1 | /* |
---|
2 | * This routine installs an interrupt vector on CPU architectures |
---|
3 | * using the Simple Vectored Interrupt Model. This is the shared |
---|
4 | * version which does nothing BSP specific. A BSP specific version |
---|
5 | * will be needed if you need to enable an interrupt source via |
---|
6 | * some register. |
---|
7 | * |
---|
8 | * INPUT PARAMETERS: |
---|
9 | * handler - interrupt handler entry point |
---|
10 | * vector - vector number |
---|
11 | * type - 0 indicates raw hardware connect |
---|
12 | * 1 indicates RTEMS interrupt connect |
---|
13 | * |
---|
14 | * OUTPUT PARAMETERS: NONE |
---|
15 | * |
---|
16 | * RETURNS: |
---|
17 | * address of previous interrupt handler |
