From 72022a705e1da854653e56b67bef57b72f1392eb Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Thu, 30 Mar 2017 15:50:38 +0100 Subject: [PATCH] drm/i915: Move retire-requests into i915_gem_wait_for_idle() As we now distinguish everywhere that can call i915_gem_retire_requests() following a successful wait_for_idle, we can remove the duplication by moving that call into i915_gem_wait_for_idle() itself.
