Subject: [PATCH v2 07/15] iommu/uapi: Add iommu_gpasid_unbind_data
Date: Thu, 11 Jun 2020 05:15:26 -0700 [thread overview]
Message-ID: <1591877734-66527-8-git-send-email-yi.l.liu@intel.com> (raw)
In-Reply-To: <1591877734-66527-1-git-send-email-yi.l.liu@intel.com>
Existing iommu_gpasid_bind_data is used for binding guest page tables
to a specified PASID. While for unwind it, a unbind_data structure is
needed.
