Previously the Producer and Consumer interfaces tracked the
Consumer and Producer respectively at the other end of the
queue that they interacted with. This was done to avoid
modifying the queue implementation, but resulted in a rougher
interface that required additional initialization steps and
prevented alternative configurations; many producers and one
consumer for example.
This commit uses the new queue policies to track this
information. The new direct policy behaves as the old producer
and consumers did. Now the producers and consumers are just
named references to the queue that they work on and a convenient
location for a notification callback when the queue is updated in
a way that is relevent to the producer or consumer.
All users of Producer and Consumer have been updated including the
stream adaptors which are in use by the echo test code and the
mcdp28x0 driver. Use of the stream adaptors has also been
simplified.

Occasionally the charge circuit on samus gets wedged and will not
charge. This change detects when the charge circuit has failed
and automatically recovers from it. It uses the BQ PROCHOT warning
to detect the failure by setting PROCHOT to trigger when the BQ
thinks input current is higher than the input current limit. When
the failure is detected, the EC disables charging and tells PD MCU
to disable CHARGE_EN, then a couple seconds later, it re-enables
charging.
This CL also adds more communication between EC and PD for the EC
to be able to set the charge state for the PD. Valid charge states
are: No charging allowed, 5V charging only, and max charging. The
EC uses this as such:
- When the EC gets AC present interrupt, it sets off a deferred
function to change charge state to max charging after some delay
to give time for the charge circuit to settle down.
- When the EC gets AC disconnect interrupt, it disables charging
briefly, enables learn mode, and then sets 5V charging allowed.
This allows for the same starting conditions in the charge circuit
for every AC attach.
- When the EC detects a wedged charge circuit, it disables charging
and waits a few seconds before re-enabling 5V only charging.
Additionally, this change moves the charging cutoff in S3/S5/G3 when
the battery is full to the EC. With the added control for the EC
to set the PD charging state, it is more convenient for the EC to
manage cutting off charging when battery is full.
BUG=chrome-os-partner:36081
BRANCH=samus
TEST=test the basics:
- connect/disconnect zinger a bunch of times
- connect and disconnect two zingers in different order
- connect two zingers and charge override between the two
test the automatic charge wedge recover:
- wedge the charge circuit by setting charger voltage under battery
voltage: "charger voltage 7000"
- wait a few seconds for the system to recover and check it is charging
with "battery" command
test full battery charge cutoff:
- added console command to change battery soc in board/samus/extpower.c:
static int cmd_battfake(int argc, char **argv)
{
char *e;
battery_soc = strtoi(argv[1], &e, 10);
batt_soc_change();
return EC_SUCCESS;
}
DECLARE_CONSOLE_COMMAND(battfake, cmd_battfake, "", "", NULL);
- in S0, tested "battfake 100" does not disable charging.
- in G3, tested "battfake 100" disables charging and "battfake 99"
re-enables charging.
- set "battfake 100" and tested transitioning to S0 enables charging and
transitioning to S5 disables charging.
- attached two chargers and used charge override to select active port.
then toggled "battfake 100" to "battfake 99" back and forth and verified
charge override port is still the same.
test third-party 12V charger:
- plug in a bunch of times and make sure we stay at 5V for 500ms and then
transition to 12V
test with no battery:
- tested five different units with no battery and just zinger. 3/5 boot,
while the other 2 don't. But, the 2 that don't boot without battery also
can't boot w/o battery when this CL is reverted, so I don't think this
change is causing the problem, I think there is an electrical limitation.
test with EVT zinger:
- EVT zingers (P2 - C2) negotiate very quickly after connection, which
can cause INA problems w/o this CL. Tested an EVT zinger with samus and
did a bunch of connections and disconnections and verified that we always
wait at 5V for 500ms and that we don't wedge the INA circuit on connect.
test backwards compatibility:
- test new PD with old EC and make sure we can charge with zinger.
(note that if the charge circuit wedges, we won't be able to unwedge it).
- test old PD with new EC and make sure we can charge with zinger.

