CI Automation/windows10 aarch64
Overview
With the announcement of the Qualcomm-Mozilla partnership came the need to release a version of Firefox for the ARM64 architecture.
Since mid-January 2019 the CI-A team has been working to enable existing test harnesses, continuous integration tests and other tools to run on Windows 10 ARM64.
Information
Hardware
- Make: Lenovo
- Model: C630 YOGA
- Processor: Qualcomm Snapdragon 850 3.0GHz
- Cores: 8
- Memory: 8GB
- Disk: 128GB SSD
Hosting
Currently an array of 9 machines are hosted at Bitbar in the United States.
Setup
Tests that are run against windows10-aarch64 execute using Taskcluster Generic-Worker. These are installed as a service on the Windows 10 ARM64 manually or via OpenCloudConfig.
A brief walkthrough of the steps to have Taskcluster Generic-Worker running on Windows 10 ARM64 will be provided.
Using only generic-worker
Follow this step to install Taskcluster Generic-Worker on the hardware, and have it launch as a service. After following these steps, the hardware should be ready to accept any tasks started on Taskcluster.

Prerequisites
- disable Windows S mode
- disable User Account Control
- disable Windows Firewall
- download NSSM to C:\nssm-2.24\
- create "Remote Desktop Users" group:
* net localgroup "Remote Desktop Users" /add
- log in to Taskcluster
- request scope `assume:project:taskcluster:generic-worker-tester`
Steps
- download the current 386 release of `generic-worker-windows-386.exe` from taskcluster generic-worker.
- download the latest 386 version of livelog.exe and taskcluster-proxy.exe.
- create new directory C:\generic-worker.
- move the three executable files under C:\generic-worker.
- rename generic-worker-windows-386.exe to generic-worker.exe.
- generate two signing keys:
* generic-worker new-openpgp-keypair --file <unique_file_name> * generic-worker new-ed25519-keypair --file <unique_file_name>
- create generic-worker.config and include the following:
- launch cmd.exe with Administrator rights.
- cd c:\generic-worker
- generic-worker.exe install service --config generic-worker.config --nssm c:\nssm-2.24\win32\nssm.exe
- reboot once installed.
- launch cmd.exe with Administrator rights.
- sc query "Generic Worker"
