Currently, the ia64 kernel will print up to a certain number of fpswa fault messages per tick, with ip information about where the fault came from. The user can also choose to be notified of faults via a SIGFPE signal, but the si_info field of the siginfo structure doesn't contain enough information about the fault to be useful. I'd like to fully decode the information in the isr about what type of fault occured (whether it be a software assist fault, some sort of IEEE filter fault, etc.) and print it along with the ip when faults occur. While I'm at it, I may as well the proper SIGFPE subcode into si_info in case of signal delivery is selected. Comments? David & Bjorn, do you think this would be useful enough to get into the tree? Thanks, Jesse
