To be really sure, it would be good if you could set arbitrary non-zero
limits to in1, in4, in5 etc. otherwise we can't be sure these limits
have been restored either.
Good idea. Here is the corresponding part of my adjusted
/etc/sensors3.conf file:
chip "w83627ehf-*" "w83627dhg-*" "w83667hg-*" "nct6775-*" "nct6776-*"
label in0 "Vcore"
label in2 "AVCC"
label in3 "+3.3V"
label in7 "3VSB"
label in8 "Vbat"
set in0_min 0.5 * 1.00
set in0_max 2.0 * 1.00
set in1_min 1.6 * 1.00
set in1_max 1.95 * 1.00
set in2_min 2.0 * 1.00
set in2_max 3.5 * 1.00
set in3_min 2.0 * 1.00
set in3_max 3.5 * 1.00
set in4_min 0.8 * 1.00
set in4_max 1.2 * 1.00
set in5_min 1.5 * 1.00
set in5_max 1.95 * 1.00
set in7_min 2.0 * 1.00
set in7_max 3.5 * 1.00
set in8_min 2.0 * 1.00
set in8_max 3.5 * 1.00
There are some limits for min/max values, e.g. in5_max will get reset to
2.04 if you try to use a higher value. Therefore I've set it to 0.95 to
avoid any confusion.
So, here are the results after sensors -s:
nct6776-isa-0290
Adapter: ISA adapter
Vcore: +0.96 V (min = +0.50 V, max = +2.00 V)
in1: +1.84 V (min = +1.60 V, max = +1.95 V)
AVCC: +3.34 V (min = +2.00 V, max = +3.50 V)
+3.3V: +3.34 V (min = +2.00 V, max = +3.50 V)
in4: +1.05 V (min = +0.80 V, max = +1.20 V)
in5: +1.68 V (min = +1.50 V, max = +1.95 V)
3VSB: +3.47 V (min = +2.00 V, max = +3.50 V)
Vbat: +3.31 V (min = +2.00 V, max = +3.50 V)
And after resume:
nct6776-isa-0290
Adapter: ISA adapter
Vcore: +0.96 V (min = +0.00 V, max = +1.74 V)
in1: +1.84 V (min = +0.00 V, max = +0.00 V) ALARM
AVCC: +3.34 V (min = +0.00 V, max = +0.00 V) ALARM
+3.3V: +3.34 V (min = +0.00 V, max = +0.00 V) ALARM
in4: +1.05 V (min = +0.00 V, max = +0.00 V) ALARM
in5: +1.68 V (min = +0.00 V, max = +0.00 V) ALARM
3VSB: +3.47 V (min = +2.00 V, max = +3.50 V)
Vbat: +3.31 V (min = +2.00 V, max = +3.50 V)
Apparently, in0-in5 do not get restored, only in7 and in8 do. There is
no in6 on this chip (verified by looking in /sys/class/hwmon).
I don't get it. I have double checked my code and I don't see how this
is possible. Plus Guenter's testing was successful...
Doesn't work for me either on NCT6776F. Some of the data is restored, which is
not the case if I use the "old" driver, so I must have used the correct driver.
Hi Jean,
I found the problem. The NCT6776F has the wrong bank selected when resuming.
It started working for me after adding
data->bank = 0xff;
to the beginning of the resume function. This forces the bank register to be
updated when the first chip access is done. It might make sense to do this
for all chips with bank registers.
Guenter
Confirmed. After adding that command to the beginning of the resume
function all values get properly restored.
