The 'q' option is for modes of decoding that are quicker because they
skip or omit decoding some aspects of trace data.
If supported, the 'q' option may be repeated to increase the effect.

The "d" option may be followed by a number which has the following effect:
1 Suppress logging of perf events
Suppressing perf events is useful for decreasing the size of the log.

Change the debug logging (when used with the --time option) to time filter
logged perf events, but allow that to be overridden by using "d2" instead
of plain "d".
By default that can greatly reduce the size of the log file.

While walking code towards a FUP ip, the packet state is
INTEL_PT_STATE_FUP or INTEL_PT_STATE_FUP_NO_TIP. That was mishandled
resulting in the state becoming INTEL_PT_STATE_IN_SYNC prematurely.
The result was an occasional lost EXSTOP event.
