Security Hardening Enhancements: This release contains important reliability improvements and security hardening enhancements. NVIDIA recommends upgrading your devices firmware to this release to improve the devices’ firmware security and reliability.
SR-IOV - Virtual Functions (VF) per Port - The maximum Virtual Functions (VF) per port is 127. For further information, see RoCE Limitations.
It is recommended to enable the “above 4G decoding” BIOS setting for features that require large amount of PCIe resources.
Such features are: SR-IOV with numerous VFs, PCIe Emulated Switch, and Large BAR Requests.
Feature/Change | Description |
26.33.1048 | |
MADs | Added a new MAD of class SMP that has the attributes hierarchy_Info as defined in the IB Specification and is used to query the hierarchy information stored on the node and the physical port. |
NV Configurations via the Relevant Reset Flow | Added pci_rescan_needed field to the MFRL access register to indicate whether a PCI rescan is needed based on the NV configurations issued by the software. |
VF Migration | Added support for VF migration. The hypervisor can now suspend its VF, meaning from that point the VF cannot perform action such as send/receive traffic or run any command. In this firmware version only the suspend resume mode is supported (on the same VM). |
VF Migration | Added support for VF migration. |
ICM Pages | Added a new register (vhca_icm_ctrl access_reg) to enable querying and limiting the ICM pages in use. |
XRQ QP Errors Enhancements | Enhanced the XRQ QP error information provided to the user in case QP goes into an error state. In such case, QUERY_QP will provide information on the syndrome type and which side caused |
ibstat | Updated the ibstat status reported when the phy link is down. Now QUERY_VPORT_STATE.max_tx_speed of UPLINK will not be reported as 0 anymore. |
NetworkPort Schema Replacement | Replaced the deprecated NetworkPort schema with Port schema in NIC RDE implementation. |
SW Steering Cache | Modified the TX or RX cache invalidation behavior. TX or RX cache invalidation now does not occur automatically but only when the software performs the sync operation using the using sync_steering command. |
Firmware Steering | Enabled the option to modify the ip_ecn field in the packet header in firmware steering. |
Mega Allocations in Bulk Allocator Mechanism | Modified the maximum bulk size per single allocation from "log_table_size - log_num_unisizes", to allocate any range size, to remove limitations that HWS objects such as counters and modify arguments might encounter. |
