2020-05-31ice: Ignore EMODE when setting PHY configChinh T Cao1-0/+1
When setting the PHY cfg (CQ cmd 0x0601), if the firmware responds with an EMODE error, software will ignore the error as it simply means that manageability (ex: BMC) is in control of the link and that the new setting may not be applied.

2020-05-27ice: fix MAC write commandJesse Brandeburg1-6/+4
The manage MAC write command was implemented in an overly complex way that actually didn't work, as it wasn't symmetric to the manage MAC read command, and was feeding bytes out of order to the firmware. Fix the implementation by just using a simple array to represent the MAC address when it is being written via firmware command.

2020-05-22ice: check for compatibility between DDP package and firmwareVictor Raj1-1/+3
Require the Dynamic Device Personalization (DDP) file to have the same major version number and the same or older minor number than the firmware version major and minor, respectively. Check the OS and NVM package versions before downloading the package. If the OS package version is not compatible with NVM then return an appropriate error. Split the 32-byte segment name into a 28-byte segment name and a 4-byte Track-ID. Older packages will still work with this change because no package has a name that will take up more than 28 bytes; in this case the Track-ID will be 0. Note that the driver will store the segment name as 32-bytes in the ice_hw structure, in order to normalize the length of the various package name strings that it uses. Also add section ID and structure for the segment metadata section.

2020-05-21ice: report netlist version in .info_getJacob Keller1-0/+27
The flash memory for the ice hardware contains a block of information used for link management called the Netlist module. As this essentially represents another section of firmware, add its version information to the output of the driver's .info_get handler.

2020-03-21ice: discover and store size of available flashJacob Keller1-0/+2
When reading from the NVM using a flat address, it is useful to know the upper bound on the size of the flash contents. This value is not stored within the NVM. We can determine the size by performing a bisection between upper and lower bounds. It is known that the size cannot exceed 16 MB (offset of 0xFFFFFF). Use a while loop to bisect the upper and lower bounds by reading one byte at a time. On a failed read, lower the maximum bound. On a successful read, increase the lower bound. Save this as the flash_size in the ice_nvm_info structure that contains data related to the NVM. The size will be used in a future patch for implementing full NVM read via ethtool's GEEPROM command. The maximum possible size for the flash is bounded by the size limit for the NVM AdminQ commands. Add a new macro, ICE_AQC_NVM_MAX_OFFSET, which can be used to represent this upper bound.

2020-03-21ice: create function to read a section of the NVM and Shadow RAMJacob Keller1-0/+2
The NVM contents are read via firmware by using the ice_aq_read_nvm function. This function has a couple of limits: 1) The AdminQ commands can only take buffers sized up to 4Kb. Thus, any larger read must be split into multiple reads. 2) when reading from the Shadow RAM, reads must not cross sector boundaries. The sectors are also 4Kb in size. Implement the ice_read_flat_nvm function to read portions of the NVM by flat offset. That is, to read using offsets from the start of the NVM rather than from a specific module. This function will be able to read both from the NVM and from the Shadow RAM. For simplicity NVM reads will always be broken up to not cross 4Kb page boundaries, even though this is not required unless reading from the Shadow RAM. Use this new function as the implementation of ice_read_sr_word_aq. The ice_read_sr_buf_aq function is not modified here. This is because a following change will remove the only caller of that function in favor of directly using ice_read_flat_nvm. Thus, there is little benefit to changing it now only to remove it momentarily. At the same time, the ice_read_sr_aq function will also be removed.

2020-02-15ice: Handle LAN overflow event for VF queuesBrett Creeley1-0/+11
Currently we are not handling LAN overflow events. There can be cases where LAN overflow events occur on VF queues, especially with Link Flow Control (LFC) enabled on the controlling PF. In order to recover from the LAN overflow event caused by a VF we need to determine if the queue belongs to a VF and reset that VF accordingly. The struct ice_aqc_event_lan_overflow returns a copy of the GLDCB_RTCTQ register, which tells us what the queue index is in the global/device space. The global queue index needs to first be converted to a PF space queue index and then it can be used to find if a VF owns it.

2019-04-18ice: Add code for DCB initialization part 3/4Anirudh Venkataramanan1-0/+47
This patch adds a new function ice_pf_dcb_cfg (and related helpers) which applies the DCB configuration obtained from the firmware. As part of this, VSIs/netdevs are updated with traffic class information. This patch requires a bit of a refactor of existing code. 1. For a MIB change event, the associated VSI is closed and brought up again. The gap between closing and opening the VSI can cause a race condition. Fix this by grabbing the rtnl_lock prior to closing the VSI and then only free it after re-opening the VSI during a MIB change event. 2. ice_sched_query_elem is used in ice_sched.c and with this patch, in ice_dcb.c as well. However, ice_dcb.c is not built when CONFIG_DCB is unset. This results in namespace warnings (ice_sched.o: Externally defined symbols with no external references) when CONFIG_DCB is unset. To avoid this move ice_sched_query_elem from ice_sched.c to ice_common.c.

