Mesa 24.1 Enables Intel Xe Kernel Driver Support By Default
While the new Intel Xe kernel graphics driver was upstreamed in Linux 6.8 as this modern DRM driver that is opt-in for current generation hardware and aims to be the default for Lunar Lake / Xe2, currently with Mesa you must build the Intel ANV Vulkan and Iris Gallium3D driver code with the "intel-xe-kmd" option to enable compatibility for this alternative kernel driver to i915. With Mesa 24.1 coming next quarter, that Intel Xe kernel driver support will be enabled out-of-the-box...
