Graphics/Benchmarks

With the GCC 7 compiler having entered its stage three, feature development is basically over so it's a great time to begin running more benchmarks of this big compiler update that will be officially released as GCC 7.1.0 in early 2017. Up today are benchmarks of the latest GCC 7.0 development snapshot compared to GCC 6.2 and GCC 5.4 on an Intel Core i7 6800K Broadwell-E system running Ubuntu 16.10.

  • LibRetro's Vulkan PlayStation PSX Renderer Released

    A few days back I wrote about a Vulkan renderer for a PlayStation emulator being worked on and now the code to that Vulkan renderer is publicly available.

    For those wanting to relive some PlayStation One games this week or just looking for a new test case for Vulkan drivers, the Vulkan renderer for the LibRetro Beetle/Mednafen PSX emulator is now available, months after the LibRetro folks made a Vulkan renderer for the Nintendo 64 emulator.

  • Etnaviv DRM Updates Submitted For Linux 4.10

    The Etnaviv DRM-Next pull request is not nearly as exciting as MSM getting Adreno 500 series support, a lot of Intel changes, or the numerous AMDGPU changes, but it's not bad either for a community-driven, reverse-engineered DRM driver for the Vivante graphics cores.

  • Mesa 12.0.4 Being Prepped For Ubuntu 16.10/16.04

    Ubuntu is preparing Mesa 12.0.4 for Ubuntu Xenial and Yakkety users. It's not as great as Mesa 13, but at least there are some important fixes back-ported.

    Mesa 12.0.4 is exciting for dozens of bug fixes, including the work to offer better RadeonSI performance. But with Mesa 12.0.4 you don't have the RADV Vulkan driver, OpenGL 4.5, or the other exciting Mesa 13 work.

Clear Linux With Mesa 13 Is A Strong Match For Intel Linux Performance

Filed under
Graphics/Benchmarks

When benchmarking Intel's Clear Linux distribution earlier this year we found its Intel graphics performance to be quite good and slightly faster than other Linux distributions even when Clear was using an older version of Mesa. Now with Clear Linux having switched to Mesa 13, I decided to run some fresh Intel OpenGL benchmarks on it compared to other distributions.

PTS: PHP 7.1 vs. PHP 7.0 vs. HHVM Benchmarks

Filed under
Development
Graphics/Benchmarks

With today's PHP 7.1 release, performance isn't highlighted as much as language improvements to this first major update to PHP7, but I decided to run some PHP 7.1, PHP 7.0, PHP 5.6, PHP 5.5, and HHVM benchmarks of our open-source Phoronix Test Suite code-base.

These self-tests of the Phoronix Test Suite aren't the conventional PHP workload of just a CMS, blog, or other web application that can be cached, etc, but effectively of a PHP CLI application. So keep this in mind when looking at the results and that your mileage may vary depending upon use-case.

  • Developers' Planned Changes Still Coming To Mesa 13.1 / Mesa 17.0

    Earlier this week I wrote about a release schedule coming out for Mesa 13.1 that culminates with this next big Mesa update being out in February. Some Mesa developers have now shared the work they still hope to see in this next release.

  • Gallium3D Drivers Prepped For EGL_ANDROID_native_fence_sync

    Rob Clark has landed his code for supporting EGL_ANDROID_native_fence_sync in Mesa and his Freedreno Gallium3D driver is the first in-tree Mesa/Gallium3D driver to support the native fence FD support, even beating out the Intel driver.

  • Intel Publishes Renderbuffer Decompression Patches

    A set of 27 patches published this week for GBM and the Intel Mesa driver provide for significant bandwidth savings.

    Intel's Ben Widawsky published the set of patches enabling renderbuffer decompression for the i965 driver plus the necessary GBM modifications. With these patches there is the potential for massive bandwidth savings. Results shared by Widawsky on a Skylake GT4 GPU show the compression dropping the read bandwidth from 603 MiB/s to 259 MiB/s and the write bandwidth dropping from 615 MiB/s to 337 MiB/s, when using a modified version of kmscube for testing.

  • Razer is now a member of the consortium responsible for Vulkan-based graphics

    The Khronos Group made a brief announcement on Thursday, stating popular PC gaming peripheral maker Razer is now a Contributor Member. The Khronos Group is the non-profit consortium behind the new open-source Vulkan Application Programming Interface (API) that is becoming more commonly used in PC gaming. It’s an alternative to the long-used DirectX and OpenGL graphics APIs.

  • Hardware maker 'Razer' has joined The Khronos Group to back open standards
  • Razer Joins The Khronos Group

    Razer joining The Khronos Group looks to be a VR/AR play, but will hopefully help further push Vulkan and other Khronos standards to gamers. The brief announcement at Khronos.org reads in part, "...Razer co-founded OSVR, an open-source platform that integrates VR, AR and mixed reality hardware and software APIs that support a universal VR ecosystem."

