[linuxsh-shmedia-dev] Support for Overlay surfaces using the Kyro framebuffer

[Gaster, B. <ben...@su...>]

Hello!

Most modern graphics cards provide support for what are often called
video overlay surfaces which provide functionality for colour
conversion, in particular YUV to RGB, and scaling from one resolution to
another. The Kyro chipset from Imagination Technologies is no exception
providing a wide selection of features for display video.=20

Recently we have added support for single overlay surfaces and views
(scaling) to simple Kyro framebuffer supported by the SHmedia Linux
kernel 2.4.19x (http://linux-shmedia.bkbits.net:8080/linux-2.4). As the
implementation requires use of some additional IOCTLS a small user
library has also been implemented and can be downloaded along with
documentation from the SuperH SHmedia Linux web site
(http://www.superh-software.com/linux/).
