RADV Enables VK_EXT_host_image_copy By Default for RDNA1 GPUs

Summary: The open-source Radeon RADV Vulkan driver previously offered experimental host image copy support via the VK_EXT_host_image_copy extension. This support has now been enabled by default for RDNA1 GPUs.

This news concerns RADV, the open-source Radeon Vulkan driver, enabling the VK_EXT_host_image_copy extension by default for RDNA1 architecture GPUs. This extension aims to optimize image copy operations on the host side. Previously offered experimentally, this feature is now becoming standard for a broader user base.

The VK_EXT_host_image_copy extension provides a mechanism for copying image data residing in host memory that the GPU cannot directly access. This can offer performance improvements, especially when the CPU needs to transfer data to or read data from GPU memory. Such operations are typically encountered in scenarios like texture loading or render target reads.

From the perspective of live systems and infrastructure, this change could mean a performance boost for Vulkan-based applications and games. Reduced latency in image copy operations can positively impact overall system responsiveness and frame rates. Applications running on RDNA1-based systems, in particular, will benefit from this optimization.

It is important for engineers to consider this development, especially when developing Vulkan applications or analyzing the performance of existing systems. The default inclusion of this feature with new driver updates can simplify development processes by eliminating the need for manual configuration.
