Wish help and concern about Intel IGD iommu passthrough for our IDV product plan！

[Acewind]

Hi, We are cloud desktop product and solution vendor in China.
Intel IGD iommu passthrough is core tech point in our idv plan.

I have test IGD passthrough on Ubuntu 18.04/CentOS 7/Fedora 25，and with
graphic hardware：
00:02.0 VGA compatible controller: Intel Corporation Iris Graphics 540 (rev
0a)
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 530 (rev
06)
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor
Integrated Graphics Controller (rev 06)
00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated
Graphics Controller (rev 09)
...
Sometimes ok and sometime not.
I have asked and discussed in vfio and intel gvt mail lists.
We wish more help from intel engineers, thank for your concern!

Best Regards,
Acewind
