DragonFlyBSD vs. FreeBSD vs. Ubuntu 20.04 On Intel's Core i9 10900K Comet Lake

Filed under
Graphics/Benchmarks

One of the areas where Intel has the leg up over AMD when it comes to open-source software support is on the BSD side where generally the likes of FreeBSD and DragonFlyBSD often exhibit better out-of-the-box support at launch. Here is a look at how DragonFlyBSD and FreeBSD are running on the Core i9 10900K "Comet Lake" processor with Z490 motherboard.

Tested for this article were the Core i9 10900K at stock speeds with the Gigabyte Z490 AORUS MASTER motherboard. The BSD candidates for this testing were FreeBSD 12.1 and DragonFlyBSD 5.8.1 as the latest stable releases for these two BSDs. Long story short, the support experience for this latest-generation Intel desktop platform was smooth: the only exception was the Ethernet not working out of the box, but that isn't surprising considering even on the Linux side 5.6 or newer is needed. But once plugging in a USB Ethernet adapter, it was off to the races in running DragonFlyBSD and FreeBSD on this i9-10900K box.

  • Zink Is Now OpenGL 3.0 Complete For Generic GL Over Vulkan

    A few days ago I wrote about Zink now exposing GLSL 1.30 shader support as one of the few remaining hurdles for exposing OpenGL 3.0 support for this Gallium3D OpenGL-on-Vulkan implementation. It turns out this same week, Zink would already cross the significant OpenGL 3.0 milestone.

    As of this morning, Zink has now marked its OpenGL 3.0 support as complete with all necessary functionality being exposed.

  • RADV+ACO Lands FP16 Features - One Step Closer To Making ACO The Default

    The Mesa Radeon Vulkan "RADV" driver's ACO shader compiler back-end has merged its FP16 related bits and in turn putting the ACO back-end very close to being enabled by default for this open-source AMD Vulkan driver.

    VK_AMD_gpu_shader_half_float, VK_AMD_gpu_shader_int16, and shaderFloat16 are now working and enabled when using the ACO back-end. The work was merged on Wednesday for Mesa 20.2.

  • AMD Posts New AMDGPU Patches For UVD Video Decode For GCN 1.0

    One of the main blockers from AMD Radeon GCN 1.0 "Southern Islands" GPUs achieving feature parity when using the newer AMDGPU DRM kernel driver rather than the older "Radeon" DRM kernel driver has been in regards to UVD video decoding. But in 2020 it looks like that might finally change.

    For years there have been experimental patches for UVD with GCN 1.0 on the AMDGPU driver albeit never merged and hasn't come up now in several years. But surprisingly today an AMD engineer posted new patches for bringing GCN 1.0 UVD support to AMDGPU.

  • Intel's IWD 1.8 Wireless Daemon Released With WiFi P2P Support

    The iNet wireless daemon (IWD) software developed by Intel's open-source team have released IWD 1.8.

    IWD 1.8 release is the latest version of this Linux wireless daemon developed by Intel as an alternative to WPA_Supplicant and supports integrating with the likes of NetworkManager, systemd's networkd, and Intel's ConnMan software.

  • NVIDIA, Intel Post New Windows 10 Graphics Drivers For WSL2 Linux App Support

    Intel and NVIDIA have both published new Windows 10 graphics drivers that support the new experimental capabilities coming to Windows Subsystem for Linux 2 (WSL2) for running Linux GUI applications atop Windows and ultimately for exposing GPU compute capabilities as well inside the WSL2 environment.

  • Intel Vulkan Driver Adds Pipeline Creation Cache Control Extension

    Intel's open-source "ANV" Vulkan driver has landed support for the recent VK_EXT_pipeline_creation_cache_control extension.

    VK_EXT_pipeline_creation_cache_control was introduced back in March with Vulkan 1.2.135. VK_EXT_pipeline_creation_cache_control exposes information on pipeline creation costs for helping to notify in advance of potentially expensive hazards during Vulkan pipeline creation.

  • GFX1030 Target Merged Into LLVM 11 AMDGPU Back-End For Navi 2

    Following the recent Linux kernel and Mesa patches for AMD "Sienna Cichlid" enablement for this "Navi 2" graphics processor, the AMDGPU LLVM compiler back-end support has been merged into LLVM 11.

    Sienna Cichlid from the earlier RadeonSI patches confirm using "GFX1030" as the target and that support was merged last night into the LLVM 11 compiler development code-base. AMDGPU LLVM serves as the default shader compiler back-end for the RadeonSI Gallium3D driver, currently for RADV albeit transitioning to ACO, the AMDVLK Vulkan driver, and other components like ROCm.

  • Radeon RADV Driver Merge Request Opened To Use ACO By Default

    A merge request opened at the end of last week would now have the Mesa Radeon Vulkan "RADV" driver default to using the Valve-backed ACO shader compiler in place of the default LLVM AMDGPU back-end.

    ACO is the back-end that Valve has been funding for faster shader compile times and more performance optimized at least for games. The AMDGPU LLVM back-end meanwhile is what RADV has used by default up until now and is currently used exclusively by the RadeonSI Gallium3D driver as well as other official AMD driver components.

