  • 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.

    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.

Android Leftovers

Report from Debian SnowCamp and a Look at Solyd XK, a Debian-Based Distribution

  • Report from Debian SnowCamp: day 1
  • Report from Debian SnowCamp: day 2
    Of course, we’re still sorely lacking volunteers who would really care about mentors.debian.net; the codebase is a pile of hacks upon hacks upon hacks, all relying on an old version of a deprecated Python web framework. A few attempts have been made at a smooth transition to a more recent framework, without really panning out, mostly for lack of time on the part of the people running the service. I’m still convinced things should restart from scratch, but I don’t currently have the energy or time to drive it… Ugh.
  • Installing Solyd XK, a Debian based Linux distribution : Cooking With Linux
    It's time for some more "Cooking With Linux" without a net, meaning the video you are about to watch was recorded live. Today, I'm going to install a new Linux distribution (new to me, anyhow) called Solyd XK.

Aquaris E4.5 Ubuntu Phone - With Android

I ever so slightly regret the "upgrade" to Android. With a version less than the tablet, the UI changes are extremely noticeable, and the transition isn't as smooth. The device lags, and it just doesn't have enough processing power to give the necessary feel of goodness and elegance. On the other hand, you get tons of native applications that you can actually use, as opposed to the Ubuntu Touch idea. Shame really. For 'tis a compromise. If you ask me, I wholeheartedly embrace the M10 tablet upgrade, but on the phone, you might as well keep Ubuntu unless you need the device for serious use. If it's just an opportunistic call/SMS thing for when abroad and such, or to loan to friends, the original combo is adequate. If you need apps, then Android is the way to go, but do not except any miracles. It won't be speedy, and it won't be too pretty. All in all, an okay player. It is silly attaching sentiments to software or hardware, but I do guess I will fondly remember the Ubuntu phone attempt as a noble idea to make something great and fun. I could have kept the device in its original state, perhaps, but in the end, it would have ended in a pile of ancient stuff you keep around for a decade until you decide you need to throw it away to leave room for fresh memories and less ancient stuff. Having a flawless Android experience would have helped soften the edge, but as it is, it remains the bittersweet attempt at what could have been a revolution. The end.

  • Red Hat Decision Manager 7 Boosts BPM with Low-Code Approach
    Red Hat is perhaps best known for its Enterprise Linux platform, but it has been a player in the Business Process Management (BPM) suite for over a decade too.
