Not arch-aarch32.inc. If you want to rename that, we can > discuss it.. but to match that naming I chose 'arch-arm64.inc'. 'aarch32' is not the same as 'arm', the arch-arm.inc covers armv4..armv7a with it various includes. aarch32 is s subset of armv7a, so please don't use that to denote 32bit arms. > (arch-armv8.inc was kept, but only includes the arch-arm64.inc file since > there are no custom optimizations for 'v8' that I can find.) > > As far as the machine name goes the original Linaro version, > genericarmv8.conf and genericarmv8b.conf, don't match any of the naming > conventions that are currently used by QEMU BSPs. > > Looking at the existing machine names: > > qemuarm.conf qemumips64.conf qemumips.conf qemuppc.conf qemux86-64.conf > qemux86.conf > > Each of the suffix names used match the Linux kernel arch naming. It seems to be following the qemu architecture name, which tends to match the kernel arch name, but not always. Apart from the naming issues, aarch64 support is incomplete in meta-aarch64 since things like ILP32 are missing as well as agreement over page size options. -- _______________________________________________ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.openembedded.org/mailman/listinfo/openembedded-core