Several modifications to samus fast charging to fix bug where
charging circuit stops charging the battery.
- Fix bug: if we have a bad temperature reading, fast charging should
ignore it.
- Change the fast charging high temperature profile to set a charging
voltage equal to the maximum of 8.3V and the current battery voltage.
- Divide the normal temperature profile into two phases, low voltage
charging and high voltage charging. Once we transition to second
phase, don't allow it to go back to phase 1 unless AC is removed.
On samus, we have to make sure we never command the BQ to a charging
voltage that is below the present battery voltage or else the INA will
lose power and we will not be able to charge the battery until AC
is disconnected.
This also changes charge_state_v2 so that the fast charging profile
override is called even when AC is disconnected to avoid jumps in
temperature as seen by the fast charging code.
Also changes the voltage threshold for transitioning from phase 1 to
phase 2 of normal temp charging so that the transition is taken a little
earlier to match the desired profile slightly better.
BUG=chrome-os-partner:35491
BRANCH=samus
TEST=Added custom console command to be able to directly control the
battery temperature that charger_profile_override() uses:
static int command_chgtemp(int argc, char **argv)

chg_temp = strtoi(argv[1], &e, 10);
if (*e)
return EC_ERROR_PARAM1;
return EC_SUCCESS;
}
DECLARE_CONSOLE_COMMAND(chgtemp, command_chgtemp,
"",
"",
NULL);
Using this command, I jumped back and forth between all three temperature
fast charging regions and made sure that (1) we never set a charging voltage
below the present battery voltage and (2) we never stop charging the battery.
I ran this test at low battery and high battery percentage and with low load
(G3) and high load (S0 with webgl aquarium).

The original algorithm is given in the TMP006 User's Guide
(SBOU107.pdf). The algorithm we previously implemented is that,
plus some additional and completely undocumented massaging of the
Tdie and Vobj registers. The original meaning of that hack is now
lost in the mists of time, thanks to our email retention policy.
This CL introduces a new algorithm variant, but at least this
time the details are in the bug report. It's essentially the same
as the User's Guide algorithm, except that we apply one-stage FIR
filters to the Tdie input and the Tobj output.
There are five new parameters: d0, d1, ds, e0, e1. Refer to
tmp006_read_object_temp_k() in ec/driver/temp_sensor/tmp006.c to
see how these new parameters are applied.
CAUTION: The tmp006 sensor algorithm is mostly math and magic
numbers. The spreadsheet attached to the bug report has six
sheets with wildly varying values for those parameters. Since the
correct parameter values haven't yet been determined for Samus,
all I can be sure of with this CL is that it seems to work and
isn't any worse than the old one.
Oh, and note that the EC's 't6cal' console command has been
disabled until/unless we add support for floating point IO. Use
ectool from the host to get and set the params instead.

There are six tmp006 object temps that need calibrating. The
index used for the calibration is for the tmp006 objects, not the
3,5,7,.. numbers reported for all temp sensors. See the current
values with tmp006cal:
localhost ~ # /tmp/ectool tmp006cal 5
algorithm: 1
params:
s0 0.000000e+00
a1 1.750000e-03
a2 -1.678000e-05
b0 -2.940000e-05
b1 -5.700000e-07
b2 4.630000e-09
c2 1.340000e+01
d0 2.000000e-01
d1 8.000000e-01
ds 1.480000e-04
e0 1.000000e-01
e1 9.000000e-01
localhost ~ #
If the s0 param is zero, this sensor is uncalibrated. The params
are entered in the order in which they're displayed You can
change any or all of the parameters. Skip the ones you don't want
to update by specifying '-' for its position. (Note: throw in an
extra '--' first so that ectool doesn't think that negative
numbers are command options).
For example, to change s0 and b0:
localhost ~ # ectool -- tmp006cal 5 1.0 - - -3.0
localhost ~ #
localhost ~ # ectool tmp006cal 5
algorithm: 1
params:
s0 1.000000e+00
a1 1.750000e-03
a2 -1.678000e-05
b0 -3.000000e+00
b1 -5.700000e-07
b2 4.630000e-09
c2 1.340000e+01

Design Goals:
1. Every time the AP boots, the same default sensor settings are configured.
2. If the AP goes to suspend (S3) and wakes back up (S0),
then the AP sensor settings will be restored.
3. In S3 and in S5, only sample specific sensors that are needed.
