When Yoichi said

I assume s/he meant the I-cache.
Here is the official MIPS Technologies line (and we kind of ought to know):
o The 25KF D-cache is physically indexed (and of course
o The 25KF I-cache is virtually indexed and virtually tagged - the tag
includes the ASID to reduce the number of occasions on which you
have to invalidate all the lines from a particular process.
