It's enough to get a Java environment running, but for decent performance, you'll need to look at a JIT either via Shark (an LLVM-based JIT started by Gary Benson) or your own MIPS-specific solution.
any mips patches are in the icedtea6 repositories. I didn't track openjdk or icedtea.
If you do care about performance, or just feel like hacking asm, there also exists a Linux MIPS port of the OpenJDK template interpreter. It's mipsel, as I believe the PS2 is, although it was written to MIPS64, so there might be some instructions used that are not in MIPS III/IV. It is available at https://www.reservoir.com/ultraviolet
this is great news. debian-mips, any volunteer to bring this into icedtea6? Matthias
