This is the ARM Linux Kernel Autobuild (Kautobuild) system. This system retrieves the latest available stable kernel source from kernel.org and builds all the available default configurations.
This retrieval includes building the release candidates and daily Git snapshots. The results of each build are placed in a database and made available for query through this interface. In addition a mailing list is available where the results are mailed when available.
The history of the builds has been made accesible through the statistics interface a complete list of past kernels built is also available. The complete list of every configuration ever attempted in any build is also available.
