All values written out to pkgdata are escaped (see write_if_exists() in package.bbclass). In practice there tend not to be characters that need escaping except in the scriptlets (pkg_preinst, pkg_postinst, pkg_prerm and pkg_postrm) where currently we still see the escape codes in the corresponding files within buildhistory (e.g. \n and \t) and thus also in the output of buildhistory-diff, hindering proper diffing of changes. To fix this, when we read values from pkgdata and write them out to buildhistory, we need to interpret the escape codes by doing the exact reverse of what we do in package.bbclass.

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.
