The FreeBSD/arm64 work in progress currently reports "arm64" for the machine and processor type - i.e., uname -m and uname -p. It seems that the official, awkward name aarch64 is broadly used elsewhere - for example, in toolchain triples and autoconf tests. To save us grief in the future I think it is worth following suit: diff --git a/sys/arm64/include/param.h b/sys/arm64/include/param.h index 5cd0445..525a0e7 100644 --- a/sys/arm64/include/param.h +++ b/sys/arm64/include/param.h @@ -43,10 +43,10 @@ #define STACKALIGN(p) ((uint64_t)(p) & ~STACKALIGNBYTES) #ifndef MACHINE -#define MACHINE "arm64" +#define MACHINE "aarch64" #endif #ifndef MACHINE_ARCH -#define MACHINE_ARCH "arm64" +#define MACHINE_ARCH "aarch64" #endif I'm not proposing that we rename any of the source files. I believe this approach is consistent with the Debian project - they call it the "arm64" port, but report aarch64 from uname. I believe it will be much easier for us to carry around any special-case s/aarch64/arm64/ in the base system (if necessary) than trying to teach third-party software that the FreeBSD 64-bit ARM architecture is called arm64 instead of aarch64. Any objections or concerns?
