From 11b05f11d4d6d61717e345d20f492977b95ab131 Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Thu, 8 May 2014 10:11:13 +0200 Subject: score: Fix CPU context usage on SMP We must not alter the is executing indicator in _CPU_Context_Initialize() since this would cause an invalid state during a self restart. The is executing indicator must be valid at creation time since otherwise _Thread_Kill_zombies() uses an undefined value for not started threads. This could result in a system life lock. --- cpukit/score/cpu/powerpc/rtems/score/cpu.h | 16 ++++++++++++++-- 1 file changed, 14 insertions(+), 2 deletions(-) (limited to 'cpukit/score/cpu/powerpc/rtems/score/cpu.h') diff --git a/cpukit/score/cpu/powerpc/rtems/score/cpu.h b/cpukit/score/cpu/powerpc/rtems/score/cpu.h index 18a6770788..3cad329157 100644 --- a/cpukit/score/cpu/powerpc/rtems/score/cpu.h +++ b/cpukit/score/cpu/powerpc/rtems/score/cpu.h @@ -343,8 +343,20 @@ static inline ppc_context *ppc_get_context( const Context_Control *context ) ppc_get_context(_context)->gpr1 #ifdef RTEMS_SMP - #define _CPU_Context_Get_is_executing( _context ) \ - ppc_get_context(_context)->is_executing + static inline bool _CPU_Context_Get_is_executing( + const Context_Control *context + ) + { + return ppc_get_context(context)->is_executing; + } + + static inline void _CPU_Context_Set_is_executing( + Context_Control *context, + bool is_executing + ) + { + ppc_get_context(context)->is_executing = is_executing; + } #endif #endif /* ASM */ -- cgit v1.2.3
