2025-01-24ice: remove invalid parameter of equalizerMateusz Polchlopek1-1/+0
It occurred that in the commit 70838938e89c ("ice: Implement driver functionality to dump serdes equalizer values") the invalid DRATE parameter for reading has been added. The output of the command: $ ethtool -d <ethX> returns the garbage value in the place where DRATE value should be stored. Remove mentioned parameter to prevent return of corrupted data to userspace.

2025-01-16ice: support FW Recovery ModeKonrad Knitter1-0/+1
Recovery Mode is intended to recover from a fatal failure scenario in which the device is not accessible to the host, meaning the firmware is non-responsive. The purpose of the Firmware Recovery Mode is to enable software tools to update firmware and/or device configuration so the fatal error can be resolved. Recovery Mode Firmware supports a limited set of admin commands required for NVM update. Recovery Firmware does not support hardware interrupts so a polling mode is used. The driver will expose only the minimum set of devlink commands required for the recovery of the adapter. Using an appropriate NVM image, the user can recover the adapter using the devlink flash API. Prior to 4.20 E810 Adapter Recovery Firmware supports only the update and erase of the "fw.mgmt" component. E810 Adapter Recovery Firmware doesn't support selected preservation of cards settings or identifiers. The following command can be used to recover the adapter: $ devlink dev flash <pci-address> <update-image.bin> component fw.mgmt overwrite settings overwrite identifier Newer FW versions (4.20 or newer) supports update of "fw.undi" and "fw.netlist" components. $ devlink dev flash <pci-address> <update-image.bin> Tested on Intel Corporation Ethernet Controller E810-C for SFP FW revision 3.20 and 4.30.

2025-01-14ice: add fw and port health reportersKonrad Knitter1-0/+87
Firmware generates events for global events or port specific events. Driver shall subscribe for health status events from firmware on supported FW versions >= 1.7.6. Driver shall expose those under specific health reporter, two new reporters are introduced: - FW health reporter shall represent global events (problems with the image, recovery mode); - Port health reporter shall represent port-specific events (module failure). Firmware only reports problems when those are detected, it does not store active fault list. Driver will hold only last global and last port-specific event. Driver will report all events via devlink health report, so in case of multiple events of the same source they can be reviewed using devlink autodump feature. $ devlink health pci/0000:b1:00.3: reporter fw state healthy error 0 recover 0 auto_dump true reporter port state error error 1 recover 0 last_dump_date 2024-03-17 last_dump_time 09:29:29 auto_dump true $ devlink health diagnose pci/0000:b1:00.3 reporter port Syndrome: 262 Description: Module is not present.

2025-01-13ice: Add correct PHY lane assignmentKarol Kolacinski1-0/+1
Driver always naively assumes, that for PTP purposes, PHY lane to configure is corresponding to PF ID. This is not true for some port configurations, e.g.: - 2x50G per quad, where lanes used are 0 and 2 on each quad, but PF IDs are 0 and 1 - 100G per quad on 2 quads, where lanes used are 0 and 4, but PF IDs are 0 and 1 Use correct PHY lane assignment by getting and parsing port options. This is read from the NVM by the FW and provided to the driver with the indication of active port split. Remove ice_is_muxed_topo(), which is no longer needed.

2024-12-11ice: use structures to keep track of queue context sizeJacob Keller1-2/+9
The ice Tx and Rx queue context are currently stored as arrays of bytes with defined size (ICE_RXQ_CTX_SZ and ICE_TXQ_CTX_SZ). The packed queue context is often passed to other functions as a simple u8 * pointer, which does not allow tracking the size. This makes the queue context API easy to misuse, as you can pass an arbitrary u8 array or pointer. Introduce wrapper typedefs which use a __packed structure that has the proper fixed size for the Tx and Rx context buffers. This enables the compiler to track the size of the value and ensures that passing the wrong buffer size will be detected by the compiler. The existing APIs do not benefit much from this change, however the wrapping structures will be used to simplify the arguments of new packing functions based on the recently introduced pack_fields API.

