It can build each individual commit and report +which boards fail on which commits, and which errors come up. It aims +to make full use of multi-processor machines. + +A key feature of buildman is its output summary, which allows warnings, +errors or image size increases in a particular commit or board to be +quickly identified and the offending commit pinpointed. This can be a big +help for anyone working with >10 patches at a time. + + +Caveats +======= + +Buildman is still in its infancy. It is already a very useful tool, but +expect to find problems and send patches. + +Buildman can be stopped and restarted, in which case it will continue +where it left off. This should happen cleanly and without side-effects. +If not, it is a bug, for which a patch would be welcome. + +Buildman gets so tied up in its work that it can ignore the outside world. +You may need to press Ctrl-C several times to quit it. Also it will print +out various exceptions when stopped. + + +Theory of Operation +=================== + +(please read this section in full twice or you will be perpetually confused) + +Buildman is a builder. It is not make, although it runs make. It does not +produce any useful output on the terminal while building, except for +progress information. All the output (errors, warnings and binaries if you +are ask for them) is stored in output directories, which you can look at +while the build is progressing, or when it is finished. + +Buildman produces a concise summary of which boards succeeded and failed. +It shows which commit introduced which board failure using a simple +red/green colour coding. Full error information can be requested, in which +case it is de-duped and displayed against the commit that introduced the +error. An example workflow is below. + +Buildman stores image size information and can report changes in image size +from commit to commit. An example of this is below. + +Buildman starts multiple threads, and each thread builds for one board at +a time. A thread starts at the first commit, configures the source for your +board and builds it. Then it checks out the next commit and does an +incremental build. Eventually the thread reaches the last commit and stops. +If errors or warnings are found along the way, the thread will reconfigure +after every commit, and your build will be very slow. This is because a +file that produces just a warning would not normally be rebuilt in an +incremental build. + +Buildman works in an entirely separate place from your U-Boot repository. +It creates a separate working directory for each thread, and puts the +output files in the working directory, organised by commit name and board +name, in a two-level hierarchy. + +Buildman is invoked in your U-Boot directory, the one with the .git +directory. It clones this repository into a copy for each thread, and the +threads do not affect the state of your git repository. Any checkouts done +by the thread affect only the working directory for that thread. + +Buildman automatically selects the correct toolchain for each board. You +must supply suitable toolchains, but buildman takes care of selecting the +right one. + +Buildman always builds a branch, and always builds the upstream commit as +well, for comparison. It cannot build individual commits at present, unless +(maybe) you point it at an empty branch. Put all your commits in a branch, +set the branch's upstream to a valid value, and all will be well. Otherwise +buildman will perform random actions. Use -n to check what the random +actions might be. + +Buildman is optimised for building many commits at once, for many boards. +On multi-core machines, Buildman is fast because it uses most of the +available CPU power. When it gets to the end, or if you are building just +a few commits or boards, it will be pretty slow. As a tip, if you don't +plan to use your machine for anything else, you can use -T to increase the +number of threads beyond the default. + +Buildman lets you build all boards, or a subset. Specify the subset using +the board name, architecture name, SOC name, or anything else in the +boards.cfg file. So 'at91' will build all AT91 boards (arm), powerpc will +build all PowerPC boards. + +Buildman does not store intermediate object files. It optionally copies +the binary output into a directory when a build is successful. Size +information is always recorded. It needs a fair bit of disk space to work, +typically 250MB per thread. + + +Setting up +========== + +1. Get the U-Boot source. You probably already have it, but