| lts-triage.py |
| ============= |
| |
| Purpose of this script is to check a patch and determine if that patch qualifies |
| as a candidate for one of the LTS branches. |
| |
| Currently it focuses on cpu errata while it contains basic support for security |
| patches. It computes a crude score: |
| |
| 1 point if subject line matches tokens for cpu errata or security |
| 1 point for "report_errata ERRATA" in a lib/cpus/aarch{32,64}/*.S file |
| 1 point for "- ``ERRATA_" in docs/design/cpu-specific-build-macros.rst file |
| |
| Note that the script only looks at commits which are not merge commits. |
| |
| Running it: |
| ----------- |
| |
| To run it, provide it a path to a TF-A git repo. Here's help output for convenience: |
| |
| $ python lts/lts-triage.py -h |
| usage: lts-triage.py [-h] --repo REPO [--branch BRANCH] [--sample_size SAMPLE_SIZE] [--debug] |
| |
| check patches for LTS candidacy |
| |
| options: |
| -h, --help show this help message and exit |
| --repo REPO path to tf-a git repo |
| --branch BRANCH branch to check. default = integration |
| --sample_size SAMPLE_SIZE |
| how many patches to scan. default = 20 |
| --debug print debug logs |
| |
| Below is an example output. On left is commit hash of each of the commits |
| observed by this script and on right is score assigned to it. |
| |
| $ python lts/lts-triage.py --repo ../trusted-firmware-a/ |
