  • 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.

Debian and Ubuntu Leftovers

  • Debian package depicts 'Tux the penguin' with sheep in intimate ASCII
    A Debian software package containing an "ASCII representation of zoophilia" has been installed automatically on some users' machines. According to a bug report, Debian user Felicia Hummel installed a package called "cowsay", which turns text into ASCII art of cows (or other animals) with speech or thought balloons. But with default settings of "install suggests" enabled, a controversial second "recommends" package called "cowsay-off" was also installed.

  • Late Post For Ubuntu Community Appreciation Day 2017
    I am also very thankful for LaTeX2e and Tex Live. It has been a great thing to have to prepare devotional materials for church. I am thankful for the MOTU folks maintaining Gummi which is the editor I use on Xubuntu. Xubuntu is what I run on my laptop that goes many places with me. Tex Live is run both on the laptop and on the Raspberry Pi 2 at home.

Running Radeon RX Vega On Linux 4.15, NVIDIA/Radeon Benchmarks

With AMDGPU DC having been merged a few days ago for the Linux 4.15 merge window, it's now possible to run the Radeon RX Vega graphics cards with display support using the mainline kernel without having to resort to using a patched/third-party kernel build or using the AMDGPU-PRO hybrid driver. Here are some tests I have carried out with the Radeon RX Vega 56, RX Vega 64, and other graphics cards from Linux 4.15 Git compared to a few NVIDIA GPUs.
