Hello all, I am doing some quality improvements for a couple of the em28xx/saa7113 designs, and I found a pretty serious problem which appears to have been there for some time. In fact, the regression was introduced when the saa7115 support was added in 2005 (hg revision 2750). This change resulted in the anti-alias filtering being disabled by default for the saa7113 (the saa7115_init_misc block clears bit 7 of register 0x02). Without this change, vertical lines appear in the chroma on a fixed interval. The big issue is that the driver is shared with other saa7113 products, as well as products that have the saa7111, saa7114, and saa7115. So I have to figure out whether to just force on the AA filter for the saa7113, or whether it should be enabled for the others, or whether I can even turn it on for saa7113 in general or need to hack something in there to only do it for the two or three products I am testing with. So here's where I could use some help: If you have a product that uses one of the above chips, please speak up. I will be setting up a test tree where people can try out the change and see if it makes their situation better, worse, or no change. Devin -- Devin J.
