Kernel driver aquacomputer-d5next
|
||||
=================================
|
||||
|
||||
Supported devices:
|
||||
|
||||
* Aquacomputer D5 Next watercooling pump
|
||||
|
||||
Author: Aleksa Savic
|
||||
|
||||
Description
|
||||
-----------
|
||||
|
||||
This driver exposes hardware sensors of the Aquacomputer D5 Next watercooling
|
||||
pump, which communicates through a proprietary USB HID protocol.
|
||||
|
||||
Available sensors are pump and fan speed, power, voltage and current, as
|
||||
well as coolant temperature. Also available through debugfs are the serial
|
||||
number, firmware version and power-on count.
|
||||
|
||||
Attaching a fan is optional and allows it to be controlled using temperature
|
||||
curves directly from the pump. If it's not connected, the fan-related sensors
|
||||
will report zeroes.
|
||||
|
||||
The pump can be configured either through software or via its physical
|
||||
interface. Configuring the pump through this driver is not implemented, as it
|
||||
seems to require sending it a complete configuration. That includes addressable
|
||||
RGB LEDs, for which there is no standard sysfs interface. Thus, that task is
|
||||
better suited for userspace tools.
|
||||
|
||||
Usage notes
|
||||
-----------
|
||||
|
||||
The pump communicates via HID reports. The driver is loaded automatically by
|
||||
the kernel and supports hotswapping.

Kernel driver sbrmi
|
||||
===================
|
||||
|
||||
Supported hardware:
|
||||
|
||||
* Sideband Remote Management Interface (SB-RMI) compliant AMD SoC
|
||||
device connected to the BMC via the APML.
|
||||
|
||||
Prefix: 'sbrmi'
|
||||
|
||||
Addresses scanned: This driver doesn't support address scanning.
|
||||
|
||||
To instantiate this driver on an AMD CPU with SB-RMI
|
||||
support, the i2c bus number would be the bus connected from the board
|
||||
management controller (BMC) to the CPU.
|
||||
The SMBus address is really 7 bits. Some vendors and the SMBus
|
||||
specification show the address as 8 bits, left justified with the R/W
|
||||
bit as a write (0) making bit 0. Some vendors use only the 7 bits
|
||||
to describe the address.
|
||||
As mentioned in AMD's APML specification, The SB-RMI address is
|
||||
normally 78h(0111 100W) or 3Ch(011 1100) for socket 0 and 70h(0111 000W)
|
||||
or 38h(011 1000) for socket 1, but it could vary based on hardware
|
||||
address select pins.
|
||||
|
||||
Datasheet: The SB-RMI interface and protocol along with the Advanced
|
||||
Platform Management Link (APML) Specification is available
|
||||

Description
|
||||
-----------
|
||||
|
||||
The APML provides a way to communicate with the SB Remote Management interface
|
||||
(SB-RMI) module from the external SMBus master that can be used to report socket
|
||||
power on AMD platforms using mailbox command and resembles a typical 8-pin remote
|
||||
power sensor's I2C interface to BMC.
|
||||
|
||||
This driver implements current power with power cap and power cap max.
|
||||
|
||||
sysfs-Interface
|
||||
---------------
|
||||
Power sensors can be queried and set via the standard ``hwmon`` interface
|
||||
on ``sysfs``, under the directory ``/sys/class/hwmon/hwmonX`` for some value
|
||||
of ``X`` (search for the ``X`` such that ``/sys/class/hwmon/hwmonX/name`` has
|
||||
content ``sbrmi``)
