Subject: [PATCH v2 30/32] hw: define most common PCI types as secure
Date: Fri, 26 Sep 2025 15:01:41 +0100	[thread overview]
Message-ID: <20250926140144.1998694-31-berrange@redhat.com> (raw)
In-Reply-To: <20250926140144.1998694-1-berrange@redhat.com>

Everything except for the simba pci-bridge is relevant to use in
a virtualization use case, so must be considered secure.
