Sure sounds like it.

LSI has done a number of R3K and R4K-like designs under
their MIPS architecture license which have features
that differ from the main stream of MIPS CPUs where the OS
is concerned. Cache manipulation is a case in point.
If it's not obvious to you from the cache management
code, compare the relevant sections of your CPU manual
with the MIPS32 spec (which I think is on the web somewhere
at www.mips.com) or a copy of the R4000 manual if you
can find one kicking around somewhere.
