Hi

Out of curiosity, did you hack confdefs.h to force this as the
scheduler in uniprocessor configurations to ensure it does
the correct things in that situation?


I hacked some things to run the tests with the new scheduler. I added also the support for the preempt mode (this makes no sense on SMP). The following tests fail:

sp02 - This is a bug in the test.  I will send a fix.
sp66 - I think there is a bug in the test.
spfatal03 - Fails due to RTEMS_SMP is defined.
tm20 - Didn't look at it since this test tinkers with internal variables.
tm27 - Ditto.

The test sp66 checks the priority ceiling protocol. The problem is that the driver task has preemption disabled:

[...]
  sleep(1);

  puts( "Calling semaphore release" );
  status = rtems_semaphore_release( Mutex_id );
  directive_failed( status, "rtems_semaphore_release" );

To make sure the priority ceiling works, we have to check that Task_1 actually runs which is impossible since Init has preempt disabled.

  puts( "*** END OF TEST 65 ***" );

  rtems_test_exit(0);
[...]
