2025-01-15eth: fbnic: hwmon: Add support for reading temperature and voltage sensorsSanman Pradhan
Add support for reading temperature and voltage sensor data from firmware by implementing a new TSENE message type and response parsing. This adds message handler infrastructure to transmit sensor read requests and parse responses. The sensor data will be exposed through the driver's hwmon interface.

interface" There is a garbage value problem in fbnic_mac_get_sensor_asic(). 'fw_cmpl' is uninitialized which makes 'sensor' and '*val' to be stored garbage value.

2024-10-17eth: fbnic: Add hardware monitoring support via HWMON interfaceSanman Pradhan
This patch adds support for hardware monitoring to the fbnic driver, allowing for temperature and voltage sensor data to be exposed to userspace via the HWMON interface. The driver registers a HWMON device and provides callbacks for reading sensor data, enabling system admins to monitor the health and operating conditions of fbnic.

2024-09-04eth: fbnic: Add support to fetch group statsMohsin Bashir
Add support for group stats for mac. The fbnic_set_counter help preserve the default values for counters which are not touched by the driver. The 'reset' flag in 'get_eth_mac_stats' allows to choose between resetting the counter to recent most value or fetching the aggregated values of the counter. The 'fbnic_stat_rd64' read 64b stats counters in an atomic fashion using read-read-read approach. This allows to isolate cases where counter is moving too fast making accuracy of the counter questionable.

2024-07-15eth: fbnic: Add link detectionAlexander Duyck
Add basic support for detecting the link and reporting it at the netdev layer. For now we will just use the values reporeted by the firmware as the link configuration and assume that is the current configuration of the MAC and PCS. With this we start the stubbing out of the phylink interface that will be used to provide the configuration interface for ethtool in a future patch set. The phylink interface isn't an exact fit. As such we are currently working around several issues in this patch set that we plan to address in the future such as: 1. Support for FEC 2. Support for multiple lanes to handle 50GbaseR2 vs 50GbaseR1 3.

2024-07-15eth: fbnic: Add register init to set PCIe/Ethernet device configAlexander Duyck
As a part of enabling the device the first step is to configure the AXI and Ethernet interfaces to allow for basic traffic. This consists of configuring several registers related to the PCIe and Ethernet FIFOs as well as configuring the handlers for moving traffic between entities.
