The following set of NPC registers allow the driver to configure NPC to generate different key value schemes to compare against packet payload in MCAM search. NPC_AF_INTF(0..1)_KEX_CFG NPC_AF_KEX_LDATA(0..1)_FLAGS_CFG NPC_AF_INTF(0..1)_LID(0..7)_LT(0..15)_LD(0..1)_CFG NPC_AF_INTF(0..1)_LDATA(0..1)_FLAGS(0..15)_CFG Currently, the AF driver populates these registers to configure the default values to address the most common use cases such as key generation for channel number + DMAC. The secure firmware stores different configuration value of these registers to enable different NPC use case along with the name for the lookup. Patch loads profile binary from secure firmware over the exiting CGX mailbox interface and apply the profile. AF driver shall fall back to the default configuration in case of any errors. The AF consumer driver can know the selected profile on response to NPC_GET_KEX_CFG mailbox by introducing mkex_pfl_name in the struct npc_get_kex_cfg_rsp. Signed-off-by:

NIX_AF_LSO_FORMAT(0..31)_FIELD(0..7) register enables an SW defined means to define LSO packet modification formats. 0..31 works as an index to choose the algorithm, On success, the mailbox returns the index to the client of chosen LSO algorithm selection. This index will be used in configuring the transmit descriptors. Add mailbox interface to dynamically reserve and configure LSO format. This commit also fixes 'sizem1' for NIX_LSOALG_TCP_FLAGS to '1' i.e 2 Bytes. Signed-off-by:

NIX_AF_MARK_FORMAT(0..127)_CTL register enables an SW defined means to mark/insert various data in the packet based on final packet color from traffic shaping HW. 0..127 works as an index to choose the algorithm. On success, the mailbox returns the index to the client. Add NIX_MARK_FORMAT_CFG mailbox which reserves mark format based on tuple (offset, y_mask, y_val, r_mask, r_val) If the tuple is requested again for mark format that was already reserved, then it will be reused. If not it will reserve a new entry if space is available. Also on AF init commonly used marker format such as VLAN DEI, IPv4 ECN, IPv4 DSCP are reserved for AF consumers. Signed-off-by:

Introduced reserve_flowkey_alg_idx()to reserve RSS algorithm index, it would internally use set_flowkey_fields() to generate fields based on the flow key dynamically. On AF driver init, it would reserve a predefined set RSS algo indexes, which will be available all the time for all the AF driver consumers. The leftover algo indexes can be reserved at runtime through exiting nix_rss_flowkey_cfg mailbox message. The NIX_FLOW_KEY_TYPE_PORT is removed from predefined a set of RSS flow type as it is not used by any consumer. Signed-off-by:

Introduce state-based algorithm to convert the flow_key value to RSS algo field used by NIX_AF_RX_FLOW_KEY_ALGX_FIELDX register. The outer `for loop` goes over _all_ protocol field and the following variables depict the state machine forward progress logic. a) keyoff_marker - Enabled when hash byte length needs to be accounted in field->key_offset update. b) field_marker - Enabled when a new field needs to be selected. c) group_member - Enabled when a protocol is part of a group. This would remove the existing hard coding and enable to add new protocol support seamlessly. Signed-off-by:

Added response for nix_rss_flowkey_cfg message to return selected RSS algorithm index. The FLOW_KEY_TYPE* definition is part of the mbox message and it will be used by the other consumers of AF driver hence moving to mbox.h. Also renamed FLOW_* definitions to NIX_FLOW_* to avoid global name space collisions, as we have various coming from include/uapi/linux/pkt_cls.h for example. Signed-off-by:

This works by shadowing existing UCAST MCAM entry with a new one additionally matching either NPC_LT_LB_CTAG or NPC_LT_LB_STAG. For this to fully work one needs to send properly configured NIX_VTAG_CFG message afterwards i.e with strip and capture enabled and type set to 0. On receiving tagged packet NIX will remove outer VLAN and capture TCI in NIX_RX_PARSE_S. Also simplified RX Vtag configuration flow With this setting STRIP/CAPTURE VTAG actions separately would be possible. Following combinations are possible: STRIP, STRIP and CAPTURE, CAPTURE or nothing (0 disables respective actions). Signed-off-by:

For a PF/VF with a NIXLF attached has default/reserved MCAM entries for receiving Ucast/Bcast/Promisc traffic. Ideally traffic should be forwarded to NIXLF only after it's contexts are initialized. This patch keeps these default entries disabled and adds mbox messages for a PF/VF to enable these once NPA/NIXLF initialization is done. Likewise while PF/VF is being teared down, it can send the disable mailbox message to stop receiving traffic. Signed-off-by:

Added basic default MKEX profile. This profile tells hardware what data to extract from packet and where to place it (bit offset) in final KEY generated for the parsed packet. Based on the bit placement of the packet data, MCAM entries have to programmed for matching. Also added a msg to retrieve this MKEX profile from PF/VF which inturn can process it to determine how MCAM entry has to be populated. Signed-off-by:

By default NIXLF is set in UCAST mode. This patch adds a new mailbox message which when sent by a RVU PF changes this default mode. When promiscuous mode is needed, the reserved promisc entry for each of RVU PF is setup to match against ingress channel number only, so that all pkts on that channel are accepted and forwarded to the mode change requesting PF_FUNC's NIXLF. PROMISC and ALLMULTI modes are supported only for PFs, for VFs only UCAST mode is supported. Signed-off-by:

This patch adds support for a PF/VF driver to configure NIX transmit scheduler queues via mbox. Since PF/VF doesn't know the absolute HW index of the NIXLF attached to it, AF traps the register config and overwrites with the correct NIXLF index. HW supports shaping, colouring and policing of packets with these multilevel traffic scheduler queues. Instead of introducing different mbox message formats for different configurations and making both AF & PF/VF driver implementation cumbersome, access to the scheduler queue's CSRs is provided via mbox. AF checks whether the sender PF/VF has the corresponding queue allocated or not and dumps the config to HW. With a single mbox msg 20 registers can be configured. Signed-off-by:

Added support for a PF/VF to allocate or free NIX transmit scheduler queues via mbox. For setting up pkt transmission priorities between queues, the scheduler queues have to be contiguous w.r.t their HW indices. So both contiguous and non-contiguous allocations are supported.

This patch adds support for a RVU PF/VF to disable all RQ/SQ/CQ contexts of a NIX LF via mbox. This will be used by PF/VF drivers upon teardown or while freeing up HW resources. A HW context which is not INIT'ed cannot be modified and a RVU PF/VF driver may or may not INIT all the RQ/SQ/CQ contexts. So a bitmap is introduced to keep track of enabled NIX RQ/SQ/CQ contexts, so that only enabled hw contexts are disabled upon LF teardown. Signed-off-by:

Upon receiving notification from firmware the CGX event handler in the AF driver gets the current link info such as status, speed, duplex etc from CGX driver and sends it across to PFs who have registered to receive such notifications. To support above - Mbox messaging support for sending msgs from AF to PF has been added. - Added mbox msgs so that PFs can register/unregister for link events. - Link notifications are sent to PF under two scenarioss. 1. When a asynchronous link change notification is received from firmware with notification flag turned on for that PF. 2. Upon notification turn on request, the current link status is send to the PF. Also added a new mailbox msg using which RVU PF/VF can retrieve their mapped CGX LMAC's current link info. Link info includes status, speed, duplex and lmac type. Signed-off-by:
