[ECOS] How to use the trace facilities

["Rob Duncan" <rob dot duncan at designmagnitude dot com>]

I'm having a bit of trouble understanding how to use the trace
facilities.  I have configured my system with CYGDBG_USE_TRACING
enabled (and I also have CYGDBG_USE_ASSERTS enabled), and I am getting
a lot of messages generated from the kernel.  For example:

TRACE: clock.cxx           [ 706] void Cyg_Alarm::initialize()
TRACE: clock.cxx           [ 285] void Cyg_Counter::add_alarm()
TRACE: clock.cxx           [ 285] void Cyg_Counter::add_alarm()
TRACE: clock.cxx           [ 706] void Cyg_Alarm::initialize()
TRACE: thread.cxx          [ 337] static void Cyg_Thread::sleep()
TRACE: mlqueue.cxx         [ 276] void
Cyg_Scheduler_Implementation::rem_thread()
TRACE: mlqueue.cxx         [ 276] void
Cyg_Scheduler_Implementation::rem_thread()
TRACE: mlqueue.cxx         [ 330] void
Cyg_Scheduler_Implementation::rem_thread()
TRACE: thread.cxx          [ 358] static void Cyg_Thread::sleep()
TRACE: mlqueue.cxx         [ 748] void
Cyg_ThreadQueue_Implementation::enqueue()
TRACE: mlqueue.cxx         [ 748] void
Cyg_ThreadQueue_Implementation::enqueue()
TRACE: mlqueue.cxx         [ 825] void
Cyg_ThreadQueue_Implementation::enqueue()
TRACE: mlqueue.cxx         [ 119] Cyg_Thread*
Cyg_Scheduler_Implementation::schedule()

What is the recommended way of turning all of these off and
restricting the tracing to the code I explicitly want enabled?

Thanks,

Rob.
