  • Linux 5.2 Ups Laptop Support From A New Intel Power Button Driver To Better Ryzen Input

    Both Intel and AMD laptop hardware are seeing various improvements coming with the in-development Linux 5.2 kernel.

    First up, Linux 5.2 will finally offer better compatibility with many AMD Ryzen laptops out there... In particular, as previously covered, the new AMD PCIe MP2 I2C controller driver has been merged and allows many laptop touchpads / touchscreens to finally function accordingly under Linux. It has taken a long time for this AMD driver to get into shape for mainline but it's here with Linux 5.2 to finally provide out-of-the-box/working touchpad/touchscreen support without requiring an out-of-tree DKMS module or hitting other snags.

  • Working OpenCL Through Gallium3D Clover With LLVM To SPIR-V Conversion

    Karol Herbst of Red Hat who has been working for more than the past year on providing OpenCL support in Gallium3D's "Clover" state tracker via SPIR-V so it can easily work with drivers like Nouveau seems to be approaching the finish line. 

  • Vulkan 1.1.108 Released With Two New Extensions

    It's been almost a month since the last Vulkan spec update with Vulkan 1.1.107, which is a long time considering they go through some periods of almost weekly updates, but out today is v1.1.108 and it introduces two new extensions. 

    Vulkan 1.1.108 does bring with it a number of clarifications and corrections to the documentation itself. The Vulkan 1.1.108 changes appear mostly routine and nothing too notable when it comes to the fixes. 

  • Phoronix Test Suite 8.8 Further Enhances Open-Source, Automated Windows Benchmarking

    While we have endless passion and fun for Linux (and BSD) benchmarking, with Phoronix Test Suite 8.8 being released there are yet more improvements for our open-source, automated and repeatable benchmarking on Microsoft Windows.

Red Hat Enterprise Linux 8.0 Benchmarks Against RHEL 7.6, Ubuntu 18.04.2 LTS, Clear Linux

Filed under

Continuing on from the initial Red Hat Enterprise Linux 8.0 benchmarks last week, now having had more time with this fresh enterprise Linux distribution, here are additional benchmarks on two Intel Xeon servers when benchmarking RHEL 8.0, RHEL 7.6, Ubuntu 18.04.2 LTS, and Clear Linux. RHEL 8.0 is certainly delivering much better out-of-the-box performance than its aging predecessor but how can it compete with Ubuntu LTS and Clear Linux?

As a reminder as to what is shipped by each of these Linux distributions, the core components include:

Red Hat Enterprise Linux 7.6 - RHEL 7.6 uses a (heavily patched) Linux 3.10 kernel, GCC 4.8.5 compiler, and XFS file-system by default.

Red Hat Enterprise Linux 8.0 - RHEL 8.0 runs with the Linux 4.18 kernel, GCC 8.2.1 compiler, and XFS file-system by default. There is a slew of updated packages compared to RHEL7 and what's available there, including other changes like changing over to Retpolines for the Spectre V2 mitigations.

  • AMD EPYC CPUs, AMD Radeon Instinct GPUs and ROCm Open Source Software to Power World’s Fastest Supercomputer at Oak Ridge National Laboratory
  • Open-source Linux drivers for the Intel Gen11 GPU are now feature-complete

    The open-source OpenGL and Vulkan Linux drivers for the upcoming Intel Gen11 GPU are now considered to be complete according to code updates spotted by Phoronix. The drivers will be a part of the Linux 5.2 kernel and are said to be working at full performance.

  • Intel's Gallium3D Driver Will Now Try To Recover From GPU Hangs

    The Intel Gallium3D OpenGL driver performance is now in good shape for this new open-source Intel Linux GL driver compared to its "classic" Mesa driver, but there are still various other features to be ironed out before this "Iris" driver can become the new default. One of the items now crossed off the list is GPU hang recovery.

    As of this past week, new code for Mesa 19.2 introduces support for this Intel Gallium3D driver to recover from GPU hangs. The driver will now attempt to detect when a GEM memory context has been banned and to create a new context and reinitialize the state, hopefully getting past whatever caused the original GPU hang.

Benchmarking The Current Intel OpenCL NEO Driver Compute Performance On Ubuntu 19.04

Filed under

With the recent release of Ubuntu 19.04, the new Intel OpenCL NEO compute stack is available in the archive as "intel-opencl-icd" for easy installation. The former Intel open-source OpenCL "Beignet" driver remains available too, for which we took it for a fun round of benchmarking comparison for seeing how these Intel OpenCL Linux drivers currently compete to just running on the CPU via POCL.

