  • NVIDIA Pushes Out CUDA 9.1 With Compiler Optimizations, Volta Enhancements & More

    AMD isn't the only one busy with GPU software updates today but NVIDIA has issued CUDA 9.1 as their first feature update to the CUDA 9 compute platform.

  • Happy Holidays: AMD Finally Pushing Out Open-Source Vulkan Driver

    Ahead of the Vulkan 1.0 debut nearly two years ago, we heard that for AMD's Vulkan Linux driver it was initially going to be closed-source and would then be open-sourced once ready. At the time it sounded like something that would be opened up six months or so, but finally that milestone is being reached! Ahead of Christmas, AMD is publishing the source code to their official Vulkan Linux driver.

  • The Feature Differences Now Between AMD's Two OpenGL & Two Vulkan Linux Drivers

    For modern AMD graphics cards there are two OpenGL drivers and two Vulkan drivers available to Linux users/gamers that support the same modern AMD GPUs, not counting the older AMD Linux drivers, etc. Here's a rundown now on how those drivers compare.

    With AMDGPU-PRO 17.50 now allowing you to mix and match driver components and AMD finally open-sourcing their official Vulkan driver, the scene may be even more confusing about which AMD Linux driver(s) to use depending upon your use-case.

  • AMDGPU-PRO 17.50 Now Bundles Open-Source Components, Lets You Mix & Match Drivers

    There's more Radeon Linux excitement today beyond AMD finally open-sourcing their Vulkan driver. Coming out today is the AMDGPU-PRO 17.50 driver that bundles in the open-source RADV and RadeonSI drivers too, in letting you "mix and match" the driver components you want for your system.

  • AMD Moving Forward In Their RadeonSI Support For ARB_gl_spirv

    AMD open-source developer Nicolai Hähnle has spent the past few months working on the ARB_gl_spirv extension as mandated by OpenGL 4.6. Some of the prep work for supporting that extension has landed in Mesa 17.4-dev Git.

    ARB_gl_spirv is about bringing SPIR-V support to OpenGL drivers, the IR shared by Vulkan and OpenCL 2.1+. ARB_gl_spirv allows for loading SPIR-V modules into OpenGL programs and allows for GLSL to be a source language in creating SPIR-V modules. This is basically for creating better interoperability between OpenGL and Vulkan/SPIR-V.

  • Mesa Glthread Gets Adds Another Game, AMDGPU Winsys Gets Performance Workaround

    This week has started off to being another busy time in Mesa Git just ahead of the holidays.

    First up, Mount & Blade: Warband is the latest game to be white-listed by the Mesa glthread functionality for enabling OpenGL threading on this Steam Linux game. Mount & Blade: Warband was actually whitelisted back in July but then disabled a few days later as it turned out not to be working.

  • VESA Rolls Out DisplayHDR As Its Latest Standard

    VESA has rolled out DisplayHDR 1.0 as its newest standard. As implied by the name, the standard is in regards to specifying HDR (High Dynamic Range) quality for displays.

  • VC5 OpenGL & Vulkan Driver Advancing

    Broadcom developer Eric Anholt has offered an update on the state of the VC5 Gallium3D driver for OpenGL support as well as the work being done on the "BCMV" Vulkan driver. Additionally, the VC4 Gallium3D driver for existing Raspberry Pi devices continues to get better.

  • Initial Tessellation Shader Support For RadeonSI NIR

    The RadeonSI Gallium3D driver's NIR back-end is moving one step closer to feature parity with the existing OpenGL capabilities of this AMD GCN graphics driver.

    Timothy Arceri working for Valve has been focusing on the NIR back-end recently for RadeonSI. This NIR intermediate representation handling is being driven in order to add SPIR-V ingestion support to RadeonSI with code sharing for RADV's existing NIR-based infrastructure.

Is PowerTop / TLP Still Useful To Save Power On Linux Laptops?

Filed under
Graphics/Benchmarks

This system was running Ubuntu 17.10 and the configurations tested included:

- Ubuntu 17.10 in a "stock" or "out of the box" experience when using its Linux 4.13 kernel, GNOME Shell 3.26.1 with Wayland, and Mesa 17.2.2 atop an EXT4 file-system.

- Upgrading the Ubuntu 17.10 system to Linux 4.15 Git for showing the power consumption when using the very latest kernel cycle.

- This Ubuntu 17.10 + Linux 4.15 system then with Intel PowerTop installed and changing all the tunables to their "good" values for maximum power-savings.

