Call the new cpu_transaction_failed() hook at the places where CPU generated code interacts with the memory system: io_readx() io_writex() get_page_addr_code() Any access from C code (eg via cpu_physical_memory_rw(), address_space_rw(), ld/st_*_phys()) will *not* trigger CPU exceptions via cpu_transaction_failed(). Handling for transactions failures for this kind of call should be done by using a function which returns a MemTxResult and treating the failure case appropriately in the calling code. In an ideal world we would not generate CPU exceptions for instruction fetch failures in get_page_addr_code() but instead wait until the code translation process tried a load and it failed; however that change would require too great a restructuring and redesign to attempt at this point.
