Subject: [PATCH AUTOSEL 4.19 019/206] drm/amdgpu/powerplay: fix AVFS handling with custom powerplay table
Date: Thu, 17 Sep 2020 22:04:55 -0400 [thread overview]
Message-ID: <20200918020802.2065198-19-sashal@kernel.org> (raw)
In-Reply-To: <20200918020802.2065198-1-sashal@kernel.org>
From: Alex Deucher <alexander.deucher@amd.com>
[ Upstream commit 53dbc27ad5a93932ff1892a8e4ef266827d74a0f ]
When a custom powerplay table is provided, we need to update
the OD VDDC flag to avoid AVFS being enabled when it shouldn't be.
