hi all,
 
I am porting 24KEC soc to linux new, i have see the mips-kernel impement cache strategy: invalid and write-back,
is it right?  is it implement the write-through strategy? see in include/asm-mips/r4kcache.h
 
how i can know the kernel using which cache strategy in user space, such as how can see the /proc system to know it?
 
Best,
Figo.zhang
