From edb084f487a3b7c86efce81bfa1a7aa666dd4047 Mon Sep 17 00:00:00 2001 From: Dennis Li Date: Wed, 2 Sep 2020 17:11:09 +0800 Subject: [PATCH] drm/amdkfd: fix a memory leak issue In the resume stage of GPU recovery, start_cpsch will call pm_init which set pm->allocated as false, cause the next pm_release_ib has no chance to release ib memory. Add pm_release_ib in stop_cpsch which will be called in the suspend stage of GPU recovery.
