  • 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.

Security: Updates, NewEgg Breach, "Master Password" and CLIP OS

  • Security updates for Thursday
  • NewEgg cracked in breach, hosted card-stealing code within its own checkout

    The popular computer and electronics Web retailer NewEgg has apparently been hit by the same payment-data-stealing attackers who targeted TicketMaster UK and British Airways. The attackers, referred to by researchers as Magecart, managed to inject 15 lines of JavaScript into NewEgg's webstore checkout that forwarded credit card and other data to a server with a domain name that made it look like part of NewEgg's Web infrastructure. It appears that all Web transactions over the past month were affected by the breach.

  • "Master Password" Is A Password Manager Alternative That Doesn't Store Passwords
    Master Password is a different way of using passwords. Instead of the "know one password, save all others somewhere" way of managing passwords used by regular password managers, Master Password's approach is "know one password, generate all the others".
  • French cyber-security agency open-sources CLIP OS, a security hardened OS
    The National Cybersecurity Agency of France, also known as ANSSI (Agence Nationale de la Sécurité des Systèmes d'Information), has open-sourced CLIP OS, an in-house operating system its engineers had developed to address the needs of the French government administration. In a press release, ANSSI described CLIP OS as a "Linux-based operating system [that] incorporates a set of security mechanisms that give it a very high level of resistance to malicious code and allow it to protect sensitive information."

What Apps Can You Actually Run on Linux?

Most Linux distributions include Mozilla Firefox as the default web browser. Google also offers an official version of Google Chrome for Linux, and you can even get an “unbranded” open-source version of Chrome named Chromium. Pretty much everything inside your web browser should “just work” in Linux. Netflix now works normally in both Firefox and Chrome on Linux thanks to added support for its DRM. Adobe Flash has become less common on the web but is also available for Linux. It’s included with Chrome, just like on Windows, and you can install it separately for Firefox or Chromium. Linux doesn’t support some older browser plug-ins like Silverlight, but those are no longer widely used on the web. As the desktop PC world has shifted more and more to online, web-based software, Linux has become easier to use. If an application you want to run has a web version, you can use it on Linux.

Nouveau and NVIDIA News

  • Nouveau Developers Begin Reverse-Engineering NVIDIA Turing Driver Support
    The NVIDIA GeForce RTX 2080 graphics cards are only officially beginning to ship today, but at least one independent Nouveau developer already has his hands on the hardware and beginning to work on the clean-room, driver reverse-engineering process in order to eventually get open-source "Nouveau" driver support working.
  • NVIDIA CUDA 10 Officially Released With Turing Support, nvJPEG, CUDA-Vulkan
    Coinciding with the debut of the GeForce RTX 2080 series line-up is now the official release of CUDA 10.0. CUDA 10.0.130 is now official after being announced back at SIGGRAPH. This NVIDIA compute architecture update provides Turing GPU support and its Tensor Cores, NVSwitch Fabric support, nvJPEG as a new library for JPEG processing, various performance tuning for its expansive library set, a new async task-graph programming model, interoperability improvements with Vulkan and D3D12, and new developer tools.
  • NVIDIA have released the 410.57 driver as well as a 396.54.06 Vulkan beta driver to help DXVK
    Along with the release of the GeForce RTX 2080 GPU series NVIDIA have put out a new 410.57 driver to support it. Additionally, there's a new Vulkan beta driver which should help DXVK.
  • Help Test Intel+Nvidia Hybrid Graphics GDM3 Fixes In Ubuntu 18.04
    Ubuntu 18.04 shipped with two issues for Intel+Nvidia hybrid graphics users: an increase in power consumption when the discrete GPU is off, and the inability to switch between power profiles with a simple logout (a restart is currently required). These issues are caused by changes in logind, Nvidia drivers packaging (which is now more granular), and the migration from LightDM to GDM3, and they were fixed in Ubuntu 18.10 Cosmic Cuttlefish.
