/* * RTEMS monitor driver names 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 'dname' command. * * $Id: mon-dname.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() */ #include <string.h> /* strncpy() */ #define DATACOL 15 #define CONTCOL DATACOL /* continued col */ void rtems_monitor_dname_canonical( rtems_monitor_dname_t *canonical_dname, void *dname_void ) { rtems_driver_name_t *np = (rtems_driver_name_t *) dname_void; (void) strncpy(canonical_dname->name_string, np->device_name, sizeof(canonical_dname->name_string)); canonical_dname->major = np->major; canonical_dname->minor = np->minor; } void * rtems_monitor_dname_next( void *object_information, rtems_monitor_dname_t *canonical_dname, rtems_id *next_id ) { rtems_unsigned32 n = rtems_get_index(*next_id); rtems_driver_name_t *table = _IO_Driver_name_table; rtems_driver_name_t *np = 0; /* XXX should we be using _IO_Number_of_devices */ for (np = table + n ; n<_IO_Number_of_devices; n++, np++) if (np->device_name) goto done; *next_id = RTEMS_OBJECT_ID_FINAL; return 0; done: _Thread_Disable_dispatch(); /* * dummy up a fake id and name for this item */ canonical_dname->id = n; canonical_dname->name = rtems_build_name('-', '-', '-', '-'); *next_id += 1; return np; } void rtems_monitor_dname_dump_header( boolean verbose ) { printf("\ Major:Minor Name\n"); /*23456789 123456789 123456789 123456789 123456789 123456789 123456789 123456789 0 1 2 3 4 5 6 7 */ rtems_monitor_separator(); } void rtems_monitor_dname_dump( rtems_monitor_dname_t *monitor_dname, boolean verbose ) { unsigned32 length = 0; length += rtems_monitor_pad(6, length); length += rtems_monitor_dump_hex(monitor_dname->major); length += printf(":"); length += rtems_monitor_dump_hex(monitor_dname->minor); length += rtems_monitor_pad(16, length); length += printf("%.*s", (int) sizeof(monitor_dname->name_string), (char *) monitor_dname->name_string); length += printf("\n"); length = 0; }
