b2b18de0ec TIMER: Use standard calibration techniques while throttling 
Part of a previous change introduced logice which used the throttling
execution rate calibrated value to determine clock calibration when
throttling is enabled.  This provides significantly worse results than the
normal self correcting calibration process.  This commit reverses that
part of the previous change.

c8ab527f4c SCP: Add event debugging support for CPU device 
Simulators which don't have detailed debugging available on their default
device (usually CPU), automatically have the event debugging options
available.  Simulators which have CPU device debugging will have to add
the SIM_DBG_EVENT, SIM_DBG_ACTIVATE and SIM_DBG_AIO_QUEUE to
their debug option list to provide this detailed debugging.

0c4bf36e1e I620: Provide optional rate limited I/O for TTY, PTR & ptp 
Default behavior is to schedule the inter character I/O based on the
TIME (PTP, PTR) and TTIME (TTY) register variables.  With default values
here I/O completes very quickly.

A user may influence I/O rate behavior to proceed at a particular character
rate per second by using:

    sim> SET CPU CPS=nnn

or equivalently:

    sim> SET CPS=nnn

The resulting I/O completion rate will be independent of host system
processor speed and/or any I/O throttling that may be in effect.  The
above commands set the deferred I/O character completion rate for
all devices that do deferred I/O (PTP, PTR and TTY).

Each deferred I/O device can have its particular character delivery rates
specified with one of these commands:

    sim> deposit PTP CPS xxx
    sim> deposit PTR CPS yyy
    sim> deposit TTY CPS zzz

A CPS register value of 0 indicates that the default cycle based delays
specified by TIME (PTP & PTR) and TTIME (TTY) registers will control
character completion rates.

   in each device.
