In some specific situations, there is subtle bugs which depends on a specific Qemu emulator version and the code it runs. For example, EDK2 on Aarch64 could work with specific versions of Qemu, EDK2 and ATF. See commitcc0823c2d"boot/edk2: bump to version edk2-stable202405" [1]. Also, some Qemu bugs made the guest OS crash. See for example commit9534b9c00"package/qemu: fix qemu 9.x issue for AArch32 Secure PL1&0" [2]. Commit0d4177598"support/testing/infra/emulator.py: add build host dir to qemu search path" added the ability for a runtime test to select host-qemu in order to use it. It is also possible for a user to use the "utils/run-tests" script on its host system providing its own version of Qemu. The Buildroot CI can also use its Qemu version included in the reference Docker image. This means the Qemu emulator for running a runtime test can be from several sources: - Buildroot Docker reference image, - Buildroot host-qemu package version, - Developer host OS qemu version. Those versions can also change in time. In order to help debugging of those subtle emulator bugs, this commit adds a recording of the actual Qemu version used to run a test.

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.
