focus is on further optimizing the AMDGPU LLVM compiler back-end.

    This AMDGPU LLVM compiler back-end is what's used by RadeonSI but is also leveraged by the RADV Vulkan driver, among other potential use-cases. Lately Marek has been filing patches for optimizing the instructions generated during the shader compilation process.

  • FFmpeg Expands Its NVDEC CUDA-Accelerated Video Decoding

    A few days back I wrote about FFmpeg picking up NVDEC-accelerated H.264 video decoding and since then more FFmpeg improvements have landed.

    As mentioned in the earlier article, NVDEC is the newer NVIDIA video decoding interface that is succeeding their Linux-specific VDPAU in favor of the cross-platform, CUDA-based NVIDIA Video Codec SDK. There's also NVENC on the video encode side, while the recent FFmpeg work has been focused on the NVDEC GPU-based video decoding.

  • Intel Batch Buffer Logger Updated For Mesa

    Intel's Kevin Rogovin has been working on a "BatchBuffer Logger" for the Intel graphics driver that offers some useful possibilities for assisting in debugging/analyzing problems or performance penalties facing game/application developers.

    The BatchBuffer Logger is designed to allow correlating API calls to data that in turn is added to a batch buffer for execution by the Intel graphics processor. The logger additionally keeps precise track of the GPU state and can report various metrics associated with each API call.

  • Feral Interactive continues to contribute to Mesa as one of its developers gets commit privileges

    Alex Smith of Feral has been granted the right to push code into Mesa, a continuing sign of the commitment of Feral to Mesa and Vulkan.

    In this recent exchange Feral dev and active Mesa contributor, Alex Smith, has asked and gotten permission to create an account to directly access the Mesa driver’s git. His stated purpose is to provide fixes for Vulkan drivers, so we can take that as a sign that Feral is pretty serious at not only contributing to the open source Mesa project but also at using the Vulkan API in their current and future ports.

  • Valve has added 11 new currencies to the Steam Store

    Recent changes to the Steam Store have seen the addition of more local currencies for customers in different regions. Expect to get more bang for your Peso or Dinar.

    Originally tweeted by the excellent SteamDB, it would seem that customers in different regions will be able to buy from the Steam Store using their local currency. This usually means lower prices and no fiddling about with conversion rates for currency and prices are also adjusted for regional standards. The changes went live earlier and users in the affected countries have gotten emails telling them about the new changes to the Steam Store.

  • Trüberbrook, a beautiful adventure game with Linux support, is on Kickstarter

    This story-driven adventure game set in 1960s Germany places you in the role of a young scientist who finds himself having to save the world.

Programming: GNU Nano, Software Engineering Talent Shortage, HHVM (PHP)

  • GNU Nano Latest Version 2.9.0
    GNU nano 2.9.0 "Eta" introduces the ability to record and replay keystrokes (M-: to start and stop recording, M-; to play the macro back), makes ^Q and ^S do something useful by default (^Q starts a backward search, and ^S saves the current file), changes ^W to start always a forward search, shows the number of open buffers (when more than one) in the title bar, no longer asks to press Enter when there are errors in an rc file, retires the options '--quiet' and 'set quiet' and 'set backwards', makes indenting and unindenting undoable, will look in $XDG_CONFIG_HOME for a nanorc file and in $XDG_DATA_HOME for the history files, adds a history stack for executed commands (^R^X), does not overwrite the position-history file of another nano, and fixes a score of tiny bugs.
  • GNU Nano Text Editor Can Now Record & Replay Keystrokes
    GNU Nano 2.9 is now available as the latest feature release of this popular CLI text editor and it's bringing several new capabilities. First up, GNU Nano 2.9 has the ability to record and replay keystrokes within the text editor. M-: is used to start/stop the keystroke recording session while M-; is used to playback the macro / recorded keystrokes.
  • 2018's Software Engineering Talent Shortage— It’s quality, not just quantity

    The software engineering shortage is not a lack of individuals calling themselves “engineers”, the shortage is one of quality — a lack of well-studied, experienced engineers with a formal and deep understanding of software engineering.

  • HHVM 3.23
    HHVM 3.23 is released! This release contains new features, bug fixes, performance improvements, and supporting work for future improvements. Packages have been published in the usual places, however we have rotated the GPG key used to sign packages; see the installation instructions for more information.
  • Facebook Releases HHVM 3.23 With OpenSSL 1.1 Support, Experimental Bytecode Emitter
    HHVM 3.23 has been released as their high performance virtual machine for powering their Hack programming language and current PHP support. As mentioned back in September though, Facebook will stop focusing on PHP 7 compatibility in favor of driving their own Hack programming language forward. It's after their next release, HHVM 3.24, in early 2018 they will stop their commitment to supporting PHP5 features and at the same time not focus on PHP7 support. Due to the advancements made by upstream PHP on improving their performance, etc, Facebook is diverting their attention to instead just bolstering Hack and thus overtime the PHP support within HHVM will degrade.

Linux 4.14 File-System Benchmarks: Btrfs, EXT4, F2FS, XFS

Our latest Linux file-system benchmarking is looking at the performance of the mainline Btrfs, EXT4, F2FS, and XFS file-systems on the Linux 4.14 kernel compared to 4.13 and 4.12. In looking to see how the file-system/disk performance has changed if at all under the newly released Linux 4.14 kernel, I carried out some 4.12/4.13/4.14 benchmarks using Btrfs/EXT4/F2FS/XFS while freshly formatting the drive each time and using the default mount options.

Canonical Releases Snapcraft 2.35 with Support for Ubuntu 14.04 LTS and Solus

Snapcraft 2.35 comes approximately two months after the September release of Snapcraft 2.34, and it's a major update that finally adds support for the Ubuntu 14.04 LTS (Trusty Tahr) operating system series, which is maintained by Canonical for five years, until April 2019. Ubuntu 14.04 LTS support in Snapcraft is particularly important for running Snaps based on ROS (Robot Operating System) Indigo, which is based on this LTS Ubuntu release. In addition, Snapcraft also appears to have received support for the Solus Linux-based operating system. Read more
