2021-02-05ice: display stored netlist versions via devlink infoJacob Keller
Add a function to read the inactive netlist bank for version information. To support this, refactor how we read the netlist version data. Instead of using the firmware AQ interface with a module ID, read from the flash as a flat NVM, using ice_read_flash_module. This change requires a slight adjustment to the offset values used, as reading from the flat NVM includes the type field (which was stripped by firmware previously). Cleanup the macro names and move them to ice_type.h. For clarity in how we calculate the offsets and so that programmers can easily map the offset value to the data sheet, use a wrapper macro to account for the offset adjustments. Use the newly added ice_get_inactive_netlist_ver function to extract the version data from the pending netlist module update. Add the stored variants of "fw.netlist", and "fw.netlist.build" to the info version map array. With this change, we now report the "fw.netlist" and "fw.netlist.build" versions into the stored section of the devlink info report. As with the main NVM module versions, if there is no pending update, we report the currently active values as stored.

2020-05-27ice: Handle critical FW error during admin queue initializationEvan Swanson
A race condition between FW and SW can occur between admin queue setup and the first command sent. A link event may occur and FW attempts to notify a non-existent queue. FW will set the critical error bit and disable the queue. When this happens retry queue setup.

2020-05-22ice: check for compatibility between DDP package and firmwareVictor Raj
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.

2019-04-18ice: Add code for DCB initialization part 2/4Anirudh Venkataramanan
This patch introduces a new top level function ice_init_dcb (and related lower level helper functions) which continues the DCB init flow. This function uses ice_get_dcb_cfg to get, parse and store the DCB configuration. Once this is done, it sets itself up to be notified by the firmware on LLDP MIB change events.

2019-02-25ice: check for a leaf node presenceVictor Raj
Check for a leaf node presence for a given VSI. This check is required before removing a VSI since VSIs can't be removed with enabled queues (with leaf nodes) from the FW scheduler tree unless its a reset.

2018-10-03ice: Add support for VF reset eventsAnirudh Venkataramanan
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: Prevent control queue operations during resetAnirudh Venkataramanan
Once reset is issued, the driver loses all control queue interfaces. Exercising control queue operations during reset is incorrect and may result in long timeouts. This patch introduces a new field 'reset_ongoing' in the hw structure. This is set to 1 by the core driver when it receives a reset interrupt. ice_sq_send_cmd checks reset_ongoing before actually issuing the control queue operation. If a reset is in progress, it returns a soft error code (ICE_ERR_RESET_PENDING) to the caller. The caller may or may not have to take any action based on this return. Once the driver knows that the reset is done, it has to set reset_ongoing back to 0. This will allow control queue operations to be posted to the hardware again. This "bail out" logic was specifically added to ice_sq_send_cmd (which is pretty low level function) so that we have one solution in one place that applies to all types of control queues.

2018-03-26ice: Configure VSIs for Tx/RxAnirudh Venkataramanan
This patch configures the VSIs to be able to send and receive packets by doing the following: 1) Initialize flexible parser to extract and include certain fields in the Rx descriptor. 2) Add Tx queues by programming the Tx queue context (implemented in ice_vsi_cfg_txqs). Note that adding the queues also enables (starts) the queues. 3) Add Rx queues by programming Rx queue context (implemented in ice_vsi_cfg_rxqs). Note that this only adds queues but doesn't start them. The rings will be started by calling ice_vsi_start_rx_rings on interface up. 4) Configure interrupts for VSI queues. 5) Implement ice_open and ice_stop.

2018-03-26ice: Add support for switch filter programmingAnirudh Venkataramanan
A VSI needs traffic directed towards it. This is done by programming filter rules on the switch (embedded vSwitch) element in the hardware, which connects the VSI to the ingress/egress port. This patch introduces data structures and functions necessary to add remove or update switch rules on the switch element. This is a pretty low level function that is generic enough to add a whole range of filters. This patch also introduces two top level functions ice_add_mac and ice_remove mac which through a series of intermediate helper functions eventually call ice_aq_sw_rules to add/delete simple MAC based filters. It's worth noting that one invocation of ice_add_mac/ice_remove_mac is capable of adding/deleting multiple MAC filters. Also worth noting is the fact that the driver maintains a list of currently active filters, so every filter addition/removal causes an update to this list. This is done for a couple of reasons: 1) If two VSIs try to add the same filters, we need to detect it and do things a little differently (i.e. use VSI lists, described below) as the same filter can't be added more than once. 2) In the event of a hardware reset we can simply walk through this list and restore the filters. VSI Lists: In a multi-VSI situation, it's possible that multiple VSIs want to add the same filter rule. For example, two VSIs that want to receive broadcast traffic would both add a filter for destination MAC ff:ff:ff:ff:ff:ff. This can become cumbersome to maintain and so this is handled using a VSI list. A VSI list is resource that can be allocated in the hardware using the ice_aq_alloc_free_res admin queue command. Simply put, a VSI list can be thought of as a subscription list containing a set of VSIs to which the packet should be forwarded, should the filter match. For example, if VSI-0 has already added a broadcast filter, and VSI-1 wants to do the same thing, the filter creation flow will detect this, allocate a VSI list and update the switch rule so that broadcast traffic will now be forwarded to the VSI list which contains VSI-0 and VSI-1.

2018-03-26ice: Start hardware initializationAnirudh Venkataramanan
This patch implements multiple pieces of the initialization flow as follows: 1) A reset is issued to ensure a clean device state, followed by initialization of admin queue interface. 2) Once the admin queue interface is up, clear the PF config and transition the device to non-PXE mode. 3) Get the NVM configuration stored in the device's non-volatile memory (NVM) using ice_init_nvm.

2018-03-26ice: Add support for control queuesAnirudh Venkataramanan
A control queue is a hardware interface which is used by the driver to interact with other subsystems (like firmware, PHY, etc.). It is implemented as a producer-consumer ring. More specifically, an "admin queue" is a type of control queue used to interact with the firmware. This patch introduces data structures and functions to initialize and teardown control/admin queues. Once the admin queue is initialized, the driver uses it to get the firmware version.
