/* * 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: mon-driver.c,v 1.2 2001-09-27 12:01:43 chris Exp $ */ #define __RTEMS_VIOLATE_KERNEL_VISIBILITY__ #include <rtems.h> #include <rtems/monitor.h> #include <stdio.h> #include <stdlib.h> /* strtoul() */ #define DATACOL 15 #define CONTCOL DATACOL /* continued col */ void rtems_monitor_driver_canonical( rtems_monitor_driver_t *canonical_driver, void *driver_void ) { rtems_driver_address_table *d = (rtems_driver_address_table *) driver_void; rtems_monitor_symbol_canonical_by_value(&canonical_driver->initialization, (void *) d->initialization); rtems_monitor_symbol_canonical_by_value(&canonical_driver->open, (void *) d->open); rtems_monitor_symbol_canonical_by_value(&canonical_driver->close, (void *) d->close); rtems_monitor_symbol_canonical_by_value(&canonical_driver->read, (void *) d->read); rtems_monitor_symbol_canonical_by_value(&canonical_driver->write, (void *) d->write); rtems_monitor_symbol_canonical_by_value(&canonical_driver->control, (void *) d->control); } void * rtems_monitor_driver_next( void *object_info, rtems_monitor_driver_t *canonical_driver, rtems_id *next_id ) { rtems_configuration_table *c = _Configuration_Table; rtems_unsigned32 n = rtems_get_index(*next_id); if (n >= c->number_of_device_drivers) goto failed; _Thread_Disable_dispatch(); /* * dummy up a fake id and name for this item */ canonical_driver->id = n; canonical_driver->name = rtems_build_name('-', '-', '-', '-'); *next_id += 1; return (void *) (c->Device_driver_table + n); failed: *next_id = RTEMS_OBJECT_ID_FINAL; return 0; } void rtems_monitor_driver_dump_header( boolean verbose ) { printf("\ Major Entry points\n"); /*23456789 123456789 123456789 123456789 123456789 123456789 123456789 123456789 0 1 2 3 4 5 6 7 */ rtems_monitor_separator(); } void rtems_monitor_driver_dump( rtems_monitor_driver_t *monitor_driver, boolean verbose ) { unsigned32 length = 0; length += printf(" %d", monitor_driver->id); length += rtems_monitor_pad(13, length); length += printf("init: "); length += rtems_monitor_symbol_dump(&monitor_driver->initialization, verbose); length += printf("; control: "); length += rtems_monitor_symbol_dump(&monitor_driver->control, verbose); length += printf("\n"); length = 0; length += rtems_monitor_pad(13, length); length += printf("open: "); length += rtems_monitor_symbol_dump(&monitor_driver->open, verbose); length += printf("; close: "); length += rtems_monitor_symbol_dump(&monitor_driver->close, verbose); length += printf("\n"); length = 0; length += rtems_monitor_pad(13, length); length += printf("read: "); length += rtems_monitor_symbol_dump(&monitor_driver->read, verbose); length += printf("; write: "); length += rtems_monitor_symbol_dump(&monitor_driver->write, verbose); length += printf("\n"); length = 0; }
