The locale-processing in cross-localedef was proven to be unsafe to run in parallel due to the way it tried to make hard links to files that could disappear before the link operation was completed. To avoid corruption of the pseudo database, and create a deterministically generated link tree, the operation of the locale generation and the hard link resolution have been split into two separate parts. A side effect of this change is that the do_package() rule for glibc-locale will be slightly smaller because some of the hard links were missed in the past, particularly if you had a lot of cpus free to perform the work. Before the patch: % du -sk locale-tree 312524 locale-tree With the patch: % du -sk locale-tree 290772 locale-tree A number of comparisons were performed such as diffing the output, cross checking the link references using tar's listing output, and comparing against the results with out a parallel build to ensure the locale-tree is correct in its final form.

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.
