I'm sure everyone has their own ideas of what it is for their own needs, but this thread shows a clear separation between the original writers and people working on supporting their own platforms. So, my suggestion - also so I can understand it, since I kinda need it now for the atheros mips ports! - is maybe something gets written up in the wiki that's a more detailed technical overview of intrng, including the problems its trying to solve. Then, instead of flinging things around on the commit mailing list, people edit the wiki and discuss on -arm about the specific details. I think that'll avoid a lot of what's going on. (And honestly, I'd like it more sorted out sooner rather than later, as I really want to start attacking the QCA ARM ports (IPQ4019) if it's not already done, and that's all interrupt/gpio/etc gymnastics we need INTRNG for.) So, Nathan, wanna start a wiki page with the /current/ implementation that's in -HEAD and what the intention was from the PPC side? -adrian
