From 8da3fd52711b9e75abb2b2cdd51e152273998265 Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst Date: Tue, 10 Dec 2024 09:31:11 +0100 Subject: [PATCH] drm/xe: Do not attempt to bootstrap VF in execlists mode [ Upstream commit f3b59457808f61d88178b0afa67cbd017d7ce79e ] It was mentioned in a review that there is a possibility of choosing to load the module with VF in execlists mode. Of course this doesn't work, just bomb out as hard as possible.
