  • 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.

Security: Updates, First PGPainless Release, and 'The Cloud'

  • Security updates for Thursday
  • First PGPainless Release!
    PGPainless 0.0.1-alpha1 is the first non-snapshot release and is available from maven central. It was an interesting experience to go through the process of creating a release and I’m looking forward to have many more releases in the future :) The current release contains a workaround for the bug I described in an earlier blog post. The issue was, that bouncycastle wouldn’t mark the public sub keys of a secret key ring as sub keys, which results in loss of keys if the user tries to create a public key ring from the exported public keys. My workaround fixes the issue by iterating through all sub keys of an existing key ring and converting the key packages of subkeys to subkey packages. The code is also available as a gist.
  • Thousands of US voters' data exposed by robocall firm
    A Virginia-based political campaign and robocalling company, which claims it can "reach thousands of voters instantly," left a huge batch of files containing hundreds of thousands of voter records on a public and exposed Amazon S3 bucket that anyone could access without a password.  The bucket contained close to 2,600 files, including spreadsheets and audio recordings, for several US political campaigns. Kromtech Security's Bob Diachenko, who discovered the exposed data and blogged his findings, shared prior to publication several screenshots of data, packed with voters' full names, home addresses, and political affiliations.
  • Another Day, Another Pile Of Voter Data Left Laying Around On A Public Server
    Leaving private voter or customer data easily accessible on a public-facing server is the hot new fashion trend. You'll recall that it's a problem that has plagued the Defense Department, GOP data firm Deep Root Analytics (198 million voter records exposed), Verizon's marketing partners (6 million users impacted), Time Warner Cable (4 million users impacted), and countless other companies or partners that failed to implement even basic security practices. And it's a trend that shows no sign of slowing down despite repeated, similar stories (much of it thanks to analysis by security researcher Chris Vickery). This week yet another pile of private voter data was left publicly accessible for anybody to peruse. According to analysis by Kromtech Security’s Bob Dianchenko, a Virginia-based political consulting and robocalling company by the name of Robocent publicly exposed 2,600 files, including voter file spreadsheets (including voter phone numbers, names, addresses, political affiliations, gender, voting districts and more) and audio recordings for a number of political campaigns.

Canonical/Ubuntu: End of Ubuntu 17.10, Ubuntu Podcast, Snaps Add Flexibility with Tracks and Canonical Needs Help

  • PSA: Support for Ubuntu 17.10 Ends Today
    Ubuntu 17.10 reaches end of life on July 19, 2018 — which if you haven’t checked your calendar recently, is today. If you have thus far managed to resist the temptation to upgrade to a newer release then alas: today is the day when you need to start thinking about it.
  • Ubuntu Podcast from the UK LoCo: S11E19 – Nineteen Minutes - Ubuntu Podcast
    It’s Season 11 Episode 19 of the Ubuntu Podcast! Alan Pope, Mark Johnson and Ryan are connected and speaking to your brain.
  • Snaps Add Flexibility with Tracks
    Snap packages have a rich set of features beyond getting the latest shiny on your Linux distribution. Tracks enable developers to publish multiple supported releases of their application under the same name. With this enabled, a user can switch tracks at any time to install and use an alternate supported relase of software. Within each track are four standard channels named edge, beta, candidate and stable. The channels represent the risk-level users should expect from the snaps within. Edge snaps (typically built from the latest code committed) would be riskier to use than beta releases, which are more risky than stable releases. By default every application has one ‘latest’ track and the four named channels. Developers can optionally choose whether to supplement that with additional tracks. Further the developer can choose which channels to use within those tracks.
  • Canonical Needs Your Help to Test the Improved Ubuntu 18.04.1 Server Installer
    Canonical's Dimitri John Ledkov put out a call for testing for the Ubuntu community to help them test drive the improved Ubuntu Server installer in the upcoming Ubuntu 18.04.1 LTS point release. Ubuntu 18.04.1 LTS, the first of a total of five scheduled point releases of the long-term supported Ubuntu 18.04 LTS (Bionic Beaver) operating system series is about to be released in approximately one week from the moment of writing, on July 26, 2018, with improved and up-to-date core components and apps.
  • Help Test the New Ubuntu Server Installer

  • ROCm 1.8.2 Released For The Open-Source Radeon Linux Compute Stack
    While waiting for the big ROCm 1.9 update, another point release to the ROCm 1.8 series is available for this Radeon Open Compute stack. Earlier this month the AMD developers working on this Linux open-source OpenCL/compute stack pushed out the ROCm 1.8.2 beta while today it was elevated to the stable channel. Details on the ROCm 1.8.2 update are unfortunately light, but based upon user reports, it seems to be able to create a working environment on Ubuntu 18.04 LTS if paired with a newer kernel. But the official Ubuntu 18.04 LTS isn't coming until ROCm 1.9.
  • Raven Ridge APUs Get Minor Performance Boost With Latest RADV Vulkan Driver
    The Raven Ridge Linux support continues to maturing. The latest on these Zen+Vega APUs using the open-source AMD Radeon Linux graphics driver stack should be slightly better performance when using the RADV Vulkan driver. RADV co-founder Bas Nieuwenhuizen landed a number of commits on Wednesday to further enhance this Mesa-based Radeon Vulkan driver. With this latest work, he's now enabled binning and DFSM by default for Raven Ridge hardware. With this being enabled now for Raven, he's found a minor performance in the range of 2~3% for some demos and games tested.
