From e5cdb22b2799f2729930ef6394378570c66da251 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Mon, 15 Aug 2016 10:48:56 +0100 Subject: drm/i915: Move assertion for iomap access to i915_vma_pin_iomap Access through the GTT requires the device to be awake. Ideally i915_vma_pin_iomap() is short-lived and the pinning demarcates the access through the iomap. This is not entirely true, we have a mixture of long lived pins that exceed the wakelock (such as legacy ringbuffers) and short lived pin that do live within the wakelock (such as execlist ringbuffers).
