[Qemu-devel] How can I distinguish TLB miss in MMU simulation?

[Zhi-zhou Zhang]

Hi All,

I'm adding a new target to qemu, now, I'm writing mmu simulation, but
it make me confused.

When TLB miss occurred, I can't seperate DTLB miss from ITLB miss.

I implemented it like this from target-xtensa:

if (rw & 2)
   HANDLE DTLB MISS
else
   HANDLE ITLB MISS

But it didn't work. May I have some suggestions?
