From: Oleksandr Andrushchenko <oleksandr_andrushche...@epam.com>
This is the ABI for the two halves of a para-virtualized
display driver.
This protocol aims to provide a unified protocol which fits more
sophisticated use-cases than a framebuffer device can handle. At the
moment basic functionality is supported with the intention to extend:
o multiple dynamically allocated/destroyed framebuffers
o buffers of arbitrary sizes
o better configuration options including multiple display support
Note: existing fbif can be used together with displif running at the
same time, e.g. on Linux one provides framebuffer and another DRM/KMS
Future extensions to the existing protocol may include:
o allow display/connector cloning
o allow allocating objects other than display buffers
o add planes/overlays support
o support scaling
o support rotation
