From 539de4f96970091637ca6df1da1e314f89f5657d Mon Sep 17 00:00:00 2001 From: Joseph Greathouse Date: Wed, 17 Jul 2019 09:47:58 -0500 Subject: [PATCH 2996/4256] drm/amdkfd: Remove GWS from process during uninit If we shut down a process without having destroyed its GWS-using queues, it is possible that GWS BO will still be in the process BO list during the gpuvm destruction. This list should be empty at that time, so we should remove the GWS allocation at the process uninit point if it is still around.
