Collaboration with @tiborvass at Docker who got Docker running on big-endian PPC64. Go for ppc64 doesn't support cgo or external linking, so runc doesn't work, but a new OCI-compliant runc implementation written in C (https://github.com/containers/crun) means we can run Docker after all. See NOTES & build-*.sh Then add a Dockerfile & associated cleanup in buildlet & stage0 to use rundockerbuildlet. Once done, might help with golang/go#35188, golang/go#32613, etc. Fixes golang/go#34830 Updates golang/go#21260 Change-Id: I43d7afa1d58bbdfa16e3c57670bc41f1d1932d80 Reviewed-on: https://go-review.googlesource.com/c/build/+/203886 Reviewed-by: Brad Fitzpatrick <bradfitz@golang.org>

I don't see the deadlocks for a while. Looks like it's gone. |
Thanks, closing. We've fixed several potentially deadlock causing bugs in the last few weeks. |
