Changes and New Feature History
Feature/Change |
Description |
24.39.2048 |
|
NC-SI Channels |
Added support for two passthrough channels on dual-port adapter cards. |
Expansion ROM |
Added a caching mechanism to improved expansion ROM performance and to avoid any slow boot occurrences when loading the expansion ROM driver. |
Live Migration Support for Image Size above 4GB |
Added support for image size above 4GB when performing a live migration by splitting the image to chunks. |
Crypto Algorithms |
Extended the role-based authentication to cover all crypto algorithms. Now the TLS. IPsec. MACsec. GCM, mem2mem, and NISP work when nv_crypto_conf.crypto_policy = CRYPTO_POLICY_FIPS_LEVEL_2, meaning all cryptographic engines can also work in wrapped mode and not only in plaintext mode. |
DSCP (priority) of ACK Packets |
Added the ability to configure the DSCP (priority) of ACK packets using the ROCE_ACCL access register. |
Performance Improvements |
Added support for large MTU for force loopback QPs to improve performance (using the aes_xts_tweak_inc_64 parameter). This capability is enabled by mlxconfig LARGE_MTU_TWEAK_64 parameter. |
DDR Poison: DDR Uncorrectable Error |
When there is DDR poison (uncorrectable ECC error), firmware reports the health syndrome ICM_FETCH_PCI_DATA_POISONED_ERR (0x14), and triggers the FLR on the the function causing this error. Due to this error, the DDR data is mostly corrupted therefore, the firmware blocks other operations on this function. |
Live Firmware Patch |
Added support for Live Firmware Patch. |
Reserved mkey |
Added new support for reserved mkey index range. When enabled, a range of mkey indexes is reserved for mkey by name use. |
Admin Queue |
Added support for admin queue in virtio device object. |
Enhanced NIC Mode: GGA Modules |
Enabled GGA modules for all working modes (except for RXP) when using Enhanced NIC Mode. |
Bug Fixes |
See Bug Fixes in this Firmware Version section. |
Feature/Change |
Description |
24.38.1002 |
|
INT Packets |
Added support for forwarding INT packets to the user application for monitoring purposes by matching the BTH acknowledge request bit (bth_a). |
Bug Fixes |
See Bug Fixes in this Firmware Version section. |
Feature/Change |
Description |
24.37.1300 |
|
Precision Time Protocol (PTP) |
Added support for Precision Time Protocol (PTP), the protocol used to synchronize clocks throughout a computer network as part of 5T Technology. |
Mergeable Buffer |
Added mergeable buffer support (VIRTIO_NET_F_MRG_RXBUF in virtio spec) for VDPA kernel mode to improve performance in case of large MTU such as 9K. The feature is disabled by default and must be manually enabled while creating or modifying the virtio device. Note: For best performance, it is NOT recommended to enable the feature if the VDPA MTU is set to the default value (1500). |
Monitoring Cloud Guest RoCE Statistics on Cloud Provider |
This new capability enables the VM to track and limit its Vport's activity. This is done using the new q_counters counter which enables aggregation of other Vport's from PF GVMI. |
NVME Device Emulation |
Enables the firmware to generate a Device Change Event upon any change in the NVME Device Emulation object (BAR change, HotPlug power state change, NVME Function reset, etc). |
PCC Algorithms |
Enables a smooth and statically switch between PCC algorithms. In addition, the user can now switch between PCC algorithms while running traffic. |
Hardware Steering: Bulk Allocation |
Added support for 32 actions in the header modify pattern using bulk allocation. |
Bug Fixes |
See Bug Fixes in this Firmware Version section. |
Feature/Change |
Description |
24.35.2000 |
|
PCC Algorithm |
Enables the users to collect more information from NP to RP for PCC algorithm. To achieve this, the NP ingress bytes information was added to the RTT response packet sent from the NP side. |
HPCC: Support per-IP and per-QP methods |
Enables the user to configure the PCC algorithm shaper coalescing mode using nvconfig to select CC algorithm shaper coalescing for IB and ROCE. The new parameters are IB_CC_SHAPER_COALESCE and ROCE_CC_SHAPER_COALESCE. |

Feature/Change |
Description |
24.35.1012 |
|
HPCC, Programmable Congestion Control |
HPCC related configurations in is now supported via the mlxconfig utility. |
UDP |
Added support for copy modify header steering action to/from the UDP field. |
Resource Dump |
Added the following resource dump segments:
|
Striding WQE - Headroom and Tail-room |
As the software requires additional space before and after a packet is scattered for its processing for stridden RQ, the hardware will allocate the required room while scattering packets to spare a copy. |
Connections per Second (CPS) |
Improved security offload's Connections per Second (CPS) rate using the general object DEK (PSP TLS etc). |
VirtIO vDPA Performance Virtualization |
Increased the VirtIO hardware offload message rate to 20/20 MPPS for 256 virtual devices by optimizing the datapath application code. |
Open SNAPI: Communication Channel |
Open SNAPI steering hop optimization:
|
SHA Calculations |
Added support for SHA calculations via the MMO engine. |
UPT Performance |
Optimized latency for UPT traffic. |
NONDNIC, LAG |
Added LAG support on NODNIC interfaces to enable traffic functionality on other ports after the LAG is enabled. |
QoS Priority Trust Default State |
QoS priority trust default state can now be changed using the new nvconfig below:
The values that can be used to set the default state are:
|
VirtIO Full Emulation |
Implemented a transitional device which supports both drivers conforming to the spec 1.x and allows legacy drivers to support virtio legacy driver (virtio 0.95). |
