Fan speed control
|

-----------------
|
||||
|

The fan speed control features are limited to manual PWM mode. Automatic
|

"Smart Guardian" mode control handling is not implemented. However
|

if you want to go for "manual mode" just write 1 to pwmN_enable.
|
||||
|
||||
If you are only able to control the fan speed with very small PWM values,
|
||||
try lowering the PWM base frequency (pwm1_freq). Depending on the fan,
|
||||
it may give you a somewhat greater control range. The same frequency is
|
||||
used to drive all fan outputs, which is why pwm2_freq and pwm3_freq are
|
||||
read-only.

Implementation Details
|
||||
----------------------
|
||||
|
||||
Future driver development should bear in mind that the following registers have
|
||||
different functions on the 627EHF and the 627DHG. Some registers also have
|
||||
different power-on default values, but BIOS should already be loading
|
||||
appropriate defaults. Note that bank selection must be performed as is currently
|
||||
done in the driver for all register addresses.
|
||||
|
||||
0x49: only on DHG, selects temperature source for AUX fan, CPU fan0
|
||||
0x4a: not completely documented for the EHF and the DHG documentation assigns
|
||||
different behavior to bits 7 and 6, including extending the temperature
|
||||
input selection to SmartFan I, not just SmartFan III. Testing on the EHF
|
||||
will reveal whether they are compatible or not.
|
||||
|
||||
0x58: Chip ID: 0xa1=EHF 0xc1=DHG
|
||||
0x5e: only on DHG, has bits to enable "current mode" temperature detection and
|
||||
critical temperature protection
|
||||
0x45b: only on EHF, bit 3, vin4 alarm (EHF supports 10 inputs, only 9 on DHG)
|
||||
0x552: only on EHF, vin4
|
||||
0x558: only on EHF, vin4 high limit
|
||||
0x559: only on EHF, vin4 low limit
|
||||
0x6b: only on DHG, SYS fan critical temperature
|
||||
0x6c: only on DHG, CPU fan0 critical temperature
|
||||
0x6d: only on DHG, AUX fan critical temperature
|
||||
0x6e: only on DHG, CPU fan1 critical temperature
|
||||
|
||||
0x50-0x55 and 0x650-0x657 are marked "Test Register" for the EHF, but "Reserved
|
||||
Register" for the DHG
|
||||
|
||||
The DHG also supports PECI, where the DHG queries Intel CPU temperatures, and
|
||||
the ICH8 southbridge gets that data via PECI from the DHG, so that the
|
||||
southbridge drives the fans. And the DHG supports SST, a one-wire serial bus.
