From 5bd11a34e46afa1048bd5330673fb1508183f6a5 Mon Sep 17 00:00:00 2001 From: Imre Deak Date: Mon, 7 Nov 2016 11:20:02 +0200 Subject: [PATCH] drm/i915: Avoid early GPU idling due to already pending idle work Atm, in case an idle work handler is already pending but haven't yet started to run, retiring a new request will not extend the active period as required, rather simply leaves the pending idle work to be scheduled at the original expiration time. This may lead to idling the GPU too early. Fix this by using the delayed-work scheduler alternative which makes sure the handler's expiration time is extended in this case.
