Subject: [PATCH v3 6/6] vduse: bump version number
Date: Fri, 19 Sep 2025 11:33:59 +0200 [thread overview]
Message-ID: <20250919093359.961296-7-eperezma@redhat.com> (raw)
In-Reply-To: <20250919093359.961296-1-eperezma@redhat.com>
Finalize the series by advertising VDUSE API v1 support to userspace.
Now that all required infrastructure for v1 (ASIDs, VQ groups,
update_iotlb_v2) is in place, VDUSE devices can opt in to the new
features.
