Linux HWMON sensors driver for ASUS motherboards to read sensors from the embedded controller. Many ASUS motherboards do not publish all the available sensors via the Super I/O chip but the missing ones are available through the embedded controller (EC) registers. This driver implements reading those sensor data via the WMI method BREC, which is known to be present in all ASUS motherboards based on the AMD 500 series chipsets (and probably is available in other models too). The driver needs to know exact register addresses for the sensors and thus support for each motherboard has to be added explicitly. The EC registers do not provide critical values for the sensors and as such they are not published to the HWMON. Supported motherboards: * PRIME X570-PRO * Pro WS X570-ACE * ROG CROSSHAIR VIII HERO * ROG CROSSHAIR VIII DARK HERO * ROG CROSSHAIR VIII FORMULA * ROG STRIX X570-E GAMING * ROG STRIX B550-I GAMING * ROG STRIX B550-E GAMING Co-developed-by: Eugene Shalygin <eugene.shalygin@gmail.com> Signed-off-by: Eugene Shalygin <eugene.shalygin@gmail.com> Co-developed-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Denis Pauk <pauk.denis@gmail.com> Tested-by: Tor Vic <torvic9@mailbox.org> Tested-by: Oleksandr Natalenko <oleksandr@natalenko.name> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

Description:
|
|
------------
|
|
ASUS mainboards publish hardware monitoring information via Super I/O
|
|
chip and the ACPI embedded controller (EC) registers. Some of the sensors
|
|
are only available via the EC.
|
|
|
|
ASUS WMI interface provides a method (BREC) to read data from EC registers,
|
|
which is utilized by this driver to publish those sensor readings to the
|
|
HWMON system. The driver is aware of and reads the following sensors:
|
|
|
|
1. Chipset (PCH) temperature
|
|
2. CPU package temperature
|
|
3. Motherboard temperature
|
|
4. Readings from the T_Sensor header
|
|
5. VRM temperature
|
|
6. CPU_Opt fan RPM
|
|
7. Chipset fan RPM
|
|
8. Readings from the "Water flow meter" header (RPM)
|
|
9. Readings from the "Water In" and "Water Out" temperature headers
|
|
10. CPU current
