From 10e9bd9ab0322a3929db0bf84ff1ca3f28ed0ee4 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Wed, 12 Apr 2017 00:44:27 +0100 Subject: [PATCH] drm/i915: Wake device for emitting request during selftest igt_mmap_offset_exhaustion() selftest was using live requests to make an object busy, but we did not hold a runtime pm wakeref for submitting the requests. Acquire it to avoid triggering "RPM wakelock ref not held during HW access" warnings.
