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with difficult to debug issues where a modern Linux host with SEV-SNP may try booting a Linux virtual machine with an outdated kernel.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.
