The provides and rprovides had been set for skipped recipes, packages are similar to them (all of them provide something), so also set it. This makes it easier to figure out the RDEPENDS issues, for example, lmsensors (lmsensors_3.5.0.bb) RRECOMMENDS lmsensors-config-fancontrol (lmsensors-config_1.0.bb), but lmsensors-config is skipped for some reasons, then if we run: $ bitbake lmsensors ERROR: Nothing RPROVIDES 'lmsensors-config-fancontrol' (but /path/to/lmsensors_3.5.0.bb RDEPENDS on or otherwise requires it) NOTE: Runtime target 'lmsensors-config-fancontrol' is unbuildable, removing... Missing or unbuildable dependency chain was: ['lmsensors-config-fancontrol'] ERROR: Required build target 'lmsensors' has no buildable providers. Missing or unbuildable dependency chain was: ['lmsensors', 'lmsensors-config-fancontrol'] We had no way to know who rprovides lmsensors-config-fancontrol, we can figure it out by bitbake/contrib/dump_cache.py after this patch.

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.
