From cc85345dc804f9fbe39ca2727e63058595b01e0f Mon Sep 17 00:00:00 2001 From: Umesh Nerlige Ramappa Date: Wed, 26 Oct 2022 22:20:55 +0000 Subject: [PATCH] drm/i915/perf: Use gt-specific ggtt for OA and noa-wait buffers User passes uabi engine class and instance to the perf OA interface. Use gt corresponding to the engine to pin the buffers to the right ggtt.
