Subject: [PATCH 3/3] drm/amdgpu:Limit the resolution for virtual_display
Date: Wed, 6 Jan 2021 09:05:15 +0800 [thread overview]
Message-ID: <20210106010515.486545-3-Emily.Deng@amd.com> (raw)
In-Reply-To: <20210106010515.486545-1-Emily.Deng@amd.com>
Limit the resolution not bigger than 16384, which means
dev->mode_info.num_crtc * common_modes[i].w not bigger than 16384.
