Function cpu_handle_interrupt calls cc->cpu_exec_interrupt to process pending hardware interrupts. Under the hood cpu_exec_interrupt uses cpu->exception_index to pass information to the internal function which is usually common for exception and interrupt processing. But this value is not reset after return and may be processed again by cpu_handle_exception. This does not happen due to overwriting the exception_index at the end of cpu_handle_interrupt. But this branch may also overwrite the valid exception_index in some cases. Therefore this patch: 1. resets exception_index just after the call to cpu_exec_interrupt 2. prevents overwriting the meaningful value of exception_index Backports commit 5f3bdfd4fa33255542a4b6249913d9ffb11b44f9 from qemu |
