Subject: [patch 5/8] RFC: drivers/video/rockchip/rk_vop.c: Reserve efi fb memory
Date: Fri, 25 Sep 2020 20:36:59 +0200 [thread overview]
Message-ID: <20200925183856.548086571@rtp-net.org> (raw)
In-Reply-To: 20200925183654.723338620@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.
