Subject: [RFC 6/8] vfio: Rename and remove compat from noiommu set function
Date: Mon, 1 Dec 2025 09:30:10 -0800 [thread overview]
Message-ID: <20251201173012.18371-7-jacob.pan@linux.microsoft.com> (raw)
In-Reply-To: <20251201173012.18371-1-jacob.pan@linux.microsoft.com>
With the dummy iommu driver, noiommu mode can be supported beyond
vfio_compat mode under IOMMUFD. Rename it accordingly.