2024-07-11ice: Add support for devlink local_forwarding paramPawel Kaminski1-1/+10
Add support for driver-specific devlink local_forwarding param. Supported values are "enabled", "disabled" and "prioritized". Default configuration is set to "enabled". Add documentation in networking/devlink/ice.rst. In previous generations of Intel NICs the transmit scheduler was only limited by PCIe bandwidth when scheduling/assigning hairpin-bandwidth between VFs. Changes to E810 HW design introduced scheduler limitation, so that available hairpin-bandwidth is bound to external port speed. In order to address this limitation and enable NFV services such as "service chaining" a knob to adjust the scheduler config was created. Driver can send a configuration message to the FW over admin queue and internal FW logic will reconfigure HW to prioritize and add more BW to VF to VF traffic. An end result, for example, 10G port will no longer limit hairpin-bandwidth to 10G and much higher speeds can be achieved. Devlink local_forwarding param set to "prioritized" enables higher hairpin-bandwitdh on related PFs. Configuration is applicable only to 8x10G and 4x25G cards. Changing local_forwarding configuration will trigger CORER reset in order to take effect.

2024-04-22ice: Support 5 layer topologyRaj Victor1-0/+23
There is a performance issue when the number of VSIs are not multiple of 8. This is caused due to the max children limitation per node(8) in 9 layer topology. The BW credits are shared evenly among the children by default. Assume one node has 8 children and the other has 1. The parent of these nodes share the BW credit equally among them. Apparently this causes a problem for the first node which has 8 children. The 9th VM get more BW credits than the first 8 VMs. Example: 1) With 8 VM's: for x in 0 1 2 3 4 5 6 7; do taskset -c ${x} netperf -P0 -H 172.68.169.125 & sleep .1 ; done tx_queue_0_packets: 23283027 tx_queue_1_packets: 23292289 tx_queue_2_packets: 23276136 tx_queue_3_packets: 23279828 tx_queue_4_packets: 23279828 tx_queue_5_packets: 23279333 tx_queue_6_packets: 23277745 tx_queue_7_packets: 23279950 tx_queue_8_packets: 0 2) With 9 VM's: for x in 0 1 2 3 4 5 6 7 8; do taskset -c ${x} netperf -P0 -H 172.68.169.125 & sleep .1 ; done tx_queue_0_packets: 24163396 tx_queue_1_packets: 24164623 tx_queue_2_packets: 24163188 tx_queue_3_packets: 24163701 tx_queue_4_packets: 24163683 tx_queue_5_packets: 24164668 tx_queue_6_packets: 23327200 tx_queue_7_packets: 24163853 tx_queue_8_packets: 91101417 So on average queue 8 statistics show that 3.7 times more packets were send there than to the other queues. The FW starting with version 3.20, has increased the max number of children per node by reducing the number of layers from 9 to 5. Reflect this on driver side.

2024-04-01ice: Add switch recipe reusing featureSteven Zou1-0/+2
New E810 firmware supports the corresponding functionality, so the driver allows PFs to subscribe the same switch recipes. Then when the PF is done with a switch recipes, the PF can ask firmware to free that switch recipe. When users configure a rule to PFn into E810 switch component, if there is no existing recipe matching this rule's pattern, the driver will request firmware to allocate and return a new recipe resource for the rule by calling ice_add_sw_recipe() and ice_alloc_recipe(). If there is an existing recipe matching this rule's pattern with different key value, or this is a same second rule to PFm into switch component, the driver checks out this recipe by calling ice_find_recp(), the driver will tell firmware to share using this same recipe resource by calling ice_subscribable_recp_shared() and ice_subscribe_recipe(). When firmware detects that all subscribing PFs have freed the switch recipe, firmware will free the switch recipe so that it can be reused. This feature also fixes a problem where all switch recipes would eventually be exhausted because switch recipes could not be freed, as freeing a shared recipe could potentially break other PFs that were using it.

While converting to FIELD_PREP() and FIELD_GET(), it was noticed that some of the RSS defines had *included* the shift in their definitions. This is completely outside of normal, such that a developer could easily make a mistake and shift at the usage site (like when using FIELD_PREP()). Rename the defines and set them to the "pre-shifted values" so they match the template the driver normally uses for masks and the member bits of the mask, which also allows the driver to use FIELD_PREP correctly with these values.

