Feature/Change |
Description |
|
22.39.1002 |
|
|
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. |
|
Programmable Congestion Control |
Programmable Congestion Control is now the default CC mechanism. ZTR_RTTCC is the default CC algorithm when ECE is enabled and the CC algorithm negotiation succeeds, otherwise PCC DCQCN will be used. |
|
Reserved mkey |
Added new support for reserved mkey index range. When enabled, a range of mkey indexes is reserved for mkey by name use. |
