octeontx2: Detect the mbox up or down message via register A single line of interrupt is used to receive up notifications and down reply messages from AF to PF (similarly from PF to its VF). PF acts as bridge and forwards VF messages to AF and sends respsones back from AF to VF. When an async event like link event is received by up message when PF is in middle of forwarding VF message then mailbox errors occur because PF state machine is corrupted. Since VF is a separate driver or VF driver can be in a VM it is not possible to serialize from the start of communication at VF. Hence to differentiate between type of messages at PF this patch makes sender to set mbox data register with distinct values for up and down messages. Sender also checks whether previous interrupt is received before triggering current interrupt by waiting for mailbox data register to become zero.

octeontx2-af: Create BPIDs free pool In current driver 64 BPIDs are reserved for LBK interfaces. These bpids are 1-to-1 mapped to LBK interface channel numbers. In some usecases one LBK interface required more than one bpids and in some case they may not require at all. These usescase can't be address with the current implementation as it always reserves only one bpid per LBK channel. This patch addresses this issue by creating free bpid pool from these 64 bpids instead of 1-to-1 mapping to the lbk channel. Now based on usecase LBK interface can request a bpid using (bp_enable()). This patch also reduces the number of bpids for cgx interfaces to 8 and adds proper error code Signed-off-by: Geetha sowjanya <gakula@marvell.com> Reviewed-by: Simon Horman <horms@kernel.org> Signed-off-by: David S.

So, instead of creating a bit for each combination, we are using upper 4 bits (31:28) in the flow_key_cfg to represent the SRC, DST selection. 31 => L3_SRC, 30 => L3_DST, 29 => L4_SRC, 28 => L4_DST. These won't be part of flow_cfg, so that we don't need to change the existing ABI.

octeontx2-af: Add PTP PPS Errata workaround on CN10K silicon Errata: The ptp_clock_hi rollsover to zero one clock cycle before it reaches one second boundary. As a result, the pps threshold comparison fails after one second and the pps output signal won't toggle further. This patch workarounds the issue by programming the pps_lo_incr register to 500msec minus one clock cycle period, ensuring that the pps threshold comparison succeeds at one second rollover boundary and pps edge toggles. After that point, the driver will have enough time (~500msec) to reset the pps threshold value. After each one second boundary, hrtimer is invoked which resets the pps threshold value.

AF driver uses MAC block with lmac pair to get firmware data etc. These commands will fail as there is no LMAC associated with MAC block.

octeontx2-af: nix and lbk in loop mode in 98xx In 98xx, there are 2 NIX blocks and 4 LBK blocks present. The way these NIX-LBK should be configured depends on the use case. By default loopback functionality is supported in AF VF pairs which are attached to NIX0 and NIX1 LFs alternatively to ensure load balancing. NIX0 transmits a packet to LBK1 which will be received by NIX1 and packet transmitted by NIX1 will get received by NIX0 via LBK2. There are some requirements where only one AF VF is used and respective NIX is expected to operate in a mode where it can receive it own packet back. This can be achieved if NIX0 sends packet to LBK0 and not LBK1. Adding a flag in LF alloc request mailbox which can setup NIX0 to use LBK0 and NIX1 can use LBK3.

The nonstandard way of doing XOR makes the consumer to not predict the queue selection. C0 HW revision onwards, The HW can configure the rss_adder<7:0> as flow_tag<7:0> to align with standard NICs. This patch adds an option to select legacy RSS adder mode vs standard NIC behavior by setting NIX_LF_RSS_TAG_LSB_AS_ADDER flag.

octeontx2-af: cn10k: Bandwidth profiles config support CN10K silicons supports hierarchial ingress packet ratelimiting. There are 3 levels of profilers supported leaf, mid and top. Ratelimiting is done after packet forwarding decision is taken and a NIXLF's RQ is identified to DMA the packet. RQ's context points to a leaf bandwidth profile which can be configured to achieve desired ratelimit.

octeontx2-af: add support for multicast/promisc packet replication feature Currently, multicast packet filtering is accomplished by installing MCAM rule that matches all-multicast MAC address and has its NPC_RX_ACTION set to unicast to PF. Similarly promisc feature is achieved by installing MCAM rule that matches all the traffic received by the channel and unicast the packets to PF. This approach only applies to PF and is not scalable across VFs. This patch adds support for PF/VF multicast and promisc feature by reserving NIX_RX_MCE_S entries from the global MCE list allocated during NIX block initialization. The NIX_RX_MCE_S entries create a linked list with a flag indicating the end of the list, and each entry points to a PF_FUNC (either PF or VF). When a packet NPC_RX_ACTION is set to MCAST, the corresponding NIX_RX_MCE_S list is traversed and the packet is queued to each PF_FUNC available on the list. The PF or VF driver adds the multicast/promisc packet match entry and updates the MCE list with correspondng PF_FUNC. When a PF or VF interface is disabled, the corresponding NIX_RX_MCE_S entry is removed from the MCE list and the MCAM entry will be disabled if the list is empty.