2023-12-14ice: add ability to read and configure FW log dataPaul M Stillwell Jr1-0/+2
Once logging is enabled the user should read the data from the 'data' file. The data is in the form of a binary blob that can be sent to Intel for decoding. To read the data use a command like: # cat /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/data > log_data.bin If the user wants to clear the FW log data that has been stored in the driver then they can write any value to the 'data' file and that will clear the data. An example is: # echo 34 > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/data In addition to being able to read the data the user can configure how much memory is used to store FW log data.

2023-12-14ice: configure FW loggingPaul M Stillwell Jr1-0/+80
Users want the ability to debug FW issues by retrieving the FW logs from the E8xx devices. Use debugfs to allow the user to configure the log level and number of messages for FW logging. If FW logging is supported on the E8xx then the file 'fwlog' will be created under the PCI device ID for the ice driver. If the file does not exist then either the E8xx doesn't support FW logging or debugfs is not enabled on the system. One thing users want to do is control which events are reported. The user can read and write the 'fwlog/modules/<module name>' to get/set the log levels. Each module in the FW that supports logging ht as a file under 'fwlog/modules' that supports reading (to see what the current log level is) and writing (to change the log level). The format to set the log levels for a module are: # echo <log level> > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/modules/<module> The supported log levels are: * none * error * warning * normal * verbose Each level includes the messages from the previous/lower level The modules that are supported are: * general * ctrl * link * link_topo * dnl * i2c * sdp * mdio * adminq * hdma * lldp * dcbx * dcb * xlr * nvm * auth * vpd * iosf * parser * sw * scheduler * txq * rsvd * post * watchdog * task_dispatch * mng * synce * health * tsdrv * pfreg * mdlver * all The module 'all' is a special module which allows the user to read or write to all of the modules. The following example command would set the DCB module to the 'normal' log level: # echo normal > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/modules/dcb If the user wants to set the DCB, Link, and the AdminQ modules to 'verbose' then the commands are: # echo verbose > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/modules/dcb # echo verbose > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/modules/link # echo verbose > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/modules/adminq If the user wants to set all modules to the 'warning' level then the command is: # echo warning > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/modules/all If the user wants to disable logging for a module then they can set the level to 'none'. An example setting the 'watchdog' module is: # echo none > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/modules/watchdog If the user wants to see what the log level is for a specific module then the command is: # cat /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/modules/dcb This will return the log level for the DCB module. If the user wants to see the log level for all the modules then the command is: # cat /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/modules/all Writing to the module file will update the configuration, but NOT enable the configuration (that is a separate command). In addition to configuring the modules, the user can also configure the number of log messages (nr_messages) to include in a single Admin Receive Queue (ARQ) event.The range is 1-128 (1 means push every log message, 128 means push only when the max AQ command buffer is full). The suggested value is 10. To see/change the resolution the user can read/write the 'fwlog/nr_messages' file. An example changing the value to 50 is # echo 50 > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/nr_messages To see the current value of 'nr_messages' then the command is: # cat /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/nr_messages Signed-off-by: Paul M Stillwell Jr <paul.m.stillwell.jr@intel.com> Tested-by: Pucha Himasekhar Reddy <himasekharx.reddy.pucha@intel.com> (A Contingent worker at Intel) Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>

2023-08-07ice: clean up __ice_aq_get_set_rss_lut()Przemek Kitszel1-28/+25
Refactor __ice_aq_get_set_rss_lut() to improve reader experience and limit misuse scenarios (undesired LUT size for given LUT type). Allow only 3 RSS LUT type+size variants: PF LUT sized 2048, GLOBAL LUT sized 512, and VSI LUT sized 64, which were used on default flows prior to this commit. Prior to the change, code was mixing the meaning of @params->lut_size and @params->lut_type, flag assigning logic was cryptic, while long defines made everything harder to follow. Fix that by extracting some code out to separate helpers. Drop some of "shift by 0" statements that originated from Intel's internal HW documentation. Drop some redundant VSI masks (since ice_is_vsi_valid() gives "valid" for up to 0x300 VSIs). After sweeping all the defines out of struct ice_aqc_get_set_rss_lut, it fits into 7 lines. Finally apply some cleanup to the callsite (use of the new enums, tmp var for lengthy bit extraction). Note that flags for 128 and 64 sized VSI LUT are the same, and 64 is used everywhere in the code (updated to new enum here), it just happened that there was 128 in flag name. __ice_aq_get_set_rss_key() uses the same VSI valid bit, make constant common for it and __ice_aq_get_set_rss_lut().

