Unfortunately that's a bit of a reach for me; I live in southern Ontario
and will be in New York City from September to December. So, I will
likely be unable to attend, though I'll certainly see if I can pull it
off. I'd be paying out of pocket for the travel, unfortunately.
I definitely want to contribute what I can to this project, both because
I want its result and because I want to learn more about GHC and the RTS.
As to waiting for 6.10, I won't be able to contribute much work here
before late August anyway, by which point much of 6.10 will likely be
solidified in the HEAD 6.9. Certainly there are experiments and other
parts of the project that can be worked on while waiting for the 6.10
release in late September.
I'll post the results of any experiments and any thoughts in the
GHC-on-ARM wiki. Notably, a page on what devices the developers have
comes to mind.
