/* void Shm_Cause_interrupt( node )
|
|
*
|
|
* This routine is the shared memory driver routine which
|
|
* generates interrupts to other CPUs.
|
|
*
|
|
* It uses the information placed in the node status control
|
|
* block by each node. For example, when used with the Motorola
|
|
* MVME136 board, the MPCSR is used.
|
|
*
|
|
* Input parameters:
|
|
* node - destination of this packet (0 = broadcast)
|
|
*
|
|
* Output parameters: NONE