octeontx2-af: cn10k: Add RPM MAC support OcteonTx2's next gen platform the CN10K has RPM MAC which has a different serdes when compared to CGX MAC. Though the underlying HW is different, the CSR interface has been designed largely inline with CGX MAC, with few exceptions though. So we are using the same CGX driver for RPM MAC as well and will have a different set of APIs for RPM where ever necessary. This patch adds initial support for CN10K's RPM MAC i.e. the driver registration, communication with firmware etc. For communication with firmware, RPM provides a different IRQ when compared to CGX. The CGX and RPM blocks support different features. Currently few features like ptp, flowcontrol and higig are not supported by RPM. This patch adds new mailbox message "CGX_FEATURES_GET" to get the list of features supported by underlying MAC. RPM has different implementations for RX/TX stats. Unlike CGX, bar offset of stat registers are different. This patch adds support to access the same and dump the values in debugfs.

octeontx2-af: cn10k: Add mbox support for CN10K platform Firmware allocates memory regions for PFs and VFs in DRAM. The PFs memory region is used for AF-PF and PF-VF mailbox. This mbox facilitates communication between AF-PF and PF-VF. On CN10K platform: The DRAM region allocated to PF is enumerated as PF BAR4 memory. PF BAR4 contains AF-PF mbox region followed by its VFs mbox region. AF-PF mbox region base address is configured at RVU_AF_PFX_BAR4_ADDR PF-VF mailbox base address is configured at RVU_PF(x)_VF_MBOX_ADDR = RVU_AF_PF()_BAR4_ADDR+64KB. PF access its mbox region via BAR4, whereas VF accesses PF-VF DRAM mailboxes via BAR2 indirect access. On CN9XX platform: Mailbox region in DRAM is divided into two parts AF-PF mbox region and PF-VF mbox region i.e all PFs mbox region is contiguous similarly all VFs. The base address of the AF-PF mbox region is configured at RVU_AF_PF_BAR4_ADDR. AF-PF1 mbox address can be calculated as RVU_AF_PF_BAR4_ADDR * mbox size. The base address of PF-VF mbox region for each PF is configure at RVU_AF_PF(0..15)_VF_BAR4_ADDR.PF access its mbox region via BAR4 and its VF mbox regions from RVU_PF_VF_BAR4_ADDR register, whereas VF access its mbox region via BAR4.

In some case we see synchronization issue where after msgs_acked is incremented and before mbox_reset API is called, if current execution is scheduled out and a different thread is scheduled in which checks for msgs_acked. Since the new thread sees msgs_acked == msgs_sent it will try to allocate a new message and to send a new mbox message to PF.Now if mbox_reset is scheduled in, PF will see '0' in msgs_send. This patch fixes the issue by calling mbox_reset before incrementing msgs_acked flag for last processing message and checks for valid message size.

octeontx2-af: Add support for Marvell PTP coprocessor Precision Timestamping block found on Octeontx2 platform is an independent coprocessor and has internal PTP hardware clock. Once configured PTP runs independently and when a packet arrives CGX hardware block gets the current timestamp from PTP block and forwards the packet to NIX by prepending timestamp to the packet. This patch adds the pci driver for PTP block. The driver gets registered by AF driver and does initial configuration and exposes a mailbox function to read and adjust PTP hardware clock. The mailbox function is called by AF consumers like netdev drivers or userspace drivers. Since PTP being a single block in platform this driver helps in accessing PTP block by any AF consumer.

octeontx2-af: Optimize data retrieval from firmware For retrieving info like interface MAC addresses, packet parser key extraction config etc currently a command is sent to firmware and firmware which periodically polls for commands, processes these and returns the info. This is resulting in interface initialization taking lot of time. To optimize this a memory region is shared between firmware and this driver, firmware while booting puts static info like these into that region for driver to read directly without using commands. With this - Logic for retrieving packet parser extraction config via commands is removed and repalced with using the shared 'fwdata' structure. - Now RVU MSIX vector address is also retrieved from this fwdata struct instead of from CSR. Otherwise when kexec/kdump crash kernel loads CSR will have a IOVA setup by primary kernel which impacts RVU PF/VF's interrupts. - Also added a mbox handler for PF/VF interfaces to retrieve their MAC addresses from AF.

Resources here are receive buffer queues (Auras) and pkt notification descriptor queues (CQs). Resources and interface channels are mapped using backpressure IDs (BPIDs). HW supports upto 512 BPIDs, this patch divides these BPIDs statically across CGX/LBK/SDP interfaces as follows. BPIDs 0 - 191 are mapped to LMAC channels, 16 per LMAC. BPIDs 192 - 255 are mapped to LBK channels. BPIDs 256 - 511 are mapped to SDP channels. Also did the needed basic configuration of BPIDs.

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.

octeontx2-af: Support for changing RSS algorithm This patch adds support for a RVU PF/VF to change NIX Rx flowkey algorithm index in NPC RX RSS_ACTION. eg: a ethtool command changing RSS algorithm for a netdev interface would trigger this change in NPC. If PF/VF doesn't specify any MCAM entry index then default UCAST entry of the NIXLF attached to PF/VF will be updated with RSS_ACTION and flowkey index.

octeontx2-af: NIX Tx scheduler queue config support 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.

octeontx2-af: NIX Tx scheduler queues alloc/free 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. Upon receiving NIX_TXSCH_FREE mbox msg all scheduler queues allocated to sending PFFUNC (PF/VF) will be freed. Selective free is not supported.

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.

octeontx2-af: Forward CGX link notifications to PFs 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.
