[PATCH v2 0/4] video: add support for QEMU ramfb

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



QEMU's ramfb is a very simple Qemu fw_cfg protocol, where the guest
need only write a video settings structure to /etc/ramfb to get
DMA from the framebuffer working. Add a driver for this on top
of a newly added character device interface.
