Hello, I now realized that I was wrong, and why I was wrong. I have got the idea of the fix when I was tracing the execution of FreeBSD/mips on an AMD5120 system emulated by virtualmips (on Linux!). Its CONFIG1 register shows that there are 32 tlb 'entries', but actually a genuine ADM5120 tells that there are only 16 'entries'. I hastily assumed that this emulator worked correctly, and got wrong conclusion. I will report virtualmips guys this story. Moral: be careful about emulators. They are merely feeble softwares.
