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 Thank you, Oleksandr Andrushchenko Oleksandr Grytsov Oleksandr Andrushchenko (1): displif: add ABI for para-virtual display xen/include/public/io/displif.h | 778 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 778 insertions(+) create mode 100644 xen/include/public/io/displif.h -- 2.7.4 _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org https://lists.xen.org/xen-devel
