I have an upcomming project thats going to require the addition of NTSC video overlays to a display system with 2 Assiliant (C&T) 69000s running in multi-head.
We have an existing product that does this with a saa7111a connected directly to a 69000. It runs a DOS program where the control of the saa7111a is done from the 69000 via I2C. Since we have a somewhat proven design we would like to just splat these circuits onto our other 69000 system. However, it's not yet obvious to me how to control the 7111a from the 69000s under X. I've been going over the I2C code and so far it looks like its specifically for getting DDC info. In fact there is a statement in the 69000 drivers comments suggests that the only thing expected to be on the 69000's I2C bus is DDC info. Is this the whole story? If so would we be better off attaching the saa7111s to the SMBus and using the kernel I2C stuff? And then on the 69000 side what would be the prefered method to talk to the internal registers on the 69000 for when I want to set up the overlays? Can XVideo control stuff like this? My google searches so far haven't really yeilded any usefull info. -- Richard A. Smith Bitworks, Inc.