In DCB Willing Mode (FW managed LLDP), when the link partner changes configuration which requires fewer TCs, the TCs that are no longer needed are suspended by EMP FW, removed, and never resumed. This occurs before a MIB change event is indicated to SW. The permanent suspension and removal of these TC nodes in the scheduler prevents RDMA from being able to destroy QPs associated with this TC, requiring a CORE reset to recover. A new DCBX configuration change flow is defined to allow SW driver and other SW components (RDMA) to properly adjust to the configuration changes before they are taking effect in HW. This flow includes a two-way handshake between EMP FW<->LAN SW<->RDMA SW. List of changes: - Add 'Execute Pending LLDP MIB' AQC. - Add 'Pending Event Enable' bit. - Add additional logic to ignore Pending Event Enable' request while 'LLDP MIB Chnage' event is disabled. - Add 'Execute Pending LLDP MIB' AQC sending function to FW, which is needed to take place MIB Event change.

2022-06-02ice: fix access-beyond-end in the switch codeAlexander Lobakin1-32/+26
Global `-Warray-bounds` enablement revealed some problems, one of which is the way we define and use AQC rules messages. In fact, they have a shared header, followed by the actual message, which can be of one of several different formats. So it is straightforward enough to define that header as a separate struct and then embed it into message structures as needed, but currently all the formats reside in one union coupled with the header. Then, the code allocates only the memory needed for a particular message format, leaving the union potentially incomplete. There are no actual reads or writes beyond the end of an allocated chunk, but at the same time, the whole implementation is fragile and backed by an equilibrium rather than strong type and memory checks. Define the structures the other way around: one for the common header and the rest for the actual formats with the header embedded. There are no places where several union members would be used at the same time anyway. This allows to use proper struct_size() and let the compiler know what is going to be done. Finally, unsilence `-Warray-bounds` back for ice_switch.c. Other little things worth mentioning: * &ice_sw_rule_vsi_list_query is not used anywhere, remove it. It's weird anyway to talk to hardware with purely kernel types (bitmaps); * expand the ICE_SW_RULE_*_SIZE() macros to pass a structure variable name to struct_size() to let it do strict typechecking; * rename ice_sw_rule_lkup_rx_tx::hdr to ::hdr_data to keep ::hdr for the header structure to have the same name for it constistenly everywhere; * drop the duplicate of %ICE_SW_RULE_RX_TX_NO_HDR_SIZE residing in ice_switch.h.

2022-02-09ice: Support configuring the device to Double VLAN ModeBrett Creeley1-1/+63
In order to support configuring the device in Double VLAN Mode (DVM), the DDP and FW have to support DVM. If both support DVM, the PF that downloads the package needs to update the default recipes, set the VLAN mode, and update boost TCAM entries. To support updating the default recipes in DVM, add support for updating an existing switch recipe's lkup_idx and mask. This is done by first calling the get recipe AQ (0x0292) with the desired recipe ID. Then, if that is successful update one of the lookup indices (lkup_idx) and its associated mask if the mask is valid otherwise the already existing mask will be used. The VLAN mode of the device has to be configured while the global configuration lock is held while downloading the DDP, specifically after the DDP has been downloaded. If supported, the device will default to DVM.

2022-02-09ice: Adjust naming for inner VLAN operationsBrett Creeley1-93/+98
Current operations act on inner VLAN fields. To support double VLAN, outer VLAN operations and functions will be implemented. Add the "inner" naming to existing VLAN operations to distinguish them from the upcoming outer values and functions. Some spacing adjustments are made to align values. Note that the inner is not talking about a tunneled VLAN, but the second VLAN in the packet. For SVM the driver uses inner or single VLAN filtering and offloads and in Double VLAN Mode the driver uses the inner filtering and offloads for SR-IOV VFs in port VLANs in order to support offloading the guest VLAN while a port VLAN is configured.

