| # Testing | ||
|
|
||
| > [!NOTE] | ||
| > This is a copy of the s390x self-hosted action runner scripts from | ||
| > https://github.com/zlib-ng/zlib-ng/tree/a0fa24710c8faa1a746a20cfd5c7c24571e15ca4/arch/s390/self-hosted-builder | ||
|
|
||
| Given complexity of DFLTCC machine instruction, it is not clear whether | ||
| QEMU TCG will ever support it. At the time of writing, one has to have | ||
| access to an IBM z15+ VM or LPAR in order to test DFLTCC support. Since | ||
| DFLTCC is a non-privileged instruction, neither special VM/LPAR | ||
| configuration nor root are required. | ||
|
|
||
| zlib CI uses a self-hosted builder, provided by marist university | ||
| for the DFLTCC testing. There is no official IBM Z GitHub Actions runner, | ||
| so we build one inspired by `anup-kodlekere/gaplib`. | ||
| Future updates to actions-runner might need an updated patch. The .net | ||
| version number patch has been separated into a separate file to avoid a | ||
| need for constantly changing the patch. | ||
|
|
||
| ## Configuring the builder. | ||
|
|
||
| ### Install prerequisites. | ||
| ``` | ||
| sudo dnf install podman | ||
| ``` | ||
|
|
||
| ### Create a config file, needs github personal access token. | ||
| Access token needs permissions; Repo Admin RW, Org Self-hosted runners RW. | ||
| For details, consult | ||
| https://docs.github.com/en/rest/actions/self-hosted-runners?apiVersion=2022-11-28#create-a-registration-token-for-a-repository | ||
|
|
||
| #### Create file /etc/actions-runner: | ||
| ``` | ||
| REPO=<owner>/<name> | ||
| PAT_TOKEN=<github_pat_***> | ||
| ``` | ||
|
|
||
| #### Set permissions on /etc/actions-runner: | ||
| ``` | ||
| chmod 0600 /etc/actions-runner | ||
| ``` | ||
|
|
||
| ### Add actions-runner service. | ||
| ``` | ||
| sudo cp self-hosted-builder/actions-runner.service /etc/systemd/system/ | ||
| sudo systemctl daemon-reload | ||
| ``` | ||
|
|
||
| ### Autostart actions-runner. | ||
| ``` | ||
| $ sudo systemctl enable --now actions-runner | ||
| ``` | ||
|
|
||
| ### Add auto-rebuild cronjob | ||
| ``` | ||
| sudo cp self-hosted-builder/actions-runner-rebuild.sh /etc/cron.weekly/ | ||
| chmod +x /etc/cron.weekly/actions-runner-rebuild.sh | ||
| ``` | ||
|
|
||
| ## Building / Rebuilding the container | ||
| ``` | ||
| sudo /etc/cron.weekly/actions-runner-rebuild.sh | ||
| ``` |
