The PACKAGE_ADD_METADATA can be used to define additional metadata for packages. Changes to this variable should affect the packaging sstate hash so packages are re-generated when this variable changes. This variable is added to both PKGDATA_VARS and PACKAGEVARS. It is needed in PACKAGEVARS to ensure changes invoke do_package to re-run. It is needed in PKGDATA_VARS to ensure changes are written into the pkgdata so that the hash equiv reports a change and does not skip over the package_write tasks.

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.
