The main question is if you still get the CAN bus crash (vehicle running
into issues) with that modification in active mode. Timing statistics
were not expected to change.
Nearly 2800 frames per second is quite a lot, and most is on can1 with
many frame periods at 20 ms. Yet the total processing time averages at
30-40 ms, so there is no actual CPU capacity issue for that amount of
frames.
@Derek: can you please supply these statistics for the Leaf in drive
mode as well?

Simons car sends at least 91 process data frame IDs on can1 and 84 on
can2. Worst case would be these come all in within the shortest possible
time span, that would mean the queue needs to be able to hold 175
frames. I'd add some headroom and round up to 200.
But keep in mind, if the Incoming processing actually occasionally gets
blocked for up to 60 ms -- as indicated by Simons statistics --, the
queue may need to be twice as large.

Actually we do know that, or at least have some indication, as we count
the CAN transceiver queue overruns. That info is included as "Rx
overflw" in the can status output & as "rxovr" in the logs.
Adding a filter before queueing the frame would exclude the filtered IDs
from all vehicle processing. I meant adding a filter just to exclude IDs
from the timing statistics, assuming those are the culprits, as Simon
wrote the issue only appears after enabling the timing statistics and
printing them. That's why I asked if printing might need to lock the
statistics for too long in case of such a long list.
Completely blocking ID ranges from processing by the vehicle should
normally not be necessary, unless the Incoming handler is written very
poorly.
Yet, if we add that, a mutex in the CAN RX callback must be avoided, or
would need to be non-blocking:

A mutex like that could block the CAN task, which must be avoided at all
cost. I introduced CAN callbacks for vehicles & applications that need
to react to certain frames as fast as possible, e.g. to maintain control
precedence, so cannot use the standard CAN listener mechanism (frame
queueing).
The current poller callback use is OK, if (!) the atomic type really
isn't the culprit, ie doesn't block.
So if (!) an ID filter needs to be added before queueing, it needs to be
done in a way that needs no mutex. But I don't see an issue with the
vehicle passing a fixed filter when registering with the poller/buses.
The filter doesn't need to by mutable on the fly.
