2025-02-20eth: fbnic: Add ethtool support for IRQ coalescingMohsin Bashir
Add ethtool support to configure the IRQ coalescing behavior. Support separate timers for Rx and Tx for time based coalescing. For frame based configuration, currently we only support the Rx side. The hardware allows configuration of descriptor count instead of frame count requiring conversion between the two. We assume 2 descriptors per frame, one for the metadata and one for the data segment. When rx-frames are not configured, we set the RX descriptor count to half the ring size as a fail safe. Default configuration: ethtool -c eth0 | grep -E "rx-usecs:|tx-usecs:|rx-frames:" rx-usecs: 30 rx-frames: 0 tx-usecs: 35 IRQ rate test: With single iperf flow we monitor IRQ rate while changing the tx-usesc and rx-usecs to high and low values. ethtool -C eth0 rx-frames 8192 rx-usecs 150 tx-usecs 150 irq/sec 13k irq/sec 14k irq/sec 14k ethtool -C eth0 rx-frames 8192 rx-usecs 10 tx-usecs 10 irq/sec 27k irq/sec 28k irq/sec 28k Validating the use of extack: ethtool -C eth0 rx-frames 16384 netlink error: fbnic: rx_frames is above device max netlink error: Invalid argument Signed-off-by: Mohsin Bashir <mohsin.bashr@gmail.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Reviewed-by: Brett Creeley <brett.creeley@amd.com> Reviewed-by: Kalesh AP <kalesh-anakkur.purayil@broadcom.com> Link: https://patch.msgid.link/20250218023520.2038010-1-mohsin.bashr@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2024-12-23eth: fbnic: add IRQ reuse supportJakub Kicinski
Change our method of swapping NAPIs without disturbing existing config. This is primarily needed for "live reconfiguration" such as changing the channel count when interface is already up. Previously we were planning to use a trick of using shared interrupts. We would install a second IRQ handler for the new NAPI, and make it return IRQ_NONE until we were ready for it to take over. This works fine functionally but breaks IRQ naming. The IRQ subsystem uses the IRQ name to create the procfs entry, since both handlers used the same name the second handler wouldn't get a proc directory registered. When first one gets removed on success full ring count change it would remove its directory and we would be left with none. New approach uses a double pointer to the NAPI. The IRQ handler needs to know how to locate the NAPI to schedule. We register a single IRQ handler and give it a pointer to a pointer. We can then change what it points to without re-registering. This may have a tiny perf impact, but really really negligible. Link: https://patch.msgid.link/20241220025241.1522781-8-kuba@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

Add PCIe hardware statistics support to the fbnic driver. These stats provide insight into PCIe transaction performance and error conditions. Which includes, read/write and completion TLP counts and DWORD counts and debug counters for tag, completion credit and NP credit exhaustion The stats are exposed via debugfs and can be used to monitor PCIe performance and debug PCIe issues.

2024-11-14eth: fbnic: Add support to dump registersMohsin Bashir
Add support for the 'ethtool -d <dev>' 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.

2024-11-07eth: fbnic: Add support to write TCE TCAM entriesMohsin Bashir
Add support to redirect host-to-BMC traffic by writing MACDA entries from the RPC (RX Parser and Classifier) to TCE-TCAM. The TCE TCAM is a small L2 destination TCAM which is placed at the end of the TX path (TCE). Unlike other NICs, where BMC diversion is typically handled by firmware, for fbnic, firmware does not touch anything related to the host; hence, the host uses TCE TCAM to divert BMC traffic. Currently, we lack metadata to track where addresses have been written in the TCAM, except for the last entry written. To address this issue, we start at the opposite end of the table in each pass, so that adding or deleting entries does not affect the availability of all entries, assuming there is no significant reordering of entries.

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.
