/* * * This routine installs an interrupt vector using the basic * RTEMS mechanisms. This implementation should be suitable for * most m68k based boards. However, if the board has an unusual * interrupt controller or most somehow manipulate board specific * hardware to enable/disable, mask, prioritize, etc an interrupt * source, then this routine should be customized to support that. * * COPYRIGHT (c) 1989-1999. * On-Line Applications Research Corporation (OAR). * * The license and distribution terms for this file may be * found in the file LICENSE in this distribution or at * http://www.OARcorp.com/rtems/license.html. * * $Id: setvec.c,v 1.2 2001-09-27 12:00:24 chris Exp $ */ #include <rtems.h> #include <bsp.h> m68k_isr_entry set_vector( /* returns old vector */ rtems_isr_entry handler, /* isr routine */ rtems_vector_number vector, /* vector number */ int type /* RTEMS or RAW intr */ ) { m68k_isr_entry previous_isr; if ( type ) rtems_interrupt_catch( handler, vector, (rtems_isr_entry *) &previous_isr ); else { _CPU_ISR_install_raw_handler( vector, handler, (void *)&previous_isr ); } return previous_isr; }
