I don't think this is the right way forward. : : I have to admit that I was quite pleasantly surprised that so many : network drivers became MPSAFE in the last couple of months, and USB : will nicely round that out. It may help if Ed could take whatever : notes he sent Peter about sio and drop them on the Wiki as the : beginning of a howto on adapting drivers to the new tty layer. One : thing I would really like to see is us taking this as an opportunity : to get more people interested in maintaining the tty drivers we have : -- now is a really good opportunity for people do adopt drivers and : update them. : : I fall down a bit more on the Warner side here also: I think posting : the docs in advance of removing the drivers, and having a couple of : weeks gap between those events, is a much more productive way to : achieve the goal of updated drivers. It also means that we don't : have timeline gaps when serial drivers for devices are broken: when : people are playing the binary search game to find some other : problem, the last thing they want is to hit dates where their system : consoles don't work. Yes. It wouldn't kill us to push this out 4-6 weeks. Having the docs available, even in the wiki form, would help quite a bit. We want to harvest the enthusiasm people like Peter and Peter are showing to convert their drivers. Warner
