From: Chris Wilson Date: Tue, 20 Jun 2017 12:43:19 +0000 (+0100) Subject: drm/i915: Retire the VMA's fence tracker before unbinding X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=760a898d8069111704e1bd43f00ebf369ae46e57;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Retire the VMA's fence tracker before unbinding Since we may track unfenced access (GPU access to the vma that explicitly requires no fence), vma->last_fence may be set without any attached fence (vma->fence) and so will not be flushed when we call i915_vma_put_fence(). Since we stopped doing a full retire of the activity trackers for unbind, we need to explicitly retire each tracker.
