Linux 6.13 RDMA Changes Headlined By NVIDIA's New Data Placement Ordering Feature
The RDMA subsystem updates were sent out last Friday for the ongoing Linux 6.13 kernel cycle
Most notable with the RDMA updates is the NVIDIA Mellanox "MLX5" network driver introducing a new Data Direct Placement (DDP) feature to further help with performance. With Data Direct Placement the intent is on achieving higher bandwidth by permitting responders to receive packets out of order. It will be interesting to see the DDP performance advantages in practice but so far on the prior patches I haven't seen any numbers to quantify it from NVIDIA.
