Hi all,
The missing bitwise-not has been added to the sim, and the patches has
been rebased to current master.
A call to ofono_sim_ready_notify() is now always expected after call to
query_passwd_state.
When ofono_sim_ready_notify() is invoked, it checks that the call is
expected and if needed, retries the query_passwd_state. Otherwise it
proceeds with sim initialization.

New subject: [sim-ready-nofify-v5 PATCH 1/3] sim: add ofono_sim_ready_notify
From: Pekka Pessi <Pekka.Pessi(a)nokia.com>
The sim atom waits for ofono_sim_ready_notify() after the callback
to query_passwd_state.
Upon call to ofono_sim_ready_notify(), SIM atom either continues
initialization or rechecks if the SIM still requires a pin code.
Based on patches by Kristen Accardi and Denis Kenzior.

As you can see, we are in fact calling ofono_sim_ready_notify twice in
short succession. The only reason we're not stuck for 5 seconds the
second time around is that the xsim notification function sets ready to
TRUE. This is all pretty convoluted. I don't really like this at all.
Another case to consider is a cold boot quirked modem, PIN disabled. We
are highly likely to receive XSIM way before we even query the PIN. So
ready is false, ready_id is > 0 and we end up waiting for 5 seconds here
for no good reason.

Hi Denis,
2011/2/10 Denis Kenzior <denkenz(a)gmail.com>:
So all this logic seems to work by luck.
AFAIK that is the way you wanted it. Continue initialization after
1) pin query returns None, and
2) notify is called after that.
If notify is called when pin is not None, recheck pin.
oFono roughly does this:
pin_query:
send AT+CPIN?
if READY then set waiting_for_pin to none, and wait in
ofono_sim_ready_notify
if PIN then set waiting_for_pin to the pin, and wait in
ofono_sim_ready_notify
ofono_sim_ready_notify:
if waiting_for_pin is none proceed with initialization
otherwise go back to pin_query
Sounds about correct.
Here's a log of this running on IFX:

As you can see, we are in fact calling ofono_sim_ready_notify twice in
short succession. The only reason we're not stuck for 5 seconds the
second time around is that the xsim notification function sets ready to
TRUE.
That is the way it was designed.
Second time around driver knows SIM is ready, so it schedules a call
to ofono_sim_ready_notify() in at_wait_for_ready().
We could avoid extra AT+CPIN? if needed, e.g., at_pin_query() could
return error immediately if ready_source is set.
This is all pretty convoluted. I don't really like this at all.
It is. How would you like to clarify the code? Better naming for
functions, comments?
Another case to consider is a cold boot quirked modem, PIN disabled.
We
are highly likely to receive XSIM way before we even query the PIN. So
ready is false, ready_id is > 0 and we end up waiting for 5 seconds here
for no good reason.
The +XSIM etc. is subscribed when SIM atom is probed, so oFono ends up
waiting only if SIM probe is done after ready indication. For MBM,
there is no good way to find out the SIM readyness (apart from reading
something from the SIM). For IFX, I think we could check the state
with an AT+XSIMSTATE? request.
Did you intend if (ok && sd_ready_id == 0) here?
Otherwise I don't see how non-quirked modems ever signal sim_ready or
why you would want to start a timer if you know a notification is coming
anyway.
The at_wait_for_ready() will schedule immediately a callback (timer
with timeout of 0) if modem has not registered a ready indication
(ready_id is 0).
