Definitely. We've gotten a few bug reports for FreeBSD on PowerVM, so we definitely have some interest by others. I'd love to get my hands on some PowerVM hardware myself just to play with, but haven't managed to do that. >=20 > * > Where should we publish the current work and start submitting patches? You could submit patches to https://reviews.freebsd.org, we also have a GitHub presence, and https://bugs.freebsd.org is another, but you'd get more traction on Phabricator and GitHub. >=20 > * > Would a short technical summary of the blockers, changes and test > results be a useful first step?
