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.

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.
