| Theory of Operation |
| |
| Please see README for user documentation, and you should be familiar with |
| that before trying to make sense of this. |
| |
| Buildman works by keeping the machine as busy as possible, building different |
| commits for different boards on multiple CPUs at once. |
| |
| The source repo (self.git_dir) contains all the commits to be built. Each |
| thread works on a single board at a time. It checks out the first commit, |
| configures it for that board, then builds it. Then it checks out the next |
| commit and builds it (typically without re-configuring). When it runs out |
| of commits, it gets another job from the builder and starts again with that |
| board. |
| |
| Clearly the builder threads could work either way - they could check out a |
| commit and then built it for all boards. Using separate directories for each |
| commit/board pair they could leave their build product around afterwards |
| also. |
| |
| The intent behind building a single board for multiple commits, is to make |
| use of incremental builds. Since each commit is built incrementally from |
| the previous one, builds are faster. Reconfiguring for a different board |
| removes all intermediate object files. |
| |
| Many threads can be working at once, but each has its own working directory. |
| When a thread finishes a build, it puts the output files into a result |
| directory. |
| |
| The base directory used by buildman is normally '../<branch>', i.e. |
| a directory higher than the source repository and named after the branch |
| being built. |
| |
| Within the base directory, we have one subdirectory for each commit. Within |
| that is one subdirectory for each board. Within that is the build output for |
| that commit/board combination. |
| |
| Buildman also create working directories for each thread, in a .bm-work/ |
| subdirectory in the base dir. |
| |
| As an example, say we are building branch 'us-net' for boards 'sandbox' and |
| 'seaboard', and say that us-net has two commits. We will have directories |
| like this: |
| |
| us-net/ base directory |
| 01_g4ed4ebc_net--Add-tftp-speed-/ |
| sandbox/ |
| u-boot.bin |
| seaboard/ |
| u-boot.bin |
| 02_g4ed4ebc_net--Check-tftp-comp/ |
| sandbox/ |
| u-boot.bin |
| seaboard/ |
| u-boot.bin |
| .bm-work/ |
| 00/ working directory for thread 0 (contains source checkout) |
| build/ build output |
| 01/ working directory for thread 1 |
| build/ build output |
| ... |
| u-boot/ source directory |
