From 4adaed7328e39eac4fe1879cba61919e74965cc8 Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Tue, 27 Jul 2021 11:08:54 +0200 Subject: score: Remove processor event broadcast/receive Remove _CPU_SMP_Processor_event_broadcast() and _CPU_SMP_Processor_event_receive(). These functions are hard to use since they are subject to the lost wake up problem. --- cpukit/score/cpu/no_cpu/include/rtems/score/cpu.h | 29 ----------------------- 1 file changed, 29 deletions(-) (limited to 'cpukit/score/cpu/no_cpu/include') diff --git a/cpukit/score/cpu/no_cpu/include/rtems/score/cpu.h b/cpukit/score/cpu/no_cpu/include/rtems/score/cpu.h index 120b51b633..c4cb512e20 100644 --- a/cpukit/score/cpu/no_cpu/include/rtems/score/cpu.h +++ b/cpukit/score/cpu/no_cpu/include/rtems/score/cpu.h @@ -1347,35 +1347,6 @@ static inline CPU_Counter_ticks _CPU_Counter_difference( */ void _CPU_SMP_Send_interrupt( uint32_t target_processor_index ); - /** - * @brief Broadcasts a processor event. - * - * Some architectures provide a low-level synchronization primitive for - * processors in a multi-processor environment.
