This tool handles building U-Boot to check that you have not broken it with your patch series. It can build each individual commit and report which boards fail on which commits, and which errors come up. It also shows differences in image sizes due to particular commits. Buildman aims to make full use of multi-processor machines. Documentation and caveats are in tools/buildman/README. Signed-off-by: Simon Glass <sjg@chromium.org>

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-/
|
|
sandbox/

|

|

|
|

|
