NVDA GPU Driect RDMA support in Windows with Libfabric

[sen-sd]

Is libfabric support GPU Driect RDMA. Based on code I found some information like it support for linux.
prov\psm3\psm3\psm_rndv_mod.c
static uint64_t get_nvidia_bar_addr(int domain, int bus, int slot) -> in this function it is reading bus address with Linux API call.
Please confirm GPU Driect RDMA support for Windows is available or not.

No, AFAIK, the Windows OS does not support the necessary kernel mechanism required to setup PCI peer-to-peer device transfers, or expose such a mechanism to user-space.

The Linux OS mechanism is known as dma-buf.
