ec0cd287f55f7ea93ff4ccfa4de0f70eca5fef75 - nvmf_che: NVMe-TCP offload support for Chelsio T7 adapters

Mon, 10 Nov 2025 16:50:48 +0100

nvmf_che: NVMe-TCP offload support for Chelsio T7 adaptersThis provides an alternative NVMe over TCP transport which uses PDUoffload for TOE connections on a T7.Similar to iSCSI offload via cxgbei.ko, nvmf_che uses DDP whenpossible to enable the NIC to DMA received data directly into I/O databuffers (pages from a struct bio on the host side, pages from a CTLI/O requests on the controller side) to avoid copying data on the hostCPU. nvmf_che is also able to receive a stream of C2H or H2C PDUs fora single data transfer when using DDP without processing the header ofeach PDU.Unlike cxgbei, nvmf_che aims to be mostly transparent to end users.Notably, neither nvmecontrol or ctld have to be explicitly asked touse an offload. Instead, TCP queue pairs are claimed by this driverwhenever they are eligible (e.g., using TOE).The main restriction of nvmf_che compared to the software TCPtransport is that Chelsio adapters have a restriction on the largestPDU that can be sent and received. When sending data, nvmf_che isable to split large C2H or H2C data requests across multiple PDUswithout affecting nvmf(4) or nvmft(4).To avoid overly large PDUs when using nvmf(4), nvmf_che reports a datatransfer limit that is honored by nvmf(4). This ensures that theremote controller's PDUs will never be too large (since the commandtransfer size is limited to one PDU) and also ensures that nvmf(4)will never to try to send a command PDU with ICD that is too large.For nvmft(4), overly large command PDUs due to ICD are avoided byclamping the size of the reported IOCCSZ in the controller data.However, to ensure that H2C PDUs are sufficiently small, nvmf_che willonly claim queue pairs which advertised a suitable MAXH2CDATAparameter during queue negotiation. For ctld(8), this can be achievedby setting the MAXH2CDATA option in a transport-group, e.g. for T7:transport-group tg0 { discovery-auth-group no-authentication listen tcp 0.0.0.0 listen tcp [::] listen discovery-tcp 0.0.0.0 listen discovery-tcp [::] option MAXH2CDATA 32488}Sponsored by: Chelsio Communications List of files: /freebsd/sys/modules/cxgbe/Makefile

5033c43b7a5c86f71be4058a8209503be2d65c49 - Add a driver for the Chelsio T6 crypto accelerator engine.

Thu, 18 May 2017 00:13:07 +0200

Add a driver for the Chelsio T6 crypto accelerator engine.The ccr(4) driver supports use of the crypto accelerator engine onChelsio T6 NICs in "lookaside" mode via the opencrypto framework.Currently, the driver supports AES-CBC, AES-CTR, AES-GCM, and AES-XTScipher algorithms as well as the SHA1-HMAC, SHA2-256-HMAC, SHA2-384-HMAC,and SHA2-512-HMAC authentication algorithms. The driver also supportschaining one of AES-CBC, AES-CTR, or AES-XTS with an authenticationalgorithm for encrypt-then-authenticate operations.Note that this driver is still under active development and testing andmay not yet be ready for production use. It does pass the tests intests/sys/opencrypto with the exception that the AES-GCM implementationin the driver does not yet support requests with a zero byte payload.To use this driver currently, the "uwire" configuration must be usedalong with explicitly enabling support for lookaside crypto capabilitiesin the cxgbe(4) driver. These can be done by setting the followingtunables before loading the cxgbe(4) driver: hw.cxgbe.config_file=uwire hw.cxgbe.cryptocaps_allowed=-1MFC after: 1 monthRelnotes: yesSponsored by: Chelsio CommunicationsDifferential Revision: https://reviews.freebsd.org/D10763 List of files: /freebsd/sys/modules/cxgbe/Makefile

6af45170c16bdebc1825165e3d6eb5b222e010d8 - Chelsio T4/T5 VF driver.

Wed, 07 Sep 2016 20:13:57 +0200

Chelsio T4/T5 VF driver.The cxgbev/cxlv driver supports Virtual Function devices for ChelsioT4 and T4 adapters. The VF devices share most of their code with theexisting PF4 driver (cxgbe/cxl) and as such the VF device drivercurrently depends on the PF4 driver.Similar to the cxgbe/cxl drivers, the VF driver includes a t4vf/t5vfPCI device driver that attaches to the VF device. It then createschild cxgbev/cxlv devices representing ports assigned to the VF.By default, the PF driver assigns a single port to each VF.t4vf_hw.c contains VF-specific routines from the shared code used tofetch VF-specific parameters from the firmware.t4_vf.c contains the VF-specific PCI device driver and includes itsown attach routine.VF devices are required to use a different firmware request whentransmitting packets (which in turn requires a different CPL messageto encapsulate messages). This alternate firmware request does notpermit chaining multiple packets in a single message, so each packetresults in a firmware request. In addition, the different CPL messagerequires more detailed information when enabling hardware checksums,so parse_pkt() on VF devices must examine L2 and L3 headers for allpackets (not just TSO packets) for VF devices. Finally, L2 checksumson non-UDP/non-TCP packets do not work reliably (the firmware trashesthe IPv4 fragment field), so IPv4 checksums for such packets arecalculated in software.Most of the other changes in the non-VF-specific code are to exposevarious variables and functions private to the PF driver so that theycan be used by the VF driver.Note that a limited subset of cxgbetool functions are supported on VFdevices including register dumps, scheduler classes, and clearing ofstatistics. In addition, TOE is not supported on VF devices, only forthe PF interfaces.Reviewed by: npMFC after: 2 monthsSponsored by: Chelsio CommunicationsDifferential Revision: https://reviews.freebsd.org/D7599 List of files: /freebsd/sys/modules/cxgbe/Makefile

Sat, 26 Dec 2015 07:05:21 +0100

cxgbei: Hardware accelerated iSCSI target and initiator for TOE capablecards supported by cxgbe(4).On the host side this driver interfaces with the storage stack via theICL (iSCSI Common Layer) in the kernel. On the wire the traffic isstandard iSCSI (SCSI over TCP as per RFC 3720/7143 etc.) thatinteroperates with all other standards compliant implementations. Thedriver is layered on top of the TOE driver (t4_tom) and promotesconnections being handled by t4_tom to iSCSI ULP (Upper Layer Protocol)mode. Hardware assistance in this mode includes:- Full TCP processing.- iSCSI PDU identification and recovery within the TCP stream.- Header and/or data digest insertion (tx) and verification (rx).- Zero copy (both tx and rx).Man page will follow in a separate commit in a couple of weeks.Relnotes: YesSponsored by: Chelsio Communications List of files: /freebsd/sys/modules/cxgbe/Makefile
