[Adeos-main] ppc64 pipeline problem

[Reynolds, Terry \(Contractor-SIMTECH\)]

Hi All,
 
I've corrected the syscall portion of the pipeline, and have a new, but 
similar, problem.  The 
ADEOS_SYSCALL_PROLOGUE event (event 4 on this system) is now branching to 
__adeos_enter_syscall
function, which calls adeos_handle_event.  This eventually returns to the 
kernel, marked as to be handled via the linux
syscall code.  This starts a long loop of event 4's, which are apparently not 
being processed
correctly.
 
I get this behavior when trying to load the rtai_nucleus module, or run the 
latency example.
 
What syscall event does this adeos event 4 correspond to?   What generated it?  
 
FYI, when I modify entry.S to call a .do_show_syscall for this event what I get 
is:
 
syscall 3221225472 ( f7db7000, 1000, 1000, f7db8000, fe92d50, 100000000200f932) 
regs=c00000000065aefc
current=c00000007983b1c0 cpu=0 
 
Which is :
syscall gpr0 ( r3, r4, r5, r6, r7, r8) r9(ptr to regs) current_task cpu#
 
Thanks,
 
Terry
