Subject: [PATCH v2 04/17] vdpa_sim: remove the limit of IOTLB entries
Date: Thu, 26 Nov 2020 15:49:37 +0100 [thread overview]
Message-ID: <20201126144950.92850-5-sgarzare@redhat.com> (raw)
In-Reply-To: <20201126144950.92850-1-sgarzare@redhat.com>
The simulated devices can support multiple queues, so this limit
should be defined according to the number of queues supported by
the device.
Since we are in a simulator, let's simply remove that limit.
