From 8814c6d01f7e82e6be70ac04d8bca0fc90757418 Mon Sep 17 00:00:00 2001 From: Lionel Landwerlin Date: Sun, 20 Oct 2019 00:46:47 +0300 Subject: [PATCH] drm/i915/perf: fix oa config reconfiguration The current logic just reapplies the same configuration already stored into stream->oa_config instead of the newly selected one.
