commit 69208c9e1e938cd115fdafdc502b5a7aa99d8d0b Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Tue Oct 10 11:18:16 2017 +0200 drm/i915: Increase atomic update vblank evasion time with lockdep All our mmio writes take forever with lockdep due to the constant lock acquire&dropping we do. Ville has some patches to only acquire the mmio spinlocks once instead for every single mmio, but those aren't ready yet. As an interim solution just extend our budget slightly when lockdep is enabled, to avoid the rare and sporadic noise in CI. v2: I forgot to add the FIXME comment ...
