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.

Description
|
|
-----------
|
|
|
|
This driver implements support for JEDEC JC 42.4 compliant temperature sensors,
|
|
which are used on many DDR3 memory modules for mobile devices and servers. Some
|
|
systems use the sensor to prevent memory overheating by automatically throttling
|
|
the memory controller.
|
|
|
|
The driver auto-detects the chips listed above, but can be manually instantiated
|
|
to support other JC 42.4 compliant chips.
|
|
|
|
Example: the following will load the driver for a generic JC 42.4 compliant
|
|
temperature sensor at address 0x18 on I2C bus #1::
|
|
|
|
# modprobe jc42
|
|
# echo jc42 0x18 > /sys/bus/i2c/devices/i2c-1/new_device
|
|
|
|
A JC 42.4 compliant chip supports a single temperature sensor. Minimum, maximum,
|
|
and critical temperature can be configured. There are alarms for high, low,
|
|
and critical thresholds.
|
|
|
|
There is also an hysteresis to control the thresholds for resetting alarms.
|
|
Per JC 42.4 specification, the hysteresis threshold can be configured to 0, 1.5,
|
|
3.0, and 6.0 degrees C. Configured hysteresis values will be rounded to those
|
|
limits. The chip supports only a single register to configure the hysteresis,
|
|
which applies to all limits. This register can be written by writing into
|
|
temp1_crit_hyst. Other hysteresis attributes are read-only.
|
|
|
|
If the BIOS has configured the sensor for automatic temperature management, it
|
|
is likely that it has locked the registers, i.e., that the temperature limits
|
|
cannot be changed.
