buildman: Incorporate the genboardscfg.py tool

2022-08-05T15:47:56Z

Bring this tool into buildman, so we don't have to run it separately. The board.cfg file is still produced as part of the build, to save time when doing another build in the same working directory. If it is out of date with respect to the Kconfig, it is updated. Time to regenerate on a recent single-thread machine is 4.6s (1.3s on a 32-thread machine), so we do need some sort of cache if we want buildman to be useful on incremental builds. We could use Python's pickle format but: - it seems useful to allow boards.cfg to be regenerated, at least for a while, in case other tools use it - it is possible to grep the file easily, e.g. to find boards which use a particular SoC (similar to 'buildman -nv ' Signed-off-by: Simon Glass Suggested-by: Tom Rini

buildman: Support running from an IDE

2022-08-05T15:47:55Z

Add a flag to allow buildman to behave properly for use from an IDE. This shows error/warning output on stderr and drops all summary and progress information. This should normally only be used when building a single board. Fix up a confusing comment for GetResultSummary() while we are here, since we want to use the Outcome object to access the unprocessed error lines from the build. Signed-off-by: Simon Glass

buildman: Drop -I option

2022-08-05T15:47:55Z

This has been deprecated with a notice that it will be removed after April 2021. Drop it now. Signed-off-by: Simon Glass

buildman: Allow adjusting board config on the fly

2022-02-09T04:07:59Z

Add a -a option to specify changes to the config before the build commences. For example buildman -a ~CONFIG_CMDLINE disables CONFIG_CMDLINE before doing the build. This makes it easier to try things out as well as to write tests without creating a new board or manually manging the .config file. Signed-off-by: Simon Glass

buildman: Add a flag to control the traceback

2022-02-09T04:07:59Z

At present the full horror of the Python traceback is shown by default. It is normally only useful for debugging. Turn it off by default and add a --debug flag to enable it. Signed-off-by: Simon Glass

buildman: Support single-threaded operation

2021-03-04T22:51:43Z

At present even if only a single thread is in use, buildman still uses threading. For some debugging it is helpful to do everything in the main process. Allow -T0 to support this. Signed-off-by: Simon Glass

buildman: Make sure that -o is given with -w

2020-04-26T20:24:08Z

It is a bad idea to use the default output directory ('..') with -w since it does a build in that directory and writes various files these. Require that -o is given to avoid this problem. Signed-off-by: Simon Glass

buildman: Add an option to ignore migration warnings

2020-04-21T12:33:47Z

These are becoming more common now. They cause boards to show warnings which can be mistaking for compiler warnings. Add a buildman option to ignore them. This option works only with the summary option (-s). It does not affect the build process. Signed-off-by: Simon Glass

buildman: Add an option to ignore device-tree warnings

2020-04-21T12:33:47Z

Unfortunately the plague of device-tree warnings has not lifted. These warnings infiltrate almost every build, adding noise and confusion. Add a buildman option to ignore them. This option works only with the summary option (-s). It does not affect the build process. Signed-off-by: Simon Glass

buildman: Make -I the default

2020-04-21T12:33:47Z

At present buildman defaults to running 'mrproper' on every thread before it starts building commits for each board. This can add a delay of about 5 seconds to the start of the process, since the tools and other invariants must be rebuilt. In particular, a build without '-b', to build current source, runs much slower without -I, since any existing build is removed, thus losing the possibility of an incremental build. Partly this behaviour was to avoid strange build-system problems caused by running 'make defconfig' for one board and then one with a different architecture. But these problems were fixed quite a while ago. The -I option (which disabled mrproper) was introduced four years ago and does not seem to cause any problems with builds. So make -I the default and deprecate the option. To allow use of 'mrproper', add a new -m flag. Signed-off-by: Simon Glass
