Hello Kevin,
the patch itself is all right, except some formatting issues. However, I
still don't understand why it is necessary. I did run the test suite on
a non-SMP system and it worked well. Interrupts should be enabled in
void _Thread_Handler( void )
{
Thread_Control *executing;
ISR_Level level;
Per_CPU_Control *cpu_self;
/*
* Some CPUs need to tinker with the call frame or registers when the
* thread actually begins to execute for the first time. This is a
* hook point where the port gets a shot at doing whatever it requires.
*/
_Context_Initialization_at_thread_begin();
executing = _Thread_Executing;
/*
* have to put level into a register for those cpu's that use
* inline asm here
*/
level = executing->Start.isr_level;
_ISR_Set_level( level );
here through the _ISR_Set_level().
The level shall be zero. If it is non-zero, then this is an application
bug resulting in the INTERNAL_ERROR_BAD_THREAD_DISPATCH_ENVIRONMENT
fatal error. This error happens also if you call operating system
services which block with interrupts disabled.
Do you have a self-contained test case for the RTEMS test suite which
shows the problem you want to solve?
