From 65f868cac6f7fd5c3ad02046574c19f8f4673255 Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Wed, 23 May 2018 14:17:25 +0200 Subject: Add _CPU_Counter_frequency() Add rtems_counter_frequency() API function. Use it to initialize the counter value converter via the new system initialization step (RTEMS_SYSINIT_CPU_COUNTER). This decouples the counter implementation and the counter converter. It avoids an unnecessary pull in of the 64-bit integer division from libgcc. Update #3456. --- cpukit/score/cpu/sh/include/rtems/score/cpu.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'cpukit/score/cpu/sh/include') diff --git a/cpukit/score/cpu/sh/include/rtems/score/cpu.h b/cpukit/score/cpu/sh/include/rtems/score/cpu.h index aeef5defdd..79453bc1ac 100644 --- a/cpukit/score/cpu/sh/include/rtems/score/cpu.h +++ b/cpukit/score/cpu/sh/include/rtems/score/cpu.h @@ -721,6 +721,8 @@ void _CPU_Exception_frame_print( const CPU_Exception_frame *frame ); typedef uint32_t CPU_Counter_ticks; +uint32_t _CPU_Counter_frequency( void ); + CPU_Counter_ticks _CPU_Counter_read( void ); static inline CPU_Counter_ticks _CPU_Counter_difference( -- cgit v1.2.3
