The DPDK Community Lab is an open, independent testing resource for the DPDK project. Its purpose is to perform automated testing which ensures that the performance and quality of DPDK is maintained.
Hardware for the lab is provided by equipment vendors and is used to run a series of performance tests on new patch sets. The results of these tests are published on the results dashboard which is publicly accessible, and are also integrated into the DPDK instance of Patchwork. The results will be used by the project's maintainers to help determine whether new patch sets should be accepted into the project.
The initial goal of the DPDK Community Lab is:
In future, the following additional items may be added to the scope of the lab:
There are two main components to the Dashboard; the Results Database and the Dashboard itself. All results are uploaded via the Results Database REST API. The Dashboard also uses the REST API to populate its pages. The REST API can only be accessed by participating members. Meta information, such as the series title and patch submitter, utilize the Patchwork REST API.
The Dashboard calls groups of related patches a Patch Set. This is equivalent to Patchwork's Series. In the Results Database, the model mostly contains build information and result summaries about the series. It also contains a link to the series itself to allow for grabbing meta information about the series.
Times for patches and tests are displayed in UTC time.
Relative performance is measured by comparing the actual result with the baseline result. The baseline itself is saved on the test machine; only the delta results are submitted. The database has the capability of saving the baseline in order to calculate an absolute result, but that must be explicitly requested by the participating member.
Fluctuation in these results are expected, hence a tolerance is set to determine if the result passes or fails.
