From 1b48dc03e575a872404f33b04cd237953c5d7498 Mon Sep 17 00:00:00 2001 From: Jason Wang Date: Fri, 23 Oct 2020 17:00:42 +0800 Subject: vhost: vdpa: report iova range This patch introduces a new ioctl for vhost-vdpa device that can report the iova range by the device. For device that implements get_iova_range() method, we fetch it from the vDPA device. If device doesn't implement get_iova_range() but depends on platform IOMMU, we will query via DOMAIN_ATTR_GEOMETRY, otherwise [0, ULLONG_MAX] is assumed. For safety, this patch also rules out the map request which is not in the valid range.
