fbnic: Add SW shim for MDIO interface to PMD and PCS

2025-11-27T09:41:31+00:00

In order for us to support a PCS device we need to add an MDIO bus to allow
the drivers to have access to the registers for the device.  This change
adds such an interface.

The interface will consist of 2 PHY addrs, the first one consisting of a
PMD and PCS, and the second just being a PCS. There is a need for 2 PHYs
addrs due to the fact that in order to support the 50GBase-CR2 mode we will
need to access and configure the PCS vendor registers and RSFEC registers
from the second lane identical to the first.

eth: fbnic: Create ring buffer for firmware logs

2025-07-09T00:05:46+00:00

When enabled, firmware may send logs messages which are specific to the
device and not the host. Create a ring buffer to store these messages
which are read by a user through DebugFS. Buffer access is protected by
a spinlock.

eth: fbnic: Add hardware monitoring support via HWMON interface

2025-01-15T22:14:11+00:00

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.

eth: fbnic: Revert "eth: fbnic: Add hardware monitoring support via HWMON interface"

2025-01-07T20:13:04+00:00

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. Revert commit d85ebade02e8 ("eth: fbnic: Add hardware monitoring
support via HWMON interface") to avoid this problem.

2024-11-19T02:43:41+00:00

Add the usual debugfs structure:

 fbnic/
   $pci-id/
     device-fileA
     device-fileB

This patch only adds the directories, subsequent changes
will add files.

eth: fbnic: Add support to dump registers

2024-11-14T14:28:49+00:00

Add support for the 'ethtool -d ' command to retrieve and print
a register dump for fbnic. The dump defaults to version 1 and consists
of two parts: all the register sections that can be dumped linearly, and
an RPC RAM section that is structured in an interleaved fashion and
requires special handling. For each register section, the dump also
contains the start and end boundary information which can simplify parsing.

eth: fbnic: Add support to fetch group stats

2024-09-04T12:13:12+00:00

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.
