Configuration reference

This document is a reference for options available in the KernelCI pipeline config file.

Jobs configuration

Parameter frequency (optional)

• Value: [Nd][Nh][Nm]
• Default: none (no limit)

The frequency parameter is used to limit frequency of job execution. It is specified as a string with a number of days, hours and minutes. For example, 1d2h30m means that the job can only be executed once every day, 2 hours and 30 minutes. Job frequency is calculated to particular tree/branch, so if you have a job that runs on multiple branches, it will be executed independently for each branch.

Example:

jobs:

  baseline-arm64-mediatek: &baseline-job
    template: baseline.jinja2
    kind: job
    kcidb_test_suite: boot
    params:
      frequency: 1h

Rules (optional)

We have a set of rules that can be used to filter jobs based on different criteria.

tree:

• Value: [!]string(tree name) or string:string (tree name:branch name)
• Default: none (no limit)

Tree and branch rules can be formatted as <tree>:<branch>, meaning only a given branch is allowed for a specific tree. When prepended with !, it indicates a forbidden tree/branch combination.

min_version:

• Value: version: int, patchlevel: int
• Default: none (no limit)

This rule allows to filter jobs based on the kernel version. The version field is the major version of the kernel, and the patchlevel field is the minor version. For example, version: 4, patchlevel: 19 will only allow jobs for kernel versions 4.19 and above.

max_version:

• Value: version: int, patchlevel: int
• Default: none (no limit)

This rule allows to filter jobs based on the kernel version. The version field is the major version of the kernel, and the patchlevel field is the minor version. For example, version: 4, patchlevel: 19 will only allow jobs for kernel versions 4.19 and below.

    rules:
      tree:
      - '!android'

This will exclude all jobs from the ‘android’ tree.

    rules:
      min_version:
        version: 4
        patchlevel: 19
      tree:
      - 'next'
      - 'sashal-next'

This will only allow jobs from the ’next’ and ‘sashal-next’ trees with kernel version 4.19 and above.

    rules:
      tree:
      - 'kernelci:staging-next'

This will only allow jobs from the ‘staging-next’ branch of the ‘kernelci’ tree.

  rules:
    min_version:
      version: 6
      patchlevel: 1
    max_version:
      version: 6
      patchlevel: 6
    arch:
      - 'arm64'
    tree:
      - linus:master
      - stable
    branch:
      - '!stable:master'
    defconfig:
      - '!allnoconfig'
    fragments:
      - 'kselftest'
      - '!arm64-chromebook'

For example, the following rules definition mean the job can run only:

• with a kernel version between 6.1 and 6.6
• on arm64 devices
• when using a checkout from the master branch on the linus tree, or any branch except master on the stable tree
• if the kernel has been built with any defconfig except allnoconfig, using the kselftest fragment but not the arm64-chromebook one
