Exploring Mesa 25.0: Enhanced Linux Graphics Stack with Vulkan 1.4 Support for RADV, ANV, and NVK

The Mesa 25.0 open-source graphics stack has been released, presenting a significant update that enhances various included graphics drivers.

One of the main highlights of Mesa 25.0 is the introduction of Vulkan 1.4 support for RADV (AMD), ANV (Intel), NVK (NVIDIA), Turnip (Qualcomm), Asahi (Apple), and Lavapipe (software) drivers. Additionally, it adds Vulkan 1.1 support along with new features such as shaderInt16, shaderInt64, imageCubeArray, depthClamp, and more for the PanVK driver, which is specifically for Mali GPUs.

The PanVK graphics driver also now supports an array of new Vulkan extensions, including:

  • VK_KHR_dedicated_allocation
  • VK_KHR_global_priority
  • VK_KHR_index_type_uint8
  • VK_KHR_map_memory2
  • VK_KHR_multiview
  • VK_KHR_shader_non_semantic_info
  • VK_KHR_vertex_attribute_divisor
  • VK_KHR_zero_initialize_workgroup_memory
  • VK_KHR_shader_draw_parameters

Moreover, Mesa 25.0 has incorporated additional support for numerous Vulkan extensions such as VK_KHR_shader_float16_int8, VK_KHR_8bit_storage, and several others.

The update also brings enhancements to numerous games, including notable titles like Black Myth: Wukong, Hogwarts Legacy, Cyberpunk 2077, and Resident Evil series games, enhancing the overall gaming experience within the Mesa graphics stack.

Furthermore, the RADV Radeon Vulkan graphics driver has gained support for new Vulkan extensions such as VK_KHR_depth_clamp_zero_one and VK_KHR_maintenance8. Users can find detailed changes in the release notes on the official Mesa website, where they can also download the source tarball.
