  • VC5 Gallium3D Driver Close To Merging To Mainline Mesa

    Broadcom's shiny new VC5 Gallium3D driver for supporting more modern graphics on future SoCs is close to merging to mainline Mesa.

    Details on VC5 are still scarce, such as when we'll see this new Broadcom graphics processor in SoCs/devices (hopefully future Raspberry Pis), but Eric Anholt continues developing this driver. VC5 does support OpenGL ES 3.0 and will also eventually be working on OpenCL and Vulkan support.

  • More Vega/GFX9 Fixes Posted For RADV Vulkan Driver

    It's looking like it shouldn't be much longer before David Airlie has the RADV Mesa Vulkan driver working well on AMD's new Radeon RX Vega graphics cards.

  • AMD Ryzen 3 CPUFreq Governor Benchmarks On Linux 4.13

    For those curious about the performance impact of the different CPUFreq governors on a low-end Ryzen 3 processor, here are some benchmarks.

    Using the Linux 4.13 Git kernel atop Ubuntu 17.04 with the AMD Ryzen 3 1200, I tested CPUFreq's ondemand, performance, powersave, schedutil, and conservative governors. As a reminder, Ubuntu defaults to CPUFreq's "ondemand" governor for AMD processors while the Intel CPUs using the P-State driver use "powersave" as their default.

  • XDC2017 To Feature Update On New Memory Allocation API, HDR, GPGPU, GLVND

    There is now less than one month to go until the annual X.Org Developers' Conference kicks off in Mountain View at the Googleplex. As such, the conference program is now filling up with the interesting talks.

    One of the talks we are very much looking forward to is James Jones' update on a new Unix Device Memory Allocation API. NVIDIA has continued working on a new memory allocation API suitable for OpenGL and Vulkan that will hopefully be adopted cross-vendor and end up being used by Wayland compositors rather than relying upon Mesa's GBM. At XDC2017, NVIDIA is expected to present a design proposal and some of their prototype code. NVIDIA also has talks about DeepColor for HDR (High Dynamic Range) monitor support under X11 as well as on GLVND, the OpenGL Vendor Neutral Dispatch Library.

  • VkMark Makes It Easy To Run Small Vulkan Test Cases

    One of the Vulkan open-source projects I have been tracking the past few months has been VkMark and it's now at a stage where it's becoming sufficiently useful for some small Vulkan test-cases / micro-benchmarks.

  • Intel Submits A Final Batch Of Feature Changes For Their DRM Driver In Linux 4.14

    Intel's open-source developers working on the i915 DRM driver have submitted the last of their feature work slated for the upcoming Linux 4.14 kernel by way of DRM-Next.

  • mesa 17.1.7

    Mesa 17.1.7 is now available.

    In this release we have:

    The state tracker received a fix to avoid a crash accessing a null pointer exposed using llvmpipe on Windows.

  • Mesa 17.1.7 Brings Various Fixes For Users Of Stable Open-Source 3D Drivers

    While Mesa 17.2 is right around the corner, for those sticking to the vetted stable Mesa releases, the 17.1.7 point release is now available.

Kernel and Graphics: Android Kernels, Mesa, and Vulkan 1.0.59

  • Android kernels: does upstream matter?

    There is this false narrative floating around in the dev community on how upstreaming breaks drivers and OEM code. Upstreaming breaking drivers and OEM code is not universally true- in contrast, it defies the very definition of a stable kernel.

    You see, each and every Android device out there runs a version of the Linux Kernel– and it doesn’t have to be the latest version all the time.

  • Mesa 17.2-RC5 Released, Final Should Come Within One Week

    The fifth and final planned release candidate of Mesa 17.2 is now available for testing.

  • Vulkan 1.0.59 Released With Shader Stencil Export

    Vulkan 1.0.59 is now available this weekend as the latest minor update to this high-performance graphics API.

    As usual, the bulk of this Vulkan 1.0.x point release is made up of document clarification/fixes to the text. Of those changes, nothing too notable stands out for Vulkan 1.0.59 but there is one new extension.

Ryzen 3 Linux Gaming Benchmarks: NVIDIA vs. AMD Radeon

Filed under
Graphics/Benchmarks

This week I posted some fresh OpenGL vs. Vulkan benchmarks on the AMD Ryzen 3 while for this weekend article are some more Linux gaming benchmarks from the budget-friendly Ryzen 3 1200 and Ryzen 3 1300X processors.

On the Ryzen 3 1200 and Ryzen 3 1300X, NVIDIA's GeForce GTX 1050 and GTX 1060 graphics cards were tested while on the Radeon side was the RX 560 and RX 480 graphics cards. The NVIDIA driver release used was the 384.59 driver while on the Radeon side was Linux 4.13 AMDGPU DRM plus Mesa 17.3-dev Git built against LLVM 6.0 SVN using the Padoka PPA.

  • Vega 10 Huge Page Support, Lower CS Overhead For AMDGPU In Linux 4.14

    With this weekend marking the ending of David Airlie accepting new feature material for DRM-Next to in turn land in the Linux 4.14 cycle in a few weeks, there's a rush by Direct Rendering Manager driver maintainers to submit the last of their new feature work of changes they want in this next kernel release.

