Early Benchmarks Of The Linux 4.9 DRM-Next Radeon/AMDGPU Drivers

Filed under
Graphics/Benchmarks

While Linux 4.9 will not officially open for development until next week, the DRM-Next code is ready to roll with all major feature work having been committed by the different open-source Direct Rendering Manager drivers. In this article is some preliminary testing of this DRM-Next code as of 29 September when testing various AMD GPUs with the Radeon and AMDGPU DRM drivers.

Linux 4.9 does bring compile-time-offered experimental support for the AMD Southern Islands GCN 1.0 hardware on AMDGPU, but that isn't the focus of this article. A follow-up comparison is being done with GCN 1.0/1.1 experimental support enabled to see the Radeon vs. AMDGPU performance difference on that hardware. For today's testing was a Radeon R7 370 to look at the Radeon DRM performance and for AMDGPU testing was the Radeon R9 285, R9 Fury, and RX 480. Benchmarks were done from the Linux 4.8 Git and Linux DRM-Next kernels as of 29 September.

  • Libinput X.Org Driver Updated For X.Org Server 1.19

    Peter Hutterer has announced the release of a new version of xf86-input-libinput, the X.Org DDX driver that makes use of libinput for input handling on the X.Org Server.

  • xf86-input-libinput 0.20.0

    Most important fix is the use of input_lock() instead of the old SIGIO stuff to handle the input thread in server 1.19.

  • Mesa 13.0 Planning For Release At End Of October, Might Include RADV Vulkan

    Following the mailing list talk over the past two days about doing the next Mesa release, plans are being discussed for releasing at the end of October and it might have just got a whole lot more exciting.

    Emil Velikov, Collabora developer and Mesa release manager for the past several release series, has commented on that previously discussed mailing list thread. He mentioned he was secretly waiting in hopes of seeing the RADV Radeon Vulkan driver merged for this next release! He said he'd even be willing to see it merged even if it's "not perfect/feature complete."

Ubuntu 16.10 Doesn't Change Much With Performance, Clear Linux Still Leads In Most Tests

Graphics/Benchmarks
Ubuntu

Given yesterday's Ubuntu 16.10 final beta release ahead of the official "Yakkety Yak" debut in two weeks, I decided to run some benchmarks of Ubuntu 16.10 compared to Ubuntu 16.04.1 LTS on the same system plus also throwing in the Intel Clear Linux distribution given it tends to be one of the most performant.

For those that haven't yet tried out Ubuntu 16.10 nor followed its development, GCC 6.2 is now the default compiler in place of GCC 5.4 from Ubuntu 16.04 LTS. Mesa 12.0.3 provides the stock graphics drivers and Linux 4.8 is the stock kernel.

Intel Core i7 6800K Benchmarks On Ubuntu + Linux 4.8

Filed under
Graphics/Benchmarks

While the Core i7 6800K has been available for a few months now, there hadn't been any review on it since Intel hadn't sent out any Broadwell-E samples for Linux testing this time around. However, I did end up finally buying a Core i7 6800K now that the Turbo Boost Max 3.0 support is finally coming together (at first, Intel PR said it wouldn't even be supported on Linux) so that I can run some benchmarks there plus some other interesting items on the horizon for benchmarking. Here are some benchmarks of the i7-6800K from Ubuntu 16.04 LTS with the Linux 4.8 kernel.

  • Linux Unable To Boot Lenovo Yoga 900 & 900; Is Microsoft At Fault?
    The popular device developer Lenovo has verified the claims that Lenovo Yoga 900 and 900s unable to boot Linux OS but only Microsoft Windows 10. The new Lenovo convertible laptop, Lenovo Yoga 900 and 900s, would reject and decline any attempt to install Linux operating system, making users turn their heads to Microsoft as the suspect for this issue. [...] This issue about the OS started when an identity of BaronHK posted on Reddit about installing Linux on the latest Lenovo Yoga book in which BaronHK encountered being blocked by a locked solid state drive (SSD) which Linux cannot define itself, and come up to link the issue to Microsoft.
  • How Ubuntu 16.10 Beta 2 Performance Compares To Some Other Linux Distros
    The final Ubuntu 16.10 Beta for "Yakkety Yak" was released this week and we found its performance doesn't differ much from Ubuntu 16.04 LTS (with the exception of the newer graphics stack) while here are some results comparing it to other modern Linux distributions. Tested for this quick, one-page-article comparison were Ubuntu 16.04.1 LTS, Ubuntu 16.10 Beta 2, Clear Linux 10660, Fedora 24, openSUSE Tumbleweed 20160927, and the Arch-based Antergos 16.9-Rolling release.

  • New Qt 3D Functionality Is Being Worked On
    Sean Harmer of KDAB is organizing work around some upcoming "major Qt 3D features" for the open-source toolkit. It's not known if the next round of Qt 3D features will be ready for the Qt 5.9 tool-kit release, but KDAB is looking to have these new branches for feature work with continuous integration coverage.
  • Cross-compiling WebKit2GTK+ for ARM
    Of course, I know for a fact that many people use local recipes to cross-compile WebKit2GTK+ for ARM (or simply build in the target machine, which usually takes a looong time), but those are usually ad-hoc things and hard to reproduce environments locally (or at least hard for me) and, even worse, often bound to downstream projects, so I thought it would be nice to try to have something tested with upstream WebKit2GTK+ and publish it on trac.webkit.org,

  • Linux Kernel 4.4.23 LTS Has ARM and MIPS Improvements, Updated Filesystems, More
    Immediately after announcing the release of Linux kernel 4.7.6, Greg Kroah-Hartman proudly informed the community about the general availability of the Linux 4.4.23 LTS kernel. The Linux 4.4 kernel is a long-term supported branch, the latest and most advanced one, used in many stable and reliable GNU/Linux operating systems, including Ubuntu 16.04 LTS (Xenial Xerus) and Alpine Linux 3.4. Therefore, it is imperative for it to receive regular updates that bring fixes to the most important issues, as well as other general improvements.
  • From NFS to LizardFS
    If you’ve been following me for a while, you’ll know that we started our data servers out using NFS on ext4 mirrored over DRBD, hit some load problems, switched to btrfs, hit load problems again, tried a hacky workaround, ran into problems, dropped DRBD for glusterfs, had a major disaster, switched back to NFS on ext4 mirrored over DRBD, hit more load problems, and finally dropped DRBD for ZFS.

  • BUS1, The Successor To KDBUS, Formally Unveiled -- Aiming For Mainline Linux Kernel
    BUS1 has been in development as an in-kernel IPC mechanism building off the failed KDBUS project. An "RFC" will soon be sent out to Linux kernel developers about BUS1 and the subject will be discussed at next month's Kernel Summit. David Herrmann, one of the BUS1 developers, presented at this week's systemd.conf conference about the new capability-based IPC for Linux. He talked about how BUS1 is superior to KDBUS, how BUS1 is similar to Android's Binder, Chrome's Mojo, Solaris' Doors, and other common IPC implementations.
  • A New Wireless Daemon Is In Development To Potentially Replace wpa_supplicant
    In addition to the BUS1 presentation, also exciting from the systemd.conf 2016 conference is a thorough walkthrough of a new wireless daemon for Linux being developed by Intel's Open-Source Technology Center. Intel has been developing a new wireless daemon for Linux to potentially replace wpa_supplicant. This new daemon isn't yet public but the code repositories for it will be opened up in the next few weeks. This new daemon has improvements around persistency, WiFi management, reduced abstractions for different operating systems and legacy interfaces, and changes to operation. This daemon is designed to be very lightweight and work well for embedded Linux use-cases especially, including IoT applications.
