I can confirm with the patch the NVME drive can be accessed despite the "not
mapping BAR" warning from Xen.
Output log attached.
Thanks a lot for the test, and sorry for the delay in getting back. I
was busy with other stuff and needed some time to figure out the best
way to deal with this. Can you give a try to the patch below? I hope
it will still fix the issue.
No worries, I applied this patch to the latest staging c45e57f59d69,
and the result is also successful NVME drive access.
Output log attached and I see no "failed to sanitize" warnings.
