Based on the patch description, shouldn't the dependency allow compile-testing only if both XE and I915 are turned off, as in depends on X86 || (DRM_XE=n && DRM_I915=n && COMPILE_TEST) ? As far as I can tell, i915 and xe will attempt (and fail) to use MEI if that is enabled, so there is no point in enabling INTEL_MEI outside of compile-testing even if XE is built. Arnd
