8:23 p.m.
I finally was able to start look at Huawei again. Like reported multiple
times, huawei currently works in only in the "warm start" case (ie. plug in
modem and restart ofono). This is a regression, this worked ok a month ago.
Here's currently what I have, but pin locked sims still don't work. I'll
send the patches as RFC anyway. Please test and give feedback.

New subject: [RFC PATCH v1 1/2] huawei: poll sim state
On my Huawei E1552 when I plug in the modem (ie. cold start) with PIN locked
SIM, the sim state is 255 (HUAWEI_SIM_STATE_NOT_EXISTENT). As the modem
doesn't send ^SIMST notifications, poll the sim state until it's ready.
In theory it might be possible to do this better, for example follow
^BOOT notifications or something, but it's unknown what parameter we
should check for.

locked
SIM, the sim state is 255 (HUAWEI_SIM_STATE_NOT_EXISTENT). As the modem
doesn't send ^SIMST notifications, poll the sim state until it's ready.

I thought that I read the meaning of ^BOOT somewhere, but now I can't
find it anymore :(

You need to set the timeout variable also to 0. Otherwise you have some

Also I prefer check for the timeout variables with > 0.

Now I don't like the query_sim_state name. It should sim_poll_timeout or
something similar. At least make it clear that it is timeout.
I didn't know if you talked only about about the name of structure field
or also about the function name? I only changed the structure name.

No other modem plugin has to do it this way. Why does Huawei?
I have no idea, it may very well be that doing the initialisation wrong.
But the problem at hand I have it is that huawei_post_online() makes
assumptions about sim_state:
if (data->sim_state == HUAWEI_SIM_STATE_VALID ||
data->sim_state == HUAWEI_SIM_STATE_INVALID_CS) {
data->gprs = ofono_gprs_create(modem, 0, "atmodem", data->pcui);
data->gc = ofono_gprs_context_create(modem, 0, "atmodem",
data->modem);
if (data->gprs && data->gc)
ofono_gprs_add_context(data->gprs, data->gc);
}
And currently (with my setup) data->sim_state will be
HUAWEI_SIM_STATE_INVALID_OR_LOCKED when post_online() is called and
hence gprs context is not initialised. I didn't add the sim_state checks
so I can't comment why they are needed. But this is the commit which
added them:

huawei: Fix SIM state logic
Add support for voice-only SIM cards and enable phonebook atom for
non-voice modems.
I don't have that much time to work on this, I just want to get huawei
working again. But I'll try to do something.
I'm guessing ofono_sim_inserted_notify() has something to do this. When
I did some quick tests, IIRC I was able to see HUAWEI_SIM_STATE_VALID
only after I had called ofono_sim_inserted_notify().
I think the way you are after is that we would first receive
HUAWEI_SIM_STATE_VALID (or the three other valid states) and only then
call ofono_sim_inserted_notify(). At least to me that would make sense.
I just don't know how to do that because I see only later in the
initialisation phase.
Thoughts?
