Intel Workaround For Graphics Driver Regression: "The Platform Problem Going Crazy"

Sent out over the weekend was a patch series for the Intel Linux kernel graphics driver entitled "Time, where did it go?" This set of 42 patches aims to provide incremental improvements to the driver to offset a performance regression in Linux 5.7 that Intel hasn't been able to track down. This this increased complication of the driver to offset the regression is now under the microscope.

RADV ACO Back-End Begins Tackling Navi 2 / GFX10.3 Support

With the "Sienna Cichlid" and "Navy Flounder" open-source driver support as what appear to be the first "Navi 2" GPUs and the first of the "GFX10.3" generation on the graphics engine side there is the initial kernel support with Linux 5.9 and the initial Mesa support for 20.2. That Mesa support has been focused on RadeonSI as the official OpenGL driver as well as Mesa's RADV driver as the Radeon Vulkan driver in-tree but not officially supported by AMD. That RADV support is currently un-tested. Both drivers currently depend upon the "AMDGPU" back-end found in the forthcoming LLVM 11.0 with its initial GFX10.3 support. But now on the RADV driver side there is preliminary GFX10.3 bits landing for the popular "ACO" back-end.

Defaulting Radeon GCN 1.0/1.1 GPUs To Better Linux Driver Is Held Up By Analog Outputs

Switching from the "Radeon" to "AMDGPU" kernel driver on Linux is possible for Radeon GCN 1.0/1.1 era graphics cards and doing so can mean slight performance benefits, the ability to run the AMDVLK or RADV Vulkan drivers, and simply making use of this better maintained driver. But having these original GCN graphics cards default to the modern AMDGPU driver appears held up by the lack of analog video output support with that driver.

After 5 Years, FSGSBASE Support Finally Ready For Linux To Enhance AMD/Intel Performance

The Linux kernel work for making use of the x86_64 FSGSBASE instruction since Intel Ivy Bridge and since then AMD CPUs also is set to finally land with the in-development Linux 5.9 kernel. The FSGSBASE support has the possibility of helping Intel/AMD CPU performance especially in areas like context switching that had been hurt badly by Spectre/Meltdown and other CPU vulnerability mitigations largely on the Intel side.

Intel's Open-Source H.265/HEVC Encoder Sees First Release Of 2020

Intel's Scalable Video Technology team is known for their open-source video encoder work particularly on AV1 and VP9 formats, but they also continue to maintain a high performance H.265/HEVC encoder as well. Intel SVT-HEVC 1.5 was released on Monday as their first major update of the year.

GNU Linux-libre 5.8 Required A Lot Of Deblobbing

Linux 5.8 is one of the biggest releases in a while but that newly-stable kernel also means a lot of the new drivers need to be stripped out or otherwise modified over being reliant on binary-only firmware/microcode or contingent upon other dependencies deemed not free to the Free Software Foundation standards.

Valve's Steam July 2020 Numbers Point To A Small Dip For Linux

While some platforms like Netmarketshare have reported increases month-over-month for Linux desktop usage, that doesn't appear to be translating similarly to the Linux gaming market-share, or at least not at the rate Steam is growing on Windows and macOS. Valve has just published their July 2020 numbers that are part of the Steam Survey.

The Beautiful + Linux-Friendly Unigine 2.12 Engine Released

The Unigine Engine appears to be having great success in the engineering and simulation space more so than for the competitive game engine space, but in any case Unigine 2.12 is now out with this visually stunning engine delivering even more life-like visuals while continuing to be Linux-friendly.
