<a href="https://cfarm.tetaneutral.net/machines/list/" rel="noreferrer noreferrer" target="_blank">https://cfarm.tetaneutral.net/machines/list/</a> says GCC22 to GCC24 is<br>
mips64. The cpuinfo is below from GCC23. I can't tell if this machine<br>
has MIPS SIMD Architecture (MSA) extensions.<br>
<br>
I know the Cavium Octeon II/CN6120 should lead me to a spec sheet but<br>
I am having trouble finding the information. I think the mips64r2<br>
implies MSA but I could be mistaken.<br>
<br>
Does the Octeon II/CN6120 have MSA? If not, then what should I be<br>
looking for when reading through marketing material and technical<br>
descriptions?<br>
<br>
Thanks<br>
