AMD RDNA4 Paired Context Reg Feature Merged For RADV To Potentially Help Performance
After various commits to Mesa 25.1 in recent days in preparing for a new paired context registers feature of AMD RDNA4 (GFX12 graphics), the feature today is wired up for the Radeon Vulkan driver 'RADV' with the upcoming Mesa 25.1 release
So the command processor (CP) is very slow on the new AMD GPUs and the paired context registers should help reduce the main bottleneck. This merge request today landed the support for the RADV Vukan driver to use paired context regs when in an optimal state. Separately, also merged today is a fix for RDNA4 / RX 9070 series to avoid potential GPU hangs or corruption "garbage" issues after suspend and resume on Linux.
