Subject: [patch v2 04/10] drivers/video/rockchip/rk_vop.c: Reserve efi fb memory
Date: Tue, 27 Oct 2020 14:21:35 +0100 [thread overview]
Message-ID: <20201027132235.883717675@rtp-net.org> (raw)
In-Reply-To: 20201027132131.016984025@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.
