The RADV Radeon Vulkan driver in Mesa has gained support for the VK_KHR_shader_fma extension, which will ship in Mesa 26.2. This extension enables correctly-rounded fused-multiply add (FMA) operations via SPV_KHR_fma, providing guaranteed floating-point accuracy for machine learning and scientific computing workloads using Vulkan for GPU acceleration. Previously, Vulkan exposed an FMA primitive that wasn't guaranteed to be a true fused operation, forcing applications to emulate it at significant cost.
