  • Linux 4.18 AMDGPU Tests: Vega Taking A Hit

    Being roughly mid-way through the Linux 4.18 kernel development cycle, I spent some time this weekend running benchmarks of the AMDGPU DRM driver on Linux 4.18 Git compared to Linux 4.17 stable on three different Radeon graphics cards while using the Mesa 18.1.3 based drivers.

  • Radeon ROCm 1.8.2 Compute Stack In Beta, Might Work Under Ubuntu 18.04 LTS

    A new beta of the Radeon Open Compute "ROCm" stack was quietly made available for v1.8.2.

    While ROCm 1.9 will officially support Ubuntu 18.04 LTS, it looks like the ROCm 1.8.2 beta might contain preliminary Ubuntu 18.04 LTS "Bionic Beaver" support. A ROCm 1.8.2 beta user has commented that he was able to get 1.8.2 working on Ubuntu 18.04 with the Linux 4.16 kernel with the AMDKFD kernel driver.

  • Vulkan-Virgl Continues Progressing For Getting Vulkan Within VMs

    One of the most exciting Google Summer of Code 2018 projects is Vulkan-Virgl for supporting this modern graphics/compute API within virtual machines.

    Vulkan-Virgl is based off the existing Virgl initiative that has been providing OpenGL hardware acceleration to guest VMs using VirtIO-GPU and paired with some Mesa code and the Virgl rendering library. The GSoC 2018 project is making Virgl work with both OpenGL and Vulkan APIs.

  • Google's Gasket Driver Framework Landing For Linux 4.19

    Queued into the staging code for introduction with the Linux 4.19 kernel is the Gasket driver framework and the first driver based upon it, Apex.

    Gasket in this context is short for Google ASIC Software, Kernel Extensions, and Tools. The Gasket framework aims to make it easier to develop thin kernel drivers that provide the basic functionality in kernel-space but any extra functionality is to be achieved in user-space code.

  • MoltenVK Gets Patches To Workaround iOS API Issue, App Store Rejection

    A new pull request has been submitted to MoltenVK, the open-source project for mapping the Vulkan graphics/compute API over Apple's Metal to run on iOS/macOS. This pull request is working to address the issue that caused at least one MoltenVK-using iPhone/iPad game to be rejected from the Apple App Store.

  • RADV Vulkan Driver Gets Minor CPU Overhead Reductions, Conditional Rendering Patches

    Samuel Pitoiset of Valve's open-source Linux GPU driver team has been particularly busy in recent days with "RADV" Radeon Vulkan driver enhancements.

    Pitoiset this weekend sent out patches for enabling the new VK_KHR_create_renderpass2 extension, which was introduced in Saturday's release of Vulkan 1.1.80. RenderPass2 allows for render passes to be easily extended.

  • RADV Driver Gets Faster Shader LLVM Compilation

    It's an exciting day in RADV land as in addition to work on the new Vulkan 1.1.80 extensions, David Airlie landed a patch he's been baking for speeding up the shader compilation performance for this open-source Radeon Vulkan driver within Mesa.

Filed under
Graphics/Benchmarks

Chances are if you are spending more than $400 USD to have the Intel Core i7 8086K, the limited edition processor that is Intel's first to have a turbo frequency at 5.0GHz (and can easily overclock on all cores to 5.0+ GHz), you probably care a great deal about your system's performance. For squeezing extra performance out of the hardware, there is a wide variety of software optimizations available. Many of those software optimizations can be found within Intel's own Clear Linux distribution as previously shown while for this i7-8086K benchmarking is a look at how nine Linux distributions compare out-of-the-box when tested on this Coffeelake CPU and all CPU cores overclocked to 5.0GHz.

  • Recent Nouveau Improvements Thanks To A New Contributor

    -
    The open-source NVIDIA "Nouveau" driver continues to be largely a community affair aside from occasional code/documentation dumps (and hardware supplies) from NVIDIA and then Red Hat also employing a few of the key contributors to the Nouveau DRM kernel driver and Nouveau NVC0 Gallium3D within Mesa. When it comes to Red Hat's Nouveau developers like Ben Skeggs and Karol Herbst, they started out as community contributors over the years to this driver. Fortunately, this year has brought another new contributor to the Mesa driver stack.

  • Intel ANV Driver Moves Forward With Vulkan 1.1.80 / KHR_create_renderpass2

    Released yesterday was Vulkan 1.1.80 that offers three new extensions while the Intel ANV open-source driver has begun rolling out patches for supporting this latest Vulkan specification update.

    Lead Intel ANV developer Jason Ekstrand took the opportunity over the weekend to begin sending out the v1.1.80 patches for ANV. The seven patches sent out on Saturday include the routine updating of the Vulkan headers/XML against the 1.1.80 upstream while the other work was focused on the VK_KHR_create_renderpass2 extension. KHR_create_renderpass2 is about making render passes more extensible via sub-structures at render pass creation time.

  • Xilinx ZynqMP DisplayPort DRM/KMS Driver Could Soon Be Ready For Mainline

    Back in January there were Xilinx developers who posted a DRM/KMS driver for their DisplayPort subsystem as part of the ZynqMP SoC. It looks like the driver for this display pipeline may soon be ready for mainline.

