The concurrencykit website mentions ARM and MIPS as future ports. Is this actually true? Is concurrencykit supposed to actually run on ARM/MIPS? Did anyone test? Actual MIPS hardware that we run on is like $50. It's not exactly spendy to test out FreeBSD code on real hardware. :) I can't even build the regression suite from CK on github to run on mips32 hardware. I don't suppose anyone would be able to figure that particular mess out? I'd really like to work some more on wifi stack stuff on this embedded platform stuff and this just threw a spanner in my plans. I'd really appreciate some help here cause I don't have time to wade through more platform breakage just to do wifi stack / driver work. I have limited spare time as it is these days :( Thanks, -adrian
