Hi All,

we are using mips32r2 so I want to know which all pages size it can support?
When I modify arch/mips/Kconfig.  it boot sucessfully on 16KB page
size. but hang/not boot crash when change page size to 8KB,32KB and 64

I don't think 8KB and 32KB work on most mips32r2 processors. You would have to check the processor manual to be sure.

In principle, one should be able to detect this at run-time, by writing a sequence of values into the PageMask register and seeing which masks 'stick'.
