Subject: [PATCH AUTOSEL 5.8 12/20] drm/amdkfd: fix a memory leak issue
Date: Mon, 21 Sep 2020 10:40:19 -0400 [thread overview]
Message-ID: <20200921144027.2135390-12-sashal@kernel.org> (raw)
In-Reply-To: <20200921144027.2135390-1-sashal@kernel.org>
From: Dennis Li <Dennis.Li@amd.com>
[ Upstream commit 087d764159996ae378b08c0fdd557537adfd6899 ]
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.
