Changes and New Feature History

24.43.1014

RDMA Telemetry

Added the option to indicate an error CQE event on every selected function per eSwitch manager. This indication is defined as a new WQE including the relevant information about the error (such as: syndrome, function_id, timestamp, QPs num etc.).

The feature is configured using a new general object: RDMA-Telemetry object, and depends on the following new caps: HCA_CAP.rdma_telemetry_notification_types and HCA_CAP.rdma_telemetry.

UID Permissions

Extended kernel lockdown permission set. The following sub-operations can now be called by tools (permission TOOLS_RESORCES) using new HCA capability bitmask field: tool_partial_cap.

The 5 sub-operations are:

• QUERY_HCA_CAP with other function

• QUERY_VUID with direct data

• QUERY_ROCE_ADDRESS with other vport

• SET_HCA_CAP with other function

• POSTPONE_CONNECTED_QP_TIMEOUT with other vport

The new added caps are:

• tool_partial_cap.postpone_conn_qp_timeout_other_vport,

• tool_partial_cap.set_hca_cap_other_func

• tool_partial_cap.query_roce_addr_other_vport

• tool_partial_cap.query_vuid_direct_data

• tool_partial_cap.query_hca_cap_other_func

Jump from NIC_TX to FDB_TX

Added 'table_type_valid' and 'table_type' fields to the steering action (STC) "Jump To Flow" table parameters to enable the user to jump from NIC_TX to FDB_TX and bypass the ACL table.

Jump to TIR or queue from FDB on Tx

Enabled hop reduction by bypassing NIC domain in various use cases. Such action r educes the number of hops (improves PPS) to deal with mass number of flows and devices.

To enable this new capability, a new STC action type "JUMP_TO_FDB_RX" was added to allow jumping into the RX side of a table.

Hotplug/Unplug on VirtIO Devices when the Host is Powered OFF

Enabled hotplug/hotunplug during device's power off or power cycle to prevent the device from getting stuck.

2-steps-hotplug

Added support for 2-steps-hotplug capability. The device is plugged with "free" status by default, and it will not appear on the bus until being modified to "hotplug" status.

24.42.1000

Steering SF Traffic to a Specific PF MSI-X

MSI-X on SF can be received now through the PF's MSI-X vector.

Memory Slow Release

Added a new command interface "Memory slow release" to enable/disable holding memory pages for a defined period of time. Once the timer expires, the firmware will return the pages to the driver.

Hotplug Power Off for Virtio FS

Added support for Hotplug Power Off for Virtio FS (hotplug_power_off).

Kernel Lockdown

Added support for MVTS register via a miscellaneous driver using the access_register PRM command.

24.41.1000

TRNG FIPS Compliance

Implemented Deterministic Random Bit Generator (DRBG) algorithm on top of firmware TRNG (the source for raw data input) in accordance with NIST SP800-90A.

vDPA Live Migration

Added support for vDPA virtual queue state change from suspend to ready, and discrete mkey for descriptor. vDPA Live Migration uses these two new capabilities to reduce downtime since vq can go back to ready state for traffic and descriptor-only-mkey can help reduce mkey mapping time.

NVConfig

Added a new NVConfig option to copy AR bit from the BTH header to the DHCP header.

Steering

Added the option provide field's offset and length in Steering add_action option.

Flex Parser Merge Mechanism

Extended Flex Parser merge mechanism to support hardware capabilities.

Flex Parser

Enabled the option to disable the native parser when the parse graph node is configured with the same conditions.

Flex Parser

Added support for father/son headers parsing.

LRO

Added support for tunnel_offload in LRO.

32.39.2048

Socket Direct Single netdev Mapped to Two PCIe Devices

Enabled Single Netdev mapping to two PCIe devices (Socket Direct).

Now multiple devices (PFs) of the same port can be combined under a single netdev instance. Traffic is passed through different devices belonging to different NUMA sockets, thus saving cross-NUMA traffic and allowing apps running on the same netdev from different NUMAs to still feel a sense of proximity to the device and achieve improved performance.

The netdev is destroyed once any of the PFs is removed. A proper configuration would utilize the correct close NUMA when working on a certain app/CPU.

Currently, this capability is limited to PFs only, and up to two devices (sockets). To enable the feature, one must configure the same Socket Direct group (non zero) for both PFs through mlxconfig SD_GROUP.

ACL

Added support for egress ACL to the uplink by adding a new bit to the Set Flow Table Entry: allow_fdb_uplink_hairpin.
