Its configuration made a table of available schedulers and set a pointer to one of the. This was heavy handed since you can only use one scheduler in an application. This configuration mechanism resulted in a scheduler pointer being passed around when you could put all scheduler configuration in an initialized structure. --- cpukit/score/src/schedulerpriority.c | 35 +++-------------------------------- 1 file changed, 3 insertions(+), 32 deletions(-) (limited to 'cpukit/score/src/schedulerpriority.c') diff --git a/cpukit/score/src/schedulerpriority.c b/cpukit/score/src/schedulerpriority.c index aa7ecee72e..93586a8a7b 100644 --- a/cpukit/score/src/schedulerpriority.c +++ b/cpukit/score/src/schedulerpriority.c @@ -2,6 +2,7 @@ * Scheduler Handler * * Copyright (C) 2010 Gedare Bloom. + * 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 @@ -29,38 +30,8 @@ volatile Priority_bit_map_Control _Priority_Major_bit_map; Priority_bit_map_Control _Priority_Bit_map[16] CPU_STRUCTURE_ALIGNMENT; -/* - * _Scheduler_priority_Initialize - * - * Initializes the scheduler for priority scheduling. - * - * Input parameters: - * the_scheduler - pointer to scheduler control - * - * Output parameters: NONE - */ - -void _Scheduler_priority_Initialize ( - Scheduler_Control *the_scheduler -) +void _Scheduler_priority_Initialize(void) { - /* the operations table is a jump table to redirect generic scheduler - * function calls to scheduler implementation specific functions.
