AMD Sends Last Minute Fixes To Linux 6.0 For RDNA3 Graphics Cards
AMD Sends Last Minute Fixes To Linux 6.0 For RDNA3 Graphics Cards

Linux 6.0 should be released as stable on Sunday unless Linus Torvalds has last minute reservations and decides to extend the cycle by an extra week. AMD has sent in a last minute set of patches for their AMDGPU kernel driver with Linux 6.0 for dealing with what appear to be the upcoming RDNA3 graphics cards.

Radeon R600 Gallium3D Switches To Modern NIR Backend By Default
Radeon R600 Gallium3D Switches To Modern NIR Backend By Default

After the persistent work by developer Gert Wollny with a desire to improve the aging "R600g" driver that provides open-source OpenGL support for Radeon HD 2000 through HD 6000 series graphics cards, this Gallium3D driver in Mesa 22.3 will now use the NIR back-end by default.

Mesa Radeon Driver "RADV" Ray-Tracing Performance Becoming Viable For Linux Gaming
Mesa Radeon Driver "RADV" Ray-Tracing Performance Becoming Viable For Linux Gaming

In addition to a ~10% performance boost seen yesterday for RADV ray-tracing performance with Quake II RTX, another merge request also made it to Mesa 22.3 for much more significantly bolstering the RADV ray-tracing performance. With all of the recent RADV ray-tracing work, we are finally reaching a point where it's becoming viable for Linux gamers on this open-source driver.

RADV Driver Sees Dramatic Improvement To Reduce CPU Overhead For Draw Calls
RADV Driver Sees Dramatic Improvement To Reduce CPU Overhead For Draw Calls

Mike Blumenkrantz has been working under contract for Valve on the open-source Zink OpenGL-on-Vulkan implementation for Mesa but that work has carried over into the Mesa Vulkan drivers too where there is common overlap. His recent work has been focused on lowering the CPU overhead of some operations with the RADV Vulkan driver.

AMD Releases FidelityFX Super Resolution FSR 2.1

AMD's GPUOpen group has released an updated version of FidelityFX Super Resolution 2. The new FSR 2.1 brings quality enhancements and a reduction in artifacts as the primary benefits over the original FSR2 that was unvelied earlier this year and open-sourced during the summer.

RADV Prepares To Switch Completely To Dynamic Rendering

One of the great things about Jason Ekstrand having joined Collabora at the start of the year is that the former Intel graphics engineer, who was on the team that created their original Vulkan driver, can now work on whatever open-source driver code he wishes. Among other upstream Mesa work, he's recently been contributing to the new "NVK" NVIDIA Vulkan driver and also the RADV driver too.

AMDVLK 2022.Q3.3 Brings Some Performance Tuning For Linux Gamers

AMD has published their latest routine snapshot of AMDVLK, their official open-source Radeon Vulkan driver for Linux systems that is derived from their internal cross-platform Vulkan driver sources and is an alternative to the unofficial but popular Mesa Radeon Vulkan "RADV" driver.

AMD Radeon 680M Graphics Benchmarks Across Various Linux Kernel, Mesa Versions

With the Ryzen 6000 "Rembrandt" mobile processors most exciting about these Zen 3+ SoCs has been the energy efficiency improvements and moving from Vega to RDNA2 graphics as with the Radeon 680M found on the Ryzen 7 PRO 6850U that I have been running many Linux benchmarks on over the past several weeks. For those wondering if it pays off moving to a newer Linux kernel or Mesa version with Radeon 680M integrated graphics, here are some reference benchmarks I recently conducted.

Radeon Pro Software For Enterprise 22.Q2 For Linux Released

Released in June was the Radeon PRO Software for Enterprise 21.Q2 to deliver AMD's enterprise-vetted graphics driver stack to Windows users. Meanwhile recently debuting is the long-awaited adjacent Radeon Pro Software for Enterprise for Linux driver update.

RADV Vulkan Driver Now Supports NVIDIA's Device Generated Commands
RADV Vulkan Driver Now Supports NVIDIA's Device Generated Commands

As of this week in Mesa 22.2, the open-source Radeon Vulkan driver "RADV" has added support for the VK_NV_device_generated_commands extension. This NVIDIA-created extension that has been around for a few years with their hardware allows for the GPU to generate some of the most frequent rendering commands on the hardware itself.

Radeon Software for Linux 22.20 Released With Ubuntu 22.04 LTS Support

While AMD is normally fairly good at promptly supporting major new enterprise Linux distribution releases from Red Hat, SUSE, and Canonical (Ubuntu), this time around with Ubuntu 22.04 LTS it's taken just shy of three months since the official release for them to formally release a new packaged driver supporting it.

AMD Is Hiring To Improve Its Linux Graphics Driver Installation Experience
AMD Is Hiring To Improve Its Linux Graphics Driver Installation Experience

While AMD's open-source Linux graphics driver stack is wonderful if living on the bleeding-edge with a modern Linux distribution, for those on enterprise Linux distributions that tend to stick to older versions of packages for the support lifetime or where wanting to run a vetted/qualified driver stack, it can be more of a pain. For AMD's packaged Linux driver stack it only supports those select enterprise Linux distributions and can run into pain points trying to run elsewhere or even say running brand new LTS distributions at times can lack support. There are also challenges in installing/running the ROCm compute stack outside of the few officially supported Linux distributions by AMD. Fortunately, they are now hiring Linux build engineer(s) to work on such issues.

RADV Remains Competitive To AMD's Radeon Vulkan Windows Driver, Linux OpenGL Dominates
RADV Remains Competitive To AMD's Radeon Vulkan Windows Driver, Linux OpenGL Dominates

I'm currently working on a fresh comparison of the Windows vs. Linux performance for Intel's Alder Lake hybrid processors due to a number of readers inquiring how the OS support has evolved. In the process of carrying out those tests I also ran some fresh Windows vs. Linux tests with the AMD Radeon RX 6800 XT for how the OpenGL and Vulkan driver performance stands.

New Activity Around Adapting ACO Compiler Back-End For RadeonSI
New Activity Around Adapting ACO Compiler Back-End For RadeonSI

As part of the work on the Mesa Radeon Vulkan "RADV" driver, Valve engineers developed the "ACO" compiler back-end that is now used by default for RADV and has shown to deliver better performance at least for RADV than using AMD's official AMDGPU LLVM shader compiler back-end. There has long been talk about adding ACO support to RadeonSI while in recent weeks there has been new code activity on that front.