In order to force link, ice_force_phys_link_state(vsi, link_up) will first determine the current phy capabilities. If link has not changed there is nothing to do. If link has changed, previous PHY capabilities are saved and the "Enable Automatic Link Update" and "Link Establishment State Machine (LESM)" enable bits are set. Then the new PHY config is saved. The "Enable Automatic Link Update" will force the FW to execute Setup link and restart auto-negotiation.

This patch adds AVF support for the ice PF driver by implementing the following virtchnl commands: VIRTCHNL_OP_VERSION VIRTCHNL_OP_GET_VF_RESOURCES VIRTCHNL_OP_RESET_VF VIRTCHNL_OP_ADD_ETH_ADDR VIRTCHNL_OP_DEL_ETH_ADDR VIRTCHNL_OP_CONFIG_VSI_QUEUES VIRTCHNL_OP_ENABLE_QUEUES VIRTCHNL_OP_DISABLE_QUEUES VIRTCHNL_OP_ADD_ETH_ADDR VIRTCHNL_OP_DEL_ETH_ADDR VIRTCHNL_OP_CONFIG_VSI_QUEUES VIRTCHNL_OP_ENABLE_QUEUES VIRTCHNL_OP_DISABLE_QUEUES VIRTCHNL_OP_REQUEST_QUEUES VIRTCHNL_OP_CONFIG_IRQ_MAP VIRTCHNL_OP_CONFIG_RSS_KEY VIRTCHNL_OP_CONFIG_RSS_LUT VIRTCHNL_OP_GET_STATS VIRTCHNL_OP_ADD_VLAN VIRTCHNL_OP_DEL_VLAN VIRTCHNL_OP_ENABLE_VLAN_STRIPPING VIRTCHNL_OP_DISABLE_VLAN_STRIPPING Signed-off-by: Anirudh Venkataramanan <anirudh.venkataramanan@intel.com> Tested-by: Andrew Bowers <andrewx.bowers@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
2018-10-03ice: Add support for VF reset eventsAnirudh Venkataramanan1-0/+17
Post VF initialization, there are a couple of different ways in which a VF reset can be triggered. One is when the underlying PF itself goes through a reset and other is via a VFLR interrupt. ice_reset_vf introduced in this patch handles both these cases. Also introduced in this patch is a helper function ice_aq_send_msg_to_vf to send messages to VF over the mailbox queue. The PF uses this to send reset notifications to VFs.

2018-08-28ice: Enable firmware logging during device initialization.Hieu Tran1-0/+83
To enable FW logging, the "cq_en" and "uart_en" enable bits of the "fw_log" element in struct ice_hw need to set accordingly based on some user-provided parameters during driver loading. To select which FW log events to be emitted, the "cfg" elements of corresponding FW modules in the "evnts" array member of "fw_log" need to be configured.

2018-08-28ice: Refactor VSI allocation, deletion and rebuild flowAnirudh Venkataramanan1-0/+1
This patch refactors aspects of the VSI allocation, deletion and rebuild flow. Some of the more noteworthy changes are described below. 1) On reset, all switch filters applied in the hardware are lost. In the rebuild flow, only MAC and broadcast filters are being restored. Instead, use a new function ice_replay_all_fltr to restore all the filters that were previously added. To do this, remove calls to ice_remove_vsi_fltr to prevent cleaning out the internal bookkeeping structures that ice_replay_all_fltr uses to replay filters. 2) Introduce a new state bit __ICE_PREPARED_FOR_RESET to distinguish the PF that requested the reset (and consequently prepared for it) from the rest of the PFs. These other PFs will prepare for reset only when they receive an interrupt from the firmware. 3) Use new functions ice_add_vsi and ice_free_vsi to create and destroy VSIs respectively. These functions accept a handle to uniquely identify a VSI. This same handle is required to rebuild the VSI post reset. To prevent confusion, the existing ice_vsi_add was renamed to ice_vsi_init. 4) Enhance ice_vsi_setup for the upcoming SR-IOV changes and expose a new wrapper function ice_pf_vsi_setup to create PF VSIs. Rework the error handling path in ice_setup_pf_sw. 5) Introduce a new function ice_vsi_release_all to release all PF VSIs.
