Hi @saitejx08, to make sure I understand this will emulate ppc64le on the GitHub-hosted runner just like it does for s390x, is that correct?

[saitejx08]

Yes, @kyguy that is exactly correct.

My change just adds ppc64le to the existing hw_platform matrix, so it will use the same QEMU emulation (through the existing tonistiigi/binfmt and docker run --platform steps) that was already in place for the s390x build.

Thanks for checking!

[kyguy]

Thanks for the explanation @saitejx08, that should work fine!

[kyguy]

These CI changes look fine, we just need a maintainer to approve and merge.

[saitejx08]

Sounds good @kyguy, Thanks for the review.
