| 4 | * There are 2 "driver" things the monitor knows about. |
---|
| 5 | * |
---|
| 6 | * 1. Regular RTEMS drivers. |
---|
| 7 | * This is a table indexed by major device number and |
---|
| 8 | * containing driver entry points only. |
---|
| 9 | * |
---|
| 10 | * 2. Driver name table. |
---|
| 11 | * A separate table of names for drivers. |
---|
| 12 | * The table converts driver names to a major number |
---|
| 13 | * as index into the driver table and a minor number |
---|
| 14 | * for an argument to driver. |
---|
| 15 | * |
---|
| 16 | * Drivers are displayed with 'driver' command. |
---|
| 17 | * Names are displayed with 'name' command. |
