From 24bf11eca11947d961cc9bb5f7d92dabff169e93 Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Wed, 12 Feb 2014 10:31:38 +0100 Subject: score: Add CPU counter support Add a CPU counter interface to allow access to a free-running counter. It is useful to measure short time intervals. This can be used for example to enable profiling of critical low-level functions. Add two busy wait functions rtems_counter_delay_ticks() and rtems_counter_delay_nanoseconds() implemented via the CPU counter. --- cpukit/score/cpu/i386/Makefile.am | 1 + 1 file changed, 1 insertion(+) (limited to 'cpukit/score/cpu/i386/Makefile.am') diff --git a/cpukit/score/cpu/i386/Makefile.am b/cpukit/score/cpu/i386/Makefile.am index e35a81c333..bfc45c56e6 100644 --- a/cpukit/score/cpu/i386/Makefile.am +++ b/cpukit/score/cpu/i386/Makefile.am @@ -15,6 +15,7 @@ include_rtems_score_HEADERS += rtems/score/cpusmplock.h noinst_LIBRARIES = libscorecpu.a libscorecpu_a_SOURCES = cpu.c cpu_asm.S +libscorecpu_a_SOURCES += ../no_cpu/cpucounterread.c libscorecpu_a_CPPFLAGS = $(AM_CPPFLAGS) include $(srcdir)/preinstall.am -- cgit v1.2.3
