Subject: [patch v4 4/9] Rockchip: video: vop: Reserve efi fb memory
Date: Fri, 05 Mar 2021 11:27:49 +0100 [thread overview]
Message-ID: <20210305103307.175518624@rtp-net.org> (raw)
In-Reply-To: 20210305102745.078091129@rtp-net.org
When booting with EFI and graphics, the memory used for framebuffer
has to be reserved, otherwise it may leads to kernel memory
overwrite.
