CX6-DX NIC NIC FW: 22.39.2048 Note: If the CX6-DX NIC is used to run RU emulator on dual ports, downgrade the NIC FW to 22.35.1012 due to a known issue.
DOCA OFED 23.10-1.1.9 Note: DOCA OFED is only required by Grace Hopper platform. It is not required for x86 platform.
NVIDIA-peermem Note: Aerial has been using kernel DMA-buf instead of nvidia-peermem since 23-4 release. It is not required anymore.

GPU AX800, A100X, A100, GH200 (Early Access)

Aerial has been using DMA-buf, inbox driver and OpenRM driver since 23-4 release. So MOFED and nvidia-peermem are not needed anymore. On the x86 platform, the 5.15 kernel with DMA-buf and inbox driver are used. On the Grace Hopper platform, the 6.2 kernel with DMA-buf and DOCA OFED are used.
