Description
-----------
PXE1610/PXE1110 are Multi-rail/Multiphase Digital Controllers
and compliant to
- Intel VR13 DC-DC converter specifications.
- Intel SVID protocol.
Used for Vcore power regulation for Intel VR13 based microprocessors
- Servers, Workstations, and High-end desktops
PXM1310 is a Multi-rail Controller and it is compliant to
- Intel VR13 DC-DC converter specifications.
- Intel SVID protocol.
Used for DDR3/DDR4 Memory power regulation for Intel VR13 and
IMVP8 based systems
Usage Notes
-----------
This driver does not probe for PMBus devices. You will have
to instantiate devices explicitly.
Example: the following commands will load the driver for an PXE1610
at address 0x70 on I2C bus #4::
# modprobe pxe1610
# echo pxe1610 0x70 > /sys/bus/i2c/devices/i2c-4/new_device
It can also be instantiated by declaring in device tree