2021-12-15ice: support immediate firmware activation via devlink reloadJacob Keller1-0/+7
The ice hardware contains an embedded chip with firmware which can be updated using devlink flash. The firmware which runs on this chip is referred to as the Embedded Management Processor firmware (EMP firmware). Activating the new firmware image currently requires that the system be rebooted. This is not ideal as rebooting the system can cause unwanted downtime. In practical terms, activating the firmware does not always require a full system reboot. In many cases it is possible to activate the EMP firmware immediately. There are a couple of different scenarios to cover. * The EMP firmware itself can be reloaded by issuing a special update to the device called an Embedded Management Processor reset (EMP reset). This reset causes the device to reset and reload the EMP firmware. * PCI configuration changes are only reloaded after a cold PCIe reset. Unfortunately there is no generic way to trigger this for a PCIe device without a system reboot. When performing a flash update, firmware is capable of responding with some information about the specific update requirements. The driver updates the flash by programming a secondary inactive bank with the contents of the new image, and then issuing a command to request to switch the active bank starting from the next load. The response to the final command for updating the inactive NVM flash bank includes an indication of the minimum reset required to fully update the device. This can be one of the following: * A full power on is required * A cold PCIe reset is required * An EMP reset is required The response to the command to switch flash banks includes an indication of whether or not the firmware will allow an EMP reset request. For most updates, an EMP reset is sufficient to load the new EMP firmware without issues. In some cases, this reset is not sufficient because the PCI configuration space has changed. When this could cause incompatibility with the new EMP image, the firmware is capable of rejecting the EMP reset request. Add logic to ice_fw_update.c to handle the response data flash update AdminQ commands. For the reset level, issue a devlink status notification informing the user of how to complete the update with a simple suggestion like "Activate new firmware by rebooting the system". Cache the status of whether or not firmware will restrict the EMP reset for use in implementing devlink reload. Implement support for devlink reload with the "fw_activate" flag. This allows user space to request the firmware be activated immediately. For the .reload_down handler, we will issue a request for the EMP reset using the appropriate firmware AdminQ command. If we know that the firmware will not allow an EMP reset, simply exit with a suitable netlink extended ACK message indicating that the EMP reset is not available. For the .reload_up handler, simply wait until the driver has finished resetting. Logic to handle processing of an EMP reset already exists in the driver as part of its reset and rebuild flows. Implement support for the devlink reload interface with the "fw_activate" action. This allows userspace to request activation of firmware without a reboot. Note that support for indicating the required reset and EMP reset restriction is not supported on old versions of firmware. The driver can determine if the two features are supported by checking the device capabilities report. I confirmed support has existed since at least version 5.5.2 as reported by the 'fw.mgmt' version. Support to issue the EMP reset request has existed in all version of the EMP firmware for the ice hardware. Check the device capabilities report to determine whether or not the indications are reported by the running firmware. If the reset requirement indication is not supported, always assume a full power on is necessary. If the reset restriction capability is not supported, always assume the EMP reset is available. Users can verify if the EMP reset has activated the firmware by using the devlink info report to check that the 'running' firmware version has updated. For example a user might do the following: # Check current version $ devlink dev info # Update the device $ devlink dev flash pci/0000:af:00.0 file firmware.bin # Confirm stored version updated $ devlink dev info # Reload to activate new firmware $ devlink dev reload pci/0000:af:00.0 action fw_activate # Confirm running version updated $ devlink dev info Finally, this change does *not* implement basic driver-only reload support. I did look into trying to do this. However, it requires significant refactor of how the ice driver probes and loads everything. The ice driver probe and allocation flows were not designed with such a reload in mind. Refactoring the flow to support this is beyond the scope of this change.

2021-10-28ice: Add support to print error on PHY FW load failureBrett Creeley1-0/+2
Some devices have support for loading the PHY FW and in some cases this can fail. When this fails, the FW will set the corresponding bit in the link info structure. Also, the FW will send a link event if the correct link event mask bit is set. Add support for printing an error message when the PHY FW load fails during any link configuration flow and the link event flow. Since ice_check_module_power() is already doing something very similar add a new function ice_check_link_cfg_err() so any failures reported in the link info's link_cfg_err member can be printed in this one function. Also, add the new ICE_FLAG_PHY_FW_LOAD_FAILED bit to the PF's flags so we don't constantly print this error message during link polling if the value never changed.
