Zoran is a driver for old hardware. I don't doubt that are people out there still using it, but who knows? I have a few those boards packed somewhere. I haven't work with PCI hardware for a while. If needed, I can try to seek for them and do some tests. I need first to unpack a machine with PCI slots... the NUCs I generally use for development don't have any :-) Anyway, except for virt_to_bus() and related stuff, I think that this driver is in good shape, as Hans did a lot of work in the past to make it to use the current media framework. > > Trent, Hans: do you have reason to believe that there might still > be users out there? > > Arnd Thanks, Mauro