if not these +steps should get you started with a repo and some commits for testing. + +$ cd /path/to/u-boot +$ git clone git://git.denx.de/u-boot.git . +$ git checkout -b my-branch origin/master +$ # Add some commits to the branch, reading for testing + +2. Create ~/.buildman to tell buildman where to find tool chains. As an +example: + +# Buildman settings file + +[toolchain] +root: / +rest: /toolchains/* +eldk: /opt/eldk-4.2 + +[toolchain-alias] +x86: i386 +blackfin: bfin +sh: sh4 +nds32: nds32le +openrisc: or32 + + +This selects the available toolchain paths. Add the base directory for +each of your toolchains here. Buildman will search inside these directories +and also in any '/usr' and '/usr/bin' subdirectories. + +Make sure the tags (here root: rest: and eldk:) are unique. + +The toolchain-alias section indicates that the i386 toolchain should be used +to build x86 commits. + + +2. Check the available toolchains + +Run this check to make sure that you have a toolchain for every architecture. + +$ ./tools/buildman/buildman --list-tool-chains +Scanning for tool chains + - scanning path '/' + -

Each thread will run with -j1, meaning that each +make job will use a single CPU. The list of commits to be built helps you +confirm that things look about right. Notice that buildman has chosen a +'base' directory for you, immediately above your source tree. + +Buildman works entirely inside the base directory, here ../lcd9b, +creating a working directory for each thread, and creating output +directories for each commit and board. + + +Suggested Workflow +================== + +To run the build for real, take off the -n: + +$ ./tools/buildman/buildman -b <branch> + +Buildman will set up some working directories, and get started. After a +minute or so it will settle down to a steady pace, with a display like this: + +Building 18 commits for 1059 boards (4 threads, 1 job per thread) + 528 36 124 /19062 1:13:30 : SIMPC8313_SP + +This means that it is building 19062 board/commit combinations. So far it +has managed to succesfully build 528. Another 36 have built with warnings, +and 124 more didn't build at all. Buildman expects to complete the process +in an hour and 15 minutes. Use this time to buy a faster computer. + + +To find out how the build went, ask for a summary with -s. You can do this +either before the build completes (presumably in another terminal) or or +afterwards. Let's work through an example of how this is used: + +$ ./tools/buildman/buildman -b lcd9b -s +... +01: Merge branch 'master' of git://git.denx.de/u-boot-arm + powerpc: + galaxy5200_LOWBOOT +02: tegra: Use const for pinmux_config_pingroup/table() +03: tegra: Add display support to funcmux +04: tegra: fdt: Add pwm binding and node +05: tegra: fdt: Add LCD definitions for Tegra +06: tegra: Add support for PWM +07: tegra: Add SOC support for display/lcd +08: tegra: Add LCD driver +09: tegra: Add LCD support to Nvidia boards +10: arm: Add control over cachability of memory regions +11: lcd: Add CONFIG_LCD_ALIGNMENT to select frame buffer alignment +12: lcd: Add support for flushing LCD fb from dcache after update + arm: + lubbock +13: tegra: Align LCD frame buffer to section boundary +14: tegra: Support control of cache settings for LCD +15: tegra: fdt: Add LCD definitions for Seaboard +16: lcd: Add CONFIG_CONSOLE_SCROLL_LINES option to speed console +17: tegra: Enable display/lcd support on Seaboard +18: wip + +This shows which commits have succeeded and which have failed. In this case +the build is still in progress so many boards are not built yet (use -u to +see which ones). But still we can see a few failures. The galaxy5200_LOWBOOT +never builds correctly. This could be a problem with our toolchain, or it +could be a bug in the upstream. The good news is that we probably don't need +to blame our commits. The bad news is it isn't tested on that board. + +Commit 12 broke lubbock. That's what the '+ lubbock' means. The failure +is never fixed by a later commit, or you would see lubbock again, in green, +without the +. + +To see the actual error: + +$ ./tools/buildman/buildman -b <branch> -se lubbock +... +12: lcd: Add support for flushing LCD fb from dcache after update + arm: + lubbock ++common/libcommon.o: In function `lcd_sync': ++/u-boot/lcd9b/.bm-work/00/common/lcd.c:120: undefined reference to `flush_dcache_range' ++arm-none-linux-gnueabi-ld: BFD (Sourcery G++ Lite 2010q1-202) 2.19.51.20090709 assertion fail /scratch/julian/2010q1-release-linux-lite/obj/binutils-src-2010q1-202-arm-none-linux-gnueabi-i686-pc-linux-gnu/bfd/elf32-arm.c:12572 ++make: *** [/u-boot/lcd9b/.bm-work/00/build/u-boot] Error 139 +13: tegra: Align LCD frame buffer to section boundary +14: tegra: Support control of cache settings for LCD +15: tegra: fdt: Add LCD definitions for Seaboard +16: lcd: Add CONFIG_CONSOLE_SCROLL_LINES option to speed console +-/u-boot/lcd9b/.bm-work/00/common/lcd.c:120: undefined reference to `flush_dcache_range' ++/u-boot/lcd9b/.bm-work/00/common/lcd.c:125: undefined reference to `flush_dcache_range' +17: tegra: Enable display/lcd support on Seaboard +18: wip + +So the problem is in lcd.c, due to missing cache operations. This information +should be enough to work out what that commit is doing to break these +boards. (In this case pxa did not have cache operations defined). + +If you see error lines marked with - that means that the errors were fixed +by that commit. Sometimes commits can be in the wrong order, so that a +breakage is introduced for a few commits and fixed by later commits. This +shows up clearly with buildman. You can then reorder the commits and try +again. + +At commit 16, the error moves - you can see that the old error at line 120 +is fixed, but there is a new one at line 126. This is probably only because +we added some code and moved the broken line futher down the file. + +If many boards have the same error, then -e will display the error only +once. This makes the output as concise as possible. + +The full build output in this case is available in: + +../lcd9b/12_of_18_gd92aff7_lcd--Add-support-for/lubbock/ + + done: Indicates the build was done, and holds the return code from make. + This is 0 for a good build, typically 2 for a failure. + + err: Output from stderr, if any. Errors and warnings appear here. + + log: Output from stdout. Normally there isn't any since buildman runs + in silent mode for now. + + toolchain: Shows information about the toolchain used for the build. + + sizes: Shows image size information. + +It is possible to get the build output there also. Use the -k option for +this. In that case you will also see some output files, like: + + System.map toolchain u-boot u-boot.bin u-boot.map autoconf.mk + (also SPL versions u-boot-spl and u-boot-spl.bin if available) + + +Checking Image Sizes +==================== + +A key requirement for U-Boot is that you keep code/data size to a minimum. +Where a new feature increases this noticeably it should normally be put +behind a CONFIG flag so that boards can leave it off and keep the image +size more or less the same with each new release. + +To check the impact of your commits on image size, use -S. For example: + +$ ./tools/buildman/buildman -b us-x86 -sS +Summary of 10 commits for 1066 boards (4 threads, 1 job per thread) +01: MAKEALL: add support for per architecture toolchains +02: x86: Add function to get top of usable ram + x86: (for 1/3 boards) text -272.0 rodata +41.0 +03: x86: Add basic cache operations +04: x86: Permit bootstage and timer data to be used prior to relocation + x86: (for 1/3 boards) data +16.0 +05: x86: Add an __end symbol to signal the end of the U-Boot binary + x86: (for 1/3 boards) text +76.0 +06: x86: Rearrange the output input to remove BSS + x86: (for 1/3 boards) bss -2140.0 +07: x86: Support relocation of FDT on start-up + x86: + coreboot-x86 +08: x86: Add error checking to x86 relocation code +09: x86: Adjust link device tree include file +10: x86: Enable CONFIG_OF_CONTROL on coreboot + + +You can see that image size only changed on x86, which is good because this +series is not supposed to change any other board. From commit 7 onwards the +build fails so we don't get code size numbers. The numbers are fractional +because they are an average of all boards for that architecture. The +intention is to allow you to quickly find image size problems introduced by +your commits. + +Note that the 'text' region and 'rodata' are split out. You should add the +two together to get the total read-only size (reported as the first column +in the output from binutil's 'size' utility). + +A useful option is --step which lets you skip some commits. For example +--step 2 will show the image sizes for only every 2nd commit (so it will +compare the image sizes of the 1st, 3rd, 5th... commits). You can also use +--step 0 which will compare only the first and last commits. This is useful +for an overview of how your entire series affects code size. + +You can also use -d to see a detailed size breakdown for each board.

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.
