Compositing Engine GC320 on iMX6

[sunilpatil]

How to use 3rd GPU on iMX6 to merge results of the other GPUs?

Please provide pointers to information available.

Thanks.

You use DirectFB or direct gal2d APIs part of the GPU driver.

Does there is some source code available for the gal2d api?  There is some test application in the linux packages, but it look like the source code of the application is not available... There is a package named gpu-viv-src listed in ltib, but I cannot download it:

./ltib -m prep --pkg gpu-viv-src

Processing: gpu-viv-src

=========================

Build path taken because: build key set, no prebuilt rpm,

Testing network connectivity

OK GPP:

Try gpu-viv-src-1.1.0.tar.gz.md5 from the GPP

http://bitshrine.org/gpp/gpu-viv-src-1.1.0.tar.gz.md5:

16:53:38 ERROR 404: Not Found.

Try gpu-viv-src-1.1.0.tar.gz from the GPP

http://bitshrine.org/gpp/gpu-viv-src-1.1.0.tar.gz:

16:53:39 ERROR 404: Not Found.

Can't get: gpu-viv-src-1.1.0.tar.gz at ./ltib line 802.

Does the source code of the test application that is using the GC320 in fb mode is available?

Hello Eric,

Were you able to find source code examples for the gal2d API?  I've been looking with no luck.

Thank you,
