Hello Steven, Now I started looking at compiling 2.6.24.7-rt8 for ARM, and I found another compile problem... ;-)) This one: CC arch/arm/kernel/process.o arch/arm/kernel/process.c: In function 'cpu_idle': arch/arm/kernel/process.c:175: error: implicit declaration of function 'trace_preempt_exit_idle' arch/arm/kernel/process.c:180: error: implicit declaration of function 'trace_preempt_enter_idle' These function do not appear to exist _anywhere_ in the kernel. So these calls can safely be removed, I guess. The offending patch can be found in the broken-out set under the name arm-trace-preempt-idle.patch. Attached you can find a fix for it (I expect that you will not need it) Kind Regards, Remy
This patch fixes this compile error in 2.6.24.7-rt8: CC arch/arm/kernel/process.o arch/arm/kernel/process.c: In function 'cpu_idle': arch/arm/kernel/process.c:175: error: implicit declaration of function 'trace_preempt_exit_idle' arch/arm/kernel/process.c:180: error: implicit declaration of function 'trace_preempt_enter_idle' Signed-off-by: Remy Bohmer <linux@xxxxxxxxxx> --- arch/arm/kernel/process.c | 2 -- 1 file changed, 2 deletions(-) Index: linux-2.6.24/arch/arm/kernel/process.c =================================================================== --- linux-2.6.24.orig/arch/arm/kernel/process.c 2008-05-20 22:06:33.000000000 +0200 +++ linux-2.6.24/arch/arm/kernel/process.c 2008-05-20 22:30:37.000000000 +0200 @@ -172,12 +172,10 @@ void cpu_idle(void) idle(); leds_event(led_idle_end); local_irq_disable(); - trace_preempt_exit_idle(); tick_nohz_restart_sched_tick(); __preempt_enable_no_resched(); __schedule(); preempt_disable(); - trace_preempt_enter_idle(); local_irq_enable(); } }
