Thanks Martin,
But I want this capability to be built into the kernel (l4 microkernel), and I would rather not use 3rd party packages. Right now Im logging in Thread::do_send. I get the trap state as such:
Trap_state *ts = (Trap_state*)_utcb_handler;
from there i get: Unsigned32 intNo = ts->err >> 3; and Unsigned32 eax = ts->eax, and so on for ebx, etc...
I am simply looking for an easy to filter out non-linux-syscalls so I only pay attention to linux syscalls. I think intNo gets changed somehow bc checking if (intNo == 80) does not log anything!
Thanks, Andrew

Hello,
I am trying to log linux syscalls from l4linux2.6 on top of l4v2. What is

all the parameters?
There are several approaches you might want to check out:
- Use IPC tracing in the kernel debugger, - Use rt_mon or its successor GRTMon to instrument l4linux code. There is a Diplomathesis about GRTMon "A Generalized Approach to Runtime Monitoring for Real-Time Systems" available from here: http://os/project/finished/finished.xml.de
I'm not sure whether grtmon is already in our remote CVS, but I don't see a reason why it could not be ...
