Subject: [dpdk-dev] Why do we need iommu=pt?
Date: Mon, 20 Oct 2014 14:58:54 -0700 [thread overview]
Message-ID: <CAKU5Fo_7fQHcYa-1ZBX8=D0SCkxZL8VLEpWYtJ6rG4DpV=g3gw@mail.gmail.com> (raw)
Hi,
My question is that if the Poll mode driver used the DMA kernel interface
to set up its mappings appropriately, would it still require that iommu=pt
be set?
What is the purpose of setting iommu=pt ?
Thank you.