    Hyun Kwon of Xilinx posted the latest "XLNX" DRM driver patches on Sunday for their ZynqMP DP KMS code. This driver in its current form is just under six thousand lines of code.

  • Vulkan 1.1.80 Released With Conditional Render, Renderpass2, 8-Bit Storage

    VULKAN --
    After a number of recent Vulkan 1.1 point releases being rather mundane, Vulkan 1.1.80 is out this morning and on top of documentation updates also brings three notable new Vulkan extensions.

    Vulkan 1.1.80 has the usual churn within the documentation to clarify some statements and other work, but exciting us are the three new extensions: VK_EXT_conditional_render, VK_KHR_create_renderpass2, and VK_KHR_8bit_storage.

  • Wayland's Weston Picks Up Force-On, Modifiers, Aspect Ratio Handling

    The past week has seen a number of improvements to Wayland's Weston compositor with new features.

  • Apple Rejects iOS App For Using MoltenVK (Vulkan Over Metal)

    Back in February MoltenVK was open-sourced as part of The Khronos Group and Valve working harder to get Vulkan working on macOS/iOS by mapping it through to using Apple's Metal Graphics/Compute API. The most notable user of MoltenVK on macOS to date is the Vulkan Dota 2 on Mac, but for those looking to use this Vulkan-to-Metal framework on iOS, it looks like Apple might be clamping down.

    We were alerted today by an indie game studio that one of their iOS games is now rejected by Apple over its MoltenVK usage. Specifically, the game was rejected for "non-public API" usage. Apple's rejection letter cites the use of non-public interfaces around IOSurface, which is used directly by MoltenVK.

  • More AMDGPU DRM Updates Sent In For The Linux 4.19 Kernel, Possible Power Savings

    Towards the end of June an initial batch of AMDGPU updates were sent in to DRM-Next for targeting the Linux 4.19 kernel. Now a second round of updates have been submitted of the AMDGPU/Radeon kernel for this next kernel series.

    This latest round of feature updates include making use of DRM core PCI Express (PCI-E) functionality rather than duplicating this PCI-E Gen/Lanes code, scheduler clean-ups, improved code documentation, reworking DC/PowerPlay interfaces in an effort to improve power-savings, initial stutter mode support for the Raven Ridge hardware as another power-savings feature, various PowerPlay updates for Vega 12, and fixes to the "GFXOFF" support that allow for shutting down the graphics engine when not needed.

  • AMDKFD Looking To Be Merged Into AMDGPU Linux DRM Kernel Driver

    While "AMDGPU" is often what is talked about when it comes to the Radeon graphics driver code within the Linux kernel with it being the Direct Rendering Manager (DRM) driver for AMD GCN graphics cards and newer, there is also the AMDKFD kernel driver that plays a vital role for compute support.

    AMDKFD is the AMD Kernel Fusion Driver (dating back to the days of AMD "Fusion") that is basically the AMD HSA compute driver within the kernel. AMDKFD is needed to work with the user-space ROCm/OpenCL compute components and in recent kernel releases is working out well just not for AMD APUs but also the discrete graphics cards. After relying upon out-of-tree kernel code for a while to get good compute support going, with Linux 4.17~4.18, things are looking bright.

  • wayland-protocols 1.15

    wayland-protocols 1.15 is now available.

    This version includes a new unstable protocol that enables clients to allow the compositor to draw window decorations.

  • Wayland-Protocols 1.15 Adds XDG-Decoration Protocol For Server-Side Window Decorations

    Wayland-Protocols 1.15 has been released that introduces the new (unstable) XDG-Decoration protocol for drawing window decorations with Wayland.

    The XDG-Decoration protocol is responsible for negotiating server-side rendering of window decorations for XDG top-level windows. By using this protocol, it provides a standardized way for Wayland compositors to draw window decorations and to send the preference to the clients. Clients can request server-side decorations with this protocol, which is based upon the server-side decoration work done so far by the KDE and Sway groups.

  • Maxwell & Newer Now Support Multi-Sampled Images For Nouveau NVC0

Benchmarking The Performance Impact Of Speculative Store Bypass Disable For Spectre V4 On Intel Core i7

Filed under
Graphics/Benchmarks

In late May Spectre V4 was made public and coinciding with the public reveal was the Linux kernel patches for the Speculative Store Bypass Disable (SSBD) mode for mitigating this latest side-channel attack. For SSBD on Intel CPUs, updated microcode is required and those patched microcode files are now being delivered down through new BIOS updates from motherboard vendors. In recent days with seeing ASUS motherboards get the updated supported, I decided to run some initial Core i7 Coffeelake benchmarks with/without the SSBD support being enabled in the Linux kernel.

Graphics: Intel and AMD Developments

  • Intel Has Quietly Been Working On A New Gallium3D Driver Being Called "Iris"
    After resisting Gallium3D for the past decade with a preference on continuing to maintain their "i965" Mesa classic driver and all they've invested into its compiler stack and more, it seems times are changing as the open-source Intel team has been starting up development of a modern Gallium3D driver. This is not to be confused with the former i915g or i965g efforts from about a decade ago that were the experiments of Tungsten/LunarG for driver research/experimentation purposes or in the case of i915g to handle some features with LLVM in software, but this is a modern Gallium3D driver targeting their current hardware.
