Subject: [virtio-dev] [PATCH 07/11] transport-pci: Introduce transitional MMR device id
Date: Fri, 31 Mar 2023 01:58:30 +0300 [thread overview]
Message-ID: <20230330225834.506969-8-parav@nvidia.com> (raw)
In-Reply-To: <20230330225834.506969-1-parav@nvidia.com>
Transitional MMR device PCI Device IDs are unique. Hence,
any of the existing drivers do not bind to it.
This further maintains the backward compatibility with
existing drivers.
