[PATCH 0/4] vDPA: API for reporting IOVA range
Hi All:
This series introduces API for reporing IOVA range. This is a must for
userspace to work correclty:
- for the process that uses vhost-vDPA directly to properly allocate
IOVA
- for VM(qemu), when vIOMMU is not enabled, fail early if GPA is out
of range
- for VM(qemu), when vIOMMU is enabled, determine a valid guest
address width
Please review.
Thanks
