Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.

Module Parameters
|
|
-----------------
|
|
|
|
* adm1022_temp3: short array
|
|
List of adapter,address pairs to force chips into ADM1022 mode with
|
|
second remote temperature. This does not work for original THMC50 chips.
|

|
Description
|
|
-----------
|
|
|
|
The THMC50 implements: an internal temperature sensor, support for an
|
|
external diode-type temperature sensor (compatible w/ the diode sensor inside
|
|
many processors), and a controllable fan/analog_out DAC. For the temperature
|
|
sensors, limits can be set through the appropriate Overtemperature Shutdown
|
|
register and Hysteresis register. Each value can be set and read to half-degree
|
|
accuracy. An alarm is issued (usually to a connected LM78) when the
|
|
temperature gets higher then the Overtemperature Shutdown value; it stays on
|
|
until the temperature falls below the Hysteresis value. All temperatures are in
|
|
degrees Celsius, and are guaranteed within a range of -55 to +125 degrees.
|
|
|
|
The THMC50 only updates its values each 1.5 seconds; reading it more often
|
|
will do no harm, but will return 'old' values.
|
|
|
|
The THMC50 is usually used in combination with LM78-like chips, to measure
|
|
the temperature of the processor(s).
|
|
|
|
The ADM1022 works the same as THMC50 but it is faster (5 Hz instead of
|
|
1 Hz for THMC50). It can be also put in a new mode to handle additional
|
|
remote temperature sensor. The driver use the mode set by BIOS by default.
|
|
|
|
In case the BIOS is broken and the mode is set incorrectly, you can force
|
|
the mode with additional remote temperature with adm1022_temp3 parameter.
|
|
A typical symptom of wrong setting is a fan forced to full speed.
|
|
|
|
Driver Features
|
|
---------------
|
|
|
|
The driver provides up to three temperatures:
|
|
|
|
temp1
|
|
- internal
|
|
temp2
|
|
- remote
|
|
temp3
|
|
- 2nd remote only for ADM1022
|
|
|
|
pwm1
|
|
- fan speed (0 = stop, 255 = full)
|
|
pwm1_mode
|
|
- always 0 (DC mode)
|
|
|
|
The value of 0 for pwm1 also forces FAN_OFF signal from the chip,
|
|
so it stops fans even if the value 0 into the ANALOG_OUT register does not.
|
|
|
|
The driver was tested on Compaq AP550 with two ADM1022 chips (one works
|
|
in the temp3 mode), five temperature readings and two fans.
