Hi, We're building .deb/.rpm packages for ARM by using QEMU on x86-64 machine: https://github.com/apache/arrow/blob/master/dev/tasks/linux-packages/azure.linux.arm64.yml#L36-L50
It's slow. Some jobs can't finish in 6h, Azure Pipelines build time limit. You can see some *-aarch64 and *-arm64 jobs are failed in https://github.com/apache/arrow/pull/6276#issuecomment-578006232 . (Especially building gRPC for Flight is slow.) It means that we can't build some .deb/.rpm packages for ARM by Crossbow. I can build them on my local machine for 0.16.0. Or we can just ignore these packages because we didn't support .deb/.rpm for ARM until 0.15.1. .deb/.rpm for ARM support is a new feature of 0.16.0. This is not a regression. So this is not a blocker of 0.16.0. I submitted a pull request to add support for GitHub Actions to Crossbow: https://github.com/apache/arrow/pull/6286 If we can use GitHub Actions by Crossbow, we can improve ARM package build performance by adding self-hosted GitHub Runner for ARM. See the following self-hosted GitHub Runner: https://help.github.com/en/actions/automating-your-workflow-with-github-actions/about-self-hosted-runners It seems that Ursa Labs has ARM machine: https://github.com/ursa-labs/ursabot/blob/master/workers.yaml#L113 Could you add the ARM machine to https://github.com/ursa-labs/crossbow/ ? Then we can use the ARM machine to build .deb/.rpm packages for ARM by Crossbow. Thanks, -- kou
