From dc6cd912c7cd83ec9859429c552b2986c0386b90 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Thu, 28 May 2020 16:04:52 +0100 Subject: [PATCH] drm/i915/gt: Restore both GGTT bindings on resume We should be able to skip restoring LOCAL (user) binds within the GGTT on resume and let them be restored upon demand. However, our consistency checks demand that the bind flags match the node state, and we cannot simply clear the flags, we need to evict as well. For now, make sure we restore the bind flags exactly upon resume.
