Subject: [PATCH v7 11/12] iommu: Assign the direct mapped domain to group->domain
Date: Fri, 25 Nov 2016 13:13:18 +0800 [thread overview]
Message-ID: <1480050799-1237-12-git-send-email-bhe@redhat.com> (raw)
In-Reply-To: <1480050799-1237-1-git-send-email-bhe@redhat.com>
In iommu_request_dm_for_dev(), devices of group have all been attached
to newly created direct mapped domain. We should store the domain into
group->domain so that it works for iommu_get_domain_for_dev() and
get_domain().
