With recent NVIDIA's proprietary driver updates continuing to refine their Wayland support, the open-source AMDGPU Linux graphics drivers continuing to be enhanced, and work on the GNOME desktop with Mutter compositor continuing to advance, today's benchmarking article is looking at how the GNOME session under X.Org and Wayland for (X)Wayland is performing across various Linux games. It's been a while since I last ran a X.Org vs. (X)Wayland Linux gaming comparison so today's article is a fresh look from Ubuntu 22.10 while moving to the very latest graphics drivers and newest Steam Play Experimental state.

Code merged last week to Mesa 23.1 by AMD ensures that a linear copy buffer is made on the display/scanout GPU when dealing with EGL contexts under Wayland or X11. This follows an optimization made last year to Mesa's GLX code within X.Org environments for enhancing the PRIME/multi-GPU support...

Merged on Sunday prior to tagging Linux 6.2-rc6 is a late "fix" for the AMD Secure Encrypted Virtualization Secure Nested Paging (SEV-SNP) code to avoid possible situations of undefined behavior with difficult to debug issues where a modern Linux host with SEV-SNP may try booting a Linux virtual machine with an outdated kernel...

The Mesa Radeon Vulkan "RADV" driver's implementation of the graphics pipeline library (VK_EXT_graphics_pipeline_library) is becoming much faster thanks to fast-linking and various pending fixes. In turn this will get games making use of the extension the ability to ideally have no shader pre-caching while still enjoying no in-game stuttering. Valve's Linux graphics driver developers working on RADV have been working through some issues with the RADV graphics pipeline library and for Mesa 23.1 looks like it could be in good shape...

Most of the Mesa Radeon Vulkan "RADV" driver development has been done by the likes of Valve, Google, and Red Hat engineers with it being an "unofficial" driver while AMD supports AMDVLK as their official open-source Vulkan driver as well as supporting their closed-source AMDGPU-PRO Vulkan driver too that shares common code with their Windows Vulkan driver. It was pleasant to see AMD this week though submitting new feature code to RADV...

Last summer Intel published guidance around the Data Operand Independent Timing (DOIT) instruction mode that can be enabled with recent generations of Intel processors to ensure constant time execution for a subset of the Intel instruction set, which can be particularly important for cryptographic algorithms. Linux kernel developer discussions fizzled out last year over handling this DOIT functionality for what is described as a CPU vulnerability with recent Intel CPUs. However, now a Linux kernel patch from a Google developer would enable this change unconditionally for newer Intel CPUs but raises performance concerns.
