>From looking at the source code of 5.1.0-rc3 (target/ppc/translate_init.inc.c) it seems that this is still an issue.

The mechanism used is defined by HID0[STEN]. By default (CPU reset) HID0 is set to 0x80000000 (BTW; another small bug, qemu doesn't set the hardwired MSB), hence the software-table lookup feature is *disabled*. However, the default (and immutable) 'mmu_model' for this CPU family is POWERC_MMU_SOFT_74XX which choses the soft TLB replacement scheme. To fix this: 1) the initial mmu_model for the 7450 family (includes 7441, 7445, 7451, 7455, 7457, 7447, 7448) should be: POWERPC_MMU_32B 2) when HID0[STEN] is written then the mmu_model should be changed accordingly (I'm not familiar enough with the qemu internal state to judge if any cached state would have to be updated).
