From b275a14463b233925d700487ff3753028f46540f Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Tue, 29 Jun 2010 00:33:15 +0000 Subject: 2010-06-28 Joel Sherrill PR 1573/cpukit * rtems/new-exceptions/cpu.h: Add a per cpu data structure which contains the information required by RTEMS for each CPU core. This encapsulates information such as thread executing, heir, idle and dispatch needed. --- cpukit/score/cpu/powerpc/rtems/new-exceptions/cpu.h | 16 ---------------- 1 file changed, 16 deletions(-) (limited to 'cpukit/score/cpu/powerpc/rtems/new-exceptions/cpu.h') diff --git a/cpukit/score/cpu/powerpc/rtems/new-exceptions/cpu.h b/cpukit/score/cpu/powerpc/rtems/new-exceptions/cpu.h index e61cebd982..d7faefa9a6 100644 --- a/cpukit/score/cpu/powerpc/rtems/new-exceptions/cpu.h +++ b/cpukit/score/cpu/powerpc/rtems/new-exceptions/cpu.h @@ -163,22 +163,6 @@ extern "C" { /* EXTERN Context_Control_fp _CPU_Null_fp_context; */ -/* - * On some CPUs, RTEMS supports a software managed interrupt stack. - * This stack is allocated by the Interrupt Manager and the switch - * is performed in _ISR_Handler.
