From b68ba1ca57677acf870d5ab10579e6105c1f5338 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Eugenio=20P=C3=A9rez?= Date: Mon, 16 Nov 2020 17:55:04 +0100 Subject: memory: Add IOMMU_NOTIFIER_DEVIOTLB_UNMAP IOMMUTLBNotificationType MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This allows us to differentiate between regular IOMMU map/unmap events and DEVIOTLB unmap. Doing so, notifiers that only need device IOTLB invalidations will not receive regular IOMMU unmappings. Adapt intel and vhost to use it.
