Not sure I understand.
I'll need the names and output for the pwm* and temp* files. They
_should_ be in
/sys/class/hwmon/hwmon1/device/pwm* and /sys/class/hwmon/hwmon1/device/temp*.
the command grep /sys.... does not work, I have run an ls -l and
Phil,
It wasn't "grep /sys/...", it was "grep . /sys/class/hwmon/hwmon1/device/*".
The "." is important. Your output gives me the file names, but I need names and
content, not names and permissions.
Sorry, my mistake, I haven't seen that it ist "grep . <space> /sys..."
Hope this the correct output now
/sys/class/hwmon/hwmon1/device/pwm1:252
Looks like all pwm values report the "default" pwm value.
/sys/class/hwmon/hwmon1/device/temp1_auto_channels_pwm:1
If I understand the code and the data sheet correectly, this attribute
is a bit map used to map a temperature source to one or multiple fans.
And it looks like all temperature sources are mapped to fan1, which
in turn means that effectively temp4 controls the speed of fan1 (the highest
temperature determines the fan speed), and all other fans are not mapped to
a temperature input.
What you should probably do is to find the association between tempX and pwmX
and program tempX_auto_channels_pwm such that the two map.
For example, if temp1
is the CPU1 temperature, and pwm4 (fan4) is connected to the CPU1 fan, write
0b00001000 = 0x08 into /sys/class/hwmon/hwmon1/device/temp1_auto_channels_pwm.
Similar, if temp2 is the CPU2 temperature and fan5/pwm5 controls its fan,
write 0x10 (=16) into /sys/class/hwmon/hwmon1/device/temp2_auto_channels_pwm.
You are write, temp1 and temp2 are the values for the CPU 1 and CPU 2.
The fans for the CPU
are fan7 = CPU 1 and fan8 = CPU 2
Can you explane me in detail how you create the map 0b00001000 = 0x08 ?
I think 0x08 = 0x8 = 8 is a hexadecimal value but is this 0b00001000
also a hexadecimal value, in this case both values are not equal !?
Should I write with echo -e "\x8" >
/sys/class/hwmon/hwmon1/device/temp1_auto_channels_pwm ?
IMHO I must enable (1) the n-th bit on the auto_channels_pwm value for
the n-th fan, so in my configuration the 7 and 8 bit (begin == 0)?
Thanks
Phil
