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_of_02_g4ed4ebc_net--Add-tftp-speed-/

force_config_on_failure: If a commit fails for a board, disable

incremental building for the next commit we build for that

a previous run of buildman) is marked as failed, rebuild it.

warned: Number of builds that produced at least one warning
|
|
force_reconfig: Reconfigure U-Boot on each comiit. This disables
|
|
incremental building, where buildman reconfigures on the first
|
|
commit for a baord, and then just does an incremental build for
|
|
the following commits. In fact buildman will reconfigure and
|
|
retry for any failing commits, so generally the only effect of
|
|
this option is to slow things down.
|
|
in_tree: Build U-Boot in-tree instead of specifying an output
|
|
directory separate from the source code. This option is really
|

only useful for testing in-tree builds.
