From 9bd7b3b1a26adc41678ec4d4a1d97f057cdb43a7 Mon Sep 17 00:00:00 2001 From: Daniel Hellstrom Date: Tue, 20 May 2014 17:45:07 +0200 Subject: SPARC: Fatal_halt use source and exit codes The Fatal_halt handler now have two options, either halt as before or enter system error state to return to debugger or simulator. The exit-code is now also propagated to the debugger which is very useful for testing. The CPU_Fatal_halt handler was split up into two, since the only the LEON3 support the CPU power down. The LEON3 halt now uses the power-down instruction to save CPU power. This doesn't stop a potential watch-dog timer from expiring. --- c/src/lib/libbsp/sparc/leon3/configure.ac | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'c/src/lib/libbsp/sparc/leon3/configure.ac') diff --git a/c/src/lib/libbsp/sparc/leon3/configure.ac b/c/src/lib/libbsp/sparc/leon3/configure.ac index 3fe1e48024..8ace8a30fd 100644 --- a/c/src/lib/libbsp/sparc/leon3/configure.ac +++ b/c/src/lib/libbsp/sparc/leon3/configure.ac @@ -38,6 +38,11 @@ RTEMS_BSPOPTS_HELP([BSP_LEON3_SMP], [Always defined when on a LEON3 to enable the LEON3 support for determining the CPU core number in an SMP configuration.]) +RTEMS_BSPOPTS_SET([BSP_POWER_DOWN_AT_FATAL_HALT],[*],[]) +RTEMS_BSPOPTS_HELP([BSP_POWER_DOWN_AT_FATAL_HALT], +[If defined, CPU is powered down on fatal exit.
