Subject: [PATCH 1/4] drm/amdgpu: Macros for vram physical addr calculation
Date: Tue, 30 Mar 2021 14:35:30 -0500 [thread overview]
Message-ID: <1617132933-16843-1-git-send-email-Oak.Zeng@amd.com> (raw)
Add one macro to calculate BO's GPU physical address.
And another one to calculate BO's CPU physical address.
