eth: fbnic: Add hardware monitoring support via HWMON interfaceThis patch adds support for hardware monitoring to the fbnic driver,allowing for temperature and voltage sensor data to be exposed touserspace via the HWMON interface.

eth: fbnic: Revert "eth: fbnic: Add hardware monitoring support via HWMON 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 garbagevalue.

3d12862b - eth: fbnic: Add support to dump registers

Tue, 12 Nov 2024 22:26:05 +0000

eth: fbnic: Add support to dump registersAdd support for the 'ethtool -d ' command to retrieve and printa register dump for fbnic. The dump defaults to version 1 and consistsof two parts: all the register sections that can be dumped linearly, andan RPC RAM section that is structured in an interleaved fashion andrequires special handling. For each register section, the dump alsocontains the start and end boundary information which can simplify parsing.Signed-off-by: Mohsin Bashir Link: https://patch.msgid.link/20241112222605.3303211-1-mohsin.bashr@gmail.comSigned-off-by: Paolo Abeni List of files: /linux-6.15/drivers/net/ethernet/meta/fbnic/Makefile

eth: fbnic: Add support to fetch group statsAdd support for group stats for mac. The fbnic_set_counter help preservethe default values for counters which are not touched by the driver.The 'reset' flag in 'get_eth_mac_stats' allows to choose betweenresetting the counter to recent most value or fetching the aggregatedvalues of the counter.The 'fbnic_stat_rd64' read 64b stats counters in an atomic fashion usingread-read-read approach. This allows to isolate cases where counter ismoving too fast making accuracy of the counter questionable.Command: ethtool -S eth0 --groups eth-macExample Output:eth-mac-FramesTransmittedOK: 421644eth-mac-FramesReceivedOK: 3849708eth-mac-FrameCheckSequenceErrors: 0eth-mac-AlignmentErrors: 0eth-mac-OctetsTransmittedOK: 64799060eth-mac-FramesLostDueToIntMACXmitError: 0eth-mac-OctetsReceivedOK: 5134513531eth-mac-FramesLostDueToIntMACRcvError: 0eth-mac-MulticastFramesXmittedOK: 568eth-mac-BroadcastFramesXmittedOK: 454eth-mac-MulticastFramesReceivedOK: 276106eth-mac-BroadcastFramesReceivedOK: 26119eth-mac-FrameTooLongErrors: 0Signed-off-by: Mohsin Bashir Reviewed-by: Simon Horman Signed-off-by: David S.

69684376 - eth: fbnic: Add link detection

Fri, 12 Jul 2024 15:49:58 +0000

eth: fbnic: Add link detectionAdd basic support for detecting the link and reporting it at the netdevlayer. For now we will just use the values reporeted by the firmware as thelink configuration and assume that is the current configuration of the MACand PCS.With this we start the stubbing out of the phylink interface that will beused to provide the configuration interface for ethtool in a future patchset.The phylink interface isn't an exact fit. As such we are currently workingaround several issues in this patch set that we plan to address in thefuture such as:1. Support for FEC2. Support for multiple lanes to handle 50GbaseR2 vs 50GbaseR13.

bc610777 - eth: fbnic: Allocate a netdevice and napi vectors with queues

Fri, 12 Jul 2024 15:49:43 +0000

eth: fbnic: Allocate a netdevice and napi vectors with queuesAllocate a netdev and figure out basics like how many queueswe need, MAC address, MTU bounds. Kick off a service taskto do various periodic things like health checking.The service task only runs when device is open.We have four levels of objects here: - ring - A HW ring with head / tail pointers, - triad - Two submission and one completion ring, - NAPI - NAPI, with one IRQ and any number of Rx and Tx triads, - Netdev - The ultimate container of the rings and napi vectors.The "triad" is the only less-than-usual construct. On Rx we havetwo "free buffer" submission rings, one for packet headers andone for packet data. On Tx we have separate rings for XDP Txand normal Tx. So we ended up with ring triplets in bothdirections.We keep NAPIs on a local list, even though core already maintains a list.Later on having a separate list will matter for live reconfig.We introduce the list already, the churn would not be worth it.Signed-off-by: Alexander Duyck Link: https://patch.msgid.link/172079938358.1778861.11681469974633489463.stgit@ahduyck-xeon-server.home.arpaSigned-off-by: Jakub Kicinski List of files: /linux-6.15/drivers/net/ethernet/meta/fbnic/Makefile

da3cde08 - eth: fbnic: Add FW communication mechanism

Fri, 12 Jul 2024 15:49:31 +0000

eth: fbnic: Add FW communication mechanismAdd a mechanism for sending messages to and receiving messagesfrom the FW. The FW has fairly limited functionality, so themechanism doesn't have to support high message rate.Use device mailbox registers to form two rings, one "to" andone "from" the device. The rings are just a convention betweendriver and FW, not a HW construct. We don't expect messageslarger than 4k so use page-sized buffers.Signed-off-by: Alexander Duyck Link: https://patch.msgid.link/172079937113.1778861.10669864213768701947.stgit@ahduyck-xeon-server.home.arpaSigned-off-by: Jakub Kicinski List of files: /linux-6.15/drivers/net/ethernet/meta/fbnic/Makefile
