Michael,<br>
<br>
I suggest adding a standard bool member variable to reflect if any
filter is defined, so `PollerRxCallback()` can just skip the filter
test while that is false. A mutex has some overhead, even if used
non-blocking, and a bool variable only read there will be sufficient
to signal "apply filtering" to the callback. With the simple bool
test, all vehicles that don't need filtering (i.e. most vehicles)
will have a neglectible impact from this.<br>
<br>
<br>
Regarding the overhead: the GCC atomic implementation should use the
xtensa CPU builtin atomic support (SCOMPARE1 register & S32C1I
instruction), so should be pretty fast and not use any interrupt
disabling, see:<br>
<ul>
<li><a href="https://gcc.gnu.org/wiki/Atomic" target="_blank" rel="noreferrer">https://gcc.gnu.org/wiki/Atomic</a> (xtensa atomic support since
gcc 4.4.0)<br>

(section 4.3.13)</li>
</ul>
So I still doubt the queue overflow is the real culprit.<br>
<br>
But having the filter option doesn't hurt (with my suggestion
above), and your changes to the queue processing look promising as
well.<br>
<br>
@Derek: what was your poller tracing & timing setup when you had
the bus issue on the Leaf? I still think that was something related
to your car or setup. There are currently 11 Leafs on my server
running "edge" releases including the new poller, all without
(reported) issues.<br>

<div>Maybe somebody could grab the code and check it out in the
context of specifying some filters. This will prevent those

and even from going through the poller queue. It is
non-blocking meaning that the filter is briefly inopperational

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.<br>

@Derek: can you please supply these statistics for
the Leaf in drive mode as well?<br>

<br>
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.<br>
<br>
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.<br>

<br>
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.<br>
<br>
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.<br>
<br>
Completely blocking ID ranges from processing by the
vehicle should normally not be necessary, unless the
Incoming handler is written very poorly.<br>
<br>
<br>
Yet, if we add that, a mutex in the CAN RX callback
must be avoided, or would need to be non-blocking:<br>
<br>
<blockquote type="cite">

<br>
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).<br>
<br>
The current poller callback use is OK, if (!) the
atomic type really isn't the culprit, ie doesn't
block.<br>
<br>
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.<br>

<blockquote type="cite"> OK, I've got a new idea:
CAN timing.<br>
<br>
Comparing our esp32can bit timing to the esp-idf
driver's, there seem to be some differences:<br>
<a href="https://github.com/espressif/esp-idf/blob/master/components/hal/include/hal/twai_types_deprecated.h#L75" target="_blank" rel="noreferrer">https://github.com/espressif/esp-idf/blob/master/components/hal/include/hal/twai_types_deprecated.h#L75</a><br>
<br>
Transceivers are normally tolerant to small
timing offsets. Maybe being off a little bit has
no effect under normal conditions, but it has
when the transceiver has to cope with a filled
RX queue. That could be causing the transceiver
to slide just out of sync. If the timing gets
garbled, the transceiver would signal errors in
the packets to the bus, possibly so many the
vehicle ECUs decide to raise an error condition.<br>
<br>
Is that plausible?<br>
<br>
On why the new poller could be causing this (in
combination with too slow processing by the
vehicle): as mentioned, the standard CAN
listener mechanism doesn't care about queue
overflows. The poller does.
`OvmsPollers::Queue_PollerFrame()` does a log
call when Tx/Rx tracing is enabled, that could
even block, but tracing is optional and only
meant for debugging. Not optional is the
overflow counting using an atomic uint32.<br>
<br>
The atomic types are said to be fast, but I
never checked their actual implementation on the
ESP32. Maybe they can block as well?<br>
<br>
@Simon: it would be an option to try commenting
out the overflow counting, to see if that's
causing the issue.<br>
<br>
