Wine-Staging Has Been Revived, Working Towards New Release

Wine-Staging has been a flavor of Wine popular with Linux gamers for often carrying bleeding-edge patches and other experimental work prior to being mainlined. But over two months ago, Wine-Staging went silent without any further updates. A few days ago the original maintainers announced they parted ways with the work due to lack of time and would not be issuing any new releases. Now there are new developers taking over.

OpenBSD Gets Mitigated For Meltdown CPU Vulnerability

A few days back FreeBSD 11 stable was mitigated for Meltdown (and Spectre vulnerabilities), which came more than one month after these nasty CPU vulnerabilities were disclosed while DragonFlyBSD was quickly mitigated and the first of the BSDs to do so. While OpenBSD is known for its security features and focus, only today did it land its initial Meltdown mitigation.

Intel Coffee Lake OpenGL Performance On Windows 10 vs. Linux

For those curious about the state of Intel's open-source Mesa OpenGL driver relative to the company's closed-source Windows OpenGL driver, here are some fresh benchmark results when making use of an Intel Core i7 8700K "Coffee Lake" processor with UHD Graphics 630 and testing from Windows 10 Pro x64 against Ubuntu 16.04.3 LTS, Ubuntu with the Linux 4.16 Git kernel and Mesa 18.1-dev, and then Intel's own Clear Linux distribution.

DDR4 Memory Scaling Performance On AMD Raven Ridge / Ryzen 5 2400G

While we all know that APUs crave as fast as system memory as possible, with DDR4 memory kits these days easily costing more than the Ryzen 3 2200G and even the Ryzen 5 2400G, here are some reference results when testing the Ryzen 5 2400G under Linux with memory speeds from DDR4-2133MHz to DDR4-3600MHz.

Intel GLSL On-Disk Shader Cache Enabled By Default

For Mesa 18.0 is the initial Intel shader cache support for archiving compiled GLSL shaders on-disk to speed up the load times of subsequent game loads and other benefits. For the Mesa 18.0 release the functionality isn't enabled by default but it will be for Mesa 18.1.

Xorgproto 2018.3 Brings RandR Leasing + Non-Desktop Monitors

Xorgproto debuted earlier this month as a centralized package of all X.Org protocol headers that used to be versioned and developed independently. Given the slower development now of the xorg-server and lots of the protocols being intertwined, they are now all bundled together. Tuesday marked the 2018.3 release with the new additions for Keith Packard's SteamVR Linux infrastructure work.

A Linux Kernel Driver Is Being Worked On For Valve's Steam Controller

Right now to make most use of the Steam Controller on Linux you need to be using the Steam client while there have been independent user-space programs like SC-Controller to enable Steam Controller functionality without the Steam client running. A new and independent effort is a Linux kernel driver for the Steam Controller.

Even With AMDGPU DC, HDMI/DP Audio Isn't Working Out For All Radeon Linux Users

While the newly-released Raven Ridge APUs could make for nice HTPC systems given the number of compatible mini-ITX/micro-ATX motherboards and these 65 Watt APUs offering Zen CPU cores with Vega graphics, besides the current problematic Raven Ridge graphics support, there are still some broader AMDGPU DC audio problems for newer graphics cards.

Benchmarking Amazon EC2 Instances vs. Various Intel/AMD CPUs

Given the recent performance changes following the Spectre/Meltdown CPU vulnerability mitigation and having just wrapped up some fresh CPU bare metal benchmarks as part of that testing as well as the recent AMD Raven Ridge launch, I've carried out a fresh round this week of benchmarks on various Amazon EC2 on-demand instance types compared to a number of bare metal Intel and AMD processors in looking at how the compute performance compares.

RadeonSI Now Offers NIR Shader Cache Support

Earlier this month Valve Linux GPU driver developer Timothy Arceri landed NIR shader caching support within the Gallium3D Mesa state tracker as an alternative to the existing TGSI IR caching support. Arceri has now worked through implementing this NIR cache support for the RadeonSI driver.

Ryzen 3 2200G Video Memory Size Testing On Linux

One of the discussion items in the forums this week was about the video memory allowance for the Vega graphics on Raven Ridge APUs as well as efficiences or inefficiencies around the TTM memory manager as used by the AMDGPU kernel driver. Here are some vRAM size tests with the Ryzen 3 2200G.

AMD's Raven Ridge Botchy Linux Support Appears Worse With Some Motherboards/BIOS

With my launch testing of the Raven Ridge desktop APUs with the Ryzen 5 2400G and Ryzen 3 2200G there were some stability issues to report and some hangs within games and mode-setting issues. It appears those issues are exacerbated with some motherboards: the past few days with two different AMD B350 motherboards have been a real pain getting the current AMDGPU driver stack working -- and even Linux 4.17 AMDGPU WIP code -- on either of these Raven Ridge APUs.

Marek Working Towards Even Lower SGPR Register Usage

Yesterday well known open-source AMD developer Marek Olšák landed his RadeonSI 32-bit pointers support for freeing up some scalar general purpose registers (SGPRs) and he's continued with a new patch series to alleviate register usage even more.

Wine-Staging Will No Longer Be Putting Out New Releases

Wine-Staging as many of you have known it for the past four years is unfortunately no more. We'll see if other reliable folks step up to maintain this experimental version of Wine but the original developers have sadly stepped away.
