A Look At The Clear Linux Performance Over The Course Of 2018

With the end of the year quickly approaching, it's time for our annual look at how the Linux performance has evolved over the past year from graphics drivers to distributions. This year was a particularly volatile year for Linux performance due to Spectre and Meltdown mitigations, some of which have at least partially recovered thanks to continued optimizations landing in subsequent kernel releases. But on the plus side, new releases of Python, PHP, GCC 8, and other new software releases have helped out the performance. For kicking off our year-end benchmark comparisons, first up is a look at how Intel's performance-optimized Clear Linux distribution evolved this year.

AMD Adding STIBP "Always-On Preferred Mode" To Linux

Initially during the Linux 4.20 kernel merge window with the STIBP addition for cross-hyperthread Spectre V2 mitigation it was turned on by default for all processes. But that turned out to have a sizable performance hit so the behavior was changed to only turn it on for processes under SECCOMP or when requested via the PRCTL interface. However, AMD is landing a patch that for select CPUs will have an always-on mode as evidently that's preferred for some AMD processors.

Radeon ROCm 1.9.1 vs. NVIDIA OpenCL Linux Plus RTX 2080 TensorFlow Benchmarks

Following the GeForce RTX 2080 Linux gaming benchmarks last week with now having that non-Ti variant, I carried out some fresh GPU compute benchmarks of the higher-end NVIDIA GeForce and AMD Radeon graphics cards. Here's a look at the OpenCL performance between the competing vendors plus some fresh CUDA benchmarks as well as NVIDIA GPU Cloud TensorFlow Docker benchmarks.

Mesa 19.0 RADV Vulkan Driver Gets New Fixes To Help DXVK Gaming

Samuel Pitoiset of Valve's Linux graphics driver team has landed some fresh patches in Mesa 19.0 (and also marked for back-porting to the stable branch) to help out the DXVK gaming experience for Windows games using Direct3D 11 that are re-mapped to run on top of the Vulkan graphics API.

Linux Is Already In Good Shape For The New Features Of Intel Gen11 Graphics & Icelake

Besides seeing Icelake demos at the Intel Architecture Day that were running on Ubuntu, with closely tracking the Linux kernel's development most of the new features presented for Sunny Cove and Gen11 graphics have already been merged or at least available in patch form for some months within the Linux ecosystem. Here's a look at the features talked about yesterday and their state on Linux.

Intel Working On Open-Sourcing The FSP - Would Be Huge Win For Coreboot & Security

Intel's Architecture Day on Tuesday was delightfully filled with an overwhelming amount of valuable hardware information, but Intel's software efforts were also briefly touched on too. In fact, Raja Koduri reinforced how software is a big part of Intel technology and goes in-hand with their security, interconnect, memory, architecture, and process pillars and that's where their new oneAPI initiative will fit in. But what learning afterwards was most exciting on the software front.

Intel Details Gen11 Graphics & Sunny Cove For Icelake

At Intel's architecture day, the company finally detailed their "Gen 11" graphics that we've been seeing open-source Linux graphics driver patches for many months (Intel OTC posted their initial open-source display driver code in early January and has continued the enablement work since) albeit elusive in substantive user details and hardware until Icelake. But today at least we can share more about the significant improvements with Gen11 graphics.

ODROID-XU4: Much Better Performance Than The Raspberry Pi Plus USB3 & Gigabit Ethernet @ $60

Hardkernel recently sent over the ODROUD-XU4 for benchmarking. This ARM SBC that just measures in at about 82 x 58 x 22 mm offers much better performance than many of the sub-$100 ARM SBCs while also featuring dual USB 3.0 ports, Gigabit Ethernet, eMMC storage, and is software compatible with the older XU3 ARM SBCs. Here's a look at the performance of the ODROID-XU4 compared to a variety of other single board computers.

An Initial Look At The Intel Iris Gallium3D Driver Performance

One of the most exciting developments in the open-source Intel driver space this year was the Iris Gallium3D driver taking shape as what's destined to eventually succeed their "classic" i965 Mesa driver. With Iris Gallium3D maturing, here's a look at how the performance currently stacks up to their mature OpenGL driver.

Arch Linux Users With Intel Graphics Can Begin Enjoying A Flicker-Free Boot

It looks like the recent efforts led by Red Hat / Fedora on providing a flicker-free Linux boot experience and thanks to their upstream-focused approach is starting to pay off for the other desktop Linux distributions... A flicker-free boot experience can now be achieved on Arch Linux with the latest packages, assuming you don't have any quirky hardware.

Adobe Customer Care: There Hasn't Been Enough Demand For Linux

Besides the lack of games, one of the other pressing reasons why some desktop/workstation users haven't migrated full-time to Linux has been over the lack of Adobe's Creative Suite working natively on Linux (and the Wine-based options often only working well for dated versions of Adobe's software). But if you hope to see Adobe Linux software, their customer care recommends you vote.

The Open-Source NVIDIA "Nouveau" Linux Driver Performance At The End Of 2018

As it's been a while since last looking at the NVIDIA vs. Nouveau Linux OpenGL driver performance, here's a look at the current performance difference as the end of the year quickly approaches. This benchmarking roundabout features multiple generations of GeForce GPUs while testing with the NVIDIA 415 proprietary driver against the Nouveau stack on Linux 4.19 and Mesa 19.0-devel.

Initial i.MX8 SoC Support & Development Board Possibly Ready For Linux 4.21

While the i.MX8 series was announced almost two years ago and the open-source developers working on the enablement for these new NXP SoCs hoped for initial support in Linux 4.17, the Linux 4.21 kernel that will be released in the early months of 2019 is slated to possibly have the first i.MX8 support in the form of the i.MX8MQ and also supporting its development/evaluation board.

Unvanquished Open-Source Game Sees Its First Alpha Release In Nearly Three Years

Unvanquished had been easily one of the most promising open-source games several years back with decent in-game visuals/art, a continually improving "Daemon" engine that was a distant mod of ioquake3 while leveraging ETXReaL components and more, and all-around a well-organized, advancing open-source game project. Their monthly alpha releases stopped almost three years ago while today that's changed just ahead of Christmas.