- Installing TLP and using its default power-saving options.

Filed under
Graphics/Benchmarks

Keith Packard has sent out his latest X.Org Server side patches for the improvements he's been working on the past year for improving the SteamVR / VR HMD support on the Linux desktop.

Keith sent out the latest patches for adding RandR 1.6 leases support. These have been re-based against the latest X.Org Server Git code and while there was initial DRM leasing in Linux 4.15, Keith says these patches only work against drm-next, which would mean Linux 4.16. These patches do go through and wire up the leasing support with the xf86-video-modesetting DDX driver.

  • A mini-rant on the lack of string slices in C
  • Simplistic programming is underrated

     

    I should explain. It is absolutely true that if you deploy a larger vocabulary, if you use longer, more pompous sentences, many people will think you are smarter. The same is true with programming. If you can cram metaprogramming, pure functional programming, some assembly and a neural network into one program, many programmers will be impressed by your skills.

  • Comparing C, C++ and D performance with a real world project

    Some time ago I wrote a blog post comparing the real world performance of C and C++ by converting Pkg-config from C to C++ and measuring the resulting binaries. This time we ported it to D and running the same tests.

Power of Unikernels and Linux Graphics

  • Unikraft: Unleashing the Power of Unikernels

     The team at NEC Laboratories Europe spent quite a bit of time over the last few years developing unikernels – specialized virtual machine images targeting specific applications. This technology is fascinating to us because of its fantastic performance benefits: tiny memory footprints (hundreds of KBs or a few MBs), boot times compared to those of processes or throughput in the range of 10-40 Gb/s, among many other attributes. Specific metrics can be found in these articles: “My VM is Lighter (and Safer) than your Container,” “Unikernels Everywhere: The Case for Elastic CDNs,” and “ClickOS and the Art of Network Function Virtualization.”

    The potential of unikernels is great (as you can see from the work above), but there hasn’t been a massive adoption of unikernels. Why? Development time.  For example, developing Minipython, a MicroPython unikernel, took the better part of three months to put together and test. ClickOS, a unikernel for NFV, was the result of a couple of years of work.

  • First Batch Of AMDGPU Changes For Linux 4.16: DC Multi-Display Sync, Vega Tuning

    Alex Deucher of AMD sent in today their first batch of feature updates for Radeon/AMDGPU/TTM feature code for DRM-Next, which has already been queued, and will in turn land next year with the Linux 4.16 kernel.

  • Samsung Improving Cairo's OpenGL ES 3.x Support, May Eye Vulkan In Future

    Back in September there were developers from Samsung's Open-Source Group adding initial OpenGL ES 3.0 support to Cairo. The GLESv3 upbringing in Cairo is still ongoing and not yet fully vetted, but Bryce Harrington of Samsung OSG has now blogged about this effort.

    While there is the initial support for creating an OpenGL ES 3.0 context with Cairo, as Bryce explains in his new blog post, the work on GLES 3.0 for Cairo isn't complete. Additional code is still to be written to leverage new GLES3 functionality and they originally started writing this code for their Tizen platform.

  • Mining cryptocurrency with Raspberry Pi and Storj
    I'm always looking for ways to map hot technologies to fun, educational classroom use. One of the most interesting, and potentially disruptive, technologies over the past few years is cryptocurrencies. In the early days, one could profitably mine some of the most popular cryptocurrencies, like Bitcoin, using a home PC. But as cryptocurrency mining has become more popular, thanks in part to dedicated mining hardware, the algorithms governing it have boosted computational complexity, making home PC mining often impractical, unprofitable, and environmentally unwise.

  • What You Need To Know About The Intel Management Engine
    Over the last decade, Intel has been including a tiny little microcontroller inside their CPUs. This microcontroller is connected to everything, and can shuttle data between your hard drive and your network adapter. It’s always on, even when the rest of your computer is off, and with the right software, you can wake it up over a network connection. Parts of this spy chip were included in the silicon at the behest of the NSA. In short, if you were designing a piece of hardware to spy on everyone using an Intel-branded computer, you would come up with something like the Intel Managment Engine. Last week, researchers [Mark Ermolov] and [Maxim Goryachy] presented an exploit at BlackHat Europe allowing for arbitrary code execution on the Intel ME platform. This is only a local attack, one that requires physical access to a machine. The cat is out of the bag, though, and this is the exploit we’ve all been expecting. This is the exploit that forces Intel and OEMs to consider the security implications of the Intel Management Engine. What does this actually mean?
