From 5f5c382ecfdd06e17316d1c9f1362522c20cdfef Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Sat, 12 Oct 2019 10:10:56 +0100 Subject: [PATCH] drm/i915/perf: Prefer using the pinned_ctx for emitting delays on config When we are watching a particular context, we want the OA config to be applied inline with that context such that it takes effect before the next submission.
