Changes and New Features
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.
When upgrading or changing the configuration on multi-host adapter cards, for the changes to take effect, PCIe restart must be simultaneously sent from both hosts (servers).
To do so, perform the following:
1. Shut down the server with the auxiliary card.
2. Shut down the server with the primary card.
3. Bring back the server with the primary card.
4. Bring back the server with the auxiliary card.
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.
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.
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.
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
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.
Disabled the option to send SMPs from unauthorized hosts.
Enabled the option to modify the ip_ecn field in the packet header in firmware steering.
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.
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.
Changing all the Crypto Features to Wrapped or Cleartext
Crypto features can be in either wrapped or unwrapped mode. Meaning, the key can be wrapped or in plaintext when running the CREATE_DEK PRM command. To comply with the requirements specified in FIPS publication, all the created DEKs must be wrapped.
This feature adds new NV_CONFIG per device to control this mode, and enables the user to change all the crypto features to wrapped or cleartext.
