Sorry for the delay. I ran my simple stress test against the patch set and
saw no issues. For the record it is by no means a thorough regression, but it
has illuminated issues in the past.
Thanks for your testing.
The test itself uses a "heartbeat" module in the SCP firmware that generates
notifications at a programmable interval. The stress test is simply generating
these heartbeats (SCP to AP notifications) while also generating protocol version
queries (AP to SCP). The notifications are sequence numbered to verify none are
lost, however SCP to AP notification support does not support SCP generating
notifications faster than the AP can process them, so the heartbeat rate must be
reasonably slow (on the order of 10s of millliseconds).
I understand your concern. I think this doesn't get int the way of what
we are doing.
My stress tests were also run in type3 and type4 concurrent scenarios.
There were two drivers using type3 to send command looply on platform.
In the firmware terminal window,
there were two channels for type4 to generate notifications from
platform at the 1ms(even shorter) interval.
I didn't find anything issues in this stress after running a couple of
hours.
@Robbie King and @Sudeep, what do you think of my test?

Other than a super minor nit in the patch 1/2, this looks good to me.
It would be good if we can get tested-by from Robbie King
