There is IMAGE_GEN_DEBUGFS="1" variable that enables build of additional rootfs-dbg and additional archive that contains complimentary symbols files for a given image. But the issue with this resulting directory and tarball that before use it has to be combined with original image content. It is required since all cross debugging tools like gdb, perf, and systemtap need file system that contains both target executables/libraries and their symbols. Those tools need to find executable/library first and through it debuglink note find corresponding symbols file. image-combined-dbg when added to USER_CLASSES just copies final resulting rootfs back into rootfs-dbg creating combined target and debug symbols rootfs that can be used for debugging directly.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
