From 7be423336eccc872249d37900c19c1d24f171353 Mon Sep 17 00:00:00 2001 From: Lu Baolu Date: Fri, 8 Dec 2023 09:53:14 +0800 Subject: [PATCH] iommu: Set owner token to SVA domain Commit a9c362db3920 ("iommu: Validate that devices match domains") added an owner token to the iommu_domain. This token is checked during domain attachment to RID or PASID through the generic iommu interfaces. The SVA domains are attached to PASIDs through those iommu interfaces. Therefore, they require the owner token to be set during allocation. Otherwise, they fail to attach. Set the owner token for SVA domains.
