vme user level interrupt registration problem

Guest

Hi,

I am trying to setup user level interrupts (ULI) for my vme device on
Irix 6.2. Before I decided to use ULI, the device was working, but I
was using polling instead of interrupts.

The file irix.sm system configuration file has the following line
"USE: xiovme vmeio universe usrvme ude" which sets up the VME bus.

According to the ULI man page, I added the following line to the
irix.sm file:
"VECTOR: bustype=VME module=vmeuli ipl=7 adapter=2" leaving out ctlr
and vector (since the vector is programmable).

In the driver code, I tried to register a ULI interrupt handler by
calling the function ULI_register_vme(int fd, void (*func) (void*),
void*arg, int nsemas, char *stack, int stacksize, int ipl, int *vec)

When I run the code, I get a bus error caused by calling the
ULI_register_vme function.

Any suggestions on how I can approach to figuring this problem out?
Thanks.

Sincerely,
Richard Lin