The Intel OpenCL NEO driver stack has matured a lot since it originally took shape in early 2018 and they appear to be further ramping up their OpenCL NEO efforts this year presumably around their SYCL LLVM effort and ultimately the Intel "oneAPI" vision and also important for Xe Graphics discrete hardware. The former Beignet OpenCL driver hasn't been maintained now given OpenCL NEO is the future but does remain available in Ubuntu and other archives for those wanting to run this older driver; for our purposes, Skylake hardware with Iris Pro 580 graphics was used today for being able to compare the former and current/new OpenCL implementations on Ubuntu 19.04.

Mesa 19.0.4

Filed under

Hi list,

Sorry I'm running a bit behind with this release, I was sick on Monday and had
to patch up some autotools problems in the mean time.

It's been a pretty active release, esepcially for how late in the cyle we are.
Radv was the busiest componenet, but there were also a few changes for intel,
radeonsi, some core vulkan work, and a little bit of other stuff here and there.

Hopefully things will start slowing down again.

Just a reminder that there are only two more planned 19.0.x releases, but we may
add more if 19.1 slips.

Performance Testing Intel’s Core i9-9980XE 18-core CPU In Linux

Filed under

We’ve run Intel’s Core i9-9980XE processor through a gauntlet of tests over the past couple of weeks, and we’re going to kick off our look at its performance with some Linux tests. Join us as we tackle Intel’s top Core-series chip across a range of workloads, from compression to encryption and rendering to encoding.
We’ve been hugely focused on Windows benchmarks lately, so it’s about time we spice things up and get another collection of Linux tests together. The last time we tackled CPU performance in Linux was with the launch of Intel’s Core i9-9900K. That article prefaced the Windows one, so it’s a bit of a parallel that we’re kicking off our i9-9980XE coverage the same way (Windows coverage will come soon.)

  • The USB Code For Linux 5.2 Sent In With NVIDIA Contributions & More

    Greg Kroah-Hartman sent in the USB updates on Wednesday for the Linux 5.2 kernel.

    Highlights of the USB changes for this next kernel include:

    - The NVIDIA AltMode driver as the newest open-source contribution from the green giant... This driver is for enabling VirtualLink devices when paired with the newest (currently Turing-based) graphics cards sporting USB-C connectors and intended to be used with next-generation VR headsets. There were also related contributions by NVIDIA developers around allowing firmware flashing support with the "CCG" Cypress code they are using as their controller.

  • Intel OpenCL Linux 19.17.12918 Stack Does Away With Cannonlake Support

    Intel released version 19.17.12918 of their OpenCL "NEO" open-source compute runtime stack this week.

    With this Intel Compute Runtime 19.17.12918 release, they have updated their LLVM-based Intel graphics compiler, disabled Cannonlake "Gen 10" support in the build by default, and now supports SPIR-V 1.2.

  • AMD Radeon Pro Software for Enterprise 19.Q2 for Linux Released

    Shipping today is the "Radeon Pro Software for Enterprise 19.Q2 for Linux" driver package as the newest hybrid driver update for Linux systems with AMD Radeon Pro (and consumer) graphics, aiming to increase performance against NVIDIA Quadro hardware.

    In AMD's press communications today, they are talking up higher performance in real-world design workflows, better support for critical design and productivity workflows, and better workstation power. However, it's not immediately clear how well some of these updates translate on the Linux side with some of the mentioned workstation software is Windows-only. Unfortunately we don't have any Radeon Pro hardware for verification of the Linux driver update performance changes, but at least there is this quarterly Linux driver update out today.

  • Libinput 1.13.2 Released With Better Finger Detection For Apple Touchpads

    While "just a point release", libinput 1.13.2 was released today as the newest update to this widely-used X11/Wayland Linux input handling library. With libinput 1.13.2 are two notable fixes.

    First up, those using Apple Bluetooth-enabled touchpads will find better finger detection with this update. The Apple Bluetooth touchpads now detect the correct touch size and as such is able to provide more reliable finger detection.

The New Intel Gallium3D OpenGL Driver Performance Is In Great Shape For Mesa 19.1

Filed under

With Mesa 19.1 now under its feature freeze, here is a look at how the new Intel "Iris" Gallium3D OpenGL driver is performing for its debut in this next quarterly Mesa feature release. Benchmarks from a Skylake NUC with Intel Iris Pro 580 graphics just wrapped up for looking at the performance of the Intel Gallium3D driver against its existing open-source "i965" Mesa OpenGL driver.

The Intel Gallium3D driver is one of the new additions coming with Mesa 19.1. Mesa 19.1.0 should debut around the end of May or June and will feature this Gallium3D driver as an experimental option in place of the default i965 driver, but for Broadwell graphics and newer can be activated via the MESA_LOADER_DRIVER_OVERRIDE=iris environment variable. Intel developers are hoping by the end of 2019 that this Gallium3D driver will be mature enough to enable by default for Broadwell and newer; Haswell and older hardware will continue to be supported by the i965 driver as those older generations of graphics will not be supported by Iris.
