IAA-config：wq error - no shared wq support (platform configuration error)

I want to use IAA, but I am in trouble.

I run the configuration script providedd by intel. I get this:
`no shared wq support (platform configuration error)`

when I run `dmesg | grep idxd` I get:
`root@node190:~/IAA# dmesg | grep idxd

the command `cat /proc/cmdline`shows:
`intel_iommu=on,sm_on iommu=on`

If I use dedicate mode the code print error:
`threshold attribute write failed: Invalid argument`