  • Plans Emerge For Releasing Mesa 13.1

    Mesa release manager Emil Velikov has laid out his draft of a release schedule for the next major Mesa release.

    Emil has proposed that Mesa 13.1 be officially released around 3 February, but for that to happen the feature freeze and RC1 would be on 13 January followed by weekly release candidates until declaring it ready. This proposed Mesa 13.1 release schedule was laid out today on Mesa-dev.

  • Multiseat systems and the NVIDIA binary driver

    Ever since our school switched to Fedora on the desktop, I’ve either used the onboard Intel graphics or AMD Radeon cards, since both are supported out of the box in Fedora. With our multiseat systems, we now need three external video cards on top of the onboard graphics on each system, so we’ve bought a large number of Radeon cards over the last few years.

  • MSM-Next Prepares Adreno A5xx Support For Linux 4.10

    On Tuesday was the MSM-Next submission by Red Hat developer Rob Clark of these Freedreno MSM changes to be sent to mainline for the Linux 4.10 kernel.

    Notable with this MSM-Next pull request is the addition of Qualcomm Adreno A5xx support. Adreno A500 series support coming to this open-source driver stack was covered earlier this week in Qualcomm Adreno A5xx Open-Source Driver Bringup For Freedreno.

  • Amazon Working On EC2 Linux OpenGL Support, Considering Vulkan

    Amazon Web Services today revealed more information about their EC2 Elastic GPUs support they are working to implement in the cloud.

    Amazon's Elastic GPUs will be offered in four different tiers and range in GPU memory capacity from 1GB to 8GB. They also revealed their work on an Amazon-optimized OpenGL library for Elastic GPUs. They shared that initially there is just Windows support for OpenGL but they are working to support Amazon Linux AMI with their OpenGL implementation. They are also looking at Vulkan support (and DirectX too, sadly).

  • This week in vc4 (2016-12-05): SDTV, 3DMMES, HDMI audio, DSI
    The Raspberry Pi Foundation recently started contracting with Free Electrons to give me some support on the display side of the stack. Last week I got to review and release their first big piece of work: Boris Brezillon's code for SDTV support. I had suggested that we use this as the first project because it should have been small and self contained. It ended up that we had some clock bugs Boris had to fix, and a bug in my core VC4 CRTC code, but he got a working patch series together shockingly quickly. He did one respin for a couple more fixes once I had tested it, and it's now out on the list waiting for devicetree maintainer review. If nothing goes wrong, we should have composite out support in 4.11 (we're probably a week late for 4.10).

  • Rugged Skylake embedded PC has wide range power
    Axiomtek’s “eBOX565-500-FL” computer runs Linux or Windows on dual-core Intel 6th Gen CPUs, and offers four USB 3.0 ports and wide-range power. The eBOX565-500-FL updates the two-year-old eBOX560-880-FL embedded PC, which provides dual-core Intel 4th Gen “Haswell” Core and Celeron CPUs. The very similar eBOX565-500-FL instead taps the 14nm Intel 6th Gen “Skylake” ULT processors, once again offering two dual-core options: the 2.4GHz Core i5-6300U and the 2.0GHz Celeron 3955U.

  • How Virtualized Networks Will Save Us From Dropped Calls
    We’ve all been the victim of a dropped mobile phone call and know how frustrating it can be. However, virtualized networks provide network operators with powerful tools to detect and recover from network disruptions, or “faults,” that can drop calls for thousands of subscribers simultaneously. The Open Platform for Network Functions Virtualization (OPNFV) project together with OpenStack have developed features in software that add resiliency to mobile networks and enable them to recover from network and other outages.
  • It’s Brexploitation! Microsoft punishes UK for Brexit with cloud price-gouging
    “My own story would not have been possible but for the democratizing force of Microsoft technology reaching me where I was growing up,” CEO Satya Nadella told shareholders this week. But the price of that “democratizing force” is about to go up, with Britons uniquely singled out. Microsoft has reiterated to Azure customers that prices will go up by 22 per cent from January 1st. The problem? The price rise is far greater than any exchange rate post-Brexit fluctuations might justify. Microsoft’s biggest European data centre is in Dublin, a member of the Euro currency. The Euro hovered around €1.28 to one pound for the first six months of the year, before crashing after Brexit. It’s now €1.19, a depreciation of just 9 cents, or 7 per cent. The value of the British pound has weakened more dramatically against the US dollar, dropping by 18.9 per cent since 24 June - the day after Brits voted to leave the EU. For new Office or Azure cloud customers in the UK, no exchange rate can justify any price rise at all. In September, Microsoft made Azure available in UK data centres.
