Currently when a tag is added to the Buildroot git tree, the gitlab-ci create a pipeline with several hundred of jobs (~750) to build all defconfigs and execute the Buildroot testsuite. However, there is only a limited number of gitlab-ci runner (9 runners) and some jobs reach the timeout limit (24h) while waiting for a runner [1]. Indeed, the Buildroot project doesn't use the Gitlab's shared runners. In addition to the pipeline created when a new tag is added to the git repository, two pipelines are created each weeks to execute the Buildroot testsuite (on monday [2]) and build all defconfigs (on Thursday [3]). At some point there are too many jobs waiting in gitlab due board defconfigs builds. Indded a board defconfig requires a lot of time (~30min) compared to other jobs in order to build a toolchain and a kernel linux along with a basic rootfs. There is currently 262 defconfigs. This is even worse when several pipelines are trigged at the same time (new git tag and scheduled pipeline trigger). In order to reduce the number of long jobs, don't build board defconfigs with pipelines trigged on tag, keeping only the runtime tests and the Qemu's defconfigs.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
