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. --- c/src/lib/libbsp/sparc/leon3/include/bsp.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'c/src/lib/libbsp/sparc/leon3/include/bsp.h') diff --git a/c/src/lib/libbsp/sparc/leon3/include/bsp.h b/c/src/lib/libbsp/sparc/leon3/include/bsp.h index b0a17305af..18ae87f239 100644 --- a/c/src/lib/libbsp/sparc/leon3/include/bsp.h +++ b/c/src/lib/libbsp/sparc/leon3/include/bsp.h @@ -209,6 +209,10 @@ extern void BSP_shared_interrupt_unmask(int irq); */ extern void BSP_shared_interrupt_mask(int irq); +typedef enum { + LEON3_FATAL_CPU_COUNTER_INIT +} leon3_fatal_code; + #ifdef __cplusplus } #endif -- cgit v1.2.3
