* @(#)driver.c 1.4 - 95/08/02
|
|
*
|
|
*
|
|
* RTEMS monitor IO (device drivers) support
|
|
*
|
|
* There are 2 "driver" things the monitor knows about.
|
|
*
|
|
* 1. Regular RTEMS drivers.
|
|
* This is a table indexed by major device number and
|
|
* containing driver entry points only.
|
|
*
|
|
* 2. Driver name table.
|
|
* A separate table of names for drivers.
|
|
* The table converts driver names to a major number
|
|
* as index into the driver table and a minor number
|
|
* for an argument to driver.
|
|
*
|
|
* Drivers are displayed with 'driver' command.
|
|
* Names are displayed with 'name' command.
|
|
*
|
|
* $Id$
