Yes, it is. With this patch, the system can boot successfully and the RAID device connected to the VMD device can be recognized by the host OS. I also ran a simple IO stress on the RAID device by compiling kernel `$ make -j $(nproc)`. Everything looks good. -- Adrian _______________________________________________ iommu mailing list [email protected] https://lists.linuxfoundation.org/mailman/listinfo/iommu
