6 QEMU CI pipelines can be tuned by setting some CI environment variables.
8 Set variable globally in the user's CI namespace
9 ------------------------------------------------
11 Variables can be set globally in the user's CI namespace setting.
13 For further information about how to set these variables, please refer to::
15 https://docs.gitlab.com/ee/ci/variables/#add-a-cicd-variable-to-a-project
17 Set variable manually when pushing a branch or tag to the user's repository
18 ---------------------------------------------------------------------------
20 Variables can be set manually when pushing a branch or tag, using
21 git-push command line arguments.
23 Example setting the QEMU_CI_EXAMPLE_VAR variable:
27 git push -o ci.variable="QEMU_CI_EXAMPLE_VAR=value" myrepo mybranch
29 For further information about how to set these variables, please refer to::
31 https://docs.gitlab.com/ee/user/project/push_options.html#push-options-for-gitlab-cicd
33 Setting aliases in your git config
34 ----------------------------------
36 You can use aliases to make it easier to push branches with different
37 CI configurations. For example define an alias for triggering CI:
41 git config --local alias.push-ci "push -o ci.variable=QEMU_CI=1"
42 git config --local alias.push-ci-now "push -o ci.variable=QEMU_CI=2"
50 to create the pipeline, or:
56 to create and run the pipeline
59 Variable naming and grouping
60 ----------------------------
62 The variables used by QEMU's CI configuration are grouped together
63 in a handful of namespaces
65 * QEMU_JOB_nnnn - variables to be defined in individual jobs
66 or templates, to influence the shared rules defined in the
69 * QEMU_CI_nnn - variables to be set by contributors in their
70 repository CI settings, or as git push variables, to influence
71 which jobs get run in a pipeline
73 * QEMU_CI_CONTAINER_TAG - the tag used to publish containers
74 in stage 1, for use by build jobs in stage 2. Defaults to
75 'latest', but if running pipelines for different branches
76 concurrently, it should be overridden per pipeline.
78 * QEMU_CI_UPSTREAM - gitlab namespace that is considered to be
79 the 'upstream'. This defaults to 'qemu-project'. Contributors
80 may choose to override this if they are modifying rules in
81 base.yml and need to validate how they will operate when in
82 an upstream context, as opposed to their fork context.
84 * nnn - other misc variables not falling into the above
85 categories, or using different names for historical reasons
86 and not yet converted.
88 Maintainer controlled job variables
89 -----------------------------------
91 The following variables may be set when defining a job in the
92 CI configuration file.
97 The job makes use of Cirrus CI infrastructure, requiring the
98 configuration setup for cirrus-run to be present in the repository
103 The job is expected to be successful in general, but is not run
104 by default due to need to conserve limited CI resources. It is
105 available to be started manually by the contributor in the CI
111 The job results are only of interest to contributors prior to
112 submitting code. They are not required as part of the gating
118 The job is not reliably successful in general, so is not
119 currently suitable to be run by default. Ideally this should
120 be a temporary marker until the problems can be addressed, or
121 the job permanently removed.
126 The job is for publishing content after a branch has been
127 merged into the upstream default branch.
132 The job runs the Avocado integration test suite
134 Contributor controlled runtime variables
135 ----------------------------------------
137 The following variables may be set by contributors to control
143 By default, no pipelines will be created on contributor forks
144 in order to preserve CI credits
146 Set this variable to 1 to create the pipelines, but leave all
147 the jobs to be manually started from the UI
149 Set this variable to 2 to create the pipelines and run all
150 the jobs immediately, as was the historical behaviour
152 QEMU_CI_AVOCADO_TESTING
153 ~~~~~~~~~~~~~~~~~~~~~~~
154 By default, tests using the Avocado framework are not run automatically in
155 the pipelines (because multiple artifacts have to be downloaded, and if
156 these artifacts are not already cached, downloading them make the jobs
157 reach the timeout limit). Set this variable to have the tests using the
158 Avocado framework run automatically.
163 These variables are primarily to control execution of jobs on
166 AARCH64_RUNNER_AVAILABLE
167 ~~~~~~~~~~~~~~~~~~~~~~~~
168 If you've got access to an aarch64 host that can be used as a gitlab-CI
169 runner, you can set this variable to enable the tests that require this
170 kind of host. The runner should be tagged with "aarch64".
172 AARCH32_RUNNER_AVAILABLE
173 ~~~~~~~~~~~~~~~~~~~~~~~~
174 If you've got access to an armhf host or an arch64 host that can run
175 aarch32 EL0 code to be used as a gitlab-CI runner, you can set this
176 variable to enable the tests that require this kind of host. The
177 runner should be tagged with "aarch32".
179 S390X_RUNNER_AVAILABLE
180 ~~~~~~~~~~~~~~~~~~~~~~
181 If you've got access to an IBM Z host that can be used as a gitlab-CI
182 runner, you can set this variable to enable the tests that require this
183 kind of host. The runner should be tagged with "s390x".
187 The jobs are configured to use "ccache" by default since this typically
188 reduces compilation time, at the cost of increased storage. If the
189 use of "ccache" is suspected to be hurting the overall job execution
190 time, setting the "CCACHE_DISABLE=1" env variable to disable it.
