Introduction to SPARC configurations
Common practices on SPARC are a little different than on AMD64. Whereas AMD64 is tuned towards at least keeping the speed, the common RISC chips don't specifically do anything in that regard, and so, 64 bit is said to be somewhat more expensive (cf. http://www.osnews.com/story/5768 ). As such, the majority of binaries in common userspace installation is comprised of ELF32 binaries. Unlike x86 however, it seems one can still issue 64-bit SPARC instructions (part of the SPARCv9 instruction set) not only from ELF64 binaries, but also from ELF32. Thus there are a number of configurations defined, shown in the table below. I added x86 at the end for a comparison.
| Insn.Set Arch. | ELF type | RPM "arch" type | autoconf triple | typical hardware |
|---|---|---|---|---|
| SPARCv7 | ELF32 | sparc | sparc-linux-gnu | |
| SPARCv8 | ELF32 | sparcv8 | sparcv8-linux-gnu | LEON |
| SPARCv9/sun4u | ELF32 | sparcv9 | sparcv9-linux-gnu | Sun E250, Fujitsu SPARC64 V–VIII, Sun/Oracle/Fujitsu M series |
| SPARCv9/sun4u | ELF64 | sparc64 | sparc64-linux-gnu | Sun E250, Fujitus SPARC64 V–VIII, Sun/Oracle/Fujitsu M series |
| SPARCv9/sun4v | ELF32 | sparcv9v | sparcv9-linux-gnu + CFLAGS=-mcpu=niagara | Sun/Oracle/Fujitsu SPARC T series |
| SPARCv9/sun4v | ELF64 | sparc64v | sparc64-linux-gnu + CFLAGS=-mcpu=niagara | Sun/Oracle/Fujitsu SPARC T series |
| i686 | ELF32 | i686 | i686-linux-gnu | |
| AMD64 | ELF64 | x86_64 | x86_64-linux-gnu |
Availability
The repositories thus provide the following: sparcv9, sparc64
Supported hardware thus: All 64-bit UltraSPARC/SPARCv9 compatible silicon.

Known bugs
- an installer image is currently absent (sort of the last piece in the puzzle)
- zypper does not pick the intuitively-correct architecture at this point
