From 965bc083103e1359679932feb6aadd35359c24ae Mon Sep 17 00:00:00 2001 From: Eric Auger Date: Tue, 27 Feb 2024 17:55:48 +0100 Subject: qdev: Add a granule_mode property MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Introduce a new enum type property allowing to set an IOMMU granule. Values are 4k, 8k, 16k, 64k and host. This latter indicates the vIOMMU granule will match the host page size. A subsequent patch will add such a property to the virtio-iommu device.
