You may find that debugging with gdbstub or the qemu monitor easier with a routine that walks page tables for loongarch_cpu_get_phys_page_debug. For kvm, the existing code is insufficient anyway, because you'd need to emulate a hardware page table walk, not use env->tlb[], which would not be populated.
This can be improved later. Reviewed-by: Richard Henderson <richard.hender...@linaro.org> r~