  • [Video] [ReactOS] Introducing Kaasimir - GPU Testing Made Simple

    It makes use of QEMU, PCI-Express Passthrough, and eRIC Express KVM-over-IP cards to provide ReactOS VMs with real GPUs attached. Testing a GPU driver in ReactOS is now as easy as testing ReactOS in a VM.

  • End in Sight

    The last week of GSoC 2017 is about to begin. My project is in a pretty good state I would say: I have created a big solution for the Xwayland Present support, which is integrated firmly and not just attached to the main code path like an afterthought. But there are still some issues to sort out. Especially the correct cleanup of objects is difficult. That’s only a problem with sub-surfaces though. So, if I’m not able to solve these issues in the next few days I’ll just allow full window flips. This would still include all full screen windows and for example also the Steam client as it’s directly rendering its full windows without usage of the compositor.

OpenGL vs. Vulkan On The AMD Ryzen 3

Filed under
Graphics/Benchmarks

We have previously looked at Vulkan vs. OpenGL Linux game CPU core scaling and Linux game scaling across multiple CPUs but at the time did not have a Ryzen 3 system. Now having Ryzen 3 Linux box, here is a look at how the Vulkan versus OpenGL performance compares on the low-end processor. As well, it's a fresh look at the NVIDIA vs. RadeonSI/RADV performance.

Athlon II X3 vs. Ryzen 3: How AMD's Performance Has Evolved & Performance-Per-Watt

Filed under
Graphics/Benchmarks

Noticing I had an AMD Athlon II X3 425 system still racked up and hadn't been powered on in a long time, I decided to decomission it, but not before running some final benchmarks on that system. Having the recent AMD Ryzen 3 1200 / 1300X CPUs I decided it would make for an interesting comparison how the old Athlon II X3 compares to AMD's low-end CPU of today, the Ryzen 3 processors based on Zen. Here are those benchmarks that also include performance-per-Watt and overall AC system power consumption numbers.

  • Navigating Cloud Foundry

    This open source platform-as-a-service cloud platform bridges the gap between legacy applications and cloud services.

    For all the talk about the cloud, many applications continue to run on traditional servers. Hybrid architectures are sometimes the right option, but if you want to move corporate applications onto the Internet, you don’t want to start from scratch. Cloud Foundry, a platform-as-a-service (PaaS) cloud platform, enables enterprises to move older software to the cloud and build new cloud-centric programs using familiar tools and programming languages.

  • HMM Revised Its 25th Time, Seeking Inclusion In Linux 4.14

    Jerome Glisse of Red Hat has published his 25th revision to the Heterogeneous Memory Management (HMM) patch series. HMM is about allowing a process address space to be mirrored and for system memory to be transparently used by any device process.

    With HMM v25, there are more code comments and documentations, fixes to the code, merging the HMM-CDM patches into this patch series, and other improvements.

  • Radeon X.Org Driver Gets Fixed Up To Always Allow Page-Flipping With TearFree

    It's fairly rare these days seeing improvements to the xf86-video-ati DDX: the driver for those running a pre-AMDGPU (GCN 1.2) graphics card with this driver paired with Radeon DRM and not using the generic xf86-video-modesetting driver instead. But if you are using xf86-video-ati and use the "TearFree" feature to try to avoid screen tearing, a number of patches landed today.

    Michel Dänzer of AMD landed a handful of patches to the xf86-video-ati Git repository today for the Radeon DDX. Notably the patches make for always allowing DRI2 page-flipping to be used with TearFree and the same goes for DRI Present page-flipping with the TearFree option. Long story short, page-flipping should now always work in the TearFree mode.

  • NVIDIA Releases Vulkan 381.26.13 Beta Linux Driver

    NVIDIA's driver team has today released new Vulkan beta drivers for both Windows and Linux.

    The new NVIDIA Linux Vulkan beta is versioned at 381.26.13, so still not yet re-based to the current 384 series, but these changes should end up being merged for their next feature series to mainline.

Security: WPA2, RSA/TPM, and Microsoft Breach

  • Google and Apple yet to fix Wi-Fi hole in a billion devices

    The WPA2 security protocol has been a mandatory requirement for all devices using the Wi-Fi protocol since 2006, which translates into billions of laptops, mobiles and routers. The weakness identified by Mathy Vanhoef, a digital security researcher at the Catholic University of Leuven (KUL) in Belgium, lies in the way devices running WPA2 encrypt information.

  • The Flawed System Behind the Krack Wi-Fi Meltdown

    No software is perfect. Bugs are inevitable now and then. But experts say that software standards that impact millions of devices are too often developed behind closed doors, making it difficult for the broader security community to assess potential flaws and vulnerabilities early on. They can lack full documentation even months or years after their release.

  • Factorization Flaw in TPM Chips Makes Attacks on RSA Private Keys Feasible

    Security experts say the bug has been present since 2012 and found specifically in the Infineon’s Trusted Platform Module used on a large number of business-class HP, Lenovo and Fijitsu computers, Google Chromebooks as well as routers and IoT devices.

  • ROCA: RSA encryption key flaw puts 'millions' of devices at risk

    This results in cyber criminals computing the private part of an RSA key and affects chips manufactured from 2012 onwards, which are now commonplace in the industry.

  • Infineon RSA Key Generation Issue

    Yubico estimates that approximately 2% of YubiKey customers utilize the functionality affected by this issue. We have addressed this issue in all shipments of YubiKey 4, YubiKey 4 Nano, and YubiKey 4C, since June 6, 2017.
