---|
| 3 | * This routine is the shared memory driver routine which |
---|
| 4 | * generates interrupts to other CPUs. |
---|
| 5 | * |
---|
| 6 | * It uses the information placed in the node status control |
---|
| 7 | * block by each node. For example, when used with the Motorola |
---|
| 8 | * MVME136 board, the MPCSR is used. |
---|
| 9 | * |
---|
| 10 | * Input parameters: |
---|
| 11 | * node - destination of this packet (0 = broadcast) |
---|
| 12 | * |
---|
| 13 | * Output parameters: NONE |
