From 5bbc204431e8b2fbec5b06e38434031ed92e1d5c Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Wed, 16 Mar 2011 16:33:04 +0000 Subject: 2011-03-16 Jennifer Averett PR 1743/cpu * Makefile.am, configure.ac, spsize/size.c: Add Simple Priority Scheduler as complement to existing Deterministic Priority Scheduler. This scheduler serves both as an example and as a lighter weight implementation for smaller systems. * spsimplesched01/.cvsignore, spsimplesched01/Makefile.am, spsimplesched01/init.c, spsimplesched01/spsimplesched01.doc, spsimplesched01/spsimplesched01.scn, spsimplesched02/.cvsignore, spsimplesched02/Makefile.am, spsimplesched02/init.c, spsimplesched02/spsimplesched02.doc, spsimplesched02/spsimplesched02.scn, spsimplesched03/.cvsignore, spsimplesched03/Makefile.am, spsimplesched03/init.c, spsimplesched03/spsimplesched03.doc, spsimplesched03/spsimplesched03.scn: New files. --- testsuites/sptests/spsimplesched02/.cvsignore | 2 + testsuites/sptests/spsimplesched02/Makefile.am | 28 ++++ testsuites/sptests/spsimplesched02/init.c | 143 +++++++++++++++++++++ .../sptests/spsimplesched02/spsimplesched02.doc | 24 ++++ .../sptests/spsimplesched02/spsimplesched02.scn | 15 +++ 5 files changed, 212 insertions(+) create mode 100644 testsuites/sptests/spsimplesched02/.cvsignore create mode 100644 testsuites/sptests/spsimplesched02/Makefile.am create mode 100644 testsuites/sptests/spsimplesched02/init.c create mode 100644 testsuites/sptests/spsimplesched02/spsimplesched02.doc create mode 100644 testsuites/sptests/spsimplesched02/spsimplesched02.scn (limited to 'testsuites/sptests/spsimplesched02') diff --git a/testsuites/sptests/spsimplesched02/.cvsignore b/testsuites/sptests/spsimplesched02/.cvsignore new file mode 100644 index 0000000000..282522db03 --- /dev/null +++ b/testsuites/sptests/spsimplesched02/.cvsignore @@ -0,0 +1,2 @@ +Makefile +Makefile.in diff --git a/testsuites/sptests/spsimplesched02/Makefile.am b/testsuites/sptests/spsimplesched02/Makefile.am new file mode 100644 index 0000000000..fad1747b9a --- /dev/null +++ b/testsuites/sptests/spsimplesched02/Makefile.am @@ -0,0 +1,28 @@ +## +## $Id$ +## + +MANAGERS = all + +rtems_tests_PROGRAMS = spsimplesched02 +spsimplesched02_SOURCES = init.c + +dist_rtems_tests_DATA = spsimplesched02.scn +dist_rtems_tests_DATA += spsimplesched02.doc + +include $(RTEMS_ROOT)/make/custom/@RTEMS_BSP@.cfg +include $(top_srcdir)/../automake/compile.am +include $(top_srcdir)/../automake/leaf.am + +spsimplesched02_LDADD = $(MANAGERS_NOT_WANTED:%=$(PROJECT_LIB)/no-%.rel) + +AM_CPPFLAGS += -I$(top_srcdir)/../support/include + +LINK_OBJS = $(spsimplesched02_OBJECTS) $(spsimplesched02_LDADD) +LINK_LIBS = $(spsimplesched02_LDLIBS) + +spsimplesched02$(EXEEXT): $(spsimplesched02_OBJECTS) $(spsimplesched02_DEPENDENCIES) + @rm -f spsimplesched02$(EXEEXT) + $(make-exe) + +include $(top_srcdir)/../automake/local.am diff --git a/testsuites/sptests/spsimplesched02/init.c b/testsuites/sptests/spsimplesched02/init.c new file mode 100644 index 0000000000..381d4ca229 --- /dev/null +++ b/testsuites/sptests/spsimplesched02/init.c @@ -0,0 +1,143 @@ +/* + * COPYRIGHT (c) 2011. + * 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.rtems.com/license/LICENSE. + * + * $Id$ + */ + +#ifdef HAVE_CONFIG_H +#include "config.h" +#endif + +#include + +/* + * Keep the names and IDs in global variables so another task can use them. + */ +rtems_id Task_id[ 3 ]; /* array of task ids */ +rtems_name Task_name[ 3 ]; /* array of task names */ +rtems_name Semaphore_name[ 2 ]; +rtems_id Semaphore_id[ 2 ]; + +rtems_task Test_task( + rtems_task_argument unused +) +{ + rtems_id tid; + uint32_t task_index; + rtems_status_code status; + + status = rtems_task_ident( RTEMS_SELF, RTEMS_SEARCH_ALL_NODES, &tid ); + task_index = task_number( tid ); + + for ( ; ; ) { + rtems_task_wake_after( RTEMS_YIELD_PROCESSOR ); + } +} + +void ObtainRelease( bool suspendIdle ) +{ + rtems_status_code status; + + if (suspendIdle) { + puts( "INIT - Suspend Idle Task"); + status = rtems_task_suspend( _Thread_Idle->Object.id ); + directive_failed( status, "rtems_task_suspend idle" ); + } + + puts( "INIT - Obtain priority ceiling semaphore - priority increases" ); + status= rtems_semaphore_obtain( Semaphore_id[1], RTEMS_DEFAULT_OPTIONS, 0 ); + directive_failed( status, "rtems_semaphore_obtain" ); + + puts( "INIT - Obtain priority ceiling semaphore - priority decreases" ); + status = rtems_semaphore_release( Semaphore_id[1] ); + directive_failed( status, "rtems_semaphore_release" ); + + if (suspendIdle) { + puts( "INIT - Resume Idle Task"); + status = rtems_task_resume( _Thread_Idle->Object.id ); + directive_failed( status, "rtems_task_resume idle" ); + } +} + +rtems_task Init( + rtems_task_argument argument +) +{ + rtems_status_code status; + + puts( "\n\n*** SIMPLE SCHEDULER 02 TEST ***" ); + + /* + * Create the semaphore.
