RADV Driver Lands Support for VK_KHR_shader_fma (www.phoronix.com)

The RADV Vulkan driver has recently integrated support for the VK_KHR_shader_fma extension, which was added to the Vulkan specification last year. This extension enables applications, particularly in machine learning and scientific computing, to perform correctly-rounded fused-multiply add (FMA) operations. The introduction of VK_KHR_shader_fma is significant as it allows for improved floating-point accuracy and efficiency when utilizing GPU acceleration, a crucial aspect for high-precision numerical computations. Previously, Vulkan provided an fma primitive, but its results were not guaranteed to be accurately fused, leading to potential inaccuracies in critical applications. With the new support from the RADV driver, developers can now leverage the FMA operation directly, reducing the need for costly emulations and ensuring reliable accuracy in their algorithms. This advancement not only enhances the performance of applications reliant on Vulkan but also positions it more competitively for tasks demanding high computational precision in AI and ML contexts.
