Linux 7.5 To Enable Temperature / Voltage / Power Monitoring For AMD Pensando NICs

The Linux kernel already has network drivers for the AMD Pensando networking hardware while coming for Linux 7.5 is an Ionic HWMON driver to support hardware monitoring with temperature, voltage, and power monitoring for this high-end networking gear. For those using AMD Pensando networking, the new ionic-hwmon driver is queued into net-next for introduction with the Linux 7.5 kernel in the new year. This new driver reports board and ASIC sensors such as for temperature, voltage, and power that are communicated via the device firmware. These sensors are then exposed to Linux user-space via the typical HWMON sysfs interfaces. This driver was developed by AMD engineers and with Linux 7.5+ can be enabled via the SENSORS_IONIC Kconfig option. The code was merged this week to net-next where it will reside until the Linux 7.5 merge window opens up around the end of December.
