Hi all,

I think it is getting time for people to start testing the ivtv trunk 
from subversion. I've been running it for quite some time now and it 
looks to be pretty solid. Ian Armstrong has added lots of goodies in 
the framebuffer department (be sure to read the README notes!), so that 
can use some testing as well.

Regarding DMA problems: I think that these are solved for the PVR500. I 
haven't yet done a REALLY long duration test but from the shorter tests 
I did it is looking good. The DMA errors still occur for other cards: 
it is a hardware issue with the cx23415/6 and there probably isn't 
anything I can do about it. Just don't use CPU freq. changers and 
sometimes using a RAID array also messes up the DMA.

The reason that it works for the PVR500 is that the PVR500 has a PCI 
bridge that seems to isolate the cx23416 chips from the main PCI bus. 
It still could fail on the 0.9 drivers due to the way DMA was handled 
in the driver. With the new trunk driver all DMA is now done in the 
interrupt handler.

Note: ivtv trunk requires the 2.6.19 kernel. It is probably very easy to 
backport it to 2.6.18, it may even compile out of the box. I just 
haven't tested it myself. When this driver version is released I'll 
definitely backport it to 2.6.18.

The trunk driver can be obtained here:

Thanks,
