In our implementation, we have the hook to use Sun's DGA (Direct
Graphics Access) library to render locally on a Sparc station.
Currently, only the framebuffers FFB and CG6 have the DGA support
readily implemented. The Ultra 1 Creator 3D has the FFB. Some other
third party vendors also have added DGA support for their framebuffer
devices on Sparc stations.
The rendering pipeline checks for the existence of the DGA support in
the form of a shared library for the target framebuffer. If the support
(shared library file) doesn't exist, then X11 is used to render
instead. For the FFB and CG6, the correspondent files are
`libjdgaSUNWffb.so' and `libjdgaSUNWcg6.so' in Java 2.
Note that the DGA support only maps the framebuffer into memory to
render. Any other acceleration features in the hardware are not being
taken advantage of in the current release. There is certainly plan to
leverage more hardware acceleration features, but I don't know which
future release would have the implementation.
Thanks.
