Altera Agilex SoC FPGA
Altera Agilex 5 SoC FPGA

Description¶
This driver supports hardware monitoring for Altera SoC FPGA devices through the Secure Device Manager and Stratix 10 service layer.
The following sensor types are supported:
temperature
voltage
Usage Notes¶
The stratix10-svc driver registers a socfpga-hwmon platform device when hardware monitor support is enabled. Sensor channels are selected in the driver based on the service layer compatible string:
intel,stratix10-svc
intel,agilex-svc
intel,agilex5-svc
Channel mappings are fixed in the driver (not described in DT). The tables below list the SDM page/channel encodings used for each family.

Agilex 5 omits SDM temperature channel 2 (top-left corner on Agilex) because that sensor is not present in hardware. The remaining sensors keep the same channel numbers as Agilex.
