Hi All
This code provides the iommufd support for vdpa device
This code fixes the bugs from the last version and also add the asid support. rebase on kernel
v6,6-rc3
Test passed in the physical device (vp_vdpa), but  there are still some problems in the emulated device (vdpa_sim_net),
I will continue working on it

The kernel code is

It would be better to have a change summary here.

yeah, the version number is also incorrect.

Thanks
