Hi Adrian,
The solution is to prevent from allocating pasid table if those
devices are subdevices of the VMD device.
Thanks for your patch!
Is this the only patch that is needed to make VMD devices work in VT-d
scalable mode?
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.
Thank you! So how far should this patch be back ported? Can you please
add a Fixes tag?