  • Zink OpenGL-Over-Vulkan Now Exposes GLSL 1.30

    The Zink Mesa driver for implementing OpenGL over the Vulkan API is now quite close to hitting OpenGL 3.0.

    Zink has been striving for OpenGL 3.0 compatibility for some time and is getting close to crossing that prominent threshold. Merged over night was exposing GLSL 1.30. GLSL 1.30 is the shading language version for OpenGL 3.0.

Running Linux 5.8-rc1 Benchmarks On The Intel Core i9 10900K + Radeon RX 5700 XT

Filed under
Graphics/Benchmarks

Since yesterday's big release of Linux 5.8-rc1 I have begun benchmarking this new kernel on various systems. Here are some tests on the first system that was being vetted, the Intel Core i9 10900K Comet Lake with Radeon RX 5700 XT graphics.

See our Linux 5.8 feature overview to learn about all of the changes for this next kernel version. When it comes to overall performance, at least with this i9-10900K system in most benchmarks there wasn't broad performance differences compared to Linux 5.7/5.6 stable series.

mesa 20.0.8

Filed under
Graphics/Benchmarks

Hi list,

I'd like to announce mesa 20.0.8 is now available. This is the last planned
release of the 20.0.x series, and users are advised to consider the 20.1.x
series instead.

There were a couple of blocking issues that held this release up, so it's bit
larger than normal, especially for one so late in the series. Overall though the
changes are fairly normally distributed across the tree, with drivers for Intel
and AMD hardware making up the majority of the changes, and little bits here and
there for everything else.

Dylan

AMD Ryzen 3 3300X vs. Intel Core i3 10100 In 350+ Benchmarks

Filed under
Graphics/Benchmarks

Following our Intel Core i5 10600K and Core i9 10900K Linux benchmarks, here is a look at the lowest-end Core "Comet Lake" processor in the form of the Core i3 10100. Thanks to the increased pressure from AMD Ryzen, Intel now has a 4 core / 8 thread Core i3 processor at less than $150 USD. Here is a head-to-head matchup of the AMD Ryzen 3 3300X and Intel Core i3 10100 processors in more than 350 benchmarks while also looking at the power and thermal efficiency in this largest comparison to date for these low-end desktop CPUs.

The Ryzen 3 3300X launched back in May to great success for budget desktop users. The Ryzen 3 3300X as a reminder is 4 cores / 8 threads, 3.8GHz base clock. 4.3GHz boost clock. 16MB L3 cache, and a 65 Watt TDP while retailing in the $120~130 USD range.

Graphics Stack: Drivers, ROCm and X.Org Modesetting

  • Free user space for non-graphics drivers

    In the kernel graphics world, there has been a longstanding "line in the sand" that disallows merging kernel drivers without a corresponding free-software user-space driver. The idea is that not having a way to test the full functionality means that the kernel developers cannot verify the proper functioning and security of the driver; changes to the kernel driver may lead to unforeseen (and untestable) problems on the user-space side. More recently, though, we have seen other types of devices with complex drivers, but no useful free user-space piece, that have been proposed for inclusion into the kernel; at least one was merged, but the tide has perhaps turned against those types of drivers at this point—or some of them, anyway.

    In mid-May, Jeffrey Hugo posted an RFC patch for the "Qualcomm Cloud AI 100" device, which is a PCIe card with an application-specific integrated circuit (ASIC) that targets "deep learning" workloads. The device is also referred to as a QAIC device; it presents a modem host interface (MHI) control path and a DMA engine for the data path. These are exposed in the driver as a Linux character device with ioctl() commands to access the data path.

  • AMD Publishes Video To Explain The Radeon Open Compute Stack (ROCm)

    AMD has shared with us that they have published a video to explain in basic terms for the audience at large "What is ROCm?", a.k.a. the Radeon Open Compute stack.

    The video is arguably long overdue with ROCm being several years old, but it has been evolving a lot lately with new features and capabilities for better taking on the likes of NVIDIA CUDA and Intel oneAPI. With AMD increasing securing super-computing wins, they have also been ramping up their efforts on this standards-based GPU compute stack.

  • Intel Developer Posts Latest Patch For Variable Refresh Rate Within X.Org Modesetting

    With Intel supporting Adaptive-Sync/VRR with Gen11+ graphics and these days with effectively only supporting xf86-video-modesetting for X.Org-driven Linux desktops rather than their basically dead xf86-video-intel driver, the Intel open-source Linux developers continue working on plumbing variable refresh rate support into this generic modesetting DDX.

    Last month was more work on porting Adaptive-Sync/VRR to xf86-video-modesetting while this week the latest patch was sent out by Intel's Uday Kiran Pichika.

Redo Rescue Backup and Recovery Live System Gets NFS Share Support, SSH Server

For those not in the know, Redo Rescue is a great, free and easy to use live Linux system based on Debian GNU/Linux that can help you whenever your computer is broken by letting you backup and restore an entire system in just a few minutes. For example, if your computer no longer boots after installing the recent BootHole patches for the GRUB2 bootloader, you can use Redo Rescue to repair the boot. Of course, there are a few other tools that can do the same, but Redo Rescue can also do bare metal restores by replacing the MBR and partition table, re-map original data to a different target partition and even verify the integrity of an existing backup image.
