Hello:
In the present implementation of exception ipc the two registers are not used but only given with 0. It seems a little bit waste. I mean in the page fault ipc the two registers include address where page fault occurs and instruction pointer which causes the page fault. Can we make exception ipc includes two registers with the next/current eip and esp? It seems not to be bad for this system call because it is a little bit strange that this exception ipc doesn't includes anything useful.
Thanks.
