Do I Need to enable or set l2 cache in mips for linux work

[loody <miloody@xxxxxxxxx>]

Dear all:
My cpu is 24ke and are there any l2 cache configs I have to take care
of, such linux can take advantage of it.
BTW, will I can find any tool or test program for measuring the
performance of l2 cache under linux?
Appreciate your help,
miloody
