Hi:

I have a question about whether ppc405ep CPU supports TLB( Translation Lookaside Buffer) or HAT (Hardware Address Transition) in QEMU.

I checked the source code of QEMU, it seems like when the QEMU initializes such CPU, it never initialize TLB function. Does it mean it doesn't support TLB?

The ppc4xx MMU implementation in QEMU supports TLB based address translation. See any code behind POWERPC_MMU_SOFT_4xx cases in target-ppc/mmu_helper.c.
