How to verify GPUDirect Storage's P2P DMA is working correctly for local attached NVMe SSD?

Hi,

I am testing GPUDirect Storage for local attached NVMe SSDs with H100. My environment is as follows:

The gdsio_verify tests and gdsio benchmarks work okay with compatibility mode set to false:

sudo ./gdsio_verify -f /gds-test/gdsio.0 -n 1 -m 0 -s 4k -o 0 -d 0 -t 0
gpu index :0,file :/gds-test/gdsio.0, gpu buffer alignment :0, gpu buffer offset :0, gpu devptr offset :0, file offset :0, io_requested :4096, io_chunk_size :4096, bufregister :true, sync :0, nr ios :1,
fsync :0,
Batch mode: 0
Data Verification Success

However, I see the following ERROR in the cufile.log of the above gdsio_verify test. These errors show up in all gdsio benchmarks:

And I see the following in the dmesg log:

[69036.183347] nvidia-fs:nvfs_pci: no hash entry for pdevinfo:0000:5c:00.0
[69036.189129] nvidia-fs:nvfs_pci: no hash entry for pdevinfo:0000:5c:00.0

Can someone help with explaining what the ERROR messages mean and what does the dmesg log indicate? Also, how do I confirm that gdsio benchmarks are using P2P DMA?
