While I don't assume you have a SPARC M7-compatible machine, I think chances are good you might have a T1 machine. As a bonus, a test on an UltraSPARC I or II is very welcome as well. To clarify this: The kernel code in question contains optimizations for different CPUs, namely: - UltraSPARC I - UltraSPARC III - Niagara 1 - Niagara 2 - Niagara 4 - SPARC M7 All but Niagara 2 had bugs which Michael Karcher fixed. So far, I successfully tested on UltraSPARC III and Niagara 4 as I have access to these machines. I also own a Niagara 2 machine, but there is no testing necessary as the code was not touched. I also tested on QEMU which emulates an UltraSPARC II, meaning that the UltraSPARC I code was tested (there is no UltraSPARC II code). I used a patched kernel to force Niagara 4 to use the Niagara 1 code which worked without problems. Still, it would be nice to have testing on real machines of these types: - UltraSPARC I or II - Niagara 1 - SPARC M7 Adrian -- .''`.
